Effects of lactation on fetal survival and development in rabbit does mated shortly after parturition.
Primiparous rabbit does were mated within 12 h after parturition (d 0). They were immediately weaned (Group W; n = 31) or allowed to suckle 10 young rabbits (Group L; n = 32). Blood samples were collected at d 0, 7, 17, and 28. Feed intake and live weight were measured weekly and pregnant does (Group W, n = 24; Group L = 25) were slaughtered at d 28. Feed intake was 78% higher in L than in W fe...
متن کاملHyperlipidaemia during normal pregnancy, parturition and lactation.
Excessive accumulation of one or more of the major lipids in plasma can produce a marked increase in the risk of coronary heart diseases and other vascular complications. During and after pregnancy, changes in the levels of total cholesterol, triglyceride, low density lipoprotein-cholesterol, and high density lipoprotein-cholesterol have been described, but the amount of change varies from stud...
متن کاملIron metabolism during lactation in the rabbit.
I . Iron metabolism was studied during lactation in the rabbit by the intravenous injection of 59Fe in order to measure plasma Fe turnover, Fe transfer to the milk and Fe absorption by the suckling young. 2. Although the plasma and red cell volumes were elevated in the lactating animal a significant increase of plasma Fe turnover was not demonstrated. 3 . Between 2.5 and 11.5 yo of the injected...
متن کاملReproduction – parturition, neonatal physiology, lactation
Parturition – control • Parturition requires myometrial contractions and cervical softening. • The myometrium is a functional syncytium (coupled by gap junctions) so contractions are coordinated. Contractions occur because action potentials cause Ca influx; oestrogen-primed myometrium shows pacemaker potentials, which initiate APs if they are large enough. Prostaglandins liberate Ca from intrac...
متن کاملBenefits of Prepartum Nest-building Behaviour on Parturition and Lactation in Sows — A Review
It is well known that prepartum sows have an innate motivation to build a nest before parturition. Under commercial conditions, however, the farrowing crate, which is widely used in modern pig husbandry, inhibits this innate behaviour through the lack of space, materials, or both. Thus, restriction of nest-building behaviour could generate increased stress, resulting in a decrease in maternal e...
