The experiment aimed to study the effect of post-hatch early held feeding times starter supplemented with egg yolk and white on growth performance, viscera development and immune response in broiler chickens. The working hypothesis was based on the fact that better development of the gastrointestinal tract and immunity system in the first week of the chicks' life affects positively the growth p...

Feed deprivation is commonly used by the poultry industry to induce molting and stimulate multiple egg-laying cycles. However, feed deprivation has been observed experimentally to increase susceptibility of poultry to Salmonella infections. Previous studies indicated that alfalfa was efficacious in reducing Salmonella; the present investigation was designed to evaluate the efficacy of combined ...

Sixteen multiparous Holstein cows averaging 74 d in milk were used in a replicated 4 x 4 Latin square to compare the effects on animal performance of feeding whole plant silage and grain from a glyphosate-tolerant corn hybrid (event NK603), a nontransgenic control hybrid, and two commercial nontransgenic hybrids (DK647 and RX740). The grain and silage from the four corn hybrids were produced us...

Diversification of species and ingredients is essential for further developing aquaculture production. The present study aimed to evaluate the potential a blend microalgae oils poultry oil as total replacers fish in aquafeeds, fast-growing diversification, that was shown require high dietary n-3 LC-PUFA levels. For purpose, meagre juveniles ( <math xmlns="http://www.w3.org/1998/Math/MathML" id=...

A study was conducted to evaluate the effects of varying drying temperature (Fresh, 85, 95 or 105 degrees C) on the nutritive value of maize and response of broiler chickens to diets based on such grain, and supplemented with a microbial enzyme (Avizyme 1500). The chemical composition of the grain was affected by drying temperature. Starch and amylopectin contents were increased while there was...

Western honey bee (Apis mellifera L.) populations face declines commonly attributed to pesticide, pathogen, and parasite stress. One way beekeepers combat these stressors is by providing supplemental protein diets to honey bee colonies to ensure adequate colony nutrition. However Nosema spp., a microsporidian parasite of the honey bee, is thought to be associated closely with a colony's nutriti...

High fiber and nonstarch polysaccharide-based poultry diets have received more interest recently for retaining or promoting beneficial gastrointestinal microbial populations. The objective of this study was to investigate and compare the in vitro potential fermentability of high-fiber feed substrates (HFFS) by laying hen cecal microflora. Feed sources examined included soybean meal, soybean hul...

this experiment was conducted to evaluate the effects of using rice bran, combo multi-enzyme and probiotic (protexin) in diet on performance, egg traits, biochemical parameters and blood cells of commercial laying hens. this experiment carried out using 384 hi-line (w36) laying hens in a completely randomized design as factorial (2×2×2) arrangement with two levels of rice bran (0 and 10%), two ...

Many dog owners see homemade diets as a way of increasing the bond with their pets, even though they may not have the convenience of commercial diets. Modifications of ingredients, quality and proportion might change the nutritional composition of the diet, generating nutritional imbalances. The present study evaluated how dog owners use and adhere to homemade diets prescribed by veterinary nut...
