Use of Molasses Containing Urea as a Supplement to Pangolagrass Pastures in Northeast Mexico

Abstract

Supplements of molasses, molasses + 3% urea, and molasses + 6% urea at a level of approximately 1 kgJhead/day on pangolagrass pasture during the winter and spring months resulted in significantly increased weight for s Zebu x X Criollo bulls. Urea was more effective during the winter months when forage availability was at its lowest, than during the spring months. It is suggested that the use of pangolagrass pasture with molasses and urea supplementation when appropriate could significantly increase production from rangeland. M. H. Butterworth and D. L. Huss are Using statistics provided by FAO animal production specialist and range management specialist at FAO of the United (1967), it may be calculated that about 6 Nations. E. L. Aguirre and A. C.

Liquid supplementation of grazing cows and calves

“…found that yearling heifers responded to supplementation when grazing native range but not improved pastures. Butterworth et al (1973) reported that supplementation was more effective in the winter when forage availability was lowest, than in the spring when more forage was available.…”

“…It seems probable that purebred Angus cows grazing improved pastures would produce more milk than cows grazing native range. , Butterworth et al (1973), andLandlands and reported that grazing animals responded more to supplementation on lower quality forages. Bowman et al (1995b) concluded that performance and forage intake by supplemented animals were confounded by pasture condition and forage quality.…”
