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…
The effect of increasing the non-protein nitrogen content of low-fibre finishing diets on the meat quality of South African Mutton Merino wether lambs was investigated. Four similar dietary treatments were formulated with different non-protein nitrogen contents (16.6 g/kg, 28.3 g/kg,…
It has been demonstrated that canola meal (CM) is used more efficiently than soybean meal (SBM) by lactating dairy cows. This study was conducted to determine the effects of replacing SBM with CM on production performance, blood metabolites, and ruminal…
This study determined the effect of protease supplementation in fishmeal-based diets on growth performance and meat quality of commercial broiler birds. Four hundred and thirty-two (432) day-old broiler chicks were divided into 36 experimental units of 12 chicks each. Nine…
This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens.…
To enhance smallholder beef farmers’ capacity to cope with animal feed shortages, especially dietary protein induced by climate change, it is important to evaluate the feeding value of low-cost protein sources naturally available in the environment. The aim of the…
Two experiments were carried out to determine ruminal degradability of sesame meal (SSM) and its effects on intake, digestibility, rumen parameters, chewing activity, and lamb performance when it replaced soybean meal (SBM). Degradability of dry matter (DM) and crude protein…
In an internally controlled environment, a feeding trial using 210 six-week-old female Japanese quail (189.63 ± 11.891 g liveweight) was conducted to evaluate the effect of carbohydrase-treated (endo-1.4-beta-xylanase 5600 TXU/g and endo-1.4-beta-glucanase 2500 TGU/g) canola-based diets on growth performance, haemo-biochemical…
This study was carried out to compare the performance of broilers fed diets containing only vegetable protein (VP) with birds that received an animal protein (AP) in their diets. Cobb 500 day-old male broiler chicks (n = 256) were randomly…
