Environmental performance of aquaculture, chickens and milk in Brazil

The objective of this study was to analyze the environmental performance of aquaculture in Colorado of the West City, Rondônia State, Brazil. Fifteen fish farmers were interviewed. For data collection, structured interviews were carried out, using a questionnaire based on information supplied by the United Nations Food and Agriculture Organization (FAO). High temperatures also reduce the weight of organs in broilers, in order to reduce the metabolic rate of animals with consequent reduction of heat production. The protein level of broiler rations created under high temperatures may be reduced by supplementing with synthetic amino-acids without modifying their performance. Therefore, considering the different responses associated with the effect of high temperatures, it is evident that the broiler requirements vary not only due to the lineage but also in function of the thermal environment to which such animals are submitted in the different periods. The current industry demand for dairy products with extended shelf life has resulted in new challenges for milk quality maintenance. The processing of milk with high bacterial counts compromises the quality and performance.
