POULTRY NUTRITION ▶▶▶
decrease nutrients availability and negatively affect the bene- ficial effects of pelleting. Winowiski (1985) for example, demonstrated that adding high moisture or high tempera- ture to the mash feed resulted in lower pellet quality and re- duced production rate.
Effect on animal level Temperature and retention time in conditioning can affect feed production, pellet quality, and consequently bird perfor- mance. The main advantage of feeding pellet to farm animals is the improvement of growth performance through feed in- take, weight gain and feed conversion ratio (FCR). Birds fed a pellet diet compared to those which receive a mash diet con- sume less energy for example. Bedford et al., (2002) demon- strated that weight gain and FCR decreased when tempera- ture in the conditioner was increased. Amirabdolahian et al., (2014) reported that pellets, produced at 72°C compared to 82°C, significantly increased feed intake in broilers (1-49 days of age). They also showed that pellets, conditioned under 82°C, improved FCR in broilers. The researchers explain these effects as being the result of breaking down disulfide bonds during the conditioning process, hence increasing digestibili- ty of nutrients in the intestine. An added effect is that condi-
tioning at high temperatures (like 82°C) reduced the microbi- al load (pathogens) and can therefore improve FCR. Attar et al., (2017) showed that conditioning feed with 70°C steam for two or four minutes could numerically improve FCR in finish- er broilers (24-45 days of age). They concluded that improved FCR in broilers may be due to the physical quality of condi- tioned feed compared to non-conditioned one and an im- provement in PDI and hardness was observed in conditioned pellets. Abdollahi et al., (2011) reported that steam condition- ing feed with 60°C, 75°C and 90°C improved weight gain in starter broilers compared to dry conditioning. The improve- ment of FCR in broilers fed conditioned feed compared to non-conditioned may be attributed to starch gelatinisation, enhanced energy digestibility and reduction of anti-nutri- tional factors (like trypsin) in the feed. Conditioning of the feed mash can increase the quality of the pellet. The conditioning process can gelatinise starch in grains and make crystalline structure of starch available for enzyme reactions, which lead to better nutrient digestibility at animal level. The benefits gained from conditioning the feed before pelleting is of particular interest in young birds (animals) that still have an undeveloped enzymatic system and therefore need highly digestible nutrients.
