Whole grains in the finishing of culled ewes in pasture or feedlot: Performance, carcass characteristics and meat quality.

In order to evaluate the performance, carcass characteristics and meat quality of culled ewes finished in pasture or exclusivelywith grain, 41 culled Polwarth ewes, were assigned to six treatments: RY (ryegrass pasture), RYGO (ryegrass and whole grain oats), RYGM (ryegrass and whole grain maize), GM (whole grain maize), GO (whole grain oats), GS (whole grain sorghum). The finishing systemof the ewes influenced weight gain,wherein the GM and GS treatments increased daily weight gain. The GO treatment decreased the dressing percentage. Nonetheless, a*, h*, pH, cooking loss and tenderness were similar across dietary treatments. Using principal component analysis, the variables C18:2n6, h*, n6/n3, TBARS, total lipids, L* and b* were assigned as characteristics of meat from the feedlot animals, while the pasture finishing system produced meat with higher CLA and n-3 fatty acids but lower TBARS values indicating lipid stability.

Analysis of polyphenols in brewer’s spent grain and its comparison with corn silage and cereal brans commonly used for animal nutrition

Brewers spent grain (BSG) could be tested as an alternative source of polyphenols in animal nutrition. Proper extraction and analytical methods are critical for quantification. Thus, extraction for BSG, corn silage, and brans of rice, corn, and wheat were studied for the highest yield of polyphenols. A method for 18 phenolic monomers by HPLC-DAD was developed, validated, and applied to samples. An aqueous solution of NaOH (0.75% w/v) using integral samples for extraction resulted in the highest values for colorimetric measurements in all analyzed sources. Method by maceration showed the highest phenolic yield when applied in corn silage and BSG. However, for brans the best method was microwave assisted. Results from HPLC-DAD analysis clearly showed that native structures of phenolic compounds were simplified to its monomers allowing quantification and sample discrimination. BSG had the highest concentration of polyphenols and could be a promising and innovative source for animal feed studies.

THE RETURN OF THE SHEEP INDUSTRY PRODUCTIVE SCENARIO OF RIO GRANDE DO SUL

This review aims to conduct a historical analysis of the production chain of sheep in the Rio Grande do Sul, for this purpose we studied the market before the crisis laneira, the late 80s, and the return of productivity after the change in the focus of production. The sheep were introduced in Brazil in the sixteenth century, but only in the twentieth century the activity generated economic development in Rio Grande do Sul, in this period the main product was exploited wool. However, in the late 80s was the beginning of the crisis in the sector laneiro, mainly caused by an increase in inventories of wool from Australia, the marketing of synthetic fabrics and global crises and collapses. Currently identified is the return of the sheep production industry dedicated to meat eating as a result of factors such as the increased purchasing power of the population and adapt to new consumer habits that lead to appreciation for sheep meat. The trends for this market are promising. However, there are some barriers to growth, as the disorder of the sector and the lack of standardization of products. For the state to become major producer of sheep meat is necessary to organize the sector, from production to distribution channels.

RELAÇÃO ENTRE FAIXAS DE RENDA E O PERFIL DOS CONSUMIDORES DE CARNE BOVINA DA REGIÃO SUL DO BRASIL

The beef is present in the diet of Brazilians and their demand is linked to several factors such as price, quality, preference, flavor, and mainly socioeconomics standards of consumers. The aim of this research was to relate the income as well as characterize other factors that determine and influence the consumption of beef in the population of Santa Maria, RS, Brazil. We applied 797 semi-structured questionnaires by 16 trained interviewers. After the application of the questionnaires, the data were tabulated and analyzed. Among the respondents, 98.37% consume beef. The rib is the main cut chosen by consumers, however, consumers buy effectively topside. The highest percentage of respondents earn of 1-3 minimum wage monthly. The choice of the place that consumers purchase meat products is preferably given by their proximity of residence. Consumers would be willing to pay more for a beef certified by its tenderness. There is a tendency to increase consumption and price paid per kilogram of beef with the increase of the consumers purchasing power. Thus, it is possible to conclude that the purchasing power of the population interferes with the purchase of different cuts of beef consumed.

ECONOMIC LOSSES DUE TO CONDEMNATION OF SWINE ORGANS IN SLAUGHTERHOUSES UNDER MUNICIPAL INSPECTION SERVICE

This study aimed to measure the economic losses caused by the condemnation of swine organs in municipal slaughterhouses under the supervision of the municipal inspection system (MIS) from the city of Santa Maria-RS during 12 months in a row. The study was conducted by collecting data from slaughterhouses in Santa Maria, Rio Grande do Sul, Brazil, in MIS. The registered data took into account the number of animals slaughtered, number of condemned organs and major lesions that led to condemnation from October 2010 to September 2011. During the evaluation period, 6,193 animals were slaughtered. It was found that 5,511 organs were condemned, mostly because of aspiration of blood (n = 1,231), larval migration in liver (n = 991), and renal cyst (n = 807). The survey revealed that R

8,919.00. In order to reduce economic losses, it is necessary to do something against the critical points of condemnation, in which the main one observed in the study was the disposal of liver caused by larval migration.

INCORPORAÇÃO DE FIBRA ALIMENTAR EM PRODUTOS CÁRNEOS

Brewers spent grain (BSG) as a partial substitute for corn silage (CS) was evaluated in finishing feedlot steers on the lipid, protein, color, and microbiological stability of vacuum-packed meat for 75 days under refrigerated storage. Twenty steers were distributed in four treatments in a completely randomized design with five replicates each: 50% concentrate + 50% CS; + 35% CS + 15% BSG; + 25% CS + 25% BSG; and 15% CS + 35% BSG for 90 days. After the animals were slaughtered and the carcasses cooled, the Longissimus thoracis muscle was collected for analyzes. The lipid and protein oxidation, color parameters and microbiological stability of the beef although not affected by the diets (P > .05) oscillated throughout the storage time (P < .05). BSG can be included in the finishing diets of beef cattle by up to 35% (dry basis) and as a forage source without adverse effects on beef shelf life.

Neste trabalho se analisa a responsabilidade civil pelo dano ambiental na Espanha. Para tanto, se analisa a Diretiva 2004/35/CE do Parlamento Europeu e do Conselho em conjunto com a lei de responsabilidade civil ambiental da Espanha, destacando as diferencas entre o Direito publico e o Direito privado. Posteriormente, se expoe as causas que excluem a responsabilidade civil de acordo com a referida lei. Por fim, se apresenta breves consideracoes e a conclusao.

POST - SLAUGHTER FACTORS THAT CONTRIBUTE TO MEAT TENDERNESS

Dietary fiber can be classified according to their functionality in soluble and insoluble. Insoluble dietary fibers have porosity, low density, ability to increase fecal bulk due to the hydration there of and to be higher and transit time enhances bowel. In contrast, the soluble fraction is characterized by forming gel, acting as an emulsifier and suffers fermentation. Due to the viscosity and fermentation, soluble fiber has greater relevance to health as it acts in reducing blood cholesterol levels, blood glucose control helps with the immune system, prevent diseases, among these cancer, and contributes to the decrease of hollowing stomach. Soluble fiber can be incorporated in a larger quantity without changing the texture and tastes of food when compared with the insoluble fractions, in this sense, several studies are conducted in order to assess the addition of fiber in meat products. Meat and meat products are recognized by high lipid composition unwanted health, such combined rheological and functional characteristics of the fibers, attribute allows the replacement of fat by non-digestible carbohydrates. Another highlight advantages such as increased water retention capacity, increased emulsion stability that helps product yield , besides the development of a functional product without changing its acceptability.
