The Effect of Neighbouring Cows within the Milking Parlour on a Cow's Daily Milk Yield [PDF]

Livestock Science
Social 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 ...

The Effect of Thermal Environment on Daily Milk Yield of Dairy Cows [PDF]

Macedonian Veterinary Review, 2016
Abstract The primary objective of this research was to evaluate the impact of environmental air temperatures on the milk production of dairy cows. Therefore, the experiment was carried out at the height of summer (from 15th of June to 15th of September) in three small family dairy farms and one commercial dairy farm.

Technical note: Variation in daily milk yield calculations for dairy cows milked in an automatic milking system [PDF]

Journal of Dairy Science, 2010
An accurate estimation of the daily milk yield of dairy cows milked in an automatic milking system is not obvious because of variations in milking intervals and frequencies. Daily harvested milk varies substantially, and developing a method to be used for estimating daily milk production is of great importance.

Effects of Twice-Daily Nursing on Milk Ejection and Milk Yield During Nursing and Milking in Dairy Cows [PDF]

Journal of Dairy Science, 2008
Milk production and hormonal responses to milking in Holstein cows that were milked twice daily, and that either also nursed calves twice daily 2 h after milking for 9 wk after calving (n = 10) or that served as nonnursing controls (n = 8) were examined to assess how nursing affected responses to machine milking.

Predicting bovine daily milk yield by leveraging genomic breeding values

Computers and Electronics in Agriculture, 2023
The main goal of this work, conducted on a herd of 502 Holstein cows situated in Italy, is to propose a machine learning-based approach to forecast the individual bovine daily milk production by explicitly leveraging genotypic information. As part of our study, we also evaluated the importance in the prediction of genotypic and phenotypic variables ...
