Female calves or heifers

Female calves, or heifers, are the most important group of herds that conceive for the first time. The goal is to be able to mate at 13 to 14 months of age and give birth at less than 25 months of age.

Improper breeding causes heifers to spawn sooner or later, and this can lead to irreparable economic damage to a dairy farm.

In order to perform regular breeding of heifers, it is necessary to pay more attention to the application of management factors, especially nutritional factors, and its nutritional needs must be met according to the type of animal production at each stage.

Heifer feed ration

Dry matter: A heifer during the day should feed 4% of body weight of dry matter. For example, a 250 kg heifer should be fed with 10 kg of feed; Part of this feed is determined by forage and part by concentrate

 The most important criteria for determining the diet required by heifers is to check the status of their body score.

Due to the incomplete growth of heifers compared to adult cows, they need more energy, protein, minerals and vitamins;

Their need for micronutrients is determined by age, weight and climatic conditions, which should be properly supervised by nutritionists and dietitians.
