Nowadays, an important and interesting alternative in the control of tick-infestation in cattle is to select resistant animals, and identify the respective quantitative trait loci (QTLs) and DNA markers, for posterior use in breeding programs. The number of ticks/animal is characterized as a discrete-counting trait, which could potentially follow Poisson distribution. However, in the case of an excess of zeros, due to the occurrence of several noninfected animals, zero-inflated Poisson and generalized zero-inflated distribution (GZIP) may provide a better description of the data. Thus, the objective here was to compare through simulation, Poisson and ZIP models (simple and generalized) with classical approaches, for QTL mapping with counting phenotypes... |

This was a retrospective cohort study using data from the insurance scheme provided by the Japanese Mutual Aid Association (NOSAI). The population of interest comprised all cattle born on NOSAI-client farms in the Japanese prefecture of Hokkaido, Japan for the period 1 April 2005-31 March 2009. The outcome of interest was whether or not at least one calf was stillborn, had died during delivery or died during the first 24 hours of life for a given calving event, termed first 24h mortality risk. A mixed-effects logistic regression model was developed to identify explanatory variables associated with first 24h mortality risk. The final data set comprised details of 1,281,737 calving events on a total of 5172 dairy herds from 19 NOSAI branches located... |

A study was carried out to assess the effect of mixed infection of Trypanosoma vivax and Fasciola spp. in an intensively managed dairy farm. Twenty lactating Friesian cows were screened, 25% (5/20) had concurrent infections of T. vivax and Fasciola spp., while 20% (4/20) had mixed infections of T. vivax and strongyle infection, 15% (3/20) had mixed infections of Theileria mutans and strongyle infection. Only 10% (2/20) has single infection of T. vivax and T. mutans respectively. Anemia, submandibular edema, reduce milk production emaciation and epiphora are the major clinical signs presented by the animals. |

To help Americans meet nutritional requirements while staying within caloric recommendations, the 2005 Dietary Guidelines for Americans encourage consumption of fruits, vegetables, whole-grain products, and fat-free or low-fat milk or milk products. This report provides one view of the potential implications for U.S. agriculture if Americans changed their current consumption patterns to meet some of those guidelines. For Americans to meet the fruit, vegetable, and whole-grain recommendations, domestic crop acreage would need to increase by an estimated 7.4 million harvested acres, or 1.7 percent of total U.S. cropland in 2002. To meet the dairy guidelines, consumption of milk and milk products would have to increase by 66 percent; an increase of that... |

We explore and investigate Japanese dairy markets. We first provide an overview of consumer demand and how it evolved after World War II. Using historical data and econometric estimates of Japanese dairy demand, we identify economic, cultural, and demographic forces that have been shaping consumption patterns. Then we summarize the characteristics of Japanese milk production and dairy processing and policies affecting them. We next describe the import regime and trade flows in dairy products. The analysis of the regulatory system of the dairy sector shows how its incentive structure affects the long-term prospects of various segments of the industry. The paper concludes with policy recommendations of how to reform the Japanese dairy sector. |

One objective of the NAHMS Dairy '96 Study was to assess dairy producer awareness of Johne's disease, estimate national and regional herd-level prevalence of Mycobacterium paratuberculosis infection, estimate economic losses due to Johne's disease on dairy operations, and describe use of recommended preventive measures on U.S. dairy operations. Data were collection from U.S. dairy operations with at least 30 milk cows in 20 states representing 79.4 percent of U.S. dairy cows via questionnaires administered to dairy managers and blood samples collected from milk cows by Veterinary Medical Officers and Animal Health Technicians. Sera were tested for antibodies to M. paratuberculosis using a commercially available ELISA. Results showed lack of... |

The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. Data on digital dermatitis were collected during the second phase as Federal or state Veterinary Medical Officers (VMO's) or Animal Health Technicians (AHT's) contacted producers from February 20 through May 24, 1996 to complete a questionnaire.

Combined balance sheets and operating statements were used to develop benchmark financial ratios for dairy marketing cooperatives. Data from 291 cooperatives were summarized for five types of dairy cooperatives, then by three types and three size combinations. Both type and size of cooperative made differences in most of the 16 financial ratios calculated as well as in the common size balance sheets and operating statements. |

Over the past 10 years, the growth of nontraditional retail food outlets has transformed the food market landscape, increasing the variety of shopping and food options available to consumers, as well as price variation in retail food markets. This report focuses on these dynamics and how they affect food price variation across store format types. The differences in prices across store formats are especially noteworthy when compared with standard measures of food price inflation over time. Over the past 20 years, annual food price changes, as measured by the Consumer Price Index (CPI), have averaged just 3 percent per year, while food prices for similar products can vary by more than 10 percent across store formats at any one point in time. Since the... |

This bulletin provides an overview of trends in cropland values in Canada. Cropland values are a major component of farm wealth which, together with income can be used as a measure of the economic well-being of farm households. Cropland values are provided for a 3-year period, 2005-2007, for each province and farm type (beef, hog, poultry and egg, dairy, grain and oilseed, potato, greenhouse, and fruit and vegetable farms). |

The EU dairy industry faces an unprecedented level of change. The anticipated removal of milk quotas and the move to a less restricted global trade environment will provide the industry with both opportunities and challenges. The primary challenge will be the need for the industry to deal with more volatile prices. Active management of the risks associated with these more volatile prices will help to place the industry in a more competitive position. However this will require the industry and policy makers to embrace a new set of tools. For example the US dairy industry has been much more active in the management of risk and lessons from their experience provide a valuable insight into which tools may be more appropriate in an EU context. |
