Pig users should do everything possible to do a good job in feed mix, reduce production costs, so as to reduce their own investment and improve pig income. What principles should be followed in the formulation of pig feed?
1. The nutrition is suitable. In the formula, the balance of nutrition levels is achieved, especially the balance of amino acids.
2. The size is moderate. We should pay attention to the relationship between pig's feed intake and feed volume. If the pig's feed volume is too large, it can't be eaten completely. If the pig's feed volume is too large, it is easy to cause sagging.
3. High quality and low price. According to the needs of production, the grade of compound feed should be improved, and the formula should be adjusted at any time according to the change of market price, so as to obtain economic benefits.
4. Diversity. In order to play the complementary role of various substances and improve the utilization rate of feed, a variety of feeds should be reasonably mixed.
5. Crude fiber content. No more than 3% of piglets, no more than 6% of growing pigs and no more than 12% of breeding pigs.
6. Palatability. The one with good palatability should be used more, and the one with poor palatability should be used less.
7. Flexible application. The suitable feeding standard and feed composition were selected to observe the growth, development and production performance of pigs through feeding test, and then to modify them as appropriate.
8. Health indicators. Moldy and toxic feed is prohibited.
When premix is used, it can't be added directly, but the ratio dilution method should be used, and the mixing must be even. The replacement of premix should be carried out step by step. Sudden replacement of premix may not be suitable for pigs, which may affect feeding and growth. Following these principles, I believe that farmers will raise healthy pigs with less investment.
