Journal of Veterinary Medical Research, 2009 A retrospective study including reproductive and productive data of 1587 primiparous Holstein cows covering a period of eight years. The reproductive data ( interval to 1st service, service period, days open, number of inseminations per conception and ...

Genetic relationships between calving date, calving interval, age at first calving and type traits in beef cattle [PDF]
, 2011 In this paper the genetic relationships between major reproductive traits in beef cattle (Calving Date, Calving Interval and Age at First Calving) and type traits have been estimated to evaluate the usefulness of type classification in predicting ...

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.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ungulate body fat reserves reflect the nutritional environment, often serving as a useful indicator of bottom‐up resource availability. However, body fat reserves also integrate energetic costs associated with avoiding predation risk and reproductive effort, and it is ...

EFFECTS OF DIET SUPPLEMENTATION WITH ANIONIC SALTS ON BREEDING PERFORMANCE OF DAIRY COW
Agricultura, 2018 This research proves the effects of Calving Care on reproductive performance in dairy cow, during three successive lactations, on a group of 10 Holstein Friesian cows, using the method of period research.

Finite Element Analysis of Small Scale Continuous Calving [PDF]
, 2013 Ice shelves are floating ice masses, which are sensitive to climate changes. The main mechanisms for the mass loss of ice shelves around Antarctica are basal melting and calving.

Genome-wide association study for calving performance using high-density genotypes in dairy and beef cattle [PDF]
, 2015 peer-reviewedBackground Calving difficulty and perinatal mortality are prevalent in modern-day cattle production systems. It is well-established that there is a genetic component to both traits, yet little is known about their underlying genomic ...

Journal of Animal Ecology, EarlyView.The authors distil how dimensions of biodiversity drive ecosystem processes with increasing temperature. Specifically, species physiology more greatly affected ecosystem primary production than did foraging behaviour, and physiology mediated non‐additive interactions with temperature.
