The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

Sixteen crossbred Holstein × Zebu cows (groups from ½ to ¾ of Holstein × Zebu) at third of fourth lactation were allotted to four 4 × 4 Latin squares to evaluate the economical viability of increasing dietary concentrate level. Cows presented previous milk yield from 2,500 to 3,000 kg, adjusted for 300 days, and grazed pasture during the rainy season, and with 110 days of laction in the beginning of the experimental period. Because of the prices of milk and concentrate during the experiment, it is not interesting to use concentrate in the diets of milk cows fed sugar cane. If the productive and economical aspects toghther and the prices of R$ 0.70 and R$ 0.50 for the milk and the concentrate, respectively are considered, the use of 24% concentrate in the diet is the most interesting option for dairy cows fed sugar cane.
