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
