Piglet cutting: forage + pellet feed

Pigs are omnivores and have strong ability to eat and use pasture. In particular, the ability of local fine pig breeds to use forage is quite prominent. The nutrients in the pasture can be fully digested and absorbed by the pigs, and the nutritional value is higher. Tests and production practices have shown that pigs can eat green and green feed all the year round, and they can receive the effect of “reducing the essence with green, reducing the cost and increasing efficiency”. Feeding sows with high-quality pastures can meet nutritional needs and increase litter size. Feeding fattening pigs can improve meat quality.

From the composition of the food chain of “pig-grass”, it is feasible to grow grass and raise pigs. According to the nutritional needs of the pigs and the ability to use the forage, the fattening pigs can be fed with fresh grasses 5 kg to 8 kg per day without affecting the normal growth of the pigs, and the sows can be fed 10 kg to 12 kg. The average yield of pasture fresh grass is about 10,000 kg to 15,000 kg. The fresh grass harvested by planting 1 mu of grass can meet the feeding amount of 20 fattening pigs or 10 sows.

From the perspective of income, it is feasible to grow grass and raise pigs. Under the current production and technical conditions, the feed reward for raising pigs is generally 3:1. Feeding a 100 kg fattening pig requires about 300 kg of concentrate. According to the current feed price, the cost is about 780 yuan. After feeding the grass to replace some of the concentrate, it can save 20 kg to 30 kg of concentrate and reduce the feed cost by 50 to 80 yuan. If weeds are used to feed sows, the use ratio is higher, and more concentrate can be saved, which reduces the production cost.

In areas where the supply of concentrate feed is tight or the concentrate is insufficient, growing grass and raising pigs is a better method. In addition to using cultivated land to grow pigs, farmers can also make full use of idle land such as fields and abandoned land to plant high-quality pasture to develop pig breeding.

The use of grass in the cultivation of pigs, jqe China feed industry information network - based on feed, service animal husbandry

Planting pigs must choose suitable forage species, and combine the seasons to determine the way the grass is raised. In summer and autumn, the grass-raising pigs are fed directly with fresh grass as the main method of forage utilization; in winter and spring, the grass with high-quality grass powder or beating silage is used as a mixed feed ingredient.

1. Forage fresh feeding method: Forage planting time is selected in spring and summer, planting saplings such as glutinous rice, polymer grass, chicory, etc. Fresh grass is added in 15% to 30% of the diet, and 1 mu is supported for every 10 pigs. grass.

2. Forage grass grass powder is added to the concentrate to feed. The planting varieties are alfalfa, Mexican corn, high-dan grass, etc. Fresh grass can be used in summer and autumn, and added to the diet in winter and spring. The amount of forage powder accounts for 8% to 15% of the diet, and 0.5 mu is planted for every 10 pigs. Jqe China Feed Industry Information Network - based on feed, serving animal husbandry

3. Forage grass beating or cutting to make silage and concentrate feed feeding method: As long as the pasture is directly used in the season, there is still surplus, you can beat or cut the silage, and feed with the concentrate in the season of lack of green feed. The specific amount of dietary supplement can be determined according to the breed, growth stage and physiological condition of the pig.

European chicory, pine leaf herb, bitter amaranth, American grain glutinous rice, Rumex, alfalfa, Mexican corn, high dan grass, red bean grass and other pastures, the nutrient composition is more comprehensive, according to dry matter calculation, crude protein content High, generally above 12%, the highest is up to 30%, and the amino acid type is complete, the utilization rate is high, which can make up for the shortcomings of protein and amino acid types in grain feed, and also contains rich vitamins and inorganic salts. Low, easy to digest, good palatability, high land yield per unit area, low production cost and wide range of sources.
