“…Tolkamp et al (2010) recently provided further evidence in support of the view that enzymatic production can also be altered via selection for growth rate and feed efficiency (Pym 1985;Doeschate et al 1993) but not by selection for leanness (Leclercq and Saadoun 1982). Investigations by Péron et al (2007) showed evidence for variation in proventriculus pepsin activity between lines subjected to different selection pressures, which leads to differences in protein digestive efficiency.…”

“…The digestive efficiency of a modern commercial production breed was shown to be lower than that of a high digestive efficiency line (Carré et al 2002(Carré et al , 2008Péron et al 2007), indicating that selection strategies have not led to the maximum potential digestive efficiency broilers are capable of. In both the experiments carried out by Carré et al (2002) and Péron et al (2007), broilers were placed on modern wheatbased diets.…”

“…There is a selective tendency for the gizzard to increase in absolute size when the birds are selected for high digestive efficiency (Maisonnier et al 2001). This adaptation becomes more pronounced if selection takes place on a diet where the physiochemical properties of the grains make the feed tougher to mechanically breakdown (Péron et al 2007). Furthermore, the gizzard can be stimulated into growing larger in low digestive efficiency lines when fed on coarse grains, thus improving bird digestive efficiency.…”

“…In both the experiments carried out by Carré et al (2002) and Péron et al (2007), broilers were placed on modern wheatbased diets. When placed on similarly soft wheat grain-based diets (Sideral and Sciphon wheat, respectively), the commercially breed showed moderate digestive efficiencies of protein, starch and lipid when compared with the lines specifically selected for high and low digestion efficiencies.…”

Artificial selection of broiler chickens for commercial objectives has been employed at an unprecedented magnitude over the recent decades. Consequently, the number of days, total feed and in turn energy, required to raise a broiler to slaughter weight, have decreased dramatically. Feed provision is the poultry industry's biggest environmental hotspot; hence, understanding the interactions between the birds' genetic change and their energy use efficiency forms the necessary starting point for quantifying and predicting and thereby mitigating the future environmental impact of the poultry sector. This review assesses the consequences of artificial selection on the following traits: digestive efficiency, body composition and utilisation of metabolisable energy for growth and metabolic activity. The main findings were (1) the digestive system has been subjected to much physical change due to selection in the recent decades, but this has not led to any apparent change in digestion efficiency. (2) Both the energy intake per day and the metabolic heat production rate have increased in the recent decades whilst (3) the efficiency of utilising energy for growth has also increased; this is due to an increased growth rate, so that broilers reach slaughter weight more quickly and therefore need to allocate less energy overall to metabolic processes, with the exception of growth. (4) There may have been a reduction in the tendency to waste feed through spillage and carry out energetically expensive behaviors. There is a discrepancy in the literature with regards to the influence of selection on body composition and its contribution to feed efficiency. In this review, two scenarios are demonstrated, whereby body composition either has or has not altered via artificial selection. Understanding the effects of artificial selection on the traits that relate to the feed efficiency of the broilers will contribute towards the reduction of the environmental impacts that arise from such systems.

“…In the caeca, buckets containing glucose, amino acids or nucleosides were highly positively correlated with DE. The glucose may come from higher starch digestibility associated with the more developed gizzards in D+ broilers 3 , 26 and with higher pepsin activity in the proventriculus 27 . The link between nucleosides (deoxycytidine, deoxyguanosine) and DE (positive correlation) may come from higher liberation of nucleoside in caeca due to higher renewal of intestinal mucosa, bacterial DNA or differences in the ability of caecal enterocytes to absorb nucleosides 28 .…”

The increasing cost of conventional feedstuffs has bolstered interest in genetic selection for digestive efficiency (DE), a component of feed efficiency, assessed by apparent metabolisable energy corrected to zero nitrogen retention (AMEn). However, its measurement is time-consuming and constraining, and its relationship with metabolic efficiency poorly understood. To simplify selection for this trait, we searched for indirect metabolic biomarkers through an analysis of the serum metabolome using nuclear magnetic resonance (1H NMR). A partial least squares (PLS) model including six amino acids and two derivatives from butyrate predicted 59% of AMEn variability. Moreover, to increase our knowledge of the molecular mechanisms controlling DE, we investigated 1H NMR metabolomes of ileal, caecal, and serum contents by fitting canonical sparse PLS. This analysis revealed strong associations between metabolites and DE. Models based on the ileal, caecal, and serum metabolome respectively explained 77%, 78%, and 74% of the variability of AMEn and its constitutive components (utilisation of starch, lipids, and nitrogen). In our conditions, the metabolites presenting the strongest associations with AMEn were proline in the serum, fumarate in the ileum and glucose in caeca. This study shows that serum metabolomics offers new opportunities to predict chicken DE.
