slugInfluence of lactation stage and interval between milkings on the milk composition and production of goats in the semi-arid
Journal Title: Journal of Animal Behaviour and Biometeorology - Year 2015, Vol 3, Issue 2
Abstract
The objective of this research was evaluating the influence of lactation stage and the time interval between milkings on milk ingredients and the production of goats in the semi-arid region of Paraiba. It was used 28 animals of Anglo Nubian breed distributed in a completely randomized design in a factorial arrangement of type 3 x 2, three lactation stages 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 lactation phases and interval between milkings. For acidity and density, there was no effect (P>0.05) from lactating, but significant effect (P<0.05) from the milking turn. There was negative correlation between the shift milking for milk production, acidity, lactose, density, protein and fat. With respect to lactation stage negative correlation was observed for milk production and lactose and positive correlation for acidity and protein. The goat milk composition is influenced by the lactation stage and the interval between milkings. Equal time interval between milkings favors the milk production with a more uniform composition.
