Research ArticleOpen accessIn the keywordsPlasma Thyroid Hormone Concentrations and pH Values of Some GI-Tract Segments of Broilers Fed on Different Dietary Citric Acid and Microbial Phytase LevelsRouhollah Nourmohammadi, Seyed Mohammad Hosseini, Hamed Saraee, Alireza ArabProblem statement: An experiment was conducted to study the effect of microbial phytase supplementation and citric acid on thyroid activity, relative weight of lymphoid organs and pH values of some GI-tract segments in broiler chickens fed corn-soybean meal based diets. Approach: The data was analyzed using a Randomized Complete Block Design (RCBD) with factorial arrangement of 3×3, three levels of … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 8,316 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy on Mechanism of Ascites Syndrome of BroilersJ.L. Guo, Q.H. Zheng, Q.Q. YIN et al.Two hundred and forty male Cobb broilers were used to study the reasons of causing ascites. The results showed that cold ambient temperature could induce ascites (33.89% vs. 2.50%) and significantly increase triiodothyronine (T3), but reduce thyroxine (T4) concentrations in plasma (p<0.05). The ascitic broilers had high concentrations of aldosterone and K+, but low concentrations of T3 and T4 in … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,843 accessesView PDF Cite
