For meat production, the choice of the pig breed is important. If the animal quickly gains kilograms with normal care, then this allows you to provide the family with a tasty meat product in a short time. It is not for nothing that a Vietnamese pig is raised, the weight of which at 6 months is about 50-60 kilograms, and by the year it is almost a centner.
The importance of weight control
Vietnamese pot bellies have gained popularity due to:
- rapid puberty;
- delicious and tender meat;
- strong immunity;
- unpretentious content.
If this breed of pig is raised, then they must be able to control weight gain. Pay attention to the mass of piglets just born. Both underweight and its rapid increase indicate health problems in the female. Piglet weight gain is monitored monthly. You need to know the norms of weight in order to determine why there is a slow growth of muscle mass. Everything plays a role: appetite, content, number of hours of sleep, activity of behavior.
Weight loss often indicates that the piglets have worms or have an infection.
Up to a year, you should correctly determine the amount of vitamins and minerals when feeding. When potato useful elements are obtained in abundance, they quickly gain weight up to six months. But further recruitment indicates an increase in the amount of fat in pigs.
Average weight of Vietnamese piglets by month
It is necessary to start controlling the mass of Vietnamese piglets from the moment of birth. Babies weigh up to 600 grams, but not less than 350. If at first the cubs are fattened by natural feeding, then the weight gain depends on the food that the farmer prepares.
One mother's milk is enough for piglets for the first 10 days of life. Then comes the turn of the introduction of complementary foods. Together with mother's milk, monthly cubs are given cereals, eggs, hay. Be sure to add cereals, legumes, vegetable products to the diet, thanks to which the piglets are gaining weight. Iron injections are needed at this time. By the end of the 1st month, a newborn piglet increases its weight almost 10 times, reaching 4-5 kilograms.
When growing Vietnamese piglets, you need to focus on the average weight of 2-month-olds of 10-12 kilograms. Weight gain is not as fast as in the 1st month. If the calf continues to receive breast milk, then the complementary food ration is the same as for adult pigs.
The rapidity of mass gain at this time increases. Pig-bellied pigs mature quickly. Due to hormonal changes in the body, they get fat. Pigs gain 300-400 grams per day, reaching 15-20 kilograms by the end of the 3rd month. It is during this period that more vitamins and minerals should be included in the diet.
4 to 7 months
The weight gain of pigs from the 4th month of life increases. Livestock breeders often grow them up to 30-35 kilograms, sending them to the slaughter. It is believed that after 6-7 months of life, the Vietnamese should not be grown, it is unprofitable. Indeed, when a pig is slaughtered at 5 months, the meat yield is up to 80%. The product is distinguished by a pleasant delicate taste, a minimum amount of fat. Already after 6 months, a fat layer begins to form in the pot-bellied breed. Therefore, it is worth feeding animals for bacon.
7 months to a year
When they want to get as much meat with dense fat layers as possible, pigs are kept for up to a year. The body weight of the pot belly grows by 10 kilograms per month. Therefore, at 12 months, they receive a boar weighing more than a centner. Females may be slightly smaller.
The pigs left for breeding offspring after 1-1.5 years of life gain little weight. On average, the increase can reach 120 kilograms. It is necessary to feed adult pigs more with cereals, minimizing corn and legumes. They control how many kilograms the animals grow each month by varying the percentage of protein in the diet. After farrowing, the female loses weight, gradually catching up with its norms.
Factors affecting weight
The peculiarity of the Vietnamese breed of pigs is that their small stomach and small intestine have difficulty digesting coarse fiber. Therefore, when fattening animals, you should give them:
- steamed grain;
- fresh herbs;
- pumpkin, zucchini;
- hay legumes.
Pig nutrition must be balanced. Depending on what they want to get from the pig: meat or lard - they include a certain amount of carbohydrates, fats, proteins. All products are crushed so that they are easily digested by animals. In summer, the amount of feed is reduced, while it is increased in winter. Pregnant gilts, females during lactation are fed more intensively. To enhance appetite, adults are given fried rye or salted oats.
Better assimilation of food is facilitated by regular walking of pigs. If it is necessary to reduce the build-up of fat, then corn, wheat, barley are excluded from the diet. Keeping conditions play an important role in increasing the weight of pigs. Warm rooms with mandatory ventilation are prepared for animals. It is necessary to exclude drafts, sudden temperature changes.
Supplements containing vitamins A, E, group B, minerals, trace elements accelerate the metabolism.
Supplements containing growth promoters should not be included. Preparations impair the taste of meat, negatively affect its quality.
When a Vietnamese pig is slaughtered
Private farmers start slaughtering Vietnamese pigs after 4 months. The yield of gourmet meat will be within 80%. At the same time, the delicacy has a marble structure with thin layers of fat.
Industrial meat producers slaughter Vietnamese pot bellies after they reach the age of six months. It is at this time that 50-60 kilograms of tender meat with a minimum amount of fat are received. If you give more corn and barley, then the fat layer will reach more than 3 centimeters. The correct organization of animal nutrition affects the quality of meat.
One month before the slaughter of pigs, the nutrition should be increased. The animal is gaining weight faster, in the diet of which half is oats, wheat, corn with peas. The grain should be ground and given in porridge. So useful elements are better absorbed. Pigs that have passed the age threshold of 8 months are allowed to breed. Breeding the Vietnamese breed is profitable. Ease of care, strong immunity allows you to raise animals economically successfully.
