  • Effect of early feed restriction and dietary inclusion of hot red pepper (Capsicum annuum L.), garlic (Allium sativum L.) and moleita baladi (Sonchus oleraceus) on broiler performance

A (3×4) factorial experiment was conducted with three early feed restriction programs (F0 without feed
restriction, F1 feed restriction for 12 hr and F2 feed restriction for 24 hr) and three dietary inclusion of spices (G0
without inclusion of spices, G1 garlic, G2 red hot pepper and G3 Moleita baladi) to study the effect of early feed
restriction and dietary incorporation of some spices on broiler performance. A total of 12 treatments were employed
and each treatment was replicated three times with ten birds each. Feed consumption, weight gain and feed
conversion ratio (FCR) were recorded. At the end of the experiment, two birds from each experimental unit were
selected according to their closed to average weight of the experimental unit and slaughtered. Carcass weight,
weights of some internal organs and cuts were measured. Blood samples were collected for determination of
cholesterol, triglycerides and protein. All the data obtained were statistically analyzed using ANOVA. The results
showed that Feed consumption, weight gain and FCR were affected by experimental treatments (p≤0.01). The
greatest feed consumed was reported with birds fed ad libitum basis. The birds fed on diets containing hot pepper had
the greatest value of feed consumption followed by garlic and moleita, while the birds fed on diets without spices had
the lowest value. The same pattern of results were observed with weight gain. Birds exposed to early feed restriction
for 24 hr (F2) had the heaviest weight gain value. Feed conversion ratio was improved when birds exposed to early
feed restriction. The best FCR was reported with birds fed on diets without spices. Carcass weights were influenced
by early feed restriction (p≤0.05). Internal organs weights (liver, spleen, pancreas and gizzard) were not affected by
experimental treatments. The only exception was observed with proventriculus weights which were affected by dietary
inclusion of spices. There was no significant effect (p≥0.01) of feed restriction treatments on blood protein. However,
the dietary spices treatments affected the blood protein. The highest and the lowest blood protein values were
recorded with garlic and moleita treatments, respectively. Blood cholesterol was not affected by different treatments.
Blood Triglyceride was influenced only by spices treatments. These results indicate that dietary inclusion of hot red
pepper and early feed restriction for 24 hours for broiler chicks elevated the body and carcass weights.

  • Antifungal Activities of Ethanolic Extracts of Sunut (Acacia nilotica L.) Bitter Apple (Citrullus colocynthis L. Schrad) and Mint (Mentha piperita L.) Against Fusarium moniliforme Sheldon

Natural products are substances or combinations of substances and elements found in nature and are used for the purpose of maintaining or improving health, treating or preventing diseases and control of vectors. The use of plant extracts to control plant diseases is gaining importance because of the growing awareness on the hazardous effects of chemical fungicides to human health and environment. The objectives of this study were to evaluate the antifungal activity of three different plant species selected and extracted for testing against the fungus Fusarium moniliforme, the causal agent of Mango Malformation Disease. These plants were : Acacia nilotica l. (Sunut), Citrullus colocynthis (Hanzal) and Mentha piperita (Mint) . The biological activity of Sunut seeds, Hanzel seeds, and Mint Leaves were tested by using antifungal quantitative method on PDA medium. Three different doses of ethanolic extracts, 1000, 2000 and 3000 ppm were selected according to preliminary tests. The growth inhibition zone (mm) was calculated as a percentage from the diameter of the control at 24,48 and72 hrs . All treatments were done in triplicates. The percentage inhibitions zone of fungal growth to each extracts were calculated. The results of the study revealed that, Inhibition zones for Hanzal extracts were 12.4, 10.9 and 10.8 mm and for Mint extract were 13.8d,18b and 18.7ab mm. Regarding Sunut extract , they were 15.1, 14.4 and 10.6 mm at 24,48 and 72,hr respectively. The ethanolic extracts showed inhibition activity and suppressed the Fungal growth. All selected plants exhibited moderate inhibition against the fungus. Among these plants, (Hanzal) showed the best effective results against the Fusarium moniliforme( 53%), followed by Mint( 49%), while Sunut showed the lowest  potential fungal inhibition (45%). The tested extracts were significantly effective in reducing the fungal growth as compared to the control.   The study recommended that, all Researches should be more keen towards the use of pesticides of botanical origin as an alternative to chemical pesticides which are harmful to the environment.
