Technical Field

The invention belongs to the technical field of pig feed, and relates to a high-fat piglet creep feed and a preparation method and application thereof.

Background

After weaning, under the influence of stress factors such as nutrition, psychology and environment, the piglets often have weaning syndromes such as diarrhea, low feed intake, growth obstruction, immunity reduction and high mortality. The high-quality creep feed is an important guarantee for the success of weaning of piglets.

The piglets grow fast and have high energy demand. Fat is the most effective energy source, the physiological energy value of the fat is about 2.25 times of that of protein and carbohydrate, the metabolic energy value is high, the heat consumption is low, and the fat has an additional heat energy effect. The fat is added into the feed, so that a relatively high energy concentration can be provided by a relatively small formula space, the requirement of part of livestock on high energy can be met, the concentration of other nutrient components can be increased, and the application effect of the fat in the piglet creep is not ideal. Because the digestion of fat in breast milk by piglets is greatly different from that of animal or vegetable fat in the diet, and the fatty acid composition of breast milk is greatly different from that of animal or vegetable fat, the fatty acid has an important influence on fat utilization and total nutritional value, and particularly, the length of the fatty acid chain, the saturation degree of the fatty acid, functional fatty acid and the like all influence the utilization of fat by piglets. Therefore, finding the optimal fatty acid composition suitable for intestinal tract digestion of weaning piglets and improving the utilization rate of the weaning piglets on the fatty acid is the problem to be solved at present.

The digestibility of the piglets to the milk fat is more than 95 percent, but the utilization of the piglets to the fat in the diet and the utilization to the milk fat in the breast milk have a great difference. At present, the fat content in the creep feed is generally 3%, and the fat content in the creep feed can cause the piglets to produce fatty diarrhea and the piglets can not absorb the exogenous fat with too high content, so that the energy intake of the piglets is limited, and the growth of the piglets is influenced. For example, although the milk powder for piglets disclosed in CN104686857A may contain fat of about 12%, the fat of the milk powder for piglets is only from the expanded soybean, vegetable oil (such as coconut oil, soybean oil, etc.), and a small part of the fat is from whole milk powder and medium milk powder, and the composition of the fatty acid of the milk powder for piglets cannot reach the optimal fatty acid composition suitable for intestinal digestion of weaning piglets, so that the utilization rate of the fatty acid of the weaning piglets is low, and the special nutritional requirements of the piglets cannot be met.

CN108378235A discloses high-fat piglet milk powder, which comprises the following components in percentage by mass: 15 to 35 percent of protein component; 25-40% of fat component; 30 to 45 percent of carbohydrate component; 0.5 to 1 percent of vitamin component and 1 to 5 percent of mineral component. The milk powder for the piglets provided by the invention has high fat content which can reach 25-40%, is easy to digest and utilize, can fully meet the high fat nutrition requirements of the piglets, and does not cause diarrhea. However, the piglet milk powder provided by the invention is high in cost, more piglets with special nutritional requirements are provided in the using stage, the popularization and the use of the piglet milk powder in a farm are limited due to high price, in addition, the piglet milk powder provided by the invention is powdery, the raw material absorption rate is not high, the powdery milk powder is easy to waste and causes the piglets to suffer from respiratory diseases, and therefore, the development of a high-fat piglet creep feed is urgently needed, the nutrition income of the piglets is improved, the nutritional requirements of the piglets are met, and the rapid growth of the piglets is further promoted.
