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 investigated the effects of Bacillus subtilis CSL2 administration before Salmonella challenge on the fecal microbiota and microbial functionality of Hy-line Brown (HLB) laying hens. Methods: Fecal samples were collected from control (CON), Salmonella-infected (SAL) and Salmonella-infected, probiotic-treated (PRO) groups before and after Salmonella challenge for microbiome analysis using 16S rRNA gene pyrosequencing. Results: Infection with Salmonella led to decreased microbial diversity in hen feces; diversity was recovered with Bacillus administration...

Objective: Calving ease (CE) is a complex reproductive trait of economic importance in dairy cattle. This study was aimed to investigate the genetic merits of CE for Holsteins in Korea. Methods: A total of 297,614 field records of CE, from 2000 to 2015, from first parity Holstein heifers were recorded initially. After necessary data pruning such as age at first calving (18-42 mo), gestation length, and presence of sire information, final datasets for CE consisted of 147,526 and 132,080 records for service sire calving ease (SCE) and daughter calving ease (DCE) evaluations, respectively...

Objective: Using medicinal plant by-products (MPBP) as feed additives may be an eco-friendly option as substitutes for feedstuffs and may assist in reducing the improper disposal of MPBP. Therefore, this study was conducted to evaluate the influences of medicinal plant by-products on the meat quality of Hanwoo steers fed a total mixed ration (TMR). Methods: Twenty seven steers (BW = 573 ± 57 kg) were randomly divided into three treatments with a control group and two tested groups as follows: control, 1000 g/kg TMR; treatment 1 (MPBP30), 970 g/kg TMR and 30 g/kg MPBP; treatment 2 (MPBP50), 950 g/kg TMR and 50 g/kg MPBP...

Objective: High NH3 emissions from poultry houses are reported to have negative impacts on health, welfare and safety of birds and human, and on the environment. Objective of the present study was to determine the effects of two litter amendments on the NH3 levels in broiler closed houses under hot-humid conditions. Methods: Giving a completely randomize design, nine closed houses, each housed 32500 birds on paddy husk litter, were randomly allocated into two treatment (Mizuho; a bacterial culture mix and Rydall OE; an enzymatic biocatalyst) and control groups...

Objective: Adipose tissue is no longer considered as an inert storage organ for lipid, but instead is thought to play an active role in regulating insulin effects via secretion adipokines. However, conflicting reports have emerged regarding the effects of adipokines. In this study, we investigated the role of adipokines in glucose metabolism and insulin sensitivity in obese Bama mini-pigs. Methods: An obesity model was established in Bama mini-pigs, by feeding with high-fat and high-sucrose diet for 30 weeks...

Objective: This study investigated the effect of fermented biogas residue (FBR) of wheat on the performance, serum biochemical parameters, and meat quality in pigs. Methods: We selected 128 pigs (the mean initial body weight is 40.24±3.08 kg) and randomly allocated them to 4 groups (1 control group and 3 treatment groups) with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received soybean meal, the treatment group fed diets containing 5%, 10%, and 15% fermented biomass residue (FBR), respectively (abbreviated as FBR5, FBR10 and FBR15, respectively)...

Lao PDR's recent accession to the World Trade Organization necessitates a greater understanding of the patterns and risk of livestock production in order to better align national policy with the Agreement on the Application of Sanitary and Phytosanitary Measures. This eco-health study describes the integration of market chain and zoonoses risk analyses at two strategic cross border points between Lao PDR, Thailand and Viet Nam. Information gained from smallholder farmer/trader interviews was integrated with serological surveys for pig-associated zoonoses - including hepatitis E virus, Taenia solium and Trichinella - to identify potential linkages between disease risk and pig production and slaughter in low input systems common across the country...
