Precision feeding can significantly reduce feeding cost and nutrient excretion in growing animals
Precision feeding is an agricultural concept that relies on the existence of between-animal variation and involves the use of feeding techniques that allow the right amount of feed with the right composition to be provided at the right time to each pig of the herd. Precision feeding is proposed as an essential approach to improve nutrient utilization and thus reduce feeding cost and nutrient ex...
متن کاملIn vivo threonine oxidation in growing pigs fed on diets with graded levels of threonine.
Threonine oxidation to glycine was investigated in vivo in twelve growing pigs (27.4 kg live weight) fed on one of the following three diets with graded levels of threonine supply: a low-threonine diet (LT), a control well-balanced diet (C) or a high-threonine diet (HT), during 10 h constant infusion of L-[1-13C]threonine and [2-3H]glycine in the cranial vena cava and [1-14C]glycine in the port...
متن کاملMeat quality of “Nero Siciliano” pigs fed with different diets
The effects of two different feeding strategies used during the fattening period on the meat quality of 24 “Nero Siciliano” pigs were examined. Animals were divided into two groups called Acorn (A) and Barley (B), consisting of 12 animals each, homogenous for live weight and sex. The trial was carried out over a period of 90 days. After slaughtering, Longissimus lumborum (Ll) muscle samples wer...
متن کاملFeeding behavior of growing-finishing pigs reared under precision feeding strategies.
The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 ± 2.2 kg) over 84 d. Five different feeding programs were evaluated, namely a conventional 3-phase program in which pigs were fed with a constant blend of diet A (high nutrient density) and diet B (low nutrient density) and 4 daily phase-f...
متن کاملMetabolizable Energy in Feeding Systems for Pigs and Poultry
The major consideration in this paper is the suitability of a metabolizable energy system for pigs. For poultry there is no practical alternative since urine and faeces are voided conjointly. The correction to digestible energy of a feedstuff for energy in urine is usually small, but there are circumstances when this may be large. Furthermore there are insufficient data on metabolizable energy ...
