| ABSTRACT The influence of seasonality and the training and implementation of good dairy farming practices on raw milk production and quality was evaluated on dairy farms in Minas Gerais State, Brazil. The physico-chemical composition, somatic cell count (SCC) and total bacterial count (TBC) were determined in 3,096 milk samples collected from bulk tanks originated from 43 dairy farms over a three-year period and correlated with key climatic factors. The recommended milking management practices were applied through a training program and correlated with the seasonal data in three stages: I) prior to training (dry period); II) 48 days after the training (transition period); III) 96 days after the training (rainy period). In the first stage, a diagnosis of... |

| A stochastic capital budget was used to analyze the effect of net metering policies and carbon credits on profitability of anaerobic digesters on dairy farms in Pennsylvania. We analyzed three different farm sizes—500, 1,000, and 2,000 cows—and considered the addition of a solids separator to the project. Results indicate that net metering policies and carbon credits increase the expected net present value (NPV) of digesters. Moreover, the addition of a solids separator further increases the mean NPV of the venture. In general, the technology is profitable only for very large farms (1,000+ cows) that use the separated solids as bedding material. |

| 稲発酵粗飼料（以下，稲WCS）は，国内飼料自給率の向上や休耕田の解消といった利点があり，今後のわが国の農業の発展において期待されている．一方で乳量低下・疾病増加など稲WCSの品質が原因と考えられる負の影響について一部の導入農家から声が挙がっている．そこで本研究では，稲WCSを導入後乳量低下などが生じた酪農家を対象として調査を行い，月別の乳量・体細胞数の推移をみるとともに，稲WCS導入後の損失額の算出を試みた．調査の結果，搾乳牛中に“稲WCS給与牛”の割合が増加するにつれて，乳量の減少・体細胞数の増加がみられた．乳量の減少に伴う農家の損失額は年間で搾乳牛１頭当たり22〜37万円程度になった． Rice Whole-Crop Silage (RWCS) has some benefits such as the improvement of domestic self-sufficiency feed rate and the solution of fallow fields, and it has expected to be contributing to the development of Japanese agriculture in the future. On the other hand, the farmer who had introduced the RWCS considered that the RWCS causes negative effects; a decreasing in milk yield and an increasing in disease of cow. In this study, we researched on one dairy farm which... |
