Resumo: | Mature Paspalum dilatatum hay was baled untreated, or sprayed with a solution supplying 12 g N and 1,2 g S/kg forage, as urea and NaHSO4, respectively, with and without the addition of caustic soda (40 g NaOH/kg forage). Sprayed forage was left in a moist condition in windrows for 24 hours before tedding and baling. Forages were chopped into 5-10 cm length and offered ad lib. to 40 Hereford streers and heifers housed in individual stalls and allocated to five treatments as follows: A) untreated hay; B) N + S; C) N + S + 300 g meat meal/head/day; D) N + S plus sodium hydroxide; E) N + S plus sodium hydroxide plus 300 g meat meal/head/day. Animals on treatment A suffered muscular trembling and ataxia and were removed from the trial. Liveweights were recorded twice weekly over 44 days and liveweight changes calculated as the coefficients of liveweight regressed against time. Liveweight gains did not differ significantly, being 471, 474, 547 and 525 g/head/day on treatments B, C, D and E, respectively. Voluntary dry matter intakes were higher on treatments D and E than on treatments B and C (D, E > B, C; P<0,05), being 4,18; 3,93, 3,62 and 3,73 kg/head/day, respectively. The in vivo digestibility of organic matter in the dry matter was similar on all treatments (52%). |

The in vivo digestibility of organic matter in the dry matter was similar on all treatments (52%).Feno de Paspalum dilatatum maduro foi enfardado sem tratamento ou pulverizado com uma solução suprindo 12 g de N (como uréia) e 1,2 g de S (como NaHSO4)/kg de forragem com ou sem a adição de soda cáustica (40 g de NaOH/kg forragem). A forragem pulverizada foi deixada em condições úmidas em leiras por 24 horas, antes de ser revirada e enfardada. As forragens foram cortadas em pedaços de 5 a 10 cm e oferecidas ad lib. para 40 novilhos e novilhas da raça Hereford, alocados em baias individuais e distribuídas casualmente em cinco tratamentos, como seguem: A) feno não tratado; B) N + S; C) N + S + 300 g de farinha de carne/cab/dia; D) N + S + soda cáustica; E) N + S + soda cáustica + 300 g de farinha de carne/cab/dia. Os animais do tratamento A sofreram tremores musculares e ataxia e foram removidos do experimento. As pesagens foram feitas duas vezes por semana durante um período de 44 dias, e as variações no peso vivo foram calculadas como coeficiente da regressão do peso vivo com o tempo. Os ganhos de peso não foram significantemente diferentes entre, tratamentos, sendo 471, 474, 547 e 524 g/cab/dia nos tratamentos B, C, D e E, respectivamente. Os consumos voluntários da matéria seca foram maiores nos tratamentos D e E do que nos tratamentos B e C (D, E > B, C; P < 0,05), sendo 4,18; 3,93; 3,62 e 3,73 kg/cab/dia, respectivamente.
