Effects of dietary symbiotic supplementation on growth performance and duodenum histology of Japanese quail (Coturnix coturnix Japonica) reared in different flooring systems R. Bras. Zootec.
Coskun,Isa; Erener,Guray; Cayiroglu,Hayrettin; Altop,Aydin; Cayan,Huseyin; Sahin,Ahmet.
ABSTRACT The objective of this study was to determine the effect of dietary symbiotic supplementation on the growth performance and duodenum histological parameters of quail reared in different flooring systems. A total of 160 mixed-sex healthy quail (47±0.32 g) aged 14 days were used in a 2 × 2 factorial experimental design with four replicates, each including five males and five females. Two flooring systems (wire floor as control and wood shavings bedding) and two dietary treatments (symbiotic supplementation and no supplementation) were tested. Birds were transferred to four-tier cages for the trial. Each kilogram of the commercial diet included 224 g crude protein and 3,080 kcal metabolizable energy. The experiment lasted 21 days. Daily weight gain...

Effects of in ovo injection of lysine and methionine into fertile broiler (parent stock) eggs on hatchability, growth performance, caecum microbiota, and ileum histomorphology R. Bras. Zootec.
Coskun,Isa; Akkan,Aysenur; Erener,Guray.
ABSTRACT We investigated the effect of in ovo injection of lysine, methionine, or their mixture into fertile broiler eggs on hatchability, chick weight, growth performance, inner organ development, caecum total aerobic bacteria, E. coli, coliforms, Enterobactericaea, and ileal histomorphology of broilers. Three hundred fertile eggs obtained from 60-week-old Ross 308 broiler breeders were used. Before this study, a preliminary study was conducted to determine the optimal amino acid dose. Optimum amino acid dose was determined as 2 mg/0.2 mL. Before replacing hatching machine, eggs were weighed individually and numbered. On day 16 of incubation, these eggs were allocated to treatment groups: negative control (no injection), positive control (distilled water...

Evaluation of olive leaf extract as a growth promoter on the performance, blood biochemical parameters, and caecal microflora of broiler chickens R. Bras. Zootec.
Erener,Guray; Ocak,Nuh; Ozturk,Ergin; Cankaya,Soner; Ozkanca,Resit; Altop,Aydın.
ABSTRACT The objective of the study was to examine the effects of an alcoholic liquid olive leaf extract (OLE) obtained from fresh leaves on the growth performance, carcass weight, caecal microflora, and some plasma variables, such as triglycerides, total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) cholesterol in broiler chickens. A total of 375 one-day-old male broilers (Ross 308) were randomly divided into five treatments with five replicate pens (15 birds each) per treatment. The birds were fed either a basal diet with no supplement (control), with 75 (OLE75), 150 (OLE150), 300 (OLE300), and 600 (OLE600) mg kg−1 oleuropein, provided by 0.66, 1.33, 2.65, and 5.32 g kg−1 of the OLE. The dietary supplementation of OLE...
