Biology of somatotropin in growth and lactation of domestic animals.
Impressive progress has been made during the past 15 years in our understanding of the biology of somatotropin (ST) in domestic animals. In part, this progress was sparked by advances in biotechnology that made feasible the production of large quantities of recombinant bovine ST (bST) and porcine ST (pST). The availability of recombinant bST and pST resulted in an exponential increase in invest...
متن کاملPig weaning weight and changes in hematology and blood chemistry of sows injected with recombinant porcine somatotropin during lactation.
Weaning weight of pigs on d 18 to 21 of age was used to determine the effects of recombinant porcine somatotropin (rpST) on lactational performance of their dams. Crossbred Landrace x Yorkshire sows (n = 180, 202 to 270 kg BW) were assigned to receive daily i.m. injections of either 0, 8, or 16 mg of rpST on lactation d 7 to 20. Initially, injections of 16 mg of rpST/d caused 100% mortality (fo...
متن کاملAlcohol and Lactation
Background: Breastfeeding is the safest and best method for nurturing infant growth and health. While the harmful effects of alcohol during pregnancy are well-established, the consequences of alcohol intake during lactation have been far less examined. The effects of alcohol intake with large amounts noted on the infant include drowsiness, diaphoresis, deep sleep, weakness, decrease in linear g...
متن کاملA Successful Induction of Lactation in Surrogate Pregnancy with Metoclopramide and Review of Lactation Induction
In surrogate pregnancies genetic parents have little opportunity for early bonding with their infants either prenatally (in utero) or during the immediate postnatal period. Procedures commonly used to induce lactation include both pharmacologic and nonpharmacologic methods often in combination. Studies reporting induced lactation are sparse due to the rarity of augmented lactation. Here we repo...
متن کاملPulsatile release of somatotropin related to meal feeding and somatotropin response to secretagogues in horses.
Our goal was to establish a time of day and(or) interval from feeding that would avoid the refractory period after a somatotropin (ST) surge and optimize the responsiveness of horses to ST secretagogues. Two experiments were conducted with eight geldings conditioned to consume grain at 0800 and 1600 daily. In Exp. 1, during a 24-h period, these geldings averaged 3.2 +/- .3 pulses of ST with pea...
