Crossbreeding for Egg Production [PDF]
Poultry Science, 1952 Abstract SEVERAL experiments have been conducted for determining the effect of crossbreeding poultry on rate of growth Most of the investigators seem to be in general agreement that crossbreeding tends to improve growth and hatchability. None of the experiments has been conducted, however, to determine the effect of crossbreeding from the standpoint ...

Estimates of crossbreeding parameters in a multibreed beef cattle crossbreeding project
South African Journal of Animal Science, 2000 Data from purebred and crossbred cattle, consisting of the Afrikaner (A), Simmentaler (S) and Hereford (H) breeds managed in a relatively intensive but high stocking rate environment, were analysed to estimate breed direct effects, individual heterotic effects, breed maternal and maternal heterotic effects for birth weight (BW) and weaning weight (WW).

The effects of breed and gender on meat quality of Duroc, Pietrain, and their crossbred
Journal of Animal Science and Technology, 2020 This study evaluated the effects of breed and gender in Duroc (D), Pietrain (P), and crossbred (DP) pigs. Loin samples were collected from D (n = 79), P (n = 42), and DP (n = 45) pigs. Intramuscular fat content was

Reconstructing pedigrees using probabilistic analysis of ISSR amplification [PDF]
, 2015 Data obtained from ISSR amplification may readily be extracted but only allows us to know, for each gene, if a specific allele is present or not. From this partial information we provide a probabilistic method to reconstruct the pedigree corresponding to

Dynamics of the biodiversity of black and white cattle influenced by cross-breeding
Вавиловский журнал генетики и селекции, 2015 The inter-breed crossing (crossbreeding) permits one to introduce new alleles, extend genetic diversity, and achieve desired phenotypic characteristics of initial breeds. On the other hand, crossbreeding may cause a decrease in genetic differentiation of

Crossbreeding of Yeasts Domesticated for Fermentation: Infertility Challenges
International Journal of Molecular Sciences, 2020 Sexual reproduction is almost a universal feature of eukaryotic organisms, which allows the reproduction of new organisms by combining the genetic information from two individuals of different sexes.

Carcass characteristics of cattle differing in Jersey proportion [PDF]
, 2018 peer-reviewedComparison of alternative dairy (cross-)breeding programs requires full appraisals of all revenues and costs, including beef merit. Few studies exist on carcass characteristics of crossbred dairy progeny originating from dairy herds as well ...

Cattle crossbreeding for sustainable milk production in the tropics
International Journal of Livestock Production, 2020 Crossbreeding has been used to improve milk production performance of local cattle in the tropics. Crossbreeding exploits additive and non-additive allele gene effects leading to improvements in lactation length, decrease in calving interval, higher milk
