AI Technical Summary

Problems solved by technology

However, in actual use, the cows fed anionic salts have seriously reduced their feed intake. The reason is that the palatability of anionic salt products is extremely poor. difficult to increase feed intake

[0031] Instructions

[0032] Since prepartum 30 days or 25 days, every day every head adds 100 grams of the present invention in the mixed concentrate feed. If the amount of mixed concentrate feed per head per day is 5kg, add 2%; if the feed amount is 4kg, add 2.5%.

[0033] The present invention is added in cow feed without affecting the feed intake of cows, thereby providing a basis for increasing postpartum feed intake and milk production of cows, and at the same time preventing retained placenta, milk fever, ketosis, and metritis and postpartum diseases such as ectopic abomasum, and can improve the postpartum reproductive performance of cows.

Abstract

A pre-mixed forage for the cow in later phase of pregnancy to prevent puerperal diseases and improve reproduction ability is proportionally prepared from VE, VD3, VA, ferrous sulfate, copper sulfate, zinc sulfate, magnesium sulfate, magnesium oxide, manganese sulfate, Co mixture, I mixture, Se mixture, ionic carrier, and the master carrier.

Description

technical field [0001] The invention relates to a premixed feed for dairy cows, in particular to a premixed feed for cows in the late stage of dry milk. Background technique [0002] The peripartum period of dairy cows, that is, 3 weeks before farrowing (late dry milk period) to 2 weeks after farrowing (primiparous period) is very important to the health, production and economic benefits of dairy cows. Various infectious and metabolic diseases, such as milk fever, ketosis, retained placenta, metritis, mastitis, and ectopic abomasum, mainly occurred during this period. Although this stage is short, it is critical to the health of the cow and the improvement of milk production throughout lactation. [0003] About 7.2% of highly productive adult cows in the United States suffer from milk fever, and about 66% of multiparous cows suffer from subacute hypocalcemia after calving (Beede et al, 1992). According to information, cows with hypocalcemia are prone to diseases such as re...
