Expression profiles of growth-related genes in two Nile tilapia strains and their crossbred provide insights into introgressive breeding effects.

Anim Genet 2020 May 7. Epub 2020 May 7.

Department of Genetics, Institute of Biosciences of Botucatu, São Paulo State University (UNESP), Botucatu, SP, 18618-689, Brazil.

The Nile tilapia (Oreochromis niloticus) is a prominent farmed fish in aquaculture worldwide. Crossbreeding has recently been carried out between the Red-Stirling and the wt Chitralada strains of Nile tilapia, producing a heterotic hybrid (7/8 Chitralada and 1/8 Red-Stirling) that combines the superior growth performance of the Chitralada with the reddish coloration of the Red-Stirling strain. While classical selective breeding and crossbreeding strategies are well known, the molecular mechanisms underlying the phenotypic expression of economically advantageous traits in tilapia remain largely unknown.

Heteropaternal superfecundation frequently occurs in multiple-bearing mob-mated sheep.

Anim Genet 2020 Apr 28. Epub 2020 Apr 28.

Sheep Ireland, Highfield House, Shinagh, Bandon Co. Cork, P72 X050, Ireland.

Heteropaternal superfecundation may be defined as the fertilisation of two or more ova during the same oestrus cycle as a result of more than one coital act from different males; this results in foetuses being born in the same litter of the same age but different paternity. Heteropaternal superfecundation is more likely to occur in poly-ovulatory species like sheep; moreover, female sheep are often mob-mated with several rams concurrently, thus providing an opportunity for a given female to be served by multiple males during the same oestrus cycle. The objective of the present study was to determine the frequency of heteropaternal superfecundation in six sheep flocks where most of the ewes, lambs and rams were genotyped. Read More

Colour-sidedness in Gloucester cattle is associated with a complex structural variant impacting regulatory elements downstream of KIT.

Anim Genet 2020 Jun 12;51(3):461-465. Epub 2020 Apr 12.

Unit of Animal Genomics, GIGA Institute, University of Liège, 1, avenue de l'hôpital, Liège, 4000, Belgium.

Colour-sidedness is a striking coat colour pattern found in a number of cattle breeds, typically characterised by a white stripe that extends along the back, head and belly of the animal. This dominant phenotype is caused by two related translocations (Cs and Cs ) that alter a region downstream of the KIT gene. Gloucester cattle are native to the UK and are known for an unusual colour-sided pattern that does not extend to the head. Read More

In genomic selection (GS), genome-wide SNP markers are used to generate genomic estimated breeding values for selection candidates. The application of GS in shellfish looks promising and has the potential to help in dealing with one of the main issues currently affecting Pacific oyster production worldwide, which is the 'summer mortality syndrome'. This causes periodic mass mortality in farms worldwide and has mainly been attributed to a specific variant of the ostreid herpesvirus (OsHV-1). Read More

We detected growth-related QTL and associated markers from the backcross population of Exopalaemon carinicauda in the previous study. Based on our previous study, the 47 SNP markers associated with candidate growth trait QTL were selected to analyze the association between these markers and body weight (BW), body length and abdominal segment length traits in four different populations including wild population, a full-sib family, a half-sib family and a backcross population for evaluating their potential application of marker-assisted selection in E. carinicauda.

Selection for performance in diverse production settings has resulted in variation across sheep breeds worldwide. Although sheep are an important species to the United States, the current genetic relationship among many terminal sire breeds is not well characterized. Suffolk, Hampshire, Shropshire and Oxford (terminal) and Rambouillet (dual purpose) sheep (n = 248) sampled from different flocks were genotyped using the Applied Biosystems Axiom Ovine Genotyping Array (50K), and additional Shropshire sheep (n = 26) using the Illumina Ovine SNP50 BeadChip.

The domestic Asian water buffalo (Bubalus bubalis) is found on all five continents, with a global population of some 202 million. The livelihoods of more people depend on this species than on any other domestic animal. The two distinct types (river and swamp) descended from different wild Asian water buffalo (Bubalus arnee) populations that diverged some 900 kyr BP and then evolved in separate geographical regions.

Some livestock breeds face the challenge of reduced genetic variation, increased inbreeding depression owing to genetic drift and selection. Hybridization can reverse these processes and increase levels of productivity and adaptation to various environmental stressors. Samples from American Brangus were used to evaluate the indicine/taurine composition through nine generations (~45 years) after the hybridization process was completed. Read More
