      Pages: 167 - 173
      Abstract: This study aimed to determine the performance of eggs and blood cholesterol of laying hens fed with fragrant pandan leaf flour (Pandanus amarylifolius Roxb). A total of 200 laying hens were used in the study, with 5 treatments and 5 replications, each filled with 8 chickens. The research design used was completely randomized (CRD), and further analysis was conducted using Duncan's Multiple Range Test. Treatments given fragrant pandan flour were 0%, 1%, 2%, 3%, and 4%. This research was conducted for 8 weeks. Parameters included: ration consumption (g/head), ration conversion, egg weight (g), Hen Day Production (%), blood cholesterol (mg/ml), blood HDL (mg/dl) and blood LDL (mg/dl). Results showed that the use of fragrant pandan leaf flour up to 4% gave a very significant effect (P < 0.01) on conversion, hen day egg weight production, blood cholesterol, blood HDL, and blood LDL, but not significantly different (P > 0.05) on ration consumption. The study concluded that using up to 4% of fragrant pandan leaf flour increases egg production and reduces ration conversion, blood cholesterol, blood HDL, and blood LDL of laying hens and ration consumption and does not cause negative effects on the laying hens.

      Abstract: The study evaluated the effect of feeding red dragon fruit (Hylocereus polyrhizus) peel meal on internal organs, ileal coliform counts, and growth performances in broiler chicken. A total of 96 birds of unsexed one-day-old broiler (Ross strain) were randomly divided into four dietary treatments and six replications with four birds each. The dietary treatments were basal diet as a control diet (DPM0), basal diet added with 0.5% red dragon fruit peel meal (DPM1), and 1% red dragon fruit peel meal (DPM2), and 1.5% red dragon fruit peel meal (DPM3). The cecum and carcass percentage in the broiler was significantly enhanced (p<0.05). At the same time, the coliform total in the ileum and abdominal fat were significantly decreased (p<0.05) with the increasing level of feeding dragon fruit peel meal. The difference in other internal organs' feed intake and body weight gain during the treatments were insignificant (p>0.05) after five weeks of feeding. In conclusion, the red dragon fruit peel meal effectively improves growth performance and gut health by increasing carcass percentage and decreasing abdominal fat production and ileal coliform count in broiler chickens.

      Pages: 183 - 191
      Abstract: The purpose of this study was to determine and evaluate the use of date seed flour in feed on the small intestine characteristics of broilers. This study used 200 Day Old Chick (DOC) broilers with type MB 202. This study used a field experiment method with a Completely Randomized Design (CRD) consisting of 5 treatments and 4 replications. The treatments used were P0: basal feed without the use of date seed flour (DSF), P1: basal feed using 2.5% DSF, P2: basal feed using 5% DSF, P3: basal feed using 7.5% DSF, P4: basal feed using 10% DSF. The variables measured in this study were the number of villi, villi height, villi surface area, crypt depth, digesta pH, and digesta viscosity. The data obtained during the study were processed using Microsoft Excel software and analyzed using analysis of variance (ANOVA) and continued with Duncan's Multiple Range Test if the results obtained were significantly different (P<0.05) or very significantly different (P< 0.01). This study gave results that were not significantly different (P>0.05) on the number of villi, villi height, villi surface area, crypt depth, and digesta pH. However, this study was able to give very significantly different results (P<0.01) in digesta viscosity. The conclusion of this study is the use of date seed flour in feed up to 10% was able to give good results on the number of villi, villi height, villi surface area, crypt depth, and digesta pH of the small intestine of broilers, but it has not been able to give good results on the digesta viscosity of the small intestine of broilers.

  • The role of the digitized milk collection point in increasing milk quality
           and income of smallholder dairy farmers in Pangalengan-Bandung

    • Authors: Erwidodo Erwidodo, Tri Bastuti Purwantini, Iwan Setiajie Anugrah, Ening Ariningsih, Handewi Purwati Saliem, Erma Suryani
      Pages: 192 - 201
      Abstract: The low quality of fresh milk has become one of the main constraints smallholder dairy farmers face in almost all developing countries, including Indonesia. The low quality of fresh milk has resulted in lower prices received by farmers. It can even result in the rejection of milk by milk processors, which is detrimental to smallholder farmers. This paper aims to analyze the impact of automated and digitized milk collection points (AD-MCPs) on the quality of fresh milk, the price of milk, and smallholder dairy farmers' income in Pangalengan, Bandung, West Java. The data and information of 300 households are part of the baseline survey of 600 smallholder dairy farmers in four districts of West Java between July and September 2017. The results show that AD-MCP facilities have successfully encouraged smallholder dairy farmers to adopt and implement improved management practices to increase dairy cows' productivity and fresh milk quality, resulting in increased prices and farm income.    Therefore, the government needs to endorse, facilitate, and accelerate the development of AD-MCPs to increase domestic fresh milk production, quality of fresh milk, and dairy farmers' income. AD-MCP development is implemented through a partnership between dairy farmers, cooperatives, and milk processors.

    • Authors: Sucik Maylinda, VM. A. Nurgiartingsih, N. Isnaeni, S. B. Siswijono, A. Furqon
      Pages: 202 - 209
      Abstract: The aims of present study was to evaluate the qualitative and quantitative characteristics of imported sheep such as Texel crossed and Dorper sheep, compared with local sheep (Fat Tail Sheep/FTS) in almost the same region, namely Pujon and Karangkates. This research was a field research with case study methods and research materials as many as 39 for Texel crossed sheep, 19 for Dorper sheep and 37 for FTS. The age of the sheep ranges from 1.5 to 3 years (some have their first calf). Qualitative data were analyzed by Population Genetics Analysis and quantitative data were analyzed by One-Way Design Anova using Minitab software version 13. The results showed that: (1) Qualitative traits in Texel crossed , Dorper and FTS sheep showed that some traits underwent fixation where one of the traits was fixed. One allele in Texel crossed and Dorper sheep has disappeared and no longer exist in its origin place such as horned and hornless traits, white body color and black head, erect ears, while in FTS sheep it is still polymorphic, especially in the hornless and drooping ears in FTS. The white color on the FTS seems to have been fixed, because the dominant gene frequency/ p = 1 and the recessive gene frequency/ q = 0. (2) The quantitative traits such as body weight, in which the body weights of the Texel crossed , Dorper and FTS breed were different in the study, and the Dorper sheep the highest body weights, while the body weights of Texel crossed and FTS sheep were almost the same. Dorper sheep had the highest head index, and Texel crossed sheep and FTS sheep had the same head index. It was concluded that Texel crossed and Dorper sheep had many fixed qualitative characteristics such as horns, erect and drooping ears, white body color and black head in FTS sheep were quite polymorphic in horns and erect and drooping ears. The best growth of Dorper sheep because Dorper sheep was originated from a crossing between Dorset and Black Persian sheep.

      Abstract: This research aims to determine the perception of farmers on the performance of Extensionist in the agroecosystems of pasture, agriculture, plantation, and forest at Timor Island, so that it can be information for improving the performance of extension workers who have an impact on repair the welfare of farmers. This research was conducted from January to December 2018. The research location was determined purposively representing the agroecosystem of pasture, agriculture, plantation and forest. The determination of respondents are 5-10% of the number of farmers in each agroecosystem that has > 10 Bali cattle. Data collection methods are done through observation, interviews, and documentation. Data processing method uses a Likert Scale, then analyzed decriptivelly. Indicators to measure the performance of livestock Extensionist based on Extensionist profile, materials and methods, procurement of activities, availability of teaching aids, and intensity of extension activities. The results showed that farmers' perceptions at agroecosystems of pasture, agriculture, plantation, and forest toward livestock extensionist in the category agreed that the existence of extensionist could be said well in aspects of Extensionist profile, materials and methods, and procurement of activities. This condition explains that Extensionist in carrying out his duties and functions in the field in accordance with existing standards, namely as a mediator, motivator, educator, communicator, facilitator, and assistance/visits. Nevertheless, it is very necessary to improve and repair the role of Extensionist related to competence so that it can influence farmers to be more productive in developing Bali cattle farming business them. Then Bali cattle farmers in the pasture agroecosystem with the highest value of the use of teaching aids by extensionist were 2 kinds (44,0%). Then the average farmers in agricultural agroecosystems with the highest value of the use of teaching aids by extensionist is 1 kind (40,2%). Next, the average of farmers in plantation agroecosystems with the highest value of using teaching aids by Extensionist are > 2 kinds (47,9%). While the average farmers in forest agroecosystems with the highest value of the use of teaching aids by Extensionist is 1 kind (>77,3%). While the intensity of extension activities during the past year shows that the average farmers in agroecosystems of pasture (70,7%), agriculture (59,8%), plantations (50,0%), and forests (68,2%) said more from 1 time.

      Pages: 241 - 252
      Abstract: This study aims to describe changes in the agro-industrial activities of salted eggs in Brebes Regency during the Covid-19 pandemic, both in marketing and agro-industrial processes. This research was conducted from January to April 2021. A total of 135 active salted egg agroindustries located in 12 sub-districts of 17 subdistricts in Brebes Regency were applied in this study. The research sample was 50 industries determined by purposive random sampling, namely districts with the most significant number of salted egg agroindustries (Brebes, Bulakamba, and Warnasari Regencies). Respondents are the owners of salted egg agroindustries who were selected as samples. Primary data (marketing distribution of salted eggs and salted egg processing technology) were collected by interview using a questionnaire and observation. Secondary data were collected by recording related documents from the government and the Central Bureau of Statistics of Brebes Regency. Data on the distribution of egg processing technology was analyzed descriptively. During the Covid-19 pandemic, producers had difficulty obtaining raw materials during a pandemic which triggered a 59% decline in salted egg production followed by a decrease in demand. Changes in salting salted eggs did not occur during the Covid-19 pandemic despite a decline in production. Salted egg producers do not reduce the quality of the salting method. As many as 30% of salted egg producers produce a combination of original, grilled, and baked flavors.

  • The effectiveness of cassava leaf meal (Manihot esculenta Crantz) in feed
           with enzymes supplementation on Broiler digestive organs

    • Authors: Ririn Angriani, Widya Hermana, Muhammad Ridla
      Pages: 264 - 273
      Abstract: This research aimed to evaluate the effect of cassava leaf meal with enzyme supplementation in feed on the digestive organs of the broiler. The research used a completely randomized factorial design on 48 Cobb-strain broilers distributed into two observation factors and four replications (consisting of 2 samples). The observation factor is factor 1 is the addition of cassava leaf meal (0%; 1.5%; and 3.0%), and the second factor is the addition of non-starch polysaccharides and protease enzymes with each dose of 250 g/ton feed (with and without enzymes). The variables analyzed were the relative weight of the digestive organs, the relative weight of the parts of the small intestine, and the relative length of the parts of the small intestine. The data obtained were analyzed by analysis of variance (ANOVA), and if the results indicated significantly different, then the posthoc test was conducted. The results showed that the addition of cassava leaf meal could increase the relative weight of the gizzard significantly (p<0.05). The addition of enzymes can significantly decrease the relative weight of the gizzard, small intestine, pancreas, ileum, and the relative length of the duodenum and ileum (p<0.05). The use of cassava leaf meal in the feed up to 3.0% does not interfere with digestive organs. There was no interaction between cassava leaf meal and enzymes on size response of digestibility broiler organ. The addition of enzymes can offset the detrimental effects caused by the use of cassava leaf meals in feed.

  • Assessment of heat stress in dairy cows related to physiological responses

    • Authors: Kartika Budi Utami, Budi Purwo Widiarso
      Pages: 283 - 293
      Abstract: Climate change will continue to occur in the years to come and threaten dairy cows. As a result of climate change, various risks can change due to changing ecological conditions in various places on earth. The study aimed to assess heat stress in dairy cows (calf, heifer, lactating, and dry cow). The heat stress assessment method uses the equation presented by the temperature-humidity index (THI). Heart rate, respiratory rate, and rectal temperature are physiological parameters to determine heat stress. The data collection of cattle's temperature, humidity, and physiological parameters was carried out simultaneously. Data analysis used one-way ANOVA, followed by Tukey's further test. The results of the heat stress assessment showed that the THI values reached 82.8 and 78.2 in the afternoon and evening, causing the calves, lactating cow, and dry cow to be exposed to heat stress. The rectal temperature of the calf increased by 39.10C, the heart rate and respiration rate of lactating cows increased by 66.5-69.2 times/minute and 51.7 times/minute, and the respiration rate of dry cows increased by 49.2 times/minute. Efforts are needed to control heat stress in dairy cows at all age phases so that dairy cows are in comfortable environmental conditions.

      Pages: 294 - 304
      Abstract: A study was carried out to determine the effect of peppermint (Mentha piperita) leaves meal on ammonia production, dry matter excreta, egg production, and the quality of laying hens. A total of 80 laying hens of Lohmann Strain aged 20 weeks old were used as experimental animals. The birds were allocated in individual battery pens. The 20-week-old laying hens were vaccinated for New Castle diseases protection by using Vaksimune®ND B1on day 5 after arrival. The hens were kept for 8 weeks and fed four experimental diets. The diets used were basal diet (BSL), basal + 1% peppermint leaves meal (PLM) (BSL+1PLM), basal + 2% PLM (BSL+2PLM) and basal + 3% PLM (BSL + 3PLM). Feed and drinking water were present at all times. Parameters measured were ammonia concentration, dry matter excreta, hen day production, total egg mass, feed intake, FCR, dry matter digestibility, and quality of 14-days-stored eggs. A completely randomized design with 4 experimental diets and 5 replications was used. Data collected from this study were analyzed by using analysis of variance and tested with the Tukey test. The addition of peppermint leaf meal reduced ammonia production and increases dry matter excreta, total egg mass production, and dry matter digestibility. The Haugh unit, yolk height, and albumen height were improved when the eggs were kept for 14 days at room temperature. The addition of peppermint leaves meal decreased the mass loss of 14 days-stored eggs. In conclusion, supplementation of diets with peppermint leaf meal decreased ammonia concentration and watery excreta and increased the quality of eggs stored for 14 days at room temperature.
