Amino acid requirements in horses

Asian-Australas J Anim Sci 2020 05 12;33(5):679-695. Epub 2020 Mar 12.

Department of Animal and Food Sciences, University of Kentucky, Lexington, KY 40546, USA.

Evaluating amino acid requirements, specifically threonine requirements, in horses will enable better feed formulation and result in economic production, improved animal health, and reduced environmental pollution. However, the current knowledge of protein and amino acid requirements in horses is still limited. Because horses have a unique digestive system and consume a variety of feed ingredients, their protein digestibility may be affected than other species by different feed composition, and thus amino acid requirements are susceptible to vary between situations.

Association of the thyroid hormone responsive spot 14 alpha gene with growth-related traits in Korean native chicken.

Asian-Australas J Anim Sci 2020 Feb 25. Epub 2020 Feb 25.

Department of Animal and Dairy Science, College of Agriculture and Life Sciences, Chungnam National University, Daejeon 34134, Korea.

Objective: Thyroid hormone responsive spot 14 alpha (THRSP) has been used to investigate the regulation of de novo lipogenesis because the variation of THRSP mRNA content in the tissue affects directly the ability of that tissue to synthetize lipids. Also, this gene responds to thyroid hormone stimulation and high level of carbohydrate feeding or insulin-injection. This study was carried out to investigate variations within THRSP and their effects on body and carcass weights in Korean native chicken (KNC). Read More

College of Animal Science and Technology, Jiangxi Agricultural University, Nanchang 330045, China.

Objective: To explore the molecular mechanisms of fatty liver hemorrhagic syndrome (FLHS) in laying hens, an experiment was conducted to reveal the differences in histopathological observation and gene expression between FLHS group and normal group.

Methods: We compared the histopathological difference using hematoxylin and eosin staining and proceeded with RNA sequencing of adipose tissue to search differentially expressed genes and enriched biological processes and pathways. Then we validated the mRNA expression levels by real-time PCR and quantified protein levels in the circulation by enzyme-linked immunosorbent assay (ELISA). Read More

Association of UDP-galactose-4-epimerase (GALE) with milk protein concentration in the Chinese Holstein population.

Asian-Australas J Anim Sci 2020 Feb 25. Epub 2020 Feb 25.

Mammalian NutriPhysioGenomics, Department of Animal Sciences and Division of Nutritional Sciences, University of Illinois, Urbana, Illinois 61801, United States.

Objective: An initial RNA-Sequencing study revealed that UDP-galactose-4-epimerase (GALE) was one of the most promising candidates for milk protein concentration in Chinese Holstein cattle. This enzyme catalyzes the interconversion of UDP-galactose and UDP-glucose, an important step in galactose catabolism. To further validate the genetic effect of GALE on milk protein traits, genetic variations were identified and genotypes-phenotypes associations were performed. Read More

Asian-Australas J Anim Sci 2020 Feb 25. Epub 2020 Feb 25.

Hokkaido University, Sapporo, Japan.

Objective: Soy sauce oil, a byproduct of whole soybean processing by the soy sauce industry, was evaluated as a source of linoleic acid for dairy cows for the purpose of manipulating the composition of milk.

Methods: Eight dairy Holstein cows fitted with rumen cannulas were used for ruminal administration of soy sauce oil for a 28-day period using a 4 x 4 Latin square study design with 4 doses (0, 200, 400 and 600 g soy sauce oil/d).

Results: Although dry matter intake and milk yield were not affected by soy sauce oil administration, ruminal concentrations of total volatile fatty acids and acetate were decreased, specifically at 600 g/d administration. Read More
