A total of 125 Russian Red Pied cows were genotyped for the prolactim-related gene. The PRL-RsaI genotypes were analysed using the Polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) method. In this breed, the frequencies of alleles were as follows;  A= 0.794 and B= 0.206. The frequencies of AA, AB and BB genotypes were 0.598, 0.392 and 0.01; respectively. Results sho...

in this research, 272977 test day records collected from 659 herds during years 2001 to 2011 by the iranian animal breeding center were used. in the first section the ability of different models to predict daily milk yield from alternative milk recording was tested. the result showed that a complex model including noon milking time plus the effect of lactation curve of ali and schaeffer functio...

soy protein concentrate (spc) is a functional and nutritional product which is produced under conditions where soy proteins are immobilized in soy flour and soluble carbohydrates are removed. in this study, four different soy flours including defatted soy flour (fat content 3.67, pdi 55.10), defatted and toasted soy flour (fat content 3.78, pdi 10.72), low fat soy flour (fat content 14.34, pdi ...

________________________________________________________________________________ Abstract The effect of inbreeding on the 305-d yields of milk, fat and protein, and the percentages of fat and protein in the first three lactations was estimated using records on the South African Jersey cows that participated in the National Dairy Animal Improvement Scheme. Inbreeding coefficients were estimated ...
