Problems solved by technology

However, there is no further disclosure of the division of specific physiological stages of sows during pregnancy and feeding methods. Feeding two rations every day is inconvenient and confusing, and it is still not very suitable for feeding pregnant sows

Embodiment 1

[0053] The preparation of embodiment 1 alfalfa meal

[0054] The preparation method of the alfalfa meal is as follows: crush the harvested disease-free fresh alfalfa at the early flowering stage to a particle size of 3mm, add 15% of the mass of corn flour, mix evenly, add 0.8% of the mass of the mixture of degrading enzymes, enzymolyze at 50°C for 50min, Stir, cool down to 36°C naturally, inoculate ensilage agent with 0.2% enzymolysis solution mass, ferment at constant temperature for 60 hours, concentrate the fermented liquid under reduced pressure, crush at 25°C to a particle size of 0.4mm, and obtain alfalfa powder;

[0055] The silage agent was purchased from Hebei Yiwei Microbial Technology Co., Ltd., model: EVQCJ; brand: Yiwei brand; active substance content: lactic acid bacteria ≥ 3 billion / ml;

[0056] The degrading enzyme is formed by uniformly mixing amylase and cellulase, and the mixing mass ratio is 3:2;

[0057] The live lactic acid bacteria content of the alfalf...

Embodiment 2

[0058] The preparation of embodiment 2 Chinese herbal medicine extract

[0059] The Chinese herbal medicine extract is prepared from the following raw materials in parts by weight: 60 parts of angelica, 60 parts of chuanxiong, 55 parts of amomum, 50 parts of divine music, 50 parts of malt, 50 parts of motherwort, 42 parts of codonopsis, 42 parts of astragalus, and 42 parts of honeysuckle , 40 parts of Scutellaria baicalensis, 40 parts of Lingcao, 35 parts of Forsythia, 35 parts of Atractylodes macrocephala, 35 parts of mint, 30 parts of licorice, 30 parts of nepeta, 30 parts of tangerine peel;

[0060] The preparation method of the Chinese herbal medicine extract is as follows: respectively pulverize the above-mentioned Chinese herbal medicines to a particle size of less than 2 mm, then uniformly mix in a container and add 5 times the weight of water, control the temperature at 80° C. for 2-4 hours, and then lower the temperature to 55° C. ℃, add a mixed enzyme preparation of ...

Embodiment 3

[0063] Example 3 Preparation of Yeast Culture

[0064] The preparation method of the yeast culture is as follows: pulverize the beer malt, add warm water 5 times its mass, adjust the pH value to 5.2 with lactic acid, add a compound enzyme with 0.3% of the malt mass to carry out segmental enzymatic hydrolysis, and decompose the protein at 50°C for 90 minutes , then saccharify at 62°C for 60 minutes, wait until the saccharification is complete, cool down to 12°C, take 1 / 3 of the mass of the mash, inoculate it with 2% of the mass of brewer's yeast, pass through sterile air for 10 minutes, ferment for 24 hours, and then add the remaining 2 / The saccharified mash of 3 was fermented for 30 hours to obtain a fermented liquid, which was concentrated under reduced pressure and pulverized at 20°C to a particle size of 0.4 mm to obtain a yeast culture;

[0065] The mass percentage of the compound enzyme consists of: 30% fungal α-amylase, 20% pullulanase, 20% neutral protease, 10% bromela...

Abstract

The invention discloses a pig feed and application thereof, belonging to the technical field of sow feeding. Physiological stages of a pregnant sow are further subdivided and detailed according to physiological characteristics and nutritional requirements of the sow during a pregnancy period, the feed suitable for each stage is provided according to the nutritional requirements of the pregnant sow at each stage each day, and a reasonable and detailed feeding method is designed by combination with body conditions, feeding environments and the like of different pregnant sows, so that the exercise of the pregnant sow can be effectively increased, nutritional substances can be accurately and timely fed, the functions of a digestive absorption system and an immunity system of the pregnant sow can be promoted and improved, the number of living piglets is remarkably increased, the embryo mortality is reduced, the birth weight of the piglets is increased, and the uniformity of the piglets is improved.

Description

technical field [0001] The invention relates to pig feeding, in particular to a pig feed and its application. Background technique [0002] The feeding and management level of breeding pigs reflects the level of pig raising in a country. For a farm, the key to its profitability also benefits from the feeding and management of sows. For quite a long period of time, sow breeding in my country has been an extensive attitude. Most rural retail households use green feed rich in crude fiber as the main source of nutrition to raise sows. However, with the improvement of varieties and the expansion of breeding scale, the breeding level has been continuously improved, and farmers have begun to use relatively nutritious commercial feed, which has improved the reproductive performance of sows to a certain extent. But generally speaking, compared with the research on the nutrition and physiology of suckling piglets, the nutrition and physiology of sows and feed preparation technology ...
