The study design was quasi-experimental in nature. The investigation was carried out at the Xmatkuil Wildlife Management and Conservation Unit and the Centennial Zoo in the state of Yucatan, Mexico, during the months of October to December 2001. Seventeen collared pecaries adult were electroejaculation from two captive populations. Macro and microscopic analyzes of fresh and thawed semen were carried out, also morphometric measurements of the testes, the data of sperm measurements were compared with Student´s&nbsp; t-test, a linear regression model was adjusted between spermatic and morphometric variables of the testis. Logistic regression was performed between seminal freezability and spermatic and morphometric variables. The ejaculate volume was 0.96 ± 0.98 ml, with 62.08 ± 19.10% sperm motility, concentration of 558.61 ± 537.04 x 10<sup>6</sup> spermatozoa / ml of fresh semen and vigor of 3.7 ± 0.58 on a scale of 1 to 5. On thawing the motility sperm was 35 ± 17.18% and 2.75 ± 0.62 vigor. The measurements of the sperm cell segments did not show a significant difference between the individuals of the two populations. Testicular width and sperm concentration were fitted to the logistic regression model with freezability (1 = yes, 0 = no). It is concluded that testicular width is a factor significantly associated with sperm motility and seminal freezability.</p> Montes-Pérez Rubén, Mukul-Yerves Jose, Silva-Mena Carlos, Magaña-Monforte Juan ##submission.copyrightStatement## https://www.journaljaeri.com/index.php/JAERI/article/view/30183 Sat, 03 Apr 2021 00:00:00 +0000 Indigenous Chicken Productivity and Associated Farm-Level Attributes among Producers in the Western Parts of Kenya https://www.journaljaeri.com/index.php/JAERI/article/view/30184 <p>Indigenous chicken production is an important sub-sector in Kenya. About 90% of rural communities keep indigenous chicken in small flocks. They provide the much needed high value protein and income for the rural households. Despite its importance; the productivity of the sub-sector greatly varies depending on the management systems deployed by the producers. The management systems are thought to be influenced by demographic; socio-economic and information literacy factors. This study investigated the potential links between these factors and indigenous chicken productivity in two regions in the Western parts of Kenya. The survey study adopted a descriptive approach. Semi-structured interview schedules were used to collect data from a sample of 106 smallholder producers. Purposive and multi-stage sampling techniques were used to select the participants from among producers who had shown interest in the commercialization of indigenous chicken following awareness meetings conducted by public extension agents in the two regions. Data was analyzed by use of descriptive statistics and correlation estimates using Kendalls’ tau-b and Goodman-Kruskalls’ Gamma coefficients. Gender; education levels; flock size; information literacy and access to markets had significant association (P &lt; .05) with some indigenous chicken productivity indicators that were investigated.</p> Joseph Kipkorir Cheruiyot, Merina Adhiaya ##submission.copyrightStatement## https://www.journaljaeri.com/index.php/JAERI/article/view/30184 Tue, 20 Apr 2021 00:00:00 +0000 Efficacy of Entomopathogenic Fungus Beauveria bassiana Isolates against Callosobruchus maculatus (Coleoptera: Chrysomelidae) under Controlled Conditions https://www.journaljaeri.com/index.php/JAERI/article/view/30185 <p><em>Callosobruchus maculatus </em>Fa<em>B</em> (<em>Coleoptera: Bruchidae</em>), is a major field-to-store post-harvest pest of in the tropics and worldwide.&nbsp; They cause weight loss, decreased germination potential and reduction in commercial and aesthetic value as a result of physical contamination of grain by insects, eggs and excrement, decreased nutritional value. Entomopathogenic fungi have been employed in control of a number of storage pests and has been demonstrated to have potential in control of <em>C. maculatus </em>in cowpea during storage. Nine <em>B.</em> <em>bassiana</em> isolates were evaluated for effectiveness in controlling <em>C. maculatus </em>in cowpea grain under controlled laboratory conditions. Mortality of the bruchids was evaluated stepwise where the most effective isolate concentrations against <em>C. maculatus </em>were assessed. Initial assessment involved determination of the most effective concentration among the isolates following dilution. The isolates showed significant differences on the mortality of cowpea bruchids at the different concentrations. Isolate J35 had 98.2% mortality at 5 days after application during the first season and 88.3% during the second season, which was only lower to the formulated isolates BBC and BVT. The current study shows the pathogenic effectiveness of <em>B</em> <em>bassiana</em> on <em>C. maculatus</em>.</p> Mellon Kabole, Dora Kilalo, Maina Muiru, Danny Coyne ##submission.copyrightStatement## https://www.journaljaeri.com/index.php/JAERI/article/view/30185 Mon, 10 May 2021 00:00:00 +0000
