This study aimed to evaluate the productivity, growth performance and economic feasibility of polyculture of Nile tilapia Oreochromis niloticus and shrimp Litopenaeus vannamei at different stocking densities. Feed was provided based on fish requirements. The experiment was conducted at the Aquaculture facility of the Universidade Federal Rural do Semi-Árido – UFERSA, in a completely randomized design with five treatments and four replicates each. Treatments consisted of a tilapia monoculture with 2 tilapias.m-2; and polyculture with 2 tilapias.m-2 and L. vannamei […]

The aim of the analysis systems for rearing of beef heifers in black oats (Avena strigosa Schreb) and annual ryegrass (Lolium multiflorum Lam) pasture was to determine animal performance and economic relationships. Data were analyzed from four grazing trials performed at the Federal University of Santa Maria, RS. Production costs, animal production and gross margin were evaluated. The trials were conducted from 1998 to 2001. The feeding systems were YEAR 1: STP- animal supplementation during entire pasture cycle; SAS – […]
