The materials of the article present data on research on the chemical, mineral-vitamin composition and nutritional value of a new feed additive from citrus pomace. The article presents the results of research on the technological line of granulation of citrus waste, established the optimal composition for granulation of citrus feed additives: sunflower meal - 20%, molasses - 5% and 75% of citrus fruits.Their chemical composition was studied, the gross content of proteins, fats, assimilated carbohydrates, including simple sugars, was determined, and the efficiency of use in the diets of farm animals was determined. The positive influence of citrus waste granulation technology has been established, which allows to obtain high-quality granules. Chemical analysis of citrus granules showed that 100 g contains: protein - 6.15 g, fat - 0.99 g, carbohydrates - 21.8 g, of which simple sugars 14 g, the energy value of this feed additive - Kcal (kJ) - 120.7 (505.7).The possibility of preparation of feed additives in the form of granules is revealed, which allows to avoid selfsorting of components and overdose of microelements and to improve the consumption of feed ingredients. The ability to prepare feed additives in the form of granules avoids self-sorting of components and overdose of micronutrients and improve the consumption of feed ingredients. The results of zootechnical researches, structure and nutritional value of average daily rations with use of citrus pomace are resulted.It was found that the introduction into the diet of dairy cows feed additives from citrus pomace during stable lactation increases the average daily expectations by 1.8 kg or 15.5%, feed costs for milk production containing 4 fat were 0.97-0, 98 feed units. When using a feed additive from citrus pomace, the nutritional value of the diet is improved due to the ratio of sugar - protein (0.62: 1 vs. 0.8: 1.2).

Abstract The consumption of poultry meat and eggs is expected to increase considerably in the nearest future, which creates the demand for new poultry feed ingredients in order to support sustainable intensive production. Moreover, the constant improvement of the genetic potential of poultry has resulted in an increased nutrient density in poultry feeds, which limits the possibility to include low quality feed ingredients. Therefore, the feed industry needs new sources of highly digestible protein with a desirable amino acid composition to substitute other valuable but limited protein sources of animal origin, such as fishmeal. With estimated 1.5 to 3 million species, the class of insects harbours the largest species variety in the world including species providing a high protein and sulphur amino acids content, which can be successfully exploited as feed for poultry. The aim of this paper is to review the present state of knowledge concerning the use of insect protein in poultry nutrition and the possibilities of mass production of insects for the feed industry. There is no doubt that insects have an enormous potential as a source of nutrients (protein) and active substances (polyunsaturated fatty acids, antimicrobial peptides) for poultry. It can be concluded, based on many experimental results, that meals from insects being members of the orders Diptera (black soldier fly, housefly), Coleoptera (mealworms) and Orthoptera (grasshoppers, locust, crickets and katylids), may be successfully used as feed material in poultry diets. However, legislation barriers in the European Union, as well as relatively high costs and limited quantity of produced insects are restrictions in the large-scale use of insect meals in poultry nutrition.

Feed Samples

A total of 160 samples of 20 Australian-sourced feed ingredients of plant origin for pigs and poultry was analysed for total phosphorus and phytate-phosphorus contents and endogenous phytase activity. The majority of total P was present as phytate-phosphorus, and these concentrations were significantly correlated in 9 feed ingredients. The endogenous phytase activity in tested feed ingredients was negligible other than for wheat, its by-products and barley. Phytate-phosphorus was determined by a standard 'ferric chloride precipitation' method, which was satisfactory for individual feed ingredients, with the exception of lupins and faba beans. It appears that phytate is more difficult to extract from these two feedstuffs, possibly because of the affinity of phytate for protein. Ferric chloride precipitation methods are not suitable for phytate-phosphorus determinations of complete feed samples containing other sources of phosphorus, which is a distinct limitation. A lesser limitation is that these methods cannot distinguish between the various esters of myo-inositol phosphate present. Given the variation of phytate contents within ingredients, particularly wheat, the desirability of determining dietary substrate levels is emphasised to take full advantage of including exogenous phytases in pig and poultry diets to reduce phosphorus excretion and abate phosphorus pollution.

The Cost

Feed remains the most important cost in animal production. The need for feed ingredients, which will reduce the cost of production, is the basis for most livestock feed and production research. Man and his livestock are in competition for the basic ingredients. Availability of such feed ingredients thus becomes the key limiting factor in poultry production, hence the need for alternative and locally available feedstuffs. The presence of undegradable and complex carbohydrate, non-starch polysaccharides (NSPs) in some alternative and locally available feedstuffs exerts some anti-nutritional properties and thus can limit their use in livestock feeding (Yoruk et al., 2006). Worse still is the fact that chickens are not capable of hydrolyzing NSPs that mask protein carbohydrate (Petterson and Aman, 1989). Exogenous enzyme supplementation has been reported to be used in poultry diets to improve nutrient utilization, the health and welfare of the birds, product quality and to reduce pollution as well as to increase the choice and content of ingredients which are acceptable for inclusion in diets (Aderemi et al., 2006). Since most work with exogenous enzymes has been carried out to evaluate its effect on feed intake and growth characteristics of broilers, the aim of this study was to investigate the effect of graded level of feed enzyme Roxazyme-G® on the performance, carcass and meat qualities of broiler finishers.

And Function

The SAAs are limiting in the major poultry feed ingredients, ranking first and fifth in soya bean meal and maize, respectively. Feed ingredients rich in protein, in particular and other nutrients, enhance Energy supply and protein accretion. Modern commercial broilers have reduced maintenance needs and high amino acid requirements, and are more responsive to protein (amino acids) than energy. Cysteine is a semi-essential amino acid belonging to the SAAs. It plays essential roles in protein synthesis, structure and function, causing growth depressing effects in broiler chicks when there is methionine:cysteine imbalance. Genetically predetermined amino acid sequences in proteins are essential for production of adequate quantities of meat, milk and eggs. Therefore, ideal amino acid ratios which conform to the requirements of broilers should be utilized. In nutrition, amino acids are equivalent to proteins, hence the shift in focus from proteins to individual amino acids, expressed as ideal ratios to lysine. The SAAs are practically relevant and have critical nutritional roles in animal nutrition with over 90% production being used to fortify animal (particularly poultry) diets. A balance in the methionine:cysteine ratio is necessary to ensure efficient utilization of the SAAs for proper growth and development in broiler poultry.

The Mean

The metabolizable energy values (ME) of 16 feed ingredients available in Australia were determined with broiler chicks of both sexes. The chickens were fed test diets in which the feed ingredients replaced dextrose in a basal diet. The mean coefficient of variation was low in each determination of ME (range 0.78 to 1.20, mean 0.94 per cent). Sex had no significant effect on the ME value of most feedstuffs with the exception of oats, where ME values were significantly higher for female than for male chicks (P < 0.05). The ME values calculated from the chemical composition of feed ingredients by means of the equations of Sibbald et al; Carpenter and Clegg; and Bolton were considerably higher than that obtained by chick assay. On the other hand ME values of cereals predicted by means of Titus's equation were similar to those obtained in this experiment and to biologically determined values of ME published in the literature. ME values of protein concentrates varied considerably when estimated either by chick assay or by chemical composition. Titus's prediction equation was considered to provide a reasonably accurate estimate of the ME value of a ration where information is available only of the chemical composition of the feed ingredients.

Poultry Diets

Twenty-four poultry diets with gross energy values ranging from 18.43 to 21.54 MJ kg-1 DM were fed to chickens using a standard metabolizable energy (ME) assay procedure. Gross energy as determined by bomb calorimetry was significantly related to gross energy as calculated from chemical composition (protein, fat, and carbohydrate), with an RSD of � 0.25 MJ kg-1 DM. Energy loss via faeces and urine (range 4.1 1 to 5.91 MJ kg-1 diet DM) was significantly related to crude fibre expressed as a percentage of the total dietary carbohydrate (range 3.7 to 8.6). The RSD was � 0.29 MJ. By treating the components of ME (gross energy and energy loss) separately, bias of biological origin was separated from random error in the prediction of ME from chemical composition.
