Ensuring the profitability of feed processing

Feed mills are fundamental to animal production. The high milling efficiency of modern feed mills contributes significantly to ensuring secure supplies of food of animal origin for the human population.Compound feed production is a complicated operation that requires processing of a heterogeneous mixture of several ingredients into uniform pellets. Feed mills are now facing important challenges. These include ensuring profitability and safety of milling operations. There are wide variations in prices and often in supply of feed raw materials. Energy costs, consumer demands, regulatory requirements, competition pressure and low prices for livestock products are all factors, which impact upon feed mill profitability. Other areas that will pay dividends are sustainability and process control automation to reduce variability and improve data collection and record keeping. Securing feed profitability and productivity Feed mill operators have done just about all they can to increase feed profitability by reducing costs at the raw material level. There are additional ways to increase feed production profitability and feed processing productivity. Good pellet quality is important as it brings several benefits such as compaction which reduces the volume of the feed, saving transport and storage capacity. Good pellets have a homogeneous shape and are stable in transport and storage, which will reduce loss from dust or fines. Good quality pellets with little dust or fines are usually well accepted by the animals avoiding selective feed ingestion by the animals. Importance of pelleting The pelleting process can be evaluated by the following criteria; pellet quality (expressed as abrasion index), feed processing productivity and energy consumption. Energy use is significant in feed manufacturing and needs to be reduced as part of a sustainability programme and from an economic standpoint. To enhance energy efficiency and productivity, pellet quality and mass throughput the die dimesinons need to be optimised. Feed manufacturing is a complicated and expensive business and to maintain feed profitability it is important to ensure that all aspects of the manufacturing process are optimised. Good monitoring of the process and data collection becomes increasingly important to manage the modern feed mill. Customised program for feed millers Through product development, equipment manufacturing and engineering technology, Kemin is able to make substantial contributions to improving the profitability of feed manufacturing. The company has designed a customised program for feed milling customers called MillSmart. According to Kemin, the program increases feed mill profitably and process productivity by reducing energy costs, improving throughput, pellet quality and providing higher production output. It also ensures feed safety. The Millsmart programme is now available in many of the 90 markets in which Kemin operates. In today’s world, all improvements that can be made to optimise the bottom line in feed production through introducing interventions to improve processor are very welcomed by feed manufacturers. Through securing an efficient production process, a competitive advantage can be generated. The feed mill is no longer seen as a cost-centre but with the customised programme as a tool to optimise the feed value and feed mill operations.

Policy options needed to reduce further use of antibiotics

Despite global efforts to reduce antimicrobial use in livestock animals, experts project that the use will increase in the next 15 years if no measures are taken.In the review article, published in Science and compiled by a range of experts around the world, it is stated that in 2013, the global consumption of all antimicrobials in food animals was estimated at 131,109 tons. It is projected to reach 200,235 tons by 2030. The projection is based on veterinary antimicrobial sales volumes that were obtained via public records for 38 countries and self-governing dependencies. The experts found consumption levels to vary considerably between countries, ranging from 8 mg/population correction unit (PCU) (a kilogram of animal product) in Norway to 318 mg/PCU in China. The review article proposes some solutions to reduce the antibiotic use and hence AMR resistance in the upcoming years. These may include: Regulations. A global regulation putting a cap of 50 mg of antimicrobials per PCU per year, the current global average amount, could reduce total consumption by 64%. If only countries of the Organization for Economic Cooperation and Development (OECD) and China were to adopt this regulation, the global consumption in 2030 would already be reduced by 60%. Meat consumption. Limiting meat intake worldwide to 40 g/day, the equivalent of one standard fast-food burger per person, could reduce global consumption of antimicrobials in food animals by 66%. This reduction is comparable with what could be achieved through regulations targeting antimicrobial use. User fees. Imposing a user fee of 50% of the current price on veterinary antimicrobials could reduce global consumption by 31%. More important, such a policy would also generate yearly revenues between US$ 1.7 billion and 4.6 billion. Achieving meaningful reductions Luckily, many efforts are taken to reduce the antibiotic use in the coming decades. In Europe, regulations have been the principal instrument to limit antimicrobial use in animal production. In the US, consumer preferences have driven companies to reduce antimicrobial use in animals, although the impact on livestock rearing practices is still nascent. As the largest consumer of veterinary antimicrobials, both in relative (per PCU) and in absolute terms, China has an important leadership role with regard to its response to AMR and has already set precedents in phasing out drugs that are last resorts for human infections but are still in use in Europe in animal husbandry. To provide a good global analysis, it is important that all countries have a good monitoring system in place. Many countries already do this, but unlike for human medicine, there is currently no global database (public or private) on veterinary antimicrobial sales accessible to the public health community. Although present data are limited, outlining current knowledge allows inferences to be made about the relative impact of different policies to curb antimicrobial use. The expert findings suggest that imposing a user fee on veterinary antimicrobials is a plausible policy option to achieve meaningful reductions in antimicrobial use in the short term while simultaneously raising funds to improve farming practices that will benefit the long-term viability of the livestock industry.

Benefits of latest NIR developments

Recent developments in near infrared (NIR) spectroscopy are extremely cost-effective, near instant and provide on-site analysis. This will benefit animal nutritionist to formulate better livestock diets.Feed costs account for up to 80% of the total variable costs of animal production, and both diet formulation and quality control are a major focus for feed manufacturers and producers. Any deviation from target specification that either under- or over-supplies nutrients will translate directly into economic losses through higher feed costs or lower animal performance. However, traditional methods of laboratory-based feed analysis are time-consuming and costly, with the delay between sampling and receiving results restricting any ability to respond to deviations in the nutrient profile of incoming feedstuffs or finished feed. Recent developments in near infrared (NIR) spectroscopy that enable extremely cost-effective, near instant, non-destructive on-site analysis therefore have the potential to deliver substantial benefits throughout the animal production industry. Currently used for basic raw material and feed quality control, new advances in NIR software and hardware are set to deliver commercially viable systems capable of in-line and real-time monitoring of feedstuff and feed nutrient content and physical characteristics. Losses associated with feed ingredient variability can be reduced, feed formulations can be amended and the quality of completed diets continuously monitored. The ability to economically test a far larger number of samples from each feed batch will also dramatically improve overall accuracy. Compact NIR devices have many advantages The latest compact NIR devices makes it possible to analyse feedstuffs before use, or even before purchase, with quality control possible at any point along the production, delivery and consumption chains. Performance of these compact NIR devices is comparable to laboratory based NIR instruments, but have the advantage that analysis can be taken to farm-level. In addition, software developments have allowed web-enabled NIR analyses in which NIR spectra are downloaded to a master machine containing appropriate calibrations that are stored and updated centrally. The advantages include more regular updating of calibrations, whilst customers will have the option to purchase calibrations on a per sample basis, if preferred. For the worldwide feed industry, these benefits are potentially worth several billion dollars annually thanks to a combination of feed cost savings, feed manufacturing efficiencies and more predictable animal performance. Reducing ingredient losses A recent study (Table 1) showed that the energy value of different cereals can vary by around 1.5Mj; and about the same level of variation can be found within one feedstuff. With energy worth between €5 and €20 in feed, and more than 500 million tonnes of mono-gastric feed being produced per year, it is easy to see why the energy value of feed is so economically important. Heat damage can also affect the precision and cost effectiveness of diet formulation. As lysine is heat-processed, it loses its nutritional value – meaning that reactive lysine (a measure of available lysine after digestion) needs to be analysed.

BergaPur: Re-formulation of a highly concentrated phospholipid complex

Berg + Schmidt has re-focussed its phospholipid product group. The re-formulation of the highly concentrated phospholipid complexes sold under the name “BergaPur” is based on the latest research results. In this way, the Hamburg company has created a natural feed additive designed to improve both the biological performance and the production process in modern feeding strategies. BergaPur is a high-quality, readily digestible phospholipid complex in powder form, produced by deoiling crude lecithin. In animal nutrition, the addition of phospholipids to the feed eases the process of digestion in the small intestine and ensures a supply of choline, inositol, essential fatty acids and phosphorus. In the production process BergaPur acts as a lubricant, thus increasing the throughput of pellet presses and extruders and reducing abrasion. Furthermore, BergaPur prolongs the shelf life of the feed and improves its stability. International research findings confirm the positive effect of BergaPur on the animals’ performance and vitality. It is consistent implementation of these results that forms the basis of the innovative BergaPur product line. High-class feeding strategies are the basic requirement for efficient and safe processing in the feed industry. They have a considerable influence on the animals’ health and ensure nutrient supply according to the animals requirements. In order to achieve this, the feed must be made up optimally from individually selected components and additives. Re-formulated BergaPur makes it possible to optimize feed production processes to meet these requirements and ensure profitability.
