Parâmetros ósseos de frangos de corte alimentados com rações contendo fitase e baixos níveis de fósforo disponível e proteína bruta / Bone parameters for broilers fed diets with phytase and low phosphorus and crude protein levels

Foram utilizados 504 pintos de linhagem comercial (Ag Ross 308) para frangos de corte de um dia de idade, distribuídos em 12 tratamentos com seis repetições. O delineamento experimental utilizado foi de blocos ao acaso em esquema fatorial 2x2x3, com dois níveis de fósforo disponível (0,45 e 0,34%), dois níveis de fitase (0 e 1200 FTU/kg) e três níveis de proteína bruta (22,5; 20,5 e 18,5%). A porcentagem de cálcio e fósforo nas tíbias foi influenciada significativamente pelos níveis de proteína e de fósforo na dieta com o uso da fitase. Os teores de matéria mineral nas tíbias apresentaram efeito linear com o uso da enzima e efeito quadrático com a ausência dela, apresentando maior valor com o nível de 22,5% de proteína na dieta. Já com os maiores níveis de fósforo houve efeito linear entre os níveis de proteína bruta na dieta e os pesos da matéria mineral nas tíbias, ou seja, quanto maior o nível de proteína, menor o peso da matéria mineral.

504 (five hundred four) 1 day old male chicks from a commercial broiler line (Ag Ross 308) were used, distributed in 12 treatments, with 6 replicates per treatment. The experimental design was casually blocked and treatments were organized in a 2x2x3 factorial arrangement: two available phosphorus levels (0.45 and 0.34%), two phytase inclusion levels (0 and 1200 FTU/kg) and three crude protein levels (22.5; 20.5 and 18.5%). Tibia calcium percentage was influenced by protein and phosphorus levels in the diet, when using phytase. Tibia ash levels showed a linear effect when enzymes were added and showed a quadractic effect without it, and the higher value was observed with 22.5% crude protein in the diet. With higher phosphorus levels a linear effect was observed between crude protein in the diet and tibia ash weights, as a higher protein level had lower tíbia ash weight.

Síntomas de vejiga hiperactiva en mujeres en fase gestacional y puerperal: ¿existe correlación entre los síntomas y la percepción de la calidad de vida? / Overactive bladder symptons in pregnancy and puerpery: Is there a relationship between the symptoms score and quality of life?

Introducción y objetivo: Los síntomas del tracto urinario bajo durante la gravidez pueden ser influenciados por factores, como adaptaciones hormonales, aumento de peso corporal y sobrecarga de presión por el útero grávido sobre la vejiga y el suelo pélvico. La propuesta fue evaluar la correlación de esos síntomas con la calidad de vida en las fases gestacional y puerperal. Material y método: Estudio prospectivo utilizando el Overactive Bladder Questionnaire Short Form (OABq-SF). Participaron 60 gestantes, edad media de 24 años (14–40), evaluadas durante el último trimestre gestacional y revaluadas 6 meses después del parto. El análisis estadístico correlacionó historia obstétrica, síntomas miccionales y calidad de vida con el método Spearman, utilizando el método de Pearson para la correlación del score de OABq-SF. Resultados: La media del score del OABq-SF durante la gravidez fue de 35,2, en tanto que 6 meses después del parto declinó a 15,0. Para la calidad de vida se verificó una media de 82,9 durante la gravidez y de 88,4 6 meses después del parto. La percepción de las pacientes fue del 55,02% (p=0,0001) durante la gravidez y del 36,01% (p=0,0046) durante el puerperio. La correlación clínica fue del 6,7%. Conclusión: Nuestro estudio demostró que a pesar de que los síntomas del tracto urinario bajo se encuentran presentes durante la gravidez, no hay correlación clínica en la percepción de las gestantes (AU)

Introduction and objective: During pregnancy, hormonal change, increase in the body mass index and the pressure caused by the enlarged uterus over the bladder and pelvic floor, are some factors involved in lower urinary tract symptoms (LUTS). This study was made to evaluate the correlation between pregnancy and delivery way with LUTS. Material and method: This open prospective study was carried out using the overactive bladder questionnaire short form (OABq-SF). A total of 60 patients enrolled this study. The mean age was 24 year, raging from 14 to 40 years. The patients were evaluated during the third trimester and 6 months after delivery. Statistical analysis of the OABq-SF scores was made using the Pearson method. Results: Mean OABq-SF score during pregnancy was 35.2 and 6 months after delivery decreased to15. Quality of life was 82.9 during pregnancy and increased to 88.4 at 6 month after delivery. Patient's perception, that is correlation, was 55.02 (p=0.0001) during pregnancy and 36.1% (p=0.0046). Clinical correlation index was 6.7%. Conclusions: Our study demonstrated that in spite of LUTS being more important during pregnancy, there is no significant clinical correlation in patient's perception (AU)

Desaleitamento de bezerros com emprego de soja integral extrusada na mistura iniciadora / Weaning of calves with utilization of extrused whole soybean in calf starters

Vinte bezerros foram submetidos, logo após a ingestäo de colostro, aos tratamentos: mistura iniciadora com farelo de soja (FS) ou soja integral extrusada (SIE) mais leite na forma líquida; e com FS ou SIE mais leite na forma em pó. Em todos os tratamentos o leite (na forma líquida ou em pó) foi retirado no 36º dia, quando os animais passaram a receber apenas as respectivas misturas iniciadoras. Do 7º ao 35º dia, os tratamentos com leite na forma líquida apresentaram maiores ganhos de peso, e aqueles contendo misturas iniciadoras com SIE resultaram em menores consumos de alimentos. Após a retirada do leite, do 36º ao 63º dia, ou considerando todo o período experimental (7º ao 63º dia), ocorreram maiores ganhos em alturas nas cernelhas nas dietas com leite na forma líquida. Níveis de glicose sangüínea e aspectos de desenvolvimento da mucosa do rúmen de animais abatidos e incidências de diarréias näo diferiram entre tratamentos. O uso de SIE para bezerros desmamados precocemente mostrou-se viável; todavia, o sistema de alimentaçäo com leite ministrado na forma em pó näo permitiu o desenvolvimento adequado dos animais
