Abstract:
Introduction: Poultry production has increased during the past half century throughout the world. In Burkina Faso modern poultry farming is becoming a necessity in view of the growing demand for eggs. Intensive poultry farming is developing rapidly, given that the productivity of local poultry remains very low Because of the low availability and high cost of food. Therefore, it becomes imperative to develop strategies to make modern poultry farming more productive, by finding alternative solutions for feeds. Objective: The study aims to evaluate the effects of diets incorporating mango waste-based feed on the growth parameters of laying hens and biometric parameters of first eggs. Methods: Two hundred and ten (10) hens of the Isa Brown breed were divided into 3 batches (70 chicks per set) and feed with three diets namely mango and maize diet (MMD = lot1), control maize diet (CMD = lot2) and absolute control diet (ACD = lot3) in a feed experiment at INERA research station in Farako-ba, Bobo Dioulasso. Results: The final average weight (FW) gained by the lot1 and lot3 using the diet CMD (1364 ± 114 g) and ACD (1364 ± 115 g), respectively was significantly higher than the lot 2 feed with the MMD diet (1265 ± 117 g) (p < 0.05). The average daily weight gain (ADG) of CMD and ACD was significantly (p < 0.05) higher than that of the MMD ration. The feed intake (FI) and consumption index (CI) of the MMD ration were significantly (p < 0.05) higher than those of CMD and ACD (p > 0.05). Average weight and egg density were similar (p > 0.05) for the three diets. The eggs on the MMD diet were larger (p < 0.05) than those in the ration’s CMD and ACD, but the two later were similar (p > 0.05). Conclusion: Maize can be substituted with mango feed in growing layer diets. Mango waste-based feed is predisposed for better preparation of growing layers for good laying performances. It is an alternative to increase the availability of feed for farm animals including the laying hen.

Agriculture & Food Security , 2012, DOI: 10.1186/2048-7010-1-13
Abstract: Eating patterns are important for building sustainable food and agricultural systems. This paper begins by presenting the main features of eating patterns worldwide. These eating patterns include the relative convergence of diets, more rapid food transition in emerging and developing countries, development of a more complex food chain, and substantial food losses and waste at distribution and final consumption stages. These patterns have negative consequences on health and the environment. The drivers of these patterns are examined to identify knowledge gaps, the filling of which should facilitate the design and implementation of actions and policies aimed at making food systems more sustainable.

International Journal of Poultry Science , 2008,
Abstract: The current research objective was to determine the effect of enriched layers diets containing date waste meal (DWM) with a commercially prepared enzymes mixture on White Lohmann laying hens performance. Lohmann LSL-Classic White layers of (24-weeks old; n = 192) were randomly assigned to 8 groups of 24 birds each. Four formulated diets of 18% crude protein which contained 0, 5, 10 and/ or 15% DWM as a replacement for yellow corn, each diet was supplemented with of kemzyme (EZ) at 1 gm/kg diet until 44 weeks of age. Results showed that body weights and body weight changes due to 15% DWM inclusion and EZ supplementation were improved. Egg production, egg weight and feed conversion ratio were improved by EZ supplementation to diets containing 15% DWM. Enzyme and DWM supplementation to experimental diets had a positive effect on salmonella and E. Coli as well as fungi counts in the gastrointestinal tract. Also, EZ supplementation had improved nutrients digestibility coefficient of diets that contained higher DWM levels. Plasma total lipids were significantly (P ≤ 0.05) decreased with higher DWM levels, while total lipids of fresh eggs were higher than that of stored eggs. On the other hand, EZ supplementation had no significant difference (P ≥ 0.05) in this respect. Inclusion of 15% DWM significantly (P ≤ 0.05) improved shell thickness and Haugh units with higher DWM levels. No significant differences were recorded for yolk color or index due to either of the dietary treatments. It is concluded that DWM can be included in laying diets as an alternative dietary ingredient up to 10% with no adverse effects on production, and showed an improvement on performance when compared to that of the control diet supplemented with enzymes mixture.

International Journal of Poultry Science , 2006,
Abstract: Nutritional and economic evaluation of the dietary inclusion of Danish (imported) fish meal, crayfish dust meal and shrimp waste meal as animal protein sources in broiler ration was carried out using 144-day old broiler chicks in a completely randomized design experiment. This trial lasted seven weeks. The 144 – unsexed chicks of. Anak Strain were randomly allocated to 6 dietary treatments, with each having 2 replications of 12 chicks per replicate. The diets were designated as diets 1,2,3,4,5 and 6. Diets 1, 2 and 3 respectively had 6% Danish fish meal, crayfish dust meal and shrimp waste meal, while diets 4, 5 and 6 respectively contained 3% each of crayfish dust meal and shrimp waste meal. The birds were fed and watered ad libitum. Proximate analysis showed that the test ingredient (FM, CFDM and SWM) respectively had a crude protein content of 61.34%, 65.27% and 46.20%. The gross energy were 2614kcal/kg, 3625kcal/kg and 2982kcal/kg in that same order. The mean final body weight, daily weight gain, daily feed intake and feed - to -gain ratio showed no significant difference (P>0.05). Birds fed diet 4 gave the best (2.05) feed-to-gain ratio and weight gain. The nutrient and mineral utilization analysis showed significant variation (P< 0.05) in the percent nitrogen and energy retention as well as calcium and phosphrous retention values among the diets. Birds fed diet 2 had their nitrogen retention improved (83.32%). The cost analysis indices showed significant (P< 0.05) differences. Diet 4 was the cheapest (N39.07) per kilogramme while diet 1 gave the least marginal revenue (N451.34). From the foregoing, the Danish fishmeal, crayfish dust meal and shrimp waste meal are generally comparable and had no adverse effect on the performance and economic of broiler production through the combination of crayfish dust meal and shrimp waste meal proved to be the best diet. This is an indication that satisfactory animal protein can be prepared from these unconventional sources.

Abstract: Mangiferin (1,3,6,7-tetrahydroxy xanthone-C2-b-D-glucoside) promoted vegetative growth and exhibited inhibitory role on the occurrence of malformation. Mangiferin changes associated with mango malformation pathogens were followed after inoculated mango seedlings (three years) with malformation pathogens i.e. Fusa-rium subglutinans, F. sterilihyphosum, F. oxysporum and F. proliferatum. Mangiferin remained at lower level in leaves of malformed shoots as compared to healthy one. The floral malformation was observed to be associated with the reduction of mangiferin. Strong positive correlations between mangiferin activity and malformation incidence were observed. Mangiferin level at panicle initiation may give a possible estimate of malformation incidence in mango.

Abstract: Diagnostic tests by molecular biology is made for studying the relations among Fusarium species for linking production of proteins, degree of relationship and occurrence of malformation. Determination of proteins for isolates causing-disease by SDS-PAGE explained there’s specific band for each fungus and there are common bands among some isolates of fungi. Since, band with MW 30 KDa represented only in F. proliferatum and F. oxysporum and F. subglutinans respectively. This band considered as specific band for these isolates, which released high pathogenisity effect. RAPD–PCR markers were used to discriminate variations between Fusarium isolates and causing disease. There is specific band for each fungus which act as molecular marker for each fungus and there are some bands common among some isolates of pathogenic fungi. The dendrogram shows there is degree of relationship between F. sterilihyphosum and F. proliferatum; between F. moniliforme and F. subglutinans; between F. oxysporum and F. chlamydospore; the degree of relationship among F. subglutinans, F. proliferatum and F. sterilihyphosum and degree of relationship among F. moniliforme, F. sterilihyphosum, F. proliferatum and F. subglutinans

Abstract: Eight Fusarium species i.e. F. subglutinans, F. solani, F. oxyspoum, F. sterilihyphosum, F. proliferatum, F. monili-forme, F. avena and F. chlamydspore isolated from mango malformed disease were tested for their ability to cause mango malformation disease and their production of moniliformin and total fumonisins (FB1 + FB2) using HPLC. A evaluated for moniliformin production, seven isolates were toxin producers, the production levels ranging from 0.51 to 8.90 µg/ml. The higher levels were produced by Fusarium subglutinans (8.51 µg/ml). Moderate concentrations of moniliformin was produced by F.moniliforme (6.90 µg/ml), F. oxysporum (6.30 µg/ml), F. proliferatum (4.10 μg/ml) and F. sterilihyphosum (1.10 μg/ml). Separation and identification of Fumonisin that was isolated from the pathogen- causing disease are made by (HPLC). A evaluated for total fumonisin production (FB1 + FB2), seven isolates were toxin producers, the production levels ranging from 0.10 to 8.30 µg/ml. The higher levels were produced by F. monili-forme (8.30 µg/ml. Moderate concentrations of fumonisin was produced by F .proliferatum (0.64 µg/ml) and F. subglutinans (0.50 µg/ml). Strong positive correlations between moniliformin and total fumonisins (FB1 + FB2) activities and malformation disease incidence by F. subglutinans, F. solani, F. oxyspoum, F. sterilihyphosum, F. proliferatum was observed.

Abstract:

Mangifera indica (mango) is a typically tropical fruit with considerable economic value. Brazil features a wide variety of cultivars of this fruit, most of which are known under several different names. Indeed, the nomenclature of mango varieties is still quite confusing. Up to now there has been no well-defined scientific principle to differentiate them. The objective of the present work is to compare the different clustering methods in assessing genetic divergence among mango accessions, as well as identify the minimum efficient descriptors for that crop. A total of 20 mango accessions in Cáceres, Mato Grosso state, Brazil were evaluated. When building dissimilarity matrices, the descriptors were divided according to the following groups: leaf, flower/inflorescence, fruit, seed and growth habit/ripening period. With these divisions, combinations were performed among the groups of descriptors. The similarity index was used to obtain the dissimilarity matrices. Later, the accessions were clustered using the methods of Tocher, Ward and UPGMA. The study observed that it was possible to reduce the number of descriptors from 64 to 35, and that the clustering methods were compatible with the study of the genetic diversity of mango.

Abstract: We isolated naturally occurring actinomycetes with an ability to produce metabolites having antifungal property against, Colletotrichum gloeosporioides, the causal agent of mango anthracnose. One promising strain was strong antifungal activity, was selected for further studies. Based on the physiological and biochemical characteristics, the bacterial strain was identical to Streptomyces aureofaciens. Culture filtrate collected from the exponential and stationary phases inhibited the growth of fungus tested, indicating that growth suppression was due to extracellular antifungal metabolites present in culture filtrate. Isolate highly produced extracellular chitinase and β-1,3-glucanase during the exponential and late exponential phases, respectively. In order to standardize the metabolite production some cultural conditions like different incubation time in hours, pH, carbon sources and concentrations and nitrogen source were determined. During fermentation, growth, pH and hydrolysis enzymes production were monitored .Treatment with bioactive components exhibited a significantly high protective activity against development of anthracnose disease on mango trees and increased fruit yield.
