This study was conducted to evaluate the effects of 3 rearing systems ( FL : flooring litter rearing, MC multilayer cage PN plastic net rearing) with or without supplemental narasin on growth performance, gastrointestine development and health broilers. A total 2,400 one-day-old Ross 308 mixed-sex broilers (1:1 ratio males females) were used in a completely randomized design utilizing × 2 facto...

Female mosquitoes use abiotic and biotic factors, such as the presence of heavy metals or parasites, to determine the acceptability of oviposition sites. Some biotic factors can originate from mosquito larvae. When mosquito larvae are starved or infected with trematode metacercaria, they render associated water unacceptable to ovipositioning females. Internal symbiotes are common in wild mosqui...

The aim of the research was to evaluate the influence of sex, breeding group, litter size and age of lambs when placed in lambing pens for their growth rate during rearing. The average daily gain of lambs was evaluated based on their weighing data each week after their placement into lambing pens. Lambs of Improved Valachian, Tsigai and Lacaune breed (n=26) had been gradually integrated to the ...

grey mullet (mugil cephalus) is an important food fish species in the, mugilidae which is able to adapt in a wide range of salinities and temperatures and is suitable for introduction of the species to freshwater, brackish, and brine waters for aquaculture. this study was implemented to determine appropriate normative of stocking density and initial weight ofmugil cephalus and also evaluate eff...

Three-hour milk production measurements determined by machine milking at 3-d intervals throughout a 63-d lactation period were used to describe lactation curves for crossbred ewes lambing at 1 and 2 yr of age and rearing single and twin lambs. Age of ewe, type of rearing, and day of lactation affected (P < 0.05) milk production. Over the 63-d lactation, average daily milk production was 2.56 an...

Effects of natural and artificial diets under two rearing methods (group individual) on larval pupal development survivability Spodoptera litura (Fab.) were studied. The survival rate larvae pupae was significantly affected by (P = 0.05), which higher diet when reared individually. Results this study documented the growth index from diet. indices 5.24 1.65 individual group rearing, respectively...
