“…The negative effect of phytase on the ATTD of GE that was observed in this experiment is in agreement with a recent meta-analysis for effects of microbial phytase on ATTD of GE (Torres-Pitarch et al, 2017). However, results of some studies also indicated that there was no effect of phytase on the ATTD of GE (Zeng et al, 2016;She et al, 2018), or that the ATTD of GE increased with supplementation of phytase to diets (Kiarie et al, 2016;Dersjant-Li et al, 2017). Thus, results of this and previous experiments indicate that the effect of microbial phytase on the AID and ATTD of GE is not consistent.…”

“…The quadratic decrease in the AID of GE that was observed as phytase was added to the diets is in contrast with previous data, which indicated no effect of phytase on ileal digestibility of energy (Liao et al, 2005;Cervantes et al, 2011;Zeng et al, 2015). However, in other studies, an increase in the AID of GE with supplementation of phytase was observed (Velayudhan, 2015;Kiarie et al, 2016). The negative effect of phytase on the ATTD of GE that was observed in this experiment is in agreement with a recent meta-analysis for effects of microbial phytase on ATTD of GE (Torres-Pitarch et al, 2017).…”

An experiment was conducted to test the hypothesis that pigs fed diets supplemented with exogenous phytase reduce mucin synthesis in the small intestine, increase protein hydrolysis in the stomach, increase breakdown of phytate along the gastrointestinal tract, and increase mineral and AA digestibility. A diet based on corn, soybean meal, and canola meal was formulated to meet requirements for growing pigs except for Ca and P, which were lower than requirements. Three additional diets were formulated by adding 750, 1,500, or 3,000 units of phytase (FTU) per kilogram to the basal diet. Eight growing barrows (38.45 ± 3.06 kg) were prepared with a T-cannula in the duodenum and another T-cannula in the distal ileum. Pigs were housed individually and allotted to a replicated 4 × 4 Latin square design with four pigs and four periods in each square. Each period lasted 14 d with the initial 7 d being the adaptation period to the diets. Pigs were fed twice daily in combined amounts equal to 3.2 times the estimated requirement for maintenance energy. Results indicated that the apparent ileal digestibility (AID) and the apparent total tract digestibility (ATTD) of Ca and P increased (linear and quadratic, P ≤ 0.05)

“…The ATTD of GE (72.4%), DE (3,663 kcal/ kg), and NE (2,213 kcal/kg) values for CPCC fed in the current study were lower than the values (82% ATTD of GE and 4,183 kcal/kg DE, 2,439 kcal/ kg NE, respectively) that were reported by Kahindi et al (2014) for CPCC. However, the ATTD of GE and DE values for CPCC fed in the current study were greater than the values (52% ATTD of GE and 2,683 kcal/kg DE) that were reported by Kiarie et al (2016) for CPCC. Digestibility of energy in test feedstuff for pigs can vary depending on several factors including: 1) method of estimating energy digestibility, 2) composition of test feedstuffs, 3) dietary level of test feedstuff, and 4) age or BW of pigs.…”

Energy digestibility of CPCC fed in the current study and in the studies by Kahindi et al (2014) and Kiarie et al (2016) was determined using the same method (difference method) of estimating nutrient digestibility.

Cold-pressed camelina cake (CPCC) is a fibrous co-product of camelina seed pressing and available for livestock feeding. However, information is lacking on the effect of supplementing fiber-degrading enzymes to CPCC-based diets on nutrient utilization by pigs. Experiment 1 determined the effect of multienzyme supplementation on standardized ileal digestibility (SID) of amino acid (AA) and net energy (NE) value of CPCC for pigs. Six ileal-cannulated barrows (average initial body weight [BW] = 36 kg) were fed five diets in 5 × 5 Latin square design with 1 added column to give six replicates per diet. The diets were a corn-soybean meal (SBM)-soybean oil-based diet and the basal diet with corn, SBM, and soybean oil replaced by 25% CPCC with or without multienzyme (600 U of xylanase, 75 U of glucanase, 250 U of cellulose, 30 U of mannanase, 350 U of invertase, 2,500 U of protease, and 6,000 U of amylase/kg of diet; Superzyme-CS, 0.5 g/kg) in a 2 × 2 factorial arrangement. The fifth diet was a low-casein cornstarch-based diet. The ratio of corn to SBM and soybean oil in the basal diet was identical to the CCPC-containing diets to allow calculation of nutrient digestibility of CPCC by the difference method. On a dry matter (DM) basis, CPCC contained 42% crude protein, 10.5% ether extract, 25.4% neutral detergent fiber (NDF), 2.07% Lys, 0.73% Met, 1.64% Thr, 0.51% Trp, and 22.1 trypsin inhibitor units per milligram, respectively. The SID of Lys, Met, Thr, and Trp for CPCC were 43.5%, 70.7%, 44.8%, and 55.3%, respectively. The digestible energy (DE) and NE values for CPCC were 3,663 and 2,209 kcal/kg of DM, respectively. Multienzyme supplementation did not affect the SID of AA, and DE and NE values for the corn-SBM-CPCC-based diet, and for the CPCC. In experiment 2, the effects of multienzyme dosage (0.5 or 50 g/kg of treated feedstuff) on porcine in vitro digestibility of DM (IVDDM) of CPCC was determined. The IVDDM of CPCC was increased (P < 0.001) with an increase in multienzyme dosage. Multienzyme at 0.5 g/kg did not affect IVDDM of CPCC. However, multienzyme at 50 g/kg increased (P < 0.01) IVDDM for CPCC by at least 16%. In conclusion, multienzyme at 0.5 g/kg did not affect SID of AA and NE values, and IVDDM for CPCC. However, multienzyme at 50 g/kg improved IVDDM of CPCC, implying that the efficacy of the multienzyme with regard to improving nutrient digestibility of CPCC in pigs is dosage dependent.

“…The FDE contained galactanase, protease, mannanase, glucanase, xylanase, amylase, and cellulase activities at 50, 200, 400, 600, 1,000, 2,500, 2,800 U/g of product, respectively, and was previously validated to be effective in increasing utilization of flaxseed in broilers and roosters ( Slominski et al., 2006 ). Control diet was formulated to meet BB nutrient specifications (Cobb, 2016) and FFF diets were balanced to ensure the ratio of energy and AA contributing ingredients were similar to the control diet ( Fan and Sauer, 1995 , Adeola et al., 2016 , Kiarie et al., 2016 ). All diets contained titanium dioxide as an indigestible marker and were fed as mash.…”

The effects of coextruded full-fat flaxseed and pulses ( FFF ; 1:1 wt/wt) mixture on n-3 polyunsaturated fatty acids ( PUFA ) enrichment in egg yolk, hepatic attributes, apparent retention ( AR ) of components, and ceca metabolites were evaluated in broiler breeder hens. The diets were as follows: 1) corn–soybean control, 2) control diet plus 18% FFF ( FFF− ), and 3) FFF plus enzyme supplement ( FFF+ ) containing galactanase, protease, mannanase, glucanase, xylanase, amylase, and cellulase activities. Twenty-six-week-old Cobb 500 broiler breeder hens were allocated to 30 identical cages (2 hens/cage) and given 1-week adaptation period. The 3 diets were assigned to 10 replicate cages based on postadaptation BW and fed based on breeder curve for 30 D. Excreta samples were collected from day 24 to 27 for determination of AR of components, and eggs were collected from day 28 to 30 for yolk polyunsaturated fatty acids analyses. On day 30, birds were weighed, killed via cervical dislocation, liver weighed, and stored for fat analyses. Ceca digesta samples were taken for concentration of short-chain fatty acids. Liver and yolk weights as well as total yolk FA were not influenced by diets ( P > 0.05). Control birds had lower yolk concentration of α-linolenic acid than birds fed either FFF− or FFF+ ( P < 0.01) corresponding to 7.5, 36.8, and 37.3 mg/g for the control, FFF−, and FFF+, respectively. Control birds also exhibited lower yolk concentration of docosahexaenoic acid ( P < 0.01). Control birds had higher hepatic concentration of crude fat and apparent retention of dry matter and crude protein compared with either the FFF− or FFF+ birds ( P < 0.05). Birds fed FFF- diet had lower ceca digesta concentration of lactic acid than control and FFF+ ( P < 0.05) birds. Results showed broiler breeder hens enriched egg yolk with n-3 polyunsaturated fatty acids without effects on the liver while the supplemental enzyme did not improve the utilization of FFF.
