Mass transfer in beef: effect of crossbreeding and ultrasound application
Cuts of muscle (biceps femoris) from three crossbreeds between the Nelore, Angus and Wagyu breeds of cattle (Crossbreed 1 (C1): 1⁄2 Angus and 1⁄2 Nelore; Crossbreed 2 (C2): 3⁄4 Angus and 1⁄4 Nelore; Crossbreed 3 (C3): 1⁄2 Wagyu, 1⁄4 Nelore and 1⁄4 Angus)

Using three-breed rotational crossbreeding in a purebred Holstein (HO) herd raises two questions: Do the different genetic classes of cows generated by crossbreeding perform differently?

Farmers play a key role in conserving native livestock breeds, but without economic support, farms with native breeds may not be viable. We hypothesized that terminal crossbreeding can improve herd economy and decrease the economic support needed from ...

Genomic analyses provide insights into breed-of-origin effects from purebreds on three-way crossbred pigs [PDF]
Crossbreeding is widely used aimed at improving crossbred performance for poultry and livestock. Alleles that are specific to different purebreds will yield a large number of heterozygous single-nucleotide polymorphisms (SNPs) in crossbred individuals ...

Smallholder experiences with dairy cattle crossbreeding in the tropics: from introduction to impact
Crossbreeding of indigenous tropical and improved western dairy cattle breeds as tool to improve dairy cattle performance on smallholder farms has been widely advocated, criticised and yet applied. The government of Ethiopia supported this technology for

Comparative study of lactation curves and milk quality in Holstein versus Swedish Red and White-Holstein Cross Cows [PDF]
The objective of this study reported in this research paper was to compare the lactation curves of the production of milk, fat, protein, percentages of fat and protein, and somatic cell score in purebred Holstein (H) cows and Swedish Red and White (SRW) -

Biological compatibility between two temperate lineages of brown dog ticks, Rhipicephalus sanguineus (sensu lato) [PDF]
Background: The brown dog tick Rhipicephalus sanguineus (sensu stricto) is reputed to be the most widespread tick of domestic dogs worldwide and has also been implicated in the transmission of many pathogens to dogs and humans.

Economic opportunities of using crossbreeding and sexing in Holstein dairy herds.
With the increasing availability of sexed semen, farms have the opportunity to select genetically superior dams to produce their replacement animals and to produce crossbred calves for beef production of higher economic value than the remainder of the ...

Using sexed semen to produce purebred replacement heifers makes it possible to mate a large proportion of dairy cows to double-muscled sires and to quantitatively and qualitatively improve beef production and increase the income from dairy herds.

Breed, heterosis, and recombination effects for lactation curves in Brazilian cattle
The objective of this study was to estimate the breed, heterosis, and recombination effects on different components of the lactation curve of Girolando cattle. The dataset used consisted of 12,121 purebred cows of Holstein (H) and Gyr (G) breeds, and six
