SummaryThe nutritional quality of milk treated by 2 previously described processes for the removal of cationic fission products has been evaluated by the use of the baby monkey (Macaca irus).The first process involves acidification of the milk to pH 5·2–5·3 and, when the treated milk was tested on baby monkeys, it was found to be nutritionally unsatisfactory. This result confirmed those previously obtained with baby pigs, from which it was concluded that the process cannot be recommended for the treatment of milk intended for young babies.Two resin beds are used in the second process and no acidification is involved. Milk treated by this process was first tested on baby rats and pigs and then on baby monkeys. No change in the nutritional value of the milk was detected and it was concluded that this is the process which should be used if it should ever become necessary to remove fission products from milk intended for young babies.

During dry seasons, equines are traditionally fed hay. However, if not prepared under favorable climatic conditions and if not properly stored, hay does not preserve its nutritional value. The aim of this research was to evaluate the chemical composition in Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, used to feed equines over 225 days of storage. Treatments consisted of Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, assessed at six moments of storage: 0, 45, 90, 135, 180, and 225 days. The experiment followed a completely randomized split-plot design. In the comparison between varieties, differences (P0.05) over the 225 days of storage. The storage period had little impact on the nutritional quality of the assessed hays. The Stylosanthes guianensis cv. Mineirão and, mainly, Estilosantes Campo Grande hay varieties have potential to be used in equine diet.

Cooking becomes the meat more digestible, eating, and palatable. However, heat treatment can cause undesirable nutritional changes in meat, such as loss of minerals and vitamins, oxidation of lipids and changes in some segments of the protein fraction. The use of sous vide processing technology, which refers to cooking vacuum-sealed food in heat-stable plastic pouches under precisely monitored conditions, represents an interesting cooking alternative in terms of retains its natural sensory qualities of meat along with the nutritional value. In this paper, the research on the effect of sous vide cooking of meat on its nutritional quality is reviewed.

The biomass, proximal composition and fatty acid profile of Isochrysis sp., Chaetoceros muelleri and their mixture, grown under greenhouse conditions, were evaluated. The nutritional value of both species supplied as the monoalgal (Chaetoceros muelleri: Diet I, and Isochrysis sp. Diet II) and mixed diet (Diet III) for larval Litopenaeus vannamei was also assessed on the basis of the development and biochemical composition of the larvae. The highest protein levels were obtained in Diets I and II (40% and 35%, respectively). No significant differences in larval survival were found among the diets; however, larvae fed on Diet II had the lowest mean larval length.

Maize and sorghum silages are good sources of energy for lactating dairy cows that produce milk destined for fresh and matured cheeses. Silages are usually stored in horizontal silos with or without side walls on commercial farms throughout the world. The main microbiological and nutritional quality problems are related to harvesting time, ensiling technology, and management practices during filling and feed-out. Aerobic deterioration is a key point that must avoided on farms in order to improve the hygienic, chemical and sensorial quality of milk and cheeses. Aerobic deterioration causes large losses of dry matter (DM) and quality, and it can cause health problems for animals and humans through the transfer of pathogens and mycotoxins from feed and livestock to food products. The objectives of the present work were to overview management practices connected to the storage of maize and sorghum in horizontal silos on farms producing milk for make Protected Designation of Origin (PDO) hard ripened cheese, to define good management practices that should be applied as the basis for safe silage production and to reduce the extent of aerobic deterioration.
