Management strategies to reduce piglet pre-weaning mortality
Introduction Nowadays, swine production in Thailand has become more industrialized and the number of total born piglets per litter increase rapidly during the past decade. One of the most important factors to achieve a successful swine farming industry is to optimize farrowing management. The key success for intensive farrowing management include, among other factors, a proper farrowing supervi...
متن کاملEffects of Varying Creep Feed Duration on Pre-weaning and Post-weaning Performance and Behavior of Piglet and Sow
32 sows (Landrace×Yorkshire) and their litters were used to evaluate the effects of varying creep feed duration on pre-weaning, post-weaning performance of piglets and sows. Sows were randomly assigned with 1, 2 or 3+ parities into 1 of 4 treatments. Creep feeding was initiated at day 5, 10 and 15 from birth for treatment 1 (TRT1), 2 (TRT2) and (TRT3), respectively, with a control group provide...
متن کاملEffect of oral polyamine supplementation pre-weaning on piglet growth and intestinal characteristics.
A high proportion of piglets fail to adapt to the changing composition of their diet at weaning, resulting in weight loss and increased susceptibility to pathogens. Polyamines are present in sow milk and promote neonatal maturation of the gut. We hypothesised that oral spermine and spermidine supplementation before weaning would increase piglet growth and promote gastrointestinal development at...
متن کاملInbreeding effects on lamb pre-weaning growth traits and survival in three Iranian sheep breeds
The present study was performed to study the effect of inbreeding on the pre-weaning growth traits including the birth weight (BW), weaning weight (WW), average daily gain (ADG), Kleiber ratio (KR) and lamb survival from birth to weaning (SUR) in Baluchi, Iran-Black and Zandi sheep. Significant positive inbreeding trends were found only for Baluchi and Iran-Black breeds as 0.038 and 0.278, resp...
متن کاملPre-Weaning Mortality in Pig-Causes and Management
Although the above data indicate that preweaning mortality is attributed to very discrete causes, in reality piglets typically die from an interaction of several possible causes of death. For instance, research has shown that small piglets are more susceptible to cold and therefore will lie more closely to their dam to obtain warmth. In this situation it is easy to see that a piglet such as thi...
