Story in Brief The influence of roughage source on digestion of :1 high grain diet was measured with 24 Hereford-Angus steers. The six roughages tested were cottonseed hulls, prairie hay, alfalfa hay, sorghum plant silage and two varieties of corn plant silage. The diet consisted of 82 percent whole shelled corn, 10 percent roughage and 8 percent supplement. Daily feed intake was restricted to ...

In many parts of the world, poor quality roughages low in nitrogen are the only food available to the grazing ruminant. Experiments have shown that under some conditions, still not clearly defined, urea can improve both the digestion and intake of these roughages, and also the nitrogen status of the animal. However, there are reports from both the laboratory and the field, which indicate that u...

In the last decade an increasing number of farmers worldwide have adopted the technique of ammoniation as a means of increasing the utilisation of roughages by ruminants, Our work has identified problems with ammoniation which are similar to those encountered with ammoniated molasses in the 1950%. Since July 1984 there have been several outbreaks of hyperexcitability in cattle fed ammoniated ro...

In Australia, the main interest in urea. feeding to ruminants is the possibility of using this substance as a protein supplement for roughages so high in fibre and low in protein that they constitute sub-maintenance rations for animals grazing them. Several workers have shown that the loss of weight of ruminants fed such roughages can be prevented, or reduced, by adding a supplement of urea and...

On the Balkan Peninsula, sheep lamb during the winter months, which necessitate to house and feed the lambs in indoor production systems. The proper nutrition of growing lambs is essential for their growth and development during the winter month, and the aim is attaining the desired live weight over a short time period with low feed expenditure. During that period, the major part of the ration ...

The effects of pre-treating different types of roughages with alkali on the efficacy of exogenous fibrolytic enzymes for improving their digestibility were studied in vitroin factorial arrangement 4 × 3 × 5 (enzyme, treatment and roughage types). Two fibrolytic feed enzymes novozyme (N) and celloclast (C) their combination (N+C) were evaluated for their potential to improve in vitrodegradation ...

The aim of this study was to compare chemical composition, relative feed values, and in vitro true digestibility the giant fennel (Ferula communicus L. -F), helis (Prangos ferulacea -H), gum- tragacanth (Astragalus microcephalus WILD. -G) leaves oak tree (Quercus robur -O), a naturally growing plant on high- altitude plateaus Eastern Anatolia, with those alfalfa. In digestibilities (IVTD) rough...
