How to raise pigs to grow and fatten quickly, and how to fatten pigs quickly

Every family in the countryside raises pigs, but due to the small scale and unscientific feeding methods, it affects the economic benefits of pig raising. After years of practice, the center has summarized the rapid fattening method of pig raising suitable for rural areas, which is introduced as follows:

First, the purchase of excellent piglets. Rural families raise a single breed of pigs, which is relatively backward, and it is necessary to select excellent piglets with good quality and rapid growth.

2. Scientific management. The purchased piglets must be epidemic prevention as required, and then castrated, and regularly dewormed, selenium, iron, etc. There must be a good pen, the pig house must be warm in winter and cool in summer, so that the pigs can grow and develop normally. The pig house should be disinfected regularly and the bedding should be changed frequently.

3. Scientific feeding. The pigs are fed different feeds according to their different growth stages.

After weaning to 3 months of age, piglets need 18%-20% of beans (raw soybeans fried and crushed), 20-22% of bran, about 60% of corn (crushed), 3% of fish meal, 1% of bone meal, and appropriate amounts of selenium-containing auxin, artificial salt, and multivitamins per 100 kg of concentrate. After 3 months of age, roughage can be added in moderation, gradually added to the concentrate, slightly increased every month (add a small amount of baking soda when feeding pigs). Feed pigs to be timed, quantitative, piglets to eat less and more meals, gradually reduce the number of times later, feed the material is now wet with water, the ratio of material and water to hand grasp into a ball.

Pay attention to disease prevention, in addition to doing a good job of epidemic prevention, can not feed moldy and spoiled feed, usually pay attention to observation, if you encounter adverse situations, you should be timely **, improve the survival rate.

Add some baking soda, saccharin, citric acid, calcium formate, flavomycin to the fed feed.

1. Feed baking soda. Adding baking soda to the pig feed lacking lysine can make up for the lack of lysine, and is conducive to the digestion and absorption of crude fiber, improves the utilization rate of feed, and promotes pigs to grow more meat and gain weight quickly.

2. Feed saccharin. Feeding pigs with an appropriate amount of saccharin has a better effect on weight gain. Method:

Add grams of saccharin per kilogram of compound feed, dissolve saccharin in water and then mix into the feed when feeding, which can increase the feed intake of pigs, increase the daily weight gain by 7%, and reduce feed consumption and cost per 100 kilograms of pigs respectively.

3. Feed citric acid. Adding citric acid to pig feed can increase the palatability of feed, improve the digestion and absorption of nutrients by pigs, and improve the conversion rate of feed. Adding 30 grams of citric acid per kilogram of feed can increase the pigs from 189 grams to 216 grams per day, which is most suitable for feeding weaned pigs weighing 5 kg to 10 kg.

4. Feed calcium formate. After weaning piglets, adding calcium formate to the feed in the first few weeks can increase the growth rate of piglets by more than 12%, increase feed conversion by 4%, improve weight gain, and reduce the incidence of piglets.

5. Feed flavomycin. Starting from the pig to 35 kg, adding flavomycin to the feed can increase the daily weight gain of pigs by 7%, the feed conversion rate can be increased by 5%, and the amount of flavomycin added: 20 mg per kg of feed for piglets, 50 mg per kg of basal diet for fattening pigs, and 250 mg per kg of mineral feed, the effect is significant.

Pig growth cycle:

The pig growth cycle is 4-5 months, and there are three periods for the growth and development of pigs, namely lactation, nursery and fattening. The key points of feeding management during lactation are: in the first 3 days of birth, let the piglets eat enough colostrum, do a good job to prevent the sow from being pressed, and do a good job of keeping warm.

At the age of 5-7 days, the piglets are fed and gradually fed, so that the piglets can transition from recognizing to eating, and transitioning to complete feeding at weaning.

<> regular and quantitative: feeding pigs needs to be specified for a certain time, a certain amount of feeding and a certain number of times every day, which can improve the appetite and digestibility of pigs. First refined and then green:

When the pigs are fed, feed the concentrate first, then feed the green feed, and do less to add the diligently, generally each meal is divided into 3 feedings, so that the pigs can eat within half an hour. Raw feeding is better than cooked feeding: raw feed is more nutritious, and pigs eat less and grow faster.

1. Timing and quantification

1. Feed pigs every day to specify the time, feeding amount, number of times, so that pigs develop good living habits, eat well, sleep well, will grow fast, can effectively improve the gastrointestinal function of pigs, as well as appetite and digestibility, piglets are regularly fed 4 meals, fattening period regularly fed 3 meals.

2, the pig's appetite, generally in the evening is more vigorous, followed by the morning, weaker at noon, in the summer this trend is more obvious, so in 1 day each feeding amount, can be distributed according to the following proportions, 35% in the morning, 25% at noon, 40% in the evening, generally speaking, the pig can be fed 9 full, if overfed, it will affect the appetite of the pig for the next meal, resulting in excess of food.

Second, the first refinement and then the green

1. When the pig is fed, first feed the concentrate, and then feed the green feed, and at the same time to do less diligent addition, generally each meal is divided into 3 feeding, so that the pig eats within 30 minutes, when the pig does not want to eat, it is necessary to feed each pig green feed, if it is no polluted green feed, generally do not need to wash or chop, can let the pig bite to eat, so that the saliva and green feed can be fully mixed with the bucket to rise, can increase the pig's appetite.

2. Concentrate feed is a more comprehensive compound feed, rural farmers can match according to local conditions, such as rice, corn, barley, wheat, sorghum and sweet potatoes, etc., and then add protein feed, such as peanut cake, soybean cake, vegetable cake, sesame cake and cottonseed cake hail and other matching feed, can be called concentrate feed.

3. Raw feeding is better than cooked feeding

The nutrition of raw feed is more comprehensive, pigs eat less, grow fast, labor-saving, time-saving, fuel-saving, feed-saving, if the raw feed is cooked and fed with a pot stove, not only consumes a lot of labor and fuel, but also increases the cost of pig raising, the labor is old and old, the efficiency is low, and at the same time after high temperature treatment, it will cause the loss of nutrients in the feed by about 10%, if it is not cooked well, it will also cause nitrite poisoning, resulting in the death of pigs.

1. Timing, quantitative, and fixed, do not change with the state's faith, and develop a fixed conditioned reflex, which is conducive to the digestion and utilization of feed.

2. Feed amount. It is better to feed the pigs three times a day, and those under 25 kg can be fed four times a day. The feed amount is the weight of the pig.

Small pigs should be appropriately more, and large pigs can be appropriately reduced. In practice, the method of mastering the amount of pig feeding is summarized in 8 words: that is, "eat enough, do not lick the feeding trough".

Let the pig be full and have no leftovers, and the sign of being full is not to lick the feeding trough, and the remaining slag is a sign of not licking the feeding trough.

3. Feeding method. The feed required for each pen should be evenly spread from one end of the pure wheel of the trough to the other. This allows for an equal feed for each pig. It is more conducive to the timid pigs who can't grab the groove from both ends to eat the feed, so as to prevent individual pigs from losing weight.

4. Clean the feeding trough before feeding. Be sure to remove the manure and urine in the trough before feeding, and never spill the manure with it. After the pigs are full, the leftovers are cleaned to prevent contamination and waste of feed.

5. There are many forms of feeding for fattening pigs, mainly thinner, wet mix and dry material. Feeding too thin feed will weaken the chewing function, dilute the digestive juices, and also affect the feed intake of the pig, affecting the weight gain. It is easy to appear "straw belly", and it is lowered out of |meat rate; The wet mixture is mixed with 1 times the water, and it is advisable to hold the feed exudation water, which is conducive to the swallowing of food and can complete the feeding work quickly; Raw dry material can prolong the time of food chewing in the mouth, so that the food is mixed with digestive juices, which is conducive to improving the output of fattening pigsMeat rate, popular in the hog market.

6. Timely material change. The feed of fattening pigs is divided into piglet feed, which is fed before 30 kg; Medium pigs are fed with 30 kg and 60 kg, and large pigs are fed at 60 kg to the slaughter stage. Changing the feed on time can not only adapt to the needs of the different stages of the fat pig, but also reduce the cost of feed.

7. Maintain the uniform growth of the pig herd. After a period of pig breeding, there are often relatively thin or suffering pigs in some pens, so it is necessary to timely transfer the pigs in each circle who are thin and can not grab the trough, and concentrate on transferring them to a pen to strengthen feeding and management. The pigs are to be put into the empty pens and concentrate.

In this way, the pigs can recover quickly, avoid the formation of stiff pigs or cause death, and be slaughtered on schedule.

How to fatten pigs quickly|Pigs are fattened quickly.

Provide a dry, comfortable and temperature-friendly production environment for pigs, maximize their genetic potential for growth and development, reduce or eliminate diseases, reduce mortality and culling rates, and obtain optimal weight gain.

2.Environmental control.

Temperature and humidity: The temperature and humidity of the pig house are the main environment for fattening pigs, which directly affects their weight gain rate. Pigs at different stages have different temperature requirements.

For pigs weighing 11-45 kg, the optimum temperature is 21; For pigs of 45-100 kg, the optimum temperature is 18; For pigs of 135-160 kg, the optimum temperature is 16. Under the optimal temperature conditions, the humidity has little effect on weight gain, and the suitable relative humidity of the pig house is about 50.

Light: Light has no significant effect on the mouth weight gain and feed conversion rate of pigs, as long as the light in the fattening house does not affect the feeding of pigs and is easy to manage. The light should not be too strong, too strong light can reduce the weight gain of the mouth, and the consulans are thinner.

Ventilation: The pig house should be ventilated frequently to drive away dust, odor, ammonia smell and keep the air fresh. Modern, high-density pigs and enclosed barns need to be ventilated all year round.

However, it is necessary to pay attention to solving the contradiction between ventilation and heat preservation. Dispose of feces, urine and dirt in a timely manner.

Captive density: captive density directly affects the herd behavior of pigs, generally the higher the density, the more serious the impact on the weight gain and feed conversion rate. When the density is high, the local temperature in the pen rises, resulting in the loss of appetite and feed intake of pigs; possible accumulation of subclinical diseases, a decrease in the health of pigs; Conflicts between pigs have increased, the strong have taken the weak food, and the group living environment has deteriorated.

In general, each growing and finishing pig accounts for 2 meters, each pig stage accounts for 2 meters, and each pig stage accounts for 2 meters.

3.Quality feed management.

Straight line fattening to concentrate feed, the whole fattening period feed changes little, always maintain a reasonable level of nutrition, and hanger fattening in the hanger period to green, concentrate feed-based, low nutritional level, the use of thin soup to fill the belly feeding method.

4.Add feed additives such as high-quality fertilizer such as feed probiotics.
