Heritability and genetic correlation estimates of semen production traits with litter traits and pork production traits in purebred Duroc pigs [PDF]

Journal of Animal Science, 2022
AbstractWe estimated heritabilities of semen production traits and their genetic correlations with litter traits and pork production traits in purebred Duroc pigs. Semen production traits were semen volume, sperm concentration, proportion of morphologically normal sperms, total number of sperm, and total number of morphologically normal sperm.

Bacteriocin Production: a Probiotic Trait? [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Bacteriocins are an abundant and diverse group of ribosomally synthesized antimicrobial peptides produced by bacteria and archaea. Traditionally, bacteriocin production has been considered an important trait in the selection of probiotic strains, but until recently, few studies have definitively demonstrated the impact of bacteriocin

Quantitative Trait Loci Affecting Milk Production Traits in Finnish Ayrshire Dairy Cattle [PDF]

Journal of Dairy Science, 2003
A whole genome scan of Finnish Ayrshire was conducted to map quantitative trait loci (QTL) affecting milk production. The analysis included 12 half-sib families containing a total of 494 bulls in a granddaughter design. The families were genotyped with 150 markers to construct a 2764 cM (Haldane) male linkage map.

Key canopy traits drive forest productivity [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2012
Quantifying the mechanistic links between carbon fluxes and forest canopy attributes will advance understanding of leaf-to-ecosystem scaling and its potential application to assessing terrestrial ecosystem metabolism. Important advances have been made, but prior studies that related carbon fluxes to multiple canopy traits are scarce. Herein, presenting

N2O production, a widespread trait in fungi [PDF]

Scientific Reports, 2015
AbstractN2O is a powerful greenhouse gas contributing both to global warming and ozone depletion. While fungi have been identified as a putative source of N2O, little is known about their production of this greenhouse gas. Here we investigated the N2O-producing ability of a collection of 207 fungal isolates.

Identification of Quantitative Trait Loci for Production Traits in Commercial Pig Populations [PDF]

Genetics, 2003
Abstract The aim of this study was to investigate methods for detecting QTL in outbred commercial pig populations. Several QTL for back fat and growth rate, previously detected in experimental resource populations, were examined for segregation in 10 different populations.

Multitrait Quantitative Trait Loci Mapping for Milk Production Traits in Danish Holstein Cattle [PDF]

Journal of Dairy Science, 2006
The aims of this study were (1) to confirm previously identified quantitative trait loci (QTL) on bovine chromosomes 6, 11, 14, and 23 in the Danish Holstein cattle population, (2) to assess the pleiotropic nature of each QTL on milk production traits by building multitrait and multi-QTL models, and (3) to include pedigree information on nongenotyped ...

Climatic Effects on Productive Traits in Livestock

Veterinary Research Communications, 2006
Each species, breed or animal category has its own thermal zone of comfort outside of which it experiences heat stress in the attempt to maintain homeothermy, so that less energy is available for production processes. Cold represents less of a problem than heat.

Relation of Production Traits and Reproduction Traits in Swine

Journal of Animal Science and Technology, 2007
In order to investigate the relation of production traits and reproduction traits the data from Gyungnam heugdon(Berkshire) were analyzed. Pearson correlation coefficients of the reproductive traits including days to first farrowing, days to first breeding and no. of breeding for first litter with back fat thickness were ranged -.24 to -.26.

The fat and protein content of the sheep milk under different conditions [PDF]

, 2000
In Hungary the Hungarian Combing Merino has been and still is the most common sheep breed. In order to increase the milk production traits, especially the milk components, several crossings were made.
