How to fatten pigs quickly, how to fatten pigs quickly

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.

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.

1. Egg white injection method.

Fresh egg whites (fertilized eggs are preferred) are injected into the thyroid gland or sides of the submandibular glands under the neck of the pig. Suitable for pigs weighing more than 50 kg, each pig can use the egg white of one egg, injected 1 2 times a week. After injection, pigs love to sleep but do not like to move, and the daily weight gain can reach 1 5 kg.

2. Piglets promote the "three-needle method".

First injection: 7 days old, gram of intramuscular injection with vitamin B12 behind the ear.

Second injection: 14 days old, intramuscular injection of vitamin B12 behind the ear.

The third injection: 30 days old, with 1 ml of vitributin calcium, 20 mg of triphosphate gland, intramuscular injection behind the ear.

After three injections, the piglets love to eat and sleep, ** ruddy, and the coat is shiny. It can weigh up to kilograms on 60 days in summer and 16 kilograms on 60 days in winter.

3. High-efficiency growth agent method (i.e., high-efficiency active amino acid solution).

Raw materials: 1 kg of pig hair, chicken feathers, and human hair, washed, removed, and dried.

Method: A large iron pot (can be filled with 40 kg of water), add kilograms of water, boil (100) over high heat and put in the above raw materials, then add 500 grams of A3 decomposition alcohol (available in stores), boil for 5 minutes, wait for full dissolution, concentrate and dry, filter and bottle for later use.

Dosage: 50 kg body weight fed 8 10 grams, mixing, continuous feeding.

Effect: Medium pigs (50 kg) can gain up to kilograms per day. The skin is red and the hair is bright, and he likes to eat and sleep. The piglets are effective in 7 days. The above dosage can be used by 10 to 15 pigs throughout the feast.

4. Red light irradiation method.

1 15-watt red bulb per square meter, 1 meter high from the ground, 12 hours of irradiation per day, fast growth rate, feed utilization rate can be improved.

5. **Fertilization method.

1. In the fattening stage, the amount of pig intake macro spike will increase, which is the fastest stage of pig growth, if this stage of feeding management is appropriate, it will speed up the growth rate of young pigs, improve their own immunity, and lay a good foundation for early slaughter.

2. Generally speaking, the feed cost of fattening pigs accounts for about 70% of the total feed cost of the pig farm, the maximum feed intake of Wang Qi pigs in the fattening period, the conversion rate and utilization rate of feed directly affect the efficiency of the pig farm, the pig feed at this time can not be greedy to save money, the key is to control the quality, choose a reasonable fattening pig feed, good fattening pig feed can meet the nutritional needs of fattening pigs, and eat less, grow fast, and not fat.

3. Before the pigs are transferred to the fattening house, preparations should be made. First of all, it is necessary to disinfect the enclosure and clean it thoroughly, and secondly, it is necessary to do a good job of vaccination and deworming.

4. In the fattening pig stage, in order to improve the overall uniformity of slaughter, we should try to ensure that the fattening pigs can be slaughtered in the same period to avoid uneven size and inconsistent growth rate. It is necessary to pay attention to the density of the fattening pig house, and the number of pigs in each group should not be too much, depending on the area of the enclosure and the feeding density. The number of heads per circle should be 10-20.

However, the exact number can vary depending on different environmental conditions. Feed intake, feces, and mental state of pigs are often observed, and the disease is isolated in time**, and it is prevented in large groups.

Scientific feeding: Increase the proportion of corn in the feed to 70% and add 1% vegetable oil. Light temperature control:

For fattening pigs, red light is exposed to red light for 12 hours a day, and the temperature is controlled at 18-23 degrees. Add growth promoters: Add growth promoters to the feed.

Pig blood transfusion: Fresh blood from healthy pigs is transfused to pigs, to which the anticoagulant sodium citrate is added.

1. Scientific feeding

During the feeding period of fattening pigs, in order to quickly fatten, the proportion of corn in the feed should be increased, preferably above 70%, and 1% vegetable oil should be added to it to meet the growth needs of fattening pigs, and 15% of fishmeal can be added to the piglet feed to improve the protein content and increase the daily increment of pigs.

2. Light temperature control

Pigs in the fattening stage, to be 1 meter high from the pigsty, a 15-watt red bulb per square meter, for the pig to irradiate red light for 12 hours a day, the daily weight gain can be increased by nearly 2 times, and the temperature of the pig house should be controlled between 18-23 degrees, when it is lower than 18 degrees, put bedding to keep warm.

3. Add growth promoters

In order to make the rapid development of fattening pigs, it is recommended to add high-quality growth promoters when feeding, while increasing weight, can effectively resist pathogens, fattening pigs that eat growth promoters, show gluttony, snooze, feces less symptoms in the early stage, and have the characteristics of wide back, plump buttocks and more weight gain in the later stage.

4. Inject pig blood

When fattening pigs in fattening, you can collect fresh blood from healthy pigs, add 5 ml of anticoagulant sodium citrate per 100 ml, calculate 2 ml per kilogram of body weight for each blood transfusion, and transfuse blood every 7 days, which can effectively accelerate the development rate of pigs, and the effect is particularly significant.

1. Pig farm fattening pigs is an important economic benefit, in the whole fattening stage, the core of feeding is to control feed costs, improve feed utilization, and accelerate the growth of fattening pigs, which requires efforts in feeding management.

2. If the amount of pig manure and urine in the fattening stage is large, the hygiene in the pig house will become poor, and it is easy to breed a large number of bacteria and cause various diseases. Therefore, in the early stage of the construction of the pig house, it is necessary to do a good job of the slope of the ground, easy to drain, urination, the slope should be moderate, and the feeding density should also be controlled, so as to increase the rest area of the pig herd and let the pigs fully gain weight. Environmental control and disease prevention and control need to implement the principle of all-in and all-out for fattening pigs, and sick pigs can release the source of disease through the respiratory tract, digestive tract and secretion system, so that the virus can breed in the pig house; Therefore, after all in and out, let the pig house have a certain empty period, and the pig house will be fully cleaned and disinfected during the empty period, and then disinfected by disinfectant, and left vacant for about a week.

Pig farms in self-breeding and self-raising to save a lot of pure rough unnecessary trouble, piglets need to be grouped after weaning, pigs should be grouped according to the breed, gender, weight and eating and other conditions, so as to facilitate the uniformity of the pig herd, reduce the occurrence of fighting, biting, for weak physique, poor eating pigs are fed separately, timely observation of pig feeding, defecation and drinking water.

In order to raise fattening pigs well, it is necessary to choose good breeds and the best cross combinations. The ternary crossbreeding, that is, the binary sows produced by Landrace Yorkshire crossbreeding, and then the piglets produced by Duroc as the terminal paternal parent, are internationally and domestically recognized as excellent fattening pigs. Each farm can be determined according to its own economic strength:

With strong strength, you can use the introduced foreign breeds to use the foreign ternary piglets of Du Chang and Du Da Chang for fattening. Or go to some large-scale pig farms to buy three-yuan piglets for fattening. If the economic strength is poor, you can use the local excellent sows to cross with the introduced pig breeds, and use the hybrid offspring such as Changben and Du Daben to produce commercial pigs, which are called soil ternary.

Or go to some small-scale, cheap pig farms nearby, buy three-yuan piglets for fattening, but try not to buy piglets in the bazaar, so as not to be infected with infectious diseases, resulting in economic losses.

The proportion of crude protein provided by soybean cake, bran, fish meal, etc. in the diet should be 15% 16% before the weight of the pig is 50 kg; After 50 kg, it should account for 12% and 13%. In the fertilization stage, corn, sweet potatoes and other starchy energy feeds can be fed. In addition, it is necessary to provide sufficient drinking water, feed and water 2 3 is appropriate.

The timing of fertilization should be appropriate.

The fertilization time can be determined according to the variety, weight and age at slaughter. Local early-maturing pig breeds, weighing 35 to 45 kg can be fattened, and large late-maturing pig breeds should be up to 60 kg to start fattening. At this time, fattening pigs have a strong appetite, ** ruddy, shiny coat, and snooze after eating, which is the most suitable fattening period.

At this time, it is easy to grow large pigs and save feed. When fattening pigs grow to a certain period, their growth gradually slows down, feed consumption increases, and weight gain decreases, so it is not cost-effective to continue fattening. Medium-sized pigs gain the fastest at 50 to 90 kg and should be slaughtered when they reach 90 100 kg.

Large pigs should not exceed 110 kg when slaughtered. It is best to weigh and calculate feed remuneration regularly in order to achieve the best economic results.
