The objective of this study was to evaluate the influence of lactation stage and the time interval between milking on ingredients and the production of milk goats in the semiarid region of Paraíba. We used 28 animals of Anglo Nubian breed distributed in a completely randomized design in a factorial arrangement of type 3 x 2, three stages of lactation and two milking shifts. Analysis of variance revealed no effect (P>0.05) were lactating for fat, protein and total solids. However, there was significant difference (P<0.05) for lactose and milk production within the phases of lactation and the interval between milking. For acidity and density was no effect (P<0.05), lactation stage and the milking turn. There was a negative correlation between the shift milking for milk, acidity, lactose, density, protein and fat. With respect to stage of lactation negative correlation was observed for milk and lactose positive correlation for acidity and protein. The goat milk composition is influenced by the stage of lactation and the interval between milking. Equal time interval between milking favors the production of milk with a more uniform composition.
