New information on the use of feed fats, medium-chain fatty acids and deoiled lecithin

At its stand at EuroTier 2018 in Hannover (hall 20, stand no. B26) Hamburg feed specialist Berg +
Schmidt will be presenting, from 13 to 16 Nov. 2018, findings from the company's latest trials showing how feed additives can be used even more efficiently on dairy, pig and poultry farms. The applications research findings focus on positive results obtained with Lipo-Vital, Berg + Schmidt's latest range of products based on medium-chain fatty acids, in terms of gut health and resilience of piglets and broilers. Moreover, the role of deoiled lecithin in boosting feed conversion rates in weaners was examined and new results were obtained about the effects of fractionated feed fats on dairy cows at the early and mid lactation stages. Berg + Schmidt offers a wide range of feed additives and continuously runs trials aimed at optimizing their use.
Producers who wish to reduce the use of antibiotics and improve the intestinal health and resilience of their livestock will find LipoVital especially interesting. In collaboration with partners in the compound feed industry B+S examined the effects of LipoVital GL-90 when applied to raising piglets. Benefits of LipoVital GL-90 include both its high degree of purity - 90% glycerol monolaurate - and its specific effect. Unlike free fatty acids the product is not corrosive and its neutral taste and smell make it highly palatable to young animals. LipoVital can be supplied as a raw material at 90% purity or as a customized compound. Even at low dosages of 0.1 - 0.3% it achieves excellent results and, in critical cases, the dose may be increased to as much as 0.5% without problems.
At present Berg + Schmidt is working with Rostock University, Germany, to conduct trials with LipoVital GL-90 with broilers. In addition to the usual measurements to document weight gain and feed conversion ratio etc., any histological and bade no logical changes in the small intestine will be recorded, in order to evaluate the product's anti-microbial properties and effects on intestinal health in detail.
In the two weeks following weaning BergaPur, Berg + Schmidt's deoiled lecithin product, is helpful in easing the young piglets' transition to solid feed and aids digestion. In collaboration with the north German Lehr- und Versuchszentrum Futterkamp (research center. Chamber of Agriculture of Schleswig-Holstein), Berg + Schmidt investigated the effects of deoiled lecithin on weight gain, feed intake and feed conversion ratio during different stages of rearing piglets. The trials revealed that the use of BergaPur improves feed conversion ratio and weight gain during the entire production cycle, but the first two weeks after weaning are a particularly delicate penod. BergaPur has a beneficial effect on the digestibility of fat and supplies important ingredients such as choline and inositol which aid normal liver functioning. The advantage of BergaPur compared with crude lecithin is that its phospholipid content is considerably higher and, being availablein powder form. it is easier to add to feed mixes.
During early lactation, roughly from the 20th day onwards, low daily doses of about 250 g of the rumen by-pass fat powder BergaFat F-100 are enough to ensure an appreciable increase in milk yield. During mid lactation the ideal daily dosage is up to 450 g in order to partition energy resources primanly into milk production. These were the conclusions from a feeding trial conducted by Berg + Schmidt in collaboration with AddVise and DairyLink in Chile. The partners in research investigated the effects of rumen by-pass fats on the quality and quantity of milk from pasture-grazed Chilean cows in early and mid lactation. They were seeking to discover the correct dosages of BergaFat F-100 in order to improve milk yield and increase protein and fat content during these two phases. Whereas in recent years the trials conducted in North America focussed on the use of fractionated feed fats during mid and late lactation using corn based diets, B+S has now gained new insights into the optimum dosage of fractionated feed fat during early and mid lactation of grazing cows.
At present Berg + Schmidt is working with Cornell University, New York State, on trials to assess the bio-availability of rumen by-pass methionine. Moreover, the latest research is concentrating on the effects of lecithin on the metabolization of rumen by-pass fats. An important issue here is to ensure optimum liver health. Trials are also planned on the use of deoiled lecithin in feed for laying hens.
At the EuroTier 2018 trade fair Berg + Schmidt occupies stand no. B26 in hall 20, Fairground Hannover.
