: The Silkie chicken (Gallus gallus domesticus Brisson) is one of domestic chicken breeds with commercial rearing and breeding potentials for egg production. Prolactin (PRL) and dopamine D2 receptor (DRD2) are potential genes associated with reproductive traits in chickens. This study was conducted to analyze the association of PRL and DRD2 insertion/deletion (Indel) polymorphisms with chicken reproductive traits in Silkie chickens. A total of 380 hens from 16-40 weeks of age were used, with each one being placed in a separate cage. DNA isolation was performed...

This study evaluated the contribution of fermented pearl millet [Pennisetum glaucum (L) R. Br.,] on growth performance, physiological responses, gut morphology, and microbial composition in the caeca. One hundred and eighty day-old Arbor Acre broiler chicks were assigned into five groups and were fed starter (d 0 to 21) and finisher (d 22 to 42) diets. Test diets included a control composed of maize-soybean meal (0%); a similar diet with maize replaced with fermented pearl millet (FPM) at 25, 50, 75, and 100%. Results showed that there was no significant improvement in weight gain and feed conversion ratio although more feed was consumed (P = 0.035) as FPM increased in the diet. Carcass yield increased linearly (P = 0.05) at d 42. Bursa of Fabricius quadratically increased (P = 0.02) in weight particularly at 25% and 50% FPM levels at d 21. ...

This study aimed to evaluate carcass characteristics and meat quality of cross-bred (Brahman × Lai Sind, BL) bulls and cross-bred (Red Angus × Lai Sind, AL) bulls. A total of 30 bulls, 15 head/crossbred genotype were fattened for 90 days before slaughtering at 24 months of age. Carcass traits and meat quality were accordingly measured in 30 slaughtered animals. Results showed that the slaughter weight, carcass weight, carcass dressing, meat percentage, loin muscle area were higher for AL bulls than for BL bulls (p

Antioxidants are molecular compounds that can give their electron structure to free radical molecules without disturbing them and can break the chain of free radical compounds. Antioxidants that can be used include enzymatic and non-enzymatic antioxidants. Supplementation of antioxidants into maturation mediums or cu...

Abstract: Previous issue Next issue ArchiveVolume 12 (5); September 30, 2022Research PaperTrends estimation in annual numbers of merino sheep and wool production in South Africa, from 1980 to 2017Bila L, Tyasi ThL and Khetsha ZP.

The economic important value of wool in South Africa is influenced by many characteristics that meet processor capacities and consumers’ preference. The study was conducted to characterize the trends of annual Merino sheep numbers, wool sales and wool auction price in South Africa, from 1980 to 2017. The data from year 1980 to 2017 was retrieved from the abstract of agricultural statistics which was published by the Department of Agriculture, Land Reform and Rural Development (DLRRD) in 2020 was used. Trends were analysed using the differences and percentage change between numbers of years in each independent variable (annual number of Merino sheep, wool sales and wool auction price). The findings indicated that there was a trend in annual number of Merino sheep, wool sales and wool auction prices. In annual numbers of Merino sheep, the highest decr...

Natural polymers are non-toxic, affordable, and abundantly accessible; hence they're often used in edible coatings. Covering vegetables with edible coatings that include antimicrobials, browning inhibitors, and nutraceuticals is a unique way to increase their nutritional value. Natural polymers are non-toxic, affordable, and abundantly accessible; hence they're often used in edible coatings. Covering vegetables with edible coatings that include antimicrobials, browning inhibitors, and nutraceuticals is a unique way to increase their nutritional value. Most edible coatings employ non-toxic, inexpensive, readily accessible natural polymers. Using biodegradable synthetic polymers and liquid and solid lipids, nano systems may be built at room temperature. To minimise food ...

DOI : https://dx.doi.org/10.51227/ojafr.2022.14
This review was designed to spotlight on avian bordetellosis regarding the bacterium pathogenesis, susceptibility, transmission, pathology, laboratory diagnosis, and prevention and control measures. Bordetellosis (moreover called turkey coryza) is a contagious bacterial upper respiratory disease of poultry, especially turkey poults. The disease is characterized by high morbidity and low mortality with terrible economic losses for turkeys industry. Bordetellosis is caused by Bordetella avium (B. avium) bacterium which colonizes an...
