“…The lower excreta Zn concentrations from the Zn imprinted broiler chicks reflect the ability of broiler chicks to adapt to a low Zn diet. This is associated with increased Zn absorption, and the reduction in the excreta Zn content to conserve and maintain normal Zn levels for vital functions in the body (Attia et al, 2013). …”

The goal of this study was to determine the effects of feeding a zinc (Zn) deficient diet to broiler chicks for 96 h post-hatch followed by feeding diets with different Zn sources and supplemental levels (5 to 21 d) on the growth performance, tissue, and excreta Zn content. At the start of the study, four hundred 20-day-old male broiler chicks were divided into two groups. One group was fed a corn soybean meal based diet containing 25 mg of Zn/kg (imprinting diet, ID). The second group was fed the basal diet supplemented with 40 mg of Zn/kg from Zn oxide (ZnO) (non-imprinting diet, NID). Both groups were fed these diets for 96 h. At d 5, chicks from each group were randomly assigned to the dietary treatments consisting of the basal diet alone or the basal diet supplemented with 8 or 40 mg/kg Zn as ZnO or Zn proteinate. Main effects of post-hatch Zn ID were observed on feed intake and G:F. ID decreased (P < 0.05) feed intake and improved (P < 0.05) the gain to feed ratio (G:F) of 14 and 21 d old chicks compared to G:F of chicks fed NID. Additionally, G:F for 14 and 21 d was improved (P < 0.05) by interaction of Zn source × level. Furthermore, at d 21 chicks fed the ID had a lower (P < 0.05) Zn content in the tibia ash and excreta, and a higher (P < 0.05) Zn content in the pancreas tissue compared to chicks fed NID. These results suggest that Zn imprinting can affect body Zn stores and early performance.

This study aims to utilise thyme oil (TO) as a natural growth promoter in comparison to mannanoligosaccharides (MOS) for broilers raised under hot climates from 1 to 28 days of age. Thus, a total of 180, day-old broilers chicks were divided into five groups (36 broilers/group in 6 replicates of 6 broilers/replicate). The chickens were fed the same corn-soybean meal basal diet and were submitted to one of the following five dietary treatments: (a) positive control group, fed the basal diet supplemented with MOS at 1g/kg feed; (b) negative control group, fed the basal diet without supplementation; (c) thyme oil 1.0 (TO_1.0) group fed TO at 1.0 g/kg feed, (d) thyme oil 1.5 (TO_1.5) group fed TO at 1.5 g/kg feed and (e) thyme oil 2.0 (TO_2.0) group fed TO at 2.0 g/kg feed. The TO_1.0 displayed a better feed conversion ratio (FCR) than did the other treatments (p < .01). The MOS, TO_1.5 and TO_2.0 groups had higher (p < .01) plasma total protein than the control, and TO_1.5 also increased plasma globulin (p < .01) compared to the control, but decreased plasma albumin/globulin ratio. Moreover, the TO groups significantly decreased the plasma AST. Groups on the MOS and TO_1.0 diets showed higher (p < .01) white blood cells (WBCs) than the other groups. In addition, the MOS and TO_2.0 groups exhibited a greater (p < .01) antibody titre to infectious bursa disease (IBD) than the control group. In conclusion, TO at 1.0 g/kg diet may be used as a potential growth enhancer for broilers in hot region during 1-28 days.ARTICLE HISTORY

This study was conducted to investigate the performance of crossbreed Korean native ducks for production of Korean native commercial ducks which are adapted to Korean environment. A total of four hundred eighty ducklings (1-d-old) of crossbreds from A and B lines (derived from National Institute of Animal Science) were used in this work and divided into 8 treatments (4 replicates/group, 15 birds/replicate) with 4×2 factors (4 groups, AA, AB, BB, BA; 2 genders, male and female). Ducks were fed diets based on corn-soybean meal for 0 to 3 wk (22.0% [CP], 2,904 kcal/kg [ME]) and 3 to 8 wk (18.0% [CP], 3,002 kcal/kg [ME]). Body weight of AA group was higher than BB and BA groups (P<0.05), but there was no significant difference on body weight at 8 wk old. Body weight gain of AB group was the highest among groups (P<0.05), but there was no significant difference on body weight gain among crossbreds at 0∼3, 3∼8 and 0∼8 wk old. On body weight gain, feed intake, and feed conversion ratio, male was higher than female at the age of 3 and 8 wk old (P<0.05, P<0.01). There was no significant difference on uniformity and livability. However, production index of male was higher than that of female (P<0.01). These results may provide the basic data on growing performance and productivity of crossbreed Korean native ducks for the production of commercial Korean native duck.
