The increasing demand for animal products has increased the demand of feed ingredients around the world. However, the decrease in natural resources, cultivated lands, and resulted in continuous supply of feed ingredients. For this reason, studies on alternative feed ingredients are the main interest of scientists. Olive industry by products are one of the major environmental pollutant and these by-products could be potential alternative feed ingredients for livestock /poultry industry. Studies have reported that the reuse of olive by-products in broiler feeding has an impact on environmental, economic and growth performance. Current review will provide the information that olive industry by-products can be used efficiently in broiler feeding. It will also contribute to the elimination of environmental problems caused by the breakdown of such wastes in the environment. However, maintaining the nutritional value, preservation methods and feed incorporation level in order to include these unconventional feed sources in the diet of farm animals is another problem that needs to be studied. This study will provide the evidence that olive industry by-products not only will increase the growth performance of broilers, but increase the olive industry profit and reduce environmental pollution. Keywords: leaves, olive, pomace, pulp, waste recycling.

Acid oils (AO) and fatty acid distillates (FAD) are oil refining by-products rich in free fatty acids. The objective of this study is their characterization and the identification of their sources of variability so that they can be standardized to improve their use as feed ingredients. Samples (n=92) were collected from the Spanish market and the MIU value (sum of moisture, insoluble impurities, and unsaponifiable matter), lipid classes, fatty acid composition, and tocol content were analyzed. Their composition was highly variable even between batches from the same producer. As FAD originated from a distillation step, they showed higher free fatty acid amounts (82.5 vs 57.0 g/100 g, median values), whereas AO maintained higher proportions of moisture, polymers, tri-, di-, and monoacylglycerols. Overall, the MIU value was higher in AO (2.60–18.50 g/100 g in AO vs 0.63-10.44 g/100 g in FAD), with most of the contents of insoluble impurities being higher than those in the guidelines. Tocol and fatty acid composition were influenced by the crude oil’s botanical origin. The calculated dietary energy values were, in general, higher for AO and decreased when a MIU correction factor was applied. The analytical control and standardization of these by-products is of the outmost importance to revalorize them as feed ingredients.

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.

Demand for poultry meat and eggs is increasing at a faster pace due to its good quality, nutritive values, and reasonable price. With the growing demand for egg and poultry meat, the demand for poultry feed is also increasing. Most of the feed ingredients which are used in poultry feed are also used for human nutrition. So these major feed ingredients and cumulatively poultry feed are facing market competition with increased cost. This study proposed linear programming (LP) technique to minimize the feed cost for small scale poultry farms. It employs locally available feed ingredients to formulate the broiler starter and finisher feed mix. The dietary nutrient requirement for broiler starter and finisher stage were determined from the prescribed standard specifications by Indian standard institutes and National Research Centers, Indian Council of Agricultural Research (ICAR). Sixteen feed ingredients were selected to formulate the optimal feed mix to minimize the total cost of feed mix subject to the essential nutrient constraints. Microsoft excel solver was used for the formulation of liner programming model and optimal feed mix for broiler starter and finisher were obtained.

Abstract The Korean poultry industry produces more than 4,000 tons of hatchery by-products (HBPs) every year. There is an increasing interest in the use of HBPs as a feed ingredient in The Korean feed industry. However, limited information regarding nutritional values for HBPs has been available. Thus, we conducted an experiment to measure apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids (AAs) in 4 different HBPs for broiler chickens. Four HBPs included infertile eggs (IFE), unhatched eggs (UHE), low grade and dead chicks (LDC), and mixture (MIX) containing 55% IFE, 10% UHE, 10% LDC, and 25% hatched eggshells. A total of three-hundred-thirty-six 21-d-old Ross 308 broiler chickens were randomly allotted to 1 of 4 dietary treatments with 7 replicates per treatment. Each diet contained individual HBP as a sole source of AAs. Additional 125 birds were used to estimate ileal endogenous losses of AAs. Results indicated that the AID and SID of 5 essential AAs (Arg, Met, Trp, His, and Val) for LDC were greatest (P < 0.05), but those (Arg, Met, and Trp) for MIX were the least (P < 0.05) among 4 HBPs. The AID and SID of most AAs in IFE were comparable to those in UHE. However, the AID and SID of 3 essential AAs (Lys, Leu, and Phe) were not different among 4 HBPs. The average AID and SID of both essential and nonessential AAs (18 AAs) for LDC were greatest (P < 0.05), but those for MIX were the least (P < 0.05) among 4 HBPs. In conclusion, HBPs used in this experiment contain high amounts of digestible AAs, which are comparable to other animal by-products. Generally, AAs in LDC are more digestible than AAs in other 3 HBPs (UHE, IFE, and MIX).

Abstract Potato and its by-products became a promising both food and bioenergy resource. The determination of the bacteriaantagonists influence on phytohormone status and productivity of potato tubers was studied. The indole-3-acetic acid content during the dormancy end and germinating in the tubers treated with Bacillus subtilis Ch-13 was fewer than in the control samples. L-tryptophan significant quantity compared to the control was found in the treated tubers in a state of physiological dormancy (more than 2-fold) and especially during active germination (43 times greater). Average potato yield increase at treated fields was of 18.8 %.
