Nucleic acid ‐extracted torula yeast from the paper industry as a protein feed for ruminants: A comparison with soybean meal
AbstractWe compared nucleic acid-extracted torula yeast (NTY) with soybean meal (SBM) to evaluate NTY as a potential protein feed for ruminants in a metabolic trial using four castrated male goats. NTY was replaced isonitrogenously with SBM at a 25% crude protein (CP) level on a dry matter (DM) basis. NTY has 55% CP and 74% total digestive nutrients on DM. Absorbed N was lower on the NTY diet, but since the urinary N excretion was lower on the NTY diet, no significant between-diet difference in retained N was observed. The efficiency of N utilization (retained N/absorbed N) was significantly higher on the NTY diet. The Lys...

Vitrification of immature oocytes in pigs
AbstractCryopreservation of oocytes is an important technology for the in vitro gene banking of female germplasm. Although slow freezing is not feasible, porcine oocytes survive vitrification at high rates. Cryopreservation at the germinal vesicle stage appears to be more advantageous than that at the metaphase-II stage. Several factors are considered to affect the success of vitrification and subsequent utilization of immature porcine oocytes such as the device, the protocols for cryoprotectant application, warming, and the post-warming culture. Although live piglets could be obtained from vitrified immature oocytes, thei...

Intraday and interday variations of milk fatty acids in dairy cows in early and late lactation
This study aimed to determine an appropriate sampling method for milk FA in a practical farm condition based on intraday and interday variations in milk FA composition during early and late lactation stages. Milk samples were collected in the morning (07:00 –08:00 h) and afternoon (16:30–17:30 h) for five consecutive days during early and late lactation. Within the day, de novo FA as the total FA basis was higher in the morning than in the afternoon, whereas preformed FA as the total FA basis was lower in the morning than in the afternoon. The weighted averages of milk FA composition according to milk yield collect...

Feed characteristics of dried corn grain and corn grain silage produced in Japan compared with imported corn grain
AbstractWe compared the in situ dry matter degradability (ISDMD) and crude protein degradability (ISCPD) of high-moisture corn grain silage and dried corn grains produced in Japan (JHC and JDC, respectively) with corn grains imported from the United States (USC), Brazil (BRC), and South Africa (SAC). The ISDMD values of USC, BAC, and SAC were between those of JHC and JDC, but ISDMD did not differ significantly between USC and SAC. In contrast, ISDMD was lower for BAC than USC and SAC. Overall, our results indicate that ISDMD and ISCPD in the rumen differ between corn grains sources (domestic compared with imported and betw...

Low oxygen tension during in vitro embryo production improves the yield, quality, and cryotolerance of bovine blastocysts
In this study, the interaction of O2 tension and status (fresh or vitrified/warmed) affected the transcript abundance ofSOD2,AQP3, andBAX in blastocysts. These results highlight the role of low O2 tension during bovine maturation and fertilization and provide support to using 5% O2 throughout all stages of bovine in vitro embryo production.

Method for evaluating milk production in mouse mammary gland
AbstractLactation is a characteristic physiological function of mammals and is important for nourishing infants and the dairy industry; however, the molecular mechanisms underlying the function remain to be elucidated. A technique to directly evaluate the quantity and quality of milk in mice is necessary for the study of the lactation mechanism in vivo. By measuring the changes in milk amount after different durations of milk accumulation (0 –24 h) using a ductal cannulation technique and oxytocin supplementation, we estimated the milk production rate at a single mammary gland level. In addition, collected milk was ava...

Transportation ‐induced nausea‐like behavior in goats and the effects of anti‐motion sickness medication
This study investigated the nausea-like behavior induced by road transportation in goats, and the effects of an anti-motion sickness (MS) medication on this behavior. In the first experiment, 11 adult Shiba goats were road transported twice with either a saline (control) or a commercial anti-MS medication (Travelmin) injection at the first or second transportation. Almost all goats showed nausea-like behavior, which was defined as pointing their heads downward, closing their eyes, and staying relatively still. These goats did not respond when they were touched during blood collection. The anti-MS medication significantly r...

The role of endoplasmic reticulum stress in metabolic diseases and mammary epithelial cell homeostasis in dairy cows
AbstractHigh-yielding dairy cows undergo various physiological stresses during the transitional phase of the calving cycle. In this period, they experience negative energy balance, subjecting the liver to significant metabolic stress from an influx of nonesterified fatty acids. This metabolic stress not only impairs liver function but also diminishes milk production. Early lactation dairy cows may develop endoplasmic reticulum (ER) stress in the liver, potentially leading to liver-related diseases and contributing to ER stress in mammary epithelial cells, resulting in decreased milk production. Natural products that allevi...

Condensed tannin ‐induced variations in the rumen metabolome and the correlation with fermentation characteristics in goats
In this study, we characterized the effects of CT dietary inclusion at 2% (wt/wt) dry matter on the goat rumen metabolome and fermentation characteristics. Barley (BA) and corn (CN) were separately used as basal grain for the control rations, and rations supplemented with CT were BACT and CNCT, respectively. The rations were tested using eight Japanese Shiba × Saanen goats in a replicated 4 × 4 Latin square arrangement (28 days for each period). Ruminal fluid was obtained on day 25 of each period, and ultra-performance liquid chromatography–mass spectrometry (UPLC–MS) analysis was performed. Metabolites fr...

A method of calculating weighted values of objective traits for BLUP of breeding values to achieve relative desired changes
AbstractA method of calculating weighted values for objective traits from the phenotypic records of all animals in a population was devised as an alternative to the conventional method of calculating weighted values from a family selection index. The genetic improvement of this method was verified by Monte Carlo computer simulation. A base population consisting of 10 males and 50 females, and five separate generations, other than the base population that had been randomly selected, was bred for two traits with different heritabilities. The breeding values of animals in generation five were estimated using the bivariate BLU...
