Embodiment 1

[0029] A method for preparing yellow storage of corn stalks for ruminant livestock breeding, the steps of which are:

[0030] (1) The content of lactic acid bacteria is 1×10 12 The CFU / g lactic acid bacteria agent was activated in tap water at 20° C. for 1 hour according to the weight ratio of 1:100. The dry alkyl polyglucoside was dissolved in tap water at 20° C. for 10 minutes at a weight ratio of 1:100.

[0031] (2) Crush the corn stalks after harvesting corn cobs into small sections with a length of 3 cm, measure the moisture content of the corn stalks to be 56%, and then spray clean water evenly on the corn stalks according to the ratio of 200:30 by weight of the corn stalks and clean water on straw.

[0032] (3) Mix the water-sprayed corn stalks obtained in step (2) with corn flour in a weight ratio of 100:1 and mix evenly.

[0033] (4) Lactic acid bacteria obtained in step (1) and alkyl dry polyglucosides were respectively divided into 1 × 10 10 The concentration of...

Embodiment 2

[0040] A method for preparing yellow storage of corn stalks for ruminant livestock breeding, the steps of which are:

[0041] (1) The content of lactic acid bacteria is 1×10 12 The CFU / g lactic acid bacteria agent was activated in tap water at 30° C. for 1 hour according to the weight ratio of 1:100. The dry alkyl polyglucoside was dissolved in tap water at 30° C. for 10 minutes at a weight ratio of 1:100.

[0042] (2) Crush the corn stalks after harvesting corn cobs into small sections with a length of 4 cm, measure the moisture content of the corn stalks to be 58%, and then spray the clear water evenly on the corn stalks according to the weight ratio of 200:40 by weight of the corn stalks and clear water. on straw.

[0043] (3) The water-sprayed corn stalks obtained in step (2) and corn flour are uniformly mixed in a weight ratio of 100:1.5.

Abstract

The present invention discloses a preparation method of a corn stalk yellow silage for ruminant livestock breeding. The preparation method comprises the following steps: (1) a lactic acid bacterium agent is activated in tap water according to a weight ratio; and alkyl polyglycosides are dissolved in the tap water according to a weight ratio; (2) after corn cobs are harvested, corn stalks are crushed; the moisture of the corn stalks is determined; then the corn stalks and clean water are mixed at a weight ratio; and the clean water is sprayed evenly on the corn stalks; (3) the obtained clean water sprayed corn stalks and corn flour are mixed evenly according to a weight ratio; (4) the obtained lactic acid bacteria and alkyl polyglycosides are sprayed on the obtained stalks obtained in the step (3) respectively at concentrations of 0 x 10<10> CFU / kg-2 x 10<10> CFU / kg and 0 g / kg-0.3 g / kg; and even mixing, then compacting, sealing and fermenting are conducted; and (5) when an obvious sourand fragrant smell appears, the fermentation is terminated to obtain the yellow silage feed. The method is simple in technology, low in operation and easy to operate, and improves the yellow silage quality of the corn stalk yellow silage.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a method for preparing yellow storage of corn stalks for ruminant livestock breeding, which is suitable for ruminant livestock breeding feed for beef cattle, mutton sheep and dairy cows. Background technique [0002] Corn stalk is one of the most abundant crop by-products after harvesting corn in northern my country. Because of its large volume and high crude fiber content, it is one of the important roughage resources for ruminant livestock. It is very important for maintaining animal intestinal health and improving lactation. The milk fat percentage plays an important role. However, in actual production, most of the utilization of corn stalks is limited to direct feeding after simple crushing, or burning after drying in the field, which brings great environmental pollution. Yellow storage of corn stalks as feed can not only improve the effective utilization of nutrient...
