Problems solved by technology

[0003] However, due to the low nutritional value of cassava such as protein, amino acid, fat and fat-soluble vitamins, and the lack of hydrogen cyanide-linamarin and lotaustraline, cassava is used in conventional feed for pigs. Usually less than 40%, it is more limited to the feeding of pigs, feed less males and sows, and the proportion of too high mesh number will often affect the growth and development of pigs, especially in piglets and pregnant sows In the feed formula of the period, the demand for nutrients and the quality requirements were increased, and the digestive system was more sensitive to the reaction of the low-grain compound feed. The existing low-grain compound feed containing a high proportion of cassava was difficult to meet the needs of piglets and piglets. The growth needs of pregnant sows lead to slow growth of piglets, prolonged slaughter cycle, decreased body condition of pregnant sows, low feed intake, and large loss of backfat after weaning

Abstract

The invention provides a high-grain-to-low-grain type cassava feed and a preparation method thereof.The method comprises the steps that 1, cassava is peeled, diced, soaked in clear water, dried and smashed, and cassava powder is obtained; (2) soaking cassava leaves and cassava peels in a sodium chloride solution, cleaning, drying in the sun and crushing to obtain a cassava leaf and peel mixture; (3) cleaning, drying and crushing the sugarcane tail leaves and the ramie leaves, adding an acetic acid aqueous solution, acidizing at 10-15MPa, adding a biological agent and a sugar solution, and fermenting to obtain a digestion-promoting fermentation mixture; (4) mixing the cassava powder, the cassava leaf and peel mixture, the pine needle meal and the digestion-promoting fermentation mixture to obtain a cassava feed base material; and (5) adding a protein supplement, a mineral supplement and a nutritional seasoning auxiliary agent, mixing, and granulating to obtain the low-grain cassava feed. The low-grain cassava feed prepared by the invention is more suitable for feeding piglets and pregnant sows, promotes the growth and development of the piglets, shortens the slaughtering time, reduces the weaning backfat loss of the sows, and ensures the reproductive performance of the sows.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a high-grain-to-low-grain type cassava feed and a preparation method thereof. Background technique [0002] With the current price of feed raw materials rising day by day, it is an inevitable trend to seek more or more alternative energy materials to meet the needs of livestock and poultry for dietary energy. Studies have shown that cassava is a root energy feed raw material, which is rich in carbohydrates and can always reach 3560kcal / kg, which is not much different from the 3870kcal / kg of corn. Therefore, in the existing pig compound feed, it is gradually used Cassava replaces energy feed such as corn and wheat. [0003] However, due to the low nutritional value of cassava such as protein, amino acid, fat and fat-soluble vitamins, and the lack of hydrogen cyanide-linamarin and lotaustraline, cassava is used in conventional feed for pigs. Usually less than 40%, it is m...
