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. Multivariate analysis of morphometry effect on race performance in Thoroughbred horses
ABSTRACT The objective of this study was to determine the effects of morphometric measurements on race performance (m/sec) of Thoroughbred horses. Data of morphometric measurements (withers height, rump height, chest girth, chest width, front chest width, chest depth, neck length, shoulder length, length of withers to rump, rump length, body length, head wid

4. Biomass Deposition and Chemical Composition of Litterfall in Clonal Eucalyptus Plantations
ABSTRACT Productivity in clonal eucalyptus plantations depends on the genetic material and on the demand and cycling of nutrients, making studies that evaluate these requirements necessary. The aim of this study was to evaluate the effect of management (with and without thinning) on the deposition, chemical composition and nutrient contribution in litter at

5. Solexa Profiling Identifies Differentially Expressed MiRNAs Between Sexually Immature and Mature Equine Testis
ABSTRACT MicroRNAs (miRNAs) are a class of short non-coding RNAs identified as potent regulators of gene expression. Previous studies have suggested that miRNAs are involved in mammalian spermatogenesis. Stallion fertility is an important trait for the horse breeding industry, but stallion fertility traits are largely ignored in the industry. In this study,

6. Viability and fertility of cooled equine semen diluted with skimmed milk or glycine egg yolk-based extenders
Two semen extenders were compared for their ability to maintain viability of horse semen during 24 hours of cold preservation, and for the pregnancy rate after artificial insemination. In the experiment 1, five ejaculates from three stallions were split-diluted in either a skimmed milk-based extender (Kenney extender) or a glycine egg yolk-based extender (Fo

7. Effect of antioxidants on stallion spermatozoa under heat stress / Efeito de antioxidantes aos espermatozoides de equinos submetidos ao estresse térmico
A avaliação da eficácia reprodutiva do garanhão e do sêmen resfriado e⁄ou congelado é de fundamental importância na prática reprodutiva dos eqüinos. Predizer a fertilidade de um garanhão constitui uma decisão subjetiva. O presente estudo foi realizado com o objetivo de testar diferentes técnicas de coloração, assim como testes que avaliem

8. Viability and fertility of equine semen diluted with two seminal extenders and cooled at 5 C for 24 hours / Viabilidade e fertilidade do sêmen equino resfriado a 5 C por 24 horas com dois diluidores
Objetivou-se neste estudo avaliar a eficácia de dois diluidores um à base de licina-gema de ovo e outro à base de leite em pó resfriado a 5 C por 24 horas na preservação do sêmen de garanhões da raça Mangalarga Marchador, determinada por meio de testes in vitro e avaliação da fertilidade in vivo. No experimento 1, foram utilizados cinco ejaculados

9. Avaliação "in vitro" e "in vivo" do sêmen eqüino diluído em água de coco em pó (ACP-105) e resfriado a 5C / Evaluation in vitro and in vivo of equine semen extended in powder coconut water (PCW-105) and cooled at 5C
Modern horse reproduction, in most breeds, in based on the use of artificial insemination (AI). The wide-spread use of AI has accelerated genetic progress by making selected stallion available to breeders outside the country or region where the stallion is located. When transport of semen from the collection centre to the place where the mare is to be insemi

10. Efeito do laser diodo sobre as características de motilidade, de integridade das membranas plasmática e acrossomal e de potencial de membrana mitocondial de espermatozóides criopreservados de eqüinos / Effect of diode laser on motility, plasma and acrosomal membrane integrity, and mitochondrial membrane potential of cryopreserved stallion spermatozoa
Sperm motility depends on energy consumption. In some species sperm mitochondria play an important role in the production of energy for tail activity. Low-level laser irradiation increases this production as a modulation tool. The objective of this study was to analyze the effect of a continuous 650 nm wavelength diode laser irradiation, with dose 6 J/cm2 fo

11. Suplementação com óleo de arroz semi-refinado com alto teor de gama-orizanol na dieta de garanhões / Supplementation with rice bran oil semi-refined with high level of gamma-oryzanol in stallion´s diets
Durante 60 dias foram utilizados seis garanhões de raças variadas, com peso médio inicial de 472,67±90,48 kg, alimentados duas vezes ao dia com dietas compostas por feno de Tifton (Cynodon dactylon) e concentrado comercial, suplementadas com 300 mL de óleo vegetal (óleo de arroz ou óleo de soja), além de sal mineralizado e água ad libitum.

12. Effect of the addition of glycerol in different stages of the cooling on the freezability of stallion semen / Efeito da adição de glicerol em diferentes etapas do resfriamento sobre a congelabilidade do sêmen de garanhões
The objective of the present study was to evaluate the effect on the freezability of equine semen with the addition of glycerol in 0, 35 and 60 minutes the cooling period. Semen from two adult stallions (Mangalarga Marchador) were used, totalizing 11 colections of semen. The evaluation consisted of sperm progressive straight motility, total motility, sperm v
