| This study aimed to evaluate the inclusion of palm kernel cake in the diet for lactating crossbred cows in feedlot system, and its implications on economic viability. We used 12 crossbred Holstein x Zebu cows assigned to three 4 x 4 Latin Squares, in the following treatments: control (without inclusion of palm kernel cake in the diet); inclusion of 50, 100 or 150 g palm kernel cake (PKC) per kg in the total dry matter (TDM). Earnings per animal showed a reduction in values, this decrease in profitability is related to the increase in feed costs, specifically, and the costs with concentrate, which increased as the palm kernel cake was included in the treatments, 0, 50, 100 and 150 g kg-1 TDM. The effect observed for profitability affected the internal rate... |

| This study aimed to evaluate the economic viability of using different levels of oregano in diets for lactating cows fed sugar cane. We used 12 crossbred Holstein x Zebu cows assigned to three 4 x 4 Latin squares. The four treatments consisted of different levels of oregano: oregano free-control diet (0%) and diets added with 0.8, 1.6, and 2.4% oregano. Diets were formulated to meet the requirements for maintenance and milk production of 15 kg day-1. For economic analysis, we employed two economic indicators, net present value and internal rate of return. The total cost per animal and per liter of milk produced has increased with the inclusion of oregano. The inclusion of oregano was not effective for both productivity and profitability, with prices equal... |
