Novel composite premix for milking cow in nonlactating period and production method thereof

Abstract

The invention discloses a novel composite premix for a milking cow in a nonlactating period and a production method thereof, and belongs to the technical field of feed mixing technology and production. Aiming at the characteristics of nutrition physiological characteristics of the cow in the nonlactating period, the premix is prepared by using vitamin A, vitamin D3, vitamin E, niacin, biotin, copper oxychloride, ferric sulfate, zinc sulfate, manganese sulfate, potassium iodide, sodium selenite, cobalt chloride, urease inhibitor, dihydropyridine, 2,6-di-tert-butyl-methyl phenol, palm fatty acid, calcium hydrophosphate, mountain flour, powdered rice hulls and zeolite powder as raw materials through the processes of raw material weighing, vitamin premix additive preparation, trace element premix additive preparation, co-mixing, inspection, package and finishing product. The premix has reasonable formula, balanced nutrition and scientific production and processing technique. Tests prove that the premix effectively improves the body condition of dry cows, reduces generation rate of metabolic diseases, improves productivity of postpartum cows, and has clear feed effect and obvious economic benefit.

Description

technical field The invention relates to a compound premixed feed, which belongs to the field of feed compounding technology and production technology. Background technique The dry period refers to the period when the cows stop lactating before giving birth. The reasonable nutritional level at this stage is directly related to the lactation performance of the postpartum cows, and even more related to the health and high yield of the cows in the future. The dry milk period is the storage period of nutrients, the regeneration period of mammary gland tissue, the rapid growth and development period of the fetus, and an important stage for the recovery of the whole body function. Therefore, the nutritional level during the dry period is extremely important for dairy cows. However, because this physiological stage has no economic benefits, some dairy farmers have not paid enough attention to this physiological process, resulting in many unnecessary losses. The invention uses mul...
