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 Multi-Breed Genomic Prediction Models for Carcass and Reproductive Traits in Zebu Beef Cattle. [PDF]

Anim Genet
ABSTRACT Genomic prediction in beef cattle is particularly challenging in breeds with limited phenotypic and genotypic data. In this context, multi‐breed methodologies that integrate information from genetically related populations have emerged as a promising strategy to improve prediction accuracy and calibration under data‐scarce conditions.

Strategies For Reducing Age at First Calving in Dairy Animals

, 2023
Raising heifers is one of the most expensive components of the dairy farm operations as they are future of dairy farm. They are produced to replace the older and uneconomical females of the farm through culling. When genetic trends are positive, such replacements help harvest the benefits of genetic gain. Heifer production is most expensive part of the

GENETIC AND PHENOTYPIC TRENDS OF CALVING INTERVAL AND AGE AT FIRST CALVING IN A COMMERCIAL HOLSTEIN HERD [PDF]

Egyptian Journal of Animal Production, 2009
SUMMARY Reproductive records of Holstein cows raised at a commercial farm during the period from 1991 to 2006 were used. A total of 3656 records of 1611 cow daughters of 413 sires and 588 dams were used to study genetic and phenotypic trends of age at first calving (AFC, mo) and calving interval (CI, d).

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

Wildlife Biology, EarlyView.
Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.

Behavioral response of moose Alces alces to summer heat stress

Wildlife Biology, EarlyView.
Minnesota moose are heat‐stressed during summers, which is adversely impacting their survival. We used both movement and activity data to explore the behavioral responses of Minnesota moose experiencing heat stress, termed ‘hot moose events' or HMEs, to understand how both ambient temperature and available habitat contribute to the ability of these ...

REDUCING THE AGE AT FIRST CALVING THROUGH NUTRITIONAL MANIPULATIONS IN DAIRY BUFFALOES AND COWS: A REVIEW [PDF]

Pakistan Veterinary Journal, 2007
Raising heifers is the most expensive component of the dairy farm operations. Poor growth rate resulting in delayed age at maturity in our local dairy animals further aggravates the situation.
