“…For reference, the moisture profile of these pellets produced and tested for durability is given in table 1. The moistures are in line with measurements of other feed products reported (Moritz et al, 2002;Hott et al, 2008;Fahrenholz, 2012). The pellets were tested for durability after a lapse of one day stored in paper feed bags at room temperature.…”

HighlightsPellet length but not width increased significantly with increasing inclusion of a pellet binder in a pelleted feedMachine vision capably and rapidly measures pellet lengthThe narrow range in pellet length measurements prevents its use as an effective discriminator of pellet qualityPellet durability index from aggressive pellet durability testing is the better discriminator of feed pellet qualityAbstract. Pellet durability index (PDI) detailed in ASAE Standard S269.4 (ASAE Standards, 2007) has been the widely accepted measure for pellet quality in the U.S. and, by extension, the measure for evaluating the effect of ingredients and pelleting process variables on the quality of pelleted feed products. The PDI is calculated as the mass percentage of intact pellets remaining after tumbling a 500 g sample in a tumbling can durability tester for 10 min. In the case where pellet quality is good, oftentimes the resulting PDI for different experimental treatments are very close in magnitude. In these situations, it is desirable to have another measurement that would allow for finer discrimination among treatments. It was hypothesized that the average linear dimensions of animal feed pellets in a unit mass sample would vary as a function of formulation and pelleting process variables for a consistent knife setting in the pellet mill. This hypothesis was tested in a study involving effectiveness testing of varying inclusion levels of a potential pellet binder in a typical corn-soy swine diet pelleted by both conventional and cold pelleting processes. Pellet lengths and diameters measured by a machine vision implemented in ImageJ matched to measurements taken manually and varied with treatments. Pellet length varied with treatments but could not be a good discriminator of pellet durability between pelleted products because of the narrow range in measurement numbers (8.53 to 11.15 mm by machine vision). With the wider range in numerical values of the PDIs obtained through aggressive durability testing (23.0% to 81.0% in a tumble can with steel hexagonal screw nuts versus 91.0% to 97.5% in a tumble can without hexagonal nuts), PDI from aggressive testing is the better discriminator of quality among pelleted products because of its greater resolution.

“…The macro-structural characteristics of pellets (percentage of intact pellets, durability, hardness, length and diameter) also have the ability to influence feed consumption and need to be given special attention. In addition, birds fed pelleted feed decrease ration waste, through which the reduction in energy used for maintenance occurs, as observed by Moritz et al (2002), Moritz et al (2003), Hott et al (2008) and Abdollahi et al (2012).…”

“…However, there was no difference between the particle sizes for the animals fed pelleted feeds (Table 8). Previous research has demonstrated that increases in pellet quality can directly improve broiler weight gain and feed conversion (Moritz et al, 2003;Hott et al, 2008;Netto et al, 2019). However, these improvements in performance normally are associated with the increase in feed intake, a fact that did not occur in this study.…”

This study aimed at assessing the effect of pelleted and expanded maize-based feeds prepared with different moisture levels (ML, 0.8 and 1.6%) particle size (PS, 650 and 850µ) of ingredients on metabolizable energy, ileal digestibility of amino acids and broiler performance. A total of 720 one-day-old male broiler chicks of the Cobb strain were used. The experiment was performed over a period of 40d (days) and birds received water and feed ad libitum. From 10 to 13d higher AMEn values were obtained for birds fed expanded feeds with 1.6% ML and 850µ PS. Higher values AMEn were encountered when adding 0.8% ML in pellet feeds with 850µ or 1.6%ML/650µ PS. Expanded and pelleted diets with 1.6% ML (independent of PS, 650 or 850µ) presented higher amino acid digestibility. For diets with 0.8% of ML, better result for the digestibility of amino acids were obtained with PS 650µ for expanded and 850µ for pelleted diets. Higher weight gain was observed in broilers fed diets with 1.6% moisture at 21 and 40d. Feed conversion was improved by adding 1.6% ML only at 21d. Regarding carcass characteristics, expanded diets combined with PS of 650µ led to a higher accumulation of abdominal fat. The birds fed expanded diets at 1.6% moisture had higher breast yields. We concluded that to increase the use of nutrients, EMAn and broiler performance, it is recommended that pelleted diets be prepared with the addition of 1.6% water to the mixer and a particle size of 850µ.

“…Hott et al (2008) tested two different inclusion levels of a mixture of moisture and mould inhibitor at both a pilot research feed mill and a commercial feed mill. Every ingredient used in a common poultry diet will contain some amount of osmotically-bound moisture, and moisture is further increased with the addition of steam in the conditioner.…”

There is a wide array of factors, of which feed formulation is one, that can drastically affect both the quality of the feed produced as well as the parameters associated with the production of the feed in the mill. It has long been the practice in commercial broiler production to pellet the feed. It has been accepted at this point that feeding a diet with high quality pellets leads to better performance compared to the same diet with low quality pellets or in mash form. On the other hand, producing a high quality pellet is not the typical result in a large feed mill. In large mills, great quantities of feed must be produced in a short time frame and this is usually accomplished by running the mill at a high production rate and pelleting the diet through a relatively thin die. This usually results in decreased conditioning time and contact with the die for the diet, and consequently a lower quality pellet results, mainly because these are the two primary locations for the physiochemical reactions such as starch gelatinisation and protein denaturation that cause pellet binding. In this review we will discuss research pertaining to the use of different grains, by-products, minerals, pellet binders and most notably feedstuff constituents and their effects on both physical pellet quality as well as feed manufacturing variables such as energy usage and production rate when the data is available. The main focus will be given to research performed within the last decade. However, we have placed no restrictions on the research referenced based on publication date as there is always quality research with pertinent findings that have stood the test of time.
