On the progeny-testing of boars in »field conditions»

Agricultural and Food Science, 1968
Kirjoittaja on aikaisemmin (VARO 1967) julkaissut alustavia tutkimustuloksia keinosiemennyskarjujen jälkeläisarvostelujen pysyvyydestä olosuhteissa, joissa jälkeläisryhmät on koottu tavallisissa tuotantosikaloissa kasvatetuista porsaista. Mainituissa tutkimuksissa oli teuraspainot korjattu aineiston keski-ikää ja muiden ominaisuuksien mittaluvut ...

Genetic improvement of cattle through field progeny testing programme: An evaluation of achievement

Indian Journal of Animal Sciences, 2018
Evaluation of bulls through progeny testing and their extensive use has been a major source of genetic improvement in dairy animals. Adequate numbers of progeny tested bulls are not available in India and whatever small numbers of bulls are progeny ...

Evaluation of HF crossbred bulls under field progeny testing programme at different agro-climatic regions in India

Indian Journal of Animal Sciences, 2020
Adequate numbers of progeny tested bulls are not available in India and whatever small number of bulls are progeny tested, they have low repeatability as the progeny tests are based on small number of daughters mostly reared at the institutional farms ...

Performance evaluation and trends estimation of production and reproduction traits in Frieswal cattle under field progeny testing

Indian Journal of Animal Sciences
The objective of animal breeding is to optimize the genetic gain per unit time and to assess this gain per unit time, it is therefore, necessary to separate the environmental component from overall phenotypic gain.

Optimization Strategies to Adapt Sheep Breeding Programs to Pasture-Based Production Environments: A Simulation Study

Animals, 2023
Strong differences between the selection (indoor fattening) and production environment (pasture fattening) are expected to reduce genetic gain due to possible genotype-by-environment interactions (G × E).
