Genetic improvement in growth rate and feed conversion ratio is known to be an efficient way to increase production and increase efficiency in fish farming.

Today, fish farming faces an increasing demand in fish products, but also various environmental challenges. FCR was significantly better (pdiet may improve FCR without any adverse effect on blood biochemical attributes and immune competence traits.Įnvironmental impacts of genetic improvement of growth rate and feed conversion ratio in fish farming under rearing density and nitrogen output limitationsīesson, M. There was no significant difference among the different groups in the average weekly weight gain during the entire experiment. The birds of the control group (T1) were fed a basal diet (CP - 19.71% and ME - 2789.79 Kcal/kg), while the other group (T2) and choice- feeding group (T3) were fed 5% of basal diet replaced by dry Azolla powder on DM basis and ad libitumAzolla along with basal diet, respectively. A total of 72, 8-week-old grower turkey poults of black variety were randomly distributed into three dietary treatments having three replicates each with eight birds. Hence, a study was carried out to evaluate the effect of dried Azolla pinnata vis-a-vis raw Azolla as choice feeding on the growth, feed conversion ratio (FCR), blood biochemical attributes, and immune competence traits of growing turkeys under intensive system. If turkeys effectively use unconventional feedstuffs like Azolla without reducing the performance, it will increase the profitability of turkey business. In the recent past,few studies have been carried out in chicken to assess the effect of Azolla meal and raw Azolla feeding on the performance of chicken. Shukla, Mayank Bhattacharyya, Amitav Shukla, Pankaj Kumar Roy, Debashis Yadav, Brijesh Sirohi, Rajneesh The optimum doses of phytase enzyme on RGR, FCR, PER, ADCP and ADCF of gift tilapia saline fish ranged from 1060 to 1100 FTU kg-1 feed.Įffect of Azolla feeding on the growth, feed conversion ratio, blood biochemical attributes and immune competence traits of growing turkeys. The results show that the addition of phytase enzyme was significantly (P0.05) affected on Survival Rate (SR) of gift tilapia saline fish. The treatments were by adding phytase enzyme in artificial feed with the different level of doses those were A (0 FTU kg1 feed), B (500 FTU kg1 feed), C (1000 FTU kg1 feed) and D (1500 FTU kg1 feed). Experimental method used in this study was completely randomized design with 4 treatments and 3 repetitions. niloticus) with an average weight of 0,62 Â± 0,008 g/fish and the stocking density of 1 fish1 L. The fish samples in this study used gift tilapia saline fish (O.

The purpose of this study was to determine the effect of adding the phytase enzyme in the artificial feed on digestibility of feed, feed conversion ratio and growth of gift tilapia saline fish (Oreochromis niloticus) nursery stadia I.

Rachmawati, Diana Samidjan, Istiyanto Elfitasari, Tita The variables selected in the models explained approximately 44 and 20% of the total variance in the DFI and FCR, respectively, demonstrating that this resource is a good tool for interpreting the factors related to the parameters evaluated.Įffect of The Phytase Enzyme Addition in The Artificial Feed on Digestibility of Feed, Feed Conversion Ratio and Growth of Gift Tilapia Saline Fish (Oreochromis niloticus) Nursery Stadia I It was observed that the FCR was influenced by the barnâ€™s position relative to the sun (P = 0.0001, the use of humidifiers/misting (P = 0.03, the presence of composters (P = 0.006, trees on the sides of barns (P < 0.045, the initial body weight of the pigs (P < 0.0001 and duration of the grow-finishing phase (P < 0.0001. The DFI was influenced by the barn's position relative to the sun (P = 0.048, initial body weight (P < 0.0001 and final body weight (P < 0.0001.

Forty production factors were considered that related to management, sanitation, installations and equipment, nutrition, genetics and environment on the farms. Sixty-five GF farms were evaluated between 20, linked to a cooperative system located in the western Parana State, Brazil, representing 463 batches, with a mean of 642.79 Â± 363.29 animals per batch, equalling approximately 300,000 animals. Influence of production factors on feed intake and feed conversion ratio of grow-finishing pigsĭirectory of Open Access Journals (Sweden)įull Text Available The aim of this study was to identify and quantify, through mathematical models, the production factors of grow-finishing (GF phases that influence the daily feed intake (DFI and feed conversion ratio (FCR in pigs.
