Embodiment 1

[0025] A processing method of green grass feed for young pigs, comprising the following steps:

[0026] (1) Main feed preparation: dry distiller's grains, then crush distiller's grains and soybean meal into powder; then, mix processed distiller's grains, soybean meal, corn flour and salt to prepare main feed;

[0027] (2) Greening the green grass: After the green grass is washed with water, add it to the high-pressure steamer to finish it;

[0028] (3) Microwave drying: the green grass after greening is placed in a microwave dryer for microwave drying treatment: the first stage of rough drying, the drying temperature is 85°C, the humidity is 42%, and the time is 1h; the second stage of fine drying Drying, the drying temperature is 51°C, the humidity is 15%, and the time is 3h. The humidity reduction rate is 5% every 5min until it reaches 15% humidity;

[0029] (4) Grass pulverization: After drying, the grass is pulverized by a pulverizer to make grass dry powder. The pulveriz...

Embodiment 2

[0044] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:

[0045] The main feed described in the step (1), the mass portion of each prepared ingredient is:

[0046] 66 parts of corn flour, 33 parts of liquor distiller's grains, 14 parts of soybean meal, 3.5 parts of iodized salt.

[0047] For the finishing described in step (2), its finishing process parameters are:

[0048] The pressure of the high-pressure steamer is 1.8Pa, the steam temperature is 98°C, and the greening is done for 13 minutes.

[0049] Microwave drying in step (3), the drying process is:

[0050] The first stage of rough drying, the drying temperature is 86°C, the humidity is 44%, and the time is 2h; the second stage is fine drying, the drying temperature is 52°C, the humidity is 16%, and the time is 4h, in which the humidity decreases by 5% every 5min , until a humidity of 16% is reached.

[0051] The fermented liquid described in step (5), its each preparatio...

Abstract

The invention discloses a processing method of piglet green grass feed. The method is characterized by comprising the following steps of (1) major feed preparation: baijiu vinasse, bean pulp, corn starch and table salt are mixed to be prepared into major feed; (2) green grass water removing: water removing treatment is performed in a pressure cooker; (3) microwave drying: green grass is subjected to drying treatment at two stages; (4) green grass pulverization: the dry green grass is crushed and pulverized until the green grass can pass through a 30-mesh sieve net; (5) fermentation liquid culture: fermentation liquid is prepared and is cultured under constant-temperature condition; (6) green grass powder fermentation: under the constant-temperature condition, saccharification and fermentation treatment is performed; (7) drying and pulverization: drying is performed at low temperature until the water content is 14 percent to 18 percent; a crushing machine is used for pulverization treatment; (8) feed pelletizing: the major feed, the dry grass powder and the functional feed are mixed according to a mass ratio of 20:15:4 to be prepared into granulated feed.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a processing method of green grass feed for young pigs. Background technique [0002] Pig feed can be divided into 8 types according to nutrient composition: protein feed, energy feed, roughage, green feed, silage, mineral feed and feed additives, among which protein and energy feed are the main components of pig feed, providing protein, sugar Nutrients such as meat and fat, minerals and feed additives provide medium and trace elements and functional nutrients to increase the immunity of pigs; grass feed can provide rich vitamins and reduce the incidence of vitamin deficiency diseases in pigs. At present, green grass feed in pig feed is mainly used in the form of green feed and silage. Green feed uses fresh grass roots, stems, and leaves for direct feeding. Green grass contains a lot of cellulose and lignin components, which pigs cannot digest Using untreate...
