1. Practicability of somatic cell count and electrical conductivity as subclinical mastitis diagnostic tests in camels (Camelus dromedarius)
ABSTRACT Critical gaps exist in our understanding of the diagnostic reliability of subclinical mastitis tests in dromedary camels. Using a retrospective longitudinal cross-sectional approach, 191 lactating camels were randomly sampled from 47 camel herds to investigate at first the practicability of somatic cell count (SCC) and electrical conductivity (EC) t

2. Bacterial identification, somatic cell count, antimicrobial profile and toxigenic Staphylococcus strains search from mastitic cow milk samples on small farms properties
RESUMO: A mastite bovina impacta negativamente a produção leiteira e pode acarretar riscos à saúde pública. O presente estudo teve como objetivo a avaliação da qualidade do leite bovino proveniente de pequenas propriedades na região de Botucatu/SP. Foi realizada a contagem de células somáticas (CCS), identificação dos patógenos envolvidos nas ma

3. Composition of milk and mammary gland health in Criollo breed mares during lactation
RESUMO O objetivo deste estudo foi avaliar os componentes do leite e a saúde das glândulas mamárias de éguas da raça Crioula. Foi utilizado um total de 12 éguas, localizadas em uma fazenda no sul do Brasil. Foram retiradas amostras de leite de cada égua quinzenalmente até 180 dias de lactação. As características analisadas foram gordura, proteína

4. The effect of feeding inorganic and organic selenium sources on the performance and content of selenium in milk of transition dairy cows
ABSTRACT. The aim of this study was to determine the effects of supplementing close-up and fresh dairy cows’ diets with sodium selenite or organic sources of selenium (Se) on the dry matter intake (DMI), milk production and composition. Based on their body condition score (BCS), previous lactation milk yield and expected calving date, 24 multiparous Holste

5. Frequency of microorganisms isolated at different stages of lactation and milk production loss associated with somatic cell count and to mastitis-causing pathogens
RESUMO O objetivo deste estudo foi avaliar a frequência de isolamento de agentes causadores de mastite subclínica em um rebanho e estimar as perdas de produção associadas com CCS>200.000 cél./mL. Três cultivos microbiológicos intervalados por sete dias foram realizados em todos os animais em lactação da propriedade avaliada, no período de junho a j

6. QUALIDADE FÍSICO-QUÍMICA E MICROBIOLÓGICA DO LEITE BOVINO EM DIFERENTES SISTEMAS DE PRODUÇÃO E ESTAÇÕES DO ANO
Resumo O objetivo deste trabalho foi avaliar a interação entre sistemas produtivos e estações do ano sobre a qualidade do leite bovino. Três propriedades foram avaliadas mensalmente, durante as estações, em quatro graus de especialização dos sistemas de produção: altamente especializado, especializado, semiespecializado e não especializado. Em te

7. Influence of milk production systems and practices on somatic cell count and total bacterial count in western Paraná
ABSTRACT The objective of this study was to evaluate milk quality for somatic cell count (SCC) analysis and total bacterial count (TBC) in agroecological production systems and conventional systems, relating them to the frequency of milking practices and types of facilities. The study was conducted in 2013 and 2014, in the western region of Paraná State, Br

8. Management factors and cow traits influencing milk somatic cell counts and teat hyperkeratosis during different seasons
The objective of the study was to analyze the effect of season, parity, stage of lactation and milking procedures on teat-end condition, cow cleanliness and milk somatic cell count (SCC) and identify risk factors associated with milk somatic cell counts greater than 100,000 cells/mL. A group of 15 Italian dairy farms were visited three times during different

9. Validation of models for predicting milk urea nitrogen concentrations, estimating dry matter intake by the NRC (2001)
The objective of this study was to validate three different models for predicting milk urea nitrogen using field conditions, attempting to evaluate the nutritional adequacy diets for dairy cows and prediction of nitrogen excreted to the environment. Observations (4,749) from 855 cows were used. Milk yield, body weight (BW), days in milk and parity were recor

10. Aplicação do controle estatístico de processo (CEP) como ferramenta para a melhoria da qualidade do leite / Application of statistical process control (SPC) as a tool for improvement of milk quality
This study aimed to employ statistical process control (SPC) as a tool to improve milk quality. The first objective of the study was to evaluate SPC as tool to identify non-natural variation of milk quality that are possible to be manipulated. In this study, data on milk production, somatic cell count (SCC), and total bacterial count (TBC) of 384 farms were

11. 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
