Problems solved by technology

However, piglets are in a critical period of development when they are weaned, and their own functions are not perfect. In addition, environmental changes and the influence of pathogenic microorganisms and many other factors will cause stress reactions in piglets, resulting in a decrease in feed intake and growth rate, causing diarrhea and even death. , causing huge losses to the economy

Embodiment 1

[0060] A antibiotic-free complete compound feed for weaned piglets that can be used for feeding in winter is made of the following raw materials in parts by weight:

[0061]

[0062] A preparation method for antibiotic-free full-price compound feed for weaned piglets that can be fed in winter, the steps of which are:

[0063] A. According to the above ratio, finely pulverize corn, peeled soybean meal, puffed soybean, fermented soybean meal, and insect protein powder (40), and the pulverizer is equipped with a Ф2.5 sieve plate to control the crushing particle size;

[0064] B. The pulverized raw materials and other raw materials in the formula are first accurately weighed by the batching scale, and then put into the mixer for mixing. The mixing time is 140 seconds, and the coefficient of variation CV<5%;

[0065] C. Put the evenly mixed compound feed into the conditioner, and fully gelatinize under the condition of high temperature (80°C) steam screw extrusion;

[0066] D. ...

Embodiment 2 to Embodiment 5

[0074] A kind of antibiotic-free full-price compound feed for weaned piglets that can be used for winter feeding, it is made of the following raw materials by weight:

[0075]

[0076]

[0077] Its preparation steps are identical with embodiment 1. In Example 2-5, without adding whey powder and soybean protein concentrate raw materials, a better technical effect is also obtained.

[0078]The yeast nucleotide is a kind of yeast nucleotide with high nucleotide Candida tropicalis as raw material, which is obtained through liquid submerged fermentation, cell wall breaking, enzymatic hydrolysis, separation and purification, and low-temperature drying. It has immune activity and anti-tumor Functional nucleotide polysaccharides. Said lysozyme is a kind of hydrolase specially acting on the cell wall of microorganisms. The glucan is a water-soluble β-glucan product of a new structure produced through the fermentation of a patented strain of a new type of marine microorganism. ...

Embodiment 6

[0080] The application of a full-price compound feed in feeding weaned piglets in winter is as follows: feeding at 8:00 am, 12:00 noon, 4:00 pm and 8:00 pm respectively, and the ratio of feeding 4 times a day is 3 :1:3:1. The total amount of feed fed every day is at least 5% of the previous day's body weight, and the suggested feeding amount of the present invention can ensure that the piglets can eat completely. The difference between the highest and lowest temperature in the house should not be higher than 8°C due to the change of outdoor temperature in winter. Feed for at least 21 days.

[0081] This example is an example of relevant experimental data using the full-price compound feed prepared in Example 1, which is an example of the use effect.

[0082] Selected animals: 192 piglets of Duroc Landrace × Large White three-way hybrid barrows were selected for the test, with a weight of 6.5 kg;

Abstract

The invention discloses a full-price antibiotic-free compound feed for weaned piglets and a preparation method and application thereof. The compound feed is composed of corn, peeled soybean meal, expanded soybeans, fish meal, whey powder, fermented soybean meal, glucose, insect protein powder, soybean protein concentrate, soybean oil, calcium dihydrogen phosphate, mountain flour, citric acid, lysine, acid, yeast nucleotide, glucan, a mineral element premix and an amino acid premix in a certain proportion. No antibiotics are added, zero antibiotic consumption is achieved in the live pig breeding process, the safety of live pig foods is ensured, and green pork products are obtained. The effect is obvious, the feed is simple and safe, through scientific nutritional allocation, the immune functions of the piglets are promoted, compared with other full-price antibiotic-free compound feeds, the survival rate of the weaned piglets is increased by 5-10%, the diarrhea rate is controlled below 5%, and the cost of each pork pig is reduced by 20 yuan in farms as no antibiotics are added.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a full-price compound feed for weaned piglets, more particularly to a method for preparing a full-price compound feed for weaned piglets that can be used for feeding in winter, and also relates to a full-price compound feed for weaned piglets without antibiotics. The use of price compound feed. Background technique [0002] China is the country with the largest pig raising scale in the world. The number of live pigs on hand, the number of slaughtered pigs and the output of pork are close to half of the world. But China is also the world's largest producer and consumer of antibiotics. In a survey in 2007, the estimated annual antibiotic production in China was 210 million kg, of which 46.1% was produced by animal husbandry (Zhu YG, Johnson TA, Su JQ et al., Diverse and abundant antibiotic resistance genes in Chinese swine farms[J], PNAS, 2012,110(9):3435–3440). As emerging pollutants, ...
