Assessment of Feed Quality by Non-destructive Methods
Scientific Papers Animal Science and Biotechnologies, 2023 For the optimal optimization of feed ration, it is crucial to assess the quality of the forage feed to dairy cows. To have a good production of milk and meat on a cattle farm, the farmers must collaborate with the nutrition and feed control laboratories ...

Development of Cika cattle breed
Acta agriculturae Slovenica. Suplement, 2012 Cika cattle is the only Slovenian autochthonous cattle breed. It originates from Bohinj where breeders bred their own »cow families« and by doing so they kept a relatively high milk yield of Bohinj cows. They did not buy cows outside of Bohinj, only the bulls were purchased by the cooperatives at the cattle breeding fairs. Cika cattle was a widely used

Estimating test-day milk yields by modeling proportional daily yields: Going beyond linearity
Journal of Dairy Science, 2023 : In the United States, lactation milk yields are not measured directly but are calculated from the test-day milk yields. Still, test-day milk yields are estimated from partial yields obtained from single milkings.

Journal of Animal Science and Biotechnology, 2019 Background Fatty acids are important traits that affect meat quality and nutritive values in beef cattle. Detection of genetic variants for fatty acid composition can help to elucidate the genetic mechanism underpinning these traits and promote the ...
