Abstract:
Complementary feed or feed supplement is a feed ingredient that is added to animal feed to complement the nutritional content of feed in meeting the needs of livestock. Feed supplements are additional feed ingredients intended to add nutrients to animal feed, where the added nutrients are digested or help the digestive process. This study aims to evaluate the use of mineral-plus as a feed mixture for dairy cows on the appearance of milk production and quality.
The used material with carried out on 30 lactating cows 1-3. 250 ml milk samples from the morning and evening milking of each cow were analyzed for milk quality analyzed with a Milk scan tool. The mineral added to the concentrate feed is 2% with the mineral composition in the form of a mixture of several macro, micro and herbal. The variables observed included feed consumption, milk production and quality (specific gravity, fat content, protein content, total solid content and pH value) of PFH dairy cows and the data were analyzed using descriptive statistical methods. The results showed that the average consumption of forage feed was 48.83 kg/head/day and concentrate was 13.42 kg/head/day. The average high milk production is 35.46 liters/head/day. The average quality of milk which includes fat content is 6.39%, SNF content is 8.13%, total solid is 14.48%, specific gravity is 1.0233, protein content is 4.57%, lactose content is 3.97 % and the pH value of milk is 6.48.This study shows that cow's milk production and quality is at a very high level above the average production of Friesian Holstein crossbreed cows. |
