Última Effect of Two Strains of Probiotics on the Antioxidant Capacity, Oxidative Stress, and Immune Responses of Salmonella-Challenged Broilers Rev. Bras. Ciênc. Avic. Abudabos,AM; Alyemni,AH; Zakaria,HAH. Abstract The present study aimed at evaluating the effect of two strains of probiotics (Bacillus subtilis PB6 and Bacillus Cereus var. toyoi) on selected indicators of the antioxidant status and immune responses of broilers before and after challenge with Salmonella enterica subsp. Typhimurium (S. typhimurium). Birds were distributed into the following five treatments: negative control (CTL−); negative control+S. typhimurium (CTL+); antibiotic+S. typhimurium, (AB); Toyocerin(r)+S. typhimurium (TOYO); and CloSTATTM+ S. typhimurium (CLOS). Birds in all treatments, except for CTL−, were orally challenged with 3 x109 CFUS. typhimurium at 16 days of age. The results showed that total antioxidant capacity (TAC), superoxide dismutase activity (SOD), and hydrogen...

Bras. Ciênc. Avic. Abudabos,AM; Aljumaah,RS; Algawaan,AS; Al-Sornokh,H; Al-Atiyat,RM. ABSTRACT In total, 806 eggs of free-range Hassawi indigenous chickens were collected from local farm in Saudi Arabia. Eggs were weekly collected for 11 weeks. Initial egg weight (IEW) was recorded, and eggs were graded into four classes (A: 35-40 g, B: 40-45 g, C: 45-50 g, and D: 50-55 g). Eggs were stored for seven days at 75-80% relative humidity and 14-16 C, after which egg weight losses (WL0) were calculated. During incubation, eggs were weighed on days 7 (W7) and 14 (W14), and egg weight losses on days 7 (WL7) and 14 (WL14), and total loss (WL0-14) were calculated. Hatchling weight (CW) was measured. The proportion of CW relative to egg weight loss (WL) on days0, 7 and 14 days of incubation (CW:WL0; CW:WL7 and CW:WL14, respectively), and break out...

Bras. Ciênc. Avic. Murshed,MA; Abudabos,AM. ABSTRACT A total of 350-one-day old chicks were placed in 70 cages, with 14 cages per treatment. The following five treatment diets were fed for 14 days: T1 = non-supplemented, control diet (CONT); T2 = diet with antimicrobial growth promoter (AGP); T3 = diet with a probiotic (PROB); T4 = diet with a prebiotic(PREB), and T5 = diet with the probiotic and the prebiotic (SYM). The growth experiment was carried out from 1 to 14 days of age. Feed and water were provided ad libitum and birds were maintained at 24-h light schedule. Diets were formulated to contain 3000 kcalME/kg and 21.5% crude protein, and the test materials were added on top. The cumulative results of1 to 14 days of age revealed that broiler fed the AGP and PREB diets presented the highest BWG...

Ciênc. Avic. Qaid,M; Albatshan,H; Shafey,T; Hussein,E; Abudabos,AM. ABSTRACT The current experiment was conducted to evaluate the effect of stocking density (SD) on the performance and immunity of 1- to 14-d-old broilers. A total of 1836 one-day-old Cobb 500 broilers were housed at four different SD (30, 60, 90 and 120 chicks/m2). Body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) were estimated on d 2, 5, 8, 11 and 14. Relative lymphoid organ weights, maternal antibody titers against IBV, IBD and NDV, and stress indicators were estimated on d 3, 6, 9 and 12.The results indicated that age significantly (p<0.001) affected the performance and immunity of broiler chicks. Stocking density significantly (p<0.001) affected the performance and physiological stress indicators of broiler chicks, but not...
