Embodiment 1

[0027] Embodiment 1: a kind of bio-fermented feed for lactating sows mainly comprises the following steps:

[0028] (1) Take 24 parts of corn, 30 parts of bran, and 6 parts of sugar beet meal and mix them with a pulverizer (Yangzhou Kerunde, the same below). After pulverizing (No. 20 sieve), pass 50% of the material through 60 mesh The sieve shall prevail; the role of raw material crushing: to improve the pretreatment effect of raw materials and the quality of finished products.

[0029] (2) 60 parts of the mixed material obtained after crushing in the step (1), compound enzyme (1.2 parts of protease at 10000U / g, 1.2 parts of Aspergillus at 5000U / g and 1 part of phytase at 8000U / g Composition) 2 parts, culture medium (brown sugar) 3 parts and mix well.

[0030] (3) Add 3 parts of 30°C inoculum solution, 2 parts of molasses, and 30 parts of 50°C hot water to the materials in the step (2) and mix thoroughly. The strain liquid consists of freeze-dried lactic acid bacteria agent...

Embodiment 2

[0033] Embodiment 2: a kind of biological fermented feed for lactating sows mainly comprises the following steps:

[0034] (1) First take 26 parts of corn, 32.5 parts of bran, and 6.5 parts of beet meal, mix them with a pulverizer (Yangzhou Kerunde, the same below), and after pulverization (No. 20 sieve), pass 50% of the material through 60 mesh The sieve shall prevail; the role of raw material crushing: to improve the pretreatment effect of raw materials and the quality of finished products.

[0035] (2) 65 parts of the mixed material obtained after crushing in the step (1), compound enzyme (1 part of 12000U / g protease, 1 part of U / g Aspergillus and 1 part of 9000U / g phytase Composition) 2.5 parts, culture medium 2.5 parts are fully mixed.

[0036] (3) Add 2 parts of 30°C strain solution, 2 parts of molasses, and 26 parts of 50°C water to the material in step (2) and mix thoroughly. The strain liquid consists of freeze-dried lactic acid bacteria agent (containing live lacti...

Abstract

The invention discloses biological fermentation feed for lactating sows, and a preparation method of the biological fermentation feed, and aims to solve the technical problems of low feed intake of the lactating sows and low weaning litter weight of piglets in the prior art. The fermentation feed is mainly prepared by mixed fermentation of a fermentation substrate, a compound enzyme, a culture medium, a strain solution, molasses and the like. By reasonable setting of a raw material fermentation technology, the physical structure and the chemical characteristics of each main raw material are changed, so that the nutritional value of the feed raw materials is improved, the utilization rate of the feed by lactating sows can be improved, and the parturition performance of the sows is comprehensively improved. The raw materials are in synergetic cooperation, so that the feed intake of the lactating sows can be remarkably increased, and the weaning litter weight of the piglets is increased.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a biologically fermented feed for lactating sows and a preparation method thereof. Background technique [0002] When piglets are weaned at 21 days, more than 90% of the nutrition for their weight gain comes from breast milk, so the nutrition provided by lactating sows has a great impact on the growth of piglets. Breast milk is transformed from feed nutrition. If the nutrition in feed cannot meet the needs of piglets for milk, on the one hand, the weaning weight of piglets will drop, and on the other hand, sows must use their own body tissues to convert milk to meet the needs of piglets. Growing need for milk. [0003] If a lactating sow does not eat enough energy, the sow will consume its own backfat to turn it into energy for breast milk, and if the intake of protein and amino acids is insufficient, the sow will use muscle tissue to convert it into protein in breast milk. If the...
