Plasma prolactin, blood metabolites and milk production in bromocryptine-treated crossbred goats
To determine the effect of bromocryptine on plasma prolactin, metabolites and milk production, six healthy crossbred goats in their second or third lactation were selected from the institute's goat herd. The goats were injected with bromocryptine @ 5 mg per day intramuscularly for a period of 5 days during 55±60 days of lactation (period I) and treatment was repeated after 14 days for an additi...
متن کاملEffect of Bromocryptine on hormones and milk secretion in Murrah buffaloes ( Bubalus bubalis).
An experiment was carried out on 10 advance pregnant Murrah buffaloes to determine the role of hormones in milk secretion around parturition. Experimental animals were administered with a single injection of bromocryptine, @ 100 μg/kg BW, for 5 days before expected calving, whereas control group buffaloes were injected with placebo injections. Blood samples collected before parturition (-5,-4,-...
متن کاملRumen-protected conjugated linoleic acid supplementation to dairy cows in late pregnancy and early lactation: effects on milk composition, milk yield, blood metabolites and gene expression in liver
BACKGROUND Conjugated linoleic acid (CLA) is a collective term for isomers of octadecadienoic acid with conjugated double-bond system. Thus, it was the objective to investigate whether milk composition and metabolic key parameters are affected by adding CLA to the diet of dairy cows in the first four weeks of lactation. METHODS A study was carried out with five primiparous cows fed a CLA supp...
متن کاملThe effect of a low-protein ration on milk yield and plasma metabolites in Friesian heifers during early lactation.
1. Sixteen first-calf Friesian heifers were used in a continous treatment design experiment. For 2 weeks after calving they were given a 750 g concentrate, 250 g hay/kg ration with 169 g crude protein (nitrogen X 6.25; CP)/kg dry matter (DM). They were then divided into two groups of eight and given a high-protein (223 g CP/kg DM) or low-protein (107 g CP/kg DM) ration at the rate of 10.8 kg co...
متن کاملShort Term Changes in Plasma Hormones, Metabolites, Milk Yield and Physiological Responses in Epinephrine Administrated Cows
This investigation summarizes the effect of epinephrine administration on milk production and plasma hormones. The epinephrine and nor-epinephrine hormone are released during stress and may have adverse effect on milk yield of lactating animals. Lactating cows were administered epinephrine intravenously (@0.5 ug/kg body wt./ day) for a period of five days. Blood samples were collected before an...
