Zinc is an essential nutrient involved in a wide range of biological functions, particularly aspects reproduction, including fertility and sex hormone production. The aim the present study was to evaluate different amounts types Zn on ejaculate collection time training behaviour young boars. Were used fifteen males (York-Landrace), 6.8-months-old with 120 Kg body weight (BW) were randomly assigned three treatments. Boars received basal diet (BD=T1) corn-soybean without addition Zn. BD...
Objetivo. Evaluar riesgos de contaminación biológica en maíz nativo para uso forrajero (Zea mays L.) cultivado con Biol excretas cerdo a diferentes dosis. Materiales y métodos. Se establecieron seis tratamientos dosis T0:0-T1:25-T2:50-T3:75-T4:100% T5: Fórmula química 120-60-00, el estudio se realizó bajo diseño experimental parcelas distribuidas al azar, cinco repeticiones. Las variables altura planta, diámetro del tallo, número nudos hojas estudiaron durante establecimiento cultivo desde...
The main objective of this study was to determine differences in sperm recovered from the three segments epididymis, i.e., head, corpus and cauda, using routine measurements quality DNA fragmentation assessment. There a larger concentration (P < 0.05) head (3.34 × 106 sperm/mL) compared with cauda. percentage normal morphology higher cauda but had lower motility 0.05). index for obtained body epididymis 0.01) values were 12% Wright stain DAPI similar Spermatobioscopy parameters match...
The aim of this study was to evaluate the effects adding conjugated linoleic acid (CLA) boar diets on semen producion and characteristics, fatty profile spermatozoa, testicle carcass parameters. Ten lean-type terminal-line (Yorkshire x Landrace Petrain) adult boars were randomly assigned one two treatments: (1) a control diet (2) same with 1% CLA. research conducted in Mexico, animals exposed ambient temperatures betwen 13.5 26.3 °C. Boars ejaculated twice per week 12-week period examine...
The effects of light on the steps embryo manipulation have been described in several species, including humans. There are reports which exposure these cells to UV rays from sunlight affects them epigenetically, could lead meiotic arrest that would prevent normal maturation germinal vesicle (GV) metaphase II (MII) stage, compromise subsequent viability. Development blastocyst was not evaluated. objective study observe difference capacity (GV MII) prepubertal gilt oocytes under conditions...
The objective of the work was to evaluate spermatic quality in Pelon Mexicano boars from Yucatan.Three said genotype were used, which trained mount a dummy.The study variables were: macroscopic and microscopic characteristics, semen motility kinetic parameters, testicular characteristics.A total 42 seminal samples evaluated, results analyzed with descriptive statistics, cluster analysis, correlation linear regression STATGRAPHICS Centurión XV Version 15.2.06 ® program.The odor normal,...
Zinc (Zn) is essential for the development and activity of sperm, although its cytotoxic effect on sperm has been little studied. This study evaluated organic Zn; that is, Zn-methionate (Zn-Met), DNA fragmentation boar sperm. Domestic boars (York × Landrace, Sus scrofa domesticus; n = 15) were randomly allocated into 3 levels Zn dietary concentrations: 25 (Control), 150, or 200 ppm. Sperm dynamics over an 8-wk period after Zn-Met supplementation. The Sperm-Sus-Halomax® Kit (Halosperm SL,...
Although considered a species of least concern by the International Union for Conservation Nature red list, Desert Bighorn sheep (Ovis canadensis nelsoni) is listed in Appendix II CITES (Convention on Trade Endangered Species Wild Fauna and Flora) Mexico, due to population size lack protected areas. Postmortem epididymal sperm collected from hunter-harvested ram with an unofficial Safari Club score 197 2/8 estimated 5.5 years old, were used evaluate vitro production (IVP) embryos using...
