Effect of improving management system on camel milk production [PDF]
, 2015 Twenty four lactating she-Camels of the Sudanese Kabbabish breed and were divided into two equal groups of 12 animals. The first group was managed in a semi intensive system by offering concentrates and roughage, free access to water and veterinary care.

Effects of pregnancy on daily milk yield of Holstein–Friesian dairy cattle
Livestock Production Science, 2004 First, second and third lactation curves of 21,885 first lactation dairy cows were allowed to vary depending on the months in milk at which the cow became pregnant. The curves were modelled using a 4th degree polynomial of days in milk. In the models for second and third lactation daily yield, days open in the previous lactation was included as a ...

The Effect of Neighbouring Cows within the Milking Parlour on a Cow's Daily Milk Yield
Livestock ScienceSocial interactions in a dairy herd are essential to maintain the herd's structure. Disturbances in social relationships can be stressful and may impact both animal welfare and production. Pathological and physiological changes, biological variations, but also the social environment induced by surrounding cows can affect variation in the daily milk ...

Comparison of statistical models to estimate daily milk yield in single milking testing schemes
Italian Journal of Animal Science, 2005 Different statistical models were compared to estimate daily milk yield from morning or evening milking test results. The experiment was conducted on 14 family farms with 325 recorded cows. The amount of explained variance was higher for models including the effects of partial milk yield, the interval between successive milking, the interaction between
