When rations containing, basically, sorghum grain were supplemented with urea, it was found that the urea affected the concentrations of certain fatty acids in the rumen and depot fat. On a ration of grain/sorghum silage similarly supplemented, isovaleric acid increased. There was a small affect of urea on the level of linoleic acid in the rumen of sheep which, however, was not significant at t...

Six ruminally cannulated steers, five Holsteins and one Hereford (250 to 295 kg), were fed 84% forage sorghum silage plus 16% supplement or 50% forage sorghum silage plus concentrate and supplement diets containing either no addition (controls), 1% sodium bicarbonate (NaI-1CO 3 ) or 2% sodium bentonite in a 2 X 3 factorial arrangement of treatments in a 6 • 6 Latin-square experiment with 3-wk p...

This research was conducted to investigate in situ degradation characteristics of maize, sorghum and sorghum-Sudan grass hybrids. whole plant of maize (TTM-815, DK-711), sorghum (SS-506, FS-5) and sorghum × Sudan grass hybrids (P-988, Grazer N2) were grown under semi-arid conditions and harvested at different maturity stages (mid-flowering (MF), milk-line (ML) and hard-dough (HD)) and ensiled. ...

Effect of Different Levels Speed Feed Sorghum Silage on Productive Performance, Milk Composition and Fatty Acids in Lactating Cows

Lack of forage in the winter dry season is a concern for cattle production tropical Brazil. Pasture renovation with silage might solve an immediate and help develop improved pasture condition after cropping. The present study was focused to compare quality monocropped sorghum intercropped Marandu grass and/or pigeonpea two row spacings. experiment carried out on sandy Oxisol São Paulo state Bra...

Water shortages are threatening the sustainability of irrigated agriculture in dry environments such as the Southern High Plains (SHP) of the U.S. Corn has been a staple silage crop grown to supply the enormous forage demand associated with dairy and beef feeding industries. The relatively high water use of corn, however, is limiting the extent to which corn can be grown. Although irrigated, co...

Polycultures, mixtures of different crop species in the same field, may provide both production and ecological benefits. Silage annual cropping systems incorporate polycultures take advantage species’ niche partitioning, potentially stabilizing yield variation due to abiotic stress. Using maize (Zea mays L.) silage as basis our 3‐year study, we tested impact on soil attributes replacing a fract...
