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... |

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... |
