Oral supplementation of Jackfruit (Artocarpus heterophyllus) leaf extract to broiler chickens

This study examined the impact of Jackfruit Leaf Extract (JLE) supplementation on broiler chicken performance, gut health, and meat quality as a potential alternative to antibiotic growth promoters. One hundred forty-four day-old Arbor Acre broiler chicks were randomly assigned to four groups, receiving JLE in their drinking water at concentrations of 0, 1, 3, and 5 mL/L for 17 days. The variables included in each file and description of the parameter is as follows: File 1: W1 = initial weight (kg) NOB1 = Number of birds weighed per replicate at day 1 of experiment W7 = weight at day 7 (kg) NOB7 = Number of birds weighed per replicate at day 7 W14 = weight at day 14 (kg) NOB14 = Number of birds weighed per replicate at day 14 W17 = final weight at day 17 (kg) NOB17 = Number of birds weighed at day 17 AIW = Average initial weight AFW = Average final weight at day 17 TWG = Total weight gain ADWG = Average daily weight gain Average initial weight (g/bird) = W1/NOB1 Average final weight at day 17 (g/bird) = W17/NOB17 Total weight gain = AFW -AIW Average daily weight gain (g/bird/day) = TWG/duration of experiment (17 days) File 2: NOB = Number of birds per replicate TFI (kg) = Total feed intake for 17 days ADFI = Average daily feed intake TFI (g) = TFI (kg) × 1000 ADFI (g/bird/day) = TFI (g) / (NOB × 17 days) File 3: NOB = Number of birds per replicate TWI (l) = Total water intake for 17 days ADWI = Average daily water intake TWI (ml) = TWI (l) × 1000 ADWI (ml/bird/day) = TWI (ml) / (NOB × 17 days) File 4: AIW = Average initial weight (g/bird/day) AFW = Average final weight at day 17 (g/bird/day) ADWG = Average daily weight gain (g/bird/day) ADFI = Average daily feed intake (g/bird/day) ADWI = Average daily water intake (ml/bird/day) FCR = Feed Conversion ratio File 5: Escherichia coli (Log 10 CFU/g) Enterococcus spp (Log 10 CFU/g) Lactobacillus spp (Log 10 CFU/g) Staphylococcus spp (Log 10 CFU/g) File 6: Live weight (g), Dressed weight (g), BREAST (g), BACK (g), THIGHS (g), DRUMSTICKS (g), WINGS (g), NECK (g), THYMUS (g), BURSA OF FABRICIUS (g), HEART (g), SPLEEN (g), LUNGS (g), PANCREAS (g), GIZZARD (g), LIVER (g), PROVENTRICULUS (g), DUODENUM WEIGHT (g), JEJUNUM WEIGHT (g), ILEUM WEIGHT (g), CAECA WEIGHT (g), COLON WEIGHT (g), DUODENUM LENGTH (cm), JEJUNUM LENGTH (cm), ILEUM LENGTH (cm), CAECA LENGTH (cm), COLON LENGTH (cm) File 7: pH24, COLOR (color fan), Dry matter (%), ASH (%), Crude Protein (%), Ether extract (%) Sensory: appearance, flavour, chewiness, saltiness, overall acceptability本研究探究了菠萝蜜叶提取物（Jackfruit Leaf Extract, JLE）作为抗生素生长促进剂的潜在替代品，对肉鸡生产性能、肠道健康及肉品质的影响。将144只1日龄爱拔益加（Arbor Acre）肉鸡雏鸡随机分为4组，分别在饮水中添加浓度为0、1、3、5 mL/L的JLE，试验周期为17天。各文件包含的变量及参数说明如下： File 1: W1 = 初始体重（kg） NOB1 = 试验第1天每个重复组称重的肉鸡只数 W7 = 第7天体重（kg） NOB7 = 试验第7天每个重复组称重的肉鸡只数 W14 = 第14天体重（kg） NOB14 = 试验第14天每个重复组称重的肉鸡只数 W17 = 试验第17天终末体重（kg） NOB17 = 试验第17天称重的肉鸡只数 AIW = 平均初始体重 AFW = 试验第17天的平均终末体重 TWG = 总增重 ADWG = 平均日增重 平均初始体重（g/只）= W1/NOB1 试验第17天平均终末体重（g/只）= W17/NOB17 总增重 = AFW - AIW 平均日增重（g/只·天）= 总增重 / 试验周期（17天） File 2: NOB = 每个重复组的肉鸡只数 TFI (kg) = 17天总采食量（kg） ADFI = 平均日采食量 TFI (g) = TFI (kg) × 1000 ADFI (g/只·天) = TFI (g) / (NOB × 17天) File 3: NOB = 每个重复组的肉鸡只数 TWI (l) = 17天总饮水量（L） ADWI = 平均日饮水量 TWI (ml) = TWI (l) × 1000 ADWI (mL/只·天) = TWI (mL) / (NOB × 17天) File 4: AIW = 平均初始体重（g/只·天） AFW = 试验第17天平均终末体重（g/只·天） ADWG = 平均日增重（g/只·天） ADFI = 平均日采食量（g/只·天） ADWI = 平均日饮水量（mL/只·天） FCR = 饲料转化率（Feed Conversion Ratio） File 5: 大肠杆菌（Escherichia coli）(Log 10 CFU/g) 肠球菌属（Enterococcus spp）(Log 10 CFU/g) 乳杆菌属（Lactobacillus spp）(Log 10 CFU/g) 葡萄球菌属（Staphylococcus spp）(Log 10 CFU/g) File 6: 活体重（g）、屠体重（g）、胸肉（BREAST）重（g）、背肉（BACK）重（g）、大腿肉（THIGHS）重（g）、鸡腿（DRUMSTICKS）重（g）、翅肉（WINGS）重（g）、颈肉（NECK）重（g）、胸腺（THYMUS）重（g）、法氏囊（BURSA OF FABRICIUS）重（g）、心脏（HEART）重（g）、脾脏（SPLEEN）重（g）、肺脏（LUNGS）重（g）、胰腺（PANCREAS）重（g）、肌胃（GIZZARD）重（g）、肝脏（LIVER）重（g）、腺胃（PROVENTRICULUS）重（g）、十二指肠（DUODENUM）重量（g）、空肠（JEJUNUM）重量（g）、回肠（ILEUM）重量（g）、盲肠（CAECA）重量（g）、结肠（COLON）重量（g）、十二指肠（DUODENUM）长度（cm）、空肠（JEJUNUM）长度（cm）、回肠（ILEUM）长度（cm）、盲肠（CAECA）长度（cm）、结肠（COLON）长度（cm） File 7: pH24（24小时pH值）、肉色（COLOR，色卡法）、干物质（Dry matter，%）、灰分（ASH，%）、粗蛋白质（Crude Protein，%）、粗脂肪（Ether Extract，%） 感官指标：外观、风味、咀嚼性、咸度、总体可接受性
