“…The phytase main effect was significant for all age periods for BWG except at 29–35 D and for FI at 0–14 D, 0–28 D, and 0–35 D, but it was not significant for FCR. Earlier investigators have shown that phytase improved live performance or was associated with a similar performance in response to adequate Ca and P i when it was supplemented in a diet with inadequate Ca and P i ( Singh et al., 2003 , Shaw et al., 2011 , Ceylan et al., 2012 ). The BWG and FI show that phytase was most effective for the first 14 D, and as the bird aged, the phytase effect was not significant.…”

Limestone particle size ( PS ) affects its solubility and thus can influence broiler performance by altering the rate of calcium ( Ca ) release into the gastrointestinal tract. The objective of this research was to determine, using 2 × 2 × 2 factorial arrangement, the influence of PS (fine and coarse) and supplemented phytase (0 and 1,000 FYT/kg) in diets formulated with 2 Ca and P i levels (positive control [ PC ]; negative control [ NC ]) on live performance, bone ash, and apparent ileal nutrients digestibility ( AID ). Starter PC: 0.9 Ca and 0.45 Pi; NC: 0.72 Ca and 0.03 Pi. Grower PC: 0.76 Ca and 0.38 Pi; NC: 0.58 Ca and 0.23 Pi. The 8 diets were assigned randomly to a total of 1,512 birds, with 21 birds per pen and 9 pens per treatment. The main effects of PS and Ca and P i levels had no influence on feed intake ( FI ), body weight gain ( BWG ), or feed conversion ratio. Adding phytase improved BWG by 8 g and 50 g and FI by 25 g and 56 g at 0–14 D ( P ≤ 0.05) and 0–35 D ( P ≤ 0.05), respectively. Interaction between Ca and P i levels and phytase improved BWG and FI for 0–14 D ( P ≤ 0.05) and BWG during 15–28 D ( P ≤ 0.05) for PC without phytase and for PC and NC with phytase when compared with NC without phytase. Birds fed PC without phytase, or either PC or NC with phytase were about 96 g heavier than NC without phytase. Birds fed either PC or NC diet with coarse limestone or PC with fine limestone gained approximately 14 g more ( P ≤ 0.05) than birds fed NC with fine limestone for BWG at 0–14 D ( P ≤ 0.05). Phytase increased tibia bone ash (14 D) by 1% ( P ≤ 0.05). AID of Ca and P i at 14 D was improved ( P ≤ 0.05) by 66% when phytase was added to coarse limestone. Results indicate that phytase improved broiler performance without being affected by PS. Furthermore, phytase had greater influence on coarse limestone than on fine limestone for bone ash and AID. Ca and P i levels were the most influential factors in determining bone ash although phytase inclusion could lead to an improvement during early days.

“…The treatments including RLL increased the disappearance of phytate phosphorus by about 16.6% more than that of the control group, which is in line with the results of Rutherfurd et al (2012), which demonstrated an increase of about 15.8%–19.3% in illegal absorption of phosphate when they used Ronozyme ® in two levels of 1,107 and 2,215 U/kg as a commercial phytase. Furthermore, application of Hostazyme ® in the low P diet decreased the excreta P content of broilers by about 16% (Ceylan, Cangir, Corduk, Grigorov, & Adabi, 2012). Additionally, an improvement in phytate disappearance in the groups fed RLL was about 12.13% higher than the chickens fed LL, indicating the phytase activity of recombinant L. lactis in the gut environment.…”

“…Some studies indicated the positive effects of commercial phytase enzymes on tibia bone mineralization of Ca and P (Ceylan et al, 2012; Driver, Pesti, Bakalli, & Edwards, 2006; Shaw, Hess, Blake, & Ward, 2011). It was reported that the use of recombinant lactobacilli with phytase secretion potential in the broiler chickens enhances Ca and P contents in the tibia bone (Wang et al, 2014).…”

The availability of plant phosphorus in the gut chicken can be improved by increasing phosphorus retention using phytase enzyme or a probiotic with phytase activity as an alternative. In this study, the efficacy of a recombinant probiotic, Lactococcus lactis (L. lactis), with a potential of phytase production was evaluated in broiler chickens. To this aim, 360 one-day-old male broiler Cobb 500 were divided into six treatments with six replicates and reared to 42 days of age. The experimental treatments included positive control diet containing adequate phosphorus (PC), negative control diet containing reduced available phosphorus (NC), negative control diet involving recombinant L. lactis (RLL), negative control diet containing both recombinant L. lactis and Lactobacillus salivarius (RLL + LBS), negative control diet including nonrecombinant L. lactis (LL) and negative control diet containing Hostazym ® . Growth performance, total tract apparent disappearance of phytate-P and nutrient retention, mineral content of the tibia and histomorphology of jejunum were evaluated at the age of 35 days. Based on the results, the phosphorus (P) deficiency in the diet reduced body weight (BW), average daily gain (ADG), length and strength of tibia and increased feed conversion ratio (FCR) compared to PC group. However, the supplementation of Hostazym ® or RLL probiotic into the feed improved BW, ADG, FCR, disappearance of Phytate-P and retention of P, length and strength of the tibia in a level similar to PC treatment. Phosphorus content of tibia in the chickens fed P-deficient diets containing RLL was similar to that of the tibia in the control group. Excreta phytate and total P excretion of the chickens decreased when diets contained Hostazym ® , RLL and RLL + LBS. In addition, the diet containing RLL + LBS probiotic increased villi height compared with other treatments (p < .05). Further, recombinant L. lactis could represent phytase activity in the gut environment of the chickens and could be an alternative to the commercial phytase.

“…When phytase enzyme acts on phytic acid, the availability and the utilization of these nutrients for the chicken´s increases (Sebastain et al, 1998;Ceylan et al, 2012;Cowieson, 2010). Recently, it was reported that using organic elements such as Zn, Mn, Cu and Se in broiler breeders reduced plasma triglycerides, cholesterol, LDL and VLDL (Qiujuan et al, 2012), and it was explained by the role of organic minerals in lipid metabolism by regulating lipoprotein synthesis.…”

“…This phytic acid acts as an anti-nutritional component and, in turn, reduces the utilization of feed (Ceylan et al, 2012). Therefore, many researchers have used phytase enzyme in poultry diets, and some of them have concluded that this enzyme increases the utilization of phytic acid in poultry diets (Tiwari et al,2010).…”

Keywords Broilers, enzymes, olive cake, carcasses parameters, lymphoid organs and lipid metabolism constituents.Submitted: May/2016 Approved: November/2016 ABStRACtAn experiment was carried out to investigate the effect of using olive cake (OC) in broiler diets, when it is supplemented with multienzymes or phytase enzyme. The OC was included in isocaloric, isonitorgneous diets at 5 and 10% levels and fed to broilers from 1-28 days of age. Experimental diets were fed with or without either of the two enzymes: galzym or phytase. This resulted in 3 OC levels (0, 5, 10%) × 3 enzyme supplementations (no enzyme, galzym enzyme, phytase enzyme). This included nine treatments, and each treatment was replicated eight times with seven broiler chickens each. Feed intake, feed conversion ratio, body weight gain, survival rate, dressing, inner and immune organ´s weights (compared to live body weight); and blood lipids constituents were investigated. According to the findings in this study, it could be concluded that OC is a valuable ingredient and might be included in the broiler diet up to 10% without galzym or phytase enzyme addition. Also, further studies should investigate the possibility of using higher ratios of it or mixed with another by-product in poultry diets; as a very cheap by-product. Moreover, these studies can be associated with suitable additives at different concentrations that might help to increase the utilization of olive cake or at least to keep performance equal to the control. On the other hand, it is worthwhile to follow the positive effect of phytase enzyme on cholesterol and very low density lipoprotein (VLDL) concentrations, which may relate it´s use with chicken´s health.
