1. Can we use LDL instead of egg yolk in BotuCrio® extender to cryopreserve sperm from the Mangalarga Marchador stallion?
Abstract The objective of this study was to compare the BotuCrio® extender with the Merk - egg yolk and the INRA 82 modified by the inclusion of acetamide, methyl cellulose and trehalose in substitution of glycerol for freezing equine semen. The semen was diluted after centrifugation to obtain 100 x 106 of sperm/ml in: BotuCrio® (control); Merk - egg yolk

2. Influência de diferentes sistemas e curvas de congelamento na congelabilidade e fertilidade do sêmen equino
RESUMO Avaliou-se o efeito de curvas de congelação nos parâmetros espermáticos e na fertilidade, usando sêmen de alta e baixa congelabilidade. Experimento 1 - utilizou-se sêmen de quatro garanhões resistentes à congelação: grupo 1, palhetas refrigeradas até 5°C e congeladas com curva de -8°C/min; grupos 2 e 3, palhetas refrigeradas até 5°C (0,

3. Study on the pozzolanic activity of sugar cane straw ash produced using different pretreatments
This work systematically describes a laboratory study on different pretreatments of sugar cane straw to produce pozzolanic ash. Two procedures were used to accelerate the hydrolysis of celluloses and hemicelluloses and remove metallic impurities present in significant levels in sugar cane straw: hot water washing and acid leaching. Proximate analysis by ther

4. Additives on in vitro ruminal fermentation characteristics of rice straw
ABSTRACT The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO2 production, and volatile fatty acid concentration of rice st

5. Nutritional value of baled rice straw for ruminant feed
ABSTRACT The objectives of this study were to evaluate the effects of cultivation and hay making factors on chemical composition, protein fractionation, and digestibility in rice straw, as well as to identify the chemical fractions that contribute to the variation in its nutritional value for ruminants. Statistical procedures were performed in a model that i

6. Efeitos do trimetilaminoetano (TES) e ringer lactato em sêmen de macacos-aranha mantidos em cativeiro ( Ateles paniscus e A. marginatus)
The performances of the diluents TES and CEBRAN II were compared as cryopreservatives of semen from non human primates of the genus Ateles. The experiment was carried out using one Ateles marginatus and two Ateles paniscus specimens, males and adults, maintained in the same captivity conditions at the National Center of Primates (CENP-SVS/MS). The animals we

7. Semen cryopreservation protocols of Mangalarga Marchador stallions
The effect of the utilization of three semen protocols (Inra 82®, Merck Gema and Botu-crio®) and two filling techniques (0.25 and 0.50 mL straws) in Mangalarga Marchador stallions were studied in this experiment. Sperm parameters were assessed during processing and post-freezing. No interactions between the protocols and type of filling were observed, so t

8. Survival of Diaporthe phaseolorum var. caulivora (causal agent of soybean stem canker) artificially inoculated in different crop residues
Stem canker caused by Diaporthe phaseolorum var. caulivora is an important disease of soybean in Argentina. The objective of this study was to determine its survival ability in artificially infested straw under laboratory and field conditions. In laboratory, stem pieces of soybean, maize, sorghum, sunflower, potato and wheat were autoclaved, placed in petri

9. Assessment of the interaction between straw size and thawing rate and its impact on in vitro quality of post-thaw goat semen
The objective of this study was to analyze interactions between different straw sizes and thawing rates on the post-thaw goat semen parameters. Twenty-one ejaculates (seven per animal) were collected from three stud bucks by using an artificial vagina. After evaluation, the semen was extended in Tris-egg yolk-glycerol and packed in 0.25 and 0.50 mL straws, f

10. Alkali pretreated of wheat straw and its enzymatic hydrolysis
The efficiency of enzymatic hydrolysis of cellulose can be improved by various pretreatments of the substrate. In order to increase the efficiency of enzymatic saccharification of the wheat straw, we determined the effect of different pretreatments on the physical structure, chemical components and enzymatic saccharification of wheat straw. Our results showe

11. Microbiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste an

12. Transporte-maturação de oócitos bovinos em palhetas / Transport-maturation of bovine oocytes in straws
A demanda pela aspiração folicular associada à produção in vitro de embriões, no Brasil, aumentou com o objetivo de acelerar o ganho genético do rebanho bovino. A técnica, no entanto, apresenta limitações, especialmente relacionadas ao tempo e às condições de transporte dos oócitos até o laboratório. Para avaliar o uso de palhetas de 0,25mL n
