Embodiment 1

[0009] Embodiment 1: Using the mixed auxiliary material of the present invention, 100 kg of digestible amino acid low-protein diets for piglets (10-25 kg) were prepared. The formula of compound feed is: 71kg of energy feed (corn), 25kg of mixed auxiliary material of the present invention, and 4kg of premix. The formula ratio of the mixed auxiliary material of the present invention is: 33.5% of soybean meal, 20% of fish meal, 16% of corn gluten powder, 20% of whey powder, 1.1% of lysine, 0.2% of threonine, 0.3% of tryptophan, milk Pig compound enzyme 0.4%, fat 8.5%. In the prepared digestible amino acid low-protein feed, the protein content is 15.8%.

[0010] The preparation process is as follows: the soybean meal is firstly crushed, and then part of the crushed soybean meal is taken and premixed step by step with lysine, threonine, tryptophan and suckling pig compound enzyme for standby. Then add other crushed soybean meal powder, fish meal, whey powder, and corn gluten powd...

Embodiment 2

[0013] Embodiment 2: Using the auxiliary material of the present invention, 1000 kg of digestible amino acid low-protein diets for growing pigs (25-60 kg) were prepared. The compound feed formula is: energy feed 820kg (corn 690kg, bran 130kg), auxiliary material 140kg of the present invention, premix 40kg. The formula ratio of the mixed auxiliary material of the present invention is: 35.7% of soybean meal, 53.6% of rapeseed meal, 1.29% of lysine, 0.7% of threonine, 0.71% of compound enzyme for pigs, and 8% of oil. In the prepared digestible amino acid low-protein feed, the protein content is 12.5%. The preparation process of the mixing auxiliary material of the present invention is the same as that of Example 1.

[0014] The formula of 1000kg high crude protein diet at the same stage is: energy feed 740kg (corn 640kg, bran 100kg), protein feed (soybean meal) 220kg, premix 40kg. The total protein content is 16.1%.

[0015] Comparing the two, under the same feeding effect, th...

Embodiment 3

[0016] Embodiment 3: adopt auxiliary material of the present invention, prepare high-yielding laying hen stage digestible amino acid low-protein diet 100kg, the formula of compound feed is: energy feed 72kg (corn 64kg, bran 8kg), the present invention's mixed auxiliary material 18kg, stone powder 7kg, premix 3kg. The formula of the mixed auxiliary material of the present invention is: 15.67% of soybean meal, 27.78% of cottonseed meal, 33.33% of rapeseed meal, 19.72% of meat and bone meal, 2.39% of lysine, 0.28% of methionine, and 0.83% of compound enzyme for poultry. In the prepared digestible amino acid low-protein feed, the protein content is 13.5%. See Example 1 for the preparation process.

[0017] The formula of 100kg high crude protein diet at the same stage is: energy feed (corn) 66kg, protein feed (soybean meal) 23kg, stone powder 8kg, premix 3kg. The total protein content is 15.3%.

[0018] By comparison, it can be seen that under the premise of the same stage and ...

Abstract

The invention provides a mixed auxiliary material for preparing a low-protein feed capable of digesting amino acids, which is applicable to premix self-made feed for small and medium-sized farms. The mixed auxiliary material accounts for 13-35% of the low-protein feed capable of digesting amino acids, and is prepared from 15-70% of conventional protein feed, 26-81% of non-conventional feed, 0.7-3% of essential amino acid and 0.4-1% of enzymic preparations. In the preparation process, vegetable oil and fat and adipose which account for less than 15% of the total quantity of the mixed auxiliary material and calcium hydrophosphate which accounts for less than 5% of the total quantity of the mixed auxiliary material can be added according to needs. Under the precondition of keeping equivalent nutrients with a high-crude-protein daily ration, the protein content of 1-4% in the feed is reduced. By using the invention, soybean meals can be saved, and waste of the amino acid, feed cost and environment pollution also can be reduced. The low-protein feed capable of digesting amino acids can be conveniently prepared by using the auxiliary material disclosed by the invention; and thereby the auxiliary material is suitable for being applied and popularized in domestic small and medium-sized farms.

Description

technical field [0001] The invention relates to animal breeding feed, in particular to auxiliary ingredients for self-prepared feed using premixed materials in small and medium scale farms. Background technique [0002] At present, the production of pigs and poultry eggs in a large number of small and medium-scale farms in my country adopts the traditional high crude protein diet based on total amino acids, and its formula is energy feed (corn, bran) + protein feed (soybean meal) + Premix. The usual practice of a large number of small and medium-scale farms in my country's livestock and poultry monogastric animal breeding industry is to purchase industrial premixed feed, and then prepare other raw materials, and prepare high crude protein feed by themselves according to the formula recommended by the commercially available premixed feed. The level of amino acid is usually calculated according to the chemical analysis value of amino acid in the table of feed raw materials use...
