Evaluation of the feeding value of tea waste for milk production in cows
An investigation was carried out to find out the feeding value of tea waste for milk production in cows. A total of nine Jersey x Sindhi crossbred cows were divided into three groups of three animals each and fed tea waste in their concentrate ration at 0, 15 and 25 per cent levels. A switch – ove...

A total of nine Jersey x Sindhi crossbred cows were divided into three groups of three animals each and fed tea waste in their concentrate ration at 0, 15 and 25 per cent levels. A switch – over design was used for the experiment. From the results it was revealed that feeding of tea waste upto 25 per cent in the concentrate mixture has no significant influence on the body weight of the animals. It was found that the milk production of the control animals having no tea waste in their rations was found to be significantly higher as compared to that of the animals getting tea waste at 15 or 25 per cent level. Eventhough the animals of the control group produced a significantly higher yield of butter fat and total solids in milk, their respective percentage remained almost the same for all the treatments thereby indicating that the quality of milk remained unaltered. In terms of fat – corrected milk and solids – corrected milk the animals of the control group had a significantly higher yield than those of the animals in the experimental group. No significant difference was noticed in the percentage of solids – not – fat or in total solids – not – fat yield among the three groups. The physiological status of the cows in all the groups as revealed by the study of the blood values was normal and satisfactory. The feeding of tea waste upto 25 per cent in the concentrate mixture did not bring about any significant difference in the physical and chemical constants of butter fat. On the basis of economics, the ration containing tea waste at 15 per cent level can be considered as equivalent to the control feed containing no tea waste and the ration having 25 per cent tea waste was found to be more profitable for milk production. | |
