Pig feed is very important, we must let the pig eat full, but in the case of pig equipment, because of the unreasonable use, there will be waste, feed waste, the reasons are as follows: first, there is no monitoring of the effect of feed use, that is, there is no corresponding material to meat ratio data; second, people do not have a thorough understanding of feed nutrition; Third, the attention to details is not enough, ignoring the impact of details. To prevent feed waste, we should always pay attention to the use of feed in the field; at the same time, we should let all staff pay attention to the feed cost and staff wages, so that we can get more ideal results.
1. Waste of feed formula not changing with seasons
All year round, the temperature is different, and the nutrition needs of pigs are also different. But now, no matter the formula recommended by the feed factory or the formula designed by experts, it is impossible to apply it all year round. Using high protein formula in winter will cause protein waste, and using high energy formula in summer will cause energy waste. If we can adjust the formula in time to reduce the feed to meat ratio of the whole group from 3.5 to 3.4, for a 10000 head pig farm, we can save 10000 × 90 × 0.1 = 90000 kg of feed in a year, which is more than 180000 yuan if calculated by 2 yuan per kg of feed.
2. Waste of using high moisture corn without changing formula
In autumn and winter, it is often heard from pig farmers that the quality of premix or concentrate is not good, and pigs can't eat long. According to my understanding, the reason for the slow growth of pigs is not caused by the quality of premix or concentrate, but by the excessive water content of corn at that time. Due to the low temperature in autumn and winter, the energy demand of pigs is greater than that in spring and summer. At this time, most of the corn is newly harvested corn, and the water content is more than 20%. There is energy shortage in the feed. If the formula is not modified and the feed is carried out according to the fixed feeding procedure, there will be energy shortage, which will affect the normal growth of pigs. The way to solve this problem is very simple. First, increase the proportion of corn and increase the feeding amount when other raw materials are unchanged; second, when wet corn is used, it is combined with high-energy feed such as oil, which is suitable for the piglet feed or piglet feed with high energy concentration.
3. Waste of feed not processed according to formula
There are several situations, one is that the processing materials are not enough; the other is that when one kind of raw materials is lacking, it is easy to replace it with other raw materials; the third is that the raw materials are inferior, such as replacing dry corn with wet corn, etc. The above three conditions will destroy the rationality of feed formula and affect feed utilization.
4. Waste of uneven mixing
Mixing unevenness has appeared in many pig farms. It is needless to say that manual mixing is often unevenness even in machine mixing. While crushing, discharging, mixing time is insufficient. It is easy to neglect that drugs or trace additives are added to the feed, which is not directly poured into the mixer through premixing, and dozens of grams of drugs are added to the feed of thousands of Jin, so it is difficult to achieve even mixing.
5. Waste of pig feed
It is often encountered that piglets eat suckling pig feed, medium pigs eat small pig feed, and large pigs eat medium pig feed, which will cause the waste of feed. What's more serious is to let the reserve pigs eat fattening pig feed, greatly delay the oestrus time of sows, and affect the normal breeding.
