Performance of Cultivars for Production of Green Corn in Different Planting Dates in Passos Region, MG

The aim of this work was evaluating the performance of several cultivars of green corn for consumption 'in natura' in different planting dates. The first planting date was on May 26th, and the others, every 40 days. The hybrids (treatments) were: AG-1051, Agroeste 1567, BM-3061, Prezoto-32D10, PL-6880, BX-1382 and GNZ-2004. The following characteristics were evaluated: production, commercial ears weight without husk, commercial ears number, commercial ears diameter and length, male flowering, plant height and height of ear corn insertion. The cultivars AG1051, Agroeste 1567 and BM 3061 presented the best results compared to the others and they should be used in green corn production for ` in natura' consumption in Passos County, MG.

Biological control of sheep parasite nematodes by nematode-trapping fungi: In vitro activity and after passage through the gastrointestinal tract

The main method used for the control of gastrointestinal nematodes in sheep production is the application of chemotherapeutic agents, which often lead to the selection of parasites resistant to given active principles. Biological control can be considered a promising alternative, contributing to an increase in the efficacy of verminous control. We determined the in vitro activity and in situ survival of the predatory fungi Arthrobotrys musiformis and Arthrobotrys conoides during passage through the gastrointestinal tract of sheep after oral administration of conidia in microencapsulated form and as a liquid in natura. Initial in vitro tests showed that both fungi were efficient in the predation of trichostrongylid L3 larvae present in the faeces of sheep naturally infected with gastrointestinal nematodes. The fungi presented high nematophagous activity, which was 99.3% for A. conoides and 73.7% for A. musiformis. A. conoides did not survive passage through the gastrointestinal tract under the conditions of the present experiment. On the other hand, A. musiformis was reisolated after administration in either microencapsulated or liquid form, suggesting that this species is a promising alternative for the control of nematodes in sheep since it survives without any protection (in natura). © Springer 2005.

Atividade antimicrobiana in vitro de extrato de Punica granatum L. sobre staphylococcus aureus isolado em leite bovino

Bovine mastitis is considered important disease causing major economic losses in dairy herds. Antimicrobial drug can promote resistance, chemical residues in food and environmental contamination. The purpose of this study was to evaluate the antibacterial activity in vitro of pomegranate extract on Staphylococcus aureus isolated from bovine milk, evaluate its antioxidant activity, and quantify levels of total phenols and fravonoides of the different extracts used. Aqueous extracts were used in nature and dry, from the peel of the fruit (EAC) and leaves (EAF). Additionally, it was evaluated the antioxidant activity (AA%), total phenols and flavonoids. Milk samples were inoculated, incubated, and the colonies were characterized as Staphylococcus aureus were adjusted to 1.0x106 UFC/mL in the 6 standard of the MacFarland scale. The sensitivity of the microbial isolates were determined in quintuplicate, in disk diffusion test. The minimum inhibitory concentration was determined by visible inhibition zone greater than 15mm. The results were evaluated by ANOVA, Tukey 5%, using the program SISVAR 5.3 - DEX/UFLA. Results implied that the aqueous extract from the bark of dried fruit was capable of inhibiting bacterial growth at concentrations of 3%. The other treatments only showed this activity, from the concentrations of 15%, 20% and 30% for dry EAF, in nature EAC and in nature EAF, respectively. Regarding the action antioxidant of dry EAC, was not correlated with total phenols and flavonoids. Probably other alkaloids substances present in the extract studied, may have been responsible for this activity. It is concluded that extracts of Punica granatum L., especially those obtained by the shell of the fruit, showed inhibitory activity against S. aureus, indicating your use potential for the control of bovine mastitis.
