Plain-language definitions of the feed-nutrition terms our team uses on technical calls. Bookmark this page — the same vocabulary appears across our trial library, TDS sheets, and on-farm protocols.
Lecithin treated with phospholipase A2 to remove one fatty-acid tail from the parent phospholipid molecule. The 'lyso' form is more amphiphilic (HLB rises), emulsifies dietary fat at lower inclusion, and works in the immature digestive systems of monogastrics and aquaculture juveniles where adult bile and lipase capacity isn't yet in place. GIIOFEED-Ly is the liquid form; GIIOFEED-Py is the same molecule on a feed-grade silica carrier for dry premix handling.
An enzyme that hydrolyzes the sn-2 ester bond of glycerophospholipids, removing one fatty-acid tail and producing a lyso-phospholipid. Industrially used to convert standard lecithin into the lyso form (lyso-lecithin), which has higher HLB, better emulsification at lower inclusion, and improved performance in immature digestive systems.
A fat ingredient formulated so its fatty acids pass through the rumen without being fermented by rumen microbes, then are absorbed downstream in the small intestine. Lets dairy nutritionists add ration energy density without dropping rumen pH or triggering sub-acute acidosis. High-C16 rumen-bypass powders such as GIIOFAT-P-PA85 (soy-based) and Optymax PA85 (palm-based) are the most common high-bypass form.
Choline delivered in a form (typically phosphatidylcholine fraction in fractionated bypass fat, or specialty rumen-protected coatings) that passes through the rumen intact. Free choline in the diet is rapidly degraded by rumen microbes; the bypass form supports hepatic VLDL assembly during the transition-cow negative-energy-balance window. MilkGro is GIIAVA's bypass-PC bypass-fat product.
Kilograms of feed consumed per kilogram of body-weight gain (broiler, swine, fish) or per dozen eggs (layer). The headline efficiency metric in commercial animal production. LOWER FCR is better — it means less feed for the same output.
Grams of body-weight gain per animal per day. The headline growth-rate metric in broiler, swine, and aqua production. Reported per stage (starter, grower, finisher) and benchmarked against breeder charts (Aviagen Ross, Cobb-Vantress for broilers; standard tables for swine and aqua species).
Same scale (0-20) used in food: quantifies how water-loving vs oil-loving an emulsifier is. In animal feed, higher HLB emulsifiers — especially lyso-lecithin — work better at the lower bile concentrations and immature lipase systems found in young monogastrics and aquaculture juveniles.
Adding 0.5-1.0% liquid lecithin upstream of the pellet press reduces die wear, lowers press temperature, increases throughput, and improves pellet durability. The lecithin earns its keep at the press before it ever reaches the animal — and then continues to work as a digestive-tract emulsifier downstream.
The three-week pre-calving through approximately three-week post-calving window. Cows enter negative energy balance, mobilise body fat, and face elevated risk of ketosis, fatty liver, displaced abomasum, and milk-fever. Nutritional support during this window (bypass fat, bypass choline, anionic salts, propylene glycol) drives outcomes for the full lactation cycle.
Standard deviation of broiler flock body weight divided by mean body weight, expressed as a percentage. The uniformity metric. Lower CV = more uniform flock = better processing yield at slaughter. Inadequate fat absorption in the 0-21 day window widens CV by week 3.
Chain-of-custody documentation that traces non-GMO soya from farm through crushing, refining, and ingredient manufacture. The 'N' suffix in the GIIAVA SKU (e.g. GIIOFEED-Ly-N) indicates the source is IP-traceable non-GMO soya, eligible for Food Chain ID and equivalent retailer-specified non-GMO certifications.
Survival rate from PL1 (one-day-old post-larva) through PL15-PL20, the hatchery window before grow-out. Industry benchmark is 80%+; many operations sit at 55-65%. Dietary phospholipid supplementation supports membrane assembly demand in this period — the larva cannot yet synthesise phosphatidylcholine fast enough on its own.
16-carbon saturated fatty acid. Highest melting point of common dietary fatty acids — passes the rumen intact, doesn't ferment, and is absorbed downstream where it supports milk-fat synthesis in the mammary gland. High-C16 rumen-bypass fat (GIIOFAT-P-PA85, >85% C16) is the established lever for raising milk-fat % in dairy nutrition.
