Genetic relationship between superovulatory response traits and carcass traits in Japanese Black cattle
AbstractWe estimated the genetic correlations between superovulatory response traits and carcass traits in Japanese Black cattle. As regards the superovulatory response traits in cows, we analyzed the phenotypic records of the total number of embryos and oocytes (TNE) and the number of good embryos (NGE) collected from 1532 donors between 2008 and 2018. As regards the carcass traits in fattened animals, we analyzed the phenotypic records for cold carcass weight, rib eye area, rib thickness, subcutaneous fat thickness, estimated yield percent, and marbling score for 1448 progenies derived from 596 donors and slaughtered bet...

Predictability of carcass traits in live Tan sheep by real ‐time ultrasound technology with least‐squares support vector machines
This study aimed to investigate the performance of least-squares support vector machines to predict carcass characteristics in Tan sheep using noninvasive in vivo measurements. A total of 80 six-month-old Tan sheep (37 rams and 43 ewes) were examined. Back fat thickness and eye muscle area between the 12th and 13th ribs were measured using real-time ultrasound in live Tan sheep. All carcasses were dissected to hind leg, longissimus dorsi muscle, lean meat, fat, and bone to determine carcass composition. Multiple linear regression (MLR), partial least squares regression (PLSR), and least-squares support vector machines (LSS...

Effect of timing of paddock allocation in tropical grass on performance, nitrogen excretion, and enteric methane emissions from dairy cows
The objective of this study was to investigate the influence of timing of paddock allocation (AM or PM) in tropical grass on nutritive value of the herbage, dry matter intake (DMI), milk yield and composition, ruminal fermentation, nitrogen excretion, and enteric CH4 emissions of dairy cows. Twenty cows were grouped in pairs and randomly distributed within pair to one of two treatments. PM herbage had greater contents of dry matter (DM), soluble carbohydrates, starch, and nonfibrous carbohydrate to protein ratio and lower contents of neutral detergent fiber and acid detergent fiber. There was no treatment effect on DMI, N ...

Effect of high ‐concentrate diets on mRNA expression of genes related to muscle fiber type and metabolism of psoas major muscle in goats
In this study, two treatment groups were set up: high concentrate group (HC) and control group (C). The expression of genes related to muscle type and metabolism of the PM was examined by quantitative PCR. The results showed that high concentrate promoted the conversion of PM fibers from intermediate to slow type at the mRNA level, improved the absorption, transport, and oxidation of fat by PM, and upregulated the expression of calpain system. These changes may be regulated by the involvement of differential expression ofMSTN,Myf-5, andIGF-2. These results suggest that high concentrate may exert a positive effect on skelet...

Effects of the methionine hydroxyl analog chelated microminerals on growth performance, antioxidant status, and immune response of growing –finishing pigs
In conclusion, treatment with 1/5M HA-M and 2/5MHA-M could reduce the excretion of fecal microminerals and improve the immune function and antioxidant capacity compared with the ITM group. (Source: Animal Science Journal)

Quantitative analysis of the serum proteome during early pregnancy in mares
AbstractEquine pregnancy is currently diagnosed by rectal palpation, ultrasonographic examination, or by measuring changes in hormones in the blood. In the present study, we identified proteins that are differentially expressed in the sera of early pregnant and non-pregnant mares in order to develop a novel method for diagnosing equine pregnancy. Serum samples were obtained from 18 adult mares, pregnancy at day 32 after ovulation (n = 9) and in diestrus (n = 9). Proteomic analysis of the samples was conducted using liquid chromatography–electrospray ionization–tandem mass spectrometry. We identified 467 protein...

Effects of wood kraft pulp as a partial replacement for roughage on rumen fermentation and productivity in dairy cows
In this study, we evaluated the partial replacement of roughage with wood kraft pulp (KP) on rumen fermentation and productivity of dairy cows. Eighteen cows were divided into control and KP groups. The KP group started adaptation to KP 3 weeks before calving; after calving, they were fed a total mixed ration for 12 weeks, wherein 18% Timothy hay was replaced with KP. The dry matter intake, body weight, and milk yield and composition were similar in the control and KP groups. The average daily rumen pH was higher with KP feeding, and the average daily ruminal temperature remained lower at 16 days after calving (P &...

Relationship of parathyroid hormone ‐related protein and neonatal mineral metabolism in dairy cow placentas
This study clarified the relationship between PTHrP in the placenta of dairy cows and minerals in the fetal blood. Blood samples were obtained from 21 Holstein cows and 17 neonatal calves as well as 12 umbilical veins and arteries during cesarean section. After fetus removal, 13 caruncles and cotyledons were obtained. Concentrations of plasma PTHrP and serum minerals were measured. Real-time polymerase chain reaction (RT-qPCR) analyzed the gene expression of PTHrP and CaSR in the placenta. As a result, serum Ca and inorganic phosphorus concentrations in the neonate, umbilical vein, and artery were significantly higher than...
