NEWS ▶▶▶ Folic acid for weaned piglets


A recent study showed that dietary folic acid supplementation can improve the growth performance and intestinal morphology of weaned piglets by maintaining the balance of epithelial cell renewal. The study evaluated the effect of dietary folic acid levels on growth performance, intestinal morphology and functions, and intestinal epithelial cell renewal in post-weaning piglets fed an antibiotic-free and zinc oxide-free diet. A total of 28 weaned piglets (Duroc×Landrace×Yorkshire; barrow; initial average body weight of 6.73 ± 0.62 kg) at 21 days of age were selected from 10 litters based on body weight and randomly assigned to four treatments. They were fed the same antibiotic-free and zinc oxide-free basal diets supplemented with folic acid at 0, 3, 9, and 18 mg/kg for 14 days. The folic acid used was a spray-dried micro-granular commercial product containing 80% folic acid using dex- trin as the carrier. Dietary supplementation with folic acid increased villus height, villus height-to-crypt depth ratio and villus surface area, and greatly increased the lactase and sucrase activities in the jejunal mucosa of weaned piglets. When it comes to intestinal morphology and improvement in functions, dietary supplementation with folic acid at 9

and 18 mg/kg significantly increased the ADG in weaned piglets. Results show that dietary supplementation with high-dose folic acid (3, 9 and 18 mg/kg) can increase the utilisation of proteins by promoting body protein synthesis and deposition. Meanwhile, dietary supple- mentation with 9 and 18 mg/kg folic acid can greatly reduce some essential amino acids content in the blood, such as Lys, Met, and branched-chain amino acids, which further supported the above conclusion. Therefore, di- etary supplementation with folic acid seems to improve the growth performance of weaned piglets by increasing both nutrient digestibility and deposition.


Upcycled groceries for pet food


Kemin Industries is working with CSS to explore the development of sustainable pet food ingre- dients from upcycled groceries. By doing this, Kemin and CSS aim to produce ingredients that are safe, healthy, tasty and nutritious for pets, and sustainable for the planet. Every year, up to 40% of food in the US is wasted, at a cost of over US$ 200 billion. Kemin Nutrisurance, the pet food and rendering technologies business unit of Kemin, is using innovative technologies from CSS’s patented Harvest to Harvest (H2H) technology to collect and repurpose recovered food from supermarkets and other food-recov- ery partners to explore the development of high-quality, sustainable pet food ingredients from upcycled groceries. “Pet parents are increasingly demanding natu- ral and sustainable solutions for their compan- ion animals. We are excited to leverage CSS’s

Recent research shows that using fermented rapeseed meal (FRSM) in sows’ diets results in better use of mineral compounds as well as improvement in the production effects and health parameters of sow and piglet blood. The scientists describe how biochemical and haematological markers of the blood can as- sess animal health and welfare. The values of these parameters depend in part on the quan- tity and quality of feed ingredients. The team studied the effect of including FRSM in a dry feeding system on haematological and bio- chemical blood parameters of sows and pig- lets. The experimental material comprised 30 primiparous gilts and 30 multiparous sows af- ter their second lactation. The diet containing FRSM which was fed to pregnant and lactating sows increased the level of haematocrit and haemoglobin and red blood cell content and mineral content (phosphorus, calcium and iron) in the plasma. This effect was mainly ob- served in primiparous sows. The inclusion of FRSM in the diet of sows reduced the plasma content of total cholesterol and triacylglycerols in sows and piglets, as well as liver enzyme ac- tivity, particularly aspartate transferase (AST) in piglets.

Although not yet receiving a full green light, dried yellow mealworms have got the initial thumbs up from the EU’s food safety watch- dog, the European Food Safety Authority (EFSA). More commonly known as the larval form of the mealworm beetle, dried yellow mealworm is deemed safe for human con- sumption in both its whole form and as a pow- der additive. There has been a lot of interest and debate on using insects. EFSA has given its determination following an application by French insect farmer EAP Group SAS – Micro- nutris, which is now known as Agronutris. However, the authorisation by EFSA is just the first step, which needs to be followed by Euro- pean Commission officials’ approval as to whether the insects can be sold as snacks or for use in other foodstuffs.
