Problem statement: Using most of antibiotic growth promoters as feed additives has been banned by the European Union due to cross-resistance against pathogens and residues in tissues; and scientists search for alternatives to antibiotics, two days. In this view, medicinal plants and essential oils extracted are becoming more important due to their antimicrobial and stimulating effects on animal digestive systems. Approach: This study was conducted to evaluate the use of Pumpkin oil in broiler nutrition as a natural growth promoting substance and its effect on abdominal and blood fat. A total of 144 one-day-old broiler chicks (Ross 308) were used in a completely randomized design with 3 treatments and 3 replicates. The experiment was conducted from 29-49 d of age. The main ingredients of diets included corn, soybean meal and wheat. The pumpkin oil levels added to the diets were 0.00 (control), 5.00 and 10.00 g kg −1 DM. Results: Pumpkin oil supplementation up to 5.00 g kg −1 DM diet had not significant effect on broilers performance, but supplementation in higher level (10.00 g kg −1 DM) significantly decreased broilers performance. Pumpkin oil supplementation decreased bird's mortality. Adding pumpkin oil had not any significant effect on abdominal fat pad and carcass composition, however cholesterol and triglyceride concentrations in plasma decreased at 49 days of age (P<0.05). Conclusion: Results of this study indicated that supplementation of diets with 5.00 g kg −1 DM pumpkin oil in corn-soybean meal-wheat based diet can be profitable because it reduced broiler chicken's mortality and it did not have any adverse effect on bird's performance.

“…Furthermore, an increasing interest in this vegetable has also been reported in other countries (Gwanama, Botha, & Labuschagne, 2008). Tissue from this kind of pumpkin was characterized previously (de Escalada Pla, Ponce, Wider, Stortz, Rojas, & Gerschenson, 2005;de Escalada Pla, Delbon, Rojas, & Gerschenson, 2006;de Escalada Pla, Ponce, Stortz, Gerschenson, & Rojas, 2007).…”

In the present study, pumpkin (Cucurbita moschata Duchesne ex Poiret) was used as raw material to produce sweet food fortified with iron (Fe) and ascorbic acid (AA). A dry infusion process with a subsequent air drying was applied. Response surface methodology was performed in order to analyze the effect of Fe and AA incorporation into the formulation on: water loss (WL) and solid gain (SG) during the dry infusion process, color changes (∆E) and the dehydration percentage during subsequent air drying process. The results showed that the presence of Fe and/or AA promoted SG and WL during the dry infusion and also, weight changes during the air drying process (PP). An increase of the color changes was also observed. In turn, it was possible to obtain predictive equations for the parameters studied. The application of edible coating based on tapioca starch on pumpkin product was also tested showing a protective effect from the pumpkin color view point.

“…22,23 In fact, tropical pumpkin (C.moschata) is one of the most important vegetable crops in some African countries. 24 In general, C. maxima is more important in the cooler parts of southern Africa and the Sahel region, and less important in west and east Africa, where it is more humid, and where C. moschata is more common. Our results fit with this information.…”

HOW TO CITE:A survey was carried out in Angola with the aim of collecting vegetable crops. Collecting expeditions were conducted in Kwanza-Sul, Benguela, Huíla and Namibe Provinces and a total of 80 accessions belonging to 22 species was collected from farmers and local markets. Species belonging to the Solanaceae (37 accessions) and Cucurbitaceae (36 accessions) families were the most frequently found with pepper and eggplant being the predominant solanaceous crops collected. Peppers were sold in local markets as a mixture of different types, even different species: Capsicum chinense, C. baccatum, C. frutescens and C. pubescens. Most of the eggplant accessions collected belonged to Solanum aethiopicum L. Gilo Group, the so-called 'scarlet eggplant'. Cucurbita genus was better represented than the other cucurbit crops. A high morphological variation was present in the Cucurbita maxima and C. moschata accessions. A set of 22 Cucurbita accessions from Angola, along with 32 Cucurbita controls from a wide range of origins, was cultivated in Valencia, Spain and characterised based on morphology and molecularity using a set of 15 microsatellite markers. A strong dependence on latitude was found in most of the accessions and as a result, many accessions did not set fruit. The molecular analysis showed high molecular variability and uniqueness in the collected accessions, as shown by their segregation from the set of global controls. In summary, the material collected is quite valuable because of its uniqueness and the potential of the breeding characteristics it possesses.
