Growing lambs were evaluated for the effect of increasing dietary levels of beef tallow (BT) on performance, rumen fermentation, and carcass and meat characteristics. Twenty-one 5-month-old male Rambouillet lambs were assigned randomly to one of three diets with 0, 20,…
This experiment was conducted to determine the interaction effects that resulted from supplementation of low-protein diets with leucine (Leu), valine (Val), and glycine-glutamic acid (Gly-Glu) on growing broiler chicks from 11 to 24 days old. Two levels of digestible Leu…
Sow longevity (sow productive lifetime) plays an important role in economically efficient piglet production. Direct selection for sow longevity is not commonly practiced in any pig-breeding program. In recent years, an increased number of peer reviewed articles addressing the economic…
Objectives of the experiment were to determine effects of dietary hay concentration in a dry total mixed ration and its carryover effects on intake, growth performance, faecal score, and feed efficiency of weaned dairy calves. Eighteen Friesian × Jersey weaned…
The aim of this research was to assess genetic diversity of Korean-Holstein, Korean Hanwoo, and Ugandan-Holstein dairy cattle. DNA was extracted from either blood or hair of Korean-Holstein (n=74), Korean-Hanwoo (n=75) and Ugandan-Holstein (N=77) using AccuPrep® PCR purification kit. The…
In most extensive beef production systems in South Africa, calves are weaned at specific dates. This implies that cows that calve late in the season wean younger and lighter calves. In the current study, Bonsmara cows were mated naturally after…
The aim of this study was to determine the chemical, fermentation, and microbiological properties of alfalfa silages that were augmented with lavender (Lavandula angustifolia) and to appraise their in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), and net energy…
This study evaluated effects of microbial inoculation on fermentation, aerobic stability and ruminal dry matter (DM) degradation of silage produced from Avocado (Persia Americana) pulp (AP). The AP, 800 g/kg fresh matter (FM) was mixed with 150 g grape pumice…
Objectives of this study were to evaluate effects of grazing tropical forage species and level of supplementation with grain on characteristics of lamb meat. Ninety-day-old lambs (n = 36) (22.54 ± 2.72 kg) were randomly assigned to a 2 x…
Bromide (Br-) concentrations (mg/L) in groundwater range from no observed adverse effect levels (NOAEL), which is considered safe, and increase to constituent of concern (COC) when the concentrations approach the recommended maximum levels for safety, and to potentially hazardous chemical…
Sound claws are essential for beef cattle, given the marked influence they have on functional longevity and subsequent performance. The aim of this study was to evaluate morphological and physiological claw characteristics of Bonsmara SA beef cattle in the major…
The aim of this experiment was to evaluate the effects of replacing distillers dried grains with solubles (DDGS) with fermented DDGS (FDDGS) on meat quality and serum amino acid profiles in Chinese yellow broilers. Forty-eight 42-day-old male Chinese yellow broilers…
A study was conducted to determine the effects of dietary hydroalcoholic willow bark extract powder (HWE) supplemented to broilers (14–42 days old) that were exposed to heat stress, on the performance, serum biochemical parameters, liver oxidative status and caecal microflora…
This study investigated the effects of incorporating different protein sources (oil seed cakes versus Leucaena leucocephala hay) in a total mixed ration (TMR) on intake, digestibility, growth and carcass meat quality of Saanen goats. Sixteen Saanen male goats were allocated…
The aim of this study was to evaluate intake, performance, carcass characteristics and meat quality of lambs fed finishing diets containing 0%, 7.5% and 15% safflower seeds (Carthamus tinctorius) as a replacement for corn and soybean meal. Thirty-six male lambs…
This study was conducted to determine the effects on performance, egg quality parameters and some serum profiles of vitamin E, thyme and rosemary extracts that were added to laying hen feeds. One hundred twelve 48-week-old Bovans-genotype white laying hens were…
This study aimed to evaluate the influences of electrical stimulation (ES), age at slaughter, and breed type on muscle pH, the decline in carcass temperature, and meat quality attributes of Sudanese indigenous Baggara cattle. Eighty Baggara bulls, representative of Nyalawi…
The effects of feeding various dietary protein levels on the fattening of male Beetal goats were investigated. Twenty-seven bucks (initial bodyweight 35 ± 0.5 kg) between 12 and 16 months old were randomly assigned to one of three treatments The…
This study was designed to investigate the effects of adding black cumin (Nigella sativa L.) seed (BCS) oil to diets for broiler chickens on their performance and the meat fatty acid profile of the meat. Broiler chicks were assigned to…
This study was conducted to evaluate the effects of different sources of zinc (Zn) on feed intake, milk yield, milk composition, and blood metabolites. Twenty-four dairy cows were randomly allocated to one of four treatments in a randomized complete block…
