The aim of this study was to investigate the effect of wet feeding on feed conversion efficiency in laying hens during summer season. The study was carried out on 192 pullets of eight weeks age (distributed to four groups). The feed offered to chicks consisted of starter diet up to 8 weeks of age and grower diet up to 20 weeks of age. From 20 weeks onwards, birds were provided with layer diet u...

The feed resource for animals is a major cost determinant for profitability in livestock production enterprises, and thus any effort at improving the efficiency of feed use will help to reduce feed cost. Feed conversion ratio, expressed as feed inputs per unit output, is a traditional measure of efficiency that has significant phenotypic and genetic correlations with feed intake and growth trai...

a random block experiment 4×4 with sixteen diets containing four level of protein (35, 40, 45 and 50%) at four carbohydrate to lipid level (1.7, 1.4, .1 and 0.8 ) were designed to research about the ability of utilization of different levels of protein and carbohydrate to lipid ratios diet for juvenile huso huso ( 5.4 ± 0.2, mean sd )in fourteen weeks. fish fed 2-3% of body weight at each day. ...

The effect of fermented wheat germ extract (FWGE, Immunovet-HBM) was studied in chickens challenged with Mycoplasma gallisepticum. Ninety M. gallisepticum- and M. synoviae-free 3-wk-old chickens were exposed to aerosol infection of M. gallisepticum. One group (30 birds) was treated with FWGE, a second group with tiamulin, and a third group was untreated. The fourth group was exposed to PBS aero...

four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (csos) as a substitute for refined soybean oil (rso) in broiler diet. the experiment was carried out following completely randomized design. the chicks were randomly distributed in three treatment gr...

the freshwater angel fish (pterophyllum scalare schultze, 1823) is south american cichlid become very popular among aquarists. there is little information on their culture and aquarium husbandry. in this study growth performance and survival rate of angelfish subjected to different feeding frequencies were evaluated. four groups of angel fish juveniles (0.87 ± 0.01 g; 3.98 ± 0.08 mm) were fed e...

The field-effect enzymatic detection (FEED) technique was used to control the kinetics of the enzymatic conversion of glucose to gluconolactone. The glucose-gluconolactone conversion occurring at an enzyme-immobilized electrode, a well-studied process, was confirmed using mass spectrometry. Electrochemical studies showed that the glucose oxidation current depends on the gating voltage VG and th...
