Objective: The effect of flavonoids from alfalfa on the microbial flora was determined using molecular techniques of 16S ribosome deoxyribonucleic acid (rDNA) analysis. Methods:Four primiparous Holstein heifers fitted with ruminal cannulas were used in a 4 × 4 Latin square design and fed a total mixed ration (TMR) to which alfalfa flavonoids extract (AFE) was added at the rates of 0 (A, control), 20 (B), 60 (C) or 100 (D) mg per kg of heifer body weight (BW) . Results: The number of OTUs in heifers given higher levels of flavonoid extract (C and D) was higher than for the two other treatments...

Objective: This study examines the genetic factors influencing the phenotypes (four economic traits: oleic acid (C18:1), monounsaturated fatty acids (MUFAs), carcass weight (CWT), and marbling score (MS)) of Hanwoo. Methods: To enhance the accuracy of the genetic analysis, the study proposes a new statistical model that excludes environmental factors. A statistically adjusted, analysis of covariance (ANCOVA) model of environmental and genetic factors was developed, and estimated environmental effects (covariate effects of age and effects of calving farms) were excluded from the model...

Objective: A meta-analysis was conducted to evaluate the effects of supplemental fat containing saturated free fatty acids (FA) on milk performance of Holstein dairy cows. Methods: A database was developed from 21 studies published between 1991 and 2016 that included 502 dairy cows and a total of 29-30 comparisons between dietary treatment and control without fat supplementation. Only saturated free FA (> 80% of total FA) was considered as the supplemental fat...

This study explored the physico-chemical properties of late-incubation egg amniotic fluid and a potential in ovo feed (IOF) supplement. Amniotic fluid was collected from broiler breeders (Ross 308, 51 weeks and Cobb 500, 35 weeks) on day 17 after incubation. A mixture of high-quality soy protein supplement - Hamlet Protein AviStart (HPA) was serially diluted in MilliQ water to obtain solutions ranging from 150 to 9.375 mg/ml. The mixtures were heat-treated (0, 30, 60 minutes) in a waterbath (80 oC) and then centrifuged to obtain supernatants...

Objective: Despite an increasing number of investigations into the pathophysiology of necrotic enteritis (NE) disease, etiology of NE-associated diseases, and gene expression profiling of NE-affected tissues, the microRNA (miRNA) profiles of NE-affected poultry have been poorly studied. The aim of this study was to induce NE disease in the genetically disparate Fayoumi chicken lines, and to perform non-coding RNA sequencing in the intestinal mucosal layer. Methods: NE disease was induced in the Fayoumi chicken lines (M5...

Athletic ability is an important economic trait in horses, and molecular biological research on horses' athletic abilities can lead to improvements in the animals' economic value. In a previous study, we conducted RNA sequencing analyses of the blood and muscles of horses during exercise and identified differentially expressed genes (DEGs) in response to exercise. Among them, glutamate-cysteine ligase catalytic subunit (GCLC) and glutamate-cysteine ligase modifier subunit (GCLM) genes, of which products form glutamate cysteine ligase...
