Behavioral pattern of Rohilkhandi kids under different feeding systems
Abstract
Aim: The present study designed to evaluate the effect of different feeding systems on the behavior of local Rohilkhandi kids. Materials and Methods: A total of 21 growing goats (local goat of Rohilkhand region), weighing around 7-11 kg and aging 4-5 months, were used. These animals were kept in three groups. Group I was fed un-chopped green fodder in circular feeder (newly designed). Group II was fed un-chopped green fodder in linear feeder that was similar to the existing farm practice. Group III was fed chopped green fodder in linear feeder (modified version). Amount of concentrate and dry fodder fed was kept constant for all the three groups subject to equal increment in accordance with their increasing age. Adlibitum green fodder was made available to the animals. The experiment was conducted for 3 months. On-going behavior was recorded each day 4 h (2 h in the morning from 9:00 am to 11:00 am, after offering the feed, and same was repeated for 2 h in the afternoon, i.e., from 2:00 pm to 4:00 pm) was made between 9 am and 5 pm. The individual behaviors, viz., feeding, drinking, lying down, ruminating, idling, butting, pressing, pushing, frontal clashing, and physical displacement at feed barrier (active and passive: Without physical contact) of the goat were recorded using time-sampling method. Further, incidental activities such as defecation and urination were also recorded. Results: Among all the groups, butting, head to head, and pushing were the common agonistic behavior found but values did not differ significantly. The pushing while feeding was relatively less in Group II (0.22±0.04 min) which differed significantly (p<0.05) from the other two groups. The idling time was found significantly (p<0.05) lower in Group II (1.68±0.21) as compared to Group I (4.67±0.52) and Group III (4.27±0.56). Time spent in rumination near the feeding trough as well as away from the feeding trough was also significantly higher in Group I (p<0.05) than the other two groups. Other minor activities, viz., defecation and urination were negligible. No stereotypic activities were observed. Conclusion: It was concluded that provision of un-chopped fodder in circular feeder could only simulate natural feeding behavior of goat but did not give any added advantage. Further, feeding chopped fodder in linear feeding trough lead to increased consumption and more time is spent on feeding than on agonistic behavior as compared to the other two groups.
