Artificial infestation of Boophilus microplus in beef cattle heifers of four genetic groups

Genetics and Molecular Biology, 2007
Resistance of beef cattle heifers to the cattle tick Boophilus microplus was evaluated by artificial infestation of 66 beef cattle heifers of the following genetic groups: 16 Nelore (NE), 18 Canchim x Nelore (CN), 16 Angus x Nelore (AN) and 16 Simmental ...

Metabolomics Reveals that Crossbred Dairy Buffaloes Are More Thermotolerant than Holstein Cows under Chronic Heat Stress.

Journal of Agricultural and Food Chemistry, 2018
Heat stress (HS) threatens the worldwide dairy industry by decreasing animal production performance and health. Holstein cows and dairy buffaloes are the most important dairy animals, but their differences in the metabolic mechanism of thermotolerance ...

Sensorial and nutritional qualities of muscles from cross‐bred Salers heifers raised on mid‐mountain pasture

JSFA reports, EarlyView.
Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...

Genome-wide association study for carcass quality traits and growth in purebred and crossbred pigs.

Journal of Animal Science, 2019
Carcass quality traits such as backfat (BF), loin depth (LD), and average daily gain (ADG) are of extreme economic importance for the swine industry. This study aimed to: i) estimate the genetic parameters for such traits and ii) conduct a single-step ...

Health treatment cost, stillbirth, survival, and conformation of Viking Red-, Montbéliarde-, and Holstein-sired crossbred cows compared with pure Holstein cows during their first 3 lactations.

Journal of Dairy Science, 2020
Three generations of crossbreds from a 3-breed rotation of the Viking Red (VR), Montbéliarde (MO), and Holstein (HO) breeds were compared with their HO herdmates in 7 commercial dairy herds in Minnesota.

Genome-Wide SNP Data Revealed the Extent of Linkage Disequilibrium, Persistence of Phase and Effective Population Size in Purebred and Crossbred Buffalo Populations

Frontiers in Genetics, 2019
Linkage disequilibrium (LD) is a useful parameter for guiding the accuracy and power of both genome-wide association studies (GWAS) and genomic selection (GS) among different livestock species. The present study evaluated the extent of LD, persistence of

The nature of the purebred-crossbred genetic covariance

Genetical Research, 1971
SUMMARYEpistatic models are examined for conditions which result in a negative covariance between a sire's purebred and test-cross progenies. It is found that heterozygote superiority is not a necessary condition for its occurrence. The frequencies of the same allele in the selected population and in the tester should be divergent.

Epidemiological distribution of MRI‐based presumptive imaging diagnoses in a large general population of cats with suspected epileptic seizures

Veterinary Record, EarlyView.
Abstract Background The reported prevalence of feline idiopathic epilepsy (IE) and presumptive imaging diagnoses based on magnetic resonance imaging (MRI) varies depending on factors such as differences between primary care versus referral study populations.
