Abstract


Moringa oleifera (MO) is a rich source for antioxidants and a promising feed for livestock. The MO plant is reputed for its adaptability to grow in all types of soils and to tolerate hot and dry conditions. Moreover, it has a high crude protein (CP) content, significant amounts of vitamins A, B, and C in the foliage and high amounts of polyphenols, resulting in a significant anti-oxidative activity Moringa leaves can be stored for long periods without deterioration in nutritive value.
In the current research, we aimed to evaluate the effect of ensiled MO, included as a supplement in the diet of ruminants on: (i) Feed efficiency and digestibility as well as milk yield, composition and health promoting traits, in lactating Holstein cows. (ii) Growth and efficiency parameters, and meat quality traits of growing Assaf lambs (iii) Milk yield, composition and health promoting traits and urea content in milk of lactating goats.
In the first year of the study we examined the effects of feeding a new variety of MO ensiled in a mixture with wheat hay and molasses, at a ratio on DM basis of 370 : 540 : 90 g/kg, respectively, as substitute for wheat silage and hay in dairy cow ration. The nutritional effect was studied on intake, digestibility, milk yield, milk composition, milk production efficiency, and milk anti-oxidative activity. Yields of milk, FCM and ECM were significantly higher in cows fed MO silage compared to the control cows. Milk of the Moringa-fed cows was characterized by 20% more anti-oxidative activity. However, this dose of ensiled MO supplement impaired DM, and NDF digestibility of the cows, compared with the control group. Based on the findings findings, we suggested to ensile mixture of MO with soy hulls or corn grains as higher digestible additive for lactating dairy cows.
In the second year, we aimed to explore whether dietary supplementation of Moringa silage to Assaf lambs, would affect their feed efficiency, growth rate and meat quality variables, with emphasis on meat tenderness. Steaks of Moringa-fed lambs were tenderer than the controls, by means of shear-force (SF), and characterized by longer sarcomeres and lower intra-muscular fat (IMF) content. No difference was revealed between groups in collagen content (CC). In terms of production efficiency, supplementation of ensiled Moringa oleifera in the diet did not affect the final body
weight but increased the BWG and feed efficiency utilization of the moringa-fed group. Based on the described above, we suggested that Moringa oleifera based dietary manipulation could be implemented in order to design a tender and lean lamb meat.
In the third year of the study, we examined the effects of feeding ensiled MO in a mixture with wheat hay and molasses on milk yield, milk composition, and anti-oxidant capacity of lactating goats. Anti-oxidant capacity was found to be significantly higher in milk of goats supplemented with moringa silage in their diet. Respectively, somatic cell count was the lowest in the milk of moringa-fed goats.
In conclusion, using MO as a supplement in the diet of ruminants, improved production efficiency parameters as well as milk and meat quality phenotypes, providing both milk and meat with improved anti-oxidant capacity.
