Genetic and Non-genetic Factors Affecting Some Reproduction Traits in Tharparkar Cattle
A total of 1385 lactation records of Tharparkar cattle collected from LRS Chandan, Jaisalmer spreading over a period of 33 years were utilized to assess the effects of period and season of birth/calving on age at first calving, calving interval and service period and also studied effect of parity on calving interval and service period. The least-squares means were 1821.86 ± 37.022 days, 414.16 ...
متن کاملNon-Genetic Factors Affecting Grasscutter Production Traits. 1. Growth Traits
This study was conducted at the grasscutter section of the University of Education, Winneba, Ghana, to estimate effects of non-genetic factors on growth traits. Data consisted of records of 502 kids born from 136 does and 40 sires from 2006 to 2010. Feed intake increased (P<0.01) with increasing parity and years, whilst feed efficiency declined (P<0.01) with years. Animals consumed less (P<0.01...
متن کاملGenetic variants affecting meat and milk production traits appear to have effects on reproduction traits in cattle.
Polymorphisms located in the genes ABCG2, DGAT1, LEP, PRLR, RORC, CAPN1 and CAST previously have been associated with milk or meat production traits. In this study, these polymorphisms were examined for significant effects on reproductive traits [age at puberty (AGECL), post-partum anoestrus interval (PPAI) and the ability ovulate prior to weaning (PW)] and on a panel of correlated traits such ...
متن کاملQuantitative trait loci affecting fertility and calving traits in Swedish dairy cattle.
Impaired fertility is the main reason for involuntary culling of dairy cows in Sweden. The objective of this study was to map quantitative trait loci (QTL) influencing fertility and calving traits in the Swedish dairy cattle population. The traits analyzed were number of inseminations, 56-d nonreturn rate, interval from calving to first insemination, fertility treatments, heat intensity score, ...
متن کاملGenome scan detects quantitative trait loci affecting female fertility traits in Danish and Swedish Holstein cattle.
Data from the joint Nordic breeding value prediction for Danish and Swedish Holstein grandsire families were used to locate quantitative trait loci (QTL) for female fertility traits in Danish and Swedish Holstein cattle. Up to 36 Holstein grandsires with over 2,000 sons were genotyped for 416 microsatellite markers. Single trait breeding values were used for 12 traits relating to female fertili...
