Abstract BACKGROUND Aflatoxin M1 (AFM1) is a mycotoxin found in milk as result of the ingestion aflatoxin B1 (AFB1) by dairy cattle. Because its carcinogenic properties, control occurrence products great importance. We evaluated and seasonality AFM1 from farms with subtropical temperate climates, where significant production occurs. Forty samples raw were collected bulk tansk during summer (five climate 14 climate) winter (six 15 months 2017 conducted an analysis using enzyme‐linked...
ABSTRACT The effects of weather/season (winter and summer), milk production (high low), milking time (night day) on melatonin levels were evaluated. in the from 30 individual cows, bulk tank (BTM) 16 farms, ultra-high temperature (UHT) processed 12 brands over two seasons also assessed. average concentration was 6.98 pg/mL cows' milk, 4.71 BTM, 5.62 UHT milk. In night averaged 14.87 pg/mL, whereas it total daily winter, was, average, 74.7% higher than summer (13.89 vs. 7.95 pg/mL). low group...
<p class="Pa7">The aims of present study were to evaluate the effects milk somatic cell count (SCC) and heat stress on yield composition cows in a herd for commercial production temperate region during period 2008-2012. Data from monthly test-day records 161±9 Holstein, totaling 9,650 milkings, provided by Association Holstein Cattle Breeders Parana State, analyzed descriptive analysis, correlation, analysis variance, regression analysis. The average daily was 31.78 kg/cow, which...
Este estudo teve o objetivo de quantificar os efeitos do grupo genético, estresse térmico e a contagem células somáticas (ECS) sobre produção leite vacas das raças Holandesa, Jersey genótipos da raça Girolando, em clima subtropical. Foram utilizados 14181 registros controle leiteiro mensal durante 7 anos. As foram mantidas pastagens, com suplementação alimentar acesso à sombra. Dados estação meteorológica para determinação Índice Temperatura Umidade (THI). Ano, ordem lactação, período THI...
This study aimed to determine the frequency of Pseudomonas fluorescens, P. putida, and aeruginosa in refrigerated raw milk; their proteolytic potential; your association with aprX gene. Of 173 isolates confirmed as belonging spp., 37% were 25.4% none belongs aeruginosa. The gene was distributed proportionally between putida (68%) fluorescens (75%), but it not associated low or high potential both species. (16) (14) no identified also had potential. Considering synthesis proteases other than...
The objective of this experiment was to evaluate the effects microbial inoculants on reduced concentration gases and effluent, dry matter recovery, pH, volatile fatty acids, chemical composition orange pulp silage, using a completely randomized design, with four treatments replicates per treatment. were: silage (CONT), citrus + Lactobacillus plantarum (LAC), buchneri (BUCH), (LACBUCH). Inoculants were applied at rate 25 liters solution ton containing 1x103 CFU respectively gram silage. There...
This study reports the effect of psychrotrophs in raw milk on quality Mozzarella cheese. Physical, chemical, sensorial and textural characteristics were evaluated, indices lipolysis proteolysis assessed. The highest population (7 log cfu/mL vs. 3 cfu/mL) was associated with a decrease yield primary index, higher acidity free fatty acid index concentration. Short‐ medium‐chain acids increased all cheeses during storage, being those produced containing high psychrotrophics. No sensory...
Milk in Brazil is produced mainly by Holstein, Girolando and crossbred cattle. Animal breed number of lactations are factor that can affect productivity features the milk. The purpose this research was to evaluate influence lactation on milk productivity, physicochemical composition, Somatic Cell Count (SCC) from These data were collected a farm, north Parana state, 2006 2011. relations among parameters evaluated correlation test effects (1-6) variance analysis Tukey’s test. Holstein showed...

Thresholds for Somatic Cell Counts (SCC) and Total Bacterial (TBC) in refrigerated raw milk have been stricter Brazil since July 2014.We evaluated whether the composition of 11,051 samples delivered to processing plants Paraná state, Brazil, by cooperative dairy farms, complies with government requirements established changes.Milk quality was from June August 2014, farms three states.Data were obtained infrared spectroscopy flow cytometry.SCC highest (p<0.05),when number mean values observed...
O presente trabalho teve como objetivo determinar os tipos de hemoglobinas em ovinos Hampshire Down e verificar se este locus encontra-se equilíbrio Hardy-Weinberg. Foram coletadas 46 amostras sangue Down, considerados clinicamente sadios. Estas foram utilizadas para a separação das por eletroforese. A eletroforese revelou uma banda lenta caracterizada hemoglobina B (HbBB), rápida (HbAA) duas bandas no heterozigoto (HbAB). variante HbAB foi mais freqüentemente encontrada, seguida pela...
Melatonin, a hormone secreted in cow milk, has beneficial effects on human health. This study aimed to evaluate the of dietary vitamin supplementation and nocturnal milking concentration melatonin milk. Twenty-one confined cows final period lactation were used for supplemented vitamins were: rumen-protected B vitamins, A, D3, E, niacin (B3) not protected from rumen degradation. The experimental had duration 10 days. Milk samples collected during first two days, without (WITHOUT), eight days...
