Recent Advances In The Immunology And Uterine Microbiology Of Healthy Cows And Cows That Develop Uterine Disease, Klibs N. Galvao, Jose Eduardo P. Santos Jan 2014

Recent Advances In The Immunology And Uterine Microbiology Of Healthy Cows And Cows That Develop Uterine Disease, Klibs N. Galvao, Jose Eduardo P. Santos

Turkish Journal of Veterinary & Animal Sciences

Uterine diseases are highly prevalent in dairy cows. Causes of uterine diseases are multifactorial. There is good evidence for the susceptibility of the host and for the role of pathogenic bacteria, and less evidence for the effect of the environment. Uterine and leukocyte immune response is impaired early postpartum in cows that develop uterine disease. The decrease in immune function is associated with a decrease in calcium postpartum and an increase in NEFA and BHBA. Both endometrial cells and granulosal cells possess toll-like receptors (TLR) that can recognize and mount an inflammatory response to pathogen-associated molecular patterns (PAMPs) such as …

Turkish Journal of Veterinary & Animal Sciences

Dietary supplementation effects of 0%, 0.25%, 0.5%, and 1% glutamine were investigated on the performance and development of the gastrointestinal tract in broilers reared under hot conditions. No significant differences were observed between the treatments for feed intake and feed conversion ratio during the starter period, grower period, or entire experiment (P > 0.05). During the grower period, only 0.5% glutamine-fed birds had higher body weight gain than others (P < 0.05). For the entire period, body weight gain of 0.5% glutamine-fed birds was greater than that of 0.00% and 0.25% glutamine-fed ones (P < 0.05). Furthermore, 0.5% glutamine-fed birds showed longer villus height than other birds (P < 0.05). In the jejunum, both 0.5% and 1% glutamine consumption caused longer villus height as compared to 0.00% and 0.25% glutamine (P < 0.05). Villus height of 0.25% glutamine-fed birds was higher than that of 0.00% glutamine-fed ones (P < 0.05). None of the ileum morphological parameters were affected by glutamine supplementation (P > 0.05). In conclusion, supplementation of 0.5% glutamine improved the intestinal morphology and body weight gain of broilers under heat stress.

Turkish Journal of Veterinary & Animal Sciences

To study the effects of royal jelly (RJ) on performance and fatty acid profiles, 168 unsexed 8-day-old quails (Coturnix coturnix japonica) were assigned to 4 treatment groups. Groups were arranged as follows: control (LSD; 160 cm2/quail and no supplementation), high stocking density (HSD; 80 cm2/quail and no supplementation), HSD-RJ 250 [80 cm2/quail and 250 mg/kg body weight (BW) RJ given orally], and HSD-RJ 500 (80 cm2/quail and 500 mg/kg BW RJ given orally). Body weight gain decreased significantly in the HSD group at day 42 (P < 0.01). Feed intake (FI) and feed conversion rate (FCR) were also significantly affected in the HSD group (P < 0.01). FI and FCR were improved by both doses of RJ. Both RJ doses increased total polyunsaturated fatty acid ratios in the breast, kidney (P < 0.001), leg, and liver (P < 0.05). Total saturated fatty acid ratios in leg (P < 0.01) and kidney (P < 0.05) tissues increased in the HSD group but decreased in the livers of HSD-RJ 250 group (P < 0.05). In conclusion, RJ supplementation improved performance parameters and unsaturated fatty acid ratios in the examined quail tissues.

Estimation Of Genetic And Phenotypic Parameters For Daily Milk Yield Of Black Bengal Does, Md. Mohan Mia, Mobarak Akter Md. Yahia Khandoker, Syed Sakhawat Husain, Md. Omar Faruque, David Russell Notter

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the genetic and phenotypic parameters for daily milk yield (DMY) in Black Bengal does. Genetic parameters were estimated using a residual maximum likelihood procedure, fitting an animal model while ignoring maternal genetic or permanent environmental effects. The least squares mean for DMY was 354.76 g. DMY was significantly (P < 0.01) affected by parity, litter size, and season of kidding. The heritability of DMY was low (0.15) and the fact that the trait can only be measured in females suggests that progeny testing may be the best sire selection method for this trait.

Turkish Journal of Veterinary & Animal Sciences

In the present study, sensitive and mutant colonies of some ruminal bacterial species isolated from sheep, cattle, and buffalo were detected. We counted and considered \"mutant colonies\" the bacterial colonies grown in the clear inhibition zone in the Kirby-Bauer disk diffusion susceptibility test. Detected mutant colonies were higher in buffalo than in cattle and sheep. Duricef and metronidazole caused no mutations in any species. The others formed mutant colonies, where roxithromycin = polymyxin = chloramphenicol = gentamicin < erythromycin < vancomycin < piperacillin = cefotaxime < streptomycin < cefoperazone < ciprofloxacin < amikacin. Sheep had the highest number of sensitive isolates, and the number of sensitive isolates was dramatically lower in cattle and buffalo. There were no sensitive isolates with the antibiotic metronidazole, and there was a low number of sensitive isolates with duricef. The other antibiotics had more sensitive isolates (gentamicin = ciprofloxacin = amikacin > streptomycin = piperacillin > erythromycin > vancomycin = cefoperazone = cefotaxime > roxithromycin > polymyxin > chloramphenicol). The number of sensitive isolates of the different ruminant species for …

New Understanding Of An Old Phenomenon: Uncontrolled Factors And Misconceptions That Cast A Shadow Over Studies Of The ‘Male Effect’ On Reproduction In Small Ruminants, Trina Jorre De St Jorre, Penny Alison Rhian Hawken, Graeme Bruce Martin

Turkish Journal of Veterinary & Animal Sciences

In female sheep and goats, exposure to males can be used to induce ovulation and thus control and synchronise fertility. This 'male effect' offers simple, cost-effective, and hormone-free management of reproduction in flocks and herds but, despite decades of research, significant gaps in our knowledge impede commercial application. Many of these gaps can be traced back to misconceptions in the early documentation of the male effect, and others are the result of uncontrolled factors in experimental design. Consequently, it is often difficult to draw conclusions from past research, to further our understanding of the phenomenon, and to make recommendations for …

This research was conducted to study hormonal and metabolic statuses and to determine ultrasound criteria for early diagnosis of fetal growth retardation syndrome (FGRS) in dairy cows of Black-motley (n = 41) and Red-motley (n = 56) Holstein breeds. Concentrations of progesterone, testosterone, 17beta-estradiol, dehydroepiandrosterone sulfate, cortisol, and triiodothyronine in blood serum were assessed by immune-enzyme analysis. Concentrations of plasma L-ascorbic acid and nitrogen oxides, serum immune globulin, middle molecular peptides, and bactericidal and lysozyme activity were determined by spectrophotometry. On days 38-40 and 60-65 of gestation, FGRS in cows was associated with hypoprogesteronemia, decrease of adrenal and thyroid gland …

The aim of this study was to evaluate the effect of inbreeding on the yield and quality of bovine embryos. The data were obtained from 125 Holstein cows superovulated on 3 farms in the Czech Republic. In total, 125 flushings of embryos were analyzed, from which 761 embryos were obtained. Of all donors, 36 cows were inbred (199 embryos) and 89 cows were noninbred (562 embryos). The inbred cows were divided into 2 groups according to their inbreeding coefficient (FX) level. The low FX group (FX 1.26%-1.56%) had 23 cows and 147 embryos, and the high FX group (FX 3.1%-25%) …
