Genetic Evaluation of Growth Rate and Efficiency Related Traits in Raeini Cashmere Goat
Growth efficiency-related traits are of economic importance for genetically improving of small ruminants especially in tropics with pastures of low quality and quantity. Data on body weights of Raeini Cashmere goat collected from 1979 to 2012 in Raeini breeding station, Kerman province, south-eastern part of Iran were used for estimating the genetic parameters of average daily gain from birth t...
متن کاملEstimation of Genetic Parameters for Lactation Curve Traits in Holstein Dairy Cows in Iran
The objectives were to estimate (co)variance components and genetic parameters for lactation curve traits in Holstein dairy cows in Iran. The used data were records on Holstein cows collected during January 2003 to December 2012 by the Animal Breeding Center of Iran (Karaj, Iran). In order to describe the lactation curve, an incomplete gamma function was fitted to 691200 test-day records on 962...
متن کاملEstimation of Gompertz growth curve parameters by a non- linear mixed effects model
Abstract Simulated growth data with parameters appropriate for pigs were generated through a 2 step process. First, a linear mixed model was used to produce Gompertz growth curve coefficients for each pig. Then, 30 weekly weights were produced using the coefficients. Simulated pedigree had 3 generations without selection: 10 unrelated grandsires and 200 sires, each with 24 tested offspring. A m...
متن کاملa genetic analysis of growth traits in raieni cashmere goat using multivariate animal model
genetic analysis of growth traits including body weight recorded at birth (bwt), 3 (3bwt), 6 (6bwt), 9 (9bwt) and 12 (12bwt) months of age was carried out using 4107 records on raieni cashmere goats born from 206 sires and 1402 dams, during years 1992 to 2006. the records were collected from a resource flock in baft research station, situated in kerman province, iran. the importance of addition...
متن کاملGenetic variability and population structure of Raeini Cashmere goat breed assessed from pedigree analysis
Pedigree information which collected from 1979 to 2012 were used to study the genetic variability and population structure of Raeini Cashmere goat, taking kids born from 2009 to 2012 into account as reference population. Averages of inbreeding coefficients in whole and inbred populations were computed to be 0.04% and 4.41%, respectively. Considering the reference population, average inbreeding ...
