“…Contrary to the present findings, Dall'Olio et al (2013) reported that SNPs in BMPR1B, FUT1, GPX5, RBP4 and TGFBR1 genes showed significant association (P<0.003) with NBA (number of piglets born alive at first parity), EBVs (estimated breeding values for the number of piglets born alive at first parity) in Italian Large White purebred sows. In addition, Gondim et al (2019) analyzed significant associations between MC4R, FABP3, and DGAT1 genes polymorphisms and the reproductive traits in pigs (Large White x Landrace Danish).…”

Aim: To detect genetic variants of GPX5 gene and their associations with reproductive and productive traits in the Lumsniang (Hampshire x Niang Megha) pigs. Methodology: In this study, a total of 87 Lumsniang pigs were selected for collecting blood samples (3-5 ml) from Nucleus Pig Breeding Farm of ICAR Research Complex for North Eastern Hilly region, Umiam, Meghalaya. Genomic DNA was extracted from the blood leukocytes using the Qiagen DNeasy Blood and tissue kits and diluted to working concentration (50 ng μl-1) and stored at -20°C, which were used as templates for association of GPX5 variants with polymerase chain reaction. The data for reproductive and productive traits were recorded from all the animals taken in this study. The reproductive and productive traits were analyzed using a general linear model (GLM) procedure of SPSS Version 16.0. Results: Polymorphisms at Intron 1 of the GPX5 gene was determined by PCR-RFLP with HinfI restriction enzyme and DNA sequencing analyses. Two alleles and three genotypes were identified by HinfI digestion of the GPX5 gene. In the SNP-HinfI (g.1896A>G) locus, significant associations were found between GPX5 genotypes and litter size at birth. The genotype AA demonstrated significantly (P<0.05) superior litter size at birth as compared to AG and GG genotypes at the SNP-HinfI locus in Lumsniang pig. Interpretation: The study reported probable associations of GPX5 variants with reproduction and production traits in Lumsniang pig. The genotype AA at locus SNP-HinfI improved the litter size at birth in the studied population. The GPX5 gene may be considered as a DNA marker for marker-assisted selection after validation in a large pig population.

“…Pig farming productivity and profitability are influenced by sow reproductive efficiency (measured in piglets weaned per sow per year) (Dall'Olio et al, 2013). Improvements in sow reproductive performance are slow in porcine production due to low heritability of reproductive traits (Goddard and Hayes, 2009;Bidanel, 2011).…”

Recent developments in cattle, pig, sheep and horse breeding - a review

et al. 2014

View full text Add to dashboard Cite

The aim of this review was to summarize new genetic approaches and techniques in the breeding of cattle, pigs, sheep and horses. Often production and reproductive traits are treated separately in genetic evaluations, but advantages may accrue to their joint evaluation. A good example is the system in pig breeding. Simplified breeding objectives are generally no longer appropriate and consequently becoming increasingly complex. The goal of selection for improved animal performance is to increase the profit of the production system; therefore, economic selection indices are now used in most livestock breeding programmes. Recent developments in dairy cattle breeding have focused on the incorporation of molecular information into genetic evaluations and on increasing the importance of longevity and health in breeding objectives to maximize the change in profit. For a genetic evaluation of meat yield (beef, pig, sheep), several types of information can be used, including data from performance test stations, records from progeny tests and measurements taken at slaughter. The standard genetic evaluation method of evaluation of growth or milk production has been the multi-trait animal model, but a test-day model with random regression is becoming the new standard, in sheep as well. Reviews of molecular genetics and pedigree analyses for performance traits in horses are described. Genome -wide selection is becoming a world standard for dairy cattle, and for other farm animals it is under development.
