Composite feed additive for preventing and curing dairy cow allotriophagy

Abstract

The invention discloses Yishiling, a composite feed additive for preventing and curing dairy cow allotriophagy and a preparation method thereof. The preparation is prepared by procedures of pre-processing and agitating the raw materials of bone meal, chalcanthite, magnesium sulphata heptahydrate, cobalt chloride, sodium selenite and some auxiliary preparations; the invention is characterized in that in the aspect of raw material composition, trace elements which are safe, absorbable and lacked by dairy cow suffering allotriophagy are taken as the main raw materials and other trace elements, absorbefacient and the like needed by dairy cow are added to adjust nutrient balance, condition organism nutritional and metabolic balance, and restore the organism to normal healthy level; and in the aspect of processing technique, firstly the extremely trace elements are refined to be even and stable in contents, secondly the processing and adding sequence of the raw materials is implemented at intervals according to the mutual antagonism relations between the trace elements, and the contact between the trace elements is reduced as much as possible, thus ensuring the safety of product quality and dairy cow.

Description

technical field [0001] The invention relates to a compound feed additive for preventing and treating heterophilia of dairy cows, and also relates to a preparation method of the feed additive. Background technique [0002] Cow pica is a nutritional metabolic disease, which is a syndrome of mineral metabolism disorder in cattle caused by the lack of certain minerals. The clinical manifestations of the disease are heterophilia, loss of appetite, weight loss, decreased productivity, and severe cases lead to death. It has been confirmed through investigation that in some areas of Heilongjiang Province, its morbidity rate is 37%, and the mortality rate is 16%, which is very harmful to the cattle breeding industry. The degree of intensification of dairy cows in my country is not high, and the extensive feeding method is mainly free-range. With the increase in the number of dairy cows and the reduction of forage and feed resources, the feeding and management of dairy cows cannot ke...

Problems solved by technology

At present, there is no complete report on this in China. It is only theoretical guidance or blindly adding common additives in the feed, or compulsively supplementing the feed, which is very unscientific, and the clinical effect is not good. The mutual interference between the two mineral elements has the opposite effect

Heilongjiang Province is a key area for the development of animal husbandry in the country, especially the rapid development of the dairy industry, which has a large number and has occupied a dominant position in the rural economy. Mainly grazing, lack of comprehensive nutrition. At the same time, due to the geological characteristics of the area and the high number of dairy cows, the pastures carry too much livestock, the pasture is malnourished, the incidence of cattle pica disease is high, and the economic loss is relatively large.
