Description
Technical Field
The invention relates to a feeding method of IUGR weaned piglets, belonging to the technical field of pig breeding methods.
Background
Intrauterine growth retardation (IUGR) is a general term for the disturbance of the development of a fetus in the mother uterus, refers to a phenomenon that the growth and development of the embryo or organ of a mammal in the uterus are damaged and do not reach the normal growth potential, and is a main reason for the remarkable difference of the birth weight of the littermate. There are many causes for the intrauterine growth retardation of piglets, including maternal, placental and fetal factors, such as inadequate maternal nutrient intake during pregnancy, disease, environmental stress and maternal uterine and placental dysfunction, among others, while sow nutritional deficiency during pregnancy is the most prominent cause. The ovulation number of the sow is 20-30, the conception rate reaches 90%, the average number of embryos is 10, and the embryos are planted in the uterus and developed to form mature fetuses. When the number of fetuses exceeds the bearing capacity of the piglets, the number of muscle fibers of the piglets is relatively reduced, nutrient substances and oxygen supply are limited, the fetuses are supplied from mothers, the shortage of maternal nutrition can reduce the obtainment of oxidizable substrates and macromolecular synthetic precursors of the fetuses, the growth and development ability of the fetuses in the uterus is reduced, in addition, the insufficient blood supply of the fetuses and the placentas is easily caused, the flowing of the nutrient substances into the fetuses is influenced, and the growth and development delay of the fetuses in the uterus of the sows are caused.
Because intrauterine growth retardation can obviously influence the survival rate, growth performance and health condition of offspring individuals, IUGR piglets are small in size, lack in digestive function and immune function and poor in vitality, the survival rate is very low under the general production level, the morbidity and growth rate of piglets in the lactation period are obviously lower than those of normal piglets, and huge loss is caused to livestock production and human health.
For example, Chinese patent application with application publication number CN105146179A discloses a pregnant sow feed for improving the intrauterine growth retardation of a fetus, the pH value of the gastrointestinal tract of a piglet is adjusted by adding an acidifying agent, the digestive enzyme activity is improved, the digestion and absorption of nutrient substances are promoted, the digestion capacity and the utilization rate of the feed are improved by an enzyme preparation, the microecological balance of intestinal tracts is maintained by composite probiotics, constipation is prevented, the placenta angiogenesis and dilatation are promoted by arginine, the insufficient function of the placenta of uterus is improved, the birth weight and the birth weight of a newborn piglet are improved by β -hydroxy- β -methylbutyric acid, the incidence rate of the IUGR piglet is reduced, and the skeletal muscle development of the piglet is improved.
However, no feeding method for IUGR weaned piglets exists at present, and the technical problem of how to improve the survival rate of piglets by late-stage feeding still needs to be solved.

The basic ration has high digestibility and high tensile strength.
Preferably, the fermentatively inoculated fermentation bacteria include pediococcus pentosaceus, lactobacillus plantarum, bacillus subtilis, and saccharomyces cerevisiae. The pediococcus pentosaceus and lactobacillus plantarum in the zymocyte are leavening agents; the bacillus subtilis and the saccharomyces cerevisiae are used as auxiliary agents, consume oxygen in early stage, generate protease and growth factors, and promote the growth of lactic acid bacteria and the generation of lactic acid.
Preferably, the mass ratio of the milk powder to the sugar in the fermentation raw materials is 12-16: 4-5.5. Controlling the ratio of milk powder to sugar within the above range can provide a suitable carbon-nitrogen ratio for the fermentation process, thereby facilitating the optimal growth of bacteria and the production of products.
In order to further improve the daily weight gain and reduce the feed-weight ratio of IUGR weaned piglets, preferably, the fermented milk is prepared by inoculating fermentation bacteria into a fermentation substrate mainly comprising milk powder, glucose and water for fermentation, and the inoculation amount of the fermentation bacteria is controlled in such a way that the viable count of Pediococcus pentosaceus in the inoculated fermentation substrate is (4.0-5.5) × 107CFU/L, viable count of Lactobacillus plantarum (1.8-3.0) × 107CFU/L, the viable count of the bacillus subtilis is (2.9-3.5) × 106CFU/L, the viable count of the saccharomyces cerevisiae is (0.9-1.6) × 107CFU/L; the mass ratio of the milk powder to the glucose to the water in the fermentation substrate is 12-16: 4-5.5: 70-80.
Preferably, the fermentation is stopped when the raw materials are fermented at the temperature of 28-32 ℃ until the pH value is 5-6. If the pH value is low when fermentation is stopped, the fermented milk has pungent smell and diarrhea occurs after feeding.
Preferably, the breeding method of the IUGR weaned piglet further comprises the step of feeding the basic ration after mixed feeding, wherein the feeding time of the basic ration is not less than 14 days. By feeding basal ration after mixed feeding, the adverse effect of weaning stress on IUGR growth performance can be weakened.
