Feed supplementation withα-linolenic acid(ALA)and linoleic acid(LA)increases their content in muscle,ALA increases n-3 polyunsaturated fatty acids and decrease n-6/n-3 ratio in muscle,and LA increases rumenic acid.However,high LA supplementation may have negative effects on lambs’lipid oxidative stability of meat.When the sources of ALA and LA are fed as fresh forage,the negative effects are counterbalanced by the presence of other bioactive compounds,as vitamin E(mainlyα-tocopherol)and polyphenols,which delay the lipid oxidation in meat.There is a wide consensus on the capability of vitamin E delaying lipid oxidation on lamb meat,and its feed content should be adjusted to the length of supplementation.A high dietary inclusion of proanthocyanidins,phenolic compounds and terpenes reduce the lipid oxidation in muscle and may improve the shelf life of meat,probably as a result of a combined effect with dietary vitamin E.However,the recommended dietary inclusion levels depend on the polyphenol type and concentration and antioxidant capacity of the feedstuffs,which cannot be compared easily because no routine analytical grading methods are yet available.Unless phenolic compounds content in dietary ingredients/supplements for lambs are reported,no specific association with animal physiology responses may be established.

Heat treatments have been investigated for use in many aspects of postharvest storage.They have been developed for insect control,prevention of fungal development and prevention of postharvest storage disorders including chilling injury.The treatment times and temperature range vary widely,from days at 356C to 396C in hot air,to up to 636C for less than a minute in hot water.Much of the research has been performed to develop solutions to a particular problem,and less investigation has been conducted on the responses of the commodity to the treatment.However,since the turn of the century,a number of groups have been active in examining the molecular responses and changes that occur in commodities during and after the heat treatment.This review examines the changes at the level of transcriptome,proteome and metabolome that occur in response to the different heat treatments.

The industrial obtainment and manufacturing of food cause high levels of pollution because of the generation of waste byproducts. Over the past few years, there has been a significantly increased interest in preserving, restoring and establishing an ecological balance during food production. Many investigators propose biotechnological solutions to the treatment of industrial wastes, especially waste from the dairy industry. The aim of this review is to present biotechnological approaches to the treatment and utilization of wastes from the dairy industry, specifically for milk whey and also discussed biotechnological methods to reduce environmental pollution and obtain chemical compounds with potential applications in the industry.

Effect of Changes in Body Weight,Body Condition and Back Fat During Last Month of Pregnancy on the Reproductive Efficiency of Bos indicus Cows in the Tropics of Costa Rica

Open Journal of Veterinary Medicine 2013年第1期3卷 22-28页

作者： Jaime Galindo Carlos S.Galina Sandra Estrada Juan Jose Romero Marco Alarcon Martín Maquivar Escuela de Agronomía Instituto Tecnologico de Costa RicaAlajuelaCosta Rica departamento de Reproduccion Facultad de Medicina Veterinaria y ZootecniaUniversidad Nacional Autonoma de MexicoMexico DFMexico Programa de Investigacion en Medicina Poblacional Escuela de Medicina VeterinariaUniversidad Nacional HerediaCampus Benjamín NunezLagunillaCosta Rica department of Animal Sciences The Ohio State UniversityColumbusUSA

With the aim of evaluating how changes in the metabolic status in the last month of pregnancy affects reproductive efficiency, forty six Bos indicus multiparous cows (5.5 ± 2.4 parturitions), were used. Measurements of body weight (BW), body condition score (BCS) and dorsal back fat (BF) were taken in the last month of pregnancy, postpartum period previous to synchronization (average 50 d) and at breeding by natural mating following synchronization with a progestin (average 70 d). Average postpartum days to resumption to ovarian activity were 79.96 ± 16.5 d, and average postpartum days to conception was 88.5 ± 14 d. Days postpartum to resumption of the ovarian activity was positively correlated (0.51, P 0.01) with days postpartum to conception, also, days postpartum to conception was positively correlated with prepartum back fat (14 d before parturition) (0.44, P 0.05). It was observed that BF at calving which is an objective measurement had a low correlation with other productive variables such as BCS and BW (always less than 0.39). Body fat might be a more reliable indicator of the current metabolic status of the animal particularly in the last month of pregnancy when the indicators of BCS are somehow more difficult to interpret and subjective.

Different food operations have been intensified through assisting them by instant controlled pressure drop DIC treatment. Such processes should be defined in order to preserve the main nutritional and sensorial contents of the raw material. The present paper is dedicated to study the evolution of the main bioactive compounds (total phenolics and flavonoids) and functional properties such as the antioxidant activity of processed samples in the case of Green “Poblano” Pepper (Capsicum annuum L.). Results issued from DIC-assisted hot air drying, and DIC-assisted freezing, allowed to identifying the impact of DIC studied operating parameters, which were the saturated steam pressure and the processing time, and the best DIC treatment correlated with the considered operation.

Traditional mining activities are usually correlated with high levels of soil pollution, which is a major environmental concern. Extensive mining activities have taken place in the San Joaquin region in the State of Querétaro, México resulting in high levels of mercury soil pollution (up to 1532 ± 300 mg/kg). We isolated mercury-resistant fungal strains from the San Joaquin region soils and identified them through morphologic characteristics and ITS rDNA region sequence analysis. We determined that fungi isolated belong to the genus Trichoderma. All the isolates selected showed the ability to catalyze the volatilization of Hg. For air sampling, an active sampling device was constructed and using acid KMnO4 as an absorbent, the concentration of mercury in solution was determined through the cold vapor atomic absorption method. The results show mercury volatilization from the fungal species assay, with a maximum of 213.04 ± 32.6 μg/m3 while mycelium accumulation ranged from less than 17.5 ± 2.9 to 20.0 ± 3.4 μg/g. The fungal isolates were also evaluated for their ability to reduce mercury uptake in Arabidopsis thaliana. These observations suggest the utility of Trichoderma for the mobilization of mercury in those contaminated soils.

Foodborne Illnesses (FI) are considered an important problem in public health for their high levels of morbidity and, in some cases, of mortality in Mexico and around the world. Different agents that cause Foodborne Illnesses, in which biological agents such as the genus Salmonella spp., are included, have been often associated with outbreaks. A continued effort has been observed in the food industry, in collaboration with sanitary authorities on a global scale, through the creation and continued improvement of different procedures to prevent the contamination by Salmonella, in which the elaboration of laboratory methodologies for the detection and isolation of this pathogen in foods and, in such manner, prevents the outbreak of illnesses. However, along with the aforementioned, it has been reported that a few years ago, the appearance of an ever-increasing number of strains of Salmonella spp., in foods with multi-drug resistance to antibiotics which are used in the treatment of its illness, results in a major emphasis on the health issue related to Foodborne Illnesses and, in particular, to those generated by factors of medical dependence such as the increase in recuperation time, costs, and reduction in the number of alternative pharmaceutical treatments. This work presents a general overview of FI, in which illnesses generated by bacteria of the genus Salmonella spp., their detection in a microbiological laboratory, as well as the phenomenon of resistance to antibiotics by these bacteria, and the current and difficult issue reported through different investigations all around the world, of the rise in this phenomenon and its importance in public health, are discussed.
