IMPROVE HINDGUT HEALTH FOR


HEALTHIER COWS A new dietary supplement from Trouw Nutrition GB can help reduce the under- estimated problems caused by carbohydrate fermentation in the hindgut, reducing inflammation and increasing energy utilisation and milk production. “Farmers know that feeding high levels


of rapidly fermentable carbohydrates, especially in early lactation can result in sub-acute rumen acidosis (SARA) and take action to reduce the incidence,” comments Ruminant Technical Manager Mark Hall. “But symptoms commonly attributed to SARA like loose and frothy faeces and mucus in faeces are actually signs of hindgut acidosis which requires a different preventative strategy to SARA.” If the fermentation in the hindgut is


disrupted with an increased level of lactic acid, the consequence is that the gut barrier is damaged resulting in a condition called leaky gut. This damage to the gut lining causes inflammation which diverts energy away from milk production leading to reduced yields and higher costs per litre. An inflammatory response can use up to 1Kg of glucose in a 24-hour period, with 40 litres of milk requiring 3Kg of glucose. Lactibute has a unique mode of action


which reduces the effects of leaky gut. It contains calcium gluconate which promotes the conversion of lactic acid to butyrate. A shift towards butyrate production in the hindgut helps strengthen the gut barrier and reduces inflammation, reducing glucose lost to inflammatory response. “A healthy intestine is more efficient


at absorbing nutrients. Trials at leading Institutes around the world show that this, combined with less energy being diverted to inflammation means that cows fed Lactibute produce on average an additional 0.85kg of energy corrected milk per day throughout the lactation.” Lactibute should be fed at a rate of


16g/cow/day and can be added to TMR or included in compounds.


EVONIK EXPANDS NIR SERVICES FOR FEED RAW MATERIALS AND


FEEDS With the implementation of the ISO 12099 standard for near-infrared spectroscopy (NIR), updated and expanded calibrations for feed raw materials and feeds, along with new functionalities in AMINONIR®


Portable,


Evonik now offers its customers in the feed industry an even more comprehensive service. In addition to feed additives, such


as amino acids, and concepts for protein- reduced diets, analytical services are a component of Evonik’s system solutions for feeding farm animals in a healthy, efficient, and sustainable way. “Only those who know the exact quality


of their raw materials can use them to produce high-quality feeds that meet the animals’ needs,” says Dr. Stefan Mack, head of Service Marketing in Evonik’s Animal Nutrition business line. “Since this quality can vary greatly, determining amino acids, basic nutrients, and other raw material parameters in the feed mill or on the farm is essential.” For decades, Evonik has relied on a


combination of wet chemistry and near- infrared spectroscopy (NIR). “Through elaborate wet chemical analyses, we have created the data basis for reliable calibrations of NIR spectra,” says Dr. Ingolf Reimann, head of Analytical Services in the Animal Nutrition business line. These calibrations have recently


been carried out in accordance with ISO standard 12099. Laboratory processes and documentation have been adapted accordingly. For benchtop NIR instruments, Evonik


has expanded its broad offerings with new calibrations for various insect meals and marine species meals such as shrimp, squid, and krill, as well as for cow feed (beef cattle and dairy cows). “This enables us to provide the feed industry with new sources of protein,” says Reimann. Calibrations for a number of raw materials such as corn, fish meal and soybean meal have been updated

Portable, Evonik’s mobile


NIR service available since the end of 2020, can now also be used with an iPhone or iPad. For Android phones, the second app version is available. New functionalities include even faster first-time setup and scanning of samples, as well as integration options for barcodes and geodata. More info about AMINONIR® be found online.

DAIRY EFFICIENCY A new approach to dairy nutrition based on extensive research will help dairy farmers improve health and performance at all stages of a dairy cow’s life. Crystalyx have used their 40 years’


experience in UK ruminant agriculture to develop the first range of feed blocks specifically formulated for dairy systems from calf rearing through to milking cows. “Feed blocks are well established as an


effective method of supplementing beef and sheep to optimise performance and margins,” comments Crystalyx Technical Director Dr Cliff Lister. “Dairy farmers are facing enormous challenges with the transition away from subsidy payments, feed price volatility and tightening environmental requirements. Our dairy range will allow farmers to take a different, research-based approach to evolve their systems to meet these challenges.” The dairy range includes feed blocks for


use during calf rearing, in the growing heifer stage and during transition. For calves in the first 100 days, Crystalyx


Calf 100 promotes early rumen development and starter feed intake. As a result, dry feed intakes are increased resulting in stronger, more vigorous calves better able to withstand the stresses at weaning. The inclusion of yeast cell wall products stimulates the immune system to provide a more robust defence against future challenges. If calves are at risk of respiratory problems, Crystalyx Easy Breather contains
