The objective of this study was to evaluate the substitution of maize by corn germ meal in diets for european laying quails. A total of 120 female quail of the 107 - day - old European pedigree, distributed in a completely randomized design with three treatments and eight replicates per treatment were housed in 24 metal cages representing an experimental plot with 5 birds per plot. The parameters evaluated were: number of eggs per bird housed, egg weight, laying rate, mean daily feed intake and feed conversion per egg mass in two production cycles, each of 28 days of egg collection. In the first laying cycle, no statistical differences were observed for the number of eggs per bird housed, posture rate and average daily feed consumption, however, there was an increase in egg weight and improvement in feed conversion. In the second production cycle, no statistical differences were observed for the number of eggs per bird housed and consumption of daily ration, but egg weight, egg laying rate and feed conversion improvement were observed. It was concluded that the substitution of maize by corn germ meal in diets for European quails up to 100% increases the production rate and egg weight and improves the feed conversion rate of the birds.

(2022-10-04) Pereira, Ruth Simão; Viana, Girlene Fábia Segundo; http://lattes.cnpq.br/3338076933519392; http://lattes.cnpq.br/9492033404642705
Arenaeus cribrarius, is a species of swimming crab of the Portunidae family of potential commercial value. This study aimed to analyze the stomach content of A. cribrarius specimens, collected at the mouth and surf zone of Jaguaribe Beach, Itamaracá-PE Island, in order to provide information on the composition of the natural diet of the species, as well as the characterization of their eating habits. The crabs analyzed were derived from the accompanying fauna of fish collections carried out through fishing with trawl of 20 m long, 1.5 m high and 5 mm mesh opening, carried out between July 2019 and January 2021. Two points were selected for the material collection: 1) Surf zone and 2) River mouth. For each point were performed two trawls with an interval of three minutes, once a month at low tide. After the collection, the crabs were transported to the Bentos laboratory (LABENTOS) of UFRPE/ UAST to perform the analyzes. After screening, the stomachs were removed from the visceral cavity and classified, performing prior to the withdrawal of the stomachs, a visual analysis, in order to identify the presence of oil stains in the internal whether the opening of the stomachs for identification of food components and qualitative-quantitative analyzes. From the analysis of the stomach contents of 64 specimens, 18 items of the diet of A. cribrarius distributed in the surf zone and mouth of this region were identified. The results obtained through the methods of points and frequency of occurrence, indicate that Crustacea and Osteichthyes were the most preferred items for both points of the species. For the male and female category, Crustacea was predominant, with overlapping of the other items. For the adult and juvenile category of the surf zone Crustacea and Osteichthyes were the most consumed by adults and only Crustacea for juveniles; for the mouth the item Crustacea was the most consumed for the area category. For the collection points (breaking zone and mouth) the food preference of the species is given by the items Crustacea followed by Osteichthyes, a factor probably associated with the proximity between the points and the high availability of these resources in the environment. For both seasonal periods in the analyzed points, Crustacea was the most intensely consumed item, followed by secondary items that overlapped in both periods and for both methods used. Significant differences were observed for the categories female and male, adult and juvenile seasonality. Even in small amounts, when compared to the other items, the presence of MPs in the stomachs of A. cribrarius presented significant frequency in the stomachs, suggesting that the species was exposed to remnants of human activity on Jaguaribe beach. The presence of oily substances in the external structures of the animals and their absence in the stomachs and other internal organs were not detected throughout the material analysis; data showed that there were no changes in the feeding of the species present in that locality after this episode

Exigência de lisina digestível para codornas europeias (Coturnix coturnix SP) em postura
(2019) Severo, Teofilo Izidio de Morais; Holanda, Marco Aurélio Carneiro de; http://lattes.cnpq.br/9825474552364226; http://lattes.cnpq.br/9304005643651714
An experiment was carried out to evaluate the productive performance of European quails (Coturnix coturnix sp) in the production phase, fed diets containing different levels of digestible lysine. A total of 175 female, 65 day age female quail were randomly distributed in a completely randomized design with five treatments and five replicates per treatment, housed in 25 metal cages, each representing an experimental parcel with seven birds per parcel. The birds were fed the experimental rations containing 1.177, 1.217, 1.317, 1.417, 1.517% digestible lysine in each treatment and their respective replicates. The parameters evaluated were: number of eggs produced in period, laying rate, mass of eggs produced, feed intake in period, lysine intake, feed conversion per dozen and feed conversion by mass. Statistical analysis was performed for analysis of variance and, in case of significance, a regression analysis was performed. Significance was observed for egg quantity in period and posture rate with quadratic behavior, indicating higher production for the best level of digestible lysine, being 1.23%, for feed intake and lysine intake was observed increasing linear behavior and for conversion feed per dozen and by mass were observed quadratic behaviors indicating better feed conversion index when the optimal inclusion level was 1.33% and 1.404% of digestible lysine in the diet, respectively. Concluded that the requirement of digestible lysine in diets for European quails (Coturnix coturnixsp) in the production stage created in environments with high temperature and low relative humidity is 1.404% corresponding to a daily intake of 421.20 milligrams of digestible lysine.

A nutrição apropriada é um dos quesitos mais importantes para a obtenção de um melhor desempenho dos animais, levando em consideração o valor nutritivo do alimento, como as exigências e a capacidade de benefício do consumo. O estágio supervisionado obrigatório (ESO) foi realizado na empresa Nutri Nordeste Nutrição Animal localizada no km 81,2 da BR 408, zona rural de Paudalho - PE, durante o período de 14 de novembro de 2022 a 11 de janeiro de 2023, totalizando 330 horas, sob orientação da professora Mônica Calixto Ribeiro de Holanda e supervisionado pelo Zootecnista e Médico Veterinário Alberto Gonçalves da Fonte. Dentre as atividades desenvolvidas durante o ESO, realizou-se um estudo de mercado em lojas agropecuárias de alguns municípios do sertão pernambucano. Neste estudo foi feito uma planilha para coletar informações, como produtos vendidos, peso, preço de compra, preço de venda, volume de venda mensal e fabricante. Com a coleta das informações foi possível realizar um cadastro que permitisse avaliar a abertura de novos mercados para os produtos da empresa na região do sertão. Em outra etapa do estágio foi possível acompanhar um representante comercial, para apresentação comercialização dos produtos da empresa, tais como a linha núcleos, linha rações para equinos, suínos, aves, coelhos, camarões, e linha de suplemento mineral e sal mineral.
