Nutritive value of multienzyme supplemented cold-pressed camelina cake for pigs

Abstract

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.

Cold-Pressed Oilseed Cakes as Alternative and Sustainable Feed Ingredients: A Review

“…HSC and LSC had the highest average SID of EAA, 87.8 and 85.1%, respectively [18]. According to Woyengo et al [23], the average SID of EAA for CSC (54.8%) was close to the average value (57.9%) reported by Kahindi et al [47]. In contrast, higher values of SID of EAA were observed by Almeida et al [37] for CSC (68.6-77.7%).…”

“…Apparently, the application of the heat to the barrel during oil extraction led to an increase in TTAD of energy due to the rise in lipid solubility, which might affect improvement in energy digestibility of pressed cake [16]. The TTAD-GE for CSC ranged between 72.4 and 82.0% [23,29,47]. The net energy (NE) and digestible energy (DE) for CSC were noted to be in the range of 9.3-10.7 MJ/kg and 15.3-17.5 MJ/kg, respectively [23,29,47], while NE and DE for RSC were reported to be 8.6-11.9 MJ/kg and 13.2-16.5 MJ/kg, respectively [10,16].…”

The differences in energy values among oilseed cakes were attributed to differences in the species of oilseed and their chemical composition, as well as the conditions of pressing employed [29].…”

Nutritive value of enzyme-supplemented carinata meal for growing pigs1

“…Thus, the limited effect of phytase and multicarbohydrase supplementation on AID of GE could be attributed to the lack of effect of the enzyme supplementation on ileal digestibility of AA. Similarly, supplementation of cold-pressed soybean cake ( Woyengo et al, 2016 ) or cold-pressed camelina cake ( Woyengo et al, 2018 ) with multienzyme did not affect AID of GE in pigs. Supplementation of carinata meal with phytase and multicarbohydrase improved the ATTD of GE, which was due to numerical increase in AID of GE and AHD of GE by the enzyme supplementation.…”

“…The negative effects of fiber and phytate in carinata meal can potentially be alleviated by supplementing fiber-degrading enzymes and phytase, respectively. Supplemental fiber-degrading enzymes have been shown to improve the nutritional value of various Brassica co-products including canola meal ( Zijlstra et al, 2010 ), rapeseed meal ( Fang et al, 2007 ), and camelina cake ( Woyengo et al, 2018 ).…”
