Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to aim at the transformation of piglets from mainly eating breast milk to eating solid feed during weaning and other weaning stress processes, which cause piglets to have poor palatability to feed and affect the intestinal tract of piglets To address the problems of developmental form and growth rate, a method for preparing an appropriate amount of feed for piglets is provided. The present invention firstly extracts water-soluble protein from soybean meal, and performs Maillard reaction on the water-soluble protein and lactose to obtain the Maillard product, namely It is a flavoring agent for piglet feed, and then use waste food from the kitchen to add lactic acid bacteria and yeast powder to ferment to obtain a fermented product. After mixing the fermented product with corn flour and wheat bran powder, add piglet feed flavoring agent to release milk fragrance and stimulate pigs' sense of smell and Taste aroma, improve feed intake of piglets

example 1

[0018] First, weigh 200g of soybean meal, put it in an oven, dry at 60°C for 5 hours, crush it after drying, pass through a 100-mesh sieve to obtain soybean meal powder, add the soybean meal powder into deionized water at a mass ratio of 1:10, stir and mix for 10 minutes before using Adjust the pH to 11 with 25% sodium hydroxide solution by mass fraction. After adjustment, microwave extraction at 250W for 8 minutes. After the extraction, centrifuge to obtain a supernatant, and adjust the pH to 4 with 15% hydrochloric acid by mass fraction. After standing for 3 hours, centrifuge. The precipitate was obtained; then the above precipitate was added to deionized water at a mass ratio of 1:6, and after stirring and dissolving, lactose with 1.5 times the mass of the precipitate was added, and after stirring and mixing evenly, the pH value was adjusted to 10 with a mass fraction of 12% sodium hydroxide solution. , heated to 110°C after adjustment, kept stirring for 1 hour, then cooled ...

example 2

[0021] First, weigh 250g of soybean meal, put it in an oven, dry it at 65°C for 6 hours, crush it after drying, pass through a 110-mesh sieve to obtain soybean meal powder, add the soybean meal powder into deionized water at a mass ratio of 1:10, stir and mix for 15 minutes before using Adjust the pH to 11.5 with 25% sodium hydroxide solution. After adjustment, extract with microwave at 265W for 9 minutes. After the extraction, centrifuge to obtain the supernatant. Use 15% hydrochloric acid to adjust the pH to 4.5. After standing for 4 hours, centrifuge Obtain a precipitate; then add the above precipitate into deionized water at a mass ratio of 1:6, stir and dissolve, add lactose with 1.75 times the mass of the precipitate, stir and mix evenly, and adjust the pH value to 10.5 with a mass fraction of 12% sodium hydroxide solution , adjusted and heated to 112.5°C, kept stirring for 1.5h, then cooled to room temperature to obtain the mixture, and set aside; then weighed 4kg of kit...

Abstract

The invention discloses a preparation method of a feed for increasing feed intake of piglets and belongs to the technical field of feed preparation. The preparation method comprises the steps that firstly, a water-soluble protein is extracted from soya bean meal, the water-soluble protein performs Maillard reaction with milk sugar to obtain a Maillard product, namely a piglet feed flavoring agent, then kitchen waste foods are utilized, lactic acid bacteria and saccharomycetes powder are added, fermentation is performed to obtain a fermentation product, the fermentation product, corn flour and wheat bran powder are mixed, then the feed flavoring agent is added and releases a milk flavor to stimulate the smell and gustation of the piglets, and the feed intake of the piglets is increased. The prepared feed can make weaned piglets eat the feed as early as possible, the feed intake of the piglets is increased, development of the digestive tracts the piglets is promoted, and the feed makes the piglets weaned in advance so as to promote growth and development and decrease digestive tract diseases.

Description

technical field [0001] The invention discloses a method for preparing feed for improving feed intake of piglets, and belongs to the technical field of feed preparation. Background technique [0002] Pig breeding is an important part of livestock and poultry breeding in my country, and the quality of piglets and the speed of growth are directly related to the time and amount of meat produced by pigs. In recent years, with the improvement of animal breeds and the advancement of breeding technology, most pig farms have adopted the breeding method of early weaning. The feeding of weaned piglets has become an important link in pig production. Although early weaning has the advantages of promoting early feeding, increasing weaning litter weight, and reducing feed-to-meat ratio, due to the incomplete development of the digestive system and low immune function of suckling pigs in the early stage, it is easy to Diarrhea or anorexia occurs, so the requirements for weaned piglet feed ...
