the aim of the present study was to determine the effect of dietary supplementation of pioglitazone (pgt) during transition period on the ovarian function and the incidence of several diseases after parturition. eighty holstein cows were randomly allocatted to four treatment groups (n=20) using a 2×2 factorial design. pioglitazone was fed for 14 day before the expected parturition time, or for...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
In order to investigate the relationship between insulin to glucagon ratio and metabolic factors in transitional period of dairy cows, 28 cows heifers with body condition score of 3.25- 3.75 were selected. Dairy cows received close up diet, from 21 days prepartum until parturition and lactation diet according to nutritional requirements after parturition. Blood was sampled at 10 days before and...
negative energy balance in pregnant ewes during last two month of gestation could result in fatal pregnancy toxemia and affects ewe and lamb health. the understanding of variations of energy related metabolites during this critical period may cast light upon to a better management of the situation. this study describes the variations of serum energy related biochemical metabolites at a period o...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Uterine function is often compromised in cattle by bacterial contamination of the uterine lumen after parturition, and pathogenic bacteria often persist, causing uterine disease, a key cause of infertility in cattle. However, the definition or characterization of uterine disease frequently lacks precision or varies among research groups. The aim of the present paper was to provide clear clinica...
the purpose of present study is testing influence of injection oxytocin immediately after parturition and injection prostaglandin f2α, 20 to 25 days after parturition in dairy cows upon process of uterus contraction distance between delivery till first estrus distance between parturition till first and second semenation, amount of pregnancy at first semenation and number of semenation for every...
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...
