The nutrition of weaned piglets is the foundation for their subsequent growth performance

Whether it is from improving the slaughter rate of pigs, from the uniformity of piglets, or to reducing the time of growing pigs, everything starts with piglets, and from the moment of birth, it should be well managed. During the suckling period of the piglet, we will add some teaching material to it to promote gastrointestinal development and prepare it for feeding. After weaning, the piglets start to feed the feed. At this time, the nutrition is very important and it is the foundation for the growth performance of the piglets.

Improved broiler pigs need to be tested for their nutritional regimen to ensure that growth efficiency is maximized and the target carcass is desirable. At present, in order to meet different needs in Eastern Europe, the breeds of pigs are relatively diverse. There are both modern and traditional breeds, so a flexible feeding plan is critical. The focus of the area is on finding the best feeding plan. However, for any one place, the right feeding method to increase the growth performance of pigs (having maximum genetic potential) should begin with the use of sucker/feeder feed.

The quality of the suckling piglet/feeder's feed is crucial for the pig's optimal growth performance.

1 Early feeding

We hope that piglets can feed immediately after weaning, and hope that they will feed more weaning diets to maintain a good intestinal environment. The feed intake of weaned piglets depends on the quality of the diet (whether it is well digested). Piglet diets should be kept in a fixed formula to ensure that they have the same dietary preparation at each meal. Only through the test proved that the formula change can improve the pig's growth performance, can implement a new feed formula.

It is especially important that the method of processing the feed for piglets/feeders must be correct in order to ensure that the heat-sensitive milk proteins in the feed are not damaged. Because of the extra care required in the production process, although only a very small amount is produced per hour, many piglets' feeds are produced in specialized processing plants. Such an environment can ensure good feed quality.

A study reported in 2008 showed once again that the quality of the roughage is critical to the performance of the piglet after weaning. The study compared seven different sources of whey in the corn/soybean meal diet compared to the untreated control group. The amount of whey added was 10%, the test period was l4d, and feeding was started on the fifth day after weaning. The results showed that piglets fed different sources of whey have different growth performance. Although, on average, pigs fed whey diets had a 10% increase in average daily gain compared to control pigs, pigs fed two sources of whey gained an increase of l8%, and they consumed The daily gain of piglets from both sources of whey increased by only 4%.

2 High quality whey ingredients

At the end of the 14-day trial period, pigs fed different whey sources performed differently, with the best group of piglets gaining 570 g of extra weight gain. This trial emphasizes the importance of identifying high quality whey and gives a good reason to explain why piglets at the early weaning stage chose food grade whey as a feed ingredient. It should be noted that not only the quality of the milk protein is required to pass, but also the quality of all other components in the suckling piglet/feeder's feed is ensured so that the newly weaned piglets avoid slow growth.

The effect of post-weaning roughage quality and specialized production requirements can be used to explain why in many Eastern European countries, sucker and piglet feeds are usually imported rather than produced locally. To ensure that the required feed is purchased, it is necessary to look for places where high quality roughage can be easily obtained and suppliers who provide feed are registered suppliers.

All piglets/feeders should be digestible. Cooked cereals, high-quality fishmeal, and milk proteins can all ensure improved feed digestibility and thus increase piglet growth performance at a later stage. The use of these raw materials can reduce the number of piglets that are sick, reduce the elimination rate, and reduce the difference in weight of pigs at the end of nursery.

In this study, digestible feeds reduced the percentage of pigs that were segregated to sick pigs or who were going to die by 94%.

High digestibility can reduce the difference in weight between pigs. The difference in body weight is an important indicator to consider when piglets are transferred to a finishing house. The smaller the difference in body weight of piglets during the swarm, the more correct the feeding scheme. At the same time, we should expect that the weight of the pig will remain small until the time of slaughter. This will ensure that when the market demands, selling a larger number of pigs at the same time to achieve a considerable profit.

Pigs fed with higher digestibility feeds had an average of 410 g more than pigs fed conventional feeds. After 1 1 d, all pigs were fed a standard diet until the end of the nursery period. The final results showed that the average body weight of pigs fed the higher digestible sucker/pig feed increased by 2.25 kg. Obviously, the importance of the quality and digestibility of the piglets after weaning is not only to meet the early needs of the piglets, to avoid damage to the digestive system and the immune system, but also to bring benefits to the entire conservation period.

3 Management is still the key

However, if there is no proper feeding and management, the superiority of feed quality will not be exerted. For example, many producers in Eastern Europe often say that they are reluctant to use composite diets during the piglet conservation phase. During the entire nursery period, they prefer to use 1 or 2 pre-weaning piglets. They did not realize that such a simple and simple feeding scheme would endanger the performance of piglets after weaning, thus increasing the cost of feeding. The dietary requirements of the piglets vary with the age of the month. The use of compound feeds in piglet nursery is the only feasible way to adapt to this change.

Therefore, the use of a good quality feed for piglets/feeders provides a good basis for the growth performance of the piglet - "good start, good end" - providing good management of pigs and good feeding programs.

The editor has something to say:

1 The composition of diets for different breeds of pigs should be different. Each breed of pig has its own growth and development rules different from other breeds, so its demand for nutrition is different. At present, most of the full-price materials in the domestic market do not have subdivided demand for varieties, but are based on an approximate nutrition plan. Therefore, feed companies still have a long way to go. They should study the needs of different stages of pigs for different nutritional needs and subdivide the feed.

2 The article emphasizes that in the early feeding period after weaning piglets, high-quality whey powder is added. The current domestic piglet's teaching material seems to have been added, as well as aromatics and the like, but the price is more expensive, and 10 are good. A pound of money, do not know what users are using what material.

3 Many pig-raising colleagues in Taiwan removed the sows after they were weaned. The piglets were fed a few days of artificial milk in the delivery room before they were transferred to the nursery. It was not known how our netizens did in this respect.
