At the high market stage, most pig friends wrote to ask how to build a large-scale pig farm. How to build the scale of 200 sows, is there a reasonable design scheme, and what is the breeding cycle? Based on the above problems, we put forward this plan for 200 sows for your reference and study. Next, let's see how to plan!

I. Target scale

Build a pig farm with an annual output of 4000 lean commercial pigs. According to the average annual supply of 18 commercial pigs per sow, the pig feeding capacity in the whole field is as follows:

1. sow production:

Raise and produce 220 sows a year, including reserve sows 10, and 50 reserve sows a year (raised in two batches, and the sow population will be updated according to the elimination rate of 25%); The actual productive sow is 220× 92% (about 8% sows can't produce) =202.

2. Wild boar:

9 breeding boars are raised and produced every year (the ratio of male to female is 1: 25), and 2 reserve boars are raised (or introduced) every year.

3. Production cycle:

42 weeks from breeding to listing.

16 weeks pregnancy +4 weeks lactation +6 weeks lactation+16 weeks fattening =42 weeks.

4. Reproductive cycle:

16 weeks pregnancy +4 weeks lactation+1 week breeding +2 weeks ineffectiveness =23 weeks.

52 weeks /23 weeks =2.27 fetuses/sow/year.

5. Production standard:

202 ×2.27 fetuses/year =458 fetuses/year, 9 fetuses/week.

9 fetuses/week× 9 weaned piglets/litter× 97% = 79 weaned piglets/week.

79×97%(3% protective mortality) =76 pigs leave the nursery/week.

76×98%(2% fattening mortality) =75 slaughter pigs/week.

6. Group maintenance standards:

The life span of sows ranges from 5.5 to 5.75, with an average of 5.67.

Average service life = 5.67/2.27/ year =2.5 years.

Number of sows updated annually = 202× 40% (annual update rate) =80.

Average life span of boars =2 years.

Annual update number of boars = 9× 50% (annual update rate) =5.

7. Feed utilization rate:

Annual output of 4,000 commercial pigs:

4000 heads × 100kg×3.5: 1 feed weight ratio = 1400 tons of feed/year.

Among them, sow feed:

202 pigs ×365 days× 2.75 kg/day =203 tons/year, about 1 ton/sow/year.

Feed for suckling pigs: 79 suckling pigs/week× 52 weeks/year =4 108 pigs.

4108×17kg (25kg ~ 8kg )× 2.0:1material weight ratio = 140t/ year.

Production of feed for finishing pigs;

4000 heads/year × 75kg (100 ~ 25kg) × 3.5: 1 feed weight ratio =1050t/year.

Total feed consumption = 203+140+1050 =1393 tons, equivalent to 6.6 tons/sow/year.

8. Water consumption estimator:

According to 20 liters of water per pig per day (50% of which is drunk, 50% is washed, and so on). ),

Equivalent to 200 liters of water per sow (10 piglets) per day, then:

202 sows × 200 liters/day =40400 liters/day = 40 tons of water/day.

202 sows adopt a balanced production mode throughout the year from farrowing to fattening, with 9 farrowing per week.

The site and equipment of the following pigs are estimated on this basis.

2. Estimate the site and equipment of each pig herd.

1.sow navigation column: 179, in which:

Location column of pregnant sow: 108 (12 weeks ×9 fetuses/week, counting from 4 weeks of pregnancy confirmation to 1 week * * *.

12 weeks).

Positioning column for eliminated sows: 3 sows (1 sow/week× 3-week detention period)

Location column of breeding sows: 68 sows (2 weeks weaning to re-breeding period +4 weeks pregnancy confirmation, 6 weeks /80% delivery rate ×9 fetuses/week).

2. Spare sow farm: 6 rows (12 weeks × 1.5 sows/week /3 sows/row).

3. sow breeding column: 2 (9 sows/week /80% delivery rate = 1 1 sow/week, breeding for 2-3 times/

Sows, use 2~3 times per column).

4. Boar positioning column: 9 boars (9 boars).

5. Boarding sow number: 45 (4 weeks lactation+1 week turnover =5 weeks, 5×9 litters/week).

6. Nursing pigsty: 24 (6 weeks × 9 fetuses/week× 9 weaned piglets/litter = 486,486/20/pen).

7. Production of fattening pigsty: 72 pigs (16 weeks +2 weeks turnover = 18 weeks, 18 weeks ×79 pigs/week = 1420 pigs, 20 pigs/pen).

8. Isolation fences and management rooms for sick pigs. : a few.

Three. Construction area of pig farm

1. Pig herd area:

179+8+9= 196 pig fields.

196×2.5 m2/block =490 m2

2. Delivery fence area: 45 delivery fences × 8m2 = 360m2.

3. Protective fence area: 486 heads ×0.35 m2/ head = 170m2.

4. Growing and finishing pigsty area:1420×1.0m2/head = 1420 m2.

5. Manage buildings, etc. : 4 rooms × 15m2 = 60m2.

Total construction area of pig farm: 2,500 square meters.

Fourth, civil engineering.

1. Breeding pig house: 2 (including: 1 for breeding and 1 for pregnancy).

13m× 19m/ building× 2 = 494m.

2. Delivery room: 1 building (2 rooms) each with 24m× 8m× 2 rooms = 384m2.

3. Nursery home: 1 building (6 rooms) 14.25m× 4m× 3 rooms = 17 1m2.

4. Production of fattening piggery: 9 buildings, each with 7 1m× 5m× 4 buildings = 1420m2.

5. Manage buildings, etc. : 4 rooms × 15m2 = 60m2.

The total piggery area of the above five items is 2530 square meters.

Five connections, one leveling and infrastructure

1. Road (cement road): the passage between pig farms and pig houses, and the passage connected with the main off-site roads.

2. Water, electricity and telephone: water pipes, transformers, power distribution rooms, power lighting lines, telephones, etc.

3. Fence: In addition to the river, paddocks need to be built.

4. Greening: Greening of pig farms.

5. Other infrastructure: disinfection pool (3 lanes), doorman (including disinfection pool and dressing room) and sewage treatment (ditches, etc.). ).

Six, feces and sewage treatment

Building biogas digesters to solve pollution problems.

Seven. land expropriation

The land required for pig farms is about 2.5~3 times of the building area, and some office facilities are about 10~ 12 mu.

Eight. capital budgeting

(1) civil engineering

1. pigsty: the total area is 2,530 square meters, calculated by 400 yuan/square meter, * * * is10/10,000 yuan.

2. Equipment purchase and installation cost: 500,000 yuan.

3, three links and one leveling and infrastructure costs:

Afforestation and sewage treatment costs (ditches, etc.). ) on roads, water, electricity, fences and pig farms.

(2) Introduction fee for breeding pigs

1. sow: 220 ×2800 yuan/head = 6 1.6 million yuan (subject to the introduction of reserve pigs).

2. Boars: 9× 4,000 yuan/head = 36,000 yuan.

(3) Other supporting investments

The supporting investment of pig farms also includes the purchase of transportation tools, feed plant equipment, heating facilities, biogas digester construction and working capital. There is no budget here. Only the total investment of the above two items is 26.5438+0.52 million yuan.
