Results of previous research have demonstrated that shrimp production is similar at protein levels ranging from 20 to 40%, when shrimp are stocked at densities ranging from 5 to 11/m2 (TeichertCoddington and Rodriguez, 1995a). These results indicated that shrimp stocked at semi-intensive levels did not require diets containing high levels of protein. However, some think that food conversion can...

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...

Two experiments were conducted to identify factors influencing feed conversion in broilers. The first experiment was conducted to develop a test for body temperature (BT) under mild handling stress. In the first experiment, BT was recorded periodically with birds briefly restrained after they had been removed from feed with either continuous lighting or 16L:8D. Body temperature was affected by ...

The effect of energy and protein dilution in the starter period (8 to 14 days) of age, on performance and carcass characteristics of 360 Arian male chicks was studied in a completely randomised design. This experiment consisted of 6 treatments, 4 replicates, with 15 chicks per replicate. In order to dilute the diets six levels (0, 4, 8, 12, 16, and 20) percent of ground wood charcoal was used. ...

The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...

Total sixty four straight run broiler chicks of two daysold were fed a control diet and diet supplemented with Fungi inhibitor (FI): Gentian violet (GV), Copper sulphate (CS), GV+CSto evaluate the effect of dietary FI on the performance characteristics of broiler. The levels of GV, CS and GV+CS were 0.05%, 0.06% and 0.025%+0.06%, respectively. Dietary FI did not alter the growth rate, feed inta...

Feed costs are a major cost component of pig production and the optimal use of feed for production is therefore of high importance in an economic and sustainable pig industry. The amount of food eaten by the growing pig is used for maintenance and growth which includes lean meat as well as fat growth. The aim in pig production is to produce lean meat most efficiently which is achieved by optimi...

an experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (se) sources on broiler male birds (ross 308). uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental se, negative control), 0.25 ppm of inorganic se, 0.5 ppm of inorganic se, 0.25 ppm of inorganic se + 0.25 ppm of organic ...
