Abstract:
The article describes that domestic feed products cannot always compete with high quality products of foreign firms. However, the use of imported feed leads to a significant increase in their value and, as a consequence, to an increase in the cost price of the final product. It is established that for the normal development and realization of productivity, turkeys should receive quality and balanced for all indicators of compound feed. Therefore, the task was to develop recipes for turkeys using high quality domestic raw materials. The necessity to determine the complete components characteristics of compound feeds for the finished products production, which meets the requirements of regulatory documents and the consumer, has been proved. There are many indicators and factors that are not taken into account when calculating recipes, but significantly affect the compound feed quality. We have developed compound feed recipes for heavy type turkeys aged 1…4 weeks, 5…13 weeks, 14…17 weeks, 18…30 weeks and over 31 weeks using the “Korm Optima Expert” software complex. The program incorporates the principle of calculating recipes at minimum cost, taking into account the restrictions on the input of each component and the nutrition of the finished product using linear programming by formulas. The expediency of replacing soybean meal in poultry feed due to its high cost for cheaper protein components is substantiated. In order to reduce the cost of compound feed, we have proposed the optimal composition of protein feed additive (PFA) for replacement soybean meal in feed recipes. On the basis of the developed recipes of compound feeds for heavy type turkeys we calculated similar recipes of compound feeds with replacement of soybean meal for PFA in their composition according to the norms of its introduction The quality indicators of finished products are in compliance with the minimum nutritional requirements of compound feeds for heavy type turkeys of a given age. The cost of compound feeds with PFA is much lower than similar with soybean meal. We determined the annual feed consumption of turkeys by growing periods based on the daily feed intake and the duration of each fattening period.

Abstract:
The article describes that there is a problem of providing the population of the planet with a complete protein in the world today. It is proved that its lack can lead to significant pathologies. This issue becomes very acute with the rapid increase in the number of people on Earth. In this situation the challenge is complicated for compound feed producers because it is necessary to provide protein feeds to farm animals and poultry to meet people's needs for animal protein products. However, feed manufacturers should not use protein raw materials that can be consumed as food. Based on cooperation with compound feed producers, the task of finding alternative sources of protein raw materials, preferably of vegetable origin, is set. The optimal composition of protein feed additive (PFA) for soybean meal replacement in compound feeds for farm animals and poultry has been developed. PFA can be manufactured at a feed mill with portion technology by weighing portions of components and mixing in a paddle periodic action mixer. PFA can be used as a part of compound feeds for poultry farms and livestock complexes, feed concentrates for poultry and livestock farms, feed mills with advanced technology, inter-farm or mini-feed mills. We have developed compound feed recipes for heavy type turkeys using PFA to determine the cost-effectiveness of using PFA in compound feed. Turkeys have been chosen as a poultry because they are the most demanding birds to the quality and quantity of protein in the ration. The experimental samples of PFA were made in accordance with the developed recipes. We determined their physical properties and chemical composition. The PFA experimental samples match the quality of soybean meal according to the physical properties and chemical composition. In accordance with the developed recipes of mixed feeds for heavy type turkeys experimental samples of starter and grower feeds were made. Research of the physical properties and chemical composition of compound feeds has shown that the replacement of soybean meal with PFA in their composition does not affect the nutritional value and technological properties of the final product.

Abstract:
Fatty acid compositions of the lipids extracted from various fish feeds (Eco-float, Blue-crown, Uncle - frances, Triton, Stretting, Crown, Jik, Shaldac, Solace, Coppens, Vital, Local sinking, Local feed, Aqualis and Local floating) vended in Lagos State were determined. These feeds were designated as Feeds A to O respectively. Feed samples were procured from major fish feed markets and fish farms within Lagos metropolis and transported to the laboratory for analysis. Methylation was carried out after oil extraction to convert the fats to their methyl esters and the fatty acids methyl esters (FAME) were separated by gas chromatography. Fatty acids were analysed using a HP Agilent 5890 system gas chromatograph equipped with SP-2330 and a flame ionization detector (FID). Results revealed that the highest values for polyunsaturated fatty acid (PUFA), saturated fatty acid (SFA) and ∑n-3 unsaturated fatty acid (HUFA) were 58.26% in feed F, 38.7% in feed M and 3.59% in feed N respectively while the lowest values for PUFA (19.76%) and SFA (15.53%) were recorded in feeds M and J respectively. The results also showed that, though feed samples were high in monounsaturated fatty acid (MUFA) (55- 22%) and PUFA (58-19%), they were low in n-3 HUFA {eicosapentaenoic acids (EPA, 20:5n-3) and docosahexaenoic acids (DHA, 22:6n-3)} with the values of 0.3-3%. The shortfall in EPA and DHA of these feeds may imply that fish fed these feeds may be nutritionally deficient in these fatty acid compositions. Thus, further manipulation may be needed to improve the value of these feeds in terms of EPA and DHA.

Abstract:
When compiling diets for productive animals, one of the indicators taken into account is the cationanion balance, which is calculated based on the content of sodium and potassium cations and sulfate and chloride anions. The cationic-anionic composition of feed is very diverse. The lack or excess of one or another cation or anion in feed can lead to disruption of metabolic processes and various diseases of non-infectious etiology.The aim of the work was to quantify and analyze the cationanion composition of feed for productive animals by capillary electrophoresis.The research was carried out in the conditions of the educational and research center for the examination of food and animal feed of the St. Petersburg State University of Veterinary Medicine. 76 samples of various feeds for productive animals were used as research materials: 19 samples of grass flour, cake, mixed feeds for cattle.The study of the cationic composition of the studied feed samples was carried out, guided by the methodology M 04-65-2010 «Feed, compound feed and raw materials for their production. The method of measuring the mass fraction of ammonium, potassium, sodium, magnesium and calcium cations by capillary electrophoresis using the capillary electrophoresis system «Kapel», and anionic composition – according to the method M 04 -73-2011 «Feed, compound feed and raw materials for their production. The method of measuring the mass fraction of water-soluble forms of chloride, sulfate, nitrate and phosphate ions by capillary electrophoresis using the capillary electrophoresis system «Kapel» (GC «LUMEX»).Thus, analyzing the results obtained, it was found that in all samples of feed for productive animals, the mass fraction of cations and anions varied depending on the type of cation or anion and feed.Determination of the cationic-anionic composition of feed is a necessary condition for the formation of a full-fledged diet that provides the body of productive animals with nutrients, which is especially important in modern conditions of intensification of animal husbandry and agricultural development.

Abstract:
Forty pigs (twenty males and twenty females) were weaned at 4 weeks of age into individual cages, and their weights and feed intakes measured daily. From weaning to 16 kg live weight they were given free access to a feed with either 134 (L) or 278 (H) g crude protein (nitrogen × 6.25)/kg fresh weight. During this period pigs on feed L grew at a slower rate and converted feed less efficiently than pigs on feed H. At 16 kg live weight they were introduced to a 6 d period of feeding when, on succesive days, they were given feeds L, H, L, H, L and H (if previously fed on L) or feeds H, L, H, L, H and L (if previously fed on H). For pigs previously given access to feed L the live-weight gain was 1061 v. 575 g/d on the days when H or L was given; the feed intake was 1078 v. 1027 g/d respectively. For pigs previously given access to feed H, the live-weight gain was 655 v. 610 g/d and the feed intake 844 v. 1071 g/d on the days when H or L were given. The interactions between the feed given previously and the feed given for the 3 d of the subsequent 6 d period were highly significant for both live-weight and feed intake. These rapid changes in feed intake and growth rate suggest that the metabolism of young pigs is extremely flexible, with a rapid rate of response to a change in the protein content of their feed.

Abstract:
Proximate composition and microbial quality of three aquarium fish feeds commonly found in Bangladesh were collected from fish feed market of Dhaka city. Significantly higher moisture content (2.12 ± 0.06%) was found in Super NovaTM fish feed while similar moisture content was detected in other two feeds (p<0.05). On the other hand ash content detected in OptimumTM and Osaka 2000TM aquarium fish feed was significantly higher than that of Super NovaTM (10.67±0.19%) (p<0.05).Protein content found in OptimumTM (42.21 ± 0.12%) was significantly higher than that of Osaka 2000TM and Super NovaTM (p<0.05). However, similar lipid content was found in OptimumTM (1.06 ± 0.03%) and Super NovaTM (1.13 ± 0.01%) aquarium fish feed which were significantly higher than that of Osaka 2000TM (p<0.05). The Escherichia coli and Staphylococcus aureus were found in all feeds. However Vibrio sp was not found in any feed. Total bacterial count was significantly higher in Osaka 2000TM feed than that of others (P<0.05). However S. aureus was significantly higher in Super NovaTM than that of others while E. coli count was significantly higher in OptimumTM fish feed than that of others (p<0.05). Nutritional quality of the aquarium fish feed was qualified to some extent to meet the minimum requirement of the aquarium fish while microbial quality indicates some degrees of deterioration which may cause diseases of the aquarium fishes. Thus proper storage condition, hygienic handling and processing should be maintained to prevent the microbial contamination in aquarium fish feeds. There should be a monitoring cell from the government to assess the quality of this expensive imported feeds for aquarist.Bangladesh J. Zool. 42(2): 283-294, 2014
