“…The collection techniques are mainly eletroejaculation, rectal massage and artificial vagina, and the main cryoprotectants based on glycerol, with effective results in wild species such as impalas, giraffes, and buffaloes, among others. Testicular biopsy is an elective methodology for the collection of material for physiology and reproductive pathologies study in wildlife, providing enough material for histological analysis (Lopate et al 1989, Threlfall & Lopate 1993, Attia et al 2000, Crosta et al 2003, Azevedo et al 2006, Mascarenhaset al 2006, Guião--Leite et al 2006, Bitencourt al. 2007).…”

Currently the importance of using alternative strategies for biodiversity conservation is emphasized and since the establishment of germplasm bank is an alternative to the conservation of endangered species. This is a technique of great importance for the maintenance of Brazilian fauna. Since the early70'sthere was a growing concern about the need to preserve essential genetic resources for food and agriculture, mainly for conservation of genetic material from farm animals. Thus was created the Brasilia Zoo, in July 2010, the first Germplasm Bank of Wild Animals in Latin America, as an alternative strategy for the conservation of threatened or endangered species, using both gametes and somatic cells and stem cells. Then we argue to create new banks or research networks among different regions with aimed to tissue preservation.

“…Serum chemistries may reveal hypercalcemia, hypercholesterolemia, and hyperglobulinemia supportive of an ovulating hen. There may be a hypocalcemia present if the hen's calcium stores are depleted, and particularly if she is consuming a low-calcium diet such as seed [42][43][44]. The owner should be instructed on methods to stop the chronic egg laying as decreasing the light cycle, removing the male bird, and/or changing location of the cage.…”

“…Dystocia may cause metabolic disturbances by interfering with normal defecation and micturition, and cause ileus and renal disease, respectively. The severity of the patient's condition can be estimated by the degree of depression and the length of time clinical signs have been present [42][43][44].…”

“…Such enhanced genetic potential along with the sophisticated feeding management strategies make the bird susceptible to different types of reproductive disorders. Although it is well known that reproductive disease of poultry results in significant economic loss by decreased egg production and increased mortality, avian reproductive pathology is still in its infancy compared to mammalian reproductive disorders (Solomon, 2002;Crosta et al, 2003).…”

| Avian oviduct is a tubular organ and its muscular contraction responsible for recurring ovum transportation, egg formation, oviposition, sperm transport and fertility. Any defect in oviduct motility may have a great bearing on the above said functions and also results in internal laying or ectopic oviposition. Modern commercial layer are highly prolific and susceptible to internal laying however their prevalence, nature and significance is not known. Hence a study was undertaken to assess the prevalence and clinico-pathological aspects of internal laying in commercial white leghorn layer chicken in Namakkal region of India. A total of 5145 carcasses of white leghorn layers, above 20 wks age from 255 flocks were examined for various oviduct abnormalities for a period of four years (2006 to 2009). Among all the cases examined for reproductive tract abnormalities, 51 (0.99%) cases from nine flocks revealed internal laying with an overall drop in egg production, morbidity and mortality of 0.5 to 1.0%, 0.5 to 1.0% and 0.2 to 0.5 % respectively between 21 and 80 wks. of age. Necropsy examination revealed distended abdomen, few to numerous, partial as well as fully formed eggs along with yolk materials in the peritoneal cavity. On the basis of oviduct lesions, the causes of internal laying were identified as thin shelled eggs (33.33%), salpingitis (27.45%), vent trauma (17.65), heat stress (3.92%), oviduct neoplasm (1.96%) and unknown cause (15.69%). Microbial analysis of samples revealed the presence of Escherichia coli in cases associated with salpingoperitonitis. Internal laying was noticed in layers with highest occurrence in 21-30 wk. (25.49%) and 41-50 wk. (21.57%) of age and during summer season (49.02%). It was concluded that the presence of eggs in the abdominal cavity and lesions in the shell gland and vagina indicates the functional alterations of the distal parts of reproductive tract could be responsible for internal laying.
