an in vivo experiment was conducted to determine the effect of dietary betaine supplementation (betafin®) as a replacement for methionine on broiler performance and carcass characteristics. in a completely randomized design (crd) with five treatments of betaine levels (at 0, 25, 50, 75, and 100% in replacement for methionine) and five replicates of 10 birds/replicate, two hundred fifty-day-...

in order to study the effect of dietary physical form on the fattening performance of holstein male calves, an experiment was conducted in animal science research institute of iran in 2011. the experimental diets were formulated and prepared with two physical forms including total mixed ration (tmr) and densified complete feed block (dcfb). in a completely randomized block design, with two trea...

The toxicity of maize containing known doses of fumonisin B1 (FB1) was investigated in mallard ducks during force-feeding. Seventy-five ducks at 12 wk of age were randomly divided into 3 groups of 25, and received control maize, naturally contaminated maize containing 20 mg/kg of FB1, or a mixture of control and contaminated maize (50/50, vol/vol). Force-feeding was performed during 12 d that c...

The poultry market has changed due to a higher consumer interest on products with differentiated organoleptic characteristics, making of free-range broiler production a promising activity. This experiment was conducted to determine the digestible lysine requirements of Redbro Cou Nu male and female chickens during the starter phase (one to 21 days of age). Six hundred and thirty Redbro Cou Nu b...

Forty-five, day-old broiler chicks with an initial average weight of 30.25±2.40 g were divided into three groups of fifteen animals each. The first group was placed on soybean-based (control) diet; the second group on raw (unfermented) T. catappa seed meal-based diet; and the third on A. niger-fermented T. catappa seed meal-based diet, for seven (7) weeks. Feed intake, feed conversion ratio, av...

Background: Liver fatty acid-binding protein (L-FABP) is the main cytosolic binding site for long chain fatty acids in hepatocytes. FABPs enhance the uptake of fatty acids into the cell by increasing their concentration due to decreasing concentration of unbound fatty acids inside the cell. Objectives: The aim of this study was to evaluate the effects of dietary unsaturated to saturated fatty a...

Commercial aquaculture is growing worldwide except in Africa where production is still low. With fisheries reaching a stagnating phase, the world and more so Africa will have to look to aquaculture in the future to provide fish products that will likely be needed. In view of this, a study on water quality management was done which specifically looked at the effects of dissolved oxygen saturatio...

Availability of nucleotides may limit performance in fast growing animals. An experiment was conducted to determine the efficacy of a nucleotide preparation (Nucleoforce Poultry) in broiler chickens. Nine hundred and sixty day-old broiler chickens were allocated into 24 pens, and assigned one of 3 treatments: 0, 500 and 1000 mg of the nucleotide preparation/kg feed. Feeds were based on wheat, b...
