The effects of feeding different calcium levels and limestone particle sizes on body and morphometric development of the digestive tract in replacement pullets were evaluated in this trial. One thousand and four hundred Lohmann LSL replacement pullets were assigned to a complete randomized design with a 5 x 2 factorial (calcium levels and limestone particle size) and five replicates of 28 and 18 birds/plot, respectively, for the periods from 3 to 7 and from 8 to 12 weeks old. The […]

This work aimed to evaluate body measures of colts and fillies of Mangalarga Marchador breed with principal components analysis. Measures were performed at birth week, in 55 colts and 41 fillies; at six months of age, in 35 colts and 37 fillies; and at twelve months of age, in 19 colts and 31 fillies. There were made 25 linear measures, including height, length, width and girth, and 11 angular measures. Evaluation of animals with 12 months of age was made […]
