Anticoccidial and Biochemical Effects of Artemisia Brevifolia Extract in Broiler Chickens

This study was conducted to evaluate the anticoccidial potential of Artemisia brevifolia extract (ABE) and its effect on biochemical parameters against experimental coccidiosis in broiler chickens. For this purpose, a total of 150 broiler chicks were procured and divided into 5 equal groups (30 birds per group). At one week of age, the first three groups (A, B and C) were orally fed with ABE at dose rates of 100, 200 and 300mg/kg respectively for seven consecutive days. Group D served as infected/medicated and was treated with Baycox® (1ml/L of water). Group E served as the infected/non-medicated control group. At two weeks of age, all groups were infected with 50,000 sporulated oocysts of Eimeria tenella. The anticoccidial potential was evaluated based on lesion score, oocyst score, fecal score, feed conversion ratio, and mortality (%). Furthermore, the effect of ABE on hematological parameters and serum chemistry was also evaluated by following standard procedures. The anticoccidial effects were compared with the standard drug Baycox® (p>0.05). Results of the study showed the anticoccidial activity of ABE in terms of lesion diminishing, oocyst and fecal scores, better feed conversion ratios, and mortality reduction (%). The ABE also improved hematological parameters and stabilized the serum enzymes (ALT, LDH, Creatinine) of infected chicks (p>0.05).(AU)

Influence of Moringa oleifera leaf meal used as phytogenic feed additive on the serum metabolites and egg bioactive compounds in commercial layers

Phytogenic feed additives have been increasingly used in the last decade, and several plants and their metabolites have been investigated for the said purpose. In this context, present study aimed at evaluating the effects of Moringa oleifera as feed additive on layer performance, and egg bioactive compound levels and nutrient profile. HyLine W36 layers (n=200), 50 weeks of age, were randomly distributed in four treatments with five replicates of ten birds each. Four isocaloric (2725 kcal/kg) and isonitrogenous (CP 16%) diets were formulated and supplemented with 0, 0.5, 1.0, or 1.5% (w/w) of dried Moringa oleifera leaf powder (MLM). The results showed positive effects of MLM on egg production, egg mass, and feed conversion ratio, but negative effects on egg quality (p≤0.05). The contents of bioactive compounds, like β-carotene, quercetin, and selenium, in the diet and in the egg yolk were significantly (p≤0.05) higher in the group fed1.5% MLM, with values of 8.90, 48.88, and 0.54 mg/kg feed and 4906, 241 and 56.82 µg/100g yolk, respectively. Creatinine and glucose serum levels and cholesterol levels (serum and eggs) linearly increased as a function of increasing MLM dietary levels (p≤0.05). Antibody titers against Newcastle Disease significantly improved (p≤0.05) in the group fed the diet supplemented with 1.5% MLM. It was concluded that Moringa oleifera used as phytogenic feed additive enriches eggs with bioactive and functional compounds, and improves the production performance and the health status of layers.(AU)
