TLDR
The SL did not affect the pasture regrowth vigor, because of the maintenance of biomass components in accepted levels and it was observed a squared effect of SL on the MSLVres and IAFres.Abstract:
This research evaluated the canopy structure of tanzania grass under intermittent stocking with four concentrate supplementation levels (SL) (0.0; 0.6; 1.2 and, 1.8% of live weight), in a split plot design, with SL being plots and grazing cycles (GC) subplots, with four replicates. Total herbage dry mass (MSFT), death herbage dry mass (MSFM), green herbage dry mass (MSFV), green leaf blade dry mass (MSLV), green stem dry mass (MSCV), canopy height (ALT); number of live leaf per tiller (F/P), leaf/stem (F/C) and live/death material (MV/MM) ratios, pre- and post-grazing, as well as the tiller populational density (DPP) pre-grazing and residual leaf area index (IAFres) were determined. Considering pre-grazing biomass components, it was not observed significative effects between SL and GC to F/P, MSFM, MSFV, MV/MM, MSLV and, MSCV. For canopy height, it was observed difference between cycle 4 compared to others. The MSFT was affected by SL, where the sheeps supplemented with 0.6% LW was similar to the ones supplemented with 0.0 and 1.8% LW levels, however at the 0.6% LW level, MSFT was greater than 1.2% LW. There were no effects of SL and cycles on MSFTres and MSFMres. It was not observed differences among 0.0, 0.6 and 1.8% SL on MSFTres and MSFMres, however the 0.6% SL (LW) was greater than 1.2% SL (LW). There was a squared effect of SL on MSFVres, however, there was no observed effect of cycles. It was not observed effect of SL and GC on the MV/MMres relation. It was observed a squared effect of SL on the MSLVres and IAFres. There was a squared effect of SL on the MSCVres. The addition of SL caused increase in F/Cres. It was not observed effect of SL on DPP. The SL did not affect the pasture regrowth vigor, because of the maintenance of biomass components in accepted levels.read more

TL;DR: Residual TPD showed interaction among factors with tillering reduction in the frequencies 85 and 95% of the IPAR of 1.8, and for tiller population density (TPD) and the number of leaves/tiller, an interactionamong factors occured, reducing their values on pastures managed with residual leaf area index of1.8.

Effect of intensity of defoliation on regrowth of pasture
TL;DR: A pasture association comprising short-rotation ryegrass, red clover, and white clover was subjected to three different intensities of defoliation by cutting down to 1, 3, and 5 in, and efficiency was initially lower following severe defoliated than following less severe treatment.
