As the pig industry has entered the stage of large-scale and factory feeding, many large-scale pig farms have emerged, bringing new vitality and vigor to the pig industry. In this paper, taking the annual slaughter rate of 10000 head pig farm as an example, the initial capital investment is calculated.
The size of the pig farm is mainly determined according to the actual situation or fund conditions.
This paper takes 20000 pigs with annual slaughter rate as an example.
1.1 production scale and layout
The land area of industrialized pig farms and feed plants should be 50 mu.
From the perspective of disease prevention and environmental protection,
it is not suitable to build large pigs in the surrounding areas of large cities
Farms, we can promote ecological breeding in the outer suburbs, such as building pig farms in lakeside,
economic forest areas, vegetable bases and other places.
The scale of pig farms should be simple biological fermentation of manure and urine，
It can be used by fish ponds, orchards and vegetable bases, so as to reduce the cost of sewage treatment.
1.2 determination of breeding pig quantity
The number of breeding pigs shall be determined according to artificial insemination, the ratio of male and female pigs shall be 1:400,
and the conception rate, litter size, lactation rate and the mortality rate of piglets during lactation of sows shall be integrated.
At the same time, 1100 basic sows (including backup sows) and 1100 male pigs about 5 heads.
The number of annual sales is 20000.
2.1 production area
The production area is the main part of pig breeding, including pig houses and production facilities of various pig groups, with a building area of 26390㎡.
Among them, the boar house is 30㎡, the artificial insemination house is 30㎡,
the empty sow and pregnant sow house is 5900㎡, the litter, lactation and care house is 9010㎡,
the growth and fattening house is 11000㎡, the backup house is 210m2, the sick pig isolation house is 200㎡,
and the veterinary laboratory laboratory is 10㎡.
2.2 auxiliary production area
The total building area is 830㎡.
Among them, the feed processing workshop is 200㎡,
the feed warehouse (raw material warehouse and finished product warehouse) is 400㎡,
the dressing and disinfection room is 100m2, and the water tower is 80㎡，And substation control room 50㎡.
2.3 management and living area
The total building area is 200㎡.
Including 10㎡ office, 60㎡ staff dormitory, 60㎡ canteen and dining room，30㎡ meeting room and learning room;
Others (including factory director room, accounting room, etc.) 40㎡
2.4 equipment purchase
Including: 29-1000 feed machines, 2 Cake crushers, 2 pellet feed machines, 280 delivery beds, 280 nursery beds,
20 hand-propelled feed trucks, 20 septic trucks, 6 hot-air stoves, 1 passenger and cargo truck and 1 tool truck.
Including: 1 field manager, 1 Laboratory, veterinary , 1 accountant , 1 keeper and cashier, and driver.
There were 1 person, 8 feed production workers, 2 artificial insemination, 10 breeders,
1 boiler worker, 1 electrician, 1 cook and 2 guards, a total of 30 people.
4.1 production process
Pork is produced according to the modern industrial production mode, and the production line process is implemented Namely;
breeding → pregnancy → delivery → lactation → breeding → fattening → sales.
Form a line Continuous flow production line,
planned and step-by-step arrangement of pig production throughout the year.
Production process description:
① Breeding boars are raised in a single pen and limited in semi closed pig houses;
② Empty sows, including young reserve sows and weaned sows, are raised in semi enclosed houses;
③ The sows were inseminated in 7-10 days after weaning;
④ After fertilization, they enter the single pen pig house and carry out pregnancy observation about 28 days.
It is found that the estrous sow is inseminated again;
⑤ The pregnant sows were fed in limited amount and transferred to the litter house after 79 days;
⑥ The nursery is a unit type fully enclosed room, with 10 delivery beds per unit and limited feeding;
⑦ The suckling pigs were weaned after 28 days and transferred to the empty house;
⑧ After weaning, the suckling pigs were transferred to the nursery for 30-40 days;
⑨ And then transferred to the fattening house for 120-150 days.
4.2 technical indicators
The technical indicators reflect the advanced level of the proposed pig farm.
Among them, the conception rate of sows in estrus was more than 95%;
Sows produce 2 litters per year; 8.1 piglets survived in the first litter;
The sows survived 10-11 piglets;
The piglets were weaned at 35 days of age, and the weaning weight was more than 6kg;
The body weight of piglets reached more than 16KG at the age of 70 days;
The body weight of meat pigs reached more than 110kg at 185 days;
The daily gain of meat pigs in fattening period is more than 700g;
The ratio of weight gain and material consumption in fattening period was 1:3;
The meat receiving rate of pigs is more than 60%.
4.3 main technical measures
4.3.1 select excellent hybrid combinations.
4.3.2 piglets are weaned at 28 days.
Early weaning can increase the annual litter size of sows.
The annual production of piglets and the number of slaughtered pigs are conducive to disease control.
Early weaning enables suckling pigs to eat nutritious full price compound feed as soon as possible.
As long as they master the technical essentials and feed properly, their growth performance is slightly higher than that of non early weaning piglets,
and their non benign growth in the early weaning period can be compensated in the later compensatory growth.
Due to early weaning, the annual output of sows can reach 2 litters.
4.3.3 underground pipeline is used for heating. Underground pipeline heating,
the heat source from below, is very beneficial to the health of pigs, but the disadvantage is high cost, once damaged, it is difficult to repair.
4.3.4 breeding pigs shall be fed in a limited amount and meat pigs shall be fed freely.
4.3.5 water supply of nipple type automatic water diverter.
The height of the water diverter from the ground is 80cm for breeding boars, 70cm for sows, 50-60cm for finishing pigs,
70cm for sows in delivery houses, 10cm for piglets, and 30-40cm for piglets in nursery houses.
On the one hand, the investment estimation reflects the quality of the design report of the pig farm,
and on the other hand, it can be compared and demonstrated with the economic strength and production conditions of the pig farm,
To determine whether the design is feasible. 20000 lean pigs were slaughtered annually, and the total investment of the pig farm was 22.7 million (¥).
Various investments are as follows:
5.1 fixed investment: 11.2 million（¥）.
5.2 current investment: 11.5 million（¥）.
