| The aim of this study was to determine the prevalence of Toxoplasma gondii in cattle from the Northern and Midwestern regions of Brazil. Serum samples were collected from 1789 animals and tested by indirect enzyme-linked immunosorbent assay (ELISA). The overall prevalence of T. gondii was 83.40% (1492/1789). The prevalence rates of T. gondii-seropositive animals observed in the states of Pará, Tocantins and, Mato Grosso were 87.45%, 87.79% and 73.06%, respectively. The detection of high prevalence rates of T. gondii in cattle deserves special attention because they are the main source of high biological value protein for humans. This finding indicates the need for further studies on the risk that these animals may pose to public health. |

| Bovine dilated cardiomyopathy (DCM) is an autosomal recessive genetic disorder causing congestive heart failure and subsequent death. Recently, a nonsense mutation c.343C>T in the bovine optic atrophy 3 (OPA3) gene had been reported to cause the DCM in Holstein cattle in Switzerland. However, the mutation has not been confirmed in bovine DCM outside Switzerland. Nine Holstein Friesian cows that were macroscopically and histologically diagnosed with or suspected of DCM and 12 control cows kept in Japan were tested for the mutation. The mutation surrounding OPA3 DNA fragment was amplified by PCR and subjected to direct sequences. The homogeneous c.343C>T mutation was proved to occur in all the affected cows and not in the control cows. The present... |

| This study has attempted to identify determinants of cattle price per kilogram live weight using a log-linear regression model. The estimated model explains about 48% of the variation in market prices of cattle. Price per kilogram live weight of cattle increases with animal characteristics such as age, live weight and grade. Type of sellers, buyers' purposes, festivals, time of transaction and a time trend are also important variables in affecting cattle prices. Farmers tend to sell their animals at price discounts as compared to trader sellers. Cattle sellers suffer from price discounts in selling to buyers with business purposes in comparison to selling to ultimate consumers. Sellers tend to benefit from animal sales during festivals, as they tend to... |

| Three soluble antigens were compared by radial immunodiffusion (RID) and agar gel immunodiffusion (AGID) tests: a native haptene (NH) from Brucella melitensis 16M, and a polysaccharide (PS) from B. abortus 1119-3, both obtained by non-hydrolytic methods, and the (O-Chain) polysaccharide extracted also from B. abortus 1119-3 but using an hydrolytic method. Three groups of bovine sera were tested: a) Naturally infected (n = 76); b) Non-infected (n = 130) and c) S-19 vaccinated (n = 61); the sensitivity (Se), the specificity (Sp) and the ability to differentiate vaccinated (ADV) were determined in each group a, b and c respectively. The highest Se in the RID test (84.3%) was achieved by NH; while the three antigens gave 100% Sp. The O-Chain showed 100% ADV in... |

| A neosporose em bovinos é uma doença causada pelo protozoário Neospora caninum, identificado pela primeira vez em 1988, em cães com encefalomielite, o hospedeiro definitivo. Estudos sorológicos de vários países demonstraram o parasita como a maior causa de abortos em rebanhos leiteiros. A doença está amplamente disseminada nos diferentes continentes. A importância econômica da neosporose bovina é atribuida principalmente aos custos associados ao aborto, ao valor dos fetos, à inseminação artificial ou à cobertura, à diminuição da produção de leite, ao aumento do descarte e à reposição dos animais.Em bovinos, os dois mecanismos de infecção por N. caninum são as transferência do parasita da mãe para o feto (transmissão vertical ou infecção congênita) e a... |

| Abstract Tuberculosis is a serious disease of humans and animals, caused by bacteria of the Mycobacterium genus. This leads to complications in the life of the sick person, and subsequently to death. The cattle, who have been diagnosed with this bacterium, are usually sent to the slaughter, with the result that their livestock is reduced. Mycobacteriosis is also a disease, after determining which cattle are most often sent to slaughter. Such a reduction in livestock numbers has a negative effect on the economy. Of the 300 samples from the animals, 25 cultures of atypical bacteria responding to tuberculin were isolated. A series of tests - intravenous tuberculin test, ophthalmic test, palpebral test, "ZhAT" test, showed that most of the tuberculosis changes... |

| 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.

| In 1995 and 1996, prices for weaned calves were at the lowest point for the current cattle market cycle. The National Animal Health Monitoring System (NAHMS) Beef ,97 Study examined the effects of the down market on beef cow-calf herd management practices. Most producers did not alter management practices in response to the down market. Among producers who made changes, costs were cut largely in the area of herd health management. Specific management practices in which costs were cut included decreases in use of vaccinations (7.4% of operations), herd medications (7.7% of operations), individual cow medications (5.0% of operations), and veterinary services (14.1% of operations). Other ways that producers altered management practices in response to the down... |

| Cattle production is the largest single agricultural sector in the U.S. with cash receipts of $49.2 billion in 2005. Like the rest of agriculture cattle producers have adopted efficiency and quality improving technology to meet consumer demands for a safe, wholesome, and affordable food supply. This research uses meta analysis to combine over 170 research trials evaluating pharmaceutical technologies in the cow-calf, stocker, and feedlot segments of beef production. These results were used to estimate the farm level economic value of parasite control, growth promotant implants, sub-therapeutic antibiotics, ionophores, and beta agonists for the industry in 2005. The Food and Agriculture Policy Research Institute (FAPRI) model of U.S. agriculture was used to... |

| Due to a lack of national information about cull dairy cows, the USDA's National Animal Health Monitoring System (NAHMS) Dairy '96 Study investigated culling management practices. Operations included in the study represented 83.1 percent of U.S. milk cows. Most dairy cows were culled for reasons associated with their inability to profitably produce high-quality milk and calves; reasons for culling were not usually related to ill health or systemic disease. Results showed that almost all cull dairy cows in the US are intended for beef slaughter, as only about 4.4 percent were sent to other dairy operations. Nearly 77 percent of cows intended for beef slaughter were sent to markets, auctions, and sale barns, while 22 percent were sent straight to slaughter... |

| Carcass data from more than 38,000 cattle was used to compare the called and measured yield grade in two different periods: before and after the slaughter plant incorporated another grader in the line to improve grading accuracy. The study shows that the graders accuracy significantly increased. The higher accuracy affected all yield grades, but most notably resulted in more called yield grade 4 and 5 carcasses. This analysis will develop insight of what will be the effect of instrument grading that will be more accurate than previously called grades.The results are expressed as the conditional distribution of the called yield grade for a given value of the measured yield grade. The pricing grid currently used by the industry was used to analyze the effect... |

| In almost all types of vegetation there are species that can cause toxicity to livestock that consumes. The poisoning caused problems in many different animals can affect reproduction, weight gain, and even death. These problems are causing economic losses in the livestock industry it is necessary to quantify but very difficult to achieve it. In Sonora, has been diagnosed rangeland of overgrazing, which manifests itself in a deterioration that diminishes the species desirable and undesirable increases, among these plants are toxic. We have identified 184 species that are toxic and within them there are 59 species that consume livestock and cause problems. For the foregoing are raised by this study, in order to try to estimate the economic impact that cause... |

| The present study evaluated the effect of hemoplasmosis on cattle productivity. Prevalence of bovine hemoplasma was examined by polymerase chain reaction (PCR) using whole blood samples collected from 93 breeding cows and their 71 calves in Hokkaido, Japan. Monthly milk production records and other clinical data were compared between Mycoplasma wenyonii (Mw)-infected, “Candidatus Mycoplasma haemobos” (CMh)-infected, co-infected and PCR-negative groups. Blood chemical parameters were obtained from the 93 cows and 64 calves. PCR results showed that 89.2% (83/93) of cows and 14.1% (10/71) of calves were positive for bovine hemoplasma. Based on productivity data obtained from the 93 cows, Mw-infected, CMh-infected and co-infected cows had significantly lower... |
