Abstract: -The high cost of feed ingredients, the use of non-renewable sources of phosphate and the dramatic increase in the environmental load resulting from the excessive land application of manure are major challenges for the livestock industry. Precision feeding is proposed as an essential approach to improve the utilization of dietary nitrogen, phosphorus and other nutrients and thus reduce feeding costs and nutrient excretion. Precision feeding requires accurate knowledge of the nutritional value of feedstuffs and… Show more

“…It might actually not be the case, which could imply that most efficient animals were actually not restricted, or adversely that some less efficient animals were actually restricted. Altogether this supports the need to revisit feed formulation to fulfill the requirement of the most efficient animals and to adapt the feeding tightly and dynamically, for instance, through precision feeding techniques (Pomar et al, 2009). These kinetic differences between FCR or RFI groups described for the LWD population were also found for the other two breeds, with different magnitudes and levels.…”

“…The factorial method used to determine amino acid requirements divides the total demands into two factors: maintenance and protein growth (Sakomura & Rostagno, 2007;Pomar et al, 2009). Amino acid maintenance requirements are based on the assumption that there is a constant metabolic activity.…”

“…In theory, the content of the feed in the nutrient whose excretion is aimed to be minimized should change as frequently as possible. There are of course limits on how often this can be achieved without disruption in farm practices, although with the advances of livestock precision farming, the delivery of mixtures between two (basal) feeds to deliver the appropriate amount nutrient in the feed at group or individual level may be possible (Pomar et al, 2009). …”

“…The increases in BW gain were relatively small but associated with very small errors, which suggest that it may be difficult to observe them experimentally. There are no comparable experiments in the literature, but Pomar et al (2009 and2011) simulated the differences in performance between a three phase feeding regime and meeting the digP requirements of the pigs individually through precision feeding. They suggested that there were no differences in performance between these two feeding regimes.…”
