Quantitative relationship between the number of cross ‐fostering piglets and subsequent productivity of sows on commercial swine farms
AbstractThe present study aimed to investigate the quantitative relationship between the number of cross-fostering (CF) piglets and subsequent productivity of sows. Data were obtained from seven commercial farms including 41,086 farrowing records. Sows were divided into those that fostered out three or more piglets (CF ≥ 3–), fostered out one or two piglets (CF1–2–), did not do CF (NCF), fostered in one or two piglets (CF1–2+), and fostered in three or more piglets (CF ≥ 3+). CF ≥ 3– sows had the lowest number of piglets weaned and the highest preweaning mortality rate, whereas CF ≥ 3+ s...

Estimates of genetic parameters for adenosine triphosphate ‐related compounds at different aging periods and NT5E genotypes in Japanese Black beef
AbstractPrevious studies on Japanese Black beef showed that single nucleotide polymorphisms in theecto-5 ′-nucleotidase (NT5E) gene affected the degradation rate of inosine 5 ′-monophosphate (IMP), which has contributed to theumami taste, especially between Postmortem Days 4 and 7. Therefore, this study estimated the genetic parameters of IMP and its degradation products on Postmortem Days 4 and 7 using the model with or without theNT5E genotype. The heritability estimates of IMP on Postmortem Days 4 and 7 were moderate by the model without theNT5E genotype (0.44 and 0.32, respectively). When theNT5E genotype was inclu...

Curcumin reduces oxidative stress and fat deposition in longissimus dorsi muscle of intrauterine growth ‐retarded finishing pigs
AbstractDietary curcumin possessing multiple biological activities may be an effective way to alleviate oxidative damage and fat deposition in intrauterine growth retardation (IUGR) finishing pigs. Therefore, this study was conducted to evaluate effects of dietary curcumin on meat quality, antioxidant capacity, and fat deposition oflongissimus dorsi muscle in IUGR finishing pigs. Twelve normal birth weight (NBW) and 24 IUGR female piglets at 26 days of age were divided into 3 dietary groups: NBW (basal diet), IUGR (basal diet), and IUGR + Cur (basal diet supplemented with 200 mg/kg curcumin). The trial lasted for ...

The influence of breath concentration in the gas sample on the accuracy of methane to carbon dioxide ratio using the sniffer method in dairy cows
This study also assessed the effect of selective elimination by applying the threshold of CO2 concentration to the CH4/CO2 ratio. The gas measurement in the automatic milking system was conducted with 26 multiparous Holstein cows using an electric fan to manipulate the CO2 concentration in the sampled gas. Four different thresholds of the background-corrected CO2 concentrations (0, 0.025, 0.05, and 0.1%) were applied to every 1-s value of the individual gas measurement. Subsequently, three different upper limits of the proportion of eliminated values (none, 0.5, and 0.33) were applied to the individual records per milking....

Apple polyphenols improve intestinal barrier function by enhancing antioxidant capacity and suppressing inflammation in weaning piglets
This study aimed to examine the effects of apple polyphenols (APPs) on antioxidant capacity, immune and inflammatory response, and barrier function in weaning piglets. Results showed that APPs improved jejunal barrier function by increasing the villus height, villus height/crypt depth, the mRNA levels ofoccludin,mucin-1, andmucin-4 and up-regulating the protein expression of occluding (P < 0.05). As for antioxidant capacity, APPs increased the activities of total superoxide dismutase and glutathione peroxidase and total antioxidant capacity level in jejunum (P < 0.05). Besides, APPs up-regulated the protein...

Effect of different cow floor mat on the pressure in anterior knees of Holstein dry cows determined using pressure measurement sheet
AbstractTo analyze limb pain in tethered dairy cows, we compared three cow floor mat materials (pasture mat ® [PM], KKM rubber mat® [RM], and woodchip [WC]) with soil ground considering the pressure applied to the anterior knee of Holstein cows. Three Holstein dry cows (791.3 ± 44.6 kg, 3.8 ± 1.1 years old) moored at the Education and Research Center of Alpine Field Science of the Faculty of Agriculture, Shinshu University, were tested. Pressure applied to the anterior knee of the cow by four different floor mat materials was compared using a commercially available pressure measurement sheet. The sustained pr...

Longitudinal genetic analysis of semen production traits in Holstein bulls according to a random regression animal models on age
We examined two RRAMs with homogeneous and heterogeneous residual variances (RRAM1 and RRAM2, respectively). By using RRAM1, heritability for VOL and CON increased from 0.08 to 0.61 and 0.18 to 0.57, respectively, between 10 and 126 months of age. By using RRAM2, heritability for VOL increased from 0.11 to 0.28 between 10 and 24 months of age for young bulls and increased from 0.08 to 0.48 between 25 and 126 months of age for mature bulls; heritability for CON ranged from 0.18 to 0.19 for young bulls and increased from 0 .10 to 0.48 for mature bulls. Posterior genetic correlations between young ages and older ages w...
