Prolonged post cooling but not pre-cooling equilibrium length improves the viab...
Neves, Mariana Machado; Silva, Maira Corona da; Moura, Luis Claudio de Oliveira; Melo, Maria Isabel Vaz de; Mambrini, Juliana Vaz de MeloThe objective was to evaluate: (1) the influence of the length of an equilibrium period done at room temperature on cooled semen diluted in extender containing different low density lipoproteins (LDL) concentration in replacement of whole egg yolk, (2) the effect of different concentration of LDL in replacement of egg yolk in extenders for freezing ram sperm and (3) the influence of the length of an equilibrium...

Assis-Neto, Antônio Chaves de; Carvalho, Maria Acelina Martins de; Melo, Maria Isabel Vaz de; Miglino, Maria Angélica; Oliveira, Moacir Franco deThe Agouti (Dasyprocta aguti) is a wild rodent that, in the Northeast region of Brazil, is a species that is very used by the low-income population as an alternative protein source for human feeding. Thirty-one male Agouti were used, coming from the Universidade Federal do Piauí (UFPI) - Piauí State, and from Escola Superior de Agricultura de Mossoró (ESAM) - Rio Grande do Norte State - Brazil. The animals were...
Histometric analysis of testis development in agoutis (Dasyprocta aguti) raised...
Assis-Neto, Antônio Chaves de; Melo, Maria Isabel Vaz de; Carvalho, Maria Acelina Martins de; Miglino, Maria Angélica; Oliveira, Moacir Franco deThe testicular development in 31 Agoutis, of the Dasyprocta aguti species, from the birth up to 14 months of age was studied through the histometric analysis. Mid diameter and the mean area, in each testicle, were obtained through 30 crosscuts of the funiculus and/or the seminiferous tubule, by means of a computerized system for image analysis and a Zeiss CPL 10X ocular micrometric device, coupled to an objecti...

Assis-Neto, Antonio Chaves de; Melo, Maria Isabel Vaz de; Carvalho, Maria Acelina Martins de; Miglino, Maria Angélica; Oliveira, Moacir Franco deThis study has as objective to evaluate the spermatogenesis yield of Agoutis rised in captivity, through the rates found between cellular types of the seminiferous epithelium. The results showed that the spermatogenesis yield of the Agoutis since 9 to 14 months of age did not reach the stabilization point. The coefficient of efficiency of the spermatogonium mitoses, did not increase with the age. The meiotic yi...

Assis-Neto, Antônio Chaves de; Melo, Maria Isabel Vaz de; Carvalho, Maria Acelina Martins de; Miglino, Maria Angélica; Oliveira, Moacir Franco deA determinação do estabelecimento da puberdade é bastante estudada em animais domésticos e roedores, no entanto, são escassas as pesquisas com a finalidade de estabelecer parâmetros para a biologia reprodutiva em cutias. Foram utilizadas 31 cutias machos da espécie Dasyprocta agouti, oriundas da Universidade Federal do Piauí, Estado do Piauí, e da Escola Superior de Agricultura de Mossoró, Estado do Rio Grande ...

Assis-Neto, Antônio Chaves de; Carvalho, Maria Acelina Martins de; Melo, Maria Isabel Vaz de; Miglino, Maria Angélica; Oliveira, Moacir Franco deBiometric data of the testicular and corporal weight development of 31 Agoutis (Dasyprocta aguti), from the birth up to 14 months of age, were analyzed. The correlations between corporal weight, age and testicular parameters were highly significant. Testicular weight, testicular volume, as well other testicular biometric parameters (length, diameter and perimeter), evolved slow and gradually until eight months ...
