The cultivation mode plays a vital role in algal growth and composition. This paper assessed the ability of twelve algae–microbial consortia (ACs) originally selected from organic wastes when nano-filtered pig slurry wastewater (NFP) cheese whey (CW) were used as substrates mixotrophic comparison with photoautotrophic mode. Nutrient uptake ability, biochemical composition, fatty acids, amino ac...

Objective: The effect of xylanase and fructooligosaccharides on broiler chickens body weight, feed conversion (kg feed/kg weight), caecal volatile fatty acids (VFA) concentration and glycolytic enzymes activity was investigated. Methods: Six hundred birds were divided into three groups and for 35 days were fed basal diet (control) and diets contained 0.1% xylanase and 2% fructooligosaccharides ...

Adding supplements to hen feed can increase egg nutritional value. Astaxanthin, tocotrienols, and tocopherols are potent antioxidants that provide health benefits to humans. We hypothesized that the addition of these nutrients to hen feed would result in an increased nutrient content in egg yolk with minimum changes in functional properties. Laying hens (Hy-Line W-36 breed) were fed four diets ...

Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...

Increasing competition in the livestock industry has forced producers to cut costs by adopting new technologies aimed at increasing production efficiency. One particularly promising technology is feeding enzymes as supplements for animal diets. Supplementation of diets for non-ruminants (e.g., swine and poultry) with fibrolytic enzymes, such as cellulases, xylanases and beta-glucanases, increas...

A study was conducted to investigate the effects of feeding inorganic or organic Zn and Cu on the performance and tissue mineral content of chicks. A corn-soybean meal diet without Cu and Zn supplementation, containing 31 mg of Zn/kg of diet and 6.6 mg of Cu/kg of diet, was used as a basal diet. Organic Zn (a chelated Zn proteinate) and organic Cu (a chelated Cu proteinate) were used as organic...

The effects of basil and/or chamomile seed supplementation on the growth of Hubbard broiler chicks were evaluated. The antioxidant effects of these supplements were also assessed. 120 1-day-old broiler chicks were randomly divided into four equal groups. The control group (group 1) was fed a basal diet (BD) without supplementation. Groups 2, 3, and 4 were fed the BD supplemented with 10g basil,...

The study was conducted to evaluate the effects of feeding varying levels of Ficus sycomorus leaf forages as protein supplements to a basal diet of urea treated maize stover. Four Yankasa goats averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. The basal diet (urea treated maize stover) was supplemented with 0 (T1), 50 (T2), 100...

campylobacter is known to be one of the most common causes of human intestinal disorders. since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. the effects of probiotic (primalac®), medicinal plant (sangrovit®) and organic acid (selko-ph®) as broiler feed additives on ...
