A study was conducted to assess the growth performance of broiler chickens fed Moringa oleifera leaf (MOL) feed supplement and challenged with a very virulent infectious bursal disease virus (vvIBDV). Two hundred and forty day-old Ross 308 hybrid broiler chicks were randomly assigned into groups A, B, C and D of 60 chicks each and were raised in deep litter housing. Broiler starter (BS) and broiler finisher (BF) mash were formulated each with 5% MOL included as part of the feed ingredient for broilers in groups A and B while BS and BF for broilers in groups C and D were formulated without MOL. Broiler chickens in groups A, B and C were challenged at 35 days of age with 0.05 ml of a live vvIBDV, while those in group D served as control. Daily feed intake (DFI), feed conversion ratio (FCR) and average body weight gain (ABWG) was used to assess the growth performance. At 42 and 49 days of age, significant difference was observed in the feed intake of broilers in groups A, B and C when compared with group D (p = 0.0001). At 49 days of age, broilers in group A and D significantly (p = 0.0001) added more weight than those in groups B and C respectively. Broilers in group B had a significantly (p = 0.0006) lower FCR than those in group A, C and D at 28, 35 and 42 days of age. Despite the challenge with vvIBDV, MOL inclusion in the diet of broiler chickens resulted in reduced DFI, good FCR, increased ABWG and final body weight and carcass weight.

This study was designed to assess the effect of Infectious Bursal Disease Virus (IBDV) on oxidative stress biomarkers in broiler chickens fed Moringa oleifera leaf (MOL) supplemented feed. Two hundred- and forty-day-old Ross 308 hybrid broiler chicks were randomly assigned into groups A, B, C and D of 60 chicks each.The chicks were raised on deep litter housing.Broiler starter (BS) and broiler finisher (BF) mash were formulated for broilers in groups A and B each with 5% MOL supplemented as part of the feed.while BS and BF were formulated without MOL for broilers in groups C and D. Broiler chickens in groups A, B and C were challenged with 0.05 ml of a live vvIBDV at 35 days of age, whereas those in group D served as controls. At days 35, 38, 42 and 49 of age, blood was collected from 10 broilers in each group via the wing vein to determine serum concentration of Catalase (CAT), Glutathione peroxidase (GPx), Superoxidase dismutase (SOD) and Malondialdehyde (MDA) using an Audiocomb Serum Auto-analyser.There was a significant increase in the concentration of CAT (P=0.0125) and GPx (P=0.0190), in broilers of group A at 38 days of age when compared with the control (group D). While the concentration of MDA increased significantly in broilers of group A (P=0.0004) at 42 days of age when compared with the control. Moringa oleifera leaf supplementation in the feed of broilers is shown to potentiate the antioxidant activities of CAT, GPx and MDA during infection with infectious bursal disease virus.

Potential Factor

Transmissible viral proventriculitis (TVP) of chickens is manifested in decreased body weight gains, poor feed conversion and weight diversity. Although TVP etiology has not been defined, a Birnaviridae family member, named chicken proventricular necrosis virus (CPNV) is considered as a potential factor of a disease. This study was undertaken in order to reproduce TVP and to evaluate its etiology. Broiler chickens of the TVP-infected group were inoculated with TVP positive proventriculi homogenate on the 24th day of life. Samples were collected, on infection day and 14 days post-infection (dpi). The 14 dpi anatomo- and histopathological evaluation, revealed that we have succeeded to reproduce TVP. TVP-infected birds gained 30.38% less body weight. In the TVP-infected group a seroconversion against picornaviruses, fowl adenoviruses (FAdV) and infectious bursal disease viruses (IBDV) was recorded with an ELISA test. Using RT-PCR and PCR, CPNV was detected in proventriculi and FAdV in spleens and livers of infected birds, 14 dpi. Our study supports that CPNV is involved in the development of TVP. We did not record the presence of IBDV in TVP or control birds, despite our recording of a seroconversion against IBDV in TVP infected birds. CPNV and IBDV belong to the same family, which allows us to assume serological cross-reactivity between them. The role of FAdV needs further evaluation.

Group D

In the present study, sterilized rice bran was fermented for 48, 72 and 96 hours by Aspergillus flavus and proximate analysis indicated that fermentation changed nutritive value of the rice bran. Four experimental feeds were fed to 4 groups of day old broiler chicks for 6 weeks to evaluate their effects on broiler performance (weekly feed intake, weight gain, FCR and mortality). During first 2 weeks, birds of group D showed significant difference (P less than 0.05) in feed intake and weight gain as compared to groups A (control), B and C. All groups did not show significant differences in feed conversion ratios (FCR). During 3rd week of trial, chickens of Group D showed significant difference (P less than 0.05) in feed intake, weight gain and FCR as compared to group A. During last 3 weeks, birds in group D showed significant difference (P less than 0.05) in feed intake, weight gain and FCR as compared to birds of groups A, B and C. Group D showed significantly higher weight gain and better FCR (P less than 0.05) as compared to groups A, B and C. On the whole, broiler chickens fed on 96 hours fermented rice bran showed best growth performance. In-vivo phytase activity was determined in ash of tibia bones collected from selected birds in each group. Group D showed significantly high percentage (P less than 0.05) of ash and phosphorus in tibia bones as compared to groups A (control), B and C. In conclusion, fermented rice bran showed beneficial effect on broiler performance and could be used in poultry feed as phytase source.
