Three experiments were conducted to determine the feeding value to broiler chicks of soybean meal (SBM) produced from high-protein (SBM-HP), low-oligosaccharide (SBM-LO), or conventional (SBM-CV) varieties of soybeans. The 3 SBM contained 54.9, 53.6, and 47.5% CP, respectively. The standardized digestibility (SDD) of amino acids (AA) in the 3 ingredients was measured using a precision-fed roost...

Study was carried out to find out the effect of L-carnitine supplementation on carcass characteristics in Venncobb broiler chicks fed with diet containing animal fat. Eighty day old commercial broiler chicks were randomly allotted to two treatment groups (T1 and T2) with four replicates of ten chicks each. The birds were fed with standard broiler chicken ration (BIS, 1992) containing 5% animal ...

This experiment was conducted to compare the effect of litter amendments by using acidifier on growth performance, carcass characteristics and welfare of commercial broiler chicks along with its economical implication during winter season (DecemberJanuary months). A total of 180, day-old (Vencobb) broiler chicks were equally and randomly assigned to two litter abatements with alum and sodium bi...

Quality control tests were applied to prove the efficacy of the Vaxxitek HVT+IBD vaccine by Identity, sterility, titration, immunosuppression, safety and potency tests. Vaxxitek HVT+IBD vaccine proved to be safe when inoculated in 1-day old chicks free from maternal derived antibodies, broiler chicks and Swiss mice with 10field dose of the vaccine. The Vaxxitek HVT+IBD vaccine did not interfere...

this research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. for that, 312 day-old male ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. diets include...

the main purpose of this study was to investigate the effects of euphorbia hirta and acidifiers supplement on resistance of broiler chickens against salmonella enteritidis infection. a total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (oa) and 3) basal diet supplemented with 7.5 g/kg e. hir...

Nutritional and environmental conditions influence broiler flock performance. Besides these factors, other less-well-understood factors, such as incubating egg characteristics, affect the embryonic life of chicks. This study demonstrated that egg storage depressed egg albumen Haugh units (HU) and chick quality; these effects of storage were greater in egg and chicks from old breeders. Absolute ...

Two balance trials were conducted to examine the response in metabolizable energy and metabolizability of both fat and amino acids to graded levels of zinc bacitracin (ZnB; Albac registered trade name of Alpharma, Oslo, Norway) in practical broiler and layer diets varying in their nutrient density. Broiler diets were supplemented with either 0, 20, or 50 mg ZnB/kg and layer diets were supplemen...

The present study was conducted to investigate whether dietary sanguinarine (Sangrovit ® , SGV) could affect growth performance, relative organ weigths, gut microbiota, serum cholesterol levels, and malondialdehyde contents of leg meat in broiler chickens. A total of 840 day-old male broiler chicks (Ross breed) was randomly placed on 28 floor pens with rice straw as a bedding and subjected to o...
