This study investigated the effects of incremental increases in acid detergent fibre (ADF) content on the nutrient digestibility and performance of South African Mutton Merino wether lambs fed low-fibre finishing diets. Four dietary treatments were formulated with similar nutritional compositions,…
The effect of increasing non-protein nitrogen content on nutrient digestibility, performance, and carcass characteristics of South African Mutton Merino wether lambs on low-fibre finishing diets containing similar degradable protein was investigated. The production and digestibility studies consisted of 60 and…
This study aimed to evaluate the effects of phytase and tannase addition in broiler diets on the growth performance and meat quality of broilers fed sorghum-based diets. Twelve experimental diets were formulated at three sorghum levels (0, 50, and 100%)…
This study reports slaughter and carcass characteristics and meat quality as a result of crossing Leghorn chickens and five different genotypes. The experiment was carried out in the Prof. Dr. Hümeyra Özgen Research and Application Farm in Selcuk University. The…
The aim of this study was to determine the effect of the addition of fig seed (FS) as a feed additive in quail rations on growth performance, carcass parameters, and antioxidant status. A total of 2000 one-day-old quail chicks were…
The objective of this experiment was to compare the effects of dietary supplementation with cooking grease recovered from rinse-trap water lines (rinse-trap grease; RTG) versus conventional supplemental fats (tallow; TL, and yellow grease; YG) on 84-d growth performance, dietary energy,…
This study focused on the effects of adding various levels of bee pollen to diets for Japanese quail (Coturnix coturnix Japonica). The response variables that were examined included their performance, carcass characteristics, meat colour, immune system, and some serum constituents.…
To evaluate the effect of a production system and feeding regimen on meat quality attributes of Naked Neck chickens, a total of 150 cockerels at 18 weeks old (1625 ± 70 g) were collected from 10 treatment groups with five…
A total of 378 unsexed Anak broiler chicks were used to assess the effects of varying energy levels and manipulation on growth, haematology, and carcass traits. The experiment was conducted in two phases. First, one-day-old chicks were randomly assigned to…
Chitosan oligosaccharide (COS) and valine (Val) supplementation will improve growth performance, carcass traits, hormonal profile and meat quality in broilers. To evaluate this hypothesis, based on a 2×4 factorial arrangement, 480 male broilers (Ross 708) were randomly placed in eight…
The aim of this research was to evaluate relationships between the PORCUS classification system and factors affecting boar taint in pork. Intact male pork carcasses (n = 176) were randomly selected in a South African commercial abattoir from three PORCUS…
The present investigation was performed to determine the impact of the dietary inclusion of ginger powder (Zingiber officinale) on the growth performance, immune response, slaughter traits, blood biochemistry and gut morphology of broiler chickens. One hundred and eighty unsexed broiler…
The influence of pre-weaning immunocastration on the growth, incidences of reaction to vaccination, serum testosterone concentration and slaughter performance of ram lambs was determined and compared to that of physically castrated lambs. Immunocastration was performed using two doses of 2…
The present study aimed at evaluating the effect of a phytogenic mixture in the diet on broiler production. A total of 400 day-old unsexed Cobb broiler chicks were randomly allotted to four treatment groups of 10 replications in a randomised…
Dried corn distillers grains with solubles (DDGS) can partially replace grains and forages in diets for ruminants. The objective of this research was to evaluate the effect of replacing grains and soybean meal with DDGS (0%, 15%, 30% and 45%)…
A 3 * 3 factorial study was used to evaluate the feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) of broilers fed on the test diets. The commercial soybean meal (SBM) was replaced by raw, full-fat…
Twenty-one non-castrated male Rambouillet lambs (21±1.44 kg body weight) were used to evaluate the effects of increasing dietary levels of Prosopis laevigata pods (PLP) in a 72 d growth performance trial. Three dietary treatments defined as PLP0 (control, 0 g…
This study was conducted to determine the effects of the addition of micronized zeolite (MZ) on the fattening performance, blood parameters, faecal ash and nitrogen levels of lambs fed concentrate feeds intensively. For two months 25 four-month-old Merino x Ile…
The present study was conducted to determine the effect of including different levels of whole cottonseed (WCS) in the finishing diet of lambs on their dry matter intake (DMI), live weight gain, feed conversion ratio (FCR, kg feed/kg gain), carcass…
Young Afrikaner crossbred steers were used for the experiment after being fed ad lib until a desired estimated carcass mass of 120 and 240 kg was reached. Carcasses were split into sides - one group of sides served as controls…
