The objective of this work was to evaluate the supplementation of yellow natural pigment levels based on Marigold Flower extract (2%) and yellow synthetic pigment (Carophyll Yellow 10%) in sorghum-based rations for commercial laying hens and their influence on bird performance and egg quality. A completely randomized design was adopted with 5 treatments, 6 replicates, and 5 laying hens in each repetition. The treatments evaluated were: Sorghum based diet without supplementation with pigmentant - Negative Control; 150 g t-1 of Yellow Natural Pigment feed; 300 g t-1 of yellow natural pigment feed; 450 g t-1 of yellow natural pigment feed; 25 g t-1 of yellow industrial pigment feed. The Tukey test was applied at 5% for the analysis of the variables of performance and quality of the eggs. The variables related to external and internal egg quality and poultry yield performance did not present significant results (p > 0.05). Only the variable color of the yolk obtained significance (p < 0.01), with an increase according to the number of pigments included in the diet. Sorghum can be used together supplementation of natural and synthetic pigments in the diet to improve yolk pigmentation. It is recommended to include 450g t-1 of natural marigold flower pigment feed (2%) in sorghum-based diets for better pigmentation of the yolk in place of 25 g t-1 of yellow synthetic pigmented, by improving the color of the yolk and not interfering in the productive performance of the laying hens and the quality of the eggs.

“…Several studies (BITTENCOURT et al, 2019;SILVA et al, 2019;VALENTIM et al, 2020) report the effectiveness of alternative pigmenting sources to those commonly used (FASSANI et al, 2019). However, the inclusion of PPF may not have been enough to demonstrate its action.…”

The objective of this study was to evaluatethe effects of including pequi pulp flour (PPF) in laying hendiets onperformance and egg quality.A total of 240 Hisex Brown strain were randomly assigned into 5 groups and were fed diets containing PPF at the level of 0%, 0.125%, 0.250%, 0.375%, and 0.5%. The experiment lasted63 days (3 periods of 21 days).The variables of performance andeggquality were submitted to linear and quadratic regression analysis at the level of 5% probability.Theoutcomes suggest that neither performance nor egg quality wasaffected (p > 0.05) by different levels of PPF.Dietary inclusion ofPPFtested in the present study wasnot sufficient to demonstrate improvement in the productive performance of birdsas well as in egg quality.Because of the lack of responses, additional research is needed to evaluate higher levels of PPF in the diets for laying hens.

“…Segundo Silva et al (2019), a criação de poedeiras em gaiolas oferece melhores alternativas para a gestão da produção de ovos, além de favorecer aspectos sanitários e de mecanização. Outro fator benéfico é que, como a gaiola fica suspensa, as aves não entram em contato com as fezes, o que facilita a retirada de resíduos e reduz o problema de produção de amônia pelas aves.…”

O bem-estar animal é um assunto amplamente discutido na cadeia de produção. Nesse contexto surge a etologia, que é a ciência que estuda o comportamento animal, colaborando para melhor entender o animal em seu sistema de produção. Os estudos comportamentais da população avícola iniciam em sua organização social na natureza, procurando estudar fenômenos ligados à dominância e à submissão entre machos e fêmeas, organização familiar e domínio de território, entre outros fatores. A prática dessa ciência dá origem ao etograma, que é um registro por meio de observações do comportamento animal frente aos estímulos externos que evocam seus diferentes componentes. Dessa forma, o presente trabalho bibliográfico visa avaliar os aspectos comportamentais e produtivos dos animais com enfoque na avicultura, buscando entender a melhor aplicação dos etogramas para identificação do bem-estar animal. Esta ferramenta é importantíssima para que se descubram todas as potencialidades de cada espécie ou gênero animal estudado, oferecendo subsídios para orientação e exploração consciente pelo homem. O estudo da etologia ultrapassa a curiosidade científica exclusiva da zoologia. Tornou-se necessária para respeitar, além da exigência do mercado consumidor por Boas Práticas de Produção, o bem-estar do animal em foco. A aplicação do etograma se torna essencial para verificação dos comportamentos dos animais visando analisar fatores que possam ser prejudiciais para o bem-estar desses indivíduos e, também, sua produtividade. A implantação deste protocolo na criação de poedeiras comerciais objetiva o norteamento do bem-estar por parte das empresas produtoras e indústrias processadoras de ovos do Brasil. Palavras-chave: Avicultura. Comportamento Animal. Etologia. Abstract Currently, animal welfare is a subject widely discussed in the production chain. In this context ethology arises, which is the science that studies animal behavior, collaborating to better understand the animal in its production system. Behavioral studies of the poultry population begin in its social organization in nature, seeking to study phenomena related to dominance and submission between males and females, family organization and territory domain, among other factors. The practice of this science gives rise to the ethogram, which is a record through observations of animal behavior before external stimuli that evoke its different components. Thus, the present bibliographic study aims to evaluate the behavioral and productive aspects of animals with a focus on aviculture, seeking to understand the best application of ethograms to identify animal welfare. This tool is very important for discovering all the potentialities of each species or animal genus studied, offering subsidies for guidance and conscious exploitation by man. The study of ethology goes beyond the exclusive scientific curiosity of zoology. It became necessary to respect, in addition to the consumer market's demand for Good Production Practices, the animal welfare in focus. The application of the ethogram becomes essential to verify the animals’ behaviors in order to analyze factors that may be harmful to the welfare of these animals and also their productivity. The elaboration of this animal welfare protocol in the creation of commercial laying hens aims at the guide for the production companies and egg processing industries of Brazil, to adjust such needs of welfare assessment. Keywords: Bird Welfare. Animal’s Behavior. Ethology.
