Potential use of Tinospora cordifolia as a herbal supplement in dairy animals: a review.

Supplementation is an integral part of modern dairy-feeding practices which mainly emphasise on higher production. Different supplements have been utilized by the farmers according to the need and action of supplements. Tinospora cordifolia (TC) is one such herbal supplement which can be utilized to feed dairy animals either alone or in combination with other supplements. TC is a herb found in tropical countries and having number of medicinal properties. Beneficial health effects of TC include immunostimulation, protection against inflammation and bacterial action, hepatoprotection, antioxidant and antineoplastic effects. Available studies on TC supplementation in dairy animals have shown a positive effect on health, body parameters and production performance. Supplementing TC is economically feasible, and it can be adopted by farmers as it helps in improving their net income. However, more research is needed in the field of dairy animals to explore the full potential of this herb. This review is written with the objective of highlighting the possibilities of using TC in dairy animal rations and promoting research in the concerned field to fill the gaps in knowledge. Thorough knowledge about TC and its effect in dairy animals can add a new concept to the supplementation process and developments of dairy rations.

Effect of mother bonded rearing on growth, health and physiological state of Murrah buffalo calves.

We investigated the effect of different types of mother-young contacts (fenceline, restricted and no contact) on the health, growth performance, behaviour and physiological state of Murrah buffalo calves. A total of 24 calves were allocated to three groups of 8: NCM (no calf-mother contact), RCM (restricted calf-mother contact) and FCM (fenceline calf-mother contact). At three months of age, the FCM calves had a higher average body weight (58.6 ± 1.5 kg) than the RCM (52.8 ± 1.3 kg) and NCM (53.6 ± 1.3 kg) calves (P < 0.05). The average daily gain (ADG) at three months of age was greater in FCM (0.6 ± 0.1 kg/d) than RCM (0.5 ± 0.1 kg/d) and NCM (0.5 ± 0.1 kg/d) calves (P < 0.05). The mean immunoglobulin G (IgG) concentrations were significantly greater on d 7, 28, 42 and d 56 of sampling (P < 0.05 for all comparisons) in FCM than RCM and NCM calves. The mean cortisol levels were highest in the NCM calves followed by RCM and the lowest values were observed in FCM calves on d 0, d 7, d 28, d 42 and d 56, respectively (P < 0.05, for all recorded days). The diarrhoea score and eggs per gram of faeces (EPG) were significantly greater in the NCM group compared to the RCM and FCM groups. The time spent in cross sucking, licking inanimate objects and self-licking was greatest (P < 0.05) in NCM calves, followed by RCM calves, and was almost non-existent in the FCM group on all the recorded weeks. Time spent in backward ear position was greater (P < 0.05) in FCM than RCM and NCM calves. The average time spent in forward ear position was greatest (P < 0.05) in the RCM calves followed by NCM with the lowest time observed in FCM calves. The mean duration of time spent by calves in the asymmetrical and axial ear position differed significantly (P < 0.05) among NCM, RCM and FCM calves, P < 0.05. The full and fenceline buffalo calf-mother contact system showed higher growth rates, lower levels of stress responses, oral stereotypies and eggs per gram of faeces. In addition, ear postures may be used as a dependable, and reliable measure of positive, low arousal emotional states.
