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

Parturition timing and the pre‐ and post‐partum behaviour of female moose assessed using animal‐borne video and movement‐based approaches

Wildlife Biology, EarlyView.
Limited information on moose calving behaviour, including parturition timing, cow‐calf interactions, and pre‐ and post‐partum movement patterns hinder our ability to define calving phenology and habitat use. GPS‐collars were deployed on 89 female moose over five years, including eight collars equipped with animal‐borne video and environmental data ...

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.

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.

In pursuit of just elephant management: Making a case for legal reform

Wildlife Society Bulletin, EarlyView.
Abstract Elephant management in South Africa remains entangled in legal, ethical, and ecological complexity. Despite the adoption of the 2008 Norms and Standards for Elephant Management and the 2016 Norms and Standards for the Management of Damage‐Causing Animals in South Africa, governance and management challenges persist across fenced reserves, open

Season of birth is associated with first-lactation milk yield in Holstein Friesian cattle

Animal, 2017
The aim of the present research was to assess factors associated with first-lactation milk yield in dairy heifers, including maternal and environmental factors, factors related to the development of the heifer and factors related to its offspring such as

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

Journal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds

Journal of Animal Ecology, EarlyView.
Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...
