<p>Cadmium (Cd) is a persistent environmental pollutant known to impair male reproductive function following bioaccumulation. This study evaluated the histopathological and morphometric effects of acute cadmium exposure on the testes of adult Syrian golden hamsters (<em>Mesocricetus auratus</em>). Animals (n = 5 per group, with each group assessed in triplicate) received intraperitoneal cadmium chloride at 0.5, 1.0, or 2.0 mg/kg body weight for 10 consecutive days; control animals received saline. Histological examination revealed dose-dependent seminiferous tubule degeneration, pyknotic nuclei, germ-cell exfoliation, luminal cellular debris, widening of the interstitial spaces, epithelial thinning, and reduced luminal spermatozoal density, with the most severe changes observed at 2.0 mg/kg. Morphometric analysis using ImageJ corroborated these findings: seminiferous tubule area decreased from 579,418.6 ± 35,325.6 µm² in the control group to 389,477.6 ± 53,283.5 and 294,111.8 ± 52,149.5 µm² in the low- and high-dose groups, respectively (<em>P</em> &lt; 0.05); tubule diameter decreased from 889.2 ± 62.8 to 615.2 ± 68.0 µm, and epithelial height decreased from 292.2 ± 49.6 to 140.0 ± 25.5 µm, with significant reductions only at the high dose; the spermatogonia count decreased from 381.4 ± 21.1 to 249.4 ± 31.6, 226.8 ± 22.3, and 140.2 ± 25.3 across the treated groups (<em>P</em> &lt; 0.05). These findings indicate progressive, dose-related disruption of testicular architecture and spermatogenesis and support the suitability of the Syrian golden hamster as a model for heavy-metal-induced reproductive toxicity.</p>

<p><strong>Aims:</strong> To evaluate the effects of a pelleted diet, compared with a forage-based diet supplemented with concentrate, on growth performance, carcass characteristics, and technological properties of meat in captive grasscutters.</p> <p><strong>Study Design:</strong> Completely randomised controlled feeding trial.</p> <p><strong>Place and Duration of Study:</strong> Laboratory of Animal Science and Animal Production, Félix HOUPHOUËT-BOIGNY National Polytechnic Institute, Yamoussoukro, between September 2018 and January 2019.</p> <p><strong>Methodology:</strong> Eighteen weaned male grasscutters (<em>Thryonomys swinderianus</em>; 45 ± 7 days old; 528 ± 190g) were randomly assigned to a pelleted diet (growing: 19% ADF; finishing: 17% ADF) or a forage-based diet supplemented with concentrate (n = 9 per treatment). Animals were reared individually until six months of age. Growth performance, carcass traits, and technological properties of meat were assessed after slaughter.</p> <p><strong>Results:</strong> Grasscutters fed the pelleted diet had a significantly higher final body weight (2,693g), exceeding that of the forage-fed group by 968g, and a greater average daily gain during the finishing phase (17g/day; <em>P</em> = .01). The pelleted diet significantly increased hot (2,172g), chilled (2,155g), and commercial carcass weights (2,109g) (<em>P</em> ≤ .002), as well as the weights of the forequarter (506g), loin (444g), and hindquarter (833g) (<em>P</em> &lt; .001). Dressing percentage (80.7%), net carcass yield (92.3%), commercial carcass yield (78.4%), meat proportion (92.0%; <em>P</em> = .04), and muscle-to-bone ratio (11.7; <em>P </em>= .02) were also higher, whereas cooking loss was lower (15.4%; <em>P</em> = .03).</p> <p><strong>Conclusion:</strong> A complete pelleted diet improved growth performance, carcass traits, and technological properties of meat in growing grasscutters. This feeding strategy could shorten the fattening period and improve the productivity of grasscutter farming systems.</p>
