Objective. To determine the freezing and thawing rates necessary to maintain sperm viability during cryopreservation of Bocachico semen. Materials and methods. Four interactional treatments were implemented between two freezing (rapid and slow) and two thawing (rapid and slow) curves, in a 2x2 factorial as follows: rapid freezing-rapid thawing, rapid freezing-slow thawing, slow freezingrapid th...

background and objectives: the purpose of the present study was to investigate effects of various heat shock conditions and fast freezing and subsequent thawing on the viability and recovery of bacillus coagulans and bacillus subtilis as probiotic sporeformers, and also to compare spore plate and microscopic counts. materials and methods: after preparing the final suspensions of b. coagulans an...

This paper reviews new developments in methods of freezing (high-pressure freezing, dehydrofreezing and applications of antifreeze protein and ice nucleation protein) and thawing (high-pressure and microwave thawing, ohmic thawing and acoustic thawing) for foods. With a good understanding of the solid–liquid phase diagram of water, the effects of pressure on food freezing– thawing cycles are hi...

Origanum vulgare contains high levels of phenolic compounds such as gallic acid and polyphenols such as rosmarinic acid and quercetin. The purpose of this study was to investigate the effects of Origanum vulgare extract, as a natural antioxidant, on freezing-thawing semen quality in Holstein bulls. Three Holstein bulls (5-6 years old, mean live weight 800 kg) were used for semen collection twic...

Abifract: Ef}ccts of Freezing on Major Arteries • Thirty experiments were performed in dogs to assess the effects of freezing on carotid and femoral arteries. These vessels withstood freezing and thawing without rupture. Blood within the vessels did not clot and was lysed during thawing. Histological changes of vessel walls consisted of early degeneration followed by a reparative process. Occas...

This paper reviews the effects of freezing/thawing on technological properties of meat. Thus, the effects of freezing/thawing on drip loss have been presented. At the same time, novel thawing methods opposing conventional ones have been considered.

Cryopreservation of semen from the Caspian brown trout (Salmo trutta caspius) and effects of extender type, freezing and thawing rates on fertilization ability were studied. After assessment of semen quality, one part of semen was diluted with three parts of different extender and decanted into 0.5ml straws. Freezing was carried out at two freezing levels, 1.5cm and 2cm above surface of liquid ...

OBJECTIVE The effects of aging and freezing/thawing sequence on color, physicochemical, and enzymatic characteristics of two beef muscles (Mm. gluteus medius, GM and biceps femoris, BF) were evaluated. METHODS Beef muscles at 3 d postmortem were assigned to four different combinations of aging and freezing/thawing sequence as follows; aging at 2°C for 3 wk (A3, never-frozen control), freezing...
