Description
In the transition period between the rainy and dry seasons there is decreased water, temperature and luminosity, reducing forage production and quality. Because of this variability in forage mass production, it is essential to quantify forage mass for use in planning and decision making about pastures management. The objective was to evaluate Brachiaria spp. (Syn. Urochloa spp.) cv. Mulato II (Convert HD364) growth, biomass production managed under continuous grazing with steers fed with protein supplement feed in-trough and on-ground during the seasonal transition period. The experiment was carried out in the Beef Cattle Sector of Jatai Federal University (UFJ), Brazil, from March to June 2020, in a completely randomized design, using 18 male Nellore steers at 24 months of age, with two animals per paddock. Variance analysis was performed by SAS software using the GLM procedure and time repeated measures with significance set to P < 0.05. There was no significant difference between way of supplementation. In the rainy/drought transition period, Convert-grass produced 7,622 kg DM/ha and 1,995 kg DM/ha of leaf mass. The pelleted protein supplement can be used both in-trough or with onground because the method of feeding did not change the forage offered but the canopy was undergrazed which could biased the responses to the supply method evaluated.
