“…Coturniculture is the segment of the poultry industry responsible for raising, promoting, and managing quails (SIlVA et al, 2018), standing out from its modernization, followed by new production technologies, progressing from a subsistence to a technical activity, with positive results to investors (PAStoRE et al, 2012).…”

“…Besides favorable results, coturniculture has encouraging characteristics such as low initial investment and fast economic return, with quails being fast-growing birds with good feed conversion, early sexual maturity (35 to 42 days), and productive longevity (14 and 18 months), which requires small farming spaces (MURAKAMI & ARIKI, 1998;PAStoRE et al, 2012). In this context, quail farming plays an important social role, providing a source of income for family agriculture and small rural producers (SIlVA et al, 2018).…”

Location, distribution, and quantification of myenteric plexus neurons of the jejunum of quails fed with different levels of commercial Macleaya cordata extract

Coturniculture has been promising, progressing from a subsistence to a technical activity due to its quick production, low breeding investment, and rapid economic return. After the restriction of antimicrobials as growth promoters, some studies aimed to evaluate alternative products that would make the farming of healthy birds viable without impacting their performance, with commercial Macleaya cordata extract being one of these substitutes. The functions of the gastrointestinal tract are coordinated mainly by the enteric nervous system, and the myenteric plexus is responsible for the reflex control of contractile activities of the external muscles. Thus, this study located and demonstrated the distribution of the myenteric plexus, quantifing the total population of myenteric neurons (Giemsa+) and the subpopulation of myenteric nitrergic neurons (NADPH-d+), and evaluated the effects of commercial Macleaya cordata extract on these populations of quail jejunum neurons. A total of 240 one-day-old female laying quails were distributed into four treatments, with four repetitions of 15 birds each. The test groups (T1, T2, and T3) were treated with commercial Macleaya cordata extract throughout the experimental period using the following doses: T1 - test group, basal diet added with 150 ppm of the extract in the feed; T2- test group, basal diet added with100 ppm of the extract in the feed; T3 - test group, basal diet added with 50 ppm of the extract in the feed; and T4 - control group, basal diet with no added extract. The study included histological analysis, Giemsa+, and NADPH-d+ myenteric neuron staining. The results showed that the myenteric plexus is located between longitudinal layer fibers and in the transition region between the longitudinal and circular layers of the muscular tunic, with the myenteric population organized into ganglia and isolated in the region of neuronal fiber bundles. The commercial Macleaya cordata extract showed no quantitative changes in the myenteric Giemsa+ population and myenteric NADPH-d+ subpopulation, however, the groups that consumed the extract showed greater NADPH-d+ neuron activity compared to the control group, implying that the food remained longer in the intestinal lumen, therefore, enabling greater nutrient use and resulting in increased productive performance.

“…A criação de codornas se torna uma alternativa interessante para pequenos produtores pelo fato de possuir investimento e manutenção de baixo custo em relação às outras criações, utilização de pequena área para instalação e apresentando rápido retorno do investimento, a partir do segundo ano (Silva et al, 2018). Além disso, a atividade contribui para o fortalecimento da economia do agronegócio através da movimentação da cadeia produtiva deste segmento com consequente geração de renda.…”

Neste estudo apresenta-se uma conjuntura da produção de ovos de codorna no estado do Pará, a partir de uma análise do período de 2000-2019, utilizando dados secundários de série temporal de produção de ovos e quantitativo de cabeças de codornas, obtidos junto ao Banco de Dados do IBGE. Foram estimados o Quociente Locacional (QL) que indica a especialização de uma região em uma determinada atividade ou setor e o Coeficiente de Gini Locacional (CGL) que identifica a concentração espacial. Os resultados do estudo mostram que no período analisado a mesorregião Metropolitana de Belém perdeu força participativa na produção paraense colocando as mesorregiões Sudeste e Sudoeste Paraense com a maior concentração da produção do estado. Os municípios de Altamira, Paragominas e Santarém se apresentam como os maiores produtores de ovos de codorna do estado do Pará. Apesar disso, a produção de ovos de codorna paraense, nos últimos anos, se apresenta em declínio e redução das microrregiões especializadas, observando-se elevada concentração espacial.

“…Quail farming has been inserting into industrial poultry production as a profitable activity and with good prospects for development, through the introduction and breeding of European quails (Coturnix coturnix coturnix), driven by the significant growth in consumer market demand for quail meat (Pastore, et al, 2012;Silva et al, 2018). Among the factors that most influence the cost of quail production, feeding represents more than 70% of the total cost.…”

The objective of this study was to determine the chemical composition and energy value of passion fruit seed cake (PFSC) and to evaluate the inclusion of different levels of PFSC in the diets for quails on growth performance, carcass quality, litter quality, lipid stability of the meat, and economic viability. In the metabolism assay, 108 European quails of 21 days of age were used, being distributed in a completely randomized design with 3 treatments (one reference ration and two test rations with substitution of 20% and 40% of the reference ration by PFSC) and 6 replications of 6 birds each. It was observed that the apparent metabolizable energy corrected by the nitrogen balance (AMEn) determined in the ration with 20% PFSC (3876.17 kcal/kg DM) was higher than in the 40% (3469.00 kcal/kg DM). In the performance assay, 432 European quails from 7 to 42 days of age were used, being distributed in a completely randomized design with 6 treatments, consisting of a control diet and the others with increasing levels of inclusion of passion fruit seed (5, 10, 15, 20, and 25%), and 6 replications of 12 birds. It was observed that the inclusion of PFSC starting from 10% promoted increase FI and FC values, and increasing linear effect of these variables starting from 5% of inclusion. The PFSC did not affect the carcass characteristics and lipid oxidation of the meat. Regarding the litter quality, there was a linear increase in the pH values and worse economic indexes starting from the inclusion of 10% of PFSC. In conclusion, PFSC can be used up to the level of 5% in diets for meat quails from 7 to 42 days of age.
