Raising systems and diet type in Japanese quails production: Effects on growth performance, carcass characteristics, fatty acid profiles and meat quality.

This study evaluated the effects of raising systems and diet types on growth performance, carcass characteristics, pH content, fatty acid profiles and meat quality in Japanese quail (Coturnix japonica). A total of 608 seven-day-old quail chicks were arranged in a 2 × 2 factorial design, with two raising systems (cage and free-range) and two diet types (conventional and organic). The experiment employed a completely randomized design with four treatments, four replicates per treatment, and 38 birds per replicate.

Protein Hydrolysates from Fishery Processing By-Products: Production, Characteristics, Food Applications, and Challenges.

Fish processing by-products such as frames, trimmings, and viscera of commercial fish species are rich in proteins. Thus, they could potentially be an economical source of proteins that may be used to obtain bioactive peptides and functional protein hydrolysates for the food and nutraceutical industries. The structure, composition, and biological activities of peptides and hydrolysates depend on the freshness and the actual composition of the material.

Aflatoxin levels in poultry feed: a comparison of mash and pellet forms.

The current research was conducted to determine the aflatoxigenic and non-aflatoxigenic Aspergillus flavus isolates and the frequency of aflatoxin levels (B, B, G, G), in main feed ingredients (corn and soybean meal) and poultry finished feed (in mash and pellet forms). Eighty-five samples of corn, soybean meal, and poultry finished feed was randomly collected from feed mills in Iran. Regarding macro and microscopic morphological criteria, Aspergillus isolates were identified, and aflatoxins were determined by thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC).

Social, economic and environmental vulnerability: The case of wheat farmers in Northeast Iran.

This research used a qualitative and quantitative approach to classify factors influencing wheat farmers' social, economic, and environmental vulnerability in Khorasan Razavi province, Iran, from the perspective of elite wheat farmers and agricultural specialists, and then to establish some recommendations based on the results. To achieve the study objectives, in the qualitative part, in-depth interviews were held with 20 agricultural specialists in the field of wheat cultivation, and 9 elite wheat farmers were selected using a purposive sampling method. Using stratified random sampling, 391 wheat farmers participated in the quantitative part.

Toxigenicity and phylogeny of section in poultry feed in Iran.

Background And Purpose: This study was conducted to evaluate the presence of aflatoxigenic strains and level of aflatoxin in poultry feed. Aflatoxigenic strains were investigated in corn and soybean meal as the ingredients of poultry feed, as well as in two types of commercial feed, namely pellet and mash. The gene sequencing was performed to identify the species of section

Materials And Methods: All samples were randomly collected from feed storage silos located in Iran in 2018.
