Vaccines derived from the lentogenic and mesogenic strains are used for the protection of clinical ND in chickens. No information is available on the protection offered by these vaccines against virus replication and shedding in Nigeria. This study compared the abilities of La Sota and Komarov vaccines to protect chickens against replication and shedding in chickens challenged with the velogeni...

Forty randomly selected chickens were allocated into four groups: K, HA, Cd and Cd + HA. After a 5-day adaptation period, the experiment was initiated. Group K was fed a diet without supplements. Group HA was fed the same diet with a 0.5 g supplement of humic acid per chicken/day. Group Cd was treated with 0.147 mg Cd per chicken/day (0.3 mg of CdCl2·2.5H2O), and Group Cd + HA was given the sam...

The objective of this study was to evaluate whether the addition enzymes phytase and xylanase, isolated or associated, in liquid form after feed pelletization could improve energy utilization digestibility calcium phosphorus by broiler chickens. Three experiments were performed using 120 birds each, divided into five treatments with eight replicates per group (n = 3), identified as: experiment ...

the outbreak of sugarcane whitefly, neomaskellia andropogonis corbett has been recently recorded in sugarcane fields in khuzestan province. the seasonal population dynamics of n. andropogonis was investigated in sugarcane fields (cultivar cp69-1062) in amir kabir agro-industrial in khuzestan during 2006-2007. one hectar field in the middle of a large field (25 hectar areas) was selected randoml...

We evaluated the fects of different levels dietary silver nanoparticle (AgNP) powder on performance, intestinal microflora, carcass traits and blood parameters broiler chickens. Three hundred seven-day-old Ross chicks were randomly divided into five groups, each group replicated three times with 20 birds per replication. Chickens fed basal diet 2.5, 5, 10 mg AgNPs kg feed. Dietary inclusion imp...

Abstract This research was conducted aiming to find alternative antibiotics using local plants that are rich in antioxidants. The antioxidant content is used as a feed additive and an antibiotics, so livestock products safe from antibiotic residues.

The present study reports the effect of Emblica officinalis (EO) derived tannins on humoral immune responses and their protective efficacy against Eimeria infection in chickens. Tannins were extracted from EO and characterized by HPLC. EO derived tannins (EOT) and commercial tannins (CT) were orally administered in broiler chicks in graded doses for three consecutive days, that is, 5th-7th days...
