Abstract

Manipulations in the rumen fermentation to prevent hydrolysis or biohydrogenation of fat has been found to affect the nature of fat entering the lower tract of the alimentary canal. This in turn, could affect the pattern of fat digestion and absorption. Since reports emanating in recent years have recognised the significance of altered level of blood lipids it was deemed fit to study the changes in blood metabolites of buffaloes after feeding them protected fat.

Abstract

Dietary supplements of oils and fats in the ruminant rations have invariably affected the metabolism in rumen. The same fat, however, when fed in protected form to cows did not show the adversaries seen earlier.

Abstract

Protein and NPN are known to contribute largely to ammonia pool in the rumen. The amount thus formed is mostly dependent on the type and quality of protein and carbohydrate in the diet. There is little doubt that all classes of carbohydrates (cellulose, starch or sugars) can well be utilized using ammonia as the major nitrogen source and about 80 per cent rumen bacteria could be grown with ammonia as a sole nitrogen source.

Abstract

The specific role of water in the processes of digestion of food, elimination of undigested residues, excretion of waste products of metabolism and dissipation of body heat in farm animals have been discussed at large in various reports. Both environmental temperature and plane of nutrition govern water intake as well as the ratio of water : dry matter intakes. The reports have also revealed that the dietary urea affect the water requirement of animals. The effect of water on regulating heat mechanism in Zebu, European and crossbred cattle have also been reported. However, much information is not available on the comparative aspects in these two species, i.e., zebu cattle and buffaloes.
