Research ArticleOpen accessIn the abstractDiet Modification to Reduce Fecal Excretion of Nitrogen and Phosphorus in Growing-Finishing PigsOndieki Gekara, Talesha Dokes, Renita MarshallAn experiment was conducted to determine whether brewers rice can replace all corn in diets for swine and reduce fecal excretion of Nitrogen (N) and Phosphorus (P) without compromising performance and carcass quality of growing-finishing pigs. Sixteen Yorkshire x Duroc x Hampshire crosses (BW = 77±2.5 kg) were randomly assigned to either corn/soybean meal (CSM; control) or brewers rice/soybean meal … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 3 Oct 2013 · 7,455 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuails Response to Aqueous Extract of Bush Marigold (Aspilia africana) LeafE. A. Agiang, O. O.K. Oko, G. E. Essien, Juan Eduardo Suarez RivadeneiraProblem statement: The effects of inclusion of aqueous extract of Bush marigold (Aspilia africana) leaf in quail diet were investigated. One hundred and fifty Japanese quail chicks were used in the study. Approach: In the 14-weeks feeding experiment, the birds were assigned to five treatments of; 0, 2.5, 5.0, 7.5 and 10% inclusion of aqueous extract of Bush marigold leaf. … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 24 Jan 2012 · 9,586 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Citric Acid and Microbial Phytase on Growth Performance and Carcass Characteristics of Broiler ChickensRouhollah Nourmohammadi, Seyed Mohammad Hosseini, Homayoun FarhangfarProblem statement: The aim of this study was to investigated the effects of adding citric acid and microbial phytase supplementation (Natuphos®) on growth performance and carcass characteristics of broiler chickens fed corn soybean meal base diets. Approach: The experiment included nine treatments with 10 birds in each replicate using a 3×3 factorial design for two main factors of citric acid … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 31 Dec 2010 · 8,301 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Enzyme Supplementation on Performance, Carcass characteristics, Carcass Composition and Some Blood Parameters of Broiler ChickenH. HajatiProblem statement: Endogenous enzymes of broilers cannot adequately digest nonstarch polysaccharides and subsequently the ingestion of high levels of soluble NSP leads to increased digesta viscosity and reduced nutrient digestibility and absorption. Supplementation of NSPs degrading enzymes may remove the anti nutritive effects of NSPs and release some nutrients (starch, protein) from these elements. Therefore, in a completely randomized design … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 9,654 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of Meal Feeding and Skip-A-Day Feeding With or Without Probiotics for Broiler Chickens Grown at High-Altitude to Prevent Ascites MortalityAli Saffar, Fariborz KhajaliProblem statement: Ascites is a common rapid-growth-related problem in broiler chickens grown at high altitude where the partial pressure of oxygen is low and is marginally adequate to support the growth performance and ascites-related variables. A mismatch between the growth of oxygen supplying organs and the oxygen demanding organs causes ascites in broiler chickens. In the present study, broilers were … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,701 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of L-Leucine Supplementation on Growth Performance and Carcass Characteristics of Grower-Broiler Chickens Fed Low Protein DietsE. Erwan, A. R. Alimon, A. Q. Sazili et al.Problem statement: Supplementation of broiler diets with cristalline amino acids (i.e. lysine, ethionine and threonine) may support equal broiler growth and improve overall amino acids balance and enable a reduction in CP level of diets. Approach: A trial was conducted to evaluate the effect of supplemental L-leucine in diets containing recommended levels and low crude protein (20 and 18%, respectively) … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,970 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Betaine Supplementation to Methionine Deficient Diet on Growth Performance and Carcass Characteristics of BroilersH. Sun, W.R. Yang, Z.B. Yang et al.Problem Statement: The efficacy of Methionine (Met) sparing effect of Betaine (BET) has been shown to be associated with dietary compositions, animal physiological stage and living conditions. This study was to determine the extent to which dietary Met could be replaced by BET in broiler chickens under the feeding conditions specific to Chinese poultry industry.Approach: A total of 900 day-old … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 14,162 accessesView PDF Cite
