Background Crossbreeding is widely used in pig production because of the benefits of heterosis effects and breed complementarity. Commonly, sire lines are bred for traits such as feed efficiency, growth and meat content, whereas maternal lines are also ...

Estimation of dominance variance in purebred Yorkshire swine. [PDF]
We used 179,485 Yorkshire reproductive and 239,354 Yorkshire growth records to estimate additive and dominance variances by Method Fraktur R. Estimates were obtained for number born alive (NBA), 21-d litter weight (LWT), days to 104.5 kg (DAYS), and backfat at 104.5 kg (BF).

Andrological characterisation of Chilean purebred stallions [PDF]
Chilean purebred horses are widely used in Chile for rodeo and farm work. Despite the importance of the breed, systematic studies characterising their andrological variables are lacking, making stallion evaluation and selection difficult. This study aimed to determine whether age and seasonality affect seminal, spermatic, gonadal and endocrine ...

Abstract Background Symmetric dimethylarginine (SDMA) is a biomarker of renal function derived from arginine methylation, unaffected by muscle mass or diet, and increases after only a 25% reduction in renal function, allowing earlier detection of renal dysfunction compared with serum creatinine.

Genetic analysis of the Sicilian Oriental Purebred horse
Sicilian Oriental Purebred is a small breed considered at critical risk status. In order to evaluate the genetic diversity of the extant selection nucleus, two different molecular markers were used. Twelve microsatellite loci were characterized to assess

Abstract Background Extreme cephalic conformation has been theorised to be associated with compromised health in rabbits. However, recognition and assessment of such phenotypes remain largely subjective. This study aimed to develop and validate a visual, semi‐quantitative system for head shape phenotype in rabbits.

Maximizing crossbred performance through purebred genomic selection [PDF]
In livestock production, many animals are crossbred, with two distinct advantages: heterosis and breed complementarity. Genomic selection (GS) can be used to select purebred parental lines for crossbred performance (CP). Dominance being the likely genetic basis of heterosis, explicitly including dominance in the GS model may be an advantage to select ...

Shared struggles: Parallels in caregiver burden between canine and paediatric epilepsy
Abstract Background Disease‐specific aspects of pet owners’ caregiver burden could be missed by generic burden measures. This study aimed to assess whether a framework developed to describe caregiver burden in parents of children with epilepsy was applicable to caregivers of dogs with epilepsy.

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.
