The study was conducted to investigate the effects of a multi-enzyme complex (Rovabio Excel) containing carbohydrolase activities on the performance of broiler chickens. Test diets were formulated to include 12% corn distillers dried grain with solubles (DDGS). In total, 1200 Cobb 500 broiler males were randomly assigned to 8 replicate pens of 50 birds per treatment and grown to 45 d of age usi...

An appropriate stocking density is beneficial to run an efficient business and improve animal welfare. In most traditional livestock this defined as the number of animals per area. However, larvae mealworm (Tenebrio molitor), one important commercial insects, live both on top inside their feed. study we assessed if different areal densities (2D, range 0.6-10.4 larvae/cm 2 ) resulted in a growth...

The current study was undertaken to estimate variance components for phytate P bioavailability (PBA) and the genetic correlations among PBA with growth and feed utilization (or intake) traits in an unselected random mating chicken population. Pedigreed data from 901 Athens-Canadian randombred chickens hatched from 26 sires, 71 dams, and 105 grandparents were used for estimation of genetic param...

This paper reports on the statistical analysis of the 1995 survey of 451 shrimp farms in Thailand. The aim was to identify relationships which may indicate key issues for research into sustainability. Rigorous cleaning up of the data was carried out to eliminate cases where the data could not be validated or where a respondent consistently omitted data. In the subsequent analysis, nine key outc...

This study was performed to investigate the effects of feeding rates on growth performance, feed conversion and body composition of juvenile snow trout (Schizothorax zarudnyi). For this purpose, fish with an initial body weight of 2.17±0.1 g were fed a commercial diet (40% protein, 3.8 Kcal g-1 diet) at five ration sizes of 2%, 4%, 6%, 8% and 10% of their body weight per day, for 60 days. The f...

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...

Feed intake and feed efficiency are economically important traits in beef cattle because feed is the greatest variable cost in production. Feed efficiency can be measured as feed conversion ratio (FCR, intake per unit gain) or residual feed intake (RFI, measured as DMI corrected for BW and growth rate, and sometimes a measure of body composition, usually carcass fatness, RFI(bf)). The goal of t...

This study was aimed at investigating the influence of different proportion water to dry meal, give a moist feed form in feeding Muscovy duck (Cairina moschata) and assess these forms on growth performance carcass characteristics. A completely randomized design fifty-four one two weeks old ducklings weighing 64 67 g were randomly distributed into 3 treatments with three replicates each, used fo...

background: coccidiosis is recognized as the parasitic disease that has the greatest economic impact on poultry production. modern poultry production is largely dependent upon anticoccidials. objectives: the aim of the present study was to determine and compare the efficacy of two chemical anticoccidials (clopidol and diclazuril) on oocyst shedding and their probable effects on growth performan...
