  • Compared Biology of the Native Rabbit (Sylvilagus sp.) and the European
           Domestic Rabbit (Oryctolagus sp.) with a Background of Rabbit Consumption
           in a Venezuelan City

    • Abstract: Resumen Las diferencias biológicas entre el conejo criollo Sylvilagus sp. (Lagomorpha: Leporidae) y el conejo europeo (Oryctolagus sp.) son poco conocidas entre cunicultores de Latinoamérica, bien sea porque la cunicultura es una explotación menor, comparada con las de otras especies de animales domésticos, o porque la enseñanza de esta materia en estudios universitarios es escaza. El objetivo central de esta investigación fue examinar comparativamente las diferencias existentes entre conejos Sylvilagus sp. y Oryctolagus sp., en relación con su biología, consumo y explotación comercial. Para ello se usó el sistema del metanálisis de trabajos científicos publicados sobre el tema, noticias de prensa y entrevistas realizadas a consumidores en el lapso del 2000 al 2019. Se tomaron en cuenta características morfológicas, fisiológicas, de origen genético y su comportamiento con relación al medio ambiente. Se organizaron y analizaron estas características para establecer las posibles semejanzas y diferencias entre ambos géneros. Como la familia Leporidae comprende tres géneros en Suramérica, se incluyó el género Lepus sp. solo en un cuadro comparativo de géneros. Se encontraron diferencias biológicas, genéticas y reproductivas significativas entre los géneros Sylvilagus sp. y Oryctolagus sp. que pueden ser imperceptibles para cunicultores inexpertos; por ende, se buscó hacer notar las características de cada género para su identificación práctica. Se determinó que el consumo de la carne de conejo depende de la disponibilidad que exista en el mercado.Abstract Biologic differences between the native rabbit Sylvilagus sp. (Lagomorpha: Leporidae) and the European rabbit (Oryctolagus sp.) are quite unknown among Latin-American rabbit-breeders, either since rabbit-breeding is scarcely exploited as compared to other species of domestic animals or because this subject is taught very unusually in the college education. This research is aimed at examining comparatively the differences between Sylvilagus sp. and Oryctolagus sp. rabbits regarding their biology, consumption, and business exploitation. To do so, a meta-analysis was carried out on different scientific works dealing with this topic, news, and interviews to consumers during the term 2000 to 2019. Morphological, physiological, and genetic-origin characteristics were considered as well as how they behave in relation to the environment. These characteristics were organized and analyzed to determine the potential similarities and differences between both genuses. As the family Leporidae includes three genuses in South America, then the genus Lepus sp. was included only in a genus comparative table. Significant biologic, genetic and reproductive differences between Sylvilagus sp. And Oryctolagus sp. were found but they can be unnoticed to the unexpert rabbit-breeders. Therefore, characteristics typical to each genus were highlighted to allow a practical identification. It was determined that the consumption of rabbit meat depends on the availability in the market.
       
  • Characterization of the Feeding Practices in Colombian Native Horses using
           Feeding-Throughs

    • Abstract: Resumen Se presume que la alimentación de equinos en régimen de pesebreras es empírica en el departamento de Antioquia. El objetivo del presente artículo es caracterizar los métodos de alimentación para el caballo criollo colombiano estabulado. Para ello, se visitaron 14 pesebreras (103 equinos) donde se recopiló la siguiente información: edad, estado fisiológico (gestando, lactando, en crecimiento, intensidad del trabajo) peso, condición corporal, ración (peso de cada alimento suministrado en 24 horas) de los animales. Se calculó el balance de energía digestible y proteína bruta, consumo de materia seca y relación forraje/concentrado según estado fisiológico. Como resultado se obtuvo que un porcentaje alto de individuos presenta obesidad y realiza trabajo físico entre leve y moderado. La gran mayoría de pesebreras suministra la ración divida en tres tomas al día y la relación forraje/concentrado en el 28,6 % de casos fue inadecuada. El consumo de materia seca expresada en porcentaje con base en el peso vivo arrojó un promedio de 2,5 %, con unos rangos que van de 1,6 a 3,4 %. El balance nutricional de la energía mostró que existen 15 animales (14,5 %) en equilibrio; con exceso, se encontraron 84 (81,5 %). El balance de la proteína arrojó que en equilibrio estaban 6 animales (5,8 %); con exceso, se encontraron 85 (82,5 %), y en déficit 12 (11,6 %). En conclusión, dividir la ración en tres porciones para el día, la relación forraje / concentrado inadecuada, la oferta de materia seca sin considerar el estado fisiológico, y el exceso de energía digestible y proteína bruta de la ración, son falencias frecuentes que predisponen a patologías digestivas y laminitis.Abstract There is an assumption that the feeding of horses with feeding-through is empirical in the Antioquia Province. This article aims to characterize the feeding methods of the Colombian native horses kept in stables. To do so, 14 feeding-throughs were visited (103 horses), and the following information was gathered: age, physiological status (pregnant, lactating, growing, work intensity), weight, body condition, ration (weight of each 24-hours food piece provided). The balance between digestible energy and gross protein, dry matter consumption, and the ratio forage/concentrate based on their physiological status were calculated. It was found that a high percentage of subjects are obese and do mild-to-moderate physical work. Most of the feeding-throughs provide the daily ration divided into three takes per day, and the ratio forage/concentrate was inappropriate in 28.6% of the subjects. Based on the living weight, consumption of dry matter given in percentage was found at an average of 2.5%, ranging from 1.6 to 3.4%. The nutritional balance of energy indicated 15 subjects (14.5%) in equilibrium. In excess were found 84 subjects (81.5%). The protein balance indicated six subjects in equilibrium (5.8%). In excess were found 85 subjects (82.5%). Twelve subjects were found in deficit (11.6%). In conclusion, dividing the ration into three takes per day leads to an inappropriate ratio of rofage/concentrate. Providing the dry matter without considering the physiological status and the excess of digestible energy and gross protein in the ration are also frequent fallencies that predispose the subjects to digestive pathologies and laminitis.
       
  • Indirect Hemagglutination Test in the Detection of Antibodies against
           Toxoplasma gondii in Venezuelan Felids

    • Abstract: Abstract Current knowledge of Toxoplasma gondii infection in Venezuelan ecosystems is limited. Mammals and birds are intermediate hosts, and felid species are definitive hosts. In most human-altered habitats, the domestic cat is the predominant definitive host. Cats are important in the epidemiology of T. gondii infection because they are the only hosts that can excrete environmentally resistant oocysts. Other carnivores can be infected consuming tissue cysts when feeding on infected animals and by incidental ingestion of oocysts from environmental contamination. This study aimed to quantify the values of antibodies for T. gondii in blood serum of some felids’ species employing the technique of indirect hemagglutination. In the present study, seropositivity of T. gondii was determined in serum of 35 animals (22 stray cats and 13 wild cats) from Venezuela, South America. Antibodies to T. gondii were found in 21 of 22 (95.45 %) stray cats’ titers of 1:64 in four, 1:128 in four, 1:256 in one, 1:512 in one, 1:1024 in three, and 1:2048 or higher in eight. In four of six (66.67 %) ocelots’ titers of 1:64 in one, 1:256 in one, 1:1024 in one, and one with titers 1:2048. In three of four (75.00 %) jaguars’ titers of 1:512 in one, and two with titers 1:2048. The Kruskal-Wallis test showed a statistically significant difference between species (H = 8.413, p = 0 .015).Resumen El conocimiento actual de la infección por Toxoplasma gondii en los ecosistemas venezolanos es limitado. Los mamíferos y las aves son hospedadores intermedios y los félidos son hospedadores definitivos. En la mayoría de los hábitats alterados por el hombre, el gato doméstico es el hospedador definitivo predominante. Los gatos son importantes en la epidemiología de la infección por T. gondii porque son los únicos hospedadores que pueden excretar los ooquistes resistentes al medio ambiente. Otros carnívoros pueden infectarse por el consumo de quistes tisulares al alimentarse de animales infectados y por la ingestión incidental de ooquistes procedentes de la contaminación ambiental. Este estudio tuvo como objetivo cuantificar los valores de anticuerpos para T. gondii en el suero sanguíneo de algunas especies de félidos mediante la técnica de hemoaglutinación indirecta. En el presente estudio se determinó la seropositividad de T. gondii en el suero de 35 animales (22 gatos callejeros y 13 felinos silvestres) de Venezuela, Sudamérica. Los anticuerpos contra T. gondii se encontraron en 21 de 22 (95,45 %) gatos callejeros con títulos de 1:64 en cuatro, 1:128 en cuatro, 1:256 en uno, 1:512 en uno, 1:1024 en tres y 1:2048 o más en ocho. En cuatro de seis (66,67 %) ocelotes con títulos de 1:64 en uno, 1:256 en uno, 1:1024 en uno, y uno con títulos 1:2048. En 3 de 4 (75,00 %) jaguares con títulos de 1:512 en uno, y dos con títulos 1:2048. La prueba de Kruskal-Wallis mostró una diferencia estadísticamente significativa entre las especies (H = 8,413, p = 0,015).
       
  • Ingluviotomia para remoção de corpo estranho em calopsita doméstica
           (Nymphicus hollandicus). Relato de caso

    • Abstract: Resumo As aves apresentam anatomia e fisiologia únicas. Seu sistema digestório é composto por esôfago, estômago (proventrículo e ventrículo), intestino delgado e intestino grosso. O esôfago apresenta uma dilatação chamada de inglúvio na maioria das aves, que armazena alimentos. Lesões e massas nesses locais ocorrem por diversos motivos, provocando dificuldades alimentares e emagrecimento. A ingestão de substâncias inadequadas pode formar uma massa, repousar no papo e gerar possível intoxicação. O objetivo do trabalho foi descrever um caso de ingluviotomia decorrente de ingestão de corpo estranho em calopsita (Nymphicus hollandicus). A ingluviotomia é um procedimento cirúrgico de urgência, podendo ser optado para a remoção de corpo estranho no inglúvio, sendo que a resolução cirúrgica do problema e a recuperação clínica ocorre sem maiores problemas desde que empregada um conduta clínico-cirúrgica adequada.Resumen Los pájaros tienen una anatomía y fisiología únicas. Su sistema digestivo consta de esófago, estómago (proventrículo y ventrículo), intestino delgado e intestino grueso. En la mayoría de los pájaros, el esófago tiene una dilatación llamada ingluvie que almacena alimento. En este lugar pueden ocurrir lesiones y masas debido a varias razones, ocasionando dificultades dietarias y pérdida de peso. La digestión de sustancias inadecuadas puede formar una masa, quedarse ahí hasta germinar e intoxicarse. El objetivo de este estudio es hacer un informe de una ingluviotomía debido a la ingestión de un cuerpo extraño en una cacatúa ninfa (Nymphicus hollandicus). La ingluviotomía es un procedimiento quirúrgico de urgencia y se puede escoger para remover un cuerpo extraño en el ingluvium. La resolución quirúrgica del problema y la recuperación clínica ocurren sin mayores problemas si se usa un enfoque clínico-quirúrgico adecuado.Abstract Birds have a unique anatomy and physiology. Their digestive system consists of esophagus, stomach (proventricle and ventricle), small intestine and large intestine. The esophagus has a dilatation called ingluvies in most birds, which stores food. Injuries and masses in these places can occur for several reasons, causing dietary difficulties and weight loss. Ingestion of inappropriate substances can form a mass, rest in the crop and cause intoxication. The aim of this study was to describe a case of ingluviotomy resulting from the ingestion of a foreign body in cockatiel (Nymphicus hollandicus). Ingluviotomy is an urgent surgical procedure, and it can be chosen to remove a foreign body in the ingluvium. The surgical resolution of the problem and clinical recovery occur without major problems as long as an appropriate clinical-surgical approach is used.
       
  • Croup Conformation and Caslick's index in Peruvian Paso Mares

    • Abstract: Resumen El objetivo de este estudio fue determinar el índice de Caslick en yeguas de la raza caballo peruano de paso y su relación con la conformación de grupa (ángulo de inclinación de grupa y tipo de inserción de cola). Se tomaron medidas morfométricas para hallar el índice de Caslick, la inclinación de grupa y la inserción de cola en yeguas participantes del LXX Concurso Nacional Oficial de Caballos Peruanos de Paso (n = 98). La media del ángulo de inclinación de grupa fue 37,23° ± 4,88°. La mayoría de las yeguas presentó una alta inserción de cola (55,1 %), y el índice de Caslick promedio fue de 42,68 ± 35,05. Más del 90 % de yeguas tuvo una buena conformación vulvar. Se concluyó que no hubo relación entre la inserción de cola y el índice de Caslick (p > 0,05), ni tampoco una correlación entre la edad e inclinación de grupa vs. el índice de Caslick (ρ = -0,187 y 0,042, respectivamente; p > 0,05). Sin embargo, se encontró una correlación negativa entre el número de partos y el índice de Caslick (ρ = -0,264; p < 0,05).Abstract This study aims to determine the Caslick's Index in Peruvian Paso mares and how it relates to the croup conformation (croup inclination angle and type of tail insertion). To find the Caslick's Index, croup inclination, and tail insertion, some morphometric measures were made in the mares that participated in the LXX Official National Contest of Peruvian Paso Horses (n = 98). The mean for the croup inclination angle was 37.3° + 4.88°. Most of the mares showed a high tail insertion (55.1 %), and the average mean Caslick's Index was 42.68 + 35.05. More than 90% of the mares had a good vulvar conformation. It was concluded that there was no relationship between the tail insertion and the Caslick's Index (p > 0.05), nor any correlation between age and croup inclination vs. Caslick's Index (ρ = -0.187 and 0.042, respectively; p > 0.05). However, a negative correlation was found between the number of labors and the Caslick's Index (ρ = -0.264; p < 0.05).
       
  • Sediment Composition of the System Affluent-Oxidation Pool-Effluent in an
           Intensive Farm of Oncorhynchus mykiss

    • Abstract: Resumen El sedimento es la capa superficial del fondo en estanques o en lagunas de oxidación. Este se origina fundamentalmente por la deposición de sólidos en suspensión, nutrientes y partículas del suelo que están en contacto con el agua, y que son naturalmente producidos por la operación de las granjas. Su manejo y disposición se constituye actualmente en un imperativo técnico, dadas las implicaciones ambientales que tienen las descargas provenientes de cultivos piscícolas. Se realizó la caracterización general del sedimento en tres sectores de una granja intensiva de producción, afluente, laguna de oxidación y efluente, la cual incluyó cuatro parámetros, que fueron medidos en tres momentos diferentes. Los valores obtenidos fueron comparados mediante análisis de varianza de una vía con α = 0,05 como nivel de significancia. Además, cuando fue necesario se realizó una prueba de Tukey para precisar las diferencias. Aquello cobijó las medidas de fósforo disponible, materia orgánica, carbono orgánico y relación C: N. Las diferencias encontradas entre los sectores son una aproximación al efecto de la producción piscícola sobre la composición de los sedimentos.Abstract Sediment is the surface layer in the bottom of ponds or oxidation pools. It is created basically due to the deposition of solids in suspension, nutrients, and soil particles that contact the water and are produced naturally in farming operations. Today, the management and arrangement are a must in technical issues due to the environmental implications generated by the discharges coming from fish cultures. The general characterization of the sediment was carried out in three sectors of an intensive production farm, affluent, oxidation pool, and effluent. It included four parameters that were measured in three different time points. Obtained values were compared using one-way variance analysis with α = 0.05 as the significance level. In addition, when necessary, a Tukey test was carried out to pin down the differences. It enabled us to find the measures of available phosphorus, organic matter, organic carbon, and the ratio C: N. the differences found between the sectors are approximate values to the effect of the fish production regarding the sediment composition.

    • Abstract: Resumen El aborto enzootico ovino es una enfermedad causada por Chlamydia abortus. Es considerada una zoonosis y una de las principales causas de pérdidas económicas en estas explotaciones. Este trabajo se enfocó en utilizar el cultivo de leucocitos de animales sin signos de abortos y la detección de anticuerpos para determinar la posible presencia de C. abortus en explotaciones de traspatio. Se obtuvieron 42 muestras de sangre periférica de ovejas de diferentes poblaciones. La detección de Chlamydia abortus se realizó mediante la tinción de Giemsa y la técnica de PCR. La detección de anticuerpos anti-C. abortus se dio mediante una técnica de ELISA comercial. Los resultados mostraron 21 muestras positivas mediante la técnica de PCR, de las cuales solo 10 fueron positivas mediante la técnica de Giemsa, mientras que 22 sueros mostraron anticuerpos anti-C. abortus. En este estudio el 38,1 % de las muestras fueron positivas a la infección por C. abortus, como se confirmó mediante PCR y serología. En conclusión, los leucocitos de sangre periférica pueden ser útiles para detectar una infección por Chlamydia spp. en explotaciones sin historial de abortos, con lo que se puede conocer la prevalencia real del aborto enzootico ovino en México.Abstract The Ewes Enzootic Abortion is a disease caused byChlamydia abortus. It is deemed a zoonosis and one of the leading causes of financial losses in this type of business. This article focuses on using the culture of leukocytes from animals without any abortion symptoms and antibody detection to determine the potential presence ofC. abortusin backyard exploitations. Forty-two samples of peripheral blood were obtained from ewes in different populations. The detection ofChlamydia abortuswas carried out by using the Giemsa dye and PCR technique. Anti-C. Abortusantibody detection was performed through a commercial ELISA technique. Results showed 21 positive samples using the PCR, and only ten were positive according to the Giemsa dye, while 22 serum samples showed anti-C. abortusantibody. In this study, 38.1% of the samples were positive for theC. abortusinfection, as verified with the PCR and serology. In conclusion, peripheral blood leukocytes can be helpful to detect an infection caused byChlamydiaspp. Animal exploitation without any previous abortion allows knowing the real prevalence of ewes’ enzootic abortion in Mexico.
       
  • Urea Levels in the Milk in silvopastoral Systems

    • Abstract: Resumen El exceso de proteína en la dieta puede generar problemas productivos y reproductivos en rumiantes. La medición de la urea en la leche permite determinar la disponibilidad ruminal de energía y proteína, y, así, hacer ajustes en la dieta de ser necesario. El objetivo de este estudio fue cuantificar la concentración de urea en la leche en un hato que pastorea sistemas silvopastoriles multiestrato en alta densidad. Se evaluó un sistema doble propósito en El Cerrito, Valle del Cauca (Colombia). Los animales estuvieron divididos en tres grupos de alimentación (praderas con guinea-leucaena-algarrobo, estrella-leucaena-algarrobo, y estrella-algarrobo, respectivamente). Se recolectaron muestras de leche en el ordeño de la mañana y la tarde de cada animal seleccionado en cada grupo, a las cuales se les determinó la concentración de urea (Ureasa/ Berthelot). La concentración de urea en la leche del ordeño de la mañana y la tarde estuvo correlacionada positivamente (r = 0,86), la concentración promedio fue de 22,7±9,4 mg/dl. Sin embargo, entre grupos de alimentación varió (p < 0,001), fue mayor en el primer muestreo (p < 0,001), y también se observó una amplia variación entre los muestreos de una misma base forrajera. Los sistemas silvopastoriles multiestrato presentan adecuado balance entre la materia orgánica fermentable y la proteína degradable a nivel ruminal.Abstract Excess of protein in the diet can lead to both productive and reproductive problems in ruminants. Measuring the urea in the milk allows determining the ruminant availability of energy and protein and, therefore, to do some adjustments to the diet whenever necessary. This study aims to quantify the urea concentration in the milk in a farm that takes care of high-density multi-layer silvopastoral systems. A system with dual purpose was evaluated in El Cerrito, Valle del Cauca (Colombia). The animals were divided into three feeding groups (prairies with guinea-leucaena-algarrobo, estrella-leucaena-algarrobo and estrella-algarrobo, respectively). Samples of milk were gathered during the morning and afternoon milking from the animal selected in each group, and then the urea concentration was determined (Urease/ Berthelot). The urea concentrations in the morning and afternoon milk were correlated positively (r = 0.86), the average concentration was 22.7+9.4 mg/dl. However, the values varied between the feeding groups (p < 0.001), it was higher in the first sample (p < 0.001). Likewise, a broad variation was observed between the samples inside the same foraging basis. Multi-layer silvopastoral systems show an appropriate balance between the fermentable organic matter and the degradable protein in the ruminants.
