Lingual haemangiosarcoma in a crossbred dog [PDF]
Irish Veterinary Journal, 2006 An eight-year-old, male neutered, crossbred dog was presented for investigation of a lingual mass of four months duration. Oral examination revealed a 7 cm × 5 cm soft, fluctuant mass at the caudal aspect of the tongue. Ultrasound examination of the mass demonstrated mixed echogenicity, with cavitations containing hypoechoic and anechoic regions ...

Fattening performance and carcass traits of Baladi and Shami-Baladi kids [PDF]
Veterinary World, 2020 Background and Aim: Goat is considered very important ruminant animals that are raised in Jordan; however, the production of the local breeds is low to moderate, and thus, some genetic improvement programs could have a positive effect on the performance ...

Optimal definition of contemporary groups for crossbred pigs in a joint purebred and crossbred genetic evaluation [PDF]
Journal of Animal Science, 2020 Abstract In the pig industry, purebred animals are raised in nucleus herds and selected to produce crossbred progeny to perform in commercial environments. Crossbred and purebred performances are different, correlated traits. All purebreds in a pen have their performance assessed together at the end of a performance test.

A crossbred reference population can improve the response to genomic selection for crossbred performance [PDF]
Genetics Selection Evolution, 2015 Breeding goals in a crossbreeding system should be defined at the commercial crossbred level. However, selection is often performed to improve purebred performance. A genomic selection (GS) model that includes dominance effects can be used to select purebreds for crossbred performance.

Genomic evaluations for crossbred dairy cattle [PDF]
JDS Communications, 2022 This short review discusses genomic evaluations for crossbreed dairy cattle from a New Zealand perspective. I briefly introduce the cow population and farm systems that have resulted in high crossbreeding rates and provide a short history of across-breed genetic and genomic evaluations used in New Zealand since 1996.

Frontiers in Cell and Developmental Biology, 2014 Sub-fertility is one of the most common problems observed in crossbred males, but the aetiology remains unknown in most of the cases. Although proteomic differences in the spermatozoa and seminal plasma between breeds have been investigated, the possible

Journal of Animal Science, 1984 Matings and litters were studied involving all three-breed crosses (sired by purebred boars) and four-breed crosses (sired by cross-bred boars) from the Duroc, Yorkshire, Landrace and Spotted breeds. There were 764 female mating records and 161 boars used over five sequential breeding seasons.
