Although it is stated that there an increase in calf loss rates at the global level and especially modern dairy farms, this issue, which international animal welfare has not been adequately defined national, large farm, or small farm most developing Countries. The rate of deaths before, during, after birth between 2–20% heifers cows. Previous studies showed 75% occur during within first hour bi...

The study evaluated the effect of supplementation rumen protected choline (RPC) and fat (RPF) alone in combination, injection Vit-E + selenium on feed intake, blood metabolic profile postpartum fertility transition Gir cows. Forty advanced (8 months) pregnant cows were divided into five equal groups (T1 to T5, n=8) managed individually from 30 days prepartum till 60 postpartum. Cows T1 group fe...

Hepatic metabolic gene networks were studied in dairy cattle fed control (CON, 1.34 Mcal/kg) or higher energy (overfed (OVE), 1.62 Mcal/kg) diets during the last 45 days of pregnancy. A total of 57 target genes encompassing PPARα-targets/co-regulators, hepatokines, growth hormone (GH)/insulin-like growth factor 1 (IGF-1) axis, lipogenesis, and lipoprotein metabolism were evaluated on -14, 7, 14...

This study was aimed at demonstrating associations between peripheral biochemical parameters, endometrial leukocyte esterase (LE) and myeloperoxidase (MPO), and bacterial detection with the degree of endometrial inflammation, and determining the best time postpartum for diagnosing endometritis to predict subsequent fertility in dairy cows. Plasma albumin, blood urea nitrogen (BUN), total choles...

Forty-three Jersey calves were assigned randomly at birth to treatments that evaluated the method of weaning on growth, intake, and concentrations of blood metabolites that were indicative of ruminal development. The three experimental treatments were 1) milk replacer fed at 10% of BW until abrupt weaning at 35 d of age, 2) milk replacer fed at 10% of BW until 28 d and then at 5% of BW until we...

Twenty-four 21-day-old Balouchi male lambs were equally divided into two groups. Twelve subjects were artificially reared (AR), twelve others were ewe reared (ER) and used as control. AR in comparison of ER lambs maintained higher concentrations of blood betaHydroxybutyric acid (BHBA); however glucose concentration was not affected by rearing system. Unlike the DNA content and cell size, the RN...

The objectives of this study were to investigate the associations between peripheral blood neutrophil (PMN) function, energy status, and uterine health in periparturient dairy cows. Data were collected from 83 multiparous Holstein cows. Blood samples for PMN function determination were collected weekly from 1 week prior to calving (week -1) through 4 weeks after calving and again at 8 weeks aft...

This experiment was conducted to evaluate the effects of increasing concentrations of crude glycerin (CGLY) in diets on nutrient utilization, ruminal fermentation characteristics, and nitrogen utilization of goats. Four male crossbred (Thai Native×Anglo Nubian) goats, with an average initial weight of 26±3.0 kg, were randomly assigned according to a 4×4 Latin square design with four 21 days con...

Thirty-two cows, averaging 112 DIM, were assigned to four dietary treatments: 1) control, 2) Ca salts of fatty acids, 3) nicotinamide, and 4) Ca salts of fatty acids blended with nicotinamide during manufacture. Preliminary studies showed that nicotinamide survives blending with Ca salts of fatty acids during manufacture and that a blended mixture of nicotinamide and Ca salts of fatty acids gav...

* E-mail: [email protected] ABSTRACT This study was carried out on 68 naturally infected buffaloes with Theileria annulata, in addition to 25 parasite-free buffaloes, distributed in small herds at Dakahlia and Gharbya governorates, Egypt, to demonstrate the clinical picture associated with theileriosis, with particular emphasis on the oxidative stress and ketosis relationship. The clinical...
