Genetics of crossbred sow longevity
The aim of this study was to estimate genetic parameters for longevity from Swedish crossbred sows to investigate the possibilities of selecting for this trait. Data were collected from 16 commercial piglet-producing herds, on crossbred (Landrace × Yorkshire) sows farrowing in the period 1 January 2001 to 31 December 2004.

As crossbreeding is extensively used in some livestock species, we aimed to evaluate the performance of single-step GBLUP (ssGBLUP) and weighted ssGBLUP (WssGBLUP) methods to predict Genomic Estimated Breeding Values (GEBVs) of crossbred animals ...

Relationship between heterosis, weight gain, and body measurements of Nellore and Charolais calves [PDF]
: The objective of this work was to assess the effect of genetic group and heterosis on the relationship between body weight and morphometric measurements, in purebred and crossbred animals from the second (G2) and third (G3) generations of Nellore and ...

The cost of SNP genotyping to screen different breeds and to estimate the exact proportion of ancestry level, is quite high which can be compensated through deriving a small panel of ancestry informative markers (AIMs).

GENETIC AND ENVIRONMENTAL EFFECTS- ON DOE REPRODUCTIVE PERFORMANCE UNDER DESERT CONDITION [PDF]
Reproductive performance of 215 does of pure New Zealand Wbite·1abbits (NN), pure Californian (CC), two reciprocal crosses (NC& CN), two backerosses (BCN and BCe) and F2 crossbred were studied.

Introduction In Northeast China, Dorper and Australian White rams are commonly crossbred with small-tailed Han (STH) ewes to improve the offspring's meat yield and quality. However, the differences in traits and the flavor between the crossbred sheep and

Genomic selection of purebreds for crossbred performance [PDF]
Abstract Background One of the main limitations of many livestock breeding programs is that selection is in pure breeds housed in high-health environments but the aim is to improve crossbred performance under field conditions.
