Previous issue date: 2012-04-27 === The objective was to contribute to a reading of the characteristics and
diversity of production systems from bovine milk in the microregion Serid? 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 applicat ion 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 51 ? 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 === Objetivou-se contribuir com uma leitura das caracter?sticas e diversidades dos
sistemas de produ??o de leite bovino na microrregi?o Serid? do Estado do Rio Grande do
Norte, discutir os aspectos sociais, econ?micos, zoot?cnicos e ambientais relacionados com
a atividade prim?ria da produ??o de leite. Foram selecionados, aleatoriamente, 28
estabelecimentos agropecu?rios que desempenhavam a atividade da bovinocultura leiteira
com posterior aplica??o de question?rio estruturado nos meses de setembro e outubro de
2011. Os dados foram analisados com aplica??o de medidas de an?lise descritiva e
determina??o do ?ndice de desenvolvimento rural (IDR). Os resultados demonstraram que
53,57% dos entrevistados eram propriet?rios da terra, a mediana da ?rea das propriedades
correspondeu a 135 hectares, a mediana do n?mero de animais no rebanho bovino foi de 51
cabe?as, com n?mero m?nimo de 11 e m?ximo de 350 cabe?as nos estabelecimentos da
amostra, 85,72% dos estabelecimentos tinham at? 23 vacas em lacta??o, 100% realizavam
ordenha manual com bezerro ao p?, produtividade m?dia de 3,91 litros de leite/vaca/dia,
92,86% dos entrevistados n?o produziam silagem e/ou fena??o, 64,29% n?o tinham acesso
? assist?ncia t?cnica, a idade m?dia dos entrevistados foi 51?10,85 anos de idade, 78,57%
tinham apenas ensino fundamental incompleto. A m?dia geral do IDR calculado da
amostra em an?lise correspondeu a 0,43?0,11 numa escala de 0 a 1. Os estabelecimentos
foram agrupados em 04 classes, baseando-se no seu IDR. O IDR m?dio em cada dimens?o
foi 0,43, 0,55 e 0,34, respectivamente para econ?mico/zoot?cnico, social e ambiental. A
determina??o do ?ndice de desenvolvimento rural - IDR encontrado para a amostra
conseguiu agregar os estabelecimentos hierarquicamente. Conclui-se que ? necess?ria ?
inclus?o de melhores pr?ticas de manejo do rebanho, escritura??o zoot?cnica, assist?ncia
t?cnica e reorganiza??o fundi?ria e pr?ticas de preserva??o ambiental
