Twenty lactating
crossbred cows (½ Holstein Friesian x ½ Tharparker) were
randomly divided into 4 groups of 5 animals each and they
were reared under four housing conditions viz; (T1) loose
house, (T2) loose house (LH) + mud plaster roof house, (T3)
LH+thatch roof house and (T4) conventional barn. The maximum
ambient temperature in T1, T2, T3 and T4 shed was
23.96±0.38, 22.80±0.33, 23.07±0.23 and 23.17±0.23 °C
respectively. The maximum temperature, was significantly low
(P<0.01) in T2, T3 and T4 shed as compared to T1 shed. While
relative humidity (RH) was significantly (P<0.01) higher in
T4 as compared to T2 & T3. However, there was no significant
(P>0.05) differences were observed between T4 and T1 and T2
and T3 house, respectively. While Temperature Humidity Index
(THI) was significantly (P<0.05) higher in T4 as compared to
T3, T2 and T1 houses. The daily intake of DM, DCP, TDN and
water intake was significantly influenced (P<0.01) by
shelter management. The daily DMI was more (P<0.01) in T2
(12.31 kg) and T3 (12.02 kg) groups as compared to T1 (11.46
kg) and T4 (10.94 kg) groups cows, respectively. The DCP
intake was significantly (P<0.05) higher in T2 (857.27 g) as
compared to T3 (793.19 g), T4 (721.58g) and T1 (717.15 g)
group cows. The TDN intake was 6.41±0.016, 7.31±0.10,
6.94±0.22 and 5.94±0.15 kg in T1, T2, T3 and T4
respectively. The daily TDN intake was significantly
(P<0.05) higher in T2 and T3 groups as compared to T4 and T1
groups cows. The voluntary water intake (VWI) per kg DMI (L)
was significantly (P<0.05) higher in T1 group as compared to
T2 and T4 groups animal. There was no significant difference
was observed between T1 and T3 groups animal. The
digestibility of CP (68.56%) in T2 and T4 (69.82%) group
significantly (P<0.05) higher as compared to T1 and T3
groups animal. The milk yield was significantly (P<0.05)
higher in T2 group than T3, T4 and T1 groups animal. It was
concluded that the provision of mud plaster roof house
improved the intake and utilization of nutrients in
lactating crossbred cows.
