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.

Much research on animal feed has focused on finding alternative feed ingredients that can replace conventional ones (e.g., grains and beans) to reduce feed costs. The objective of this study was to evaluate the economic, as well as nutritional value of spent coffee grounds (SCG) and Japanese mugwort (Artemisia princeps) residues (APR) as alternative feed ingredients for ruminants. We also investigated whether pre-fermentation usingLactobacillusspp. was a feasible way to increase the feed value of these by-products. Chemical analyses and anin vitrostudy were conducted for SCG, APR, and their pre-fermented forms. All the experimental diets forin vitroruminal fermentation were formulated to contain a similar composition of crude protein, neutral detergent fiber and total digestible nutrients at 1x maintenance feed intake based on the dairy National Research Council (NRC). The control diet was composed of ryegrass, corn, soybean meal, whereas the treatments consisted of SCG, SCG fermented withLactobacillusspp. (FSCG), APR, and its fermented form (FAPR). The treatment diets replaced 100 g/kg dry matter (DM) of the feed ingredients in the control. Costs were lower for the all treatments, except FAPR, than that of the control. After 24-h incubation, the NDF digestibility of the diets containing SCG and its fermented form were significantly lower than those of the other diets (P< 0.01); pre-fermentation tended to increase NDF digestibility (P= 0.07), especially for APR. Supplementation of SCG significantly decreased total gas production (ml/g DM) after 24-h fermentation in comparison with the control (P< 0.05); however, there were no significant differences between the control and the SCG or the APR diets in total gas production, as expressed per Korean Won (KRW). Diets supplemented with SCG or FSCG tended to have a higher total volatile fatty acid (VFA) concentration, expressed as per KRW, compared with the control (P= 0.06). Conversely, the fermentation process of SCG and APR significantly decreased total gas production and VFA production as expressed per KRW (P< 0.05). Because of their nutrient composition and relatively lower cost, we concluded that SCG and APR could be used as alternative feed sources, replacing conventional feed ingredients. However, pre-fermentation of agricultural by-products, such as SCG and APR, may be inappropriate for improving their nutritive considering the increase in production costs.

Decabrominated diphenyl ether (BDE-209) is widely used as a flame retardant and is detected at high levels in the environment. Its toxicities have been reported and have attracted attention. In the present study, broilers were used to determine the response in growth performance, carcass traits, meat quality, blood profiles and antioxidant system to BDE-209 exposure at doses of 0, 0.02, 0.4 and 4 mg/kg. The results showed that BDE-209 exposure at levels of 0.02 or 0.4 mg/kg increased feed intake and decreased feed efficiency. BDE-209 altered the blood profiles, such as reducing the numbers of white blood cells, lymphocytes and neutrophilic granulocytes. As compared with the control, BDE-209 exposure significantly increased abdominal fat percentages of broilers at 64.9–159.5% and adversely affected the selected biochemical indicators, including alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine (CRE), which indicated its toxicity to liver and kidney functions. Moreover, BDE-209 exposure significantly increased plasma malondialdehyde (MDA) concentrations and decreased the activities of glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), which implied aggravating oxidant stress and decline of antioxidant capacity in broilers. In conclusion, our data demonstrated that the environmental pollutant BDE-209 adversely influenced growth performance, increased the deposition of abdominal fat, impaired antioxidant capacity and the immune system and had potential toxicity to the liver and kidney of broilers.

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.

The interest for natural antimicrobial compounds has increased due to alterations in consumer positions towards the use of chemical preservatives in foodstuff and food processing surfaces. Bacteriophages fit in the class of natural antimicrobial and their effectiveness in controlling bacterial pathogens in agro-food industry has led to the development of different phage products already approved by USFDA and USDA. The majority of these products are to be used in farm animals or animal products such as carcasses, meats and also in agricultural and horticultural products. Treatment with specific phages in the food industry can prevent the decay of products and the spread of bacterial diseases and ultimately promote safe environments in animal and plant food production, processing, and handling. This is an overview of recent work carried out with phages as tools to promote food safety, starting with a general introduction describing the prevalence of foodborne pathogens and bacteriophages and a more detailed discussion on the use of phage therapy to prevent and treat experimentally induced infections of animals against the most common foodborne pathogens, the use of phages as biocontrol agents in foods, and also their use as biosanitizers of food contact surfaces.

Different Levels

Present study was conducted to evaluate the different levels of energy to protein ratios (EPR) using food waste and black soldier fly larvae meal (FWBSFL) on growth performance and nutrient digestibility of broilers. A total of 160 one-day old broiler chicks were divided randomly to four groups and each group had 8 replicates with 5 chicks per replicate. The control diet was formulated using conventional feed ingredients with EPR of 154 for the starter period and 167 for the finisher period. The other treatments were diets with normal, low, and high EPR (154,143, and 166 for the starter period; 167, 155, and 177 for the finisher period) using FWBSFL. Feed consumption and body weight gain as well as digestibility of crude protein, crude fiber, and fat were decreased due to feeding of FWBSFL diets. Different levels of EPR using FWBSFL decreased growth performance and nutrient digestibility of broilers.

Fattening of farm animals is a way of increasing the rate of meat deposit after maturity. Its effectiveness depends on genetic status of the animal and the diet fed to the animal. In this study, performance and carcass evaluation of balami rams finished on diets with varying energy levels were carried. Forty-eight rams of Balami breed, weighing 20.75±1.50- 22.50±1.91kg were randomly alloted to four dietary energy levels (EL): 2.20Mcal/kg (EL ), I 2.40 Mcal/kg ((EL ), 2.60 Mcal/kg ((EL ) and 2.80 Mcal/kg ((EL ) for 90 days. The feed II III IV intake and daily weight gain of the animals in each treatment were determined and the average recorded. Three Balami rams were randomly selected from each treatment and sacrificed to determine the dressing percentage (DP), carcass weight (CW), fat deposit (FD) and meat yield (MY). Data were analysed using descriptive statistics and ANOVA at á . The 0.05 FBW (kg) of Balami rams in group EL , EL , EL and EL were 41.88.6±1.97, 42.12±1.84, I II III IV 46.13±1.65 and 52.24±2.50 while the FCR of animals on treatments EL (5.3±0.28) and EL I II (5.2±0.26) were higher than EL (4.7±0.82) and EL (4.0±0.65). The DP (%) were 54.9, III IV 54.9, 55.8 and 56.1, the FD (%) were 9.00,9.59,8.92 and 11.46 and the MY (%) were 75.2, 74.7, 75.5 and 72.0 for rams on EL , EL , EL and EL The results indicate that, increasing I II III IV. levels of energy improved growth performance and carcass quality of Balami rams. Therefore, higher level of dietary energy (2.80 Mcal/kgDM and 14% CP) could be suggested for optimizing growth performance and meat quality of Balami ram under fattening condition.
