<p>A produção de leite no Brasil é natureza complexa, pois depende uma base constituída elevado número produtores baixa escala e grande diversidade estratégias. Nos últimos anos, essa cadeia produtiva tem sofrido consideráveis modificações estruturais, aumentando a necessidade do conhecimento caracterização da atividade. Desta forma, o objetivo proposto neste estudo foi caracterizar propriedades rurais segundo aspectos produtivos fim identificar os diferentes sistemas bovinos leiteiros...
RESUMO: Apesar do volume de leite produzido, a qualidade da matéria-prima é um dos maiores entraves ao desenvolvimento tecnológico e à consolidação indústria laticínios no Brasil. Dentre os entraves, toma destaque contagem células somáticas leite, que o indicador mais usado em programas controle prevenção mastite todo mundo. Com objetivo identificar características manejo ordenha quantificar fatores risco elevam subclínica seus principais agentes causadores, realizou-se coleta dados in loco...
Our goal was to investigate the effect of diets containing baleages harvested from alfalfa-grass or red clover-grass mixture on production performance, ruminal fermentation and microbiota taxa relative abundance, milk fatty acid profile, nutrient utilization in dairy cows. Twenty Jersey cows (18 multiparous 2 primiparous) averaging (mean ± SD) 148 45.2 days 483 65.4 kg body weight beginning study were used a randomized complete block design with repeated measures over time. The experiment...
The dairy industry is characterised by a wide diversity of production systems. In this diverse environment, some the difficulties can be minimised through grouping units study typology. objective was to characterise systems milk from West Parana State considering rates, area, power, facilities, and marketing milk. To end, 735 semi-structured interviews with farmers were performed using questionnaire for management practices feed that used on farms. obtain explanatory variables principal...
We previously observed that diets with reduced starch concentration decreased yields of milk and protein in dairy cows fed low metabolizable diets. Supplementation reduced-starch a lipid source may attenuate or eliminate production losses. Our objective was to investigate the effects partially replacing ground corn soyhulls plus palmitic acid-enriched supplement on dry matter (DM) intake, yield composition, plasma AA concentration, N energy utilization (mean = -68 g/d balance) without...
Current milk production includes a large diversity between systems, which generates difficulties in defining microbiological standard. The adapted practical and hygienic-sanitary management methods are diverse introduce great complexity into the systems. Based on this scenario, objective of study was to evaluate types dairy systems western Parana quantify Staphylococcus sp three critical points cattle systems: milking machines, milkers’ hands, cooling tanks raw milk. A total 35 samples...
This study aimed to evaluate the digestive power of waste cassava starch extraction dried (WCSEd) and corn, in addition determining appropriate level WCSEd replace corn diet cattle. Studies vitro digestibility situ degradability were performed. The used four cattle with rumen cannula, individually fed diets containing increasing levels (0, 33, 66 100%) dry matter nutrient intake digestibility, pH ammonia concentration fluid. showed differences DM, OM NDF (P &lt; 0.05) compared but did...
The objective of this study was to evaluate milk quality for somatic cell count (SCC) analysis and total bacterial (TBC) in agroecological production systems conventional systems, relating them the frequency milking practices types facilities. conducted 2013 2014, western region Paraná State, Brazil. We used a semi-structured questionnaire identify management producers 17 dairy (DS) city Diamante d'Oeste 27 DS Toledo. Milk sampling performed monthly. Data were analyzed using two statistical...
The objective of this study was to evaluate the nutritional quality twenty-nine cultivars sugarcane. design completely randomized, with treatments (cultivars) and three replicates. evaluations were performed at 540 days after planting during phenological stage maturation sugar cane. Stalk length, number nodes per plant, internodes length stalk diameter evaluated. samples crushed, pre-dried ground for achievement chemical analysis, carbohydrate fractionation in vitro digestibility dry matter...
