Perfil bioquímico das galinhas poedeiras na região de Araçatuba-SP

The establishment of reference values is extremely important for successful diagnosis and treatament. Considering that in most species the serum chemistry profile is influenced by race, climate and management, we decided to determine the values of aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid, creatinine, creatine kinase (CK), phosphatase alkaline (ALP), gamma-glutamyltransferase (GGT), total protein (TP) and albumin of Dekalb hens in the region of Araçatuba - SP. All samples were processed soon after harvesting in an automatic biochemical analyzer calibrated and monitored with control serum levels I and II. The following confidence intervals were obtained: 44-65,5 U / L (AST); 18,4-21,2 U / L (ALT), 2.1-2.5 mg / dL (uric acid); 1.7 to 5.7 U / L (CK); CI 1.2-2.2 mg / dL (creatinine), 1276-1506 U / L (FA); 18-23,4 U / L (GGT); 27.12 to 29 g / L (PT), from 11.4 to 12.16 g / L (albumin).

The aim of this study was to evaluate the serum protein concentration in newborns fed with colostrum derived from healthy cows (n = 10), cows with subclinical mastitis (n = 10) and cows with clinical mastitis (n = 10). 30 Holstein cows were assigned to their respective groups according to macroscopic examination of colostral secretion, somatic cell count, CMT and presence of bacteria in colostrum samples. Blood samples of the calves were collected immediately after birth, at 24 and 48 hours after ingestion of colostrum. The total protein was measured by the biuret method and the concentrations of immunoglobulin A (IgA), immunoglobulin G (IgG), transferrin, albumin and haptoglobin was determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). No differences were obser- ved amongst groups in the concentrations of albumin, total protein and IgA. In animals from cows with subclinical and clinical mastitis haptoglobin concentrations were higher than those of healthy animals. The concentrations of IgG and transferrin were significantly lower in calves from cows with mastitis. We concluded that the ingestion of colostrum from infected and uninfected glands from cows with mastitis (GII e GIII) is unlikely to be an important contributor to the high rate of failure of passive transfer of immunoglobulins in calves.

Cultivation and bromatological analysis of the medicinal mushroom Ganoderma lucidum (Curt.: Fr.) P. Karst cultivated in agricultural waste

The objective of the study was to evaluate the production of two strains of Ganoderma lucidum on agricultural waste and carry out bromatological analyses of the basidiomata obtained from the cultivation. The experiment was carried out at the Mushroom Module at the School of Agronomic Sciences of the São Paulo State University (FCA/UNESP - Botucatu, SP, Brazil) and two strains were used (GLM-09/01 and GLM-10/02) which were cultivated on waste, oat straw, bean straw, brachiaria grass straw, Tifton grass straw and eucalyptus sawdust under two situations: with (20%) and without (0%) supplementation with wheat bran. All the waste was taken from dumps of agricultural activities in Botucatu-SP. Both treatments were carried out in 10 repetitions, totaling 200 packages. The mushrooms cultivation took 90 days. Next, the biological efficiency of the treatments and the bromatological analysis of the basidiomata were evaluated. The biological efficiency (BE) values (%) varied from 0.0 to 6.7%. In the mushroom bromatological analyses, the results ranged from 8.7 to 13.7%, from 2.0 to 6.7%, from 0.83 to 1.79% and from 38.8 to 54.5%, for total protein, ethereal extract, ash and crude fiber, respectively. Thus, we conclude that the substrates which presented the greater yield were the brachiaria straw, 20% in both strains tested (GLM-09/01 and GLM-10/02) and the bean straw, 20% in the strain GLM-10/02. The mushrooms showed high levels of ethereal extract, fibers and ashes and a low level of proteins.

Circulating leukocyte heat shock protein 70 (HSP70) and oxidative stress markers in rats after a bout of exhaustive exercise

A novel method to measure oxidative stress resulting from exhaustive exercise in rats is presented. In this new procedure we evaluated the erythrocyte antioxidant enzymes, catalase ( CAT) and glutathione reductase (GR), the plasma oxidative attack markers, reactive carbonyl derivatives (RCD) and thiobarbituric reactive substances (TBARS). Muscular tissue damage was evaluated by monitoring plasma creatine kinase (CK) and plasma taurine ( Tau) concentrations. Also, we monitored total sulphydryl groups (TSG) and uric acid (UA), and the level of the 70 kDa heat shock protein (HSP70) in leukocytes as a marker of oxidative stress. In the study we found a correspondence between erythrocyte CAT and GR activities and leukocyte HSP70 levels, principally 3 h after the acute exercise, and this suggested an integrated mechanism of antioxidant defense. The increase in levels of plasma Tau was coincident with the increasing plasma levels of CK and TBARS, principally after two hours of exercise. Thus tissue damage occurred before the expression of any anti-oxidant system markers and the monitoring of Tau, CK or TBARS may be important for the estimation of oxidative stress during exhaustive exercise. Furthermore, the integrated analyses could be of value in a clinical setting to quantify the extent of oxidative stress risk and reduce the need to perform muscle biopsies as a tool of clinical evaluation.

Digestão total e parcial de alguns componentes de dietas contendo diferentes níveis de casca de soja e Fontes de nitrogênio, em bovinos

Este experimento foi realizado para avaliar o efeito de dois níveis de casca de soja (CS) e de três fontes de nitrogênio sobre a digestão total e parcial aparentes no rúmen e nos intestinos. Seis novilhos Holandês x Zebu com idade média de 12 meses e 229 kg de PV foram fistulados no rúmen e no abomaso e distribuídos em quadrado latino 6x6 e alimentados individualmente ad libitum. O consumo e as digestibilidades totais e parciais dos nutrientes foram avaliados. Não houve efeito da fonte de proteína sobre o consumo, quantidades de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), fibra em detergente neutro (FDN) e da fibra em detergente ácido (FDA) no rúmen, no abomaso e nas fezes e sobre os coeficientes de digestibilidades destes componentes. O aumento, porém, do nível de casca de soja elevou os coeficientes de digestibilidade de todos os componentes estudados nos locais do trato digestivo, com exceção nos intestinos, onde o nível de casca de soja não afetou a digestão da PB, FDN e da FDA. Os resultados indicam que a casca de soja pode substituir tanto o milho como, parcialmente, a fração volumosa nas rações de ruminantes. A farinha de subproduto avícola e a amiréia podem substituir o farelo de soja nas rações de bovinos sem reflexos negativos sobre a digestão de seus componentes nutritivos.
