Animals weighing 60 kg at the age of 124-170 days are taken for feeding. Nowadays feeding in a pig farm lasts 2 months. Products that negatively affect the taste of pork and fat are completely excluded from the diet. For example, the content of meat production feed, soybeans, corn, bran, oats, cattle cake, potatoes, pulp, beet pulp, distiller’s dried grains is reduced to 5%.
The first period lasts from 4 to 6 weeks. The basis of the diet: a mixture of grains (5.5 kg), 2 kg of bran, 15 kg of succulent feed (roots, pumpkin, zucchini, beet). The second period lasts for up to a month. The emphasis in feeding is shifted to the increase of coarse grain fibers, fiber. After all, the less feed enters the stomach, the faster the physiological reactions of accumulation of subcutaneous fat and lard (intrauterine fat).
The third period lasts 3 weeks. Animal feed is completely removed from the diet.
The total diet in percentage is as follows:
- simple carbohydrates (sugar) and easily digestible starch - 50-60%;
- succulent feed - the first period (30%); the second and third - 10%;
- dry mixes - the first period (15%); the second period (40%); the third period (25-30%).
Yeast hydrolyzate has a positive effect on the organoleptic properties of lard and meat, such preparation also increases the average daily gain of the animal.
But the most proven way is the introduction into the diet of a specialized feed concentrate AVAMIX - Finish 10% - protein-vitamin-mineral supplement (PVMS) for pigs weighing 65-110 kg. The recipe of supplement fully satisfies the physiological needs of the animal during feeding. High-quality vegetable protein, mineral supplements have a positive effect on the organoleptic characteristics of the finished product.
The approximate diet using PVMS is as follows.
