The purpose of this study was to evaluate the effect of full-fat almonds (FFA) as an alternative protein and fat source for broiler feed on broiler productivity, nutrient digestibility, blood characteristics, cecal-fecal microflora, and foot-pad dermatitis (FPD). A total of 96, one-day-old broiler chickens (Arbor Acres) with initial body weight 41.61 ± 0.36 g were placed in 16 cages. In each trial, four treatments were set up: a basal diet partially replacing animal fat with FFA 0% (Control, CON), a basal diet partially replacing animal fat with FFA 1% (T1), a basal diet partial replacing animal fat with FFA 2% (T2), a basal diet partially replacing animal fat with FFA 4% (T3). The experiment was conducted for a total of 4 weeks. Feed conversion ratio (FCR) was higher ( < 0.05) in the T3 group of broilers at weeks 0 to 1 than in the CON group of broilers. From weeks 3 to 4, and for the entire experimental period, FCR was lower ( < 0.05) in the T3 group of broilers than in the CON and T1 groups of broilers. The apparent ileal digestibility (AID) of the ether extract (EE) was higher ( < 0.05) in the T3 group than in the other treatment groups, and AID of crude protein (CP) was higher ( < 0.05) in the T3 group than in the CON group. The apparent total tract digestibility (ATTD) of EE was lower ( < 0.05) in the CON group than in the other treatment groups, and the ATTD of CP and energy was higher ( < 0.05) in the T3 group of broilers than in the CON group of broilers. The AID and ATTD of total amino acids were higher ( < 0.05) in the T3 group than in the other treatment groups. Blood cholesterol levels were lower ( < 0.05) in the T3 group of broilers than in the CON and T1 groups of broilers, and higher ( < 0.05) in the CON group of broilers than in the T2 and T3 groups of broilers. The amount of in the cecal and fecal was lower ( < 0.05) in the T3 group than in CON and T1 groups. FPD score was higher ( < 0.05) in the T3 group of broilers than in the CON group of broilers. In conclusion, replacing a partial of animal fat with at least 4% FFA in broiler diets can increase growth performance and nutrient digestibility in broiler nutrition.
本研究的目的是评估全脂杏仁(FFA)作为肉鸡饲料中替代蛋白质和脂肪来源对肉鸡生产性能、养分消化率、血液特性、盲肠粪便微生物群和脚垫皮炎(FPD)的影响。总共96只1日龄的肉鸡(艾维茵),初始体重41.61±0.36克,被安置在16个笼子里。在每次试验中,设置了四种处理:基础日粮中用0%FFA替代动物脂肪(对照组,CON),基础日粮中用1%FFA替代动物脂肪(T1),基础日粮中用2%FFA替代动物脂肪(T2),基础日粮中用4%FFA替代动物脂肪(T3)。实验总共进行了4周。在第0至1周,T3组肉鸡的饲料转化率(FCR)高于CON组肉鸡(P<0.05)。从第3周至第4周以及整个实验期,T3组肉鸡的FCR低于CON组和T1组肉鸡(P<0.05)。T3组的乙醚提取物(EE)表观回肠消化率(AID)高于其他处理组(P<0.05),T3组的粗蛋白(CP)AID高于CON组(P<0.05)。CON组的EE表观全肠道消化率(ATTD)低于其他处理组(P<0.05),T3组肉鸡的CP和能量ATTD高于CON组肉鸡(P<0.05)。T3组的总氨基酸AID和ATTD高于其他处理组(P<0.05)。T3组肉鸡的血液胆固醇水平低于CON组和T1组肉鸡(P<0.05),CON组肉鸡的血液胆固醇水平高于T2组和T3组肉鸡(P<0.05)。T3组盲肠和粪便中的大肠杆菌数量低于CON组和T1组(P<0.05)。T3组肉鸡的FPD评分高于CON组肉鸡(P<0.05)。总之,在肉鸡日粮中用至少4%的FFA替代部分动物脂肪可提高肉鸡营养中的生长性能和养分消化率。
