Resumo

O presente trabalho foi conduzido com o objetivo de avaliar o consumo e as digestibilidades aparentes de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), carboidratos totais (CHOT), carboidratos não fibrosos (CNF) e fibra em detergente neutro (FDN) em ovinos alimentados com feno de moringa (Moringa oleifera Lam) obtido com quatro idades de corte (28, 35, 42 e 49 dias). Foram utilizadas 20 fêmeas da raça Morada Nova, com 20kg de peso vivo médio, distribuídas em um delineamento inteiramente casualizado e mantidas em gaiolas de metabolismo. Observou-se efeito linear decrescente da idade de rebrota sobre o consumo de MS, estimando-se consumo máximo de 0,67 kg/dia para o feno elaborado aos 28 dias de corte. Também foi observada resposta linear decrescente, estimando-se consumos máximos de 172g/dia; 0,36kg/dia; 18g/dia, aos 35; 42 e 49 dias de idade, para PB, MO e EE, respectivamente. Para FDN, encontrou-se efeito quadrático com o avanço da maturidade da planta. As digestibilidades aparentes de MS, PB, MO e CHOT diminuíram linearmente com o avanço da idade de corte do feno de Moringa oleífera. Concluiu-se que o feno de Moringa oleífera apresentou elevado valor nutritivo até os 35 dias de corte.(AU)

The objective was to contribute to a reading of the characteristics and diversity of production systems from bovine milk in the microregion Seridó of Rio Grande do Norte, discuss the social, economic, environmental and husbandry - related primary activity of milk production. We randomly selected 28 agricultural establishments that performed the activity of dairy bovine culture with subsequent application of a structured questionnaire during September and October 2011. Data were analyzed with application of measures of descriptive analysis and determination of the index rural development (IRD) . The results showed that 53.57% of the interviewees were owners of the land, the median area of the properties amounted to 135 hectares, the median number of animals in the herd was 51 head, with minimum 11 and maximum of 350 heads establishments in the sample, 85.72% of establishments had maximum 23 cows in lactation, 100% performed manual milking with suckling calves, average productivity of 3.91 liters / cow / day, 92.86% of the interviewees did not produce silage and / or hay, 64.29% had no access to technical assistance, the average age of interviewees was 5 1 ± 10.85 years, 78.57% had only elementary education. The average of the IRD computed in the test sample amounted to 0.43 ± 0.11 on a scale 0 - 1 . The sites were grouped into 04 classes, based on your IRD. The average IRD in each dimension was 0.43, 0.55 and 0.34, respectively for economic / husbandry, social and environmental. The determination of the rate of rural development - IDR found for the sample could add establishments hierarchically. It is necessary that the inclusion of best practices in herd management, bookkeeping zootechnical, technical assistance and reorganization practices in land and environmental preservation.(AU)
