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...

Believe it or not, most of the encapsulation and microencapsulation techniques in use today—spray drying, spray chilling and fluidized beds, among them—haven’t evolved much since they were first introduced during the World War II era. But market...

Introduction As particle size research has continued to evolve, so has the nutritionist’s understanding of what is needed to optimize animal performance. There is a push to begin manufacturing diets of specific particle sizes to account for differences among species and growth phases. This may appear to be a relatively easy task for the feed mill; however, as the grinding limitations of the feed mill are exposed, it becomes more difficult to find a resolution...

Ingredients come to the feed processor from a variety of sources. Many of these, particularly the coarse cereal grains, require some degree of processing before they are ready to be blended into an animal ration. The process of particle size reduction improves ingredient performance during mixing and, in most cases, the nutritive value of an ingredient can be improved or more nearly realized. There are many ways to reduce the particle size of feed ingredients. Two of the most common...

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,...

The Distillers Grains Technology Council has taken the annual symposium virtual and with a new format: as an on-line webinar held in three occurrences. The first session was completed on May 13th, the second on June 10th, and this third part will take place on July 8th.
Because sponsors agreed to offset the costs of the technology,...

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...

Introduction It is generally thought that as diets are ground to a smaller mean particle size, a linear improvement in nutrient utilization and pig performance will be observed. Research has demonstrated this benefit when particle size is reduced from 1,000 microns to approximately 600 microns. However, further reduction of particle size below 600 microns has not shown consistent benefits when fed to nursery pigs and has been reported to reduce feed intake and gain in finishing...

Hello everyone. We hope you are well. I would like to know if any of you have documented the procedure or recommendation for adjusting the average particle diameter at the outlet of a roller or hammer mill. At Farmonitoring Agrotech (startup) we are developing the image processing granulometry method, which can obtain average size in 3 minutes. We have obtained differences of less than 30 microns with respect to the normal sieving method. What we want to improve now is the adjustment or...

‘Food safety’ was one of many buzz phrases for 2005. As 2006 rolls forward, we can see that the attention focused on the safety of food is here to stay. The Federal Food, Drug, and Cosmetic Act requires that pet foods, like human foods, be pure and wholesome, containing no harmful or deleterious substances. Consumers are becoming increasingly aware of the quality aspects of what they eat, as well as the quality of what they feed their beloved pets. One important aspect of food...

I have been happier the few minutes spent here. We desire more discussion on the durability of pellet feeds in water. Durability of 2 hours still floating is much desired in the fish industry. Please, how achievable. Is it possible now?

Automatic dosing systems have gradually become one of the most important areas in process plants that produce animal feed, the savings that have been achieved by reducing waste as well as the overdoses of critical raw materials have reduced significantly annual operation costs with a notable increase in quality of the final product. In summary, what is achieved by using automatic dosing systems: • We avoid cross contamination of micro ingredients • More freedom of formulation for...

Corn kernel hardness is an important agronomic trait that could be affected by environmental conditions and post-harvest practices such as drying and storage. This dissertation discuss current literature related to corn variability factors and original research showing the effects of two corn hybrids varying in endosperm hardness (average vs. hard) and three post-harvest drying temperatures (35, 80, and 120°C) on corn nutritional composition, geometric mean (dgw) and standard deviation...
