Abstract
The invention relates to a pregnant sow constipation prevention feed and a preparation method and application thereof, wherein the pregnant sow constipation prevention feed comprises the following components: base material, composite dietary fiber, composite probiotics, premix and nutritional supplement. The feed is added with the composite dietary fiber and the composite probiotics simultaneously, and the two are used together, so that the constipation of pregnant sows can be remarkably relieved, the labor process is shortened, the postpartum inflammation is reduced, and the postpartum food consumption is improved. Wherein the adding proportion of the composite dietary fiber is not required to be too high, so that the composite dietary fiber fully exerts respective advantages. The composite probiotics can regulate the fermentation of dietary fibers in the intestinal tracts of the sows, influence the generation of acetic acid, propionic acid, butyric acid and lactic acid, promote the intestinal health of the sows and avoid constipation; can also supplement a large amount of physiological bacteria, correct flora change during constipation, and promote digestion, absorption and utilization of food.
Description
Technical Field
The invention belongs to the technical field of feeds, and relates to a constipation prevention feed for pregnant sows and a preparation method and application thereof.
Background
The pig breeding is an important ring in the traditional industry and the modern breeding industry. In the process of the rapid development of modern pig breeding in recent years, antibiotics and chemical drugs are abused by part of farms, so that the intestinal flora balance of animals is seriously disturbed, the intestinal mucosa is thinned, the immunity is reduced, and the whole livestock is in a sub-health state, so that the modern pig breeding industry not only needs large-scale, intensification and modernization, but also needs greening, safety and no resistance. In pig production, an important link determining the production level and the economic benefit is healthy breeding of pregnant and lactating sows, and the constipation problem is the most common and most influential problem of the pregnant and lactating sows, particularly in the middle and later periods of pregnancy, the incidence rate of constipation is about 30-40%, and the incidence rate of constipation in partial farms is even as high as 60-70%. The constipation can lead to the loss of spirit and appetite of pregnant sows, the reduction of feed intake and water intake, the prolongation of the delivery process and even dystocia, the death of fetus of serious patients or the damage of toxin in excrement to organs, the metritis and the mastitis are caused, the lactation is influenced, the diarrhea rate of newborn piglets is high, the healthy piglet rate is low, and the loss of the pig raising production is caused.

The feed has the advantages of considering both the thickness and the fineness, balancing nutrition, promoting the digestion and the absorption of gastrointestinal tracts, preventing the sows from food retention and qi stagnation and abdominal distension and constipation, and also has the function of treating the sows with constipation.
CN1608490 discloses a compound premix for preventing drug-induced constipation of sows, which comprises a compound premix for preventing drug-induced constipation of sows and a compound premix for treating drug-induced constipation of sows, wherein the premix is prepared by uniformly mixing microelements (iron, copper, manganese, zinc, iodine, selenium), vitamins (A, D, E, B1, B2 and the like), amino acid, disease-resistant growth-promoting drugs and carriers according to a certain proportion, the compound premix for preventing drug-induced constipation of sows is prepared by adding aureomycin into the premix for sows, and the dosage of the aureomycin is reduced to 25-30 g per ton of complete feed, so that drug-induced constipation of sows at the later stage of pregnancy and lactation is prevented. The sow drug-induced constipation treatment type composite premixed feed is prepared by adding 10-15% of sodium sulfate into premix components and mixing the mixture to prepare the feed, and is used for treating drug-induced constipation of sows at the late pregnancy and lactation period.
However, various dietary fibers or other drugs for relieving constipation which are commonly used at present have unobvious effects and certain limitations, such as: bran causes abdominal distension, flatulence, poor iron and calcium absorption and the like, has high addition ratio (generally over 10 percent), is easy to mildew and deteriorate, and causes the standard exceeding of mycotoxin to influence the quality of feed. Therefore, research and development of feeds more suitable for relieving constipation of pregnant sows become an urgent practical need for live pig breeding at present.
