Inbreeding and Its Effects on Body Weight,Kleiber Ratio, Body Measurements, Greasy Fleece Weight and Reproductive Traits of Makooei Sheep Breed
A pedigree file consisting of 5860 individuals, 167 sires and 1582 dams collected at Makooei sheep breeding station (MSBS) during a period of 24 years (1990 to 2013) was used to calculate the inbreeding coefficients to reveal any probable effects of inbreeding (F) on the studied traits. The studied traits were classified to the five main groups including body weight, Kleiber ratio, body measure...
متن کاملGenetic analysis of fleece and post-weaning body weight traits in Makuie sheep.
Estimation of genetic parameters is the most important component of an organized selection program. With respect to economic traits, such as wool and mutton traits, production costs can be reduced through a suitable selection program focused on genetic improvement. This study aimed to evaluate genetic parameters of fleece and post-weaning growth traits in sheep. Greasy fleece weight at 6, 16, 2...
متن کاملEstimating Genetic Parameters of Body Weight Traits in Kourdi Sheep
For estimating genetic parameters for body weight traits in Kourdi sheep data were collected from 1996 to 2013 in Kourdi Breeding Station in Northern Khorasan province of Iran. Studied traits were birth weight (BW), weaning weight (WW), six-month weight (6MW), nine-month weight (9MW) and yearling weight (YW). The fixed effects in the model were lambing year, sex, type of birth and age of dam. (...
متن کاملProduction performance, repeatability and heritability estimates for live weight, fleece weight and fiber characteristics of alpacas in New Zealand.
The production performance, repeatability and heritability estimates for live weight, fleece weight and fiber characteristics of alpacas farmed in the South Island of New Zealand are reported. Male alpacas produced heavier fleeces (p<0.001) than females, but with relatively similar fiber diameter. Mean (S.E.) shearing weight, greasy fleece weight (GFW), clean fleece weight (CFW), yield, staple ...
متن کاملThe Estimation of Body Weight from Body Measurements in Kilakarsal Sheep of Tamil Nadu, India
Data on body weight and body measurements (body length, height at withers, chest girth and paunch girth) of adult Kilakarsal sheep have been collected from 124 adult animals managed at the farmers filed in Tirunelveli districts of Tami Nadu, India to estimate the body weight from body measurements. The data were subjected to standard statistical analysis using SPSS software and linear regressio...
