“…Also, the lowest N retention occurred with SSW (4.3% lower than CTRL). N excretion was also reported to increase in goats fed feather meal [35,36] and blood meal [18]. However, the lack of significant differences between PSW and CTRL diets regarding retained N and excreted N suggests that the part of PSW protein that is not degraded in the rumen can be digested in the small intestine to support production functions and indicates that the amino acids in the diets were being utilized with similar efficiencies [24,41].…”

“…Additionally, the few scientific reports that have described the reliability of SW for ruminant feeding have evaluated the effectiveness of bone and hydrolyzed feather meal in cattle diets [8], meat and bone meal in steers [15], poultry litter in Friesian steers [16], and slaughterhouse blood in steers [17]. Also, the authors have concluded that the PSW and SSW are significant rendering by-products with high protein content for use as protein feed ingredients for ruminants [2,18]. The content of crude protein (CP), ether extracts (EE), and ash of PSW ranged from 50 to 63%, 18 to 27%, and 9.0 to 15.5% of dry matter (DM) [19].…”

The biotransformation of poultry (PSW) and swine (SSW) slaughterhouse waste might provide protein feedstuffs, ensuring efficient ruminant systems while safeguarding the environment. The present study aimed to evaluate the potential of PSW and SSW as alternative protein feed for ruminant animals. A total of 24 lambs [25.4 ± 3.13 kg of body weight (BW), mean ± SD] were randomly allocated to one of three groups (n = 8): a control diet formulated with typical protein ingredients (CTRL) and two diets formulated with PSW or SSW meal as a protein source. Dietary inclusion of PSW or SSW did not alter (p = 0.05) dry matter intake or final BW. However, animals fed SSW showed the highest average daily gain (ADG, p = 0.04). In addition, substituting PSW and SSW improved the feed conversation ratio (FCR, p = 0.05). There were no diet effects (p = 0.05) on N intake, while fecal N excretion increased (p = 0.03) with SSW feeding. Compared to CTRL and PSW, ingestion of SSW decreased (p = 0.001) and retained N. The digestibility of crude protein and organic matter remained unchanged (p = 0.05). Additionally, there were no differences (p = 0.05) in potential microbial protein synthesis based on either protein content (SPMp) or energy content (SPMe). Similarly, potential metabolizable protein by protein (PMp) and potential metabolizable energy by protein (PMe) were not affected (p = 0.05). Overall, both PSW and SSW positively influenced the growth performance of ewe lambs. However, further studies are warranted to explore the impact of PWS or SSW feeding on rumen function, nitrogen pollution, and protein escaping the rumen into the intestine in ruminants.

“…In addition to the different industrial uses of livestock wastes such as biogas production (Li et al, 2016) or electricity (Billen et al, 2015), including different waste materials from the livestock industries for evaluation in animal nutrition is a worthwhile endeavor. Some of the waste materials which have been evaluated in animal diets include bone and hydrolyzed feather meal in cattle (Knaus et al, 1998); meat and bone meal in steers (Klemesrud et al, 1998); poultry litter in Friesian steers (Muia et al, 2001), slaughter-house blood in steers (Ayangbile et al, 1993) and feather meal in juvenile tench diets (Gonz alez-Rodríguez et al, 2014).…”

The generation of poultry slaughterhouse waste from poultry production is not only unavoidable but the amount and kinds of waste can cause environmental problems. In the present study, the potential rumen digestion of poultry slaughterhouse waste which consists of protein-rich organic residues was evaluated. The chemical composition, amino acid profile and Cornell Net Carbohydrate and Protein System fractions of these wastes was determined. Rumen digestion of poultry slaughterhouse waste was compared with two common protein sources (fish meal and roasted soybean). Three poultry slaughterhouse waste samples were collected from industrial poultry slaughterhouses and the in situ degradation was done using rumen cannulated sheep. The protein (50e63%), ether extracts (18e27%) and ash (9e15.5%) contents of different poultry slaughterhouse waste samples were different (P < 0.05). Methionine and lysine contents were similar among different poultry slaughterhouse waste sources. Difference were observed for cystine (1.2e1.7%), threonine (1.9e2.2%), arginine (3e3.5%), leucine (3.5e4.1%) and valine (2.8e3.3%) (P < 0.05). Ruminal degradation rate for dry matter, organic matter and protein were different among poultry slaughterhouse waste, fish meal and roasted soybean. The degradation parameter for protein degradation was 76% for poultry slaughterhouse waste, 79% for fish meal and 98% for roasted soybean (P < 0.05). Results revealed that there was great variation in chemical composition, protein fractioning, and amino acid profiles of different poultry slaughterhouse waste sources. Poultry slaughterhouse waste is slowly-degraded protein in the rumen and thus can be an economical and rich source of rumen undegradable protein in ruminant nutrition. This implies that the use of poultry slaughterhouse waste in ruminant nutrition has a huge potential as a cleaner product of animal feeding and prevention environmental pollution. However, further studies are warranted to evaluate the digestibility of poultry slaughterhouse waste amino acids escaping the rumen into the intestine in ruminants and to compare the biological values for the amino acids in these waste material with common ruminant feedstuffs.

“…While animal waste is commonly applied to farmland as a fertilizer, it is known to be more valuable as a feed nutrient [1]. Due to the high fiber and non-protein nitrogen content of the wastes, ruminants are best suited for utilization of the wastes [2]. Poultry Manure has a potential use as a ruminant feed in addition to its traditional use as fertilizer.…”
