“…The inclusion of FBM did not determine a reduction in performance variables in any of the studied processing methods. These results are similar to those found by Xavier et al (2011), who evaluated increasing levels (0, 2, 4, and 6%) of FBM in the broiler starter diet and observed no effects on weight gain, feed intake, or feed conversion. Nevertheless, the diet with FBM turned out to be economic, as it increased nutrient and energy diversity in poultry diets.…”

“…In experiments conducted with the same ingredient evaluated in this experiment, Xavier et al (2011) observed that the inclusion level of 6.0% in broiler pre-starter diet worsened performance up to 21 days of age, eliciting a negative linear response from weight gain and feed intake, but no changes in feed conversion. The authors recommended the inclusion of 3 to 4% in the broiler pre-starter and starter phases.…”

“…Feathers are included in practical feeds as part of the protein and amino acid source (Branco et al, 2003;Saima et al, 2008;Baker, 2009). Xavier et al (2011) described that up to 6% FBM can be included in diets for broilers in the pre-starter (one to seven days old) and starter (eight to 21 days old) phases. Carvalho et al (2012), however, stated that the inclusion of 5% feather meal impaired the performance of birds at 35 days of age.…”

The objective of this study was to evaluate the inclusion of feather and blood meal (FBM) in broiler pre-starter and starter diets according to the processing method used. Performance, digestibility, and intestinal morphometry of broilers fed diets containing FBM were evaluated in two experiments, in the pre-starter (1-7 d) and starter (8-21 d) phases in a randomized block design with four treatments and five replicates of 12 birds, totaling 20 experimental units per trial. The criteria used for block formation was the battery floor. The meal was processed under different degrees of hydrolysis pressure (2.0 kgf/cm 2 for 40 min; 2.5 kgf/cm 2 for 30 min; and 3.0 kgf/cm 2 for 20 min) and added at 9% to the pre-starter (Experiment I) and starter (Experiment II) diets. In each experiment, 480 male Cobb 500 ® chicks were allocated to batteries. The following variables were measured: live weight, weight gain, feed intake, feed conversion ratio, and digestibility and retention of dry matter, nitrogen, and ether extract. Performance was not influenced by the dietary inclusion of the ingredient. However, FBM subjected to the highest hydrolysis pressure resulted in the worst overall nutritional balances. The chickens were more susceptible to FBM processing in the prestarter phase, when the hydrolysis pressure of 2.5 kgf/m 2 for 30 min provided the best results. In the starter diet, FBM processed at a hydrolysis pressure of 2.0 kgf/m 2 for 40 min provided the best performance results up to 14 days of age, without changing nutrient metabolism. Up to 9% feather and blood meal can be included in broiler prestarter and starter diets as long as the ingredient processing method is well-known.

“…The lower feed intake observed in quails fed with highest levels of FM justify the results observed for the weight gain. Several researchers have indicated a maximum limit of 4% inclusion of FM without any loss of performance (XAVIER et al, 2011;ROSTAGNO et al, 2011). However, Holanda et al (2009) evaluated increasing levels of FM inclusion in diets for broiler chickens, aged seven to 42 days, and concluded that up to 8% may be employed without any loss in production.…”

“…The inclusion of feather meal (FM) in poultry diets reduces costs without negatively affecting performance. It also increases abattoirs' profits, especially for poultry integration, offering low costs in food production and poultry diet and a decrease in environmental pollution (BELLAVER et al, 2005;XAVIER et al, 2011;KHOSRAVINIA et al, 2015). Hydrolyzed FM is produced by cooking nondegraded feathers, obtained during the slaughter of poultry, under pressure.…”

The objective of this study was to evaluate the effect of the inclusion of feather meal (FM) in diets supplemented with protease for meat-type quails, on performance from eight to 21 days and from eight to 35 days of age and on carcass yield cuts and economic profitability from eight to 35 days of age. A total of 360 male, meat-type quails, were allotted to a completely randomized design, in a factorial 3 x 3 arrangement (three diets and three FM levels of inclusion), with four replicates of 10 quails per experimental unit. The diets evaluated were positive control (PC) + 0% FM, PC + 5% FM, PC + 10% FM, negative control (NC) + 0% FM, NC + 5% FM, NC + 10% FM, NC + 0% FM + protease, NC + 5% FM + protease and NC + 10% FM + protease. The NC diet was formulated with a reduction in crude protein and amino acids, compared to the PC diet. There was an effect (p < 0.05) of the inclusion of FM in diets on feed intake, weight gain and feed conversion ratio, from eight to 21 and from eight to 35 days of age. There was a significant effect (p < 0.05) of FM inclusion on the live weight of 35-day-old quails. The inclusion of FM impairs meat-type quails’ performance at all ages evaluated. NC diets, with and without protease, worsen the performance of birds compared to PC diets. Better economic profitability is observed for up to 5% inclusion of feather meal in positive control diets.

Large amounts of waste, including dead birds, manure, and poultry litter, are produced by the poultry industry. Poultry waste should be disposed of properly to avoid major pollution and health risks. Composting litter and dead birds could be an option to recycle the waste and use in poultry feed. A study was conducted to investigate the effects of feeding composted poultry waste on the organoleptic qualities and compositional profile of the meat of broiler chickens. A total of 300 day-old broiler chicks (500-Cobb) were randomly allocated to five treatment groups replicated six times with 10 birds each, under a completely randomized design (CRD). Five iso-caloric and iso-nitrogenous diets including composted poultry byproducts at concentrations of 0, 2.5, 5, 7.5, and 10% were fed ad libitum to the birds from day 0 to day 35. The sensory grading and meat composition profile of 500 Cobb broiler chickens were tested at 35 days of age. The findings showed that there were no variations in the sensory profiles of the meat from birds given various diets (P>0.05). Although the results were somewhat lower for the chicks fed compost-containing diets than for the control group, this difference was deemed to be insignificant (P>0.05). Similarly, there were no variations in the compositional profile values of the meat between meat from birds fed various diets (P>0.05). These findings imply that broiler chickens may be raised on diets containing up to 10% poultry byproduct compost without any negative impacts on the meat's sensory quality or composition. Additionally, using compost into broiler diets may help to lower the cost of feed.
