COMPORTAMENTO INGESTIVO DE NOVILHAS LEITEIRAS EM CRESCIMENTO SOB DOIS TIPOS DE SUPLEMENTAÇÃO MINERAL

Abstract

The objective of assessing the behavior ingestivo (grazing time, time of rumination, time spent with offset, leisure and water consumption) of 16 Dutch heifers x Zebu in pastoroated with Brachiaria brizantha CV. Marandú, divided into two treatments. 1 treatment consisted of heifers supplemented with mineral salt and 2 treatment were supplemented with mineral salt protein bagel. The experimental area of 1 ha, was divided into 28 irrigated pickets being 2 groups of 14 pickets for each treatment, with 2 days of occupation and 26, as well as the area containing aguada, salt and natural shading. A total of 8 observations were carried out with 10:0, starting at 07:00 hours 17:00 hours. It was held four observations on the first day of grazing and 4 on the second day. The average daily temperature in the days of observations was to 27oC and relative humidity between 60 and 70%. No statistical differences were found for the variables comportame between the two treatments (P 0.05 >) and between the first and second day of grazing (P > 0.05). The animals stayed most of the day, whichever is pastejando this activity in the morning and late afternoon, already 12 times at 3:0 pm were divided between idleness and rumination. The time spent on leisure and rumination on shading area occurred at the time the hottest day. The displacement and water consumption was very low, due to the mild climate and the largest relationship foil/culm grassland.
