Al technical title is built by PatSnap Al team. It summarizes the technical point description of the patent document.
A feed additive, a technology for weaning piglets, applied in the direction of animal feed, animal feed, application, etc., can solve the problems of increased weaning stress syndrome of piglets, gastrointestinal dysfunction of piglets, slowed growth of piglets, etc. The effect of producing, inhibiting the growth of harmful bacteria, and promoting proliferation
This helps you quickly interpret patents by identifying the three key elements:
Problems solved by technology
Method used
Benefits of technology
Problems solved by technology
However, early weaning stress in piglets will cause gastrointestinal dysfunction in piglets, induce early weaning syndrome in piglets, lead to slow growth or stagnation, and even death of piglets. and pig production have had huge negative impacts
Therefore, it is of great significance to study piglet weaning stress and adopt reasonable and effective prevention and control measures to promote the development of pig industry and even animal husbandry, and there is no research on the use of D-ribose additive in weaned piglet feed before this application and related reports

Embodiment 3
[0025] Each 100g feed additive contains: D-ribose 50g, bran 17g, corn cob powder 13g, medical stone: 8g, high calcium stone powder 12g. The above materials are pulverized in a pulverizer, passed through a 60-mesh sieve, and uniformly mixed according to the stated weight to make a feed additive. (2) Application of the feed of the present invention on weaned piglets
[0026] 1. Purpose of the experiment
[0027] To study the effects of D-ribose on growth performance and serum biochemical indexes of weaned piglets.
[0028] 2. Experimental animals and experimental design
[0029] In the experiment, 192 weaned "Du × Chang × Da" piglets at the age of 28 ± 2 days were randomly divided into 4 groups, with 6 repetitions in each group and 8 pigs in each repetition, and were fed with 4 kinds of diets: (1) Basic diet (control group); (2) basic diet+200mgD-ribose additive / kg basic diet; (3) basic diet+300mgD-ribose additive / kg basic diet; (4) basic diet+500mgD - Ribose supplement / kg b...

Abstract
The invention relates to a weaned pig feed containing a D-ribose feed additive. The feed is characterized by further comprising the following main raw material components: corn, bean pulp, fish meal, yeast powder, calcium hydrophosphate, shell powder, soybean oil and salt. Microelement premix and the D-ribose feed additive are further added in the main raw materials. The D-ribose additive comprises D-ribose, bran, corncob powder, medical stone and high-calcium stone powder. The premix comprises vitamin A, vitamin D3, vitamin E, vitamin K3, vitamin B1, vitamin B2, vitamin B6, vitamin B12, niacin 20, d-pantothenic acid, biotin, folic acid, Cu, Fe, Zn, Mn, Co, Se and iodine. By adjusting the main feed recipe and adding the D-ribose feed additive and the premix microelement in the main feed, the microbial flora balance in an animal body is improved, and the proliferative activity of intestinal bifidobacterium is promoted selectively, so that the daily gain and the propagation performance of weaned pigs are improved.
Description
technical field [0001] The invention relates to the technical field of weaned piglet feed, in particular to a weaned piglet feed containing D-ribose feed additive. Background technique [0002] The wide application of antibiotics has made great contributions to the development of animal husbandry. Feed antibiotics can inhibit the growth and reproduction of harmful microorganisms in the digestive tract of livestock and poultry, reduce the consumption of nutrients in the body, and promote the synthesis of essential nutrients for animals in the digestive tract. The reproduction of beneficial flora increases the synthesis of nutrients, inhibits or kills some pathogenic microorganisms, enhances the disease resistance of livestock and poultry, prevents diseases, and thins the intestinal wall, thereby facilitating the penetration and absorption of nutrients and increasing appetite. . However, while the application of antibiotics has brought great benefits to people, its abuse has ...
