Twenty (n=20) healthy indigenous Ghungroo male piglets (Sus domesticus) weighing on an average 3.5±2 kg and aged around 2-3 months were selected for the experiment and randomly divided into four groups of five piglets each. In group 1(control), the piglets were castrated surgically whereas treatment groups (T1, T2 & T3) of each piglets were castrated by intra- testicular injection of chemical sterilant of varying concentrations. The mean rectal temperature for control group (99.59±0.150) in different time intervals were lowest when compared with all the treatment groups (T1=102.21±0.180; T2=101.67±0.270 and T3=101.31±0.170) (p< 0.05). However, there was no significance difference (p< 0.05) among the three treatment groups (T1, T2 & T3). The mean respiration rate for control group (30.37±0.130) was found lowered and highest in T1 group (36.06±0.123). However T1, T2 and T3 did not differ significantly from each other (p< 0.05). The overall means of pulse rate showed significant differences between treatment groups (p< 0.05). However there was no significant difference between control and T3. It can be concluded from the current experiment that there was no detrimental effects of chemicals on physiological variables in piglets and can be used as a substitute for surgical castration.

Due to certain inherent traits such as high fecundity, improved feed conversion efficiency, prolificacy, early maturity, short generation interval, and higher dressing percentage (Talukdar et al., 2020) [9] , pigs have a tremendous potential to give a faster economic return to farmers when compared to other livestock species. Pigs are twice as efficient as ruminants in terms of productivity (Mpofu and Makuza, 2003) [6] . Castration is one of the most important management activities of the farm in pig husbandry. Castration is practiced primarily to avoid boar taint to prevent skatole and androsterone accumulation in fat which is an unpleasant odour in the meat of an uncastrated male pig (Backus, 2014) [1] and is a carcass quality concern. Male pigs have been surgically castrated since 4000-3000 B.C. Surgical castration is now widely viewed as a stressful procedure that has detrimental consequences for animal health and welfare (Zamaratskaia and Rasmussen, 2015) [11] . Chemical castration has been proposed as a non-invasive castration technique in domestic animals. It has been used as a simple and low cost technique for castration in pig (Giri et al., 2002) [3] . Advantages of non-surgical chemical castration are apparent reduction in pain and stress, and relief from post-operative complications such as haemorrhage, hernia, infection, myiasis and other surgical sequelae (Koger, 1978) [5] . Physiological parameters are always correlated with physiological status of the animal, indicating the environment’s positive or negative effect on that animal. The experiment was conducted with an objective to evaluate the changes in physiological parameters after surgical and chemical castration in Gunghroo male piglets. 2. Material and Methods The present experiment was carried out in Pig unit of the composite livestock farm of ICAR- Indian Veterinary Research Institute, Eastern Regional Station, Kalyani, Nadia district, West Bengal located at 22° 56' 30'' N latitude and 88° 32' 04'' E longitude, and 9.75 meters above mean sea level altitude.
