Dietary chia (Salvia hispanica L.) improves the nutritional quality of broiler meat.

Objective: The current study was conducted to evaluate the quality and profile of fatty acid in the breast and thigh, and the performance of broilers fed diets containing seed or oil of chia (Salvia hispanica L.) as a replacement for soybean, in the rearing period from 29 to 42 days of age.

Methods: On the 29th day of age, 120 broilers were distributed in four treatments evaluated in five replicates of six birds.

Digestibility of Insect Meals for Nile Tilapia Fingerlings.

Insects are a valuable source of nutrients for fish, but little is known about their nutritional value for Nile tilapia fingerlings. To evaluate the nutritional value and energy apparent digestibility coefficient (ADC) of five insects for Nile Tilapia male fingerlings, 900 fish were distributed in 18 fiberglass conic tanks, in a completely randomized design, with six dietary treatments (control, meal (NCM) (Blattodea), larvae meal (ZMM) (Coleptera), meal (GPM) (Blattodea), meal (GAM) (Orthoptera) and larvae meal (TMM) (Coleptera)) and three replicates (tanks), each containing 50 fish. The control diet had no insect meal included and the other five treatments comprised 80% commercial diet and 20% test ingredient with 0.

Development and comparative analysis of single-drop and solid-phase microextraction techniques in the residual determination of 2-phenoxyethanol in fish.

Solid-phase microextraction (SPME) and single-drop microextraction (SDME) in headspace mode, were used in the residual determination of the anesthetic 2-phenoxyethanol in fish fillets, to ensure food safety. For the optimization of the methodologies the experimental central composite design (CCD) was used, resulting in accurate evaluations with less amount of analysis. The developed methodologies presented good precision in the evaluated range, o limits of detection (LD) and quantification (LQ) for SDME were 0.

Residual determination of anesthetic menthol in fishes by SDME/GC-MS.

The SDME-GC/MS method was applied to residual determination of anesthetic menthol in fish. The extractions took place from the headspace of the sample using 1.8µL of octane as the extraction solvent.

Milt cryopreservation for rheophilic fish threatened by extinction in the Rio Grande, Brazil.

Background: Specific protocols for milt cryopreservation have been established for some freshwater fish species. However, cryopreservation reduces sperm quality, giving unsatisfactory results in reproduction.

Objective: The objective of this work was to evaluate the effect of different cryoprotectants on the quality of Prochilodus lineatus, Brycon orbignyanus and Piaractus mesopotamicus milt after cryopreservation.

Effect of three feeding management systems on some reproductive parameters of Scorpion mud turtles (Kinosternon scorpioides) in Brazil.

Chelonians have been exploited since ancient times for their meat, eggs, fat, and offal, among other things. Among these animals, there is Scorpion mud turtle (Kinosternon scorpioides) which is an omnivorous turtle with semiaquatic habits and is widely consumed in Brazil. The aim of this study was to evaluate the influence of different feeding management systems on the reproductive performance of captive-bred Scorpion mud turtles, including egg quality and chemical composition.
