ABSTRACT.
This work studies the effects of forestation on forage mass and its chemical composition, as well as mean air temperature and their impact on beef cattle performance and grazing behaviour when compared to a natural grassland system. The systems comprised 100% natural grassland from the Campos biome (NG) and forested land (FL) 60% 6 y.o. Pinus taeda (500 trees per hectare) and 40% of natural grassland. We found that the crude protein composition of the pasture growing under the trees was higher, while mean air temperature was lower during the hot season. This changed the grazing pattern of the cattle, and was associated with higher average daily gain of the animals grazing in FL. We conclude that the introduction of trees in natural grasslands changed the environmental conditions, providing a better thermic and nutritive situation for growing grazing cattle that ultimately results in an increase in their productivity. © 2018, Springer Nature B.V. |

Timely grazing decision-making requires routine information on the herbage mass (HM) and pasture growth rate (GR). The aim of this study was to compare the correspondence, cost, and reliability of two indirect methods -the comparative yield method (COMPYLD) and the pasture-meter (CDAX)- to estimate HM and weekly GR of a 42 ha grazing area. Weekly assessments from Apr 2017 to Oct 2018 were made with both methods to estimate HM and GR of 13 individual paddocks. In addition, estimated GR were compared to aerial net primary productivity (ANPP) estimated using remote sensing (SAT). Estimated HM was 22% lower for COMPYLD than CDAX (HMCOMPYLD=33+0.78*HMCDAX, R2=0.61, CV=17%, RMSE=291 kgDM/ha). The correspondence between methods of estimated weekly GR of individual paddocks was weak (GRCDAX=0.18*GRCOMPYLD+19.1, R2=0.05, CV=73%, RMSE=21.8 kgDM/ha/d). However, when integrated in three-week moving-averages, over the complete grazing area, COMPYLD and CDAX yielded similar GR up to 35 kg DM/ha/d. Accumulating GR of the grazing area over one year resulted similar to annual SAT-estimated ANPP. These results imply that, on one hand, decisions based on nominal HM, such as target HM and grazing strip size, would need to be adjusted depending on the method, but on the other hand, decisions based in temporal trends or GR, such as size and timing of setaside areas for reserves, would be unaffected by method. Compared with COMPYLD, CDAX would be advantageous whenever high labour costs offset higher amortization, maintenance and fuel costs, provided there is an alternative in place to monitor during downtime periods. © 2023 Cambridge University Press.
