Resumo: | This study aimed to assess the effect of sorghum planting patterns on forage response and performance of beef heifers at finishing phase. The experimental period lasted 84 days; treatments consisted of the combination of two interrow spacings (22 and 44 cm) and two sorghum-sowing rates (12 and 24 kg ha?1). Beef heifers, at finishing phase, with initial age of 15 months (± 2.3 months) and average body weight of 262 kg (± 37.95 kg), continuously grazed forage. The experimental design was completely randomized in a 2 × 2 factorial scheme with three repetitions per area. The different planting patterns did not affect (P > 0.05) dry matter production (5,447.78 kg DM ha?1) and accumulation rate (58.47 kg DM ha?1 day?1). Forage accumulation rate, leaf mass, forage mass, leaf supply and forage supply were influenced (P < 0.05) by time. Similar behavior was observed for stocking rate, weight gain per area unit and daily weight gain, with values of 1,172.32 kg of liveweight ha?1, 312.31 kg ha?1; 0.891 kg day?1, respectively. Animal performance had no effect (P > 0.05) from planting patterns, with nearly 4.04 mm of subcutaneous fat thickness and final weight of 330.36 kg. Animal body development showed no significant differences (P > 0.05), with values for length, heart girth and hip height of 132.01, 163.75 and 126.75 cm, respectively. The weight to average height ratio between planting patterns was 2.67 kg cm?1. |

O período experimental teve duração 84 dias. Os tratamentos consistiram na combinação de dois espaçamentos entrelinhas (22 e 44 cm) e duas taxas de semeadura do sorgo (12 e 24 kg ha-1). Para o pastejo das forragens produzidas, foram utilizadas novilhas de corte, em fase de terminação, com idade média inicial de 15 meses (± 2,3 meses) e peso corporal médio de 262 kg (± 37,95 kg). O método de pastoreio foi contínuo. O delineamento experimental utilizado foi o inteiramente casualizado com três repetições por área, em esquema fatorial 2 x 2. Os diferentes padrões de plantio não influenciaram (P > 0,05) na produção de matéria seca (5 447,78 kg de MS ha-1) e na taxa de acúmulo de matéria seca (58,47 kg de MS ha-1dia-1). As variáveis taxa de acúmulo de forragem, massa de lâminas foliares, massa de forragem, oferta de lâminas foliares e oferta de forragem foram influenciados (P < 0,05) pelo avanço do período de utilização. Comportamentos similares foram observados para as variáveis: carga animal, ganho de peso por área e ganho de peso diário, com valores de 1172,32 kg de peso vivo ha-1; 312,31 kg ha-1; 0,891 kg dia-1, respectivamente. O desempenho animal não foi influenciado (P > 0,05) pelos padrões de plantio do sorgo, obtendo-se, em média, 4,04 mm de espessura de gordura subcutânea e peso final de 330,36 kg. O desenvolvimento corporal dos animais não apresentou diferenças significativas (P > 0,05), com valores para comprimento, perímetro torácico, e altura de garupa de 132,01; 163,75; 126,75 cm, respectivamente. A relação peso: altura média entre os padrões de plantio foi de 2,67 kg cm-1.UEL2017-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo de Pesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2650810.5433/1679-0359.2017v38n3p1537Semina: Ciências Agrárias; Vol. 38 No. 3 (2017); 1537-1550Semina: Ciências Agrárias; v. 38 n. 3 (2017); 1537-15501679-03591676-546Xreponame:Semina.
