Research ArticleOpen accessEvery word in the titleEffect of Autolyzed Yeast Supplementation on Productive Performance Meat Quality Visceral Organ and Cecum Bacteria of Broiler ChickensSirinapa Taechanan, Kanokporn Poungpong et al.We assessed the effects of dietary Autolyzed Yeast (AY; Saccharomyces cerevisiae) on the performance, meat quality, visceral organ weights, and cecum bacteria of broiler chickens. We utilized a total of 360 one-day-old male Ross308 chicks. We allocated the chicks to four different dietary treatments, each consisting of six duplicates. Each replica consisted of 15 chicks per pen. The study included … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 19 Sep 2024 · 5,086 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExogenous Progesterone for Offspring Sex Ratio Manipulation in Arabic Chickens (Gallus turcicus) Leading to Increasing Female Chicks ProportionIswati, Muhammad Halim Natsir, Gatot Ciptadi, Trinil SusilawatiFemale birds of egg-laying hens are more valuable than males, because males bird have no commercial value. The opportunity to manipulate offspring sex ratio in poultry has been observed in female birds; hence, female birds have heterogametic ZW chromosomes. High progesterone concentration 2-5 h before ovulation is thought to affect the segregation of female sex chromosomes as the basis for … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 17 Feb 2021 · 7,500 accessesView PDFCite
InvestigationOpen accessEvery word in the titleThe Effect of Adding Zeolite in the Feed of Chickens Cobb 500Angel Roberto Sánchez Quinche, Faviola Margarita Pindo Nagua, Oliverio Napoleón Vargas González et al.The objective of this study was to evaluate the effects of the addition of zeolite on the feeding of Cobb 500 chickens in the productive parameters. The work was carried out in an integral farm of Ecuador, adopting the standards of biosafety and animal welfare for the breeding of poultry; no vaccines or drugs were administered. 200 chickens (1-day old) … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 3 · 25 Sep 2017 · 8,661 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFermented Green Vegetable Soybean Meal Increases Dressed Carcass Meat and Bone Weight in Black-Boned Chickens (Fah Luang Chicken, Gallus gallus)Sukit Khantaprab, Buaream Maneewan, Tonglian Buwjoom et al.To use effectively waste green vegetable soyabean (edamame) and to improve the dressed carcass meat in black-boned chickens (Fah Luang chicken, Gallus gallus), fermented edamame meal was fed to black-boned chickens from 4 to 16 weeks of age. At 4 weeks of age, 20 birds (10 male and 10 female birds) were used to measure the initial weights of dressed … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 3 · 6 Sep 2017 · 8,524 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence 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 · 8,297 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExposure of Broiler Chickens to a Weak Electromagnetic Field Reduces the Impact of a Simulated, Commercial Eimeria InfectionM.A. Elmusharaf, J.J. Cuppen, H.N.A. Grooten et al.Problem statement: In a previous study, the exposure of broiler chickens to a weak Electromagnetic Field (EMF) reduced the severity of a coccidiosis infection. The birds were infected by gavage into the crop which was not representative for the field situation. Approach: The possible anticoccidial activity of EMF was investigated in broiler chickens with a simulated, commercial coccidiosis infection. There … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,276 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficacy and Characteristics of different Methods of Coccidiosis Infection in Broiler ChickensM.A. Elmusharaf, H.E. Mohamed, A. Alhaidary, A.C. BeynenProblem statement: Different methods of experimental infection of broiler chickens with Eimeria species have been described in the literature. These methods had not been compared and contrasted so as to contribute to the selection of the most appropriate model of coccidiosis in broiler chickens. Identifying such a model was important to speed up the screening of potential coccidiostatics. Approach: In … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,839 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleApplication 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 · 8,696 accessesView PDFCite
