Variation of mortality rate according to the level of biosecurity in broiler farms (n = 153) in four regions of Cameroon (North, Adamawa, East and Centre), 2024

Production phase	Poor biosecurity (n = 63)	Good biosecurity (n = 90)	P-value
Starter (d1-15)	2.23 ± 1.88a	1.43 ± 0.98b	0.003
Grower (d16-30)	2.26 ± 1.86a	1.47 ± 1.25b	0.008
Finisher (d 31- 45)	1.94 ± 1.26a	1.51 ± 1.20a	0.217
Total (d1-45)	4.63 ± 3.19a	2.89 ± 2.01b	< 0.001

For the same production phase, values with different letters of the alphabet (a, b) are significantly different at p = 5% , d1–15: Day one to day 15 of the production phase
