Effects of dietary polyunsaturated fatty acids on ovarian function and prostaglandin secretion in lactating dairy cows
As lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on PGFM secretion, ovarian function and blood metabolites is investigated. In this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous Holstein co...
متن کاملeffect of dietary omega-3 fatty acids on ovarian and insulin dynamic in holstein dairy cows
the purposes of this study were to evaluate of ovarian and insulin dynamics in dairy cows fed omega-3 fatty acid source. ten holstein multiparous cows were selected and after adaptation period given diets containing palm oil (control) and fish oil (treatment) from day -40 to 60 after calving. the study carried to show the effect of omega-3 fatty acids on insulin resistance. glucose tolerance te...
متن کاملA field study on glucose, non-esterified fatty acids, beta-hydroxybutyrate and thyroid hormones in dairy cows during the breeding period in Fars province, Iran
Background: It was hypothesized that under apparently good management practices in dairy farms, some cows may not be metabolically perfect during the breeding period and this may affect their performance. Aims: This study was conducted to assess probable metabolic drawbacks in mid-lactation dairy cows affecting their performance. Methods: Thirt...
متن کاملPlasma glucose, non-esterified fatty acids and amino acids in Huntington's chorea.
1. The metabolic responses to an oral glucose tolerance test (100 g) and an intravenous insulin provocation test (0-1 i.u./kg) were studied in nine control subjects and nine patients with Huntington's chorea. 2. Plasma glucose responses to these stimuli were identical in both groups. 3. High fasting concentrations of non-esterified fatty acid (NEFA) were recorded in the choreic patients when co...
متن کاملEffects of selenium-rich yeast supplementation on the plasma progesterone levels of postpartum dairy cows
OBJECTIVE The effects of the pre- and postpartum supplementation of cows with Se on their plasma P4 concentrations after calving were investigated. METHODS Thirty-four Holstein cows were used to investigate the effects of dietary selenium supplementation on the postpartum recovery of the luteal function in cows. Selenium-rich yeast (containing 300 ppm selenium) was mixed with total mixed rati...
