In order to guide farmers to take full advantage of the advantages of land and garden resources and accumulate development funds, according to the analysis of the status quo of farmers' pig production, five kinds of â€œplanting + small-scale pig raisingâ€ technology models are proposed for reference. First, the combination of the five types of farming and breeding of pigs in the courtyard. 1. Feeding in small batches, with 40 heads per year. Planting structure: 6003 square meters (9 acres) of corn, 1334 square meters (2 acres), 2001 square meters (3 acres) of soybean green (replicon). Pig production: At the beginning of January, February, March and April, five piglets with more than 7 kg were purchased. From the end of the 4th month, 5 heads were slaughtered per month and 5 heads were added after slaughter. Feeding methods: Feeding by stages, 120 days for slaughter. Production efficiency: The annual slaughter of 8 batches of 40 heads, the average live weight of 85 to 90 kg, 5 per head of income 2500 ~ 3200 yuan, profit 250 ~ 500 yuan, annual income of 20400 ~ 25200 yuan, profit of 2000 ~ 4,000 yuan. 2. Equally raised every other month, with an annual slaughter of 60 heads. Planting structure: 8671 square meters (13 acres) of corn, 2001 square meters of loquat, 3335 square meters (5 acres) of soybean green (double cropping). Pig production: In the first, second, fourth, sixth, seventh and ninth months of each month, pigs weighing more than 7 kg were purchased, each batch of 10 pigs were reared in groups. Feeding methods: Feeding piglets and finishing pigs at the stage and slaughtering for 110 to 120 days. Production efficiency: 6 pigs in a total of 60 pigs in a row, with an average live weight of about 90 kilograms, and each outgoing: column of income of 5,300 to 6,500 yuan, a profit of 500 to 1,000 yuan; annual income of 3,180 to 39,000, a profit of 3,000 to 6,000 yuan yuan. 3. Seasonal feeding, with an annual output of 80 heads. Planting structure: species of 12006 square meters (18 acres) of corn, 2668 square meters (4 acres), 4002 square meters (6 acres) of soybean green (double cropping). Pig production: purchased in the beginning of January, March, June and September respectively. More than 7 kilograms of piglets, each batch of 20 or more, were reared in groups. Feeding methods: feeding in small, medium, and large stages, and slaughter in about 110 days. Production efficiency: 4 batches of 80 pigs each year with an average weight of 90 kilograms; a quarterly slaughter, income of 10600 to 13,000 yuan, profit of 1,000 to 2,000 yuan; annual slaughter of 4 batches, income of 42400 to 52,000 yuan, profit of 4000 ~ 8,000 yuan. 4. Self-breeding breeding, 100 slaughter in year. Planting structure: 16675 square meters (25 acres) of corn, 4669 square meters (7 acres), 5336 square meters (8 acres) of soybean green (double cropping). Pig production: Five young sows were purchased from January, and the breeding period was at the beginning of June. About 50 pigs were born at the beginning of October. The breeding pigs and sows were newly bred in November. After that, 50 pigs were kept every 5 months. The scale. Feeding methods: divided into pregnant sows, lactating sows, piglets, finishing pigs, feeding from the piglets landing to slaughter 150 days to 160 days. Production efficiency: according to species sows using 5 years of calving 11 nests calculation, breeding slaughter 540 The head hog pigs have an annual average slaughter of 110; a batch of slaughter every 5 months, income of 26,500 to 29,000 yuan, profit of 2,500 to 5,000 yuan; 2.5 batches of annual slaughter, income of 66,000 to 72,000 yuan, and profit of 5,500 to 11,000. 5. Multi-family joint breeding, with 120 slaughters per household per year. Production organization: 30 piglets breeders in one village or one township, and 12 sows in one household. The annual output of piglets is 6,000, which is used to feed 50 households. Each household has 120 slaughterhouses per year. It has also established a breed of boar raising households, a small plant that processes 1,500 tons of feed, and two hog sales. Planting structure: piglet breeding households, one family of 6670 square meters (10 acres) of corn, 2001 square meters of alfalfa, 3335 square meters of soybean green (replanting); finishing pigs, one household 18009 square meters (27 acres) of corn, 4002 square Rice bran, 6003 m2 bean green (double cropping); boar breeder, 1334 m2 corn, 667 m2 (1 acre) alfalfa, 2001 m2 soybean blue (replanted). Feeding methods: standardization, standardization, feeding in stages, piglets being slaughtered for 30 days, hogs being slaughtered 110 to 120 days. Production efficiency: Piglet breeding households, 200 to 240 pigs per year, income of 20,000 to 24,000 yuan, profit of 8,000 to 12,000 yuan; pigs for finishing pigs, annual slaughter of 120 pigs, income of 63,600 to 69,600 yuan, profit, 6000 to 8000 Yuan; boar raising households, 9007 first-time improvement, income of 24,000 to 32,000 yuan, profit of 12,000 to 16,000 yuan; feed processing households, processing income of 70,000 to 100,000 yuan, profit of 10,000 to 15,000 yuan; sales of pig farmers, per household Profits of more than 10,000 yuan. Second, the use of the above technical model conditions 1. The use of the above 1,2,3 kinds of technical models should have four conditions: 1 according to standard building warmhouse. Among them: Mode 1 is built in a circle of 24 square meters and is divided into 4 small rooms with a fence. Mode 2 is built in a circle of 30 square meters and divided into 6 square meters, 1 room and 12 square meters. Mode 3 is built into a circle of 50 square meters and divided into 10 square meters 1 room, 15 square meters 1 room, 25 square meters 1 room. 2 Preparation of working capital from 2000 to 4,000 yuan. 3 prepare self-produced feed 9800 ~ 19600 kg (including 5 homes of agricultural and sideline products), outsourcing quality additives 294 ~ 588 kg. Among the stocks, 63% were corn, 13% were high-quality alfalfa, 9% were soy flour, 12% were by-products such as bran, and 3% were high-quality additives. 4 The implementation of standardized feeding procedures, the breeders are specially trained. 2. There are five conditions for adopting the 4th technical model: 1 Construct a 60m2 greenhouse and divide it into 6 small rooms. 2 Raise long or large long-term hybrid sows and use Su Dabai boars for scientific breeding. 3 prepare working capital, breeding period 1,500 yuan, fattening period of 4000 to 6,000 yuan. 4 Prepare self-produced feed 28,000 kg (including 5 households of agricultural and sideline products), and purchase 840 kg of high quality additives. Among the stocks, 63% were corn, 13% were high-quality alfalfa, 9% were soy flour, 12% were by-products such as bran, and 3% were high-quality additives. 5 Implement standardization and standardization of feeding procedures, and keep personnel specially trained. 3. The adoption of the fifth technology model should have seven conditions: 1 There are one or several farmers who are enthusiastic about the development of this industry to take the lead in joint ventures, establish pig raising associations, and develop members. 2 Hire 1 to 2 professional and technical personnel for guidance. 3 In order to rebuild the backyard house as a warm shed, the household needs to change the construction fee from 1000 to 1300 yuan (excluding timber and construction costs). Four kinds of sow households raised binary hybrid pigs, while male boar households raised Su Dabai purebred pigs. 5 Each household needs to produce working capital 6000 to 12,000 yuan. 6 Feed reserve: self-produced feedstuffs: 11000kg for piglet breeding, 29200kg for finishing pigs, 2,300kg for boar raising; high quality additives for outsourcing: about 350kg for piglet breeding, 900kg for finishing pigs, and boar raising for 70 kg. Among the stocks, 63% were corn, 13% were high-quality alfalfa, 9% were soy flour, 12% were by-products such as bran, and 3% were high-quality additives.
