Nové trendy ve fázové výživě dojnic
REJZKOVÁ, Martina
When feeding dairy cows, quality forage must be the main ingredient. Prolonged feeding of poor-quality feed can lead to metabolic disorders, weak calves, reduced reproductive capacity, mastitis and other problems. Phase feeding is widely used in dairy cattle nutrition because it is probably the best way to meet the nutrient needs of dairy cows at different stages of lactation, even when standing dry. The basis for respecting the physiological needs of dairy cows is the creation of balanced groups of dairy cows. Nutrition is very important, especially in the transition period of dairy cows. That is to say, the 3 weeks before and 3 weeks after parturition, when dairy cows need the best quality feed and, above all, the greatest nutritional care. These six weeks are crucial for maintaining good health, the production and reproductive efficiency of the dairy cow and the profitability of the entire herd. Modern knowledge guarantees higher milk production and better satisfaction of nutrient requirements. In 2021, after almost 20 years, a new standard, NASEM 2021, was published which gives the expected nutrient recommendation for dairy cattle. Other modern findings include the increasing use of robotic milking parlours with automatic feeding, or the use of vitalimeters or pH probes to monitor digestive pro-cesses and overall animal activity.
