The higher bioavailability, lower toxicity, and lower potential environmental risks of zinc oxide nanoparticles (ZnO NPs) compared to traditional sources of zinc (Zn) encouraged researchers to use it in animal diets. The current study aimed to investigate the effects of dietary low ZnO NPs levels supplementation on the meat yield of Shami goats usi...

This study aimed to evaluate the effect of four combinations of dietary linseed oil and lysine mixtures on performance, fatty and amino acid profiles, oxidative stress biomarkers, cell energy and meat quality parameters of broiler chickens. One hundred and sixty broiler chicks were allocated into four groups. Birds of groups 1-4 were fed diets cont...

Three hundred and sixty quails were divided into six groups to evaluate the effect of dietary betaine on profiles of proteins and lipids, bioenergetics, peroxidation and quality of meat of Japanese quail fed diets containing three levels of metabolizable energy (ME) viz. optimum (2900 kcal ME/kg), restricted (2800 kcal ME/kg) and low (2700 kcal ME/...

This study aimed to evaluate the effect of dietary linseed oil, sunflower oil, and their supplementation with Amphora coffeaeformis (AC) on growth performance, carcase characteristics, fatty and amino acid profiles, oxidative stability, and meat quality of broiler chickens. One hundred and eighty day-old broiler chicks were divided into four groups...

Background: The use of zinc oxide in the form of nanoparticles (ZnO-NPs) is of great benefit due to its potent effectiveness and higher bioavailability compared to zinc oxide. This study aimed to investigate the impact of dietary inclusion of different doses of ZnO-NPs on selected serum biomarkers, lipid peroxidation and tissue gene expression of...

The study used 96 broiler chickens to evaluate the impact of three species of microalgae on performance, profiles of fatty and amino acids, antioxidants, and meat quality of breast muscles. Birds were divided into four groups (24 birds/each) with 4 replicates (6 birds each). Birds in the first group were fed basal diet and served as a control (C)....

Understanding ruminal biohydrogenation of linoleic and linolenic acid is important in relation to physiological responses in the animal and the fatty acid profile of ruminant meat and milk. Alterations in ruminal biohydrogenation pathways leading to an increased formation of trans-10-18:1 are known to occur with high-concentrate diets and marine su...

The effects of adding essential oils (EO) at different levels (125, 250, 500 mg/l) on rumen fermentation and biohydrogenation were examined in a rumen batch culture study. Treatments were: control without EO (CON), control with anise oil (ANO), cedar wood oil (CWO), cinnamon oil (CNO), eucalyptus oil (EUO), and tea tree oil (TEO). Essential oils, e...

A B S T R A C T The main objectives of this study were the partial substitution of corn and soybean meal with dried distiller's grains with solubles (DDGS) and Allzyme SSF® supplementation in growing-finishing rabbit diets studying the effect of these diets on rabbit's performance. The feeding trial was performed on 72 rabbits of both sexes, equall...

A B S T R A C T The main objectives of this study were to partially substitute corn and soybean meal with dried distiller's grains with solubles (DDGS) and to supply Allzyme SSF® in growing-finishing rabbit diet, investigating the influence of these diets on rabbit's meat quality. Seventy two rabbits of both sexes were randomly assigned in a feedin...
