“…In the current study, the egg laying rate of both Hy-Line grey and Hy-line brown hens fed with the pellet diet were higher than those fed the mash diet, which was consistent with Morgan and Heywang’s study [ 19 ]. Higher daily feed intake was found in both breeds fed with pellets, which is similar to previous reports [ 20 , 21 ] that concluded that chickens tend to consume more pellets than mash diets. The higher feed intake for pellet groups may be caused by the process of pelleting in which steam and mechanical pressure are applied to the mash to agglomerate the feed particles and improve the texture of the feed [ 22 ].…”

One of the most important factors that determine feed utilization by chickens is the feed form. Although it is generally believed that pellet diets have a positive effect on chicken growth, there are some studies that have indicated no difference between pellet and mash on chickens performance. This study was conducted to assess the effects of feed form on production performance, egg quality, nutrient metabolism and intestinal morphology in two breed laying hens. Two hundred and sixteen 25-week-old Hy-Line brown (n = 108) and Hy-Line grey (n = 108) hens were selected. Each breed was randomly allocated into two treatments with 6 replications (9 birds in each replication), which were fed mash and pellet diets, respectively. Production performances were recorded daily and egg quality traits were measured every two weeks. At 42 weeks of age, one bird per replication from each experimental group was selected for metabolism determination and intestine morphology observation. Compared with mash diets, pellet diets improved laying rate (p < 0.05), ADFI (average daily feed intake, p < 0.05), egg weight, shell strength, yolk proportion and Haugh unit (p < 0.05) in both breeds and reduced the FCR (feed conversion ratio, p < 0.05) in Hy-Line grey. The apparent digestibility of DM% (dry matter) and CP% (crude protein) were significantly higher (p < 0.05) in both breed laying hens fed pellet than those fed mash. The apparent digestibility of P% (phosphorus) and Ca% (calcium) was higher in Hy-Line grey fed pellet and was higher in Hy-Line brown fed mash. Compared to mash diets, pellet diets increased the VH (villus height), CD (crypt depth) and VCR (ratio of villus height to crypt depth) of the small intestine of Hy-Line grey, and increased the VH and CD of duodenum and ileum of Hy-Line brown. Overall, pellet diets improved production performance and nutrition metabolism through positive changes in the laying rate, feed intake, egg albumen quality and apparent digestibility of laying hens. The current findings provided support for the advantages of feeding pellets during the peak egg laying period for the two popular laying hen strains, Hy-Line brown and Hy-Line grey.

“…The pelleting benefits are widely reported in the literature ( Latshaw and Moritz, 2009 , Dozier et al., 2010 , Abdollahi et al., 2013 , Mingbin et al., 2015 , Massuquetto et al., 2018 ) and the results obtained in the present study confirm these benefits. Broilers fed pelleted diets had a better performance because of the increase in FI ( Latshaw, 2008 ), as a result of better feed apprehension and reduction of time needed to eat ( Jensen et al., 1962 , Moran, 1989 ).…”

This study aimed to assess the effect of preprocessing of corn and of physical form of diets on growth performance, carcass yield, and nutrient digestibility in broilers and also the influence of corn processing on pellet quality. A total of 1,080 male Cobb chicks from 1 to 35 D were evaluated. Birds were distributed according to a completely randomized design in a 3 × 2 factorial arrangement, with 3 types of corn processing (unprocessed, pelleted, or expanded), and 2 diet physical forms (mash or pelleted), totaling 6 treatments and 9 replicates with 20 birds. The data were submitted to ANOVA, and means were compared by Tukey's test ( P < 0.05). There was no interaction between the physical form and preprocessing of corn for any of the studied variables ( P > 0.05). The use of expanded corn in the diets before pelleting resulted in higher pellet durability index and lower amount of fines ( P < 0.05) when compared with unprocessed corn. Broilers fed pelleted diets had higher feed intake ( FI ) and weight gain ( WG ; P < 0.001), higher amounts of abdominal fat ( P < 0.05), and lower ileal digestible energy ( IDE , P = 0.05) than those fed mash. There was no effect of the feed form on nutrient digestibility ( P > 0.05). Broilers fed diets with unprocessed corn had higher FI when compared to those fed diets with expanded or pelleted corn ( P < 0.001). The use of pelleted corn resulted in lower WG than the other processing methods ( P < 0.01). The corn expansion process improved feed conversion ratio and adjusted feed conversion ratio ( P < 0.001). Inclusion of expanded corn improved the coefficient of apparent ileal digestibility of DM, CP, starch, and IDE ( P < 0.05) in comparison with unprocessed corn. It is concluded that pelleted diets improve broiler performance. The corn expansion can be used to improve physical quality of the diets and broilers growth performance and nutrient digestibility.

“…This fits with studied Ref. [24] which stated that livestock feed in form of pellets was superior in terms of digestibility, because they need less energy to be digested. Therefore, to improve pigs' ability to digest feed made from agricultural and food industry wastes in the future, it is necessary to consider the production process, to determine which kind of size or form that is easier to digest.…”

This study was undertaken with the objectives to determine the feeding effect of different levels of agricultural and food waste on growth performance and cost effectiveness in pig production. This study was conducted at Manokwari regency, West Papua Province, Indonesia. The agricultural and food industry by-products used were collected from two traditional markets, five restaurants and 15 small-scale food industries. All materials used as ration were proximally analyzed to determine their nutritional values. Average daily gain (ADG), feed consumption and feed conversion ratio (FCR) were taken to determine the pigs' performance. Feed cost using local market prices was estimated in knowing the ability of agricultural waste product and food industry to substitute commercial feed. Tabulation was used to analyse the data. The result of this research indicates that the usage of agricultural and food industries' wastes as the alternative components of pigs' feed to substitute the commercial ones does not reduce the pigs' performance and production. Among three rations that use agricultural and food industry wastes, ration with the combination of 25% waste and 75% commercial feed had the best FCR. On the other hand, a mixture of 75% waste and 25% commercial feed is the most economic one, and able to reduce the cost of feeding up to 35.86%.
