Abstract
In this study, the effects of in-shelter gas concentration on milk yield and
total dry matter intake (TDMI) of buffaloes during the spring and summer
periods were investigated. The research was carried out in a shelter with
20 main Anatolian buffaloes between March and July. Values for
temperature, relative humidity, air velocity, and CH4, NH3, and CO2 gases
were recorded in the shelter. Data records were collected continuously for
24 hours for 4 days. Milk yield and DMI of buffaloes were also
determined. As it was observed, higher air velocity in the house reduces
the methane gas levels (P<0.01). The regression equation between milk
yield and relative humidity was Y= 6.011-0.03RH and showed a negative
and low degree correlation. It was illustrated that TDMI varied between
11.00 ± 0.12-13.20 ± 0.06 kg during the summer. The difference observed
between months in terms of feed intake was found to be statistically
significant (P<0.05). Although the milk yield of water buffalo was low in
March, it increased in April and May. However, there was a decrease in
DMI (0.50 kg/day) and milk yield (264 mL/day) for an increase of + 1 °C
in air temperature. The recorded values for CO2 concentration in the
buffalo shelter during the summer period varied between 620-1120 ppm.
Considering the obtained results, NH3 and CO2 gas levels in the shelter
were below the higher limits and can be considered as not dangerous for
animal and human health. It was determined that regression equation
between feed intake and temperature was Y= 9.901 + 0.089T**,
regression coefficient was R2= 0.19 and correlation coefficient was r=
0.44 (P<0.001).
