Comparação da eficiência reprodutiva da inseminação artificial cervical e da inseminação artificial pós-cervical em suínos

O presente trabalho tem como objectivo comparar os resultados reprodutivos de uma nova técnica de inseminação artificial (IA), inseminação arlificial pós cervical (IPC) com a técnica de inseminação artificial cervical (IC), e verificar a viabilidade técnica e económica da introdução desta nova téc1úca numa exploração de suínos. Para a realização do trabalho, utilizaram-se 100 porcas resultantes de cruzamentos com as seguintes raças: Landrace, Large White e Chinois e 2 varrascos resultantes do cruzm11ento de Pietrain e Dmoc. Todas as porcas eram multíparas, sendo distribuídas de fonna aleatória pelas duas téc1úcas. Foram utilizadas doses de sémen do mesmo varrasco e do mesmo lote de recolha, nas duas técnicas, contendo um número de espem1atozóides (SPZ) por dose de 4 * 1 09 (I C) e 2 * 1 09 (IPC). Não foram observadas diferenças significativas entre tratamento.s para os principais parâmetros reprodutivos estudados entre as duas técnicas, sendo: a taxa de fertilidade de 82% para (IC) e 88% para (IPC); a média de leitões nascidos vivos foi 10,9 para (I C) e 1 I ,3 para (IPC), a média de leitões nascidos mortos foi 1,2 para (TC) e 1,0 para (IPC) e a média de leitões mumificados foi 0,4 para (IC) e 0,7 para (IPC). Em termos económicos a inseminação artificial pós cervical pode permitir obter uma receita líquida superior quando comparada com a inseminação artificial cervical .. Estas receitas superiores devem-se à necessidade de um número inferior de espermatozóides por dose, sendo necessário um menor número de varrascos, permitindo trabalhar apenas com reprodutores de maior potencial genético. The aim of the present study is the comparison of reproductive results with the use of one new technique of artificial insemination (AI); post cervical insemination (IPC) with the technique of cervical insemination (IC). and check technical anel economical viability of introducing this new teclmique in a swine fam1. For the accomplislm1ent of this work we have used 100 sows resul1ing from the cross of Landrace, Large White and Chinois races and two boaTs resulting from the cross of Pietrain and Duroc. All the sows had one or more farrows, they've been distri buted randomly by the two lA techniques. We have used sperm doses from the same boar and the same lote in the two teclmiques, containing the same mm1ber of spermatozoa per dose of 4*1 09(IC) and 2* 1 09(IPC). No significant differences were noticed between the treatments for the main reproductive parameters studied, being: the fanowing rate of 82% (IC) and 88% (IPC), the litter size of 10,9 (IC) and 11,3 (IPC) piglets bom per inseminated sow, 1,2 (IC) and 1 ,O (IPC) born dead piglets and 0,4 (I C) and 0,7 (IPC). In economical terms the IPC teclmique, may reach a lúgher profits compared with the IC teclmique. These higher profits are dueto the need of a smaller number of spermatozoa per dose, being needed a smaller number of boars, what allows us to work only with boars of higher genetic potential

Traditional alimentary products: purchase habits and honey consumption

Este estudo tem como objectivos conhecer o perfil do consumidor do mel e descrever os seus hábitos de consumo e compra. Foi elaborado um estudo quantitativo que teve como base a construção de um questionário, que foi aplicado a 172 indivíduos do Distrito de Bragança. Através da análise descritiva dos dados faz-se a caracterização da amostra e descrevem-se os hábitos de consumo e compra do mel. Participaram neste estudo 172 indivíduos, dos quais 41,9% são do sexo masculino e 58,1% são do sexo feminino. Verificou-se que a esmagadora maioria é consumidor de mel (94,8%), prefere o mel da região porque está mais disponível, é mais saboroso e tem qualidade (70,9%). A principal forma de utilização do mel é combinado com outros alimentos (60,5%), o local preferido para a sua compra é junto do produtor (51,7%) e o factor que mais pesa na decisão de compra é o paladar (52,3%). To determine the honey consumer’s profile and to describe your purchase and consume habits are the objectives of this study. A cross-sectional survey was carried out in a probabilistic sample including 172 individuals of the Braganza region population. After, data descriptive analyses is done characterization of the sample and are described purchase and consume habits of the inquiry. In this study participated 172 individuals, of which 41,9% are male and 58,1% are female. It was verified that the smashing majority is honey consumer (94,8%), they prefer the national honey because it is more available, it is tastier, it is quality and it is trustworthy (70,9%). The main form honey use is mixed with other foods (60,5%), the favorite place for the honey purchase is near the producer (51,7%) and the factor that more it weighs in the purchase decision this product is the palate (52,3%)

Augusta dos Anjos e seu desejo de morte ou como tornar a vida viável

This article revisit the trauma theory as organized in the studies of Freud and Ferenczi, identifying points of confluence and friction between them. Therefore we present a clinical case aiming to clear this notion, which is known the importance of clinical contribution to the theoretical development of the psychoanalysis.Neste artigo revisitamos a teoria do trauma, tal como organizada nas obras de Freud e Ferenczi, tangenciando pontos de confluência e de fricção entre elas. Para tanto, apresentamos um caso clínico objetivando clarear essa noção, sabida que é a importância da contribuição da clínica para o desenvolvimento teórico de nossa disciplina

Maternal exposure to mixtures of dienestrol, linuron and flutamide. Part I: Feminization effects on male rat offspring

Exposure to endocrine-disrupting compounds (EDCs) during pregnancy can result in negative health effects in later generations, including sex changes and feminization. The present study assessed the feminization effects on male offspring rats of three EDCs: Dienestrol (DIES), Linuron (LIN), and Flutamide (FLU). Sexually mature female rats were exposed from gestation day (GD) 6 until postnatal day (PND) 21 to: 0.37, 0.75, 1.5, 3.12 or 6.25 μg/kg/day of DIES, 1.5, 3, 6, 12.5, 25 or 50 mg/kg/day of LIN, 3.5, 6.7, 12.5, 25 or 50 mg/kg/day of FLU, and the following mixtures: FLU + DIES (mg/kg/day+μg/kg/day), 3.5 + 0.37, or 3.5 + 3, 25 + 0.37, or 25 + 3; FLU + LIN (mg/kg/day + mg/kg/day), 3.5 + 12.5, or 25 + 12.5; and DIES + LIN (μg/kg/day + mg/kg/day), 0.37 + 12.5, or 3 + 12.5. Anogenital distance (AGD), nipple retention (NR) and cryptorchidism were evaluated. FLU produced a decrease of AGD, an increase of NR, and an increase of cryptorchidism at the highest dose. None of these three endpoints were significantly affected by LIN or DIES treatments alone. Combinations of FLU + LIN and FLU + DIES increased NR, and decreased AGD, while DIES + LIN did not produce any effects in male pups. Results show that FLU is able to induce feminization in male pups, while binary combinations of LIN and DIES did not modify the effects produced by FLU.</p

Hibiscus sabdariffa L. in meat sausage and its effect on the physicochemical, nutritive, microbiological characteristics and sensory acceptance

Recently, importance has been given to improving the quality of meat products by adding functional ingredients. Therefore, the effect of adding Hibiscus sabdariffa L. (jamaican flower) on the physicochemical, microbiological properties and sensory acceptance in a sausage type sausage was evaluated, using a completely randomized design, with 0.0% addition levels, 5.0%, 7.0%, and 9.0% of H. sabdariffa L. in treatments F0, F5, F7 and F9 respectively. It was observed pH below 4.76 and acidity above 0.9%, which could inhibit bacterial growth. Depending on the increase in Jamaica, the fat decreased, and the fiber increased, without affecting the ash concentration. In F5 and F7 the highest protein values were obtained and although F9 has 14.09% it is still acceptable. The microbiological parameters resulted in what is permissible by the NOM. There were no differences (P <0.05) in the level of liking of F0, F5, F7, F9 and FC (commercial formulation), qualifying them as "I like". It is concluded that F9 is a formulation with functional characteristics, on the basis that it obtained the lowest levels of fat and higher fiber content, which could positively influence the health of consumers
