13. Estudo da etiologia das principais bactérias isoladas de mastite bovina em rebanhos leiteiros de propriedades rurais de Goiás / Etiology study of the main bacteria isolated from bovine mastitis in dairy cattle farms in the state of Goias
The bovine mastitis consists of an inflammation of the mammary gland, with acute to chronic evolution, which occurs when an infectious agent attacks the mammary gland. It is characterized by physical, chemical and sensory alterations of the milk, caused by microorganisms that invade the mammary gland and cause pathological changes in the glandular tissue. Ma

14. Room for manoeuvre in time of the workforce in dairy production systems
The objective of this study was to characterize and to analyze the room for manoeuvre in time in dairy production systems (DPS). Two interviews were conducted in twenty DPS in the Northern region of Paraná, Brazil, with the following objectives: to know the management and practices involving the herd, the land area and the commercialization; and to qualify

15. Fatores associados à Infecção pelo vírus da diarreia viral bovina e pelo Herpesvírus Bovino tipo 1 em rebanhos leiteiros da Mesorregião Centro-Oriental do Rio Grande do Sul
The dairy cattle is important to supply the Brazilian market, with the state of Rio Grande do Sul as the second largest producer. Viral diseases cause several damages in the bovine production. In order to maintain and improve the level of production, it becomes important to establish health programs that allow the control of diseases that can result in large

16. Parâmetros genéticos para características lineares de tipo e produtivas em vacas da raça holandesa no Brasil / Genetic parameters for linear type and yield traits in holstein cows in brazil
The objective of this study was to estimate genetic and phenotypic parameters for 21 linear type traits over the final score and milk yield traits (MY), fat (FY) and protein (PP) in herds of Holstein dairy cattle in Brazil. The 18,500 records used in this study were collected by staff of the Brazilian Association of Cattle Breeders of Holstein between 1994 a

19. Genetic diversity between herds of Alpine and Saanen dairy goats and the naturalized Brazilian Moxotó breed.
Brazilian naturalized goat breeds are adapted to the semiarid conditions prevalent in the Northeast region of the country (which has the largest Brazilian goat heard) and represent an as yet uninvestigated source of genetic diversity. Currently, imported goat breeds are crossed with Brazilian naturalized goat breeds, endangering the genetic potential of the

20. Comportamento social de cabras em lactação após reagrupamento =Social behaviour in lactating dairy goats after regrouping / Social behaviour in lactating dairy goats after regrouping
Background: Like other farm animals, domestic goats may react adversely to unfamiliar individuals, and aggression can be minimized by avoiding the introduction of new individuals into established groups. In modern dairy herds, regrouping according to age, nutrient requirements, lactation period and milk yield level is a common management practice to enhance

21. Composição do leite e diagnóstico de mastite em caprinos) = Milk composition and mastitis diagnosis in goats / Milk composition and mastitis diagnosis in goats
Background: Milk is one of the most used foodstuffs by humans in their diet. The quality of goat milk is already regulated by Law, which takes into consideration its physical-chemical and microbiological composition parameters. Several factors contribute for the alteration of the physical-chemical and microbiological parameters of caprine milk. These include

22. Anticorpos anti-Neospora caninum em bovinos de leite do sudoeste do estado do Paraná
Since November 2007 until May 2009, 1,778 serum samples of cattle from dairy herds of the Southwest of Paraná State, Brazil, were used for search of anti-Neospora caninum antibodies. The frequency of seropositive animals, assessed by IFAT, was 24.2% (431/1,178), showing a relatively high occurrence in the studied population. These results show that Neospora

23. Molecular characterization of G and P-types bovine rotavirus strains from Goiás, Brazil: high frequency of mixed P-type infections
In this study, 331 samples from calves less than one month old from a dairy herd in the district of Piracanjuba, state of Goiás, Brazil were tested for rotavirus. Thirty-three samples (9.9%) tested positive for rotavirus. Out of those, 31 were submitted to G and P characterization by reverse transcription followed by semi-nested polymerase chain reaction. T

24. Aspectos clínico-patológicos da paratuberculose em rebanho bovino leiteiro no município de Rio Claro, RJ. / Clinic-pathological aspects of paratuberculosis in dairy cattle in Rio Claro county, Rio de Janeiro State.
The epidemic and clinic-pathological aspects of paratuberculois in a dairy cattle herd in the Rio Claro county, southern Rio de Janeiro region, are described. In the years 2006-2009, eight adult cows presented chronic-intermittent diarrhea, chronic weight loss and normal appetite. At necropsy, the subserosal lymphatics were proeminent and dilated, mesenteric
