After the birth of lamb, calf, survive by provide nutrition to carry out the transition to by maternal blood by parent milk, physique a little less than, resistance to external world is lower, the digestive system of body itself is not sound as yet, and the speed of growth is very fast simultaneously, needs nutritious and digestible nutriment.Breast milk is best food, yet, because multiple birth, the polyembryony son that dam physique is weak, dam primiparity, particularly embryo transfer parent are produced, often in the breast milk deficiency that just seems within these few days in postpartum, and lamb, calf critical period of growing just this moment, if the nutriment undersupply will influence its all one's life, severe patient death brings very big loss for the enlarged reproduction of production and population.
The batch production of mutton sheep and beef cattle, intensification are produced and are objectively required dam to breed fast, lamb and calf early weaning and growth and fattening fast, and therefore producing milk replacer seems particularly important, this point has obtained the extensive attention of countries in the world.
Breast milk is optimal food for newborn lamb and calf.Colostrum and normal breast can satisfy the nutritional need of new born animal, make lamb and calf improve the immune system of itself early simultaneously, can match with lamb aspect the sense of taste and the body fluid type again.In production practices, breast milk can be affected because of health and the disease of dam, the more important thing is that the breast milk quantity not sufficient has influenced the g and D of lamb and calf.
The problem that the milk replacer demand side is right
The needs of nutrient
Milk replacer will replace breast milk feed lamb and calf and reach production performance preferably, objectively require milk replacer on nutritional labeling and immune component near breast milk, simultaneously lamb and calf can be accepted.According to Jandal (1996), Goat Milk, ewe's milk and milk respectively have characteristics on constituting, be higher than Goat Milk and milk on the fat of ewe's milk, protein and the casein content; The liposoluble vitamin of Goat Milk and Vit C contents are apparently higher than ewe's milk and milk; The calcium and the phosphorus content of three kinds of milk are near each other.Analyze milk not as goat milk from nutritional labeling, existing report, its production performance of lamb of feeding early weaning with milk is undesirable, because the milk of the same amount of lamb feed can not satisfy its demand to nutriment and other unknown factor.This milk replacer that objectively requires to be used for goat lamb, sheep lamb and calf is not quite similar.How foreign enterprises produces special-purpose milk replacer is targetedly used for different cubs, to reach best productivity effect.
The raw material of milk replacer is selected
The selection of milk replacer raw material is a key issue, and the user uses the economic interests of milk replacer to be to save cost, and too high will being difficult to of milk replacer cost accepted by the user.The milk replacer raw material that uses mainly contains (Sanz etc., 1997) such as full-fat cow milk, whey powder, whole soya-bean powder, SDPP, FSPC, vitamin and microelement extenders at present.For reducing the production cost of milk replacer, milk replacer is many to be primary raw material with the bean product.Bean product mainly contains three kinds of products, soy meal, soybean protein essence and soy protein isolate.The former cost is minimum, but contains cellulose and insoluble carbohydrate, and the protein content of soy protein isolate is up to 85%~90%, but cost is higher.The unfavorable factor of the milk replacer made from soybean protein source is, contains trypsin ihhibitor and anaphylactogen in the milk replacer, and these two kinds of factors all can cause the reduction of nutritional labeling digestibility and the weakening of production performance.Trypsin ihhibitor has the advantages that to reduce digestive enzyme activity, soybean is carried out humid heat treatment can destroy their inhibitory action.Glycinin and β-haptoglobin are the main existing waies of protein in the soybean, and they have sensitization to lamb.Yao Lukun etc. (2000) report, soy meal is handled with spontaneous fermentation acidifying heating means, the sheep lamb that in milk replacer, replaces powdered milk feed 12~17 ages in days with 60% ratio, the lamb feed intake does not have obvious reduction, to handling soy meal digestibility is preferably arranged, but production performance is lower than the lamb of the milk powder of feeding.
Lower and the easy digestion of whey powder cost is the raw material commonly used of milk replacer, yet whey powder is higher owing to lactose content, and protein and fat content are low, excessive lamb and the calf diarrhea (Havrevoll etc., 1991) of easily causing of consumption.
Protein in the milk replacer and energy
Lamb powered milk substitute requires for the enough energy of lamb, Sanz etc. (1997) suggestion, and the energy in the powered milk substitute: protein rate should be higher than the goat milk of nature, only in this way just can help the absorption of protein; Usually the protein content in the milk replacer should be more than 30%, and contains sufficient essential amino acid, because lamb is before the rumen microorganism system perfecting, lamb is very close to the needs and the nonruminant of nutriment.The fat content that increases in the powered milk substitute is to improve energy level, and the common energy of supplying with is that lamb is kept 1.5~2.5 times that need.According to Fuente (1998), fat level is more than 25% in the milk replacer dry, and behind the thin up, for dry matter content in the emulsion 16.6%, thick protein is 3.9%, crude fat 3.8%, ash 12.5%, calcium 1.7%, phosphorus 1.2%.How adding fat and be technological problems is again nutritional need, and comparatively desirable method has two, one at present, and fat and other milk replacer composition are carried out the homogeneous processing, and fat fortification is added milk replacer; The 2nd, fat is carried out vacuum diffusion or spray-drying adding milk replacer.Sanze etc. (1997) have adopted in test another kind of method, he adds lard in milk replacer, at first lard is dissolved, join in the milk replacer then and stir simultaneously, adding lard needs to add synchronously emulsifying agent, as Tween 80, helps the emulsification and the homogeneous of milk replacer like this, the result shows, adds the purpose that lard can reach equally increases fat or energy in milk replacer.
The making that correct selection raw material is a milk replacer is laid a good foundation, but milk replacer has its requirement, and promptly milk replacer must keep the emulsified state of homogeneous after brewing with the burning boiled water, and caking and precipitation can not be arranged, otherwise will influence the use and the effect of milk replacer.
The purpose of this invention is to provide a kind of powered milk substitute that satisfies lamb, calf full nutrition needs and have immune active ingredient, this product can promote growth and the growth of lamb and calf, accelerates the reproductive efficiency of dam, and the raw material convenient sources, nutrition is stable, and cost is lower.
The nutriment that contains calf, lamb needs in the product of the present invention: protein, fat, lactose, amino acid, vitamin, mineral matter element, also contain cud simultaneously and promote and the rumen microorganism conditioning agent.
