Des enzymes exogènes et des additifs alimentaires phytogènes sont proposés en alternative aux antibiotiques utilisés comme promoteurs de croissance dans la production de volaille. Cette étude a évalué l’effet de l’incorporation de farine de feuilles de papaye (FFP) et de la supplémentation en enzymes (E) dans le régime alimentaire des poulets de chair. Au total, 288 poulets de chair Arbor Acre d’un jour ont été utilisés. Quatre régimes alimentaires ont été formulés pour être isocaloriques et isoprotéiques : régime 1, témoin (0 % FFP, 0 % E), régime 2 (0 % FFP, 0,05 % E), régime 3 (5 % FFP, 0 % E) et régime 4 (5 % FFP, 0,05 % E). Chaque régime a été répliqué six fois avec 12 poulets dans chaque lot. E a amélioré (p < 0,05) le gain de poids à trois semaines. La digestibilité de la matière sèche (MS), des protéines brutes (PB), des matières grasses et des cendres a été améliorée (p < 0,05) avec E, alors que l’incorporation de FFP a augmenté (p < 0,05) la digestibilité de la MS et des PB. L’interaction E x FFP a été significative (p < 0,05) pour la digestibilité de la MS et des PB. E a amélioré (p < 0,05) le poids à l’abattage et a diminué le poids du foie. Les plaquettes sanguines ont varié selon les régimes et ont augmenté (p < 0,05) avec E. E a réduit (p < 0,05) les lipoprotéines de basse densité (LDL), alors que FFP a réduit (p < 0,05) le cholestérol et les LDL. En conclusion, l’association de E et de FFP a amélioré la croissance des poulets, et la supplémentation en enzymes ou en FFP serait bénéfique pour la santé des poulets.

“…But the findings of Olumide et al (2022) contradict the current findings and revealed that diet supplementation with inclusion level of papaya seed meal from 0.10 to 0.25% significantly increased feed intake of broilers compared with birds that had non-supplemented diet. However, the numeric increase in feed intake of birds that may be due to the consequence of the faster growth of birds caused by PLES in drinking water, which resulted in higher nutritional requirements (Hossain et al 2016); usually increase feed intake of birds in order to meet their nutritional requirements (Shrivastava et al, 1981). The cumulative feed conversion ratio (FCR) of birds in different treatments revealed that there was a gradual increasing trend observed with age of birds but the differences between the treatments was non-significant.…”

This study was conducted to investigate the effect of supplementing papaya leaf extract (PLES) in drinking water on growth performance, carcass characteristics, meat quality and serum biochemistry parameters of broiler chickens from 0 to 37 days of age in corn-soybean based diet. A total of 520 unsexed one-day-old Cobb-500 broiler chicks were randomly assigned to five treatment groups, with four replicates having twenty-six chicks in each group. Treatment groups were as follows: 0.00, 0.5, 1.00, 1.5 and 2.00 cc of PLES in 1000 ml of drinking water, respectively. The pre-starter, starter and grower diet were fed from 0 to 11, 12 to 26 and 27 to 37 days of age. Body weight, weight gain, feed intake, feed conversion ratio and broiler production efficiency factor (BPEF) were measured for 37 days. Carcass, meat quality and serum biochemical parameters were also measured. The results of the present study showed that non-significantly greater body weight, weight gain and broiler production efficiency factor (BPEF) were observed in PLES groups than control. There was no significant difference in feed intake and feed conversion ratio of broiler chickens in the treatment groups. The relative proportion of dressing characteristics and meat quality in terms of drip loss, cooking loss of breast meat did not alter significantly between the treatments. However, total cholesterol in serum tended (P<0.10) to be reduced in the treated groups than control but other (albumin, total protein, high-density lipoprotein) were not influenced by the treatments. Taken together, our results indicate that papaya leaf extract in drinking water can be supplemented as phytobiotic additive to accelerate growth and improve health status of broiler chickens without any adverse effect.

Effect of dietary cassava peel meal supplemented with methionine and multienzyme on hemo-biochemical indices, digestibility, and antioxidants in rabbits

Background The effects of cassava peel meal (CPM) supplemented with methionine (MET) and multienzyme (ENZ) was studied using 240 5-week-old rabbits in a completely randomized design arranged in 2 × 2 × 2 factorial (2 CPM levels, 0 and 350 g/kg; 2 methionine levels, 5.6 and 8.3 g/kg; and 2 enzyme levels, 0 and 0.5 g/kg). Results The CPM inclusion reduced (P < 0.05) leucine, lysine, valine, and threonine digestibility, while the digestibility of leucine, lysine, and valine increased (P < 0.05) by high methionine level. Multienzyme increased leucine, lysine, and valine digestibility. CPM reduced (P < 0.01) red blood cell (RBC) count and the total serum protein. Higher methionine supplementation increased the serum total protein by 9.2%. The CPM inclusion increased bilirubin, alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Methionine and enzyme supplementation increased albumin (ALB) but reduced creatinine (CRE). Superoxide dismutase, glutathione peroxidase, and catalase activity level increased (P < 0.01) with methionine and enzyme supplementation. Conclusion Cassava peel meal could be included in growing rabbits’ diets at 350 g/kg level with methionine at 32.53% higher than requirement and 0.5-g/kg multienzyme supplementation.
