The objectives of this study were to estimate covariance functions for genetic and permanent environmental effects and obtaining genetic parameters of 305-day milk yield over seven parities. Data including 60,279 total 305-day milk yield of 17,309 Iranian Holstein dairy cows in 7 parities calved between 20 to 140 months between 2004 and 2011. Residual variances were modeled by homogeneous and step functions with 7 and 10 classes. The results showed that a third order polynomial for additive genetic and permanent environmental effects plus a step function with 10 classes for the residual variance was the most adequate and parsimonious model to describe the covariance structure of the data...

Objective: An experiment was conducted to determine the effect of superdosing phytase on productive performance and egg quality in laying hens. Methods: A total of 200 42-wk-old Hy-Line Brown laying hens were allotted into 1 of 5 dietary treatments with 5 replicates consisting of 8 hens per replicate. The positive control (PC) and negative control diets (NC) were prepared based on the recommended P levels in layer diets. Supplemental phytase was added to the negative control diet at 10,000 (SD10), 20,000 (SD20), or 30,000 (SD30) FTU/kg...

Objective: To examine the effects of Rhaodobacter sphaeroides supplementation as a direct-fed microbial (DFM) on rumen fermentation in dairy cows and on CoQ10 transition into milk, an in vitro rumen simulation batch culture and an in vivo dairy cow experiments were conducted. Methods: The characteristics of in vitro ruminal fermentation were investigated using rumen fluids from six cannulated Holstein dairy cows at 2 h post-afternoon feeding. A control treatment was included in the experiments based on a typified total mixed ration (TMR) for lactating dairy cows, which was identical to the one used in the in vivo study, plus R...

Objective: The aim of this study was to calculate selection signatures at possible loci leading to population differentiation, as well as pattern of selection of agouti gene within the local goat breeds and its correlation among other animal species to reveal molecular evolution. Methods: The high Fst outlier method corresponding to Fst distribution was used to identify the loci subject to positive selection. According to the empirical distribution of Fst estimates, we selected the SNPs having high Fst outlier corresponded to the upper 1% of the distribution as the loci under selection...

Equine Chorionic Gonadotropin (eCG) is a gonadotrophic hormone secreted by endometrial cups of pregnant mare, which is used to induce follicular development. In the present study, single nucleotide polymorphisms (SNPs) in 5'-untranslated regions (5'-UTR) of eCG genes were screened across 10 horse breeds, including 7 Chinese indigenous breeds and 3 imported breeds. Four SNPs were identified in the 5'-UTR of the eCGα gene, and one of them was unique in the indigenous breeds. There were 2 SNPs detected at the 5' end of the eCGβ subunit gene, and one of them was only found in the Chinese breeds...

The purpose of this research was to analyze behavioral characteristics of Hanwoo (Bos taurus coreanae) steers for each season and growth stage to enable measurement of animal welfare level for precision livestock farming. A hundred-eight beef steers were divided into three equal groups at a Hanwoo farm according to their growth stage: growing stage (GS), 8months; early-fattening stage (EFS), 19months; and late-fattening stage (LFS), 30months. Twelve behavioral categories were continuously recorded for 13day-time hours in each four seasons with three replications...

OBJECTIVE: This study examines the genetic factors influencing the phenotypes (four economic traits:oleic acid [C18:1], monounsaturated fatty acids, carcass weight, and marbling score) 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 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: The early growth response (Egr) family consists of four members (Egr1, Egr2, Egr3, and Egr4) that are zinc finger transcription factors. Among them, Egr3 is involved in transcriptional regulation of target genes during muscle spindle formation and neurite outgrowth. We previously showed that the immunoreactive Egr3 is localized on oocyte spindle and accumulate near the microtubule organizing center during meiosis I in mice. Egr3 was also shown to be localized on spermatocytes...
