Abstract
The 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.
