The straw puffed biological feed is the green ecological feed produced by new-type straw high-tech processing technology.The product is compressed and wrapped into a cylindrical shape and thus figuratively referred as "canned feed".Compared with dry straw, the nutrient content in straw expanded biological feed is greatly improved.Inspected by authoritative department, the content of crude protein rises by more than 50%, and the content of crude fat increases by more than 65%. The content of cellulose and hemicellulose, which are not easy for digestion and absorption have been reduced, and the lignin content decreases by more than 50%. The straw puffed biological feed has a extensive range of application, which is widely used in pigs, cattle, sheep, deer, geese and other animal breeding . Compared with dry feed, straw puffed feed has the following advantages:
First,the feed is not perishable after vacuum packaging,storage period is up to 18 months or more, and it’s soft, delicate, and palatable, nutritious, digestible and absorbable.
Second,nutritional components of straw will increase and improve the utilization rate,it also can replace parts of concentrated feed and reduce the cost of feeding;
Third, the feed contains beneficial bacteria which is involved in the gut flora livestock balance, enhances animal immunity, reduces the incidence of disease and promotes the growth of livestock;
Fourth, it can improve meat and milk quality, increase milk fat rate, raise protein content and lower cholesterol content.
In order to prove the authenticity of the straw puffed biological feed, we have conducted feeding contrast tests respectively with pigs, cows, sheep over three years with the domestic famous universities and research institutes, the following results are obtained:
(1)20% concentrated feed is replaced by straw puffed feed and used for feeding fattening pigs. Under the precondition of no negative effect on growing pigs, the feed cost could be saved by about150-240 Yuan, so the raising cost is reduced greatly. The straw expanded biological feed can supplement the necessary fiber components of gestation and lactation sows, effectively solve the problem of constipation of sows under the action of beneficial microorganism, reducing the chances of the weak pigs and stillbirth, raising the newborn weight of suckling pig.
The use of straw extruded bio-feed cattle can save 40%-50% concentrated feed during the fattening period.The average daily cost per cow is reduced more than 8 Yuan,the profit from each cow can be increased by more than 800-1500 Yuan,and the breeding profit has been significantly improved.
When the straw extruded biological feed is used for fattening sheep breeding,without affecting the daily weight gain, it can save 40%-50% concentrated feed. The profit from each fattening sheep during fattening period can be increased by more than 160-180 Yuan.The quality of meat is as good as those of natural grazing sheep.The sheep’s immunity obviously have been enhanced and the morbidity is extremely low,so the medicine cost is reduced.
