Casein fractions of ultra high temperature milk with different somatic cell counts

ZAFALON, L. F.; CUNHA, M. L. R. S.; ALVES, T. C.; FERREIRA, E. M..

No Brasil, a homeopatia é a principal forma de controle da mastite em rebanhos orgânicos. Entretanto, desconhece-se a capacidade desse tipo de tratamento de controlar bactérias patogênicas relevantes à saúde animal e humana, como aquelas do gênero Staphylococcus. Esses micro-organismos apresentam fatores de patogenicidade, como a produção de biofilmes e questiona-se a possibilidade de essas bactérias permanecerem na glândula mamária de vacas tratadas com homeopatia, mesmo após o uso destas terapias alternativas. Assim, buscou-se investigar Staphylococcus spp. em leite de vacas com tratamento homeopático contra a mastite e a formação in vitro de biofilmes por esses patógenos. As vacas lactantes foram divididas em dois grupos antes do início do experimento,...

The objective of this work was to evaluate the effect of somatic cell counts (SCC) in casein fractions of ultra high temperature (UHT) milk. Raw milks were categorized in SCC groups of low (200,000-320,000 cells mL-1), intermediate (380,000-560,000 cells mL-1) and high cells (600,000-800,000 cells mL-1). Five replicates of UHT milks within each SCC category were analyzed for casein fractions after 8, 30, 60, 90 and 120 days of storage through high performance liquid chromatography. SCC showed effect only on beta-casein reduction. SCC in raw milk increases the proteolysis of UHT milk, as a consequence of beta-casein degradation.

Abstract: The objective of this work was to evaluate the chemical composition and fatty acid profile of milk from F1 Holstein/Zebu cows in different lactation periods, when receiving different levels of dietary supply in percentage of body weight. Sixty cows were evaluated, with five levels of dietary supply and three lactation periods. The levels of dietary supply had no effect on the production of milk corrected to 3.5% fat (12.25 kg per day). There was also no effect of dietary supply levels, in the different lactation periods, on contents of fat (3.34%), protein (3.41%), lactose (4.60%), total solids (12.0%), defatted dry extract (8.80%), and urinary nitrogen (14.5 mg dL-1), nor on somatic cell count (89.98 mL-1). As the dietary supply level was...

The relation between the moment at which a recall of Dutch custard is initiated and the direct costs of this recall was investigated. A simulation model of the custard supply chain was developed to compare scenarios with and without a quarantine of 48 h at the storage of the production plant. The model consists of three parts; first the distribution of a 24,000 L batch of custard over the supply chain over time is simulated, second the time to detect spoilage bacteria with a recontamination test procedure is simulated, third the direct recall costs of custard over the different parts of the supply chain are calculated. Direct recall costs increase from about €25,000 per batch to €36,171 from 57 to 135 h in the situation without quarantine and from €25,000...

Importance of standardizing raw milk quality for the enhancement of Croatian market competitiveness

AgEcon

Tolusic, Zoltan; Mijic, P.; Tolusic, M..

In the European Union member states (EU), it is necessary to evaluate hygienic condition of milk in order to determine milk price. Similar requirement was set by the Republic of Croatia in 2000. The Rulebook defines minimal quality criteria that fresh raw milk must have in order to be purchased. Upon completion of analysis, milk is classified into quality classes, each having a defined price. Increased value of somatic cell count (SCC) (higher than 400.000/ml) and MO (higher than 100.000/ml) directly decreases the raw milk price, while higher content of fat and protein causes its increase. Since the system of market milk price formation was established, producers have been stimulated to produce milk of higher quality: in a total of milk being purchased,...

Economic viability of feeding dairy cows on diets containing different levels of soybean oil

Lopes,Marcos Aurélio; Lage,Luciana Andrade; Lopes,Fernando César Ferraz; Ribeiro,Carlos Gustavo Santos; Gama,Marco Antônio Sundfeld da; Rodriguez,Norberto Mario.

The objective of this study was to evaluate the economic viability of feeding dairy cows with diets containing different levels of soybean oil. Cows were fed diets based on tropical forage (Pennisetum purpureum Schum) supplemented with different levels of soybean oil (0.0, 1.5, 3.0, and 4.5% of diet DM). The calculations were made considering the prices of the dietary ingredients and the daily consumption of each dietary treatment. The milk quality-based payment was estimated on the bonus paid for milk fat and protein contents according to two systems used by companies of the dairy sector. The economic benefit was calculated as the difference between the income obtained from milk sale and the cost associated with animal feeding. The MOP scenario analysis...

The majority of sheep milk produced in the world is transformed into cheese. Feeding is a major factor affecting the quality of sheep milk and, therefore, of sheep cheese. Because fat is the main compound of cheese, this review gives an update on the effects of feeding and nutrition on milk fat content and deeply discusses feeding strategies aimed at increasing the levels of healthy fatty acids (FA), such as conjugated linoleic acid and omega-3 FA, in milk and cheese in the human diet. In addition, the use of alternative feed resources such as by-products, aromatic plants, and phenolic compounds in the sheep diet and their effects on milk and cheese FA composition are also discussed. Among feeding strategies, grazing and the use of supplements rich in oils...

The effects of inactive dry yeast (Saccharomyces cerevisiae) from sugar cane were studied in 18 primiparus Saanen dairy goats (51.07±1.43) on dry matter intake and digestibility, milk production and quality. Animals were distributed in a completely randomized design during 90 days (from day 60 of milking). Diets were composed of soybean meal; soybean meal + dry yeast; or dry yeast, as protein sources, and ground corn, mineral supplement and corn silage (40%). Animals fed the dry yeast diet showed lower intake of dry matter (DM), organic matter (OM), crude protein, ether extract and neutral detergent fiber. Diets did not influence milk yield; however the milk production efficiency (kg of milk produced/kg of crude protein ingested) was better in goats fed...

ABSTRACT The distribution of conjugated linoleic acid (CLA) in dairy products commercially available in Chile is poorly understood. This study aimed to assess the content of CLA in dairy cow products from Chile and the effect of processing fresh milk into dairy products. Samples of raw milk were categorized into two groups based on the animal feeding system utilized by the dairy farm: 1) grazing based systems (Los Lagos region); and 2) housing systems using total mixed ration (TMR) diets (Los Angeles region). Simultaneously, commercial samples of condensed milk, powdered milk, butter and Gouda cheese were analyzed. Furthermore, samples of raw milk and processed products (powdered and sweetened condensed milk) were also analyzed. Dairy farms based on...
