Abstract:
The objective of this study was to evaluate the effects of probiotics and encapsulated niacin supplementation on physiological parameters of growing Sahiwal female calves during summer season in arid region of Rajasthan. The present investigation was conducted at the Livestock Research Station, Kodamdesar, College of Veterinary and Animal Sciences, Rajasthan University of Veterinary and Animal Sciences for a period of 90 days during the months of June to August, 2019. Eighteen Sahiwal growing female calves having ages between 6-15 months were procured, such that the calves were the best representation of the population. Calves were housed in a well-ventilated and protected shed and were allocated to three different groups, each group consisting of six calves. The selected female calves were divided into three groups viz., group 1 (G-1), group 2 (G-2) and group 3 (G-3). Group 1 (G-1) calves received basal diet and the calves of group 2 (G-2) and group 3 (G-3) were fed the basal diet additionally supplemented with feed additives. Results revealed that the temperature humidity index (THI), which was used to express the effect of environmental parameters, gradually decreased as the season changed from summer to autumn. The values of physiological parameters, respiration rate (RR), and pulse rate (PR) were beyond the normal range which indicates that the animals were in the state of heat stress. Calves receiving supplementations along with the basal diet showed a reduction in summer heat stress was indicated by a significant decrease in the various stress indicators viz. respiration rate, and pulse rate
Highlights
- Studied on effect feed additives on physiological parameters.
- It can be effectively used as feed additives for alleviating heat stress in Sahiwal calves under the arid conditions of Western Rajasthan
