In this study, we have observed different technological processes, which are commonly used in poultry production. Rations contained different amounts of barley and multi-enzyme, egg weight, egg mass, egg yield, feed intake, egg weight. The rations of the control groups were as follows: 0% barley (based of corn) (K), 15% untreated barley (A1), 15% pellet barley (A2), 15% flaked barley (A3), 30% untreated barley (A4), 30% pelleted barley (A5), 30% flaked barley (A6), 30% untreated barley + enzyme (0. 025%) (A7). In the research, 64 brown laying hens ATAK-S for 36 weeks were divided into 8 different treatments for egg …

The present study aimed to investigate the substituting effect of sunflower meal (SFM) for soybean meal (SBM) with or without supplemental Avizyme on growth performance, protein and energy efficiency ratios, carcass traits, and nutrient digestibility of broiler chickens. A 4 × 2 factorial design experiment was conducted with four levels of SFM replacing SBM (0%, 25%, 50%, 75%) and two levels of supplemented Avizyme (0 or 0.1 g/kg diet). Results revealed that increasing SFM substitution for SBM up to 50% was associated with an increase in body weight (P < 0.01). Daily weight gain was statistically (P < 0.01) enhanced with increasing SFM up to 50% through 22 to 42 and 7 to 42 days of age. Feed conversion ratio improved (P < 0.01) in groups given SFM at 25% and 50% compared to the control. No carcass values were affected by SFM inclusion or Avizyme. The inclusion of 25% or 50% SFM increased (P < 0.01) protein efficiency at periods of 7?21 and 22?42 days of age. Energy efficiency ratio improved (P < 0.01) due to SFM incorporation at levels of 25% or 50% in all periods. The interaction effect between SFM and Avizyme was not significant on a majority of studied parameters. The digestion coefficients of crude fiber, N-free extract, and organic matter increased (P < 0.05 or P < 0.01) with increased levels of SFM. In conclusion, the incorporation of SFM as a substitute for SBM in broiler diets improved the growth performance of broilers. The use of SFM up to 50% without Avizyme supplementation could be recommended in broiler diets from 7 to 42 days of age.

This study was conducted to investigate the effects of diet and exogenous enzymes on growth responses and micronutrient digestibility of broilers. Day-old broilers (n = 256) were distributed into a 2 x 2 factorial design and were fed on two basal diets: soybean (T1) or canola (T2) meals as such, or supplemented with enzymes up to 21 days. Feed intake (FI) and live weight (LW) to 21 days on the T2 diet was higher (P < 0.001) than that on T1. Feed conversion ratio (FCR) was better (P < 0.01) on T1 than on T2 at 21 days. Enzymes generally improved (P < 0.001) FI, FCR, and LW. The digestibility of histidine was higher (P < 0.05) on T2, but lysine digestibility was higher (P < 0.01) on T1 at 21 days. Histidine, threonine, lysine, valine, isoleucine, and phenylalanine digestibility was improved (P < 0.05) in the supplemented diets. Mineral digestibility was unaffected (P > 0.05) by diet, but enzymes increased (P < 0.05) digestibility of P, K, Mn, and Cu at 21 days. The digestibility of Cu, Zn, and Mg was higher (P < 0.05) on T2, whereas Ca digestibility was greater (P < 0.05) on the T1 diet. Broilers' growth responded positively to enzyme diets, probably due to improvement in nutrient digestibility.

Comparison Of The Efficiency Of Concentrated Soluble Recombinant Phospholipase D And Natural Phospholipase D Enzymes, Asli Sakmanoğlu, Osman Ergani̇ş
Turkish Journal of Veterinary & Animal Sciences
Phospholipase D (PLD) is a major virulence determinant of Corynebacterium pseudotuberculosis. Various studies have focused on the expression of recombinant PLD (rPLD) enzyme in different Escherichia coli strains, but generally a high yield of insoluble protein was reported. The aims of this study were to express soluble rPLD by different methods in E. coli. The rPLD and natural PLD (dPLD) enzymes were concentrated using an ultramembrane cassette system after the efficiencies of these concentrated enzymes were compared. The rPLD enzyme was expressed in One Shot®BL21(DE3) E. coli when induced by IPTG in TY medium. Soluble dPLD and rPLD enzyme hemolytic …

Performance And Some Digesta Parameters Of Broiler Chickens Given Low Or High Viscosity Wheat-Based Diets With Or Without Enzyme Supplementation, Mevlüt Günal, Sulhatti̇n Yaşar, John Mike Forbes
Turkish Journal of Veterinary & Animal Sciences
The influence of 2 enzyme supplements for diets based on wheat with high or low viscosity on performance and some intestinal parameters of male broiler chickens were investigated. The experiment was of 2 x 3 factorial design, with 2 types of wheat (high or low viscosity) and 3 enzyme treatments (none, Avizyme 1300-xylanase or Avizyme 1500-amylase). Ileal digesta viscosity was significantly (P < 0.029) higher in birds fed with high viscous wheat than with low viscous wheat. Ileal digesta viscosity (P < 0.001) and dry matter content (P < 0.002) were significantly reduced by both enzyme preparations. Body weight gain, feed intake, dry matter intake, feed conversion ratio, DM retention and wet or dry excreta output were not significantly (P > 0.05) affected by all treatments. There were no significant interactions (P > 0.05) between the effects of wheat type and enzyme supplementation. In conclusion, the supplementation of high or low viscous wheat-based diets with the enzyme preparations of amylase …

Turkish Journal of Veterinary & Animal Sciences
This study was performed to determine the effects of using 40% and 60% triticale with or without enzyme instead of maize on egg production, feed intake, feed efficiency, egg quality and hatchability in laying quail diets. In this study, a total of 160, 12-week-old Japanese quails (Coturnix coturnix japonica) were used; birds with similar live weight and production levels were divided into five groups of 32 quails. Although using triticale at the rate of 40% and 60% in the diet of laying quails did not affect egg production, hatchability, fertility, egg specific gravity, egg shell thickness, the egg white and …

Transformation And Stability Of Cloned Polysaccharidase Genes In Gram-Positive Bacteria, Mehmet Sai̇t Eki̇nci̇, Harry J. Flint
Turkish Journal of Veterinary & Animal Sciences
Polysaccharidase genes from rumen bacteria were transferred to and expressed in ruminal and non-ruminal Gram-positive bacteria. The transformation efficiency and genetic stability of polysaccharidase genes in bacteria from different habitats were investigated. PCR amplification of cloned polysaccharidase genes from Escherichia coli, Lactococcus lactis, Enterococcus faecalis, Streptococcus sanguis and S. bovis strain 26 showed that rearrangement of plasmid and the gene fragment did not occur. The DNA band sizes from all primers agreed with the expectations of some transformants of S. bovis JB1 being rearranged. In spite of the rearrangement in S. bovis JB1 polysaccharidase activities were conserved. Growing in the …

Effects Of Enzyme Supplementation To Corn Or Wheat Based Diets Containing Low Energy And Protein On Broiler Chick Performance, Ergün Demi̇r
Turkish Journal of Veterinary & Animal Sciences
Two experiments were carried out in order to determine the effect of corn-soybean meal or wheat-soybean meal based diets containing low energy (DE) and low energy-low protein (DEDP) supplemented with enzyme on the performance of broiler chicks between 0 and 21 days of age. In the first experiment, three diets, namely, control, low energy (DE) and low energy-protein (DEDP) based on corn-soybean meal, were formulated. In the second experiment, control and three diets containing 40% wheat which have normal energy-protein (NENP), low energy (DE) and low energy-protein (DEDP) levels were used. The enzyme was added to the experimental diets, except …

Expression Of Bifunctional Genes Encoding Xylanase And \Beta(1,3-1,4)-Glucanase In Gram-Positive Bacteria, Mehmet Sai̇t Eki̇nci̇, Harry J. Flint
Turkish Journal of Veterinary & Animal Sciences
The xylanase and \beta(1,3-1,4)-Glucanase activities encoding gene from the cellulolytic rumen anaerobe bacterium was cloned into Escherichia/Streptococcus shuttle vector for introduction into Gram-positive bacteria, including the rumen facultative anaerobe bacterium Streptococcus bovis. Activities due to the cloned gene decreased in the stationary phase in batch cultures of S. bovis, reflecting the sensitivity of the cloned enzymes to inactivation in the presence of accumulated lactic acid. Cloned gene activity was detected in the culture supernatant, indicating recognition of the cloned gene signal peptide by Gram-positive bacteria.
