Polyvinyl alcohol, but not bovine serum albumin, promotes the induction of full ‐type hyperactivation in boar cyclic AMP analog‐treated spermatozoa
This study aimed to verify the effects of polyvinyl alcohol (PVA) and bovine serum albumin (BSA) on the induction of full-type hyperactivation in boar spermatozoa treated with a cyclic AMP analog (cBiMPS). Washed spermatozoa were treated with cBiMPS (100 μM) for 180 min. As shown in the assessment of sperm motility, PVA (0.05%–0.4%) significantly promoted the induction of full-type hyperactivation, whereas BSA (0.025%–0.4%) did not affect the induction. In comparative experiments, BSA (0.4%) effectively promoted the induction of full-type hyperactivation in bovine spermatozoa treated with cBiMPS, calyculin A (a p...

Effects of feeding wood kraft pulp silage containing sweet ‐potato shochu distillery by‐product on feed intake, feed digestibility, rumen fermentation, blood components, and growth performance in Japanese Black fattening steers during early period
AbstractThe effects of long-term feeding of wood kraft pulp (KP) silage containing sweet-potato shochu distillery by-product (SDP) on feed intake, feed digestibility, rumen fermentation, and growth performance of Japanese Black steers were investigated during the early fattening period. Ten Japanese Black steers (9.8 ± 0.6 months of age) were used in this study. Five steers (KP group) were fed KP silage as a replacement for 10% timothy hay (dry matter bases), in contrast to the other five (control group). KP silage consisted of 92.9% KP and 7.1% SDP (dry matter bases). The experiment was conducted for 18 weeks. N...

Effect of immersion in low ‐pH solution on physicochemical properties of high‐pH venison
AbstractThe color of venison observed at a high-pH is not preferred by consumers. However, the physicochemical properties of venison soaked in a low-pH solution to lower its high-pH are unknown. We investigated the effect of immersion in a low-pH solution on the physicochemical properties of a high-pH venison. The pH ofM. longissimus thoracis from seven female wild deer (Cervus nippon) was measured and divided into normal-pH venison and high-pH venison groups. The a* and b* values for high-pH venison were lower than those for normal-pH venison before storage. There was no significant difference in the pH between high-pH ve...

Effect of mastitis incidence on litter size, litter weight, and milk composition of rabbit does
This study aimed to examine the effect of mastitis incidence on the litter size, litter birth weight, and milk composition of Hycole does on a commercial rabbit farm during their third and fourth parity. At third parity does were assigned to the “No mastitis” (n = 30) and “Mastitis” (n = 28) groups on the basis of visible abscesses in the mammary gland area. The microbiological analysis revealed the presence of different pathogenic bacteria. At third parity, “Mastitis” females had fewer kits than the “No mastitis” group, and the average birth weight was lower. On day 2 of the third lactation, “Mas...

Effects of dietary bamboo (Phyllostachys pubescens Mazel) culm powder on blood properties and intestinal environment of rabbits
This study investigated the effects of bamboo powder as an alternative feed for rabbits. The normal hay diet of rabbits was replaced with bamboo culm powder (10% and 20%) and fed to the rabbits until they were 90 days old. The blood samples were collected when the rabbits were 46, 66, and 90 days old to assess the effects of bamboo powder on blood parameters. The organs and intestinal contents were harvested at the age of 90 days, and the functions and morphologies of different organs were evaluated. The concentration of short-chain fatty acids (SCFAs) and the composition of microbiota in the cecum were measured. Su...

Effect of 6 ‐n‐propyl‐2‐thiouracil or dexamethasone administration on the responses of antimicrobial components in goat milk to intramammary lipopolysaccharide infusion
This study aimed to elucidate the effect of hypothyroidism and hypercortisolism on the response of mammary innate immune function to inflammation caused byEscherichia coli in dairy goats. To induce hypothyroidism and hypercortisolism, we administered 6-n-propyl-2-thiouracil (PTU; for 21 days) and dexamethasone (DEX; for 5 days), respectively, to six goats each; six goats without treatment were used as the control group. After treatment, lipopolysaccharide (LPS) fromE. coli O111 was infused into the mammary gland. Somatic cell counts (SCC) and levels of lactoferrin (LF), S100A7, immunoglobulin A (IgA), and interleuki...

Optimal value for the exponential term of Wilmink's function according to current Holstein lactation curves in Japan
AbstractWe compared values of Wilmink's exponential term to describe the lactation curves of Holstein cows in Japan. Data were a total of 100,971,798 test-day records from the first through fifth parities during 1991 through 2018. The lactation curve model used fourth-order Legendre polynomials and Wilmink's exponential term. In total, 810 analyses were executed to compare six values ( −0.02, −0.03, …, −0.07) for the exponential term to select the one that yielded the smallest root mean square error. For all parities, daily milk yield and lactation persistency increased consistently and peak lactation days occurred...

Comprehensive assessment of genetic diversity, structure, and relationship in four Japanese cattle breeds by Illumina 50 K SNP array analysis
The objective of this study was to comprehensively assess the genetic diversity, structure, relationship, and the degree of influence from foreign breeds (Angus, Simmental, Hanwoo, Shorthorn, Ayrshire, Brown Swiss, and Devon) in the Japanese cattle breeds using Illumina 50 K SNP array. In principal component analysis, each Japanese breed was separately clustered except for Japanese Shorthorn and Shorthorn. Japanese cattle breeds also showed different genetic components from each other at K ≥ 5 in population structure analysis. Japanese Shorthorn, on the other hand, had a very similar structure to Shorthorn at K ...
