It was evaluated the ingestive behavior of lactating ewes and ewe lambs before and after weaning receiving different supplement levels (0; 0.5; 1.0, and 1.5% of body weight), grazing on a Italian ryegrass (Lolium multiflorum Lam.) pasture, under continuous variable stocking. The experimental design was completely randomized with repeated measures in time with four supplement levels and two replicates. The supplement utilized was a commercial ration, daily supplied at 2 p.m. It was evaluated the diurnal grazing time, rumination time, […]

The trial was conducted to determine the influences of grazing intensity and grazing method on morphogenetic (leaf elongation rate, leaf appearance rate, leaf lifespan) and structural (number of green leaves, length of leaves and tiller density) traits in italian ryegrass sward. The experimental treatments stemmed from a 2 x 2 factorial combination of two grazing intensities and two grazing methods (continuous and rotational). The experimental design was completely randomized block with four replications. Thirty tillers were marked per experimental unit. […]

The objective of this trial was to study the dynamics of pasture containing black oat (Avena strigosa Schreb) plus ryegrass (Lolium multiflorum Lam) on beef heifers receiving different levels of supplementation. The following treatments were used: ‘No Supplement’- animals in black oat plus ryegrass pasture; ‘Increasing’ – animals in black oat plus ryegrass pasture and fed increasing levels of supplement: 0.3; 0.6; 0.9; and 1.2 to 1.5% of body weight (BW) during the pasture cycle; ‘Fixed’ – animals in black […]

The trial was conducted to evaluate two forage availabilities (1.200 and 1.500 kg/ha of dry matter [DM]) and energy supplementation of winter pasture on herbage and animal yields. The pasture was a mixture of oat (Avena strigosa Schreb) + Italian ryegrass (Lolium multiflorum Lam). Ninety Charolais and Charolais crossbred Nellore heifers, with initial live weight of 164 kg, were submitted to the following treatments: LFA – low forage availability; HFA – high forage availability; LFAS – low forage availability + […]

The performance of beef heifers in black oat (Avena strigosa Schreb.) plus ryegrass (Lolium multiflorum Lam.) pasture was evaluated in this trial. The treatments evaluated were: ‘No Supplement’- animals in black oat plus ryegrass pasture; ‘Increasing’ – animals in black oat plus ryegrass pasture, receiving increasing levels of supplement (wheat bran): 0.3; 0.6; 0.9; 1.2 to 1.5% body weight (BW) during the pasture cycle; ‘Fixed’ – animals in black oat plus ryegrass pasture, fed 0.9% BW of supplement during all […]

The ingestive behavior of beef heifers when submitted to different energy supplementation levels was evaluated. Heifers grazing Italian ryegrass (Lolium multiflorum Lam.) and black oat (Avena strigosa Schreb) pasture, were supplemented with wheat bran, supplied daily at 2 p.m. at levels of 0; 0.5; 1.0; 1.5% of live weight. The activities of grazing, rumination, idle and trough permanence, were recorded by visual observation, at a ten minute intervals, in four periods of 24 hours. For each supplementation level were allocated […]

It was evaluated the forage production from black oat (Avena strigosa Schreb) plus italian ryegrass (Lolium multiflorum Lam) mixture under grazing with beef heifers of Charolais breed and their crosses with Nellore submitted to following treatments: 0, 0.7, and 1.4% live weight/day of supplementation of rice bran plus citrus pulp (1:1). Daily dry matter accumulation rate (TA), botanical composition, forage losses and economic return of the different levels of supplementation were evaluated. The treatments with supplementation increased TA, however, the […]

The research was conducted during the 1994/95 and 1995/96 growing seasons (Oct./Apr.), at the Estação Experimental de Ituporanga/EPAGRI – SC, with the objective to determine the potential of animal production and pasture responses as dry matter (DM) accumulation rate and quality of forage and profile structure of a pasture of `Mott’ dwarf elephantgrass (MDE) under four levels of forage on offer (FO). The actual levels of FO were 3.8 7.5; 10.2 and 14.0 kg green leaf lamina DM (GLLDM) /100 […]

This research was conducted during the 1994/95 and 1995/96 growing seasons (Oct./Apr.), at the Estação Experimental de Ituporanga/EPAGRI – SC, aiming to evaluate the pasture dynamics of `Mott’ dwarf elephantgrass (MDE) under four levels of forage on offer (FO). The actual levels of green leaf lamina dry matter (GLLDM) were 3.8; 7.5; 10.2 and 14.0 kg/100 kg LW/day, under continuous grazing, using steers of 8 to 10 mo through the put-and-take technique. A completely randomized block design with two replications […]
