Abstract
The invention discloses a feed for sows in a lactation period and a preparation method thereof. The modified zeolite powder and the coarse feed are fermented together, and then mixed forage powder, mixed protein powder, compound vitamin and water are added, and the mixture is evenly mixed and granulated to obtain the feed. The feed for the lactating sows, prepared by the method, is good in palatability, provides balanced nutrition for the lactating sows, can adsorb toxin and heavy metals, avoids intestinal absorption, is discharged out of bodies along with excrement, supplements microelements such as selenium and calcium for the lactating sows, prevents postpartum lactation heat of the sows, improves intestinal health, increases feed intake, and improves lactation yield and lactation capacity.
Description
Technical Field
The invention belongs to the technical field of animal feed preparation, and particularly relates to a feed for sows in a lactation period and a preparation method thereof.
Background
A lactating sow is generally a sow which is post-parturition of a pregnant sow and is in lactation. The levels of energy, protein, lysine and other nutrients required by a lactating sow are determined by the sow's own body weight, milk production and feeding environment.
The high and low lactation yield of the whole-period lactating sows determines the good and bad production performance of the lactating piglets, and the lactation yield of the lactating sows is obviously reduced in summer, so that a series of problems of increased death rate of the piglets in the lactation period, reduced weight of the weaned piglets, increased diarrhea rate of the weaned piglets, reduced activity of the weaned piglets and the like are caused. At present, additives such as sweetening agents, flavoring agents or gamma-aminobutyric acid are added into the feed of nursing sows to improve the feed intake of the sows, so that the lactation yield is improved. Compared with other seasons, the effect of improving the feed intake by simply adding the phagostimulants in summer is not ideal, and the heat stress problem of the sows cannot be effectively solved, so that the problem of insufficient lactation is difficult to thoroughly solve.
The invention Chinese patent CN 107319163B discloses a lactating sow compound feed and a preparation and use method thereof, aiming at the problems that the prior lactating sow has low lactation yield in summer and can not meet the normal demand of piglets, the invention provides the lactating sow compound feed which comprises the following raw materials: each ton of feed comprises 700kg of corn-. The feed disclosed by the invention is reasonable in formula and high in nutrition level, can effectively improve the summer feed intake of lactating sows, enhances the digestion and absorption capacity and the heat stress resistance of the sows, improves the lactation performance of the sows by more than 20% compared with the lactation performance of the sows fed with other feeds, and has important economic benefits. However, the nutrient components added in the invention have poor absorption effect on the sows, and the nutrition is seriously lost in the sows.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a sow feed in a lactation period and a preparation method thereof.
The preparation method of the feed for sows in the lactation period comprises the following steps:
(1) uniformly mixing 40-60 parts of mixed fermentation product, 20-40 parts of mixed forage powder, 5-15 parts of mixed protein powder, 1-3 parts of composite vitamin and 15-25 parts of water in parts by weight to obtain mixed feed;
(2) and (2) placing the mixed feed obtained in the step (1) into a feed granulator for granulation to obtain the feed for the sows in the lactation period, wherein the particle size is 0.5-1.5 cm.
The preparation method of the mixed fermentation product comprises the following steps:
s1: uniformly mixing 30-50 parts of corn flour, 30-50 parts of sorghum flour, 15-25 parts of wheat bran, 10-20 parts of bean curd residue and 30-50 parts of water in parts by weight to obtain a coarse mixture;
s2: uniformly mixing 8-20 parts by weight of modified zeolite powder, 0.4-0.6 part by weight of bacillus subtilis and 80-120 parts by weight of the crude mixture obtained in the step S1 to obtain a fermentation substrate;
s3: and (4) placing the fermentation substrate obtained in the step (S2) into a fermentation tank, and sealing and fermenting for 30-40 hours at 23-27 ℃ to obtain a mixed fermentation product.
The preparation method of the modified zeolite powder comprises the following steps:
t1: putting the zeolite powder into a tubular furnace, heating to 400-420 ℃ at the initial temperature of 20-30 ℃ at the heating rate of 4-6 ℃/min, keeping for 1-3 hours, then cooling to 70-90 ℃ at the cooling rate of 8-12 ℃/min, transferring to 4-6 ℃ and keeping for 20-40 minutes to obtain physically modified zeolite powder;
t2: adding 15-25 parts by weight of the physically modified zeolite powder obtained in the step T1 into 40-60 parts by weight of the modification solution, uniformly mixing, soaking at 50-70 ℃ for 2-4 hours, and filtering to obtain a filter cake to obtain a mixture A;
