The study aimed to evaluate the influence of wheat straw and different coffee husk (CHs) levels in pellet bedding on its quality, broiler chickens' performance, meat quality, and welfare indicators. In total, 200 Ross 308 chickens were divided into 4 groups: C - control with wheat straw pellet; CH10 - pellet with 10% CHs, CH25 - pellet with 25% CHs, and CH50 - pellet with 50% CHs. During 42 days of rearing, each bedding's physicochemical features were analyzed. The production results were controlled, and the footpad dermatitis, hock burns, and feather quality were assessed. From chosen birds, carcass composition was analyzed, as well as the qualitative features (color, water-holding capacity, drip loss) and breaking bone strength.
The bedding material and rearing days influenced the content of dry matter, crude fiber, nitrogen, phosphorus, potassium, NDF, ADF, and pH. The results were inconclusive. The increasing trends in nitrogen, phosphorus, and potassium content were noticed at the end of rearing. Strong coefficient determination in bedding features was found (0.580 - 0.986). The pellet with CHs had no adverse effect on the growth performance of broilers. In the CH50 group, a lower fat percentage was found. A beneficial effect on water-holding capacity was noticed in leg muscles from CH10 and pectoral muscles from CH25. A significant decrease was found in footpad dermatitis incidence in groups CH25 and CH50.
It can be concluded that CHs reuse in broilers as the pellet bedding material is possible due to the beneficial effect on some meat quality features and no adverse effect on the performance of broiler chickens. The positive impact on lower foot pad dermatitis incidence indicated the possibility of using CHs in pellet bedding.
本研究旨在评估小麦秸秆和不同咖啡壳（CHs）水平对颗粒状垫料质量、肉鸡生产性能、肉质和福利指标的影响。共选用 200 只罗斯 308 肉鸡分为 4 组：C-对照组，使用小麦秸秆颗粒；CH10-组，使用 10% CHs 的颗粒；CH25-组，使用 25% CHs 的颗粒；CH50-组，使用 50% CHs 的颗粒。在 42 天的饲养期间，分析了每种垫料的物理化学特性。对生产结果进行了控制，并评估了脚垫皮炎、跗关节烧伤和羽毛质量。从选定的鸡中分析了屠体组成，以及定性特征（颜色、保水性、滴水损失）和骨折强度。
垫料材料和饲养天数影响了干物质、粗纤维、氮、磷、钾、NDF、ADF 和 pH 的含量。结果并不确定。在饲养结束时，氮、磷和钾的含量呈上升趋势。发现垫料特性的系数决定度较高（0.580-0.986）。在 CH50 组中，发现脂肪百分比较低。在 CH10 组的腿部肌肉和 CH25 组的胸部肌肉中发现了保水性的有益效果。CH25 和 CH50 组的脚垫皮炎发生率显著降低。
可以得出结论，由于对一些肉质特征有有益影响，并且对肉鸡的生产性能没有不利影响，因此可以将 CHs 重新用作肉鸡的颗粒状垫料。较低的脚垫皮炎发生率表明使用 CHs 作为颗粒状垫料是可能的。
