The mobility of pooled turkey sperm following various storage regimens was assessed by objectively measuring the ability of sperm to penetrate a 2% Accudenz [5-(N-2,3-dihydroxypropylacetamido)-2,4,6-tri-iodo-N,N'-bis(2,3-dihydroxypropyl)isophthalamide] solution at 41 C. When semen was diluted with Beltsville poultry semen extender and stored at 5 C with agitation at 150 rpm, sperm mobility decl...

Superoxide dismutase (SOD), total antioxidant capacity (TAC), and thiobarbituric acid reactive substances (TBARS) in seminal plasma were evaluated on the basis of receiver operating characteristics (ROC) analysis as predictors for distinguishing satisfactory from unsatisfactory boar semen samples after storage. SOD on day 0 correlated significantly with progressive motility (r=-0.686; P<0.05) a...

The sperm quality index (SQI) is predictive of fresh semen quality. Our objective was to examine if semen storage affects the SQI obtained from undiluted semen, or semen diluted with either Beltsville Poultry Semen Extender (BPSE) or Minimum Essential Medium (MEM) and held for 8 h at 4, 21, or 41 C. Dead o sperm percentage was higher and SQI was lower from undiluted versus diluted semen. Dead s...

Methods of semen collection and artificial insemination (AI) in poultry, requirement for diluents, methods of liquid and frozen storage of avian semen and evaluation of spermatozoa after storage for fertilizing ability are reviewed. Frozen storage of semen from non-domestic birds is also briefly discussed.

The assessment of spermatozoa motility is one of the most often used parameters for semen evaluation. The study was conducted at Poultry Research Station, Madhavaram Milk Colony, Chennai600 051, to  nd the effect of different semen diluents and dilution ratio on per cent spermatozoa motility of pooled guinea fowl semen at 5o C under short term storage(0, 3 and 6 Hours). Irrespective of the sto...

The objective of this retrospective field study was to determine the effects of storing, for up to 62 h, heterospermic and homospermic semen in the short-term extender Beltsville thawing solution (BTS), on reproductive performance in Norwegian swine of four different breed combinations. The study was based on fertility records after single or double inseminations with semen collected at an AI s...

BACKGROUND There is some controversy about the extent of changes in different sperm cell features in stored boar semen, especially regarding the potential role of the DNA fragmentation assay for assessment of sperm fertilizing ability. The aim of this study was to assess the effect of time of storage and the dynamic changes in sperm cell characteristics in normospermic boar semen stored in long...

The present study was designed to evaluate kinematic response of sperm cell to low-density lipoproteins (LDL) in fresh diluted, short-term (4°C) or long-term (-196°C) stored semen. Four healthy bucks of similar age and weight were selected as semen donor. The semen was collected twice a week using artificial vagina. The semen after initial evaluation was pooled and divided into three aliquots, ...

The effects of different extenders and storage periods on the motility and fertilization rate of rainbow trout (Oncorhynchus mykiss) semen were evaluated after short-term storage. Semen was collected from anesthetized males by the abdominal massage. After determination of main semen characteristics, the pooled ejaculates were diluted with 4 different extenders at a ratio of 1:3, and stored at 4...
