“…Grouping of farms according milk production and herd size (Smith et al, 2002) or by nutritional and sanitary characteristics of the milk (Bodenmüller Filho et al, 2010) was seen. In practice, the differentiation of producers according to milk yield is still the key factor for the characterization of the production unit and is often carried out by the dairy industry (Bueno et al, 2004;Wagner et al, 2004;Fassio et al, 2006;Manzano et al, 2006). However, discriminant analysis showed out the role of feeding strategies in differentiating dairy farms which is consistent with Fernandes et al (2004) studying the same region, where those authors highlighted the lack of expertise of producers, inefficient feeding strategies and low productivity of dairy cows.…”

In the tropics, milk production systems present high diversity and distinct ability to adapt to the demands of consumers and market conditions. Knowledge of the factors that affect the quality of milk and agglomerate of production systems into fewer groups can facilitate analysis and the decisions needed to improve them. The objective of this paper was to characterize, classify and analyze dairy production systems in the Brazilian southern region, and relate their productive aspects to the physical-chemical attributes of the milk produced. A multivariate analysis was conducted with 26 indicators obtained from a survey covering 328 dairy farms. Variance was fully explained by the first three principal factors. The first factor included feeding strategies, the second included the farm's structure traits and the third included milk composition. Canonical analysis revealed distribution of farmers into three clusters. All feeding strategies, except salt supplementation, as well as monthly milk production, herd size, number of lactating cows in farm and unstable milk frequency were important discriminant variables to determinate cluster formation. The clusters were differentiated by feeding strategies used and the high standard deviation in some of these strategies demonstrated the adoption of specific strategies in different seasons. Cluster 3 had the largest monthly milk production and larger number of lactating cows, but the productivity of cows in the different clusters was not significantly different. The lower unstable milk frequency in cluster 3 is associated with more intensive use of silage, mineral-vitamin premix and commercial concentrate in the diet of animals. The physical-chemical composition of milk and the somatic cell count did not differ between clusters.

“…Os resultados encontrados de Produção de leite por dia (Tabela 4) para os produtores da região Nordeste foi a menor média em relação as outras regiões brasileiras (máximo de 7,29 Litros por dia e mínimo de 6,79 L por dia por vaca). Resultado este, inferior ao encontrado por Neves et al (2011), que relataram produção média de 9,3 Litros por dia por vaca e por Manzano et al (2006), Oliveira et al (2007), a relação de vacas em lactação pelo total de vacas do rebanho, sofre a influência dos índices zootécnicos, período de lactação e intervalo de partos. Desse modo, como as vacas em lactação são as que produzem as duas principais fontes de receita da fazendaleite e animais -maior relação de vaca em lactação dentro da propriedade rural significará maior proporção de matrizes na obtenção e participação da receita no rebanho.…”
