Improvement of Milk Composition and Properties of Labneh Using Oil Seeds as Supplement for Lactating Zaraibi Goat Rations

Ibrahim A.A. Abou Ayana and H.M. El-Shabrawy
Investigating dairy goat feeding is a good way to increase milk yield and improve milk composition and dairy products. Thirty five lactating Zaraibi goats were divided into five groups; seven in each, besides control, two levels of canola seeds 5 and 10% and two levels of sunflower seeds 7 and 14% were used instead of 5, 10, 7 and 14% of concentrated feed for group 2, 3, 4 and 5, respectively. Ruminal individual Volatile Fatty Acids (VFA's), some blood constituents (Urea-N, Total protein, Albumin and Globulin) of lactating goats moreover, milk production, major components of milk and Fatty Acid (FA) profile were determined. Milks resulting from these treatments were manufactured Labneh. Significantly (p<0.05), VFA's, acetic acid and the ratio of acetate to propionate increased, but NH3-N, propionic acid and butyric acid decreased for goats fed canola or sunflower diets than the control. A significant difference was noticed among treatments in blood total protein. All treatments improved the milk yield, 4% fat corrected milk (4% FCM). The most of saturated fatty acids reduced while unsaturated and Conjugated C18:2 increased. High Sunflower Seeds (HSFS) treatment was the greatest sensory evaluation with redacting of "goaty odour" in other treatments except the control.
