    A STUDY ON BEHAVIOURAL TRAITS AND PERFORMANCE OF HASSAN LAMBS REARED ON DIFFERENT FLOOR TYPES UNDER INTENSIVE SYSTEM
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2022) BASAVARAJ, H. KAREBHARAMANNAVAR; GURUPRASAD, R.
    A study was conducted to assess the effect of different floor types (T1: Mud/soil, T2: Concrete, T3: Concrete with Rubber Mat) on growth performance, feed and DMI, biometry, physiological parameters, blood-biochemical parameters, behavioural traits, dirt score, EPG and OPG count, hoof condition in growing Hassan lambs under intensive system. Statistical analysis of the obtained data revealed nonsignificant difference among the treatment groups with respect to, body weight gain, feed and DMI, biometric measurements, physiological parameters (pulse rate, respiration rate), blood-biochemical parameters, overall mean values of EPG and OPG count, hoof length. Whereas, the ADG (g) and rectal temperature (ºF) were statistically significant (P<0.05). The time (min) spent on standing and lying by lambs had significant difference (P<0.05) among the three floor types. The highest standing time (min) was recorded in T2 group followed by T1 and T3 groups, while lying time (min) was significantly (P<0.05) lower in T2 group compared to T1 and T3 groups. There was no significant difference of time (min) spent on eating, drinking and licking behaviours. Significantly lower (P<0.05) dirt score was observed in lambs reared on mud floor than concrete floor followed by rubber mat floor. The lambs reared on rubber mat floor shown higher dirt score throughout the study period. Results of the present study indicated that the lambs reared on rubber mat floor were more comfortable than the lambs reared on mud and concrete floor.
