The weight gain recipe outperformed the sixth treatment for all weeks, and in the food conversion treatment T1 decreased in the first week, while in the second week it decreased in T5, while in the third and fifth weeks, and the total rate decreased T6, T5, but in the sixth week it was lower in T6.
