The objective of this research was to characterize the effluents of fish ponds of Macrobrachium amazonicum cultured in different densities of farming and to analyze the daily variation (24 hours) of the vertical temperature and oxygen saturation profile of the water column of the ponds. The study was conducted during a period of three months using 12 rectangular 100 m2 earthen ponds supplied with M. amazonicum individuals in four densities of farming (40, 60, 80 and 100 individuals/m2), each one […]

Body weight gain of 103 Nelore calves until 20/21 months old when weaned on cultivated pasture and supplemented during the dry period was evaluated during three years to obtain steers with body weight to be finished immediately at fedlot. At the beginning and end of supplementation period, the animals averaged body weight and age of 189.51± 21.08 kg and 254 ± 29.22 days and 242.38 ± 29.22 kg and 400 ± 31.08 days, respectively. The mean daily feed intake was […]
