 Todas as células em contato
com o diluente
 Tubos
 Rotação
Tipos de Estocagem
• Anaeróbica
• Aeróbica –temp ambiente
(da Europa…)- INRA 96
• Sem diferença na fertilidade

e conseqüente risco
 Controle sanitário
Desvantagens
 Má congelabilidade

fertilidade
 Menor tempo de vida
do spz
 Maior custo da IA

Envasamento
 Palhetas e Macrotubos
– 50x106 espermatozóides/ml
• Pellets
– Diluição 1+2
• Congelamento
Congelamento
• Palhetas e
Macrotubos
• 20 minutos a 4 cm
do espelho de N2
Congelamento
•Velocidade de
congelamento
•+20oC a +5oC =
–5oC/min
•+5oC a -15oC =
–10oC/min
•-15oC a –150oC =
–25oC/min
Congelamento
