Impact of Water Spraying On Broilers Health before Transportation

Transportation of broiler chickens from farm to slaughtering locations is one of the aspects in broiler production that highly affects the quality of meat produced. During the production process, transportation is actually a short duration process. However, this short duration process often causes a big loss due to the stress triggered by the transportation process. The losses come from the high mortality rates during transportation and the reduction of meat quality due to the stress1.

The effect of transportation is worsen by the fact that chickens do not have sweat glands and all parts of their body are covered with the feathers causing chickens suffering from acute heat stress during the transportation2. As a result, glycogen is then broken down excessively and lactic acid is piled up, making the meat produced to have low pH, pale color, soft texture and watery3. Therefore, to maintain the normal quality of broiler meat during the transportation process, all factors causing the chicken to suffer from heat stress should be minimized.

One practice that has been widely used by farmers is water spraying of the chickens shortly prior to transportation to minimize the negative effects of solar radiation and heat load. However, scientifically, the practice effects on hematological status and meat quality of the chickens have not been identified. Therefore, a new study was designed to evaluate the effects of water spraying prior to transportation on hematological parameters and meat qualities of transported chickens4.

The water-spraying treatment given in the study could minimize the effects of heat stress on meat quality, as shown by pH, water holding capacity, cooking loss and tenderness of the meats of water-sprayed broiler chickens prior to transportation similar to those of control broiler chickens. The sprayed water acts as a conductor for body-heat dissipation to the environment.

The result is the maintenance of body temperature in a comfortable condition that is similar to the condition of control broiler chickens without transportation. As a result, meat quality of the water-sprayed broiler chickens prior to transportation was similar with those of control broiler chickens without transportation.

The results of the study confirmed that transportation reduces the quality of meat and the negative effects of transportation stress can be minimized by water spraying of broilers chickens shortly prior to transportation. Therefore, to minimize the effect of transportation stress on meat quality, it is advisable to give water spraying prior to transportation.
