Although sometimes the timing of feeding cows is based on personal convenience, researchers are trying to find out if feeding at certain times will bring some benefits to dairy cows. The resulting effects on milk production, feed intake, and blood chemistry were recorded. The results were published in the November issue of the Journal of Dairy Science.
In this study, the array of cows was fed only once a day in the morning at 9 o'clock or at 9 o'clock in the evening. Blood samples were taken every 2 hours and milk production was recorded in 6 consecutive milkings. The results showed that feeding at 9 o'clock in the evening increased feed intake within 3 hours after spraying, and there was no increase in feed intake, milk production, and milk protein throughout the day. However, evening feeding does increase the milk fat percentage of the producing cows, although the reason is unknown. The study concluded that evening feeding is beneficial to dairy cows without heat stress, but is affected by the number of births.
