Special feed for weaned piglings and preparation method thereof

Abstract

The invention especially relates to a special feed for weaned piglings and a preparation method thereof, belonging to the technical field of feeds. The special feed comprises the following raw materials: low-fat milk powder, whey powder, cicada pupa powder, soybean lecithin, wheat germs, grape pomace, mulberry leaves, leaves of Moringa oleifera, garden burnet, magnolia cortex, motherwort, medicated leaven, plantain herb, banksia rose, Osbeckia chinensis, Ailanthus altissima, fingered citron, chicken's gizzard membranes, a compound enzyme, composite probiotics and an accessory material. The special feed is directed at the particularity of the physiological structure of weaned piglings (wherein a weaning period is no more than 10 d), and a scientific and reasonable raw material ratio is employed, so the special feed can improve the adaptivity of the weaned piglings in a transition period after separation from a sow, effectively promotes the development of the digestive systems and immune systems of the piglings and directly influences the later growth vigor of the piglings; and the feed is free of any hormone, so the safety and health of the piglings are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a special feed for weaned piglets and a preparation method thereof. Background technique [0002] Weaned piglets have poor low temperature resistance, imperfect digestion, rapid growth, and lack of innate immunity. Therefore, special attention should be paid to the feeding of weaned piglets. If the feeding of weaned piglets cannot keep up, it will lead to growth stagnation and delayed slaughter. age, resulting in large economic losses. The weaned piglets are small, and the organs of the body are in the development stage. Feeding only concentrate or concentrated feed cannot meet the needs of the piglets. The shortage of trace elements will also slow down the growth of the piglets, and due to unreasonable nutrition, it will not only cause waste of feed, It increases the cost of feeding, and may also affect the immunity of piglets, causing adverse consequences and prolonging the time ...

[0002] Weaned piglets have poor low temperature resistance, imperfect digestion, rapid growth, and lack of innate immunity. Therefore, special attention should be paid to the feeding of weaned piglets. If the feeding of weaned piglets cannot keep up, it will lead to growth stagnation and delayed slaughter. age, resulting in large economic losses

The weaned piglets are small, and the organs of the body are in the development stage. Feeding only concentrate or concentrated feed cannot meet the needs of the piglets. The shortage of trace elements will also slow down the growth of the piglets, and due to unreasonable nutrition, it will not only cause waste of feed, It increases the cost of feeding, and may also affect the immunity of piglets, causing adverse consequences and prolonging the time for slaughter

[0003] At present, with the development of animal husbandry, China's pig production is gradually developing in the direction of scale and intensification, and the weaning age of piglets is gradually reduced from the traditional 60 days to 35 days. The weaning age of pig farms with higher technology is about 21 days. Early weaning of piglets can increase the reproductive rate of sows, reduce the transmission of diseases from mothers to piglets, and improve the growth performance and carcass quality of piglets during the growth period. In order to improve the growth performance of piglets, farmers gradually reduce the weaning age reasonably. However, due to the physiological growth performance of piglets, the weaning syndrome of piglets is becoming more and more obvious, especially within 10 days after weaning. Pigs are separated and rely on their own development to adapt to the critical period of the new dietary structure. At this time, the digestive organs of the piglets are not yet mature, the functions are not perfect, and the activity of digestive enzymes in the body is low. Therefore, the feed during this period has become the decisive factor for the future of piglets. The key factor in the development and growth trend, a little carelessness will directly lead to a series of problems such as poor digestive ability and stress resistance ability of piglets, loss of appetite, digestive disorders, diarrhea, low feed utilization rate, easy infection of diseases, low survival rate, etc. , so how to design a scientific and reasonable feed formula for piglets within ten days after weaning is the focus of current research, but the feed formula developed for piglets within 10 days after weaning has not been reported yet, and there is still a big gap
