Effect of Different Levels of Egg Yolk on Cryopreservation of Black Bengal Buck Semen in Tris Egg yolk Citrate Fructose Glycerol Extender
This study was conducted to assess the physical and morphological characteristics of fresh, pre-freeze and post-thaw black Bengal buck (Capra hircus) semen processed in Tris-egg yolk-citrate-fructose-glycerol (TEYCFG) extender containing 4 different concentrations (2.5, 5, 7.5 and 10%) of egg-yolk. Ejaculates were collected once a week for eight weeks from six mature bucks (48 ejaculates) using...
متن کاملGlutathione Addition in Tris-citric Egg Yolk Extender Improves the Quality of Cooled Buffalo (Bubalus bubalis) Bull Semen
The present study was designed to see whether adding glutathione to tris-citric egg yolk extender improves the quality of buffalo bull spermatozoa stored at 5°C for five days. Semen collected from Nili-Ravi buffalo (Bubalus bubalis) bulls (n = 5) was diluted (37C; 10 x 10 motile spermatozoa per ml) with extender having glutathione (0.0, 0.5, 1.0, 2.0 and 3.0mM). The extended semen was cooled fr...
متن کاملEffects of egg yolk-citrate and milk extenders on chromatin structure and viability of cryopreserved bull sperm.
Semen from four Holstein bulls was evaluated to compare effects of four extender treatments on postthaw semen quality. Extender fractions A and B, either heated whole milk or 20% egg yolk-citrate, were combined to yield the extender treatments 1) milk and milk, 2) milk and egg yolk-citrate, 3) egg yolk-citrate and milk, and 4) egg yolk-citrate and egg yolk-citrate. Semen was evaluated at thawin...
متن کاملEffect of various levels of catalase antioxidant in semen extenders on lipid peroxidation and semen quality after the freeze-thawing bull semen
The objective of this study was to evaluate effect of different concentrations of catalase in two extenders on motility, viability and lipid peroxidation bull spermatozoa during semen freezing process. Thirty ejaculates collected from ten Holstein bulls were pooled and evaluated at 37 °C. Pool ejaculated was split into two main experimental groups, 1 and 2. In experiment 1, specimen was dilute...
متن کاملP-137: Effect of Different Equilibration, Freezing and Thawing Rate on Cryopreserved Buffalo Spermatozoa Diluted inTris- Egg Yolk Extender
Background: Artificial insemination (AI) has been used for increasing genetic potential of animals in production while application of AI has been restricted in buffalo due to low freezing ability and fertility of frozen-thawed buffalo spermatozoa. So improvement in buffalo sperm cryopreservation may enhance the breeding programs of this valuable farm animal. Semen processing is one of the major...
