摘要

Using of Aloe vera showed as alternative feed a positive influence on the ruminant’s animals production, health and well-being. In addition, its corporation in animal feed enhanced animal performance and reproduction, as well as the nutritional quality of produced food such as meat and milk. This trial was carried out to introduce Aloe vera gel (AV gel) in dairy cows ration and determine its effects on intake, digestibility in vivo, and on quantity and quality of produced milk. The experimental animals were12 cows (mean age = 4.4 years and mean weight = 669.68 kg). They were assigned into two groups: control (C), animals were fed a basic ration and a concentrate and AV gel group (AV); the cows received the same C feed with addition of 10 g of AV gel. The dry matter intake, feed digestibility, milk yield, (feed/diet) chemical composition, and the fatty acids profile were determined. The incorporation of AV gel did not influence (P > 0.05) both feed dry matter intake and digestibility. However, the milk yield was (3.05 l/d) higher in AV lot (18.99 l/d) compared to C group (15.94 l/d) (P < 0.05). Similarly, value of protein, lactose, and fat were higher (P < 0.05) in AV group in comparison with C group. Concentration of saturated fatty acids and Omega ω − 3 and Omega ω − 6 were similar (P > 0.05) in both groups. The ω − 3 /ω − 6 ratio was lower (P < 0.05) in the AV group compared to C group (2.12 and 4.87, respectively). In addition, the concentrations of linoleic acid were (P < 0.05) greater in the AV group in comparison with C group. Use of alternative resources in cow feeding, such as Aloe vera can increase the milk product and improve the disease quality of milk specially the beneficial fatty acid and decrease the costs of animal feed.
