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
