Description
During the transition period between rainy and dry season, unfavorable climatic conditions such as limited water availability, temperature and light limit forage production and quality. Because of the seasonal pattern, it is essential to quantify forage mass for pasture management and planning purposes. The objective of this study was to evaluate Paiaguas herbage mass in pasture managed under continuous stocking with steers supplemented with protein concentrate offered in feed bunk and onground. The experiment was carried out in the Beef Cattle Facilities of Jatai Federal University (UFJ), from March to June 2020, in a completely randomized design, using 18 male Nellore steers at 24 months of age, with three animals per paddock or 2 AU/ha in six paddocks, and the treatments were supplementation with protein concentrate offered in feed bunk and on-ground. Variance analysis was performed with software SAS following the GLM procedure using Mauchly's sphericity test to validate a repeated measures analysis of variance (ANOVA). When Mauchly's Test was significant Multivariate Test was used (Wilk's Lambda) to compare treatments and when Mauchly's Test wasn't significant Univariate Test was used. There was no significant difference for herbage mass between supplementation offered in feed bunk and on-ground. In the rainy/dry transition period, from March to June, Paiaguas produced 6,137 kg DM/ha.month-1 and 1,292 kg DM/ha.month-1 of leaf mass. The pelleted protein supplement can be used both feed bunk or on-ground because the method of supply doesn't change the herbage production and structure but the canopy was under-grazed which could biased the responses to the supply method evaluated.
