“…Pen basis egg production was recorded and collected throughout the experiment. Hen-day egg production, egg mass and feed efficiency were calculated according to methods described by Ali et al [10] and Singh et al [11]. Eggs were labeled and collected separately on weeks 2, 4, 6, and 8 for egg quality analysis.…”

Objective: An experiment was conducted to investigate the response of laying hens fed corn distiller' s dried grains with solubles (DDGS) that are naturally contaminated with deoxynivalenol (DON). Methods: One hundred and sixty 52-week-old Lohmann Brown Lite hens were randomly allotted to five dietary treatments with 8 replicates per treatment. The dietary treatments were formulated to provide a range of corn DDGS contaminated with DON from 0% to 20% (i.e., 5% scale of increment). All laying hens were subjected to the same management practices in a controlled environment. Body weight, feed intake and egg production were measured biweekly for the entire 8-week experiment. The egg quality was measured biweekly for 8 weeks. On weeks 4 and 8, visceral organ weights, blood metabolites, intestinal morphology, and blood cytokine concentrations were measured. Results: The inclusion of corn DDGS contaminated with DON in the diet did not alter (p> 0.05) the body weight, feed intake, hen-day egg production, egg mass and feed efficiency of the laying hens. No difference was found (p>0.05) in the egg quality of hens that were fed the dietary treatments. Furthermore, hens that were fed a diet containing corn DDGS contaminated with DON showed no change (p>0.05) in the visceral organ weights, the blood metabolites, and the cytokine concentrations. The crypt depth increased (p<0.05) as the amount of corn DDGS contaminated with DON increased. Proportionately, the villus height to crypt depth ratio of the laying hens decreased (p<0.05) with the increasing level of corn DDGS contaminated with DON in the diet. Conclusion:The inclusion of corn DDGS contaminated with DON up to 20% in layer diets did not cause changes in egg production performance and egg quality, which indicates that DON is less toxic at the concentration of 1.00 mg DON/kg.

Abstract. Zalizar L, Winaya A, Malik A, Widodo W, Suyatno, Anggraini AD. 2021. Species identification and prevalence of gastrointestinal helminths in Indonesian native chickens, and its impact on egg production. Biodiversitas 22: 4363-4369. Gastrointestinal parasite (GIP) infection is a severe problem of local chicken production, such as poultry and egg. Hence, the proper strategy to control the parasite invasion should be implemented regarding chicken productivity performance. Moreover, the existing environment is also essential in supporting chicken production. The study's objective was to determine the prevalence rate of the gastrointestinal helminths in four strains of Indonesian native chicken viz. Ranupane, Lokal Putih, Wareng, and Lurik, and the impact of the chicken egg production. A total of 280 chickens which were evaluated consisting of 70 birds from each strain, were tested for the prevalence of helminths eggs in a sample of feces and the effect on hen day production (HDP). The results showed that the percentage rates of infected chicken with helminths reached 56.43%, and the number of eggs per gram (EPG) in all four strains was considered moderate (115 EPG of feces). At the same time, the average of HDP per the four strains at 7 to 12 months was about 34.36-45.80%, which was in a normal range. The majority of helminths species found in examined native chicken were Ascaridia galli, Heterakis gallinarum, Raillietina spp., and Capillaria spp. The prevalence of GIP helminths did not negatively affect egg production in all four strains of chicken by moderately tolerant infections, and the HDP of chickens was normal.
