Feed intake models seldom take breed differences into account. This study investigated various approaches to describing and predicting the feed intake of certain breeds (Dohne Merino, Dormer, Dorper, Meatmaster, Merino, South African Mutton Merino (SAMM) and White Dorper). On weaning…
This study was conducted to evaluate the effects of ferulic acid (FA) on the growth, nutrient digestibility, digestive enzyme activities, immunity and antioxidant status of broilers. Ninety-six one-day-old male Arbor Acres broilers were randomly divided into two groups with six…
The study was designed to compare low and high levels of protein, namely 90 and 147 g/kg of dietary dry matter, and to evaluate the effect of concentrate proportions on the in situ digestion kinetics of neutral detergent fibre in…
Agroecological dairy production systems are gaining attention worldwide. However, few studies have compared the quality of bovine milk produced in these systems with that produced in conventional dairy production systems. In view of the different farming practices, it was expected…
In an experiment, the efficacy of Tragopogon graminifolius (TG) plant powder as a medicinal supplement for laying hens was investigated. A total of 192 Hy-line (W36) hens that had been laying for 52 to 63 weeks, were used. They were…
Effects of protected sodium butyrate (PSB) in broiler diets with reduced metabolizable energy (ME) content on production performance, intestinal histomorphometry and nutrient metabolizability were evaluated in two experiments. In one experiment, 384 one-day-old male chicks with an average weight of…
An understanding of genetic information and relationships among traits is required for an improvement programme to be successful. Therefore, this study aims to estimate certain (co)variance components for bodyweights Mecheri sheep collected at various ages. The data consisted of 2…
The study investigated the effect of crossbreeding Charolais bulls with Nguni cows on carcass and lean yield and meat quality characteristics. The intact Charolais bulls (n=10) served as control group against the Charolais x Nguni (n=10). The Nguni dam proved…
This study was conducted to determine the slaughter, carcass, and egg quality characteristics of domestic geese reared in Uşak, Afyon, and Kütahya provinces of the Aegean region. Ninety-six eggs were obtained from 38¬- to 44-week-old geese from four locations in…
The digestible lysine requirements for fattening pigs have not been established clearly. The objective of this trial was to determine a level of protected lysine in pig diets that was adequate for growth performance, carcass characteristics, and plasma urea nitrogen…
In this study bacterial populations were identified in the rumen of zebu cattle fed various diets and classified taxonomically with metagenomic sequencing of the 16S rRNA gene. Twenty-four (24) heifers were used in a completely randomized experimental design to test…
The objective of the study was to evaluate the effects of feeding live earthworms (Eisenia foetida) (Savigny, 1826) (Musyoka et al., 2020) and tilapia (Oreochromis mossambicus) (Peters, 1852) (Russell et al., 2012) on the growth rate of African sharptooth catfish…
Discrepancies in sensitivity and specificities of tests (enzyme-linked immunoassay (ELISA) and tuberculin skin test (TST)), prevalence, and potential risk factors associated with Mycobacterium avium subsp. paratuberculosis (MAP) of bovine were hypothesized to affect its control. Keeping PCR as the gold…
The objective of this study was to investigate differences between four strains of chickens on laying hen productivity and egg quality under acute heat stress (AHS). The study consisted of 44 hens from each of the Fayoumi (FY), Golden Sabahia…
The goal of this study was to determine effects of trehalose (T) and Trolox (TX) additives on post-thaw viability of canine sperm after freezing. The sperm-rich portions of ejaculates obtained from 15 dogs were divided into three aliquots, which were…
Improved understanding of the microbial populations during intensive feeding of feedlot cattle holds potential for optimizing production efficiency. Ionophores are used to increase the production and efficiency of ruminants and are commonly used in South African feedlots. Bonsmara bull calves…
The aim of this study was to examine the effects of replacing soybean meal (SBM) with increasing levels (0%, 33%, 67%, and 100%) of sugarcane yeast and urea on the intake, performance, and feeding behaviour of buffalo heifers. Twenty Murrah…
The goal of this study was to assess the qualitative and sensorial characteristics of beef and pork sun-dried meat (SDM) with different salt (NaCl) levels (6%, 8% and 10%) and curing times (30 and 40 h). Samples from the beef…
Usefulness of red grape pomace (GP) by-product in ruminant rations is restricted by its high fibre content. Pre-treatment with exogenous carbohydrases may partly resolve this problem. Therefore, the effects of various levels of an exogenous fibrolytic enzyme mixture (Viscozyme® L)…
The aim of this study was to determine the prevalence of cattle infected by Hypoderma, a parasite that causes great economic losses in the world, especially in the Ardahan region. A total of 31 095 cattle skins were randomly selected…
