“…To our knowledge, pumpkin pomace has been used as a feed ingredient in some species of monogastrics, such as pigs [33] and broilers [34]. In our study, the growth parameters and survival of shrimp fed diets including Japanese pumpkin pomace were not affected.…”

“…Two diets were formulated with pomace, including 50 g•kg −1 (PP50) and 100 g•kg −1 of pumpkin pomace powder (PP100), and a control diet was formulated without the inclusion of pumpkin seeds or pomace powder. The inclusion levels of Japanese pumpkin by-products were based on previous studies that evaluated the inclusion of pumpkin seeds in fish feed [22] and the inclusion of pumpkin pomace in monogastric feeds, such as pigs [33] and broilers [34]. The formulations and nutrient profiles of the experimental diets are presented in Table 2.…”

A 60-day feeding trial was conducted to evaluate the effects of including pumpkin seeds and pomace in the diets of Pacific white shrimp Penaeus vannamei, and the effects of these supplements on growth performance, body composition, and total polyphenol, flavonoid and carotenoid contents, as well as on total antioxidant activity, and body color parameters. Five diets were evaluated: pumpkin seeds (PS) at 50 and 100 g·kg−1, pumpkin pomace (PP) at 50 and 100 g·kg−1, and a control treatment. Pacific white shrimp (P. vannamei) juveniles (0.60 ± 0.01 g) were stocked in 15 tanks (310 L), containing 30 shrimps per tank, and the treatments were randomly distributed in triplicate. At the end of the experiment, shrimps were euthanized, weighed, and dissected for further analyses. The inclusion of PS in the diets impaired growth performance, reduced the total flavonoid content and had a pro-oxidative effect on muscle. The inclusion of PP in the diets did not affect growth performance, improved the feed conversion ratio, increased the total flavonoid content in the diets and hepatopancreas, and improved the antioxidant activity of the feeds and shrimp muscle. The total carotenoid content of the feeds increased with the inclusion of PS or PP in the diets; however, the total carotenoid content of shrimp increased only in those fed PP diets. Shrimp fed with PS diets showed a yellowish color and higher saturation when fresh and a reddish color and yellow hue angle after cooking. Shrimp fed PP diets turned reddish and yellowish, both when fresh and after cooking. The inclusion of PS in P. vannamei diets is not recommended; however, PP can be included at 100 g·kg−1 without affecting the growth parameters. Further studies evaluating the inclusion of higher PP levels in shrimp diets are recommended.

This research was carried out at the Santa Inés farm (Faculty of Agricultural Sciences, Universidad Técnica de Machala), El Oro Province, Ecuador. The main objective was to evaluate the effect of Moringa oleifera leaf meal on the productive and economic parameters of Cobb 500 chickens. For the biosecurity and well-being of the birds, a pre-established managemet for open-shed systems in the area was used, applying a basic vaccination schedule to the chickens. For the experiment, a Completely Random Design (CRD) was applied, using 200 Cobb 500, newborn mixed chickens (male and female), distributed in 5 treatments and evaluated for 35 days, each treatment had 4 experimental units of 10 chickens. The disposition of the groups was as follows: control (T1) to which only the basal diet; T2, T3, T4 and T5 in which 1, 2, 3, 4% of M. oleifera leaf meal was administered in the feed, respectively. The variables evaluated were: live body weight, feed consumption and accumulated water, feed conversion ratio, mortality, productive efficiency factor, kilograms of meat per square meters (m2) and economic expenses. To determine the possible differences, the statistical software Statgraphics Centurion XV.I.®, was used. A parametric analysis of one factor (ANOVA), prior to the assumptions of normality and homogeneity was used. In order to discriminate among the means, the Bonferroni multiple comparison procedure was applied with a confidence level of 95%. The results showed that there is an effect on live weight and feed intake, because diets with an inclusion greater than 3% were negatively influenced in the first 3 weeks of life of the animal, while the rest of the variables were not affected.

“…Este fruto tiene como característica especial el gran aporte de carotenoides (Rodríguez et al, 2014), principalmente los carotenoides α-caroteno, β-caroteno y Luteína (Mendoza et al, 2020). Por su parte, Rodríguez et al (2018) resaltaron que la harina de C. moschata presenta gran contenido de fibra, almidón y carbohidratos lo que la convierte en una alternativa viable para la alimentación animal.…”

La investigación tuvo como objetivo evaluar la inclusión de Cucurbita moschata sobre los parámetros productivos de pollos de engorde tales como peso final, consumo de alimento, ganancia de peso, conversión y eficiencia alimenticia, rendimiento en canal y costos por concepto de alimentación. Se empleó un diseño totalmente aleatorizado con cuatro tratamientos: 5 %, 10 % y 15 % de C. moschata que corresponden al reemplazo parcial del alimento balanceado comercial y un control, cada uno con 10 unidades experimentales. La dieta se implementó a partir del día 22 hasta el día 45. Se utilizó el análisis de varianza para el tratamiento de los datos y la prueba de Tukey para la comparación de medias con una significancia del 5 %. La regresión polinomial y la derivada de una función cuadrática fueron empleadas para determinar el nivel óptimo de C. moschata. Los resultados del ANOVA mostraron un comportamiento similar entre los tratamientos y el control (p < 0,05). El nivel óptimo de inclusión de C. moschata fue de 3,5 %, 3,2 % y 6,5 % para ganancia de peso, conversión alimenticia y consumo respectivamente. El T3 presentó el mejor costo por concepto de alimentación con una media de $2.431,68. Se concluye, que la inclusión de C. moschata en aves de engorde permite obtener rendimientos productivos similares a la alimentación convencional con productos balanceados comerciales a un costo más bajo.
