| Abstract | ||||
| This study aimed to investigate the effect of treated sunflower meal with 2% condensed tannins (Quebracho tannins, QT; Unitan, Argentina) or/and Chamomile Flowers supplementation on productive performance of Zaraibi dairy goats and their offspring. A feeding trial was conducted using twenty pregnant goats at the 3rd and 4th parities and initial body weight 35.55 ± 0.62 kg at the last month before parturition and lasted for 90 days after parturition. Animals were divided into four similar groups (n=5does/each) using the randomized complete block design. Goats were fed concentrate feed mixture (CFM) to cover 50% of their requirements according to NRC (1985) for goats and rice straw (RS) was given by 150 g/head/day; while berseem was given at ad-libitum. Group G1 (control) received CFM contained untreated sunflower meal, while group G2 fed CFM contained untreated sunflower meal and supplemented with 0.25% Chamomile Flowers (Ch-F) and G3 fed CFM contained treated sunflower meal with 2% tannin (Quebracho) and G4 fed CFM contained treated sunflower meal with 2% tannin (Quebracho) and supplemented with 0.25% (Ch-F) on DM basis. Results indicated that digestibility of most nutrients and feeding values were significantly higher (P<0.05) with G2 than those of other groups. While, digestibility of CP was significantly higher (P<0.05) for all tested groups than that of control one. Ruminal ammonia-N and total volatile fatty acids concentrations were lower significantly (P<0.05) in G3 and G4 than G1 and G2. Daily milk yield was significantly (P<0.05) higher with G4 over the whole experimental period than that of control and insignificant higher than the other tested rations . Meantime, the improvement in 4% fat corrected milk yield being 124, 110 and 103% for G4, G3 and G2 compared to that of G1 over the whole experimental period. Milk constituent contents did not significantly affected by dietary treatments despite there were slightly increases in milk constituents with G4 ration in comparison with the other treatments. Also, feed conversion as kg DMI, TDNI or DCPI per kg milk improved for G4 in comparison of other groups. Economic efficiency of G4 recorded the best one among the experimental treatments and increased by 21.18% based on control ration (G1). Also, G4 revealed significant (P<0.05) positive effect on final weight, total and daily weight gains for kids during suckling period. No deleterious effects on liver, kidney functions and general health of animals fed the manipulated rations. It could be concluded that the protection process of sunflower meal with 2% QT and supplemented with 0.25% Chamomile Flower (G4) was more beneficially effective on Zaraibi dairy goats performance and economic efficiency. | ||||
