ThesisItem Open Access Monitoring certain physiobiochemical parameters of post weaned crossbred kids raised under three different climate resilient housing system(College of Veterinary Science, Assam Agricultural University, Khanapara Campus, 2022-09) Patgiri, Dhiman; Dutta, ArupThe present experiment was conducted to study the growth and physio-biochemical performances of post-weaned (90 days) female crossbred kids (Beetal × Assam Hill Goat) kept under three different climate resilient housing system (i.e., Shed-A, Shed-B and Shed-C) from weaning (90 days) till the attainment of puberty. A total of 21 numbers of post-weaned (90 days) female crossbred kids (Beetal × Assam Hill Goat), maintained in intensive care of management and fed a uniform ration in accordance to ICAR, 2013 feeding standard were randomly divided into three groups of average equal body weight having 7 animals in each group and housed in three different housing system which differed in terms of their ventilation system, materials used, colour, ground clearance etc. Temperature, relative humidity and THI of the ambient surrounding and inside the three sheds were recorded thrice daily viz., morning, afternoon and evening hours during the experimental period and it was found that temperature and THI varied significantly among the ambient surrounding and the three Sheds with lowest temperature and THI recorded in the Shed-B i.e., having side ventilation with walls and floor made of bamboo material. The physiological parameters related to thermal stress viz., respiratory rate, pulse rate and rectal temperature were recorded at alternate days in the morning hours during the experimental period and statistical analysis revealed significant differences (P<0.01) in those parameters with the lowest value recorded in the Shed having the lowest THI. The body weight measurement was done at fifteen days (Fortnightly) interval and statistical analysis revealed significant differences (P<0.01) in the body weight of the animals in the different housing system and the housing system having lowest THI showed highest body weight gain (9.75±0.24 Kg) compared to the animals of other housing systems. Similarly, the age of attainment of puberty was attained by close monitoring of the animals for signs of puberty and statistical analysis revealed significant differences (P<0.01) in the age of attainment of puberty with the lowest age (200.43±5.96 Days) of attainment of puberty was found in animals reared in the system having the lowest THI value. Blood samples were collected at fifteen days (Fortnightly) interval for the analysis of certain haemato-biochemical parameters. Statistical analysis revealed non-significant differences in the Hb, RBC, Glucose and SOD concentrations. Although, there was an apparent decrease in the SOD (1.25±0.03 u/g) concentration in the housing system having lowest THI value. The PCV concentration showed significant differences (P<0.01) among the various housing system with the minimum PCV (18.86 ±0.16 %) value was recorded in the animals housed in the Shed having lowest THI. Analysis of variance revealed that the Cortisol, T3 and T4 concentration showed significant differences (P<0.01) among the animals housed in the different housing system. Thereby it can be seen that housing system having strong implication on various physiobiochemical parameters of an animal and also has the potential to ameliorate the effect of thermal stress on animal.
