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 ...
متن کاملSkin and leather characteristics of hair-type goats reared in a hot-humid region
Skin and leather characteristics of hair-type goats were studied in relation to their sex and age, using 100 randomly-selected skin from goats reared in east west Iran. Mean weights of skin and leather were 859.2±35.2 and 357.4±16.2 g, and the length and width of leather ranged from 60 to 121 and 41 to 87 cm, respectively. Age had a significant effect on the weight and area of skin and leather....
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 کاملEstimatation of Body Weight at Different Ages Using Linear and Some non Linear Regression Equations in a Duck Breed Reared in Hot and Humid Climate of Eastern India
The present study pertains to estimation of body weight of Vigova Super M, broiler ducks using linear and some non linear (log, inverse, quadratic, cubic, power, S, compound, logistic, growth and exponential) regression equations. Breast angle was considered as a predictor for estimation of the body weight. The results indicate that quadratic regression equation provided the most accurate estim...
