Identification of novel nucleotide sequence variations in an extended region of the bovine leptin gene (LEP) across a variety of cattle breeds from New Zealand and Nigeria
(Copernicus Publications on behalf of Leibniz Institute for Farm Animal Biology (FBN), 2020-07-22)Leptin is mainly secreted by white adipose tissue in animals. Leptin acts by stimulating or inhibiting the release of a neurotransmitter, which eventually results in a decrease in food/feed intake and an increase in energy ... -
Variation in the stearoyl-CoA desaturase gene (SCD) and its influence on milk fatty acid composition in late-lactation dairy cattle grazed on pasture
(Copernicus Publications on behalf of the Leibniz Institute for Farm Animal Biology (FBN), 2020-11-03)Gene markers have become useful tools for improving animal genetics and breeding since they improve the accuracy of selection for superior breeding stock. In this study, the stearoyl-CoA desaturase (Δ-9-desaturase) gene ... -
The Happy Factor treatment threshold, used to determine Targeted Selective Treatment decisions for lambs, is transferable between farms
(Elsevier on behalf of the Animal Consortium, 2021-02-13)Weight gain-based treatment decision-making has been shown to successfully reduce the number of anthelmintic treatments without compromising production as part of a Targeted Selective Treatment (TST)-based worm control ... -
Investigation into udder characteristics, mastitis and milk production in crossbred sheep
(New Zealand Society of Animal Production (Inc), 2018)Associations between udder characteristics, milk yield, milk somatic cell counts (SCC) and prevalence of mastitis were evaluated in 121 twin-suckled crossbred non-dairy ewes at four, eight and twelve weeks after parturition. ... -
Supplementation of ewes on pasture to provide an epidemiological benefit for gastrointestinal parasitism
(New Zealand Society of Animal Production (Inc), 2018)The potential epidemiological benefit of reducing the peri-parturient relaxation in immunity to gastro-intestinal nematode parasites through supplementing twin-bearing ewes during the first four weeks of lactation was ...
