Abstract

Norwegian Elkhound Grey is used for both leashed and non-leashed tracking. This study provides influence of fixed effects and estimates of genetic parameters of traits related to both types of tracks. In total, 5393 records from 1991 animals tested in the years 1995-2014 on lashed performance (5...

AbstractFull Text

Objectives of the current study were to (i) investigate effects of selection for bodyweight at four weeks old on bodyweight (BW) and bodyweight gain (BWG) across four generations; (ii) estimate correlated response to selection for BW and BWG at different ages; and (iii) document best linear...

AbstractFull Text

This study was carried out to estimate genetic parameters and trends for reproductive performances of Ghezel sheep. The traits included in the analyses were litter size at birth (LSB) and weaning (LSW), and litter mean weight per lamb born (LMWLB) and weaned (LMWLW) as basic traits, and total...

Abstract

Objective. To estimate genetic parameters for weight at eight months of age (W8 M), age at first calving (AFC) and first calving interval (FCI) using pedigree and genomic relationship. Materials and methods. Phenotypic data on 481, 3063 and 1098 animals for W8 M, AFC and FCI were used,...

AbstractFull Text

Phenotypic and genealogy date of Siboney de Cuba cows from 1984 to 2016 calving years was used. The goal of this study was to estimate the parameters and breeding values (VG) of production, reproduction and longevity traits. Besides to construct selection index (IS) using principal componente (CP)...

Abstract

Running multiple breeding programs for the same species requires a high level of investment and management; hence, to date there have not been any attempts to develop specialised genetic lines for different environments in any aquaculture species. This study made the first attempt to conduct a...

Abstract

The aim of the present study was to derive individual methane (CH4) emissions in ewes separated in CH4 respiration and eructation traits. The generated longitudinal CH4 data structure was used to estimate phenotypic and genetic relationships between ewe CH4 records and energy efficiency indicator...
