An all-breed animal model was developed for routine genetic evaluations of US dairy cattle. Data sets from individual breeds were combined, and records from crossbred cows were included. About 1% of recent cows were first-generation crossbreds. The numbers of cows with records since 1960 ranged from 10 to 22 million for the 6 traits analyzed, which were milk, fat, protein, somatic cell score, p...

Cashmere is only produced from Maraz (Kurdi) goat breed in Iraqi Kurdistan Region. The objective of this study was to assess the genetic diversity of different Maraz color types, black goat and Shami breeds using random amplified polymorphic DNA (RAPD) markers. Fourteen primers were used and nine out of them were selected based on their number of bands (NB) and polymorphic characteristics. Thes...

Brix and apparent purity are well known to be biased estimators of dry solids and true purity respectively, particularly on lower purity streams. Correlations which estimate dry solids from brix and apparent purity and estimate true purity also from brix and apparent purity are presented. The suitability of these correlations is evaluated in the light of available historical data.

After more than thirty years in private practice, I realize the majority of canine ocular diseases have a breed predisposition. This talk will reflect the most common inherited corneal and scleral diseases in the breeds seen in my practice. It is pertinent to keep in mine, the breed incidence may reflect just the popularity of the breed. Also just as certain lines in a breed may have different ...

BACKGROUND The effect of breed on Porcine Reproductive and Respiratory Syndrome Viremia (PRRSV) was tested using data collected in 17 Italian commercial pig farms and 1096 genotypes obtained by the PorcineSNP60 BeadChip. A binomial logistic model was used to investigate the relationship between breed-clusters and PRRSV susceptibility. Breed-clusters were defined using the matrix of genomic kins...

A model for comparing resistance to Salmonella Enteritidis was evaluated in different broiler breeds. The recruitment and phagocytic activity of peritoneal macrophages were assessed in three different broiler breeds (A, B and C) which are farmed world-wide. Assessment was performed after three days of intraperitoneal (i.p.) administration of 3% Sephadex G-200 (10 ml), initiated at twenty-one da...

Information from a reference population of animals with accurate breeding values is used to predict the genetic merit test for which such phenotypic information not available. For crosses, these procedures may be proportion genes one breed in crossbred cattle when sets genotypes purebred are available as reference. The genomic composition 6326 HF (as population) performing Gujarat was determine...
