Abstract
The invention discloses feed active egg powder with nutrition, healthcare and growth promotion functions and a production method thereof, wherein the feed active egg powder with nutrition, healthcare and growth promotion functions is obtained by fully mixing weighed enterotoxin-resistant Escherichia coli tetravalent yolk antibody, C-type clostridium perfringens and beta toxoid-resistant divalent yolk antibody, rotavirus-resistant yolk antibody, transmissible gastroenteritis and epidemic diarrhea-resistant bigeminal yolk antibody, cholecystokinin/somatostatin-resistant double-fusion white and yolk antibody, lysozyme meringue powder, epidermal growth factor-containing meringue powder, common meringue powder and silica (antitackiness agent) for 60 to 100 seconds. The feed active egg powder with nutrition, healthcare and growth promotion functions provided by the invention has the beneficial effects of containing high-quality protein, fat and amino acid required for the growth and development of piglets, containing lysozyme, yolk antibody and epidermal growth factor for preventing disease, protecting health and promoting growth, and having four efficacies of enhancing the feed intake, accelerating the growth, boosting the immunity and controlling the diarrhea of the piglets before and after weaning.
Description
Technical field
The present invention relates to animal feed and biomedicine field, be specially a kind of active powdered egg of feed and production method thereof with nourishing healthy growth promotion function.
Background technology
The sucking pig early weaning not only can be brought into play sow production capacity to greatest extent, improves and produces parity per year, and can reduce transmission of disease between female son.Yet, behind the early weaning piglet, can be subjected to various unfavorable factors stress with the invasion and attack of cause of disease, it is grown and survive has produced bigger influence, situation such as occur searching for food that declines, diarrhoea are lost flesh, hair color dries up, growth retardation, survival rate are low is commonly called as " weaning syndrome ".Main cause has: 1. behind the weaned piglet, losing its passive immunity protection of breast milk has reduced, and the active immunity system of body does not set up as yet fully, is subjected to the invasion and attack of various cause of diseases such as Escherichia coli, C.perfringens, rotavirus, transmissible gastroenteritis of swine and epidemic diarrhea easily and falls ill; 2. weanling pig has lost somatotrophic some active material of newborn source property, causes the marked change of small intestinal mucosa structure and function, is affected thereby cause body growth to be grown, and disease takes place easily, even dead; 3. feed intake reduces, and digests and assimilates ability drop, subalimentation, growth retardation; 4. the influence of ANFs such as soybean antigen albumen etc. in the feedstuff; 5. ablactation stress can cause the hormonal change of piglet, and some antigrowth hormone secretion amounts increase, from maincenter level affects growth in piglets.
Current, the method that solves a weanling pig difficult problem in the production has: 1. add, use a large amount of antibiotic or chemicals in feed and feeding process, though bacteria resistance diarrhoea is effective like this, but it is invalid to virus diarrhea, and medicament residue is serious, does not meet the food security and the healthy aquaculture development trend of people's growing interest.And use antibiotic can produce drug resistance for a long time, make antibiotic become invalid on the one hand, cause antibiotic abuse on the other hand, the serious harm human health; 2. add 2500PPM zinc oxide in piglet creep feed, the control grice diarrhoea is had certain effect, but influence the hair color of piglet, a large amount of zinc oxide pollute environment.3. use SDPP in the piglet creep feed: SDPP is with slaughterhouse's pig blood, through centrifugation serum and blood cell gained serum, the serum spray-drying is formed again.Contain protein 78%, immunoglobulin (Ig) 10%, and protein digestibility utilization rate height also contain a small amount of somatomedin.Having increases the effect of searching for food, promoting to grow, reduce diarrhoea, generally uses on producing.But, there is bio-safety hidden danger because homology and production procedure do not have process for sterilizing.Owing to differ in pig blood source, the SDPP quality is difficult to stable simultaneously.
Therefore, how to improve the searching for food of weanling pig, digest, absorption and conversion capability, improve the immunity of weanling pig, control diarrhoea property disease takes place, make the weanling pig fast speed cross the child care vulnerable period, reduce or cancel the use of antibiotic medicine, realize the healthy ecology breed, proposed the series of studies problem for feed nutrition and animal medicine circle.
Summary of the invention
Technical problem solved by the invention is to provide a kind of have active powdered egg of the somatotrophic feed of nourishing healthy and production method thereof, to solve the problem in the background technology:
The invention provides the active powdered egg of the somatotrophic feed of a kind of nourishing healthy, the active powdered egg of this feed comprises anti-grice diarrhoea yolk antibody, growth promotion yolk antibody, egg white lysozyme and EGF.Wherein: anti-grice diarrhoea yolk antibody comprises anti-enterotoxin type Escherichia coli tetravalence yolk antibody, anti-C type C.perfringens and β toxoid bivalent antibody, anti-rotavirus yolk antibody, anti-swine infectious enterogastritis/epidemic diarrhea bigeminy yolk antibody, has piglet red dysentery, yellowish-white dysentery, wean back diarrhoea and the transmissible gastroenteritis that control enterotoxin type Escherichia coli, C.perfringens, rotavirus, transmissible gastroenteritis of swine, pig epidemic diarrhea cause, the generation of epidemic diarrhea disease; The growth promotion yolk antibody is the two fusion yolk antibodies of anti-CCK/growth hormone release inhibiting hormone, CCK and growth hormone release inhibiting hormone in the energy and in the body, weaken CCK and growth hormone release inhibiting hormone to search for food, the inhibitory action of gastric acid secretion, digestive ferment and growth hormone, increase the feed intake of piglet, strengthen digestive function, improve the speed of growth; Egg white lysozyme is that a kind of in clear has sterilizing function protein from egg, and is active high, has anti-inflammation, antiviral, the effect that strengthens immunity; EGF can promote the chorial growth of enteron aisle, improves the activity of brush border digestive ferment, improves digesting and assimilating of nutriment, promotes piglet growth.
