Can the feed additive calcium formate really regulate the intestinal flora of piglets?
With the increasing concentration of pig breeding, it is more difficult to raise pigs and piglets, and the breeding hardware and software environment need to keep up. Piglet intestinal health problems not only cause piglet diarrhea, but also affect the digestion and absorption of nutrients in the feed, and ultimately affect the growth performance of pigs. Can the feed additive calcium formate really regulate the intestinal flora of piglets?
Piglet intestinal health is manifested in the following aspects:
1. The intestinal structure is well developed and the intestinal villi are intact.
2. The number of beneficial microbial flora in the intestine is absolutely dominant.
3. The immune function of the intestinal mucosa is perfect.
It can be said that intestinal health directly affects the efficiency of piglet breeding. Lead to incomplete development of the piglet's intestines, which affects the efficiency of pig farm breeding. According to statistics, the direct economic loss caused by piglet intestinal problems is as high as 10 billion yuan every year.
Digestive enzymes and activities of feed grade calcium formate
There is only rennet in the stomach of newborn piglets, but very little saliva and pepsin, which are about one-third and one-fourth of those in adults. At the same time, the fundus glands are underdeveloped and cannot produce hydrochloric acid. Due to the lack of free hydrochloric acid, pepsin cannot be absorbed, and protein digestion is almost zero. At this time, only the intestinal glands and pancreas are fully developed, and the activities of trypsin, intestinal amylase and lactase are relatively high. Food is mainly digested and absorbed in the small intestine, so newborn piglets cannot digest plant-based nutrients. The activity of digestive enzymes in the gastrointestinal tract of piglets increases with the age of the week. When the piglets are 0-4 weeks of age, the activity increases exponentially every week.
Piglets are colonized with bifidobacteria and E. coli in the jejunum, ileum, cecum and rectum within 24 hours of birth. During the lactation period of piglets, the microbes in the stomach are mainly lactobacilli. Inherent intestinal flora of piglets is an indispensable and important factor for its growth, development, nutrition and anti-infection, and it has an inhibitory effect on growth.
The role of feed-grade calcium formate in regulating the microflora of the gastrointestinal tract is mainly achieved by lowering the PH value of the gastrointestinal tract. Escherichia coli and enterococci grow well at 6-7 and 7-8 in the digestive tract, and are basically inactivated at pH 4, while lactic acid bacteria still grow well at pH 3.5. The proliferation of lactic acid bacteria further reduces the PH value of the gastrointestinal tract, thereby further inhibiting the growth of harmful bacteria and promoting the digestion of diets. As a feed acidifier, calcium formate itself also has a strong bactericidal effect.
In the past, breeding mainly used antibiotics to prevent and control piglet diarrhea, but green additives that can effectively replace antibiotics after the implementation of "anti-antibiotics" have become an urgent need for the animal husbandry to develop in the direction of green and safety. Therefore, feed grade calcium formate is a green feed additive that can effectively promote the intestinal health of piglets, which is of great significance for improving breeding efficiency and protecting the environment.
