Abstract
This invention encompasses protein-protected ruminant feed comprising oil seed meal, hulls, and water that has been cooked to give a cooked meal having a temperature of at least 200.degree. F. and a moisture content of from 21 to 26 wt. % and thereafter drying and cooling the moist cooked feed to give a protein protected ruminant feed. The protein protected ruminant feed is less digestible in the rumen and thereby enhances ruminant growth and milk production.
Claims9
A process for manufacturing a cooked protein protected ruminant feed comprising the steps;
- (a) mixing oil seed meal with hulls to give a combined feed solids mixture having a hull/oil seed meal weight ratio of from about 1:100 to about 10:100;
- (b) adding water to the combined feed solids mixture in an amount ranging from about 30 to about 50 wt. % of the oil seed meal weight in the combined feed solids mixture to give a moist meal feed;
- (c) cooking the moist meal feed in a cooker for a period of time sufficient to give a moist cooked meal having a temperature of at least 200.degree. F. and a moisture content based on the weight of oil seed meal in the combined feed solids mixture of from about 21 to about 26 wt. %;
- (d) drying the moist cooked meal in a dryer at conditions of temperature and time sufficient to give a dried meal having a moisture content based upon the weight of oil seed meal used in the combined feed solids mixture of from about 12 to about 16 wt. %;
- and
- (e) cooling the dried meal in a cooler to give a protein protected ruminant feed having a temperature less than 25.degree. F. above ambient temperature.
A process for manufacturing a cooked protein protected ruminant feed comprising the steps;
- (a) mixing soybean meal with soybean hulls to give a combined feed solids mixture having a soybean hull/soybean meal weight ratio of from about 3:100 to about 6:100;
- (b) adding water to the combined feed solids mixture in an amount ranging from about 33 to about 40 wt. % of the weight of soybean meal in the combined feed solids mixture to give a moist meal feed;
- (c) cooking the moist meal feed in a stacked cooker for a period of time sufficient to give a moist cooked meal having a temperature of at least 200.degree. F. and a moisture content based on the weight of soybean meal in the combined feed solids mixture of from about 21 to about 26 wt. %;
- (d) drying the moist cooked meal in a rotating drum dryer at from about 100.degree. to about 150.degree. F. for a period of time sufficient to give a dried meal having a moisture content based upon the weight of soybean meal used in the combined feed solids mixture of from about 12 to about 16 wt. %;
- and
- (e) cooling the dried meal in a cooler to give a protein protected ruminant feed having a temperature less than 15.degree. F. above ambient temperature and having a moisture content of from about 12 to about 15 wt. % of the weight of soybean meal in the combined feed solids mixture.
