Estimates of Genetic and Phenotypic Parameters for Milk Production in Moroccan Holstein-Friesian Cows
To satisfy the growing demand of the human population for milk, the Moroccan government set up a plan in 1975 to increase milk production. The most important genetic strategies were the introduction of improved dairy cattle, the institution of milk recording, and the extension of artificial insemination (AI). Thus, more than 10,000 Holstein and Friesian heifers were purchased annually from Euro...
متن کاملGenetic and Phenotypic Parameters for Milk Production Traits in the First and Second Lactation in Romanian Simmental Dairy Cows
The aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of Romanian Simmental dairy cattle. For the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
متن کاملEstimation of Phenotypic and Genetic Parameters of Egg Quality Traits of Azerbaijan Native Hens
The egg quality is one of the most important economic factors for layers that are crucial for hatchability and marketing. Given the low number of egg quality traits records, one of the approaches in estimating phenotypic and genetic parameters is multi trait analysis. The aim of this study was to estimate the phenotypic and genetic parameters of west Azerbaijan native hens egg quality traits by...
متن کاملEstimation of Genetic and Phenotypic Parametersof Some Reproductive Traits of Black Bengal Does
The objective of this study was to evaluate genetic and phenotypic parameters for some reproductive traits of Black Bengal does. Genetic parameters were estimated by Residual Maximum Likelihood procedure, fitting an animal model ignoring maternal genetic or permanent environmental effects. The least-squares means of litter size at birth (LSB), litter size at weaning (LSW), litter weight at birt...
متن کاملGenetic evaluation of Ethiopian Boran cattle and their crosses with Holstein Friesian in central Ethiopia: milk production traits.
Breed additive and non-additive effects, and genetic parameters of lactation milk yield (LYD), 305-day milk yield (305YD), lactation length (LL), milk yield per day of lactation (DM) and lifetime milk yield (LTYD) were estimated in Ethiopian Boran cattle and their crosses with Holstein in central Ethiopia. The data analyzed included 2360 lactation records spread over 15 years. Ethiopian Boran c...
