Feeding plans with the use of glycerin for broilers

This study aimed to evaluate the effects of feeding plans with or without addition of glycerin, in different ages, on performance, carcass yield, litter moisture and footpad lesions of broiler chickens. 540 male Cobb broilers were utilized, distributed in a completely randomized design with six treatments (treatments consisted of the inclusion or not of glycerin in diets at all periods or only at different stages: 1 to 7, 8 to 21, 22 to 33 and 34 to 42 days), in six replicates of 15 birds each. Diets were provided ad libitum. At 42 days, the average weight, weight gain, feed intake, feed conversion, carcass yield, litter moisture and footpad lesions were evaluated. There was no effect (p> 0.05) of dietary plans on the performance variables. The feeding plans did not influence (p>0,05) the carcass and cuts parameters at 42 days. However, there was significant effect (p <0.05) of the dietary plans on litter moisture and plantar lesions. Effects were observed (p>0,001) for the feeding plans, were the highest and the lowest incidence of lesions were present in the birds that consume diets with and without addition of glycerin, in the period from 1 to 42 days of age, respectively.This study aimed to evaluate the effects of feeding plans with or without addition of glycerin, in different ages, on performance, carcass yield, litter moisture and footpad lesions of broiler chickens. 540 male Cobb broilers were utilized, distributed in a completely randomized design with six treatments (treatments consisted of the inclusion or not of glycerin in diets at all periods or only at different stages: 1 to 7, 8 to 21, 22 to 33 and 34 to 42 days), in six replicates of 15 birds each.

Displasia renal em cães: estudo retrospectivo (2008-2013)

Background: Renal dysplasia, which has been reported in some dogs and human patients, refers to a developmental disorder of renal parenchyma due to imperfect inductive interaction between the mesonephric duct and the metanephric blastemal. In dogs, the characteristic histological findings on which diagnosis is based include (1) persistent metanephric ducts surrounded by primitive mesenchyme, (2) fetal or immature glomeruli, (3) fetal or immature tubules, and (4) anomalous presence of interstitial fibrous tissue. The aim of this study was to report the major pathological and immunohistochemical features of nine young dogs necropsied with renal dysplasia.Cases: The necropsy files from the Laboratório de Patologia Veterinária (LPV) of the Universidade Federal do Mato Grosso (UFMT) were reviewed between the years 2008 and 2013. Dogs diagnosed with chronic kidney failure and macroscopic and histopathological renal lesions consistent with renal dysplasia were selected. Kidney fragments in paraffin blocks were cut and stained with hematoxylin and eosin and by immunohistochemistry (IHC) using anti-vimentin and anti-cytokeratin monoclonal antibodies. The staining was considered positive for the presence of at least one renal cell marked with brown cytoplasmic staining clear and unambiguous. A total of 787 necropsies of dogs were performed. Of these, 64 had a clinical diagnosis of chronic renal failure of which 9 were classified as renal dysplasia. The age of the dogs ranged from 3 months to 2 years. Clinical signs were characterized by anorexia and non-regenerative anemia in 88.9%, vomiting 66.7%, dehydration 55.6%, uremia 55.6%, convulsion 33.4%, abdominal pain 22.3% and diarrhea in 11.2% of cases. At necropsy the main macroscopic changes in the kidneys were external surface with pale staining, in 6 of 9 dogs necropsied. Additionally, 5 dogs, cystic cavities of various sizes from 0.1 to 5 cm in diameter, diffusely distributed in the renal subcapsular surface and cutting were observed. Of the 64 dogs with diagnosis of chronic renal failure, 14.06% had dysplastic kidney changes, characterized by dilatation of Bowman’s space, glomerular and tubular atrophy, immature glomeruli and tubules, lymphocytic interstitial inflammation and fibrosis. In the dogs with renal dysplasia, it was observed that the tubular structures showed marked glomerular labeling for vimentin. Moreover, the kidneys of normal dogs showed weak or absent for marking tubes and glomerular structures for vimentin, and strong staining for cytokeratin in tubular cells, glomerular cells and collecting ducts.Discussion: Renal morphological damage observed in these nine dogs less than two years old, that contained degenerative and inflammatory changes, fibrosis and glomerular atrophy, but mostly immature glomeruli and tubules were associated with atypical renal dysplasia. This condition develops when the urethral diverticulum and metanephric blastoma not properly form in the embryonic stage, resulting in abnormal metanephric differentiation and formation of structures that do not recapitulate the normal nephrogenesis. Abnormal kidney function in young animals caused chronic renal failure resulting in death. The results of immunohistochemical observed in this study can complement the diagnosis of renal dysplasia. The morphological normality can be observed in the proportion of mesenchymal and epithelial tissue in the different structures of the kidney by staining with anti-cytokeratin and anti-vimentin. In the present study, there was moderate to strong labeling of vimentin in glomerular and tubular structures being dysplastic kidney would be expected to occur in normal dogs predominant staining with cytokeratin. Based on the clinic, pathological and immunohistochemical findings it is concluded that the animals developed renal dysplasia

Productive features of broiler chickens in hot weather: effects of strain and sex

The objective of the present study was to evaluate the performance of broiler strains (Cobb 500, Ross 308, and Hubbard Flex) in hot weather. Environmental temperatures above thermal comfort trigger responses of the animals to maintain homeothermia, which negatively affects productive performance. A total of 2,160 chicks of both sexes, were distributed in an experimental design that was completely randomized in a factorial arrangement of 3 × 2 (strains and sexes) with six replicates of 60 birds each. Feed intake (FI), live weight (LW), weight gain (WG), and feed conversion (FC) were analyzed at periods of 1–7, 1–21, 1–28, 1–42, and 1–49 days old. At 42 and 49 days old, the carcass weight (CW), carcass yield (CY), breast yield (BY), thigh yield (TY), and drumstick yield (DY) were analyzed. The strains differed in LW and WG in most periods, especially for Cobb broilers in the pre-start period (1–7 days) and Hubbard broilers in the last two periods (1–42 and 1–49 days). Except for the pre-initial stage, which there was no influence of the strains on FC, the Hubbard broilers showed the best FC, at 1–49 d, similarly to Cobb broilers. Regardless of strain, the males showed superior performance to that of females. At 42 d, the Cobb broilers showed a superior BY to that of the other strains, presenting better TY than did the Ross and Hubbard strains. At 49 d, the Cobb and Ross strains showed the best BY, with the Hubbard strain having the greatest DY. Males showed higher values in cut yields, except in the BY in which females showed better results

NÍVEIS DE PROTEÍNA PARA FRANGAS SEMIPESADAS NO PERÍODO DE UMA A DEZOITO SEMANAS DE IDADE

Desenvolveram-se dois experimentos com o objetivo de avaliar diferentes níveis dietéticos de proteína bruta para frangas semipesadas. No primeiro experimento, as aves com dois dias de idade foram alimentadas até seis semanas com dietas contendo sete níveis de proteína (14%, 15%, 16%,17%, 18%, 19% e 20%) e com 3,0 Mcal de EM. No segundo experimento, a alimentação das aves constitui de dietas contendo quatro níveis de proteína (14%, 15%, 16% e 17%) e 2,9 Mcal de energia metabolizável da sétima a décima oitava semana. Após esse período, avaliou-se o desempenho produtivo dessas aves, no período de vinte e seis a trinta e oito semanas de idade. De uma a seis semanas de idade, o nível de 20% de PB proporcionou melhor desempenho. No segundo experimento, houve efeito significativo para o consumo de proteína e ganho de peso (efeito linear crescente) e efeito linear decrescente para conversão alimentar e eficiência protéica. Os níveis de proteína na fase de recria não influenciaram as variáveis avaliadas na fase de produção. Apenas houve efeito linear crescente para peso da casca. Com isso pode-se concluir que, para o período de sete a dezoito semanas de idade, a utilização de um nível de 14% de proteína bruta não afeta o desempenho das aves na fase de produção. PALAVRAS-CHAVES: Aves, cria, produção de ovos, recria e qualidade do ovo

Compreensão acerca dos fatores de risco de lesão por pressão em idosos internados em unidade de terapia intensiva

The aim of this study is to identify and analyze the main risk factors for pressure injuries related to hospitalization in the Intensive Care Unit. This is a bibliographical review of exploratory, quantitative and qualitative scientific literature. To select the sample, a search was made of the electronic databases LILACS and BDENF, from which a careful analysis was carried out, enabling the selection of twenty articles to be used to identify the risks of pressure injury in the elderly in the intensive care unit. The data was collected between March and May of this year. It is understood that there is a high probability of PPI developing in elderly patients after 60 years of age. The average length of hospitalization and pathologies such as hypertension and diabetes mellitus are key factors in the appearance of PI. According to the publications researched, it can be concluded that PPLs are a problem in hospital units that care for critically ill patients due to the permanent or temporary reduction in motility that exists in many cases.El objetivo de este estudio es identificar y analizar los principales factores de riesgo de las lesiones por presión relacionadas con la hospitalización en la Unidad de Cuidados Intensivos. Se trata de una revisión bibliográfica de la literatura científica exploratoria, cuantitativa y cualitativa. Para seleccionar la muestra, se realizó una búsqueda en las bases de datos electrónicas LILACS y BDENF, a partir de la cual se llevó a cabo un cuidadoso análisis que permitió seleccionar veinte artículos para identificar los riesgos de lesiones por presión en ancianos en la Unidad de Cuidados Intensivos. Los datos se recogieron entre marzo y mayo de este año. Se entiende que existe una alta probabilidad de que se desarrolle una IPP en pacientes ancianos después de los 60 años. La duración media de la hospitalización y patologías como la hipertensión y la diabetes mellitus son factores clave en la aparición de la IPP. Según las publicaciones investigadas, se puede concluir que las IPP son un problema común en las unidades hospitalarias que atienden a pacientes críticos debido a la reducción permanente o temporal de la motilidad que existe en muchos casos.Este trabalho tem como objetivo identificar e analisar os principais fatores de risco para lesão por pressão, relacionados a internação em Unidade de Terapia Intensiva. Trata-se de uma revisão bibliográfica em literatura científica exploratória, quantitativa e qualitativa. Para a seleção da amostragem foi feita uma busca a partir dos bancos de dados eletrônicos LILACS e BDENF, a partir disso foi realizada uma análise criteriosa que possibilitou através de uma leitura a seleção de vinte artigos para serem utilizados na identificação dos riscos de lesão por pressão em idosos na unidade de terapia intensiva. Os dados foram coletados entre os meses março a maio deste ano. Entende-se uma alta probabilidade de crescimento de LPP em pacientes idosos após 60 anos de idade. O tempo médio de internação e as patologias como hipertensão arterial e diabetes mellitus apresenta-se como fator primordial ao aparecimento de LPP. De acordo com as publicações pesquisadas, conclui-se que as LPP são agravos presentes em unidades hospitalares que cuidam de pacientes críticos devido a redução permanente ou temporária de motilidade existente em muitos casos. &nbsp
