This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens. Three hundred eighty-four male Ross-308 broiler chickens were used with a 23 factorial arrangement with treatments according to a completely randomized design. The morphological examinations of the intestine were carried out on 1-cm long excised segments from duodenum, jejunum and ileum. Adding wheat to the diet increased small intestine length in birds compared to other feedstuffs (P <0.05). Duodenum crypt depth and jejunum villi length were also higher in groups fed with rations containing wheat (P <0.05). Groups that received thyme essential oil and enzyme supplementation had increased length of the duodenum (P <0.05). However, the two- and three-factor interaction effects were not significant. Protein digestibility was not affected by treatment (P >0.05). Feeding wheat to broiler chickens may increase the surface area for nutrient absorption in the small intestine as compensation for the anti-nutritive activity of non-starch polysaccharides in wheat-based diets. Wheat based diets are expected to be acceptable for broilers when supplemented with appropriate enzymes or thyme essential oil.

Black Soldier Fly Larvae

Insect larvae meal has been proposed as a sustainable protein source for animal diets. This study aimed to provide information on including black soldier fly larvae meal (BSFL; Hermetia illucens) in comparison to poultry meal (PM) in the canine diet with regard to digestibility and fecal characteristics. In light of this trend, the levels of PM or BSFL meal were added to replace about 30% of dry matter of the basic extruded diet. Six Beagle dogs (BW 9.64 kg) were included in a cross-over experiment. Dogs fed a BSFL meal-based diet showed higher (p < 0.05) apparent protein digestibility (82.3%) compared to those offered a PM-based diet (80.5%). Apparent digestibility for fat was higher (p < 0.05) in groups fed the BSFL meal-based diet (94.5%) compared to those offered the PM-based diet (91.6%). The fecal consistency scores for dogs fed both diets were within an acceptable range (well-formed and firm). Fecal dry matter content was higher (p < 0.05) for dogs fed the PM-based diet (33.0%) compared to those offered the BSFL meal-based diet (28.0%). Including BSFL meal in dog food can be an appropriate source of protein without any negative effects on nutrient digestibility and fecal quality.

Eight locally available protein source ingredients in Tanzania were selected for assessment of apparent digestibility (AD) in tilapia Oreochromis niloticus, using faeces samples collected by siphoning or stripping. The selected protein source ingredients were Lake Victoria sardines (FM), brewers spent yeast (BSY), moringa leaves (ML), freshwater shrimp (FSH), marine shrimp (MSH), cattle blood (CB), duckweed (DW) and fish frames (FF). The AD (%) of dry matter (DM), organic matter (OM) and crude protein (CP) was unaffected (p > 0.782–0.901) by the faeces collection method (i.e., siphoning or stripping), with correlation coefficient (r) of 0.98, 0.99 and 0.93 between AD values for DM, OM and CP, respectively, following siphoning and stripping. The AD (%) of DM, OM, CP and gross energy (GE) in the test ingredients differed (p < 0.0001). The AD (%) of DM and OM was lowest in BSY and DW, followed in increasing order by ML, MSH, FF, FSH and CB. In general, the AD (%) of CP was high (>76%), but with a low value (46%) for DW. The AD (%) of GE was closely correlated (r = 0.96) with the AD of OM. In conclusion, FSH, MSH, CB, FF, BSY and ML have acceptable protein digestibility to be used in tilapia diet formulation.

Digesta Viscosity

Two experiments were conducted to determine the effect of xylanase (850 U g−1) supplementation of a rye and soybean meal-based diet (exp. 1) and β-glucanase (1086 U g−1) supplementation of a barley- and soybean-meal-based diet (exp. 2) on the progress of protein and starch digestion throughout the small intestine. In each experiment, 12 weanling pigs per treatment were fed the experimental diet for a 10-d period, at the end of which feed intake and weight gain were recorded and samples of digesta were collected from the small intestine, colon and rectum. Xylanase supplementation did not result in any improvement in rate or efficiency of gain, feed intake, starch or protein digestibility (P > 0.05). Digesta viscosity was increased by enzyme supplementation in some sections of the small intestine. β-glucanase supplementation resulted in a significant (P < 0.05) increase in rate of gain and improved protein digestibility in the colon and in the last three-quarters of the small intestine, but had no effect on starch digestibility. In conclusion, β-glucanase supplementation of barley/SBM-based diets for young weanling pigs was of benefit whereas pentosanase supplementation of rye/SBM-based diets was not.

In the present experiment, duckweed is evaluated as a novel protein source for dogs by incorporating Landoltia punctata into dog diets at 10%, 20% and 30%. The inclusion of duckweed resulted in significant (P < 0.001) linear decreases in DM, gross energy and crude protein digestibility. The addition of the exogenous enzyme phytase significantly (P = 0.03) improved crude protein digestibility in the diet of 30% duckweed inclusion. The inclusion of duckweed in the diets had no significant effect on palatability, but resulted in firmer stools (P = 0.003).

Abstract Objectives The objectives of this research were to determine the protein digestibility corrected amino acid score (PDCAAS) and the digestible indispensable amino acid score (DIAAS) for raw and roasted American pistachio nuts in growing pigs, and to assess the effect of roasting on these measures of protein quality. Methods Twelve ileal cannulated barrows (body weight: 60.9 ± 3.2 kg) were randomly allotted to a 2-period switch-back design with 3 diets and 4 replicate pigs per period. Roasted pistachio nuts and raw pistachio nuts (American cultivated pistachio nuts) were each added to a single diet as the only protein source, and the third diet was a nitrogen-free diet that was used to measure basal endogenous losses of AA. Experimental periods were 9 d with the initial 5 d for adaptation to the diets. On d 6 and 7, fecal samples were collected, and on d 8 and 9, ileal digesta samples were collected for 9 h each day. The PDCAAS and DIAAS were calculated according to the Food and Agriculture Organization. Results The standardized ileal digestibility (SID) of all indispensable AA, except Arg and Phe, was less (P &lt; 0.05) in roasted than in raw pistachio nuts. Raw pistachio nuts had a PDCAAS of 73 and roasted pistachio nuts had a PDCAAS of 81, calculated for children 2 to 5 yr, and the first limiting AA when compared to human requirements was Thr for both pistachio nuts. The DIAAS calculated for children older than 3 years, adolescents, and adults was 86 and 83 for raw and roasted pistachio nuts, respectively. The limiting AA in both raw and roasted pistachio nuts that determined the DIAAS for this age group was Lys. Conclusions Results of this research illustrate that raw and roasted pistachio nuts can be considered a good quality protein source with DIAAS greater than 75, however, heating conditions associated with roasting may decrease the digestibility of AA in pistachio nuts.
