This research aimed to evaluate the effect of different doses of black cumin (Nigella sativa L.) seed (BCS) on growth performance, blood parameters, liver oxidant/anti-oxidant levels and fatty liver syndrome in quails. Four hundred and thirty-two unsexed (male and female) three-day-old Japanese quail (Coturnix coturnix japonica) chicks were divided into four treatment groups (108 chicks per group) with six replicates (18 chicks per replicate). Control and experimental groups were fed for 35 days with basal quail feed including 0.00, 0.50, 1.00 and 2.00% BCS supplement, respectively. At the end, a total of 96 quails, 24 from each group (12 females and 12 males) were slaughtered. The BCS-addition did not affect the growth performance in the experimental groups compared to the control group. Addition of BCS to the diet significantly decreased serum aspartate aminotransferase, lactate dehydrogenase and urea amounts compared to the controls. Whereas, cholesterol decreased significantly with the addition of only 1.00% and low-density lipoprotein with the addition of 0.50 and 1.00% BCS compared to the controls. Liver glutathione levels significantly elevated in 0.50 and 1.00% BCS fed groups; while, glutathione peroxidase levels significantly decreased in 1.00 and 2.00% BCS fed groups. Adding 1.00 and 2.00% BCS to the feed reduced fatty liver incidence in male quails. It is concluded that adding 0.50 and 1.00% BCS positively affects the blood and liver parameters; therefore, BCS may be suggested as an anti-oxidant source to help protect hepatocytes against tissue damage as it has a significant effect on maintaining oxidant and anti-oxidant balance.

Abstract
This study was conducted to determine the effects of mannan oligosaccharide (MOS) on growth, some immune responses and gut lactic acid bacteria of common carp. Four experimental diets containing 0%, 0.05%, 0.10% and 0.20% MOS were prepared. Each diet was randomly allocated to triplicate groups of fish ...

This study was conducted to determine the effects of mannan oligosaccharide (MOS) on growth, some immune responses and gut lactic acid bacteria of common carp. Four experimental diets containing 0%, 0.05%, 0.10% and 0.20% MOS were prepared. Each diet was randomly allocated to triplicate groups of fish with initial average weight of approximately 14 g. After eight weeks, survival rate was high in all treatments with no significant difference (p > 0.05). Growth performance including final weight, weight gain (WG) and specific growth rate (SGR) did not differ among the treatments. Feed conversion ratio (FCR) was better when the fish were fed 0.05 to 0.20% MOS diets. The alternative complement activity, lysozyme activity and serum total Ig were found to be significantly (p < 0.05) greater in fish fed 0.20% MOS diets. Although the total intestinal bacterial counts were not affected by dietary treatment (p > 0.05), the lactic acid bacteria levels were significantly elevated in fish fed MOS diets (p < 0.05). These results indicated that oral administration of MOS at 0.20% elevated the immune response, improved FCR and modulated intestinal microbiota of common carp.

It is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. In this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. Twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth worm (LEW), dried Tubifex (DT), dried Gammarus (DG) and prepared granulated feed (PGF), twice a day for 90 days. Reproductive parameters were measured between days 60 and 90. The significant increase in the gonadosomatic index (GSI), fecundity and hatchability brought about by the LEW were demonstrated by the higher number of spawned eggs and hatched larvae. The best growth observed significantly in PGF, and length of larvae was enhanced in this group, consequently. The numbers of dead and deformed fry were lower in the fish fed with PGF and LEW, but there was no significant difference among experimental groups. This study showed that breeders benefit from inclusion of prepared granulated feed and living earth worm during their growth and reproductive stages, and simultaneous using of them for achieving better results is suggested.

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 either four meals per day (F1), two meals per day (F2), one meal per day (F3) and every other day (F4) for 90 days. Final live weight and specific growth rate (SGR) values of group F1 and F2 were significantly higher than those of the other groups (P < 0.05). There was no significant difference (P > 0.05) in survival rate among the treatments. The best feed conversion ration (FCR) was obtained from four daily feeding (F1) (P < 0.05). Condition factor (CF) did not show a significant difference (P > 0.05) among experimental groups. In conclusion, the best results in growth performance were obtained by feeding four meals per day (F1) and two meals per day (F2), so they were recommended for angel fish feeding.
