Effects of different levels of two types of olive pulp with or without exogenous enzyme supplementation on broiler performance and economic parameters

The effects of the dietary inclusion of olive pulp (OP) and supplementation birds with a commercial enzyme blend (ENZ) on the performance of broilers were evaluated. Six hundred one-day-old male Ross 308 broilers were divided according to a completely randomized design into 10 treatments in a 2×2×2+2 factorial arrangement, consisting of two olive pulp levels (50 and 100 g/kg diet), two pulp categories (processed and non-processed), the inclusion or not of an enzyme blend supplement, and two control treatments without OP and the inclusion or not of the enzyme blend in the diet. Feed intake (FI), weight gain (WG), feed efficiency (FE), energy intake (EI), energy efficiency (EE), protein intake (PI), protein efficiency (PE), feed cost per kg live weight (FC/kg), and production index (IP) were determined. There was no significant difference (p> 0.05) between broilers fed the OP diets and the control diets for all parameters. Processed OP improved FE (p 0.019 from 1-21 days; p 0.005 from 22-42 days; and p 0.008 from 1-42 days of age) and EE (p 0.05) any of the studied variables. The inclusion of OP in the diets at levels up to 100g/kg would does not have deleterious effects on broiler production performance.

The enzyme blend supplementation did not influence (p> 0.05) any of the studied variables.

Effects of Different Dietary Rosmarinus Officinalis Powder and Vitamin E Levels on the Performance and Gut Gross Morphometry of Broiler Chickens

ABSTRACT The main objective of the present study was to evaluate the effects of the dietary addition of different levels of rosemary powder (RP) and vitamin E (VitE) on broiler performance and gut gross morphometry. A total of 270 one-day-old Ross 308 male chicks were randomly assigned to nine dietary treatments with three replicates of10 birds each. Treatments consisted of diets were supplemented with 0, 0.5 or 1.0% RP and 0, 100 or 200 mg/kg VitE (alpha-tocopherol acetate). Feed intake and weight gain were recorded weekly. On day 42, one bird per replicate was euthanized after blood sampling. Gastrointestinal tract segments were measured and/or weighed. Means were compared by least significant difference. Overall, broilers fed1.0% RP presented lower (p 0.05) feed intake, weight gain, and final weight body than those fed 0.5% RP. Broilers fed the 0.5% RP plus 200 mg/kg VitE diet presented higher weight gain (p 0.05) in than those in the control group (0% RP and 0 mg VitE). Jejunum length and weight, colon length and width, and right cecum weight were also negatively affected (p 0.05) by the 1.0% RP diet when compared with the 0.5% RP diet. We suggest that the dietary supplementation of 0.5% RP plus 200mg/kg of vitE improves broiler performance and does not have significant adverse effects on gross gut morphometry. Dietary VitE may play a potential protective role against the negative effects of high levels of RP.

Effects of Different Dietary Levels of Two Types of Olive Pulp and Exogenous Enzyme Supplementation on the Gastrointestinal tract size, Immunology and Hematology of Broilers

ABSTRACT The effects of the dietary inclusion of olive pulp (OP) and the supplementation of a commercial enzyme blend (ENZ) on the gastrointestinal tract (GIT) size, and immune and hematological parameters were evaluated. In total, 600 one-day-old Ross 308 male broiler chicks were divided into 6 treatments according to a completely randomized design, in a 2×2×2 factorial scheme, consisting of the dietary inclusion of two olive pulp levels (50 and 100 g/kg in diet), two pulp categories (processed and unprocessed), and the inclusion or not of an enzyme blend. On d 42, birds were euthanized and blood samples were collected, and lymphoid, hematologic, and GIT organs were measured. The inclusion of 100g/kg OP in the diets increased jejunum relative weight (J%) and jejunum length (p 0.05). Processed OP reduced jejunum weight and length, J%, and left cecum length, serum triglycerides and VLDL cholesterol levels (p 0.05). Enzyme supplementation did affect any of the studied parameters (p>0.05). The OP inclusion improved the GIT size, while processed OP reduced GIT measurements and serum lipid levels.
