Abstract
ABSTRACT This study aimed to evaluate the buriti oil (Mauritia flexuosa L.) inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter) replacing ground corn on the feeding behavior, as well as physiological and hematological variables of crossbred lactating Anglo Nubian goats. Eight Anglo Nubian goats were used, which were distributed in a double 4 × 4 Latin square experimental design (four periods and four levels of buriti oil) replacing corn in the total dry matter. For the [...]

This study aimed to evaluate the buriti oil (Mauritia flexuosa L.) inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter) replacing ground corn on the feeding behavior, as well as physiological and hematological variables of crossbred lactating Anglo Nubian goats
The diets were formulated according to NRC (2007) recommendations to meet the nutritional requirements of lactating goats with production of 1.5 kg milk/goat/day, corrected for 4% fat
Summary
Vegetable oil is considered as a source of unsaturated fats in diets for ruminants. It can influence the microbial metabolism in the rumen and, the feeding behavior of ruminants (Lima et al, 2015). Supplementation of vegetable oils in ruminant diets must not exceed 70 g kg−1 of total DM. Inclusion of more than 70 g kg−1 of oil can interfere in ruminal fermentation and, lead to a reduction in the digestibility of nutrients, especially fiber (Lima et al, 2015). Energy supplements with the base oils can reduce the feed costs, but it is essential to maintain the balance of energy and protein in the rumen (Costa et al, 2016). Balanced diets can promote an increase in feed efficiency and milk production
