Sucking pig child care mixed feed in early stage and preparation method thereof
Technical field
The mixed feed of feeding when the present invention relates to the sucking pig wean, particularly a kind of sucking pig child care mixed feed in early stage and preparation method thereof.
Background technology
In recent years, along with pig is cultured the development of industry, to sucking pig child care material require increasingly highly because in Swine Production, raising sucking pig scientifically and rationally is one of the key link of success of raising pigs.It not only influences the growth in this stage, also has a strong impact on later production performance, and the sucking pig wean then is the key factor during sucking pig produces.In traditional Swine Production, be everlasting 45~60 ages in days wean of sucking pig.For improving the year productivity of sow, often through the early weaning technology, the age in days that will wean shortens to 21-28 ages in days in the modern Swine Production process; To shorten the lactation of sow; In addition, female young early stage separation can prevent that sow from killing sucking pig and reducing the chance that sucking pig infects infectious disease and parasitic disease, helps improving the sucking pig survival rate; Can improve simultaneously hurdle house utilization rate, however early weaning also will cause sucking pig to produce stress.Stress be meant that body to external world or the inner various summations that stimulate very much the nonspecific response reaction that is produced.During the sucking pig early weaning, because the influence of stressors such as environment, nutrition, often show as that appetite is poor, the disorders of digestion, diarrhoea, growthing lag, efficiency of feed utilization is low etc., so-called sucking pig early weaning syndrome that Here it is.Its priming factors mainly is that nutrition stress.Lactation sucking pig before the wean, its nutrition is all or part of to be provided by breast milk, contains abundant fat and the casein that is easy to digest in the pig breast milk, and its carbohydrate is to be main with lactose, not starch-containing and fiber.And after the wean, the butterfat of main energy source is substituted by cereal starch, and the wine albumen that can be digested and assimilated has fully become the lower vegetable protein of digestibility, and the fiber that also has sucking pig almost can not digest in the feed.Therefore, sucking pig digestive enzyme system and physiological environment etc. are all incompatible.It is weightless to cause sucking pig to occur; Blood sugar, insulin and level of growth hormone, hepatic glycogen, gastric content weight average reduce; Stomach pH value, free fatty acid levels raise, and its result shows and is wean sucking pig feed intake and efficiency of feed utilization reduction, indigestion and the generation that causes diarrhea clinically.General sucking pig searches for food in wean (3-4 age in week) first and second sky, back hardly, and along with time ground prolongs, the sucking pig body weight descends, and body fat consumes, and hunger just makes sucking pig slowly begin to search for food.In a week after the general wean, sucking pig only searches for food about 1.5 kilograms, and the body weight increase seldom or does not almost increase; Therefore the daily ration that offers the early weaning sucking pig must very easily digest; And the intestines wall do not produced antigenic action, if the nutrition that causes because of wean stress be overcome, so; Converting solid feed into from the pig breast also will have wound seldom, and the growth of sucking pig possibly increase.Because of the back feed intake increase of weaning possibly have potential spread effect with function to the mucous membrane growth, this has the integrality that helps to keep small intestine and promotes to grow through strengthening or keep the ability of digesting and assimilating.For this reason, can guarantee sucking pig early weaning successfully can relax again therefore overcome and to sucking pig cause strongly stress, be the problem that the science of raising pigs the present age and animal nutrition are paid close attention to.
