Balanced selection on purebred and crossbred performance increases gain in crossbreds [PDF]
Genetics Selection Evolution, 2018 Genomic selection can be applied to select purebreds for crossbred performance (CP). The average performance of crossbreds can be considered as the summation of two components, i.e. the breed average (BA) of the parental breeds and heterosis (H) present in crossbreds.

Evaluation and comparison of the constitutive expression levels of Toll-like receptors 2, 3 and 7 in the peripheral blood mononuclear cells of Tharparkar and crossbred cattle [PDF]
Veterinary World, 2014 Aim: This study was undertaken to assess the differential expression levels of toll-like receptors (TLRs) 2, 3 and 7 in peripheral blood mononuclear cells (PBMCs) isolated from Tharparkar and Crossbred cattle belonging to different regions of India ...

Basal body temperature as a biomarker of reproductive state in ewes: A multi-method comparison. [PDF]
Aust Vet JThis study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...

Journal of Dairy Science, 2022 Culled dairy cows represent a considerable source of meat production, but their carcasses may vary greatly in quality because of the wide variation in the age, stage of lactation, breed, body condition, and other characteristics of the cows at slaughter.

Gastroschisis-Like Defect in a Crossbred Bovine Calf: Anatomical, Clinical and Surgical Perspectives. [PDF]
Vet Med SciA gastroschisis‐like defect was observed in a one‐day‐old, crossbred bovine calf with evisceration of the pyloric abomasum and small intestine, likely resulting from prenatal rupture of an omphalocele. The calf presented with lethargy, hypothermia and metabolic derangements, along with elevated renal biomarkers.

Breed of origin of alleles and genomic predictions for crossbred dairy cows
Genetics Selection Evolution, 2021 In dairy cattle, genomic selection has been implemented successfully for purebred populations, but, to date, genomic estimated breeding values (GEBV) for crossbred cows are rarely available, although they are valuable for rotational crossbreeding schemes
