Abstract :
The effects of two levels of cotton seed and sunflower oil supplemented to the concentrate
fed to Moxotó milking goats on the physicochemical and sensory characteristics of milk
were studied. Treatments consisted of a control group without oil (control), 3% cotton seed
oil added to the dry matter, 5% cotton seed oil, 3% sunflower oil and 5% sunflower oil. The
supplementation with both vegetable oils increased (P < 0.05) the fat content and dry matter
of milk. However, such increase was higher (P < 0.05) in milk from goats supplemented
with cotton seed oil compared to sunflower oil. Lactose contents were higher (P < 0.05) in
milk from goats receiving oil-supplemented diets. Considering the sensory analysis, the
treatment with cotton oil 5% led to stronger (P < 0.05) sensory attributes of odour and goatish
odour in milk, leading to less acceptability of the milk. In conclusion, the addition of
vegetable oil, in particular from cotton seed, to the diet of crossbred goats increased the fat
content and strengthened the goatish flavour of milk
