| description | This experiment was carried out with the objectives of determining the daily average intake (DAI), apparent digestibility coefficient (ADC) of coast cross hay and pigeon pea nutrients and to evaluate thenitrogen balance in sheep. Ten wethers with average weight of 27.50 kg, alloted to suitable cages, were used. A completely randomized design with two treatments (T1= 80% coast cross hay + 20% pigeon peaand T2= 60% coast cross hay + 40% pigeon pea) and five replicates, was used. The treatments were evaluated under two feeding systems (voluntary and restrict). Animals receiving ration of T2 presentedhigher DAI (g/kg PV 0.75) (P<0.05) of dry matter (DM), crude protein (CB), crude fiber (CF), organic matter (OM) and nitrogen free extract (NFE), than animals receiving ration of T1. ADC of CF of the T2 were higher (P<0.05) than the ration T1. The nitrogen balance (BN) of animals that received 40% of pigeon pea (13.15g N/dia) was superior to the those receiving 20% of this leguminous (10.29g N/dia). It can be concluded that the pigeon pea can be used as protein source in the ruminant feeding, making possible ADC for DM close to 52% for animals in voluntary intake and 81% for animals in restricted intake. The increase in the percentage of pigeon pea in the sheep diets fed with Coast-cross hay can result in improvement of diet CF digestibility, as well as, in animals nitrogen balance.<p><p>O experimento foi realizado com os objetivos de determinar o consumo médio diário (CMD), o coeficiente de digestibilidade aparente (CDA) dos nutrientes do feno de capim Coast cross e feijão guandu e avaliar o balanço de nitrogênio (BN) em ovinos. Foram utilizados dez ovinos machos, castrados, com peso médio de 27,50 kg, alojados em gaiolas para metabolismo, em delineamento inteiramente casualizado com dois tratamentos (T1 = 80% de feno de Coast cross + 20% de guandu e T2 = 60% de feno de Coast cross + 40% de guandu) e cinco repetições por tratamento. Os tratamentos foram avaliados sob dois regimes alimentares (consumo voluntário e restrito). Os animais recebendo ração do T2 apresentaram maior CMD (g/kg PV0,75) (p < 0,05) de matéria seca (MS), proteína bruta (PB), fibra bruta (FB), matéria orgânica (MO) e extrato não nitrogenado (ENN), do que aqueles animais recebendo ração do T1. O CDA da FB da ração T2 foi maior (p < 0,05) do que o da ração T1. O BN dos animais que receberam 40% de guandu (13,15g N/ dia) foi superior aos daqueles que receberam 20% desta leguminosa (10,29g N/dia). Conclui-se que o feijão guandu pode ser utilizado como fonte protéica na alimentação de ruminantes, possibilitando CDA da MS próximo de 52% para animais em regime de consumo voluntário, e 81% para animais em regime de consumo restrito. O aumento na porcentagem de feijão guandu nas dietas de ovinos alimentados com feno de Coast-cross pode resultar em melhoria no CDA da FB da dieta, bem como no balanço de nitrogênio dos animais. |
