“…In this study, there was an evident change in the feed intake, where the inclusion of fish by-product meal resulted initially in an increased intake, which, according to the aforementioned authors, is because products of animal origin directly affect the palatability of the food, and birds have a predilection for foods with medium to high lipid content (Freitas et al, 2013;Nogueira et al, 2014). Also in this context, a decrease in consumption was observed, which may be related to the energy needs of the birds caused again by the lipid content observed in the composition of fish by-product meal and its effect when included in larger quantity in the diets.…”

ABSTRACT. This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 16052-wk-old Dekalb White hens were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish byproduct meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that fish by-product meal can be used in diets for hens as alternative feed, with better results in egg production, feed conversion, egg weight, yolk-albumen ratio and a reduction in feed cost and production cost.Keywords: alternative feed, economic available, feed cost, lipid profile, performance. Farinha de resíduo de pescado em rações de poedeiras comerciais levesRESUMO. Objetivou-se com este estudo avaliar a inclusão de níveis crescentes (0, 1, 2 3 e 4%) de farinha de resíduo de pescado na dieta de poedeiras comerciais leves sobre o desempenho, qualidade do ovo e análise econômica. Foram utilizadas 160 poedeiras da linhagem Dekalb White com 52 semanas de idade. O experimento teve duração de 84 dias divididos em quatro períodos de 21 dias. O delineamento experimental foi o inteiramente casualizado com cinco tratamentos contendo quatro repetições de oito aves cada. As estimativas dos níveis de farinha de resíduo de pescado foram determinadas por meio de regressão polinomial. Foram observadas diferenças (p < 0,05) em todas as variáveis de desempenho, no peso do ovo, percentagem de gema e albúmen, altura de gema e albúmen, custo alimentar e custo de produção, onde a inclusão de farinha do resíduo de pescado proporcionou melhores resultados. Concluiu-se que a farinha de resíduo de pescado pode ser utilizada como alimento alternativo em rações para poedeiras comerciais leves, proporcionando melhora na produção de ovos, conversão alimentar, peso do ovo, relação gema-albúmen, redução no custo alimentar e no custo de produção.Palavras-chave: alimento alternativo, custo, desempenho, perfil lipídico, viabilidade econômica.

“…The guava extract ellagic acid was ineffective to improve the egg quality. Freitas et al (2013) confirmed that the use of synthetic antioxidant or ethanolic mango extracts do not affect the breeder's performance, but it improves the albumen quality and the lipid eggs stability. Oliveira et al (2018) verified that the use of copaiba and sucupira oils in the breeder's diet have a positive impact in the albumen quality and the yolk's pH.…”

SUMMARY The aim of this study was to evaluate the guava extract as an antioxidant additive in diets of Japanese quail breeders on the performance and egg’s quality. The experiment was conducted at University Federal of Goias. A total of 384 Japanese quail breeders were used, distributed in four treatments, with six replicates, with a total of 12 females and four males in each replicate. The treatments were performed with four levels of guava extract in the diets (0.0%, 0.3%, 0.6% and 0.9%). The guava extract contained the ellagic acid, considered the guava antioxidant active principle. The diets were isonutritive. Feed and water were offered ad libitum. The experimental period was 84 days. Egg production, feed intake, feed conversion ratio, egg mass, body weight variation and egg quality were evaluated. The results were submitted to analysis of variance and regression analysis. The adopted probability was 5%. Egg production, feed intake, feed conversion ratio and egg mass were not influenced by the use of guava extract. The yolk and albumen height, the Haugh Unit and the yolk and albumen index decreased linearly as the levels of guava extract in the diet increased. The diameter of the albumen was higher with the use of 0.48% of guava extract in the diet. The yolk color was affected by the guava extract, presenting a darker color with 0.50% of guava extract in the diet. It was concluded that the guava extract used as an antioxidant additive does not improve the performance and egg quality of Japanese quails.

“…Resultados similares, foram relatados por Rizzo et al (2010), que utilizaram misturas de extratos vegetais em dietas para frangos de corte, inclusive os testados nesta pesquisa, e relataram que estes não influenciaram as variáveis de desempenho. Do mesmo modo, Freitas et al (2013) trabalhando com extratos de mangas para poedeiras comerciais com 40 semanas de idade, observaram que não houve diferença significativa no consumo de ração das aves e consequentemente o desempenho não foi afetado.…”

Effect of organic acids and essential oils on the performance of replacement pullets from their eighteenth to the seventeenth weeks of age

The study aimed to evaluate the effect of organic acids and the combination of organic acids and essential oils on performance of replacement pullets hens. 360 animals from Hy-Line Brown lineage with eight weeks of age were distributed in a completely randomized design with four treatments and ten replicates. The experiment lasted 63 days. The treatments (diets) were: Treatment 1 - negative control (no growth promoter); Treatment 2 - positive control (with growth promoter); Treatment 3 – basal ration + organic acids; Treatment 4 – basal ration + organic acids + essential oils. The variables evaluated were the initial and final weights, weight gain, accumulated consumption and feed conversion. There was no significant effect of treatment on any of the investigated parameters. It was concluded that the inclusion of organic acids or a combination of acids and essential oils do not affect the productive performance of replacement pullets.
