Welcome to the page about Feed pelletizing of Engormix; a source of knowledge on Feed pelletizing.
Ingredients are the basis of all animal feed. In times where alternative ingredients receive more and more attention, we should not forget to ask ourselves how ingredient properties affect the transition into actual feed. It is time to unravel the black box that is...
On Engormix's Spanish speaking community a great discussion has been originated a few months ago and is covering the experiences in the use of a pellet mill having 2 or 3 roll assemblies. A few manufacturer names came into the picture as CPM and Andritz being the most popular. A great debate between available surface area in the pelleting chamber verse pellet mill capacity has been created and there are some good comments/experiences from either end users or equipment manufacturers. It is my...

When it comes to poultry feed, particle size makes a big difference for bird nutrition.
Research shows that chickens increase their feed intake and performance when given pelleted feed or crumbled pellets, compared with mash.
This has led researchers to wonder whether feeding crumbles could jumpstart very early chick growth and boost final broiler body weights. It is important to study this question because pellets and crumbles are more...
John Boney (Penn State) discussed his recent research on pellets and flock uniformity in poultry farms and processing plants, during IPPE 2020 in Atlanta, USA....
I. INTRODUCTION In Tanzania, a majority of the SM farmers use mash diets for feeding broiler chickens, and this has resulted in lower performance. The feed industry in Tanzania is less developed due to lack of analytical facilities, low quality of ingredients and lack of government policy enforcement on feed quality (Geerts 2014). Improving feed quality through physical processing and microbial enzyme supplementation can enhance broiler performance. Feeding pellets improves...
The Impact of Feed Pelleting on Enzyme Thermostability In animal feed manufacturing, the process of pelleting is used to convert mash feed into compressed pellets. Pelleting provides several advantages, such as ease of handling, reduction of dust and waste and standard composition. The use of pelleted feed is also known to improve the feed conversion ratio (FCR) due to better digestibility and absorption of nutrients by the animal. During the...
Introduction With the expansion of the commercial broiler chicken industry, metabolic disorders have become emerging serious hazards in bird’s health and profitability (Savard et al., 2013). Fatty liver, among many other metabolic syndromes, has not received adequate attention in broiler research while it plays a significant role in the pathogenesis of many liver and kidney diseases and may directly cause low performance and a great economic loss (Zhang et...
INTRODUCTION The continuous growth of aquaculture production based on fishmeal (FM) is fundamentally unsustainable, since most wild fisheries stocks are already beyond their catch limits (FAO, 2018). Plant-based ingredients, such as soy protein concentrate (SPC), are sustainable products widely used by the aquaculture industry as an important source of protein (ABDUL KADER et al., 2012). Fermented SPC is an innovative product, based on aerobic SPC fermentation using the bacteria...
In the feed manufacturing industry, particle size reduction (grinding) is second only to extrusion processes (pelleting, expanders, extruders) in terms of total energy consumption. To achieve a finer grind (smaller finished particle size), energy and maintenance costs increase and, everything else being ...
Is it possible to use pellet with hopper drying machine to make sinking fish feed float? ...
Introduction The use of enzyme complex in animal feeding improves the utilization of nutrients that would otherwise be unavailable (Leite et al., 2011), reflecting positively on the performance and reducing the pollution load of excreta (Opalinski et al., 2010). However, the inclusion of enzymes in formulations should be made carefully, because this additive may lose their biological activity during pelleting process, which involves high temperatures, moisture, and...
Introduction Globally, feeding cost and the price of poultry product have recently increased due to increasing competition between human and animals for the same feed resources. Agriculture by-products are valuable feedstuffs that can be used in animal nutrition (Al-Harthi et al. 2018a, 2018b). In animal nutrition feed processing and feed additives as well have been used for improving the feeding values of feeds particularly of agricultural byproducts (Dozier et al. 2010;...
True that pellet should be hard enough to sustain handling process up to feeding. At the same time, too hard pellet may be not preferred by birds. Can anyone suggest the specification for good quality pellets for chicken? ...
1. Introduction The pelleting operation is one of the most expensive processes with regards to the fixed and variable costs. For this reason, efficient pellet production is aimed and pellet press should deliver a high yield of dust-free and resistant pellets to optimize the feed mill operations. Besides the types of ingredients,...
Integrators usually operate the mills at full capacity and outputs rather than trying to obtain the optimum pellet quality. The advantages of feeding a pelleted feed over mash have been documented in the industry for many years. The advantages include the following: Increased bulk density Less bridging/hang-up in bins Less dust Reduced ingredient segregation Less feed...
WILMINGTON, Del – DuPont Nutrition & Biosciences announced today the launch of the industry-leading novel phytase enzyme, Axtra® PHY GOLD. The enzyme offers superior performance compared to other phytases on the market, delivering greater feed cost savings to producers. Axtra® PHY GOLD will be available in the United States, Mexico and India and eventually worldwide, pending regulatory authorizations.
Recent scientific studies demonstrate that Axtra® PHY...
Introduction Pelleting is a feed processing method shown to improve handling and transportation characteristics of feeds, while reducing ingredient segregation during handling, decreasing dust levels, and improving feed utilization in swine. The use of flat die technology (cold pelleting) has received little attention at this point compared to thermal pelleting for commercial feed applications. Its unique advantage of layout (flat-bed compared to standard ring die) requires only...
Dr. Kim Koch (North Dakota State University) talked about pellet mills and production, during the 22nd Annual Distillers Grains Symposium in Des Moines, Iowa....
One problem in fish-farming is the lack of knowledge on how to produce floating pellets for Tilapia feeds. I would like to hear different skills from others on what feed ingredients are good for floating pellet production. Thanks for your time ...
1. Introduction Pelleting is the most used thermal processing method in poultry industry. The aim of pelleting processing is to agglomerate ingredients particles by mechanical action, in combination with moisture, pressure and temperature. Broilers fed pelleted diets present greater feed intake, better feed conversion ratio and greater weight gain [1-3]. The positive effect of pelleting on broiler performance is partly due to improved nutrients digestibility [4], increased feed...
