The researches has been carried out on a number of 250 broiler turkey juveniles, the Big 6 hybrid, distributed in 5 groups of 50 juveniles/group over a period of 56 days. After 56 days, the experiment was carried out on 3 groups over a period of 84 days, recording the production indices; at the end of the experimental period (at the age of 140 days) meat quality and chemical composition were determined. In the first 2 stages, the fodders were supplemented with Allzyme SSF complex 0.02%, Bio-Mos 0.1%, organic Selenium 0.03% and Bio-Mos 0.1% and Allzyme SSF 0.02%. The turkeys were weighted at the beginning of the experimental period (at the age of one day) and then weekly, recording the evolution of body mass, the daily average weight gain, the daily average consumption and the feed conversion ratio (FCR). The use of Sel-Plex, Bio-Mos + Allzyme SSF, Allzyme SSF and Bio-Mos for 56 days, determined the increase of the body weight, the increase of daily average weight gain, and a decrease FCR value. In the 3rd, 4th and 5th stage, the best results regarding growth and consumption indices were recorded also in experimental groups. At the end of the trial, meat quality and chemical composition of meat were determined. The administration of the Allzyme SSF enzyme complex and the organic mineral Sel-plex led to the improvement of the meat quality due to an increase in meat protein content and a reduction of meat fat content.

Nowdays, worldwide in sericulture domain, researches are aimed to find new efficient alternatives for the feeding of mulberry silk worm through the use of some fodder additives which allow the improvement of bioproductive parameters and silk line quality. The present work represents a review of the use of such substances (mineral and vitamin additives) and of the experiments carried out to point out their effects on silkworms (Bombyx mori L.). Research conducted worldwide revealed the fact that the use of mineral and vitamin additives in silkworm Bombyx mori L., improve the growth rate of larvae, protein and mineral content of haemolymph, the protein content, DNA and RNA content of the sericigen glands, and the quality parameters of cocoon and silk line. Researches showed that the use of these additives doesn’t affect the quality of the silk.

The trial had been carried out during 5 May–30 September 2009, (23 weeks) at the trout farm ICAS Gilau, Cluj County. Two groups were implied: a Control group and one experimental group (Bio-Mos0.2%+SelPlex0.03%+NuPro2%) each consisting of 250 rainbow trout juveniles. The experimental group received 0.2 % Bio-Mos+0.03% SelPlex+2%NuPro. At the end fish reached an average weight of 253.20 g/specimen for experimental group and 241.10 g/specimen for the Control group. The growth rate incresed by 5.23 % at the experimental group comparative with the Control group. The highest value of specific growth rate was recorded at group E, 1.51 g/day, with 5.59 % higher than the specific growth rate of the Controls. The addition of combined fodder additives in group E feed led to an abatement of the feed conversion rate (1.39:1) by 2.12 % smaller comparative with the Control group (1.42:1). The analysis of indices regarding the fish health and survival rate, showed the positive effects of the combined additives. At intestinal level it was noticed an increasement of villi lenght at group E with 10.72 % higher comparative with the Control group. A significant improvement of selenium content of rainbow trout meat was also noticed.

The aim of this research was to evaluate the use of additives in fodders for common carp (Cyprinus carpio L.). The experiment was carried out for a period of 257 at the fish farm from Mărtineşti in the county Cluj. The fish ware divided in 6 groups, LM-control group and 5 experimental groups; the fodder for the experimental groups was supplemented with Allzyme SSF (L1E), Bio-Mos (L2E), Allzyme SSF and Bio-Mos (L3E), Allzyme SSF and Sel-Plex (L4E) and Allzime SSF, Bio-Mos and Sel-Plex (L5E). Each batch contained 100 fish divided as it fallows: 50 common carp from Lausitz var. and 50 common carp from Galitian var. The average weight for both varieties of common carp was 1.5 g/ specimen. The groups were distributed in 6 cages with 150 mp. The best results regarding growing indices for Galitian var. ware obtained by L4E group with medium weight (MW) of 791.73±35.05g and the survival rate (SR) of 94%, compared with LM group (MW=743.37±39.20g and SR= 88%). In the case of Lausitz var. the best MW was obtained by L1E with 908.36±34.33g compared with LM (MW= 794.66±26.61g) and the best survival rate was obtained by L4E and L5E with SR=94% compared with LM (SR= 76%). The results reveal that the supplementation of fodder for both varieties of common carp (Lausitz and Galitian var.) carp with used additives determined a better growing rate and a better survival rate.

The experiment aimed to determine the bioproductive effects of the administration of phytoadditives in rainbow trout feeds. The additives were represented by garlic, ginger, oregano and Echinacea that where added into rainbow trout feed in proportions of 2% garlic (L1E), 1% ginger (L2E), 1% oregano (L3E) and 0.5% Echinacea (L4E). The experimental period was 116 days. The greatest weight gain was recorded in the L3E group and the lowest in the L4E group. The highest specific growth rate was recorded in the L4E group. The lowest feed conversion ratio was recorded in the L3E group and the highest in the control group Analyzing the meat chemical composition, the highest increase in dry matter was recorded in L1E group compared with the control group; the biggest increase in the Gross Protein value was recorded in L4E group, the L3E group showing a decrease compared with the control group. Regarding the Gross Fat content, the highest value was recorded in the L1E compared to the control group while the L3E group showed a decrease of GF content, compared with the control group. The results obtained confirm the beneficial effects of these phytoadditives on the growth and consumption indices in rainbow trout.

We used Helix pomatia and Helix aspersa species and measure their growth as the snails were approaching the hibernation season. Helix pomatia 2yo shown a decrease in weight while being raised in enclosed parcels of 4sqm the younger Helix pomatia 1yo as well as Helix aspersa Muller demonstrated the ability to adapt relatively fast to the same conditions. We established 5 experimental lots in a Helix pomatia farm, GPS coordinates N46.606040 E23.599950. Control lot contained Taraxacum officinales, Sonchus oleraceus, Equisetum arvense and Atriplex hortensis, wild flora found within the farm. The other lots contained the same plants as the control lot plus different combinations of imported plants from other areals. The H. pomatia 2yo weight decreased in the control lot by a mean of -3.86% while H. aspersa 1yo marked an increase of +16.89% in the same lot during the same period. The lot containing lupinus polyphyllus delivered snails with weight gain of +24.66% for H. pomatia 2yo and an increase of only +1.98% for H. aspersa 1yo. As a contrast, H. pomatia 2yo gained only +7.72% while H. aspersa 1yo gained +28.89%, in the lot containing Lavanda officinalis, Foeniculum vulgare and Hyssopus officinalis among the other plants.

The trial was carried out for 35 weeks at the trout farm ICAS Gilau, Cluj County. Three groups were implied: a Control group and two experimental groups (Bio-Mos 0.2 % and SelPlex 0.03 %) each consisting of 250 brook trout juveniles. The experimental groups received 0.2 % Bio-Mos and 0.03% SelPlex. At the end fish reached an average weight of 238.55 g/specimen for experimental group 1 and 212.2 g/specimen for the second experimental group comparatively to the Control group (204.65 g/specimen). The analysis of indices regarding the quantification of the health status, survival and losses, shows the benefical biological effects of the additives that had been incorporated in the basal diet of brook trout. The improvement of gluthation-peroxidase blood level in group 3 (5.63 UGPx/mlPCV) comparative with that registered at the Control group (4.34 UGPx/mlPCV) is another evidence of the biological benefical effects of Selenium. Also there have been a significant improvement of selenium content of brook trout meat, with 287.15 % higher than the Control group (238.99 µg/kg comparative with 61.73 µg/kg) as a response to brook trout diet supplementation with organic selenium. The addition of Bio-Mos and SelPlex in brook trout feed did not have a major impact on the chemical composition of brook trout meat, the differences recorded being insignificant.

The researches had been made on a number of 150 broiler turkey juveniles, the Big 6 hybrid, assigned in 3 batches of 50 juveniles/batch for a period of 56 days (the growth stage). In the feed of batch 2(E) was added Allzyme SSF complex 0.02% and in the feed of bach 3(E) was added the organic Selenium (Sel-Plex) 0.03 %. The turkey broilers of the three batches were weighted at the beginning (at the age of one day) and each week following: the evolution of body mass, the daily average body gain, the daily average consumption and the specific consumption. The use of Sel-Plex in the feed of batch 3(E) and the use of Allzyme SSF in the feed of batch 2 determined the increase of the body weight at the end of experiment with 15.35 % at batch L3(E) and 8.00 % at batch L3(E), the increase of daily average body gain with 15.52 % respective 18,08% and the allowance of the specific consumption with 19.07 % at batch L3(E) and 14.88 % at batch L2(E) with low energy reformulated food comparative with batch L1(M) and batch L3(E). The results obtained confirm the positive influence of Sel-Plex and Allzyme SSF enzymatic complex on the main production and consumption parameters of broiler turkey juveniles.

This study is focused on the impact of organic selenium (Se) (Sel-Plex) on the growth performance, consumption and quality of meat in the case of carp (Cyprinus carpio), Galitian variety. The experiment was conducted over two years and had the following structure: (1) growth stage juveniles (159 days, year 2008); the period of hibernation; and (2) the status of fish for consumption (200 days, year 2009). Fish growth was conducted at Mărtineşti fish farm, Romania. The total number of specimens was 200, organized in two equal groups: experimental group and control group. Average weight of individuals at the beginning of the experiment was 1.5 g/individual. Growth conditions were identical for the two groups, except food. The experimental group received 0.03 mg organic Se/kg food. At the end of the experiment the individual average weight of the experimental group was 1191±014.21g/individual, with a food conversion rate of 1.79:1:1 kg foodd/kg body weight; compared to the control group with a mean weight of 908.67±17.78g/individual and a food conversion rate of 1.88:1 kg foodd/kg body weight. Regarding these indices significant differences resulted between two groups when analyzing experiment results; while, regarding meat quality in terms of protein content, dry matter, water and fat there were no significant differences between the two groups. Analysis was done using ANOVA program.

This research aimed to evaluate the influence of Zinc, administered as food supplement for silkworm (Bombyx mori L.) on the larvae weight, the weight of the serigene gland, cocoon weight, cocoon shell. The research has been carried out on 5 groups of silkworms one control group (Gr.1) and 4 experimental groups (4 groups receiving zinc), consisting of 50 larvae/group. Zinc was administered in doses of 17, 34, 68 and 136 mg kg-1 larvae - Gr.2-Gr.5. The use of Zinc determined a very significant increase of the larvae weight, to group Gr.5 followed by groups Gr.4, Gr.3 and Gr.2 compared to the control group. The use of Zinc positively influenced the mass of the serigene glands, the cocoon weight, cocoon shell. The Zn content of the pupae from the experimental groups was higher compared to the one recorded in the control group.

The present trial aimed to determine the effects of some phytoadditive combinations (garlic + ginger – group 1E and oregano + Echinacea – group 2E) on the growth and consumption indices and resistance to Aeromonas hydrophila in common carp (Cyprinus carpio) juveniles reared in a recirculating system. Dietary administration of phytoadditives led to a higher body weight gain in the experimental groups compared to the control, also leading to a higher specific growth rate and to a lower FCR value. Also the survival rate was improved by the dietary treatment with the phytoadditive combination, the highest survival rate being recorded in the 1E group. A test infection was carried out after 13 weeks of feeding, in order to determine the effect of the phytoadditive combinations on disease resistance. So, the survival rate was improved in all the experimental groups compared to the control. Selenium content of meat was also determined, the highest values being recorded in group 1E, both the experimental groups presenting higher values than the control group. Dietary treatment using phytoadditive combinations had a positive influence on the growth and consumption indices, also improving the survival rate and disease resistance

The purpose of research was to determine the effects of Allzyme SSF administration after introducing of alfalfa meal in feeds, over performances of common carp (Cyprinus carpio L.) and grass carp (Ctenopharyngodon idella V.) juveniles. The experiments where carried out on 75 common carp (Cyprinus carpio L.) – mean initial body weight 47.5g/fish and 75 grass carp (Ctenopharyngodon idella V.) – mean initial body weight 24g/fish; the fishes were randomly distributed in three groups: control group M - feed with base diet, experimental group 1E - 70% base diet and 30% alfalfa meal and experimental group 2E - 70% base diet and 30% alfalfa meal and 0.02% Allzyme SSF. The digestibility coefficient of Crude Protein, Crude Fat and Crude Fiber were higher for common carp and grass carp juveniles after supplementation with Allzyme SSF compared to the other groups. The production and consumption indices were improved for groups 2E from both common carp and grass carp juveniles, compared with 1E group and to the control group. The SGR and FCR were improved in group 2E for common carp and grass compared to the other groups. The results indicate the positive effects of Allzyme SSF on enhancing the ADC of vegetal raw materials.

The goal of this research was to analyze the effect of organic Selenium (SelPlex) on the reproductive function in 3 summer old males common carp (Cyprinus carpio), Lausitz variety. The researches were carried out on two groups on a total 12 males carp in 3 summers old (6 in each group). Experimental period was 39 day and organic Selenium (SelPlex) at a dose of 0.03 mg/kg feed was added in the feed for the experimental group. The use of SelPlex significantly influenced the concentration of spermatozoa of the three summers carp. Analyzing the results obtained shows that the addition of organic selenium in the nutrition of carp breeders caused a slight increase in protein, and fat decreased slightly from sperm, the differences between groups were non-significant (p>0.05%). The slight increase in the amount of protein in milt is due to the positive effect of organic selenium over glutathione peroxidase activity of sperm cores (SN-GSH-Px), which is an integral part of sperm chromatin with the possibility of amino-acid uptake. Researches regarding viability, meristically and somatic measurements of breeders were carried out and significant differences were recorded in the experimental group compared to the control.

Phytoadditives have been used for millennia in traditional human medicine but only recent in animals to improve the growth performances and to reduce disease outbreaks. The goal of the present experiment has been to determine the effect of phytoadditive combinations on growth performances and meat quality in rainbow trout (Oncorhychus mykiss). The phytoaditive combinations were represented by garlic (2%) + ginger (1%) – group 1E and oregano (1%) and Echinacea (0.5%) – group 2E. the dietary treatment with phytoadditive combinations led to a better body weight gain in all the experimental groups compared to the control. Also the specific growth rate and the FCR values were improved in the experimental groups, the best values being recorded in group 1E. the experimental groups also had a higher survival rate, the highest value being recorded in group 1E. meat quality was not significantly influenced by dietary treatment of phytoadditive combinations. The meat Selenium content significantly varied among all experimental groups, the highest value being recorded in group 1E and the lowest in the control group. Dietary treatment with phytoadditive combination had a positive influence on growth and consumption indices with no significant changes in meat quality but significantly influencing the meat Selenium content.
