MANCIO, Antonio Bento et al. Effects of feeding different liquid diets with or without growth promoter on performance of kid goats. R. Bras. Zootec. [online]. 2005, vol.34, n.4, pp. 1305-1313. ISSN 1806-9290. http://dx.doi.org/10.1590/S1516-35982005000400027.
The objective of this experiment was to study the effects of feeding whole goat milk or fermented cow colostrum supplemented or not with soy oil and with or without the growth promoter Zeranol on performance of kid goats. Twenty-four Alpine kid goats assigned to a completely randomized design in a 3 x 2 factorial arrangement were used in this trial. The following variables were investigated: weight gain, intakes of dry matter and concentrate, feed conversion, and organ sizes. Significant differences were observed among liquid diets with or without Zeranol for weight gain at 29, 36, and 50 days old, but not for the average daily gain. No significant differences for intake of both dry matter and concentrate as well as for feed conversion were detected among liquid diets. Supplementation of the liquid diets with soy oil and injection of Zeranol did not change the organ sizes.
