1. Available space in feeders for housed sheep: social behavior and performance
ABSTRACT This study was designed to assess the effects of feeding space availability on social behavior and performance of housed crossbreed sheep through the use of three different types of feeders. Thirty-six crossbreed ewes (Santa Inês × Dorper; 2-3 years old) with initial body weight of 34.99±4.28 kg were randomly assigned to a 3 × 3 (feeder type ×

2. Staphylococcus xylosus fermentation of pork fatty waste: raw material for biodiesel production
ABSTRACT The need for cleaner sources of energy has stirred research into utilising alternate fuel sources with favourable emission and sustainability such as biodiesel. However, there are technical constraints that hinder the widespread use of some of the low cost raw materials such as pork fatty wastes. Currently available technology permits the use of lip

3. Environmental impacts and nutrient recycling on pastures grazed by cattle
Grasslands are being replaced by urbanization and more profitable agricultural activities around the world. Producers may be faced with land constraints and need to consider intensification of the remaining grasslands as a means of maintaining overall production on a decreasing land resource. However, intensification of the grazing system is usually associat

4. DINÂMICA POPULACIONAL DE TRACHEMYS DORBIGNI, (TESTUDINES: EMYDIDAE) EM AMBIENTE ANTRÓPICO EM PELOTAS, RS / POPULATIONAL DYNAMIC OF TRACHEMYS DORBIGNI (TESTUDINES: EMYDIDAE) IN AN ANTHROPIC ENVIRONMENT IN SOUTHERN BRAZIL
Informations about the population dynamic of Trachemys dorbigni were collected from February 2006 to January 2007, in the Santa Barbara stream, Pelotas, Brazil. It was collected 377 individuals in the traps, 160 females, 146 males and 71 juveniles. The sex ratio was not different from 1:1. Males of T. dorbigni reached sexual maturity at 127 mm length. The sm

5. Caracterização, decomposição e biodisponibilidade de nitrogênio e fósforo de materiais orgânicos de origem animal e vegetal / Characterization, decomposition and mineralization of nitrogen and phosphorus of organic materials from animals and plants
This work presents results of a set of experiments carried out under laboratory, green house and field conditions regarding to the chemical and biochemical characterization of organic materials: raw animal manures, industrial residues, green manures and composts elaborated with coffee husk. With the objective to evaluated their decomposition, mineralization

6. Eficiência do sistema de resfriamento adiabático evaporativo em confinamento do tipo freestall para vacas em lactação. / Efficiency of the adiabatic evaporative cooling system in freestall for dairy cows.
This first work aimed to evaluate the effect of sprinkling frequency of adiabatic evaporative cooling system within feed line of a freestall in relation to temperature and humidity index (THI) and black globe temperature index (BGHI) and physiological responses in dairy cows. Data were registered during 116 days from January to May 2003. Twelve multiparous d

7. Physical-chemical, nutritional and biological evaluation of acid, biological and enzymatic silage made from trash fish and fish waste from the processing of Nile tilapia (Oreochromis niloticus). / Avaliação físico-química, nutricional e biológica das silagens ácida, biológica e enzimática elaboradas com descarte e resíduo do beneficiamento da Tilápia do Nilo (Oreochromis niloticus).
In Brazil and around the world, the fish-related industry produces a great amount of waster of high biological value. Due to the lack an adequate use, this residual material is considered a problem from the sanitary, environmental and production efficiency perspectives. With the objective of minimizing environmental problems and increasing fish production ef

8. Occurrence of Rhodococcus coprophilus and associated actinomycetes in feces, sewage, and freshwater.
Freshwater, sewage, and fecal samples from various sources were examined for Rhodococcus coprophilus, associated actinomycetes, Escherichia coli, and fecal streptococci. Rhodococcus coprophilus was isolated consistently from feces of farm animals, poultry reared in proximity to farm animals, freshwater, and wastewater polluted with animal fecal wastes. It wa

9. Genotyping male-specific RNA coliphages by hybridization with oligonucleotide probes.
F-specific (F+) RNA coliphages are prevalent in sewage and other fecal wastes of humans and animals. There are four antigenically distinct serogroups of F+ RNA coliphages, and those predominating in humans (groups II and III) differ from those predominating in animals (groups I and IV). Hence, it may be possible to distinguish between human and animal wastes

10. Effect of Dietary Monensin or Chlortetracycline on Methane Production from Cattle Waste
Wastes from feedlot cattle fed finishing diets containing either monensin, chlortetracycline, or no antibiotic were investigated as substrates for methane production. We used continuously mixed anaerobic fermentors with 3-liter working volumes at 35 and 55°C; these fermentors were fed once per day. Within a few days after waste from animals fed monensin was

11. Colonization of the Botanical Environment by Klebsiella Isolates of Pathogenic Origin †
Growth, survival, and pathogenicity of Klebsiella growing in and on environmental foci were examined. Total coliforms present in raw wastes from pulp mills were in excess of 105/ml, and 60 to 80% were Klebsiella. Fecal coliform counts ranged from 101 to 105/ml. Klebsiella isolates from industrial effluents and a variety of human and bovine mastitis origins m
