objective: estimation of genetic parameters for kleiber ratio (kr) and genetic trends for pre-weaning weights of arabi sheep has not been previously conducted.methods: data and pedigree information were collected at the khuzestan ramin agricultural and natural resources university, animal science research station, located in southwest iran, from 2001 to 2008. (co)variance components and corresp...

the objective of the present study was to evaluate the effects of inbreeding on average daily gains and kleiber ratios in moghani sheep. traits included average daily gain from birth to 3 months (adg1), average daily gain from birth to 6 months (adg2), average daily gain from 3 months to 6 months (adg3), average daily gain from 3 months to 9 months (adg4), average daily gain from 3 months to ye...

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...

The objective of this study was to evaluate the growth and efficiency-related traits Boer x Central Highland goats. Besides, genetic non-genetic factors affecting (Kleiber ratios) were identified. Data collected for nine years a general linear model procedure SAS employed detect significance fixed effects. overall least-squares mean live weight at birth, 3-, 6-, 9- 12 months age 2.52±0.01, 9.81...

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...
