Research ArticleOpen accessIn the abstractThe Effects of Dietary Whole Rice Hull as Insoluble Fiber on the Flock Uniformity of Pullets and on the Egg Performance and Intestinal Mucosa of Laying HensTossaporn Incharoen, Patchanida ManeechoteOur two experiments were intended to investigate the effects of dietary Whole Rice Hull (WRH) as insoluble fiber on the flock uniformity of pullets and the performance, egg quality and intestinal mucosa structure of laying hens. In experiment 1, a total of 1,500 chicks (4 weeks old) with the same uniform weight were randomly separated into three treatments of 500 … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 2 Nov 2013 · 8,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofortification of Food with MicroelementsKatarzyna Chojnacka, Marcin Mikulewicz, Jerzy CieplikProblem statement: Recently a particular attention was paid to the issue of microelement hunger, also termed hidden hunger. The problem was of global significance, since was related with the public health and concerns over 2 billion people. Approach: The study discusses the state of the art in the research on food biofortification as the sustainable solution to cope with micronutrient … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 28 Dec 2011 · 8,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Polymorphism Exon 9-11 at the Leptin Gene Receptor in Breeder Hens of Mazandaran Native FowlsHossein Ali Abbasi, Shahabodin Gharavysi, Rohullah AbdullahpourProblem statement: Leptin a 16 kD protein synthesized by white adipose tissue and involved in regulation of feed intake, energy balance, fertility and immune function. In order to evaluate the leptin gene receptor polymorphism, we have used a Restriction Fragment Length Polymorphism (RFLP) method. Approach: Blood samples were collected from randomly chosen 100 native fowls breeding station of Mazandaran. The … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 17 Sep 2011 · 7,700 accessesView PDFCite
Research ArticleOpen accessIn the abstractNo Damage of Dietary Dried Fermented Ginger Diet without Antibiotics on Growth Performance in Broilers Reared in Tropical AreaDuddoa Khonyoung, Koh-en Yamauchi, Tonglian Buwjoom et al.Problem statement: The experiment was carried out to determine whether the dietary Dried Fermented Ginger (DFG) has no affecting damage on broiler growth performance and can also be applicable in tropical and subtropical area using basal diets without antibiotics. Approach: Three hundred and fifty 7-d-old Arbor Acres broiler chicks were divided into one basal diet group (control) and 6 experimental … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 6 Aug 2011 · 7,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Dietary Curcumin on Rumen Fermentation, Macronutrient Digestion and Nitrogen Balance in Beef CattleT. Vorlaphim, M. Phonvisay, J. Khotsakdee et al.Abstract: Problem statement: Previous studies have shown that curcumin has antibacterial activity. It was hypothesized that the feeding of curcumin to ruminants may disturb rumen function and affect macronutrient digestibility and nitrogen utilization. Approach: In an experiment with Latin-square design, beef cattle were fed rations consisting of urea-treated rice straw and concentrates without or with 0.1 or 0.2% added curcumin. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 9,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Rumen Acid Load on Postpartum Performance and Blood Metabolic Responses in Transition Holstein CowsSadjad Danesh Mesgaran, Alireza Vakili, Alireza Heravi Moosavi, Ghasem KoolabadiProblem statement: The transition period is the most stressful time in the production cycle of a dairy cow because of depressed feed intake, endocrine and metabolic changes at parturition. The aim was to determine the effect of rumen acid load on postpartum performance and metabolic parameters in transition Holstein cows. Approach: The Acidogenicity Values (AV) of the diets were determined … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 25 May 2011 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Vitamin A on Growth Performance, Antioxidant Status and Blood Constituents in Lactating Grey GoatWeiren Yang, Ping Wang, Yuanqiang Jing et al.Problem statement: It is regarded that vitamin A protects cells from damage by radicals which are believed to contribute to certain chronic diseases and regulates immune function of animals by protection of mucosal epithelium acting as the first defense barrier. All these properties of vitamin A may be attributable to its antioxidant activity. This study was to evaluate the effects … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 7,674 accessesView PDFCite
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 · 9,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Replacement of Soybean meal by Dried Tomato Pomace on Rumen Fermentation and Nitrogen Metabolism in Beef CattleC. Yuangklang, K. Vasupen, S. Wongsuthavas et al.Problem statement: Dried tomato pomace may be considered as an alternative feedstuff in ruminant nutrition. The limited literature data that are available so far may be interpreted as indirect and suggestive evidence for diminished ruminal fermentation and bacterial synthesis after substitution of dried tomato pomace for soybean meal. Approach: Rumen-fistulated beef steers were used to address the questions whether the … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,867 accessesView PDFCite
