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 کاملEffect of Including Inbreeding, Heterosis and Recombination Loss in Prediction of Breeding Values for Fertility Traits
Inbreeding results from the mating of related individuals and is becoming increasingly important in domestic livestock populations. Inbreeding depression is the reduction of the mean phenotypic value, particularly for traits connected with reproduction or fitness (Miglior et al., 1992). Inbreeding depression has been shown to decrease milk production by approximately 9-26 kg of milk per lactati...

15 صفحه اولPedigree analysis and inbreeding depression on growth traits in Brazilian Marchigiana and Bonsmara breeds.
The study of population structure by pedigree analysis is useful to identify important circumstances that affect the genetic history of populations. The intensive use of a small number of superior individuals may reduce the genetic diversity of populations. This situation is very common for the beef cattle breeds. Therefore, the objectives of the present study were to analyze the pedigree and p...
متن کاملInbreeding Effect on Genetic Parameters of Economic Traits in Moghani Sheep Breed
The aim of this study was to investigate the effect of inbreeding on the estimation of genetic parameters of weight traits at different ages in Moghani sheep. In the present study, the information of 11721 Moghani sheep in Jafarabad Moghan breeding station from 1987 to 2011 was used. Genetic parameters were estimated using single trait model with covariate and classification and without inbree...
