The use of bad residue instead of part of compound feed to feed pigs can reduce feeding costs. However, if the amount of bad slag is too much, it will affect the weight gain and feed remuneration of pigs and extend the slaughter time. How to add a lot of bad residue (such as 50% bad residue plus 50% compound feed) without affecting the pig's production performance? We use a variety of scientific methods to cope with the dregs. As a result, slaughter pigs gain 5% more weight than conventional feeds, and weight gain reduces feed costs by 17% to 25% per kilogram.
Sales of pigs at 7 to 8 yuan per kilogram are more profitable for 70 to 90 yuan per pig than for conventional feed. There is no difference between slaughter rate and lean meat ratio. According to the nutritional indicators of pigs in the growing period (20 kg to 60 kg) and finishing (60 kg to 90 kg), 6 kinds of bad residue are selected: bean curd residue, beer residue, starch sugar-making corn waste, and alcohol waste liquor. Scientific cooperation. In the growing season, the combination of dregs reached 50% and 68%. The daily gain of the hog was 100% and 97% of the conventional feed, and the feed cost was reduced by 13% and 18% respectively. During the finishing period, the dregs reached 58 % and 80%, the daily gain of the hog is 128% and 116% of the conventional feed, and the feed cost is reduced by 23% and 25%, respectively.
The appropriate amount and feeding method of bad residue feeding pigs. According to the test results, we believe that the amount of bean curd residue feeding can reach 25%, but before cooking it needs to be cooked for 10 minutes to 15 minutes, or at least flushed with boiling water; beer residue or sugar can be dried or directly fed Feeding, the amount can be more than 30%; alcohol dregs can not be fed, the amount of feed is 8% to 15% is appropriate; sauce residue and dregs due to salt and antibiotics, feeding amount should be limited to about 5%.
Feeding pigs with bad food. 1. The best source of protein in bad residue is starch or sugar corn scraps. 2. A variety of miscellaneous slag mix, before the feeding to be mixed with part of the conventional feed, material and water ratio of 1:2 to 2.5, do not feed with ice or rotten fresh slag. 3. The high content of crude fiber in the bad residue affects the digestibility of the diet. When designing the diet formula, the total amount of crude fiber in the diet should be reduced as much as possible. 4. A variety of bad residue with more than 50% of the amount, dietary acidity increased, affecting the normal physiological metabolism of the pig. If you use physiological alkaline additives, hogs will achieve the desired weight gain.
We recommend each of the growing and finishing pig test formulas for selection. Growing pig formula: 25% tofu residue, 12.5% ​​starch residue or sugar corn waste, 12.5% ​​alcohol distillate, and 50% commercial pig feed; finishing pig formula: 4% soybean meal, 44% corn, 15% tofu residue 12% of beer slag, 18% of starch or corn waste, 5% of soy sauce, and 2% of bone meal. Both formulas require additional trace elements and multidimensional elements.
