24. Evaluation of intervals between observations on estimation of eating behavior of cattle
The effect of different intervals between observations on the estimation of the eating behavior of dairy heifers and lactating cows was evaluated. Twenty Holstein-zebu crossbred dairy heifers were distributed in a completely randomized design, with four levels and five repetitions, fed isonitrogenous diets containing 71% sugar cane and 29% concentrate. Also,
