Resumo: | Annual pasture species summer are used in Brazil to supply forage in in unfavorable seasons and / or to meet more demanding categories. The objective of this study was to evaluate the forage production parameters and the development of growing steers (195.0±13.40 kg, 14 ± 0.19 months), in pastures of pearl millet or forage sorghum. Treatments consisted of: Sorghum grazing (Sorghum bicolor L. Moench) and Pearl millet grazing (Pennisetum americanum Leeke). The experimental design was randomized blocks. The experimental period was 84 days, divided into three evaluation periods. Pearl millet pasture provided a greater supply of leaf blades, in relation to forage sorghum (3.64 vs. 1.98 kg DM / 100 kg body weight), but the other characteristics did not differ between forage species (P> 0.05). The evolution of weight and body structure of steers was similar between forages, as well as the animal productivity per area unit (P> 0.05). The evaluation periods significantly influenced plant and animal production (P <0.05). The advance in pasture utilization cycle resulted in worsening of the forage structure, with lower supply leaf blades in the forage canopy, a pronounced emergence spontaneous species and reduction in forage yield. There was weight and body score evolution with the advancement of grazing periods, with significant difference every 28 days (P <0.05). Sorghum or pearl millet pastures present similar productive parameters, showing good feeding options for growing steers. The advance in the productive cycle leads to modifications in the structure of the pasture, reducing the productivity per area. |

En Brasil se utilizan especies de pasturas anuales de verano para proporcionar forraje en temporadas desfavorables y/o para satisfacer categorías más exigentes. El objetivo fue evaluar los parámetros de producción de forrajes y el desarrollo de novillos (195.0 ± 13.40 kg; 14 ± 0.19 meses) en pasturas de mijo o sorgo forrajero. Los tratamientos consistieron en: pasto de sorgo (Sorghum bicolor L. Moench) y pasto de mijo (Pennisetum americanum Leeke). El diseño experimental fue de bloques al azar. El período experimental fue de 84 días, dividido en tres períodos de evaluación. La pastura de mijo proporcionó una mayor oferta de hojas (3.64 vs. 1.98 kg MS/100 kg peso vivo), pero las otras características no difirieron entre las especies forrajeras (P>0.05). La evolución del peso y estructura corporal de los novillos fue similar entre los forrajes, así como la productividad animal por unidad de área (P>0.05). Los períodos de evaluación influyeron significativamente en la producción vegetal y animal (P<0.05). El avance en el ciclo de aprovechamiento de la pastura resultó en un empeoramiento de la estructura del forraje, con menor oferta de hojas, aparición acentuada de especies espontáneas y reducción de la productividad del forraje. Hubo una evolución del peso y la condición corporal con el avance de los períodos de pastoreo, con una diferencia significativa cada 28 días (P<0.05). El sorgo forrajero y el mijo tienen parámetros de producción similares, mostrándose como buenas opciones alimenticias para novillos en crecimiento. El avance en el ciclo productivo conlleva cambios en la estructura del pasto, reduciendo la productividad por área.Espécies de pastagem anual de verão são utilizadas no Brasil para fornecer forragem em épocas desfavoráveis e/ou atender categorias mais exigentes. Objetivou-se avaliar os parâmetros produtivos da forragem e o desenvolvimento de novilhos (195,0±13,40 kg; 14±0,19 meses) em pastagens de milheto ou sorgo forrageiro. Os tratamentos consistiram em: Pastagem de sorgo (Sorghum bicolor L. Moench) e Pastagem de milheto (Pennisetum americanum Leeke). O delineamento experimental foi de blocos ao acaso. O período experimental foi de 84 dias, subdivido em três períodos de avaliação. A pastagem de milheto proporcionou maior oferta de lâminas foliares (3,64 vs. 1,98 kg MS/100 kg de peso corporal), porém as demais características não diferiram entre as espécies forrageiras (P>0,05). A evolução de peso e estrutura corporal dos novilhos foi semelhante entre as forrageiras, assim como, a produtividade animal por unidade de área (P>0,05). Os períodos de avaliação influenciaram significativamente a produção vegetal e animal (P<0,05). O avanço no ciclo de utilização das pastagens resultou em piora na estrutura da forragem, com menor oferta de lâminas foliares, surgimento acentuado de espécies espontâneas e redução na produtividade da forragem. Houve evolução de peso e escore corporal com o avanço dos períodos de pastejo, com diferença significativa a cada 28 dias (P<0,05). Sorgo forrageiro e milheto apresentam parâmetros produtivos similares, mostrando-se como boas opções alimentares para novilhos em crescimento. O avanço no ciclo produtivo acarreta modificações na estrutura da pastagem, reduzindo a produtividade por área.
