El presente estudio cuantificó los niveles de Dietilestilbestrol (DES), zeranol y acetato de trembolona por ensayo inmunoenzimático en muestras pechugas de pollo comerciales de origen nacional e importado. Se utilizaron 72 muestras de pechuga de pollo de origen nacional e importado, y se detectó la presencia de zeranol y trembolona en las muestras...

El quitosano es un polímero que se obtiene a partir de subproductos de crustáceos, el cual posee propiedades antioxidantes, antimicrobianas e inmunoestimulantes que pueden ser aprovechadas para la promoción del crecimiento en aves de corral sin alterar su estado de salud. El objetivo del estudio fue evaluar el efecto de la inclusión dietética de qu...

Four isonitrogenous (45% crude protein) and isoenergetic (20.29-20.47 kJ/g) experimental diets were formulated by replacing 0%, 10%, 20% and 30% of fish meal (FM) with shrimp head meal (SHM) as a source of protein and tested the rearing performance and skin coloration of spotted rose snapper Lutjanus guttatus. The SHM had a high content of protein...

The objective was to identify the presence and concentration of the hormones Diethylstilbestrol (DES), zeranol and trenbolone acetate using an immunoenzymatically assay in local and imported chicken breast samples. 72 samples of breast of local and 72 samples of imported origin were used, zeranol and trenbolone were detected of local and imported m...

Chitosan is a natural polymer with different bioactive properties that can be used in non-ruminant species as chicks. The objective of the present study was to evaluate the dietary inclusion of 0.55% of chitosan on growth performance and blood metabolites in Rhode Island Red chicks under confinement conditions. A total of 30 chicks with an average...

The effect of diets with varying crude protein-to-precooked cornstarch (P:S) ratios on growth performance, feed efficiency, carbohydrase activity, and blood chemistry of juvenile Lutjanus guttatus was evaluated. Four isoenergetic (19.0 kJ g-1) diets containing different P:S ratios (46:18, 38:30, 34:35, and 31:40) were formulated to feed fish for te...

Marine by-products can compose up to 70% of the total weight of products from fisheries, most of which are discarded. However, these by-products are rich in highly unsaturated fatty acids that are not synthetized by most marine animals produced by aquaculture. Here, we used three marine by-products (shrimp head, Catarina scallop viscera, and Pen sh...

The fruit, vegetable, legume, and cereal industries generate many wastes, representing an environmental pollution problem. However, these wastes are a rich source of antioxidant molecules such as terpenes, phenolic compounds, phytosterols, and bioactive peptides with potential applications mainly in the food and pharmaceutical industries, and they...

Antecedentes y Objetivos: Los eventos fenológicos en manglares suelen estar influidos por factores como la salinidad del agua, fotoperiodo y/o temperatura ambiental. Esto se ha documentado principalmente para especies de la familia Rhizophoraceae y Acanthaceae; sin embargo, son limitados los estudios accesibles para la familia Combretaceae, p. ej....

A 60-day feeding trial to determine the nutritional value of marine by-product meals in diets for longfin yellowtail Seriola rivoliana juveniles (48.1 ± 0.6 g initial weight) was conducted. Five diets were evaluated: a reference diet (RD; 500 g kg−1 CP, 130 g kg−1 L), containing 500 g kg−1 of fish meal (FM); three experimental diets with 125 g kg−1...

A 12-week feeding trial was conducted to examine the replacement of fish meal with pet-grade poultry by-product meal (PBM-PG) in the spotted rose snapper Lutjanus guttatus diet. Five experimental diets were formulated to contain graded levels of PBM-PG at proportion of 250, 500, 75 or 900 g kg−1. The control diet contained sardine fish meal as the...

The feasibility of replacing fish meal protein at different levels with poultry by product meal food grade (PBM-FG) was assessed in diets for spotted rose snapper Lutjanus guttatus. Four diets were formulated, the control diet fish meal was used as the main protein source (FM); the other three diets had increasing levels of PBM-FG replacing 25, 50...
