Inbreeding 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...
متن کاملEffect of Inbreeding on Pre-weaning Growth Traits in Thalli Sheep
Pedigree records of 17250 Thalli sheep with 17030 lambings maintained at the Livestock Experiment Station, Rakh Ghulaman, Distt. Bhakkar, Pakistan during the period from 1975 to 2004 were utilized in the present study. Average values for birth weight, weights at 60 and 90 days of age, weaning weight and preweaning average daily gain were 4.11 ± 0.82, 11.58 ± 3.57, 14.92 ± 4.56, 18.95 ± 4.56 and...
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 کاملGenetic parameters for pre-weaning traits in Braunvieh cattle.
The objective of this study was to estimate genetic parameters for pre-weaning traits of Braunvieh cattle raised under tropical conditions in Brazil. The weight and weight gain parameters were birth weight (BW, N = 9955), weight at 120 days of age (W120, N = 5901), weaning weight at 205 days (WW, N = 6970), weight gain from birth to 205 days (GAIN205, N = 6013), weight gain from birth to 120 da...
