Article
We investigated whether prepartum levels of serum bone biomarkers are related to the degree of parturient hypocalcaemia and risk of milk fever (MF) in dairy cows with advancing parity. A total of 58 late-pregnant cattle were assigned to four groups: nulliparous, primiparous, multiparous in the 2nd lactation and multiparous in the 3rd–5th lactation....
Article
This study aimed to evaluate the effects of rumen‐protected lysine (RPL) supplementation during the close‐up period on blood metabolites and calf growth. Forty multiparous Holstein dams were selected based on parity, body condition score, and expected calving date, and randomly assigned to a group: with RPL (n = 22) or without (control [CON], n = 1...
Article
This study examined the effects of the glycerol pellet supply during the close-up dry period in dairy cows. The peripartum metabolic status, postpartum disease, milk yield, and recovery of reproductive function were examined in 41 dry Holstein cows. Daily doses of 200 g of glycerol pellets containing 40 % glycerol (Gly group, n=20) or 200 g of plac...
Article
Dairy cattle management lacks consideration of fetal breed, the effect of which on fetal growth and nutrition are unclear. We investigated blood parameters in 12 late‐pregnant Holstein heifers with similar (Holstein, n = 5) or different (Japanese Black [n = 4] or F1 cross [n = 3]; Holstein × Japanese Black) fetus breeds and in their umbilical cords...

Castration is one of the most frequently performed surgical procedures. It is performed to improve productivity in the beef cattle industry, and particularly, open orchiectomy is widely carried out in Japan. In the present report, we describe three Japanese Black steers with scrotal abscess due to surgical site infection(SSI)after castration. The s...

A 1-day-old male calf presented with clinical signs of severe progressive abdominal distension. Abdominal radiographic and ultrasonic images revealed several loop-like structures in the small intestine, which were indicative of gas retention. Experimental laparotomy was performed. However, the calf died during surgery. At necropsy, a round, well-ci...

Dairy cows experience hypocalcemia at the onset of lactation; however, the contribution of bone metabolism to circulating Ca concentrations during the periparturient period is not well understood. Osteoprotegerin (OPG) protects against loss of skeletal mass by regulating osteoclastogenesis. We previously reported that the bone resorption increased...

Interferon tau plays an important role in establishing bovine pregnancy. Interferon-stimulated genes (ISGs) have been examined to identify a suitable indicator for the diagnosis of early gestation in cows. Although ISGs can be specifically detected in peripheral white blood cells during early gestation, its reliability remains to be validated. In t...
