dc.description.abstract | The research was conducted to study on effects of environmental management in evaporative cooling system (EVAP) house on productive performance of layer pullets. This study divided into 2 experiments.
Experiment 1 was conducted to study on temperature and air velocity in evaporative cooling system (EVAP) house on productive performance of layer pullets. Four thousand and eight hundred
layer pullets were raised on battery cage with 5 birds per cage and assigned in a Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of four blocks (four houses) and followed different temperature and air velocity in raising area of evaporative cooling system (EVAP) house as front area central area and back area. Results showed that temperature and air velocity in front area was grater body weight gain (BWG), average daily gain (ADG), and feed conversion ratio (FCR) of layer pullets than layer pullets were raised in back area of evaporative cooling system (EVAP) house (P<0.01)
Experiment 2 was conducted to study on light color and number of H-Flame battery cage row in evaporative cooling system (EVAP) house on light intensity and productive performance of layer pullets. Nine thousand and six hundred layer pullets were raised on H-Flame battery cage with 5 birds per cage and assigned in a 2x4 factorial in Randomized Completely Block Design (RCBD) experiment with two factors. Factor A was light color comprised of range and blue). While, Factor B was number of battery cage row comprised (first row, second row, third row, and fourth row). Each treatment consisted of four blocks (four houses). Results showed that interaction between factor A and B on light intensity and uniformity of layer pullets with highly significantly different (P<0.01). However, interaction between factor A and B, and main effect (factor A and B) were investigated on body weight gain (BWG), average daily gain (ADG), and feed conversion ratio (FCR) (P>0.05).
The data from this research was suggests the important for implicate to improve the egg production industry in further success. | en_US |
