This experiment was conducted to investigate the effect of the protected fat supplement of unsaturated fatty acids in dairy camels. Twenty-eight Arab camels were fed with control diet and diets containing linolenic acid (omega-3). The obtained results were analysed as a completely randomized design. Milk production, fat, protein and the antioxidant activity of raw milk increased by using protected fat, but ash, solids and density decreased (p < 0.05). Fat, protein, density and the antioxidant activity of fermented milk of camels increased, but solids and lactose decreased (p < 0.05). The total microbial load and population of moulds in raw and fermented milk of camels fed with protected fat decreased (p < 0.05), but the population of Lactobacillus increased (p < 0.05). The concentration of unsaturated fatty acids C18:1, C18:2 and C18:3 and conjugated linoleic acid (CLA) increased (p < 0.05). Therefore, it may be possible to use omega-3 protected fat supplementation of 80 g per day in dairy camels feeding in the desert.
本实验旨在研究在奶用骆驼中添加不饱和脂肪酸保护脂肪的效果。28头阿拉伯骆驼分别饲喂对照日粮和含亚麻酸（ω-3）的日粮。所得结果采用完全随机设计进行分析。使用保护脂肪后，原奶的产奶量、脂肪、蛋白质和抗氧化活性增加，但灰分、固形物和密度降低（p<0.05）。骆驼发酵乳的脂肪、蛋白质、密度和抗氧化活性增加，但固形物和乳糖降低（p<0.05）。饲喂保护脂肪的骆驼原奶和发酵乳中的总微生物负荷及霉菌数量减少（p<0.05），但乳酸菌数量增加（p<0.05）。不饱和脂肪酸C18:1、C18:2和C18:3以及共轭亚油酸（CLA）的浓度增加（p<0.05）。因此，在沙漠地区奶用骆驼的饲养中，每天添加80克ω-3保护脂肪可能是可行的。
