Economics of feed additives supplementation in KF heifer during summer stress

Abstract

The objective of this study was to access the economics of protected fat plus yeast, niacin, zinc and chromium dietary supplementation on Karan Fries (KF) heifers. The basal ration for both the groups were same. However, the treatment group was supplemented with protected fat (2.5% of dry matter intake (DMI)), yeast (10g /animal/day), niacin (6 g/animal/day), zinc (40mg/kg DMI) and chromium (1.5 mg/kg DMI). Additional amount spend on treatment group animal is Rs 1755.35 during the experimental period which can be easily compensated if the treatment group animal attains sexual maturity earlier by 15 days only. The present study concludes that the supplementation of above feed package in the ration of growing KF heifers during summer stress period is economically viable proposition.
