Comparison of Ordinary and Restricted Selection Indices on Genetic Gain of Body Weight in Iranian Moghani Sheep

The effect of ordinary and restricted selection indices on body weight at different ages changes in birth weight of Iranian Moghani sheep was studied. Traits in the aggregate genotype were birth weight (BW), body weights at 3 (BW3) and 12 months of age (BW12). Two ordinary selection indices (I1 and I2) and two restricted selection indices (R1 and R2) were constructed. BW and BW3 were included i...

Estimating 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. (...

Prepregnancy Body Mass Index and Pregnancy Weight Gain in Rural Regions of Guilan Province, Iran

Maternal nutritional status and weight gain throughout pregnancy affect the outcome of pregnancy. The objective of this study was to determine prepregnancy body mass index and total weight gain during pregnancy in women from rural areas of Guilan province, Iran. Prenatal and obstetrical records of 480 pregnant women who attended rural health centers between 2002 and 2003 including prepregnancy ...

Effects of Genetic and Non-genetic Factors on Body Weight and Carcass Related Traits in Two Strains of Japanese Quails

The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...
