Abstract
The present study aimed to evaluate the effect of rations supplementation with marine algae (MA) or/and sun flower oil (SFO) on experimental rations digestibility and nutritive values, efficiency of goats milk production, milk chemical composition and milk fatty acids profile. Twenty four lactating (Damascus x Baldi) goats at the last 6 weeks of gestation and until 16 wks. lactation period were randomly assigned into four nutritional groups (6h/ group) to receive one of the following experimental rations; R1 control (basal ration without additives); R2  (basal ration +2% Nanno chloroprssis powder (MA)); R3  (basal ration+ 2% Sun flower oil (SFO) and R4; (basal ration + 1% MA + 1% SFO). Experimental groups were offered their daily requirements ad lib.. Daily basal ration consisted of pelleted concentrate feed mix. (14% CP and 60% TDN) + Egyptian green clover (Trifolium Alexandrium). Results obtained pointed out to positive significant effects (p<0.05) of dietary supplements with MA or/and SFO on improving goats milk production in terms of fat-corrected milk FCM(kg) /h/d and milk energy value MEV kcal/kg milk, and insignificantly energy-corrected milk ECM kg/h/d, goats milk efficiency, as (kg. DMI/ kg. FCM) and as FCR (kg. milk/ kg. DMI). Dietary supplemented rations affected (p<0.05) goats milk chemical composition in compare with the dietary control group and within the dietary supplemented groups, G3 (SFO) surpassed (p<0.05) the other supplemented ones in most milk productive and milk chemical composition traits. As for milk FA's profile, results indicated that milk from goats receiving (SFO) or Nannochloropssis or their mixture (Nanno.xSFO) supplementation displayed an improvement in the FA's profile, with an increased PUFA and monounsaturated FA's contents and a decrease in SFA's content.
