The effect of artificial insemination (AI), embryo transfer (ET) to bull dams (BD), and sexed semen (SS) to cow dams (CD) with and without controlling inbreeding were studied using stochastic simulation. Three levels of embryo transfer (no ET, ET on all BD, and ET on 20% of BD), five levels of sexed semen (no SS: control, SS-X on all CD, SS-X on 20% CD, SS-Y on all CD, and SS-Y on 20% CD), thre...
Flow cytometry is considered the only reliable method for the separation of X and Y chromosome bearing spermatozoa in equines. The MoFlo SX DP sorter is highly efficient, allowing the production of foals of the desired sex. However, to achieve acceptable pregnancy rates the currently used protocol requires working with fresh semen obtained close to, or at, the sorting facility. An alternative p...
Relevance. The main direction in the improvement of dairy cattle breeds is search for ways and methods creating highly productive herds. However, successful solution these issues impossible without use modern technologies. Among them, sexed sperm a divided into Xand Y-containing spermatozoa. When using breeding, it possible to regulate receipt desired sex (heifers). effective semen will provide...
Successful Separation of X- and Y-Spermatozoa Ongole Crossbreed Using a Nano-Albumen Gradient Column
The objective of this study was to determine the efficacy separating X- and Y-sperm using nano-albumen (NA). material used in fresh semen Ongole Crossbreed bulls with progressive motility ≥ 70%. Treatments for top bottom fractions were T0 (BSA 5% : 10%) as a control, T1 (NA 2% 4%), T2 4% 6%), T3 6% 8%). Sexed evaluated characteristics kinematics, proportions sexed validated morphometric polymer...
