Late lactation cow management
After the mid-lactating period of dairy cows, and before the dry period, it is the end of lactation. Generally, it refers to 201 days postpartum to stop milking. After 200 days of milking, dairy cows have a significant decrease in body weight. They should appropriately increase the amount of feed during the late lactation period to restore the body condition of dairy cows, but care must be taken to prevent over-fertilization. According to relevant energy studies abroad, it is shown that in the late lactation period, the cows strengthen their feeding and provide supplementary feeding. This is more than waiting until the dry period, and it is more cost-effective to use the feed. Therefore, at present, more emphasis on foreign countries to strengthen the rearing of the lactation, so that the body of cattle has a slight accumulation of nutrients, and when entering the dry period, the cattle's body condition has been basically restored. At the end of lactation, the dry matter of dairy cows should account for 3% to 3.2% of their body weight. The unit of energy per kilogram of dairy cows is 1.87, crude protein is 12%, calcium is 0.45%, phosphorus is 0.35%, and the ratio of concentrates and coarse materials is 30. : 70, crude fiber content shall not be less than 20%. In this period, the diet is mainly made of green roughage, and it can be used with appropriate concentrates. CPE is the sub-data of saturation high grade (FEN), the appearance is white powder, non-toxic and odorless, with excellent weather resistance, ozone resistance, chemical resistance and aging resistance function, with excellent oil resistance, flame retardant and coloring function. Excellent toughness (still flexible at -30℃), excellent compatibility with other polymer materials, high differentiation temperature, differentiation to produce HCl, HCl can catalysis CPE dechlorination reaction.
