Cryoprotective Property of Ethylene Glycol in Regard to the Quality and Mitochondrial Status of Frozen Indian Red Jungle Fowl () Semen.

Ethylene glycol (EG) has been employed as a cryoprotectant for many years in mammalian semen cryopreservation but not assessed for birds except for its recently illustrated beneficial effects on commercial chicken lines. The Indian red jungle fowl is facing trouble in its native range due to human encroachment. Therefore, the present study was designed to elucidate the cryoprotective effect of different EG concentrations (5%, 10%, 15%, and 20%) on frozen Indian red jungle fowl semen.

Effect of ascorbic acid on metabolic status, lipid peroxidation, antioxidant activity and quality of frozen Indian red jungle fowl (Gallus gallus murghi) semen.

The Indian red jungle fowl population is decreasing in its natural habitat. Its conservation through semen cryopreservation with sufficient live sperm recovery rate is requisite where ascorbic acid could play significant role to mitigate cryo-incited injuries. The objective was to elucidate the effect of ascorbic acid on freezability of Indian red jungle fowl sperm.

Sperm binding to hyaluronan is an excellent predictor of Nili-Ravi buffalo bull fertility.

This study reports the first evaluation of sperm hyaluronan binding assay (HBA) for predicting the fertility of Nili-Ravi buffalo bulls in relation to standard parameters of sperm quality. Cryopreserved semen doses of low (n = 6), medium (n = 3) and high fertility (n = 8) bulls based on their respective return rates were used. Significantly, more spermatozoa bound to hyaluronan from the most fertile bulls (57.

Effect of Synergism Between Carboxylated Poly-l-Lysine and Glycerol on Freezability of Nili-Ravi Buffalo () Semen.

Carboxylated poly-l-lysine (CPLL), an ampholytic polymer, has remarkable cryoprotective properties. It was hypothesized that CPLL will reduce/replace glycerol in extender and improve the freezability of buffalo semen. The objective was to evaluate various combinations of CPLL and glycerol in extenders for any synergism toward cryosurvivability of Nili-Ravi buffalo sperm.

A Hybrid Approach for Modeling Type 2 Diabetes Mellitus Progression.

Type 2 Diabetes Mellitus (T2DM) is a chronic, progressive metabolic disorder characterized by hyperglycemia resulting from abnormalities in insulin secretion, insulin action, or both. It is associated with an increased risk of developing vascular complication of micro as well as macro nature. Because of its inconspicuous and heterogeneous character, the management of T2DM is very complex.

Honey as an Alternative to Antibiotics for Cryopreservation of Nili-Ravi Buffalo Bull Spermatozoa.

The antimicrobial properties of honey have stimulated interest in evaluating it as an alternative to antibiotics for cryopreserved buffalo semen. , and honey were analyzed and honey was found suitable in terms of quality and purity. Buffalo semen (24 ejaculates) was studied for dose tolerability to honey (0.

Cryopreservation of Indian red jungle fowl (Gallus gallus murghi) semen with polyvinylpyrrolidone.

The Indian red jungle fowl is a sub-species of the genus Gallus native to South Asia; facing high risk of extinction in its native habitat. During cryopreservation, permeable cryoprotectants like glycerol are usually employed and we previously showed encouraging results with 20% glycerol. Because bird spermatozoa contain very little intracellular water, the possibility of replacing an internal cryoprotectant by an external one is opened.

Sperm sexing in Nili-Ravi buffalo through modified swim up: Validation using SYBR green real-time PCR.

Sperm sexing through flow-sorting technology is relatively expensive, requires considerable technical support and is actually not practicable in many developing countries. The aim of this study was to investigate the feasibility of producing enriched pools of X or Y chromosome-bearing sperm by a modified swim-up method. For this purpose semen was collected from five mature Nili-Ravi buffalo bulls for a period of six weeks.

A comparative analysis of sperm selection procedures prior to cryopreservation for Nili-Ravi buffalo bull (Bubalus bubalis) semen-: Assessment of its impact on post-thaw sperm functional quality.

Sperm selection techniques have been developed to get sperm suspensions enriched in motile and functional cells. Studies show that selection before cryopreservation improves post-thaw quality of cryopreserved sperm but information on buffalo bull sperm is scarce. The study was aimed to 1) perform a comparative analysis of sperm selection procedures; Swim-Up (SU), Sephadex™-G15 Filtration (S-G15) or Glass Wool Filtration (GWF) for total and motile cell recovery, 2) to assess the impact of sperm selection prior to cryopreservation on sperm quality (motility, morphology, cell membrane and normal apical ridge, viability and livability, chromatin integrity) and sperm functionality (Embryo Cleavage after IVF with selected sperm) in post-thawed suspensions of buffalo bull sperm.
