Abstract: 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 excretion. The potential impact of using precision feeding techniques on feeding cost and nitrogen (N) and phosphorus (P… Show more

“…This is consistent with the simulation of Pomar et al (2011) who found substantial reductions in P excretion through individual precision feeding as opposed to threephase feeding; the latter met the digP requirements of the average of the population at the start of each phase. These findings cannot be compared directly with literature; when phase feeding has been practiced experimentally both the P and N content of the feed has changed simultaneously (Lenis, 1989;Coppoolse et al, 1990;Henry and Dourmad, 1993), and there is no direct correspondence between the feeds and animals used in the experiments and the simulation.…”

“…Strategies to decrease P excretion by pigs Pomar et al, 2011). In theory, the content of the feed in the nutrient whose excretion is aimed to be minimized should change as frequently as possible.…”

“…However, it must be noted that the technology is still premature and hardware and software needs further development before industry wide implementation. For example, such a system [9] requires continuous monitoring of growth and feed intake and algorithms are needed to process this information and predict future individualized P requirements.…”

“…These can be broadly divided in to two categories: improving or optimizing P availability in feed [4 ,7], and increasing efficiency of livestock through increased P incorporation in product or faster growth [8]. Matching animal P requirement with available P in the diet through accurate predictions [9], ration formulation methods and feeding animals in groups according to their physiological state reduces P excretion drastically. Phosphorus availability can also be substantially improved in monogastric animals by using enzymes such as phytase that break down organic P (Table 1).…”

“…Recommendations for populations are often determined as a requirement of an average sow without considering the between-animal variation. When these recommendations are applied to populations exhibiting large between-animal variation, the requirement of a certain percentage of the population is not met (Brossard et al, 2009;Hauschild et al, 2010;Pomar et al, 2011), and the mean performance of the group will be lower than expected. Nutrient requirements vary greatly between animals of a given population and each animal follows individual patterns over time (Pomar et al, 2011).…”
