Welfare implications of artificial rearing and early weaning in sheep
Soon after parturition a lasting and mutual ewe–lamb bond is established. However, in an increasing number of intensive sheep farms, lambs are separated from the dam at an early age. When artificial rearing is applied lambs are often kept with mothers for 2 days to allow the ingestion of maternal colostrum and then abruptly removed from their dams. Thus, lambs experience a marked emotional stre...
متن کاملEffect of rearing system on pre-weaning growth, rumen development and its influence on post-weaning performance of lambs
Twenty-four 21-day-old Balouchi male lambs were equally divided into two groups. Twelve subjects were artificially reared (AR), twelve others were ewe reared (ER) and used as control. AR in comparison of ER lambs maintained higher concentrations of blood betaHydroxybutyric acid (BHBA); however glucose concentration was not affected by rearing system. Unlike the DNA content and cell size, the RN...
متن کاملNewborn traits associated with pre-weaning growth and survival in piglets
OBJECTIVE Piglet pre-weaning mortality is an important variable indicating the efficacy of farrowing management and animal well-being during lactation. The present study determined the association of newborn traits measured soon after birth with piglet pre-weaning mortality and growth. METHODS In total, 805 piglets born from 57 multiparous sows were investigated. Their blood oxygen saturation...
متن کاملSlow Growing Pre-Weaning Piglets Have Altered Adipokine Gene Expression
Growth rate affects adipose tissue development and variations in growth rate may potentially impact adipokine expression. Samples of subcutaneous (SQ) and perirenal (PR) adipose tissues and longissimus muscle were collected at day 21 of age from the fastest and slowest growing piglets within seven litters. Reverse transcription and real-time PCR were used to quantify adipokine mRNA abundance. L...
متن کاملObservations on the pre- and post-weaning behaviour of piglets reared in commercial indoor and outdoor environments
A number of behavioural problems are associated with weaning piglets including belly nosing, ear and tail biting, and low intake of solid food. These appear to be less pronounced in piglets reared on outdoor systems, which initially consume more solid food and show less belly nosing and aggression than comparable indoor-reared piglets. The objective of this study was to investigate how these di...
