The effect of the mannan-oligosaccharide Bio-Mos on broiler chicken performance, after its incorporation in the starter diet was evaluated. A total of 53,040 one day-old Cobb chicks, randomly divided into two groups with four replicates each, were used in a feeding trial that lasted 40 days. One of the groups (Control group) was fed on a basal commercial starter diet, while the other (Bio-Mos group) was given up to day 10 of age the same diet supplemented with the mannan-oligosaccharide Bio-Mos at the level of 1.5 g/kg of feed. From day 11 of age and thereafter, Bio-Mos administration was discontinued and both groups were given the same basal commercial grower and finisher diets. Results showed that chickens in the Bio-Mos fed group exhibited a significant (P<0.05) improvement in body weight compared to control at day 10 (295 vs 254 g) and day 40 (2108 vs 2017 g) of age. Feed intake per bird from day-old to day 40 of age showed a significant (P<0.05) increase in the Bio-Mos group compared to control (3647 vs 3612 g), whereas feed conversion ratios also demonstrated a significant (P<0.05) improvement for the Bio-Mos group (1.73 vs 1.79). Mortality rate was lower in the Bio-Mos group compared to control (2.5 vs 2.9%), however, the difference was not statistically (P>0.05) significant.

Aquaculture is considered as a promising alternative to support the food demands of the everincreasing population. Currently, this sector faces several challenges such as using fishmeal, which is unsustainable and expensive. Therefore, it is necessary to identify an alternative feed component that is sustainable, cost-effective and can provide the essential nutrients required by the fish. In this context, microalgae are considered as a viable source of proteins, lipids, polysaccharides and highvalue products (HVPs) such as essential fatty acids, amino acids and vitamins. They play a vital role in the marine food chain and hence can be easily assimilated by the fish. The current research targeted the isolation, identification and characterization of novel marine microalgae from Qatar coastline to produce aquaculture feed supplement. As the climate poses a number of stress factors, such as high light intensities, temperatures and varying salinities, it is expected that novel microalgae with interesting metabolite profiles can be isolated from the environment for developing aquaculture sector in Qatar. Standard plating methods were used to isolate halophilic strains from field waters. PCR-sequencing was used to identify the novel microalgae, cyanobacteria and diatom isolates. Then a comparative analysis of the growth performance and metabolite content was performed to characterize these strains. Results evidenced that the cyanobacteria strain exhibited the highest biomass productivity of 51.4 mg L-1day-1 whereas the highest lipid content was observed in the novel diatom isolate ranging up to 28.62% and the highest amount of carotenoids was detected in the case of the microalgae. As in conclusion, a rich feed supplement blending the three isolates can be considered as an alternative to fishmeal. As a continuation of this research, the potential strains will be cultivated under various stress to increase their nutritional value.

This study examined the effect of Mucuna seed powder (MSP) supplementation on performance, meat, and health status of broiler chickens. A total of 300 broiler chicks were randomly allocated into 5 treatments with 6 replicates of 10 birds each, as follows: Diet 1 (control), Diet 2 (diet supplemented with 1.1% oxytetracycline, OXYT), Diet 3 (diet with 0.5% MSP), Diet 4 (diet with 1.0% MSP) and Diet 5 (diet with 1.5% MSP). The dietary MSP supplementation significantly (P<0.05) increased the daily body weight gain of the broiler chickens, compared to those fed the control diet at the starter phase and overall (1-42 days) period of the feeding trial. No significant differences were observed in the measured aspartate aminotransferase (AST), creatinine, and alanine aminotransferase (ALT) among the treatments. The broiler chicken fed diets supplemented with MSP had higher (P<0.05) total serum glutathione peroxidase and superoxide dismutase compared to those fed the control diet. The concentration of muscle cholesterol and lipid peroxidation reduced significantly (P<0.05) in the birds fed MSP supplemented diets compared to those fed the control diet. In conclusion, this study has shown that MSP can be used up to 1.5% as a potential phytogenic feed supplement in a broiler diet to enhance the growth performance, maintain the carcass traits, boost endogenous antioxidants and reduce meat cholesterol level and lipid oxidation.

The effects of processed and undehulled sunflower seed (PUSS) as feed supplement, on the performance of growing rabbits was studied. The eight weeks feeding trial involving twenty four, six weeks old male and female New Zealand white rabbits weighing 600-650g in a completely randomized design were fed three diets containing 0% (control), 10% and 20% processed and undehulled sunflower seeds. The processed and undehulled sunflower seed was high in both fat and fibre levels (25.42 and 29.82%) respectively but low in both protein and nitrogen free extract (17.92 and 16.48%) respectively. The 10% level of inclusion of PUSS in the diet gave significantly (P<0.05) better weight gains than the 20% PUSS. Feed efficiency and protein efficiency were similar for the control and 10% PUSS supplements, which were both superior (P<0.05) to the 20% PUSS diet. There was no incidence of enteritis or mortality among the treatment groups.
