The Effect of Dietary Garlic (Allium Sativum), Black Cumin (Nigella Sativa) and Their Combination on Performance, Intestine Morphometry, Serum Biochemistry and Antioxidant Status of Broiler Chickens

Effects of Nigella sativa on Performance, Blood Profiles, and Antibody Titer against Newcastle Disease in Broilers

“…The results obtained during this study ( Table 5 ) on the level of serum glucose of chickens are in agreement with recent reports [ 29 , 40 ] but in disagreement with other reports [ 41 , 42 ]. Some controversial observations could be explained where the type of the extract, whole seed, and duration of consumption may exert different effects on glucose level as has been observed by Mohtashami [ 60 ] who reported that N .…”

“…sativa seeds observed during this study have also been reported by Miraghaee et al [ 24 ]. However, weekly comparison ( Table 5 ) values of total protein and albumin of the treated groups showed that differences among the groups were not significant ( p > 0.05) as previously reported [ 42 , 59 ] but in disagreement with the results observed by Singh and Kumar [ 41 ]. As shown in Table 5 , increasing of protein and albumin concentrations of the chickens fed with 0.5–2% and decreasing of those chickens fed with 4–16% N .…”

“…As shown in Figure 2 , maternal antibody titer (MDA) of the chickens against ND decreased gradually and reached the points that are considered as negative in the control group T0 (environmental contamination control) on day 21 of age, and the comparison of average antibody titers of the groups during 2 weeks of age could be explained where maternal antibody of the chick's yolk may contribute to MDA of chicks during 3 days of age, and reduction of the MDA starts on day 4 of age based on half-life time (4-5 days) in case of ND [ 42 ]. On the contrary, antibody titers of ND of the vaccinated chickens (group T1–T7) were increased after vaccination at the 14th day of the experiment.…”

“…In general, biochemical parameters of poultry may be influenced by various factors and the results of this study on biochemical parameters ( Table 5 ) were compared with reported reference ranges [ 40 – 42 , 56 – 58 ].…”

“…sativa as a multipurpose feed additive on performance, blood profiles, and humoral immune responses in broiler chickens. To the best of our knowledge, the closest reports to our study in the literature are works of Al-Beitawi et al [ 29 ], Durrani et al [ 36 ], Shewita and Taha [ 37 ], Ghasemi et al [ 38 ], Hossain et al [ 39 ], Shirzadegan et al [ 40 ], Singh and Kumar [ 41 ], and Aydogan et al [ 42 ], and the present study has a lot of differences with them including the use of various percentages of N . sativa seeds in diets and weekly measurement of performance, immune responses, serum biochemical parameters, hemogram, and leukogram indices.…”
