Variances of direct genetic effects, maternal genetic effects, and cytoplasmic inheritance effects for milk yield, fat yield, and fat percentage.
Milk yield, fat yield, and fat percentage during the first three lactations were studied using New York Holsteins that were milked twice daily over a 305-d, mature equivalent lactation. Those data were used to estimate variances from direct and maternal genetic effects, cytoplasmic effects, sire by herd interaction, and cow permanent environmental effects. Cytoplasmic line was traced to the las...
متن کاملGenetic parameters for test-day yield of milk, fat and protein in buffaloes estimated by random regression models.
The test-day yields of milk, fat and protein were analysed from 1433 first lactations of buffaloes of the Murrah breed, daughters of 113 sires from 12 herds in the state of São Paulo, Brazil, born between 1985 and 2007. For the test-day yields, 10 monthly classes of lactation days were considered. The contemporary groups were defined as the herd-year-month of the test day. Random additive genet...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Investigation of Non-Genetics Factors Affecting Milk-Fat Content and Milk-Fat Percentage Curves' Parameters In Azeri and Khuzestani Buffalo Breeds
The study of milk production and composition curves in buffalo provides key information about genetic potentials and management related strategy to both breeders and farmers. The objective of this study was to identify of the non-genetic factors of parameters for fitted Wood function on milk fat content (MFC) and milk fat percentage (MFP) curve of Azari and Khuzestan buffalo. The data were...
