“…Benedetti et al [134] found that birds fed coarse maize dies had 15% higher liver weight compared to those fed fine maize diets. Similar results have been reported in turkeys by Favero et al [135], who found that the diet containing coarse maize particles promoted an increase in relative liver weight compared with those containing fine and medium maize particles. In contrast to these results, Rezaeipour and Gazani [126] reported that feed particle size had no effect on liver weight in broiler chickens.…”

Despite having huge responsibilities in avian species, published reports on the influence of dietary factors and other possible constraints on the size, development and function of liver are limited. Consideration of the factors that could influence and alter liver function is therefore of critical relevance. In the current review, aspects of liver structure and function, and the influence of feed restriction, anti-nutritional factors, structural components and feed additives on liver are discussed. Effects of feed technology techniques such as thermal treatment and pelleting, feed particle size and whole grain feeding on the liver are also reviewed. A discussion of lipogenesis and lipid storage in poultry is presented to provide a better understanding and to differentiate the normal pathways of lipid metabolism from abnormal (i.e., disordered) pathways. The liver is the main site of fat synthesis in poultry, but under certain conditions, excessive fat can accumulate in the liver and cause problems. Factors contributing to the fatty liver syndrome are also examined.

“…() found that dressing carcass, breast, liver, heart, pancreas, crop, proventriculus and intestine weights were not affected by feed form. There is a positive correlation between the particle size of feed and gizzard relative weight and small intestine relative length (Favero et al., ). Large particles tend to remain in the initial portion of the gastrointestinal tract longer, thereby increasing the absorption of nutrients and, consequently, energy uptake by birds (Mai, ).…”

“…Till now, little is known about whether the visual experience of feed characteristics influences feed efficiency. Poults are much more reluctant to eat mash rather than crumbled feed, and this phenomenon is most marked in the 7–14 days of growth period (Favero et al., ). The latter authors added that feed form of the diet is also considered critical at this stage because of the aversion of turkeys to consume diets with high concentrations of fines.…”

SummaryA total number of 180 1-day old native turkey chicks were chosen in this study, for evaluating the impacts of using different attracting colours and forms of the offered feed on growth performance, carcass traits and some of health aspects, in a 3 × 2 factorial experimental design. The birds were allocated into three main groups according to feed colour (non-coloured, orange and green feeds), then each main group was divided to three subgroups corresponded to feed form (mash and crumbles feed) respectively. The obtained results indicated that feed colours and forms changed significantly the final body weight, body weight gain, feed conversion, gizzard percentage, meat juiciness, plumage conditions and mortality rate. However, there were no significant differences among the treatments in carcass traits, meat quality (percentages of heart, liver, abdominal fat colour, flavour and tenderness) and body temperature. Significant interactions of feed colours × forms groups were existed in most studied traits except in feed consumption, giblets, meat quality traits, plumage conditions and body temperature. Finally, considering the obtained results, it was observed that the native turkeys prefer green feed as crumbles over non-coloured or mash feed.Consequently, feeds for turkey chicks should be in green mash or crumbles during the growing period to maximize the profit.

“…Essential oils also have phytobiotic properties and can therefore stimulate digestive enzyme secretion, thereby improving growth and feed utilisation ( Jang et al, 2004). Finally, the ability of poultry to select feed particles according to their beak size, increases with age thus, older poultry tend to prefer larger feed particle sizes (Favero et al, 2009). These findings are in line with those of a previous study on broiler chickens that revealed a beneficial effect of herbal products (952 mg/ kg of coriander extract in drinking water) on body weight gain (Naeemasa et al, 2015).…”

We investigated the effects of different formulations of the herb Houttuynia cordata (HC) mixed with fermented red koji (FRK) as feed additives on the growth performance of ducks and the effects of adding chemical blends (alum and AlCl 3) on the pH and ammonia (NH 3) concentration of duck litter. After a 2-week brooding period, 240 one-day-old Peking ducks (160 male and 80 female) were allocated to one of four dietary groups (control, 1% HC powder mixed with FRK, pelleted 1% HC/FRK, and coated pellets of 1% HC/FRK), each with four replicates of 15 birds, and four chemical blend litter treatments (control, 50 g alum+50 g AlCl 3 , 100 g alum+100 g AlCl 3 , and 150 g alum+150 g AlCl 3 /kg duck litter) in the pens used for feeding trials. In terms of growth performance, we found that final body weight, weight gain, feed intake, and feed conversion ratio varied significantly among birds fed the different HC diets (P<0.05). Duck litter pH differed significantly during the experimental period (P<0.05), except during days 28. The additive blends had a strong influence (P<0.05) on NH 3 throughout the experimental period (not on day 7). In conclusion, adding 1% HC (in pellets and coated-pellet form) with FRK to duck diets improved growth performance and the inclusion of chemical blends (a combination of 50 g alum and 50 g AlCl 3 per kg litter as optimal rate) in duck litter in pens during the feeding trial decreased litter NH 3 concentration and pH.
