| In many areas of the United States, dairy and livestock farmers are facing lawsuits due to a variety of externalities, such as odor and other forms of non-point source pollution, caused by Confined animal feeding operations (CAFO's). Complaints include: general illness, unpleasant odor, headaches, and property devaluation. However, state and national law requires all CAFO's to have some form of waste storage facility. These facilities, mainly lagoons, increase the potential of pollution and run-off into streams and other water sources. As a result, large producers are beginning to install anaerobic digestive (A.D.) systems, which are a new form of waste management practices that reduces negative environmental effects. Therefore, the purpose of this... |

| The increasingly stringent conditions underlying Swiss dairy production demand sustainable milk production systems that are economically optimized but also meet the ecological requirements of society. To determine such systems, a comparative-static LP model was constructed at farm level. Realistic production systems are reproduced in the model by means of binary variables. An Life Cycle Assessment (LCA) was integrated into the model to determine the environmental impacts of the farm. To this effect, the internal farm influences on production are illustrated in detail. An initial application of the model, in which a comparison of different income-optimized production systems was carried out, revealed some goal conflicts between economics and ecology.... |

| The objective of this work was to evaluate hematological, biochemical and ruminant parameters for diagnosis and treatment of the left displaced abomasum (LDA) in dairy cows, in the Plateau Region of Rio Grande do Sul, Brazil. Ruminant fluid, blood and urine samples were collected from 20 cows suffering LDA and from 20 healthy cows (control). The cows with LDA showed lower values of daily milk production, body weight and corporal condition score. The use of pH reagent strips showed to be functional in the field, when compared to a digital pH meter. Ruminant dynamics was damaged in cows affected by LDA, as it was evidenced by the higher reduction time of methylene blue. Serum values of lactate, beta-hydroxybutyrate, urea, albumin, free fatty acids and... |

| ABSTRACT The objective of this study was to evaluate the effects of different lipid sources in diets for lactating cows on milk yield and composition, conjugated linoleic acid (CLA) content, and fatty acid profile in the milk fat. Five primiparous Holstein cows were distributed in a 5 × 5 Latin square design. Treatments were: control (no lipid addition) and four other diets containing different lipids sources - ground raw soybean, cottonseed, soybean oil, and calcium salts of soybean fatty acids (CSSFA). The greater milk yield (kg/day) and milk lactose (g/kg) and solids non-fat (g/kg) contents were obtained with the animals fed diets with CSSFA. Regarding the fatty acid profile in the milk fat, the diets with CSSFA and ground raw soybeans produced the... |

| In developed countries, intensive grazing has been related to water pollution. The results of several projects carried out on a volcanic soil of the Osorno soil series on beef grazing production systems have shown that grazing management did not increase total nitrogen (N) and phosphorus (P) transfer and losses. Due to the high water infiltration capacity of the soil, runoff was <1% of total drainage, therefore, N and P losses in runoff were small. Nitrogen leaching losses were high (3 up to 71 kg N ha-1 yr-1). Nitrogen loss in runoff was mainly lost as DON (c. 50%) while N leaching losses were mainly as nitrate (c. 70%). Total P losses ranged between 1 and 22 g P ha-1 yr-1 and they increased with increasing field slopes. Phosphorus was mainly lost as... |

| Structural changes in the dairy industry such as the adoption of Total Mixed Rations in place of manufactured complete feeds and declines in milk production in the areas served by locals are bringing these cooperatives to a crossroads where they must decide who will be their core customer. The ramifications of this choice are increased through market segmentation which enables cooperatives to more precisely meet the needs of producer-members but simultaneously increases diversity among members and, potentially, among locals themselves. Survey results from 247 locals indicated small producers (cl00 cows) made up 80 percent of their clientele. The production practices of these producers appeared to lag significantly behind the innovators and large producers... |

| ABSTRACT The management of costs is used as a performance indicator by private companies in various sectors and, more recently, in public institutions, which offer free products and services to society. This article aimed to analyze the costs and revenues generated from the Production and Practice Labs (PPL) of Dairy Cattle and Dairy Products Processing from IFMG Campus Bambuí, to check the contribution of the revenues generated by these laboratories in reducing dependence on federal funds used to support these activities. The study was delimited with an investigation of the time series monthly revenues, costs and expenses of PPL analyzed from January 2012 to June 2014. The methodology used to determine the costs of Dairy Cattle production, was the... |
