How to improve the slaughter rate of fattening pigs?

Fattening of slaughtered pigs is critical, and it is directly related to the economic benefits of pig farmers. The key is to improve the palatability of pig feed. After crushing the coarse material that is difficult to feed pigs such as bran, sweet potato vine, peanut leaves, straw, corn cob, dregs, chicken manure, etc., an appropriate amount of starter culture is added for fermentation.

After fermentation into aromatic smell, moderate sweetness and sourness, long-term storage and non-deterioration of biological food-saving feed, the use of scientific feeding methods for feeding, can not only enhance the adaptability of pigs to biological feed, but also the effect of grain saving is significant.

Use coarse fermented feed to reasonably match conventional concentrate to raise pigs, and it is necessary to feed raw food thickly, feed less frequently. In summer, it can be appropriately thinner to meet the water needs of pigs, and feed 5 meals a day; In winter, it prevents thin food from filling the belly, increasing the number of pigs urinating, and depleting pigs' body calories; It can also adjust the feeding amount of coarse fermented feed in time according to the feeding situation, and take the natural feeding of pigs as the degree to prevent the aging of the trough from affecting the appetite of pigs.

When the coarse fermented feed is immersed in cold water and soaked for several hours, and the fine slurry is filtered out with a fine steel sieve to feed the suckling piglets, a small amount of fried bean noodles can be added to the feed, and the aroma of the bean noodles can promote the appetite of the piglets. The coarse material in the sieve is mixed with concentrate and then fed to the shelf pigs. Adding sugary substances such as cooked skin, carrots, citrus peels, and sugar food scraps to the feed of weaned piglets not only likes to eat pigs, but also increases the average daily weight gain of piglets.

Under normal circumstances, it takes about six months from the newborn piglets to the last 220 catties to be slaughtered.

Under normal circumstances, the slaughter weight of pigs is about 234 catties. Some farmers will decide the slaughter time according to the local pig price, and when the pig price is very good, they will be reluctant to sell it for a period of time.

Just like the current pig price, the average is about thirteen or fourteen yuan per catty. If the farmer's pig farm is running well and there is no disease, he will generally choose to continue feeding until it is about 300 catties or even higher.

But the general slaughterhouse does not like too big fat pigs, because the lean meat rate of this pig is relatively low, more fat, if the ** is not good, this kind of pig will not be collected by the general slaughterhouse, or the ** is very low.

There is no fixed standard for fattening pigs to be slaughtered, generally speaking, more than 200 catties can be, and under normal circumstances, about 250 catties are slaughtered. It generally takes five to six months from the time the sow gives birth to the piglets to the fattening pigs are slaughtered according to about 250 catties.

Fattening pigs refer to the stage when the piglets are reared in the growing house after the nursery is completed and until they are slaughtered, which is generally a week (about 70 180 days old).

This stage is the period of the fastest growth and development of pigs, and it is also an important period for pig operators to obtain economic benefits. In the feeding management, the nutritional supply should be strengthened, sufficient and clean drinking water should be provided, and the environmental sanitation and disease prevention and control work inside and outside the house should be done to ensure the full growth and development of pigs.

The purpose of fattening pig production is to spend less feed, with a shorter time, to obtain a faster weight gain rate and more ideal meat quality, to provide people with a large number of good quality meat. So as to improve the feed conversion efficiency, slaughter rate and commodity rate of fattening pigs, and increase economic benefits.

Scientific management

In order to improve the economic benefits of pig farms and pig breeding technology, pig farms should pay attention to scientific management measures in the process of breeding, establish a sound management system, and carry out breeding work scientifically and standardly. Pig farms should also standardize and scientifically raise pigs, use automatic pig breeding equipment such as automatic pig breeding systems, provide a suitable breeding environment for pigs, improve the survival rate and growth rate of pigs, and reduce the cost of feed consumption.

Pig barn environment

The pig house environment will directly affect the quality of pigs, and then affect the economic benefits. Pig farms should be regularly ventilated, pay attention to air circulation in the pig house, and do a good job of regular cleaning to prevent bacterial breeding and infection, and prevent the spread of disease infection and influenza. At the same time, pay attention to the humidity and temperature of the pig house, reduce the impact on the feeding and rest of the pigs, so as to improve the quality and yield of pigs, 3Feed nutrition

Maximizing the feed for pigs, the economic benefits of feed are the foundation and key to the pig industry. Pig farms should be reasonably matched with feed, provide sufficient nutrition for pigs at different physiological stages, enhance the physique and resistance of pigs, and do a good job in healthy pig breeding. It is very important to reduce the cost of pig farms and improve the economic efficiency of pig farms.

Pig breeds

Pig farms should introduce disease-resistant breeding pigs to ensure the health and quality of the pig breed. Healthy and good breeding pigs can continue to grow healthily and ensure the overall breeding efficiency. Before the introduction, the pig farm should consider the specific conditions of the breeding area, select the breeding pigs with good traits and fast adaptation, avoid large stress reactions, ensure the quality of breeding, and <>

Disease prevention

In the process of raising pigs, attention should be paid to the timely prevention of various common diseases, usually through immunization. Pig farms should adopt an all-in, all-out breeding model in Shouchang, implement closed management, reduce the flow of people and vehicles, and control the spread of diseases.

If you want to maximize pig production, I think you can breed more sows so that the sows can produce piglets.

To increase pig production, you can use some food that grows pigs quickly, or you can use some cassava, which can make pigs grow quickly.

I think it's possible to vaccinate the pigs and let them eat good food, so that their productivity and birth rate can be maximized.

1. Keep the pig house quiet Let the pigs develop the habit of basically sleeping in a state of sleep within 24 hours a day, except for eating and urine, so as to facilitate weight gain.

2. Pay attention to heatstroke prevention and heat preservation In winter, the pig house should close the window holes to prevent the invasion of thieves and wind, and add bedding grass; In summer, pergolas should be erected, window openings should be opened, more green fodder should be fed, and water should be sprinkled on the ground to cool down to prevent heat stroke.

3. Do a good job in the environmental sanitation of the pig house to achieve clean food, trough clean, house clean, pig clean, and the entrance and exit of the pig farm should set up a disinfection pool. The enclosure trough is disinfected 1 2 times a month, and the piglets should be dewormed and killed for about 3 months.

4. Group feeding, according to the weight, size, physical strength and food size of the pigs, so that the pigs can only grow and develop in a balanced manner.

5. Feed crushing should be fine, mixed feed crushing should be fine, stirring evenly, in order to facilitate the digestion and absorption of the pig body.

1. Destocking of the meat market: Due to the implementation of the national policy of rapid change of meat market to destocking, many farmers have been affected by the policy, in order to save costs and reduce the number of pigs slaughtered.

3. Impact of the epidemic: Due to the emergence of the new coronavirus, the global pork market has been affected, resulting in the continuous global pig price, which has led to a decrease in the number of pigs slaughtered.

4. Fierce competition: The competition in the breeding industry is fierce, and many farmers have to reduce the number of pigs slaughtered in order to seize market share.

Usually fattening pigs can be slaughtered when about 5 months, if not slaughtered in time, the daily weight of fattening pigs will slowly decline, resulting in feed loss. Fattening pigs need to be based on their specific weight and different environmental conditions, such as a weight of 15-60kg fattening pigs should occupy an area of square meters, in the north to breed fattening pigs need to appropriately increase the feeding density, in order to achieve the purpose of keeping warm.

First, fattening pigs can be slaughtered in a few months

1. The time when the fattening pig is slaughtered.

Generally, fattening pigs can be slaughtered when about 5 months, and it is recommended that after the fattening pigs reach the standard of slaughter, they need to be slaughtered in time, because the daily weight of the follow-up fattening pigs will slowly decline, and the feed conversion rate is not high, resulting in feed loss.

2. The feeding density of fattening pigs.

1) Generally, the feeding density can be determined according to the weight of the fattening pig, such as the weight of 15-60kg fattening pigs occupy an area of square meters, the fattening pigs of more than 60kg cover an area of square meters, and the number of pigs in each pigsty is 10-20 heads.

2) But the specific feeding density should also be determined according to different environmental conditions (temperature, humidity, wind, etc.), such as raising pigs in the north, it should be appropriate to increase the feeding density, because the average temperature in the north is lower, the climate is drier, and the normal growth and development of pigs or cause diseases if the feeding density is not adjusted.

Second, what is the slaughter standard of fattening pigs

1. The standard for fattening pigs to be slaughtered.

Fattening pigs need to weigh more than 90 kg and the market price is very suitable before they can be slaughtered. Usually 90 kg of inner binary pigs, 100 kg of inner and outer binary pigs, and 110 kg of outer ternary pigs can be slaughtered.

2. How to reasonably fattening out of the slaughter.

1) Usually fattening pigs fattening time is 10-15 days, when the weight grows to 70-80 kg, the daily feeding amount rises to 5% of body weight, and the proportion of corn in the feed can be adjusted to 62%.

2) If the pig's body is lean, edible oil can be added to the feed according to the proportion of adding kilograms of edible oil per 50 kg of feed, which can promote fat deposition. However, the feeding time should not be too long, because after the fat is burned and deposited to a certain extent, the feed intake will decrease and the weight gain will be slowed down, and the fat condition will reduce the grade of the pork.
