“…These results agreed with similar studies that examined the changes in blood biochemistry parameters in laying hens fed diets with varying concentrations of olive pulp with or without -mannanase enzyme supplementation (Zangeneh & Torki, 2011;Sayehban, 2015;Sayehban, 2016).…”

This study investigated the growth performance, carcass characteristics, blood biochemistry, humoral immunity and caecal microbiota of broiler chicks fed 0, 2, 4, 6, and 8% olive meal (OM) in diet. In addition, this study investigated the use of enzymatic feed supplements (β-glucanase, phytase and hemicellulase) to enhance digestibility of high fibre diets. At the end of the feeding period (42 days), there were no significant differences among dietary groups on broiler growth performance, including bodyweight (BW) and bodyweight gain (BWG), feed intake (FI), and feed conversion efficiency (FCE). The evaluated carcass traits and meat cuts (breast, drumsticks and wings) did not vary among dietary treatments. Although some minor differences were observed in blood albumin and cholesterol concentrations among groups, the cecum microbiota did not differ in broilers. Antibody titers following vaccinations against infectious bronchitis virus (IBV) and Gumboro disease were higher in birds fed 4% OM. Adding supplemental enzymes to diet had minimal effect on the parameters. Findings from this study support the literature, which suggests that OM is a suitable feed byproduct in broiler diets. Moreover, including OM in poultry rations has the potential to provide an economic and environmentally friendly alternative to traditional diets. Finally, the current trial identified that the addition of enzymes was not necessary to achieve optimal productive performance in broiler fed diet containing OM. ______________________________________________________________________________

“…In the present study, the determined values of several biochemical parameters examined were in line with normal values (Campbell, 2004) indicating that good health is maintained when olive pulp is added into broiler diets. Similarly, Sayehban et al (2015) reported that processed olive pulp fed to broiler diets had no effect on hematological parameters. In contrast, Al-Harthi (2015) reported that plasma albumin was increased when olive cake was added to layer diets at 10 and 20% compared to control.…”

Olive oil production generates various by-products that can be used in animal nutrition. These by-products contain several polyphenolic compounds that may exhibit antioxidant properties. The present study was designed to evaluate the effects of adding olive pulp to the feed on broiler performance, carcass yield and antioxidant enzymes. Two hundred (200), as hatched, day-old, Cobb 500 broilers were reared in total for 42 days. There were 4 dietary treatments. In T1 treatment, no olive pulp was added to starter, grower and finisher diet. In T2 treatment, olive pulp was added to starter, grower and finisher diet at a level of 0, 2.5 and 5% respectively. In T3 treatment, olive pulp was added to starter, grower and finisher diet at a level of 0, 5 and 5% respectively. In T4 treatment, olive pulp was added to starter, grower and finisher diet at a level of 0, 5 and 8% respectively. Performance, carcass yield and a number of biochemical parameters were examined. Oleuropein and hydroxytyrosol were present in the olive pulp at 952 and 216 mg/kg respectively. Broilers performed well and no differences were observed between treatments on final body weight, carcass yield, total antioxidant activity and expression of selected antioxidant enzymes. Discriminant analysis was further applied and revealed that samples clustered according to added level of olive pulp. Samples from broilers fed T2 and T3 diet were located in the middle of the plot away from other treatments exhibiting high values of carcass, breast yield and most of the antioxidant enzyme activities. In conclusion, olive pulp can be used up to 5% in diets of broilers and future studies conducted on-farm conditions may pronounce its impact on growth performance and antioxidant potential.
