Lactation was induced in four non-pregnant, non-lactating buffaloes by subcutaneous injections of estradiol-17β and progesterone for 10 d @ 0.10 and 0.25 mg/kg b. w. /d respectively and Dexamethasone (@ 0.028 mg/kg b.w./d) treatment was given on 17 to 19 d. Milking was initiated on day 20. Biopsies of mammary glands were collected on 0, 7, 14, and 21 day from each animal. On 0 day of hormonal t...

BACKGROUND Shoulder ulcers can have a significant impact on the welfare of sows. In Denmark, rubber mats are used for treatment of shoulder ulcers. The objective of the study was to compare a treatment consisting of a combination of rubber mats and zinc ointment with the effect of local antibiotic spray (chlortetracycline) on shoulder ulcers. METHODS A total of 304 sows with shoulder ulcers w...

Administration of NK1 antagonists in adult animals attenuates the nociceptive response in the formalin test, indicating that the neurokinins and the NK1 receptor play a role in mediating this pain response. The number and distribution of NK1 receptors change dramatically during development, and the age at which they become involved in pain processing is not known. We examined the role of NK1 re...

BACKGROUND Nomegestrol acetate/17β-estradiol (NOMAC/E(2)) is a new monophasic oral contraceptive combining NOMAC (2.5 mg), a highly selective progesterone-derived progestogen, with E(2) (1.5 mg), which is structurally identical to endogenous estrogen. The objective of this study was to compare the effects on ovarian activity of two different NOMAC/E(2) regimens. METHODS This was a double-blind,...

The aim of the present study was to use blood flow evaluation of the CL at 14 days after embryo transfer to detect nonpregnant animals and optimize the management of bovine recipients. The estrous cycle was synchronized in 165 recipients, and the day of expected ovulation was considered to be Day 0. Embryo transfer was performed 7 days later, on Day 7. On Day 21, pregnancy was diagnosed on the ...

To investigate the hypothesis that acclimatization to altitude would result in a downregulation in muscle Na(+)-K(+)-ATPase pump concentration, tissue samples were obtained from the vastus lateralis muscle of six volunteers (5 males and 1 female), ranging in age from 24 to 35 yr, both before and within 3 days after a 21-day expedition to the summit of Mount Denali, Alaska (6,194 m). Na(+)-K(+)-...

Twenty-one days of restraint stress has been shown to affect hippocampal plasticity, neurogenesis, and spatial memory. Hippocampal glucocorticoid receptors (GR) and mineralocorticoid receptors (MR) are the main mediators of stress response and learning/memory processes. We studied the performance of male and female rats on a hippocampal-dependent spatial task after 21 days of restraint in relat...

The present study was conducted to study the effect of protected-glutamine (Gln) supplementation on dry matter intake (DMI), milk yield (MY) and composition, somatic cell counts (SCC) and blood parameters in fresh cows. Forty Holstein cows at zero day of parturition (calving day = day 0) were divided into four groups (n=10), and fed (ad libitum) with one of the diets including: basal d...

Transcriptome analyses were conducted on the ileal mucosa of 14- to 35-day-old piglets to investigate postnatal gut development during suckling and postweaning. The transcriptome profiles of 14-day-old suckling piglets showed a considerably higher number of differentially expressed genes than did those of 21-, 28-, and 35-day olds, indicating an intensive gut development during the first 14-21 ...

Materials and methods: Neonatal pigs (n = 96) from crossbred sows were assigned to three treatments, with four replicates per treatment. Treatments consisted of control (no iron), 200 mg injectable iron (iron dextran) at 2 days of age (Day 2), and 200 mg injectable iron (iron dextran) with 2000 IU oral vitamin A (vitamin A palmitate) on Day 2. The study was continued until Day 21. Blood samples...
