The aim of the study was to evaluate the economic viability of termination of super-young
dairy cattle slaughtered at 6 months of age and fed diets containing different levels of addition
of crude glycerin replacing corn. 24 calves were used three months of age and initial weight of
95.46 ± 11.80 kg, distributed in experimental design with four experimental diets with
inclusion levels (0, 80, 160 or 240 g / kg) of crude glycerin in the dry matter of the total diet
and six replicates per treatment. The experimental period was 104 days, 14 days for the
period of adaptation and 90 days for completion of the performance test. It was found that the
fixed cost and the opportunity cost of land linearly reduced as crude glycerin was included in
the diets. The variable cost components have not changed significantly by the inclusion of
crude glycerin in the diet. Fixed costs expressed as a percentage only the opportunity cost of
land reduced linearly, the other variables that make up the fixed costs were not influenced by
the inclusion of crude glycerin. The cost of acquisition of animals in percentage increased
linearly. The cost of food has reduced linearly. There was no significant difference for any of
the financial return indicators analyzed. The male calf milk mixed use is feasible because it
has economic returns when used in the containment system. The use of crude glycerin
replacing corn in diets for the production of super-young males of dairy calves at a price of
60% of the market value of corn showed no economic advantages in the activity to justify their
independent use of the level of inclusion. |
