Abstract

The study aimed to assess the digestibility, growth performance, and selected biochemical and hematological parameters of Bandjock Local pigs (BLP) and Duroc X Large White pigs (DLW). We hypothesize that the use of local ingredients in diet formulation associated to improved rearing conditions, enhance the growth performance, digestibility, biochemical and hematological parameters of BLP. The trial involved dividing twenty-four eight-week-old weaner pigs into two groups. Each group was randomly assigned to separate pig units. Animal management and feeding were consistent between both groups. The trial lasted for 120 days during which the growth performance, the digestibility of ingested nutrients, and biochemical and hematological parameters were evaluated. The results indicate that DLW pigs registered a weight gain (46.56±5.19 kg) significantly higher than BLP pigs (34.02), with a statistically similar feed conversion ratio. Except for albumin which was significantly higher in DLW and urea in BLP, there were no significant differences (p > 0.05) in total protein, cholesterol, globulin, triglycerides, creatinine, AST, and ALT as well as hematological parameters between the breeds. However, the exotic DLW had a relatively high mean blood platelets and white blood cell concentration. Although the fecal nitrogen was higher in BLP and the urinary nitrogen was lower in the DLW, there were significant differences (p < 0.05) for urine, fecal, and total excreted nitrogen in both breeds. The lowest scores in nutrient digestibility were recorded with BLP compared to DWL, except for crude fibers. The results of this study demonstrated that using diet formulated with local ingredients and improved rearing conditions, Cameroonian local indigenous pigs have a better productivity compared to exotic breeds. It suggests that efforts should be made by authorities to promote and valorize the rearing of indigenous pigs in complement to exotic pig breeds in view of strengthening the Cameroonian pig industry.

评估班卓克本地猪(BLP)和杜洛克 X 大白猪(DLW)的消化率、生长性能、血液学和血清生化指标
本研究旨在评估班卓克本地猪(BLP)和杜洛克 X 大白猪(DLW)的消化率、生长性能、生化指标和血液指标。我们假设,在日粮配方中使用当地食材并改善饲养条件,可提高本地猪的生长性能、消化率、生化指标和血液指标。试验将二十四头八周龄的断奶猪分成两组。每组随机分配到不同的养猪单元。两组的动物管理和饲喂方式保持一致。试验持续了 120 天,在此期间对猪的生长性能、摄入营养的消化率以及生化和血液学参数进行了评估。结果表明,DLW 猪的增重(46.56±5.19 千克)明显高于 BLP 猪(34.02 千克),饲料转化率在统计上相似。除了白蛋白(DLW 明显高于 BLP)和尿素(BLP 明显高于 DLW)之外,各品种之间在总蛋白、胆固醇、球蛋白、甘油三酯、肌酐、谷草转氨酶和谷丙转氨酶以及血液学参数方面没有显著差异(p > 0.05)。然而,外来大龙虾的平均血小板和白细胞浓度相对较高。虽然 BLP 的粪氮较高,DLW 的尿氮较低,但两个品种的尿氮、粪氮和总排泄氮均存在显著差异(p < 0.05)。与 DWL 相比,BLP 的营养物质消化率得分最低,但粗纤维除外。这项研究的结果表明,与外来猪种相比,喀麦隆本地猪在使用当地原料配制的日粮和改善饲养条件的情况下具有更高的生产率。这表明,当局应努力促进和重视本地猪的饲养,以补充外来猪种,从而加强喀麦隆的养猪业。
