Abstract

Water is a vital nutrient in broiler farming and is present throughout intensive farming. Consumption in correct quantities from housing is important for the formation of intestinal villi and to stimulate feed consumption. It must be offered without restrictions, with acceptable physical-chemical quality and at an ideal consumption temperature, as birds are monogastric animals and prefer to consume water at a temperature of 24°C. To avoid variations in water consumption, water temperature control measures, such as shading reservoirs and grounding pipes, are increasingly used on broiler farms. Adjusting drinkers, depending on the bird's growth, is of primary importance so that consumption is balanced within a given bird population. The objective of the present study was to evaluate the effects of painting water tanks with a reflective paint that does not absorb heat, with the treatment boxes being painted white with this paint and the control group with the water tanks in the standard blue color. manufacturing process, drinking water temperature, and its impact on water intake in broiler chickens raised in commercial warehouses located in the Mineiros Goiás region. The birds are from the Ross lineage, raised from 1 to 47 days, housed in commercial warehouses. dark house type masonry, with automatic feeders and automatic nipple drinkers. Daily management, as well as the environmental conditions provided to the animals, were in accordance with the recommendations in the lineage manual. Regarding the temperature of the water in the nipple, no statistical differences were found between the treatments with painted box and box without painting, with no changes in consumption, and the results show that the water infrastructure of the farms is the main factor for water temperature. that reaches the animals for consumption, since the effects of external temperature and radiation mean that the water temperatures in the water lines in both treatments reach very close to the animals, where there is a need to bury the pipes at a greater depth. When it comes to the temperature of the boxes, both the comparison of the blue and painted boxes showed statistical differences if the effect of the time of day p<0.05 is not taken into account. Maintaining water at the appropriate thermal comfort temperature (approximately 24ºC) is essential for the successful production of these birds, and the main factor for this to occur is understanding the water infrastructure of each property.
