| The concentration and size distribution of airborne particles were measured inside and outside typical animal houses such as broilers, broiler breeders (both floor housing with litter); layers (floor housing system and aviary housing system); turkeys (floor housing with litter), pigs: fattening pigs (traditional houses, low emission houses with dry feed, and low emission houses with wet feed), piglets, sows (individual and group housing); cattle (cubicle house), and mink (cages). Using an aerosol spectrometer, particles were counted and classified into 30 size classes (total range: 0.25 – 32 µm). Particles were measured on for two days, one in spring and the other in summer, in two of each species/housing combination during 30 min inside and outside the... |

| This work documents the zootherapeutic practices in Ethnoveterinary medicine (EVM) of Pedra Lavrada (6°45'S, 36°28'W), Northeastern Brazil. We interviewed 23 people (22 men and 1 woman), who provided information on animal species used as remedies, body parts used to prepare the remedies, and illnesses for which the remedies were prescribed. We calculated the use-value to determine the most important species. Interviewees cited 11 animal taxa. The main species mentioned were ram - Ovis aries (UV=0.89), crab-eating fox - Cerdocyon thous (UV=0.79), common green iguana - Iguana iguana (UV=0.79), and South American rattlesnake - Caudisona durissa (Linnaeus, 1758) (UV=0.74). The most frequently cited treatments concerned to inflammatory and dermatological... |

| The invasin gimB (genetic island associated with human newborn meningitis) is usually found in ExPEC (Extraintestinal Pathogenic Escherichia coli) such as UPEC (uropathogenic E. coli), NMEC (neonatal meningitis E. coli) and APEC (avian pathogenic E. coli). In NMEC, gimB is associated with the invasion process of the host cells. Due to the importance of E. coli as a zoonotic agent and the scarce information about the frequency of gimB-carrying strains in different animal species, the aim of this study was to investigate the presence of gimB in isolates from bovine, swine, canine and feline clinical samples. PCR was conducted on 196 isolates and the identity of the amplicons was confirmed by sequencing. Of the samples tested, only E. coli SB278/94 from a... |

| In recent years, there has been a growing appreciation on the relevance of gastrointestinal microflora in both ruminants and non-ruminants owing to revelation of their role in several physiological functions including digestion, nutrient utilization, pathogen exclusion, gastrointestinal development, immunity system, gut gene expression and quality of animal products. The ban imposed on the use of antibiotics and hormones in feed has compelled animal researchers in finding an alternative which could overcome the issues of conventional feed additives. Though the concept of prebiotic was evolved keeping in mind the gastrointestinal flora of human beings, presently animal researchers are exploring the efficiency of prebiotic (inulin) for modulating the gut... |

| Abstract Cheese production is one of the most common forms of valorization of dairy production, adding value and preserving milk. Various types of cheese produced from raw and pasteurized milk are known worldwide. In the present work, we are interested in studying the effect of the type of milk (raw and pasteurized) of two species (cow and goat) on the yield and physicochemical characteristics of the fresh cheese. In the northeastern Algeria, on 5 cow farms and 3 goat farms; 5 raw and 5 pasteurized milk cheese manufacturing trials were conducted. The analysis of the results of the 80 samples of milk and cheese of both cow and goat species showed that the latter contained significantly more fat and protein than cow's milk and that pasteurized milk contained... |

| The purpose of this survey was to evaluate the socioeconomic and technical assistance profiles of dairy farmers from six districts in the south of Minas Gerais state, Brazil, and to identify the possible risk factors associated with total milk bacteria count (TBC) above 43,000 CFU mL-1 and bulk milk somatic cell count (BMSCC) above 595,000 cells mL-1. Most of the producers were between 41 and 60 years of age (48.9%), 74.2% did not reach high school, and 72.3% of the respondents were satisfied with their profession, although 63% would not recommend dairy farming to their children. Only 34.7% used periodic technical assistance, but 59.1% consulted it in cases of doubt. The risk factors found in the final multivariable regression models were: TBC (Did not... |

| En el período 2003-2007 en Nicaragua, se hizo un esfuerzo para lograr la producción de carne orgánica y mejorar la situación económica y social de los productores nicaragüenses, aprovechando los buenos precios de la carne orgánica en el mercado internacional. Los pocos productores que lograron producir este tipo de carne, encontraron cerrados los canales de comercialización. El esfuerzo en el área productiva, el sacrificio de los productores, se perdió. El objetivo de este trabajo es describir el proyecto, explicar las causas de los resultados y comparar dos modelos: el de la ganadería orgánica en sus diferentes etapas y el de la ganadería convencional en Nicaragua. La comparación se efectúa en condiciones de trópico húmedo y alrededor de dos variables... |

| La actividad pecuaria es de gran importancia socioeconómica para el país; la ganadería, en específico la producción de carne, es la actividad más diseminada en el sector rural. Se estima que la superficie aprovechada por la ganadería es superior a 110 millones de hectáreas, aproximadamente 60% del terrritorio nacional (SAGARPA, 2000). En el presente trabajo se estiman los efectos que se tiene sobre las cantidades ofrecidas de carne de res a nivel de granja ante un incremento en el precio del maíz, sorgo y pan. Los incrementos utilizados sobre los precios de los granos fueron del 5%, 10% y 15%, estos son ingredientes básicos en la dieta de bovinos. De igual manera, se realizo un cuestionario verbal con engordadores de Coatlinchan Texcoco edo. de México... |

| La presente investigación tiene como objetivo principal, primero: caracterizar la vegetación naturales y los principales sistemas de producción de la Cuenca Cárdenas-Comalcalco tomando en cuenta su altura, estructura y composición florística. Los resultados muestran que el 27 % de la Cuenca es vegetación natural, siendo el matorral espinoso e inerme inundable el más diverso con 169 especies registradas, seguido de las comunidades de hidrófitas con 165 espescies y el acahual con 119 espescies. En conjunto con el palmar inundable, la selva baja inundable y le manglar ocupan el 60 % de la vegetación natural, lo cual demuestra que la mayor parte de la vegetación es tolerante a la inundación, mientras que los sistemas de producción que representan el 58 %... |

| In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock use, around 85% of the nitrogen (N) returning to the soil is through animal feces and urine. However, there is a lack of information concerning the rate of nutrient return into the soil from animal feces in Southern Patagonia. In this study, we evaluated the rate of sheep faeces decomposition and nutrient (N, P, Ca and K) release in three different ecological areas of Southern Pat agonia, representing a West to East environmental gradient. Samples of fresh sheep dung were collected in the field, processed in the laboratory and located in... |
