Description
Technical field
The present invention relates to a kind of animal rumen bypass stable equilibrium fatty powder and preparation method thereof.
Background technology
After milk cow calving, the output of milk increases sharply, but the increase of feed intake lags behind the increase of the output of milk, Power supply can not meet the demand of energy and cause negative energy balance, limit Lactation of Dairy Cow amount, cause ketoacidosis and fatty liver diseases, affect reproductive performance and the Milk Production of milk cow.Fat is as most important, the most effective energy source, and its contained energy is 2.25 times of protein and carbohydrate energy content, adds the energy concentration that fat effectively can improve daily ration in daily ration.At present, in order to increase the absorption of milk cow energy, the method that a lot of milk cattle cultivating person commonly uses adds fat in daily ration, but effect often and pessimistic, even sometimes also can the reproductive performance of serious harm milk cow.
In fact, be degraded by microorganisms as aliphatic acid and glycerine immediately after not protecting fat to arrive cud in daily ration, hydrolysis degree, up to 85 ~ 95%, has obvious inhibitory action to lumen fermentation, significantly can reduce ox to dry and cellulosic digestibility.In addition, in daily ration also can there is hydrogenation in unrighted acid under the effect of rumen microorganism, forms saturated fatty acid, affect fat digestibility.In daily ration, protection fat can slow down the degraded of fat at cud, does not affect lumen fermentation.Current international market mainly contains 3 class ruminally-protected fat products: palmitic acid is main palm oil fatty powder, hydrogenated fat powder and fatty acid calcium salt.Palmitic acid is that main palm oil fatty powder, fatty acid calcium salt and hydrogenated fat powder has multiple brand, but aliphatic acid composition is very similar, forms primarily of palmitic acid and stearic acid, and aliphatic acid composition is single.In addition, fatty acid calcium salt quality is unstable, palatability is poor affects ruminant feed intake, and hydrogenated fat destroys the structure of aliphatic acid, digestive utilization ratio is low, all fully can not meet the demand of ruminant to energy, and do not consider the balanced fatty acid in milk cow lipid nutrition, especially the balance of function aliphatic acid, essential fatty acid, n3 aliphatic acid and requirement.For current fat products, palmitic acid, stearic acid content are too high, Short-Chain Fatty Acids, essential fatty acid and n3 aliphatic acid relative deficiency.And, add fat in dairy cow diet, often cause milk butterfat percnetage to increase, and content of milk protein reduces.
Summary of the invention
The object of the invention is to solve the rumen-protected fat products of existing animal, to there is aliphatic acid composition single; quality is unstable, palatability is poor, digestive utilization ratio is low and can not meet the problem of ruminant to the demand of energy, and provides a kind of ruminant rumen stable equilibrium fatty powder and preparation method thereof.
