Abstract This study was conducted to determine the digestible energy (DE), metabolizable energy (ME), and ileal digestibility of amino acids (AA) of fish protein hydrolysate (FPH), and to evaluate the effects of FPH on the performance of piglets. In Exp. 1, the available energy content of FPH was determined by difference methods: 12 barrows with an initial body weight (BW) of 40.0±2.1kg were randomly assigned into two dietary treatments with six replicates per treatment, the treatments contained a corn basal diet and an experimental diet in which 20% corn was replaced by FPH. The experiment was lasted for 12 days, with 7 days adaptation period followed by 5 days total collection of feces and urine. In Exp. 2, the standardized ileal digestibility (SID) of AA in FPH by the N-free method was determined, 12 barrows (initial BW of 35.3±1.8 kg) with ileal T-cannulas were randomly allotted into two treatments with six replicates per treatment, the dietary treatments consisted of an experimental diet and a N-free diet. The experiment was lasted for 7 days, with 5 days adaptation period followed by 2 days collection of ileal digesta. In Exp. 3, the effect of FPH on the performance of piglets was conducted. 192 piglets (initial BW of 8.10±1.8kg) were randomly allotted into four treatments with six replicates per treatment. The treatments were a control diet with fish meal (FM) and part or all FM was replaced by FPH, got diets containing 2%, 3% or 5% FPH. The experiment lasted for 28 days. Results showed that: In Exp. 1, the DE and ME of FPH were 21.12MJ/kg and 20.28MJ/kg. In Exp. 2, the SID of Lys, Met, Thr and Trp were 79.99%, 87.17%, 68.29%, and 71.53% respectively. In Exp. 3, addition of 3% FPH increased nutrient digestibility and volatile fatty acid content in feces. Addition of 5% FPH increased the average daily feed intake (ADFI), significantly increased (P<0.05) the activities of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and immunoglobulin A (IgA), while significantly decreased (P<0.05) the average daily gain (ADG). In conclusion, FPH had a high value of digestible energy and ileal digestible essential amino acids, could improve nutrient digestibility, immunity, antioxidant capacity, and intestinal health of piglets, while adverse to nitrogen deposition in piglets.

Abstract The objective of this study was to determine the effects of an Aspergillus oryzae prebiotic (AOP, Amaferm®) on nutrient digestibility in growing pigs fed high fiber diets. Eighteen growing barrows (initial BW = 50.60 ± 4.90 kg) were surgically equipped with a T-cannula at the distal ileum. Three diets were formulated by including 29.65% corn-distillers dried grains with solubles (DDGS), 36.65% rice bran (RB) or 24.59% wheat middlings (WM) in corn and soybean meal-based diets to meet nutrient requirements for 50 to 75 kg growing pigs. Three additional diets were formulated by supplementing 0.05% AOP at the expense of corn in DDGS (DDGS + AOP), RB (RB + AOP), and wheat middlings (WM + AOP) diets. Pigs were allotted randomly to a triplicated 6 × 2 Youden square design with 6 diets and 2 successive periods. Feces and ileal digesta were collected for 2 d after a 21 d adaptation period, and nutrient content was analyzed to calculate apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID). Standardized ileal digestibility (SID) of amino acids was calculated by correcting AID with basal endogenous amino acid losses determined from the same set of pigs. Supplementation of 0.05% AOP increased (P < 0.05) ATTD of DM, GE, CP, NDF, and ash in DDGS, RB, and WM diets. Diet DE was 35 kcal/kg greater (P < 0.05) in pigs fed AOP supplemented diets compared with those fed diets without AOP. Pigs fed DDGS+AOP diet had greater (P < 0.05) AID of ether extract compared to those fed DDGS diet. However, supplementation of AOP did not (P > 0.05) affect AID of GE, DM, CP, NDF, ash or SID of amino acids. In conclusion, supplementation of AOP in high fiber diets containing DDGS, RB, or WM increased total tract energy value and nutrient digestibility.

Abstract The objective was to determine the influence of amino acid (AA) supplementation during the adaptation period on the ileal digestibility of crude protein and AA in corn and soybean meal (SBM). Six barrows with an initial body weight of 30.9 ± 2.6 kg fitted with a T-cannula in the distal ileum were assigned to a 6 × 6 Latin square design with 6 dietary treatments and 6 periods. Two experimental diets contained corn or SBM as the sole source of AA and an N-free diet was additionally prepared. For AA supplementation groups, an AA mixture consisted of Gly, Lys, Met, Thr, Trp, Ile, Val, His, and Phe was added to the corn diet and the N-free diet at the expense of cornstarch, and an AA mixture of Lys, Met, and Thr was added to the SBM diet. All diets contained 0.5% of chromic oxide. The 6 experimental diets were fed to the pigs for 4 and half days, and the 3 diets containing AA mixture were switched to the respective diets without AA mixture during the following 2 and half days. Ileal digesta were collected during the last 2 days. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Arg and Trp in corn (P < 0.05), but did not affect that in SBM. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Pro and Gly regardless of feed ingredient (P < 0.05), but did not affect that of other AA. All AA except Pro in corn and SBM were unaffected by the addition of AA mixture during the adaptation period. In conclusion, the addition of amino acid during the adaptation period does not affect the standardized ileal digestibility of indispensable amino acids in feed ingredients.

Abstract An experiment was conducted to test the hypothesis that addition of crystalline amino acids (AA) to diets during the adaptation or collection periods will not influence calculated values for apparent ileal digestibility (AID) or standardized ileal digestibility (SID) of AA in corn and soybean meal (SBM). Seven ileal-cannulated barrows (initial body weight: 77.9 ± 2.6 kg) were allotted to a 7 × 7 Latin Square design with 7 dietary treatments and 7 periods. Dietary treatments included feeding diets based on corn or SBM without or with crystalline AA for the entire 7-d period or with crystalline AA during the adaptation period, but without crystalline AA during the collection period. An N-free diet was also used. Each experimental period consisted of 5 d of adaptation to the diets followed by 2 d of ileal digesta collection, with digesta being collected for 9 hr/d starting after feeding the morning meal. Thus, the entire experiment lasted 49 d. The AID and SID of crude protein (CP) and AA were calculated using values determined in corn or in SBM without or with crystalline AA to determine if crystalline AA influenced calculated values for AID or SID of CP and AA. Results indicated that addition of crystalline AA to diets fed during the entire 7-d period increased (P < 0.05) AID of some AA in corn and SBM. However, no differences in SID of CP and AA were observed between pigs fed the diets without crystalline AA and pigs fed the diets with crystalline AA if dietary crystalline AA were ignored in calculations of SID values. This indicates that crystalline AA were 100% absorbed before the distal ileum and did not affect calculated values for SID of AA if calculations were based only on the AA in corn or SBM. Therefore, it is concluded that crystalline AA may be added to experimental diets in digestibility experiments before and during collection periods without affecting results, if crystalline AA are disregarded in the calculation of AID or SID of AA in ingredients.

Abstract The objectives were to determine standardized ileal digestibility (SID) of amino acids (AA) in hatchery byproducts fed to nursery pigs and to test the additivity of ileal digestible AA concentrations in hatchery byproducts. Ten barrows (initial body weight = 11.3 ± 1.3 kg) surgically fitted with T-cannulas at the distal ileum were individually housed in pens. Four diets were prepared to contain 30% of infertile eggs, unhatched eggs, culled chicks, or a mixture (20% dried infertile eggs + 20% dried unhatched eggs + 60% dried culled chicks) as the sole source of nitrogen. A nitrogen-free diet was additionally prepared to measure basal endogenous losses of AA. All experimental diet contained 0.5% chromic oxide as an indigestible index. Ten pigs were assigned to a replicated 5 × 4 Latin square design with 5 diets and 4 periods. Each period consisted of a 5-d adaptation period and a 2-d collection period. The hypothesis was that the determined digestible AA concentrations of the mixture are not different from the calculated values based on digestible AA in the individual ingredients. A t-test was used to determine the additivity of digestible AA concentrations in individual ingredients. Infertile eggs had greater (P < 0.05) SID of all indispensable AA except for lysine and methionine compared with culled chicks. The SID of all indispensable AA except for tryptophan was not different between culled chicks and the mixture. The calculated apparent and standardized ileal digestible AA in the mixture were not different from the determined values, but calculated ileal digestible tryptophan in the mixture was less (P < 0.05) than the measured value. In conclusion, ileal digestibility of most indispensable AA in infertile eggs is greater than that in culled chicks and ileal digestible AA values are additive in the mixture except for tryptophan.

Fish Protein Hydrolysate

Fish is one of the most important foods in the human diet because of its high nutritional quality. One of the potential local foodstuffs in Grobogan is Nile tilapia (Oreochromis niloticus). Nile tilapia has a high nutrient content, especially protein. To obtain better benefits from fish protein, it can be processed into fish protein hydrolysate (FPH) products. Fish protein hydrolysates (FPH) which contain a mixture of small protein or peptides and free amino acids are beneficial for children diet, in preventing and combating malnutrition problems through readily absorbed essential amino acids. This study aimed to analyze the amino acid profile of Nile tilapia and fish protein hydrolysate (FPH) from Nile tilapia. The treatments included processing Nile tilapia into hydrolysate and analyse amino acids of Nile tilapia before and after hydrolysate. The process of making FPH uses a local microbial protease enzyme from Bacillus licheniformis. Amino acids composition was analysed using an internal method developed by Saraswanti Indo Genetech laboratory (18- 5-17/MU/SMM-SIG, UPLC). Data were analysed using the paired t-test statistical test. The results showed there were significant differences in the rate of all amino acid profiles (p<0.05), except L-Aspartic Acid, L-Tyrosine and L-Histidine (p>0.05). From the research, it can be concluded hydrolysate processing has an effect on the increase of Lglutamic acid and L-lysine amino acid.

Abstract Three experiments were conducted to investigate the effects of dietary crude protein (CP) level and N-carbamylglutamate (NCG) supplementation on apparent total tract digestibility (ATTD) and ileal digestibility of nutrients and digestive enzyme activity of jejunum in growing pigs. In experiment 1, 10 Duroc × Landrace × Yorkshire barrows (initial BW: 48.7 kg) were allotted to a three-period switchback design with five experimental diets and two replicate pigs per diet in each period. Diets were categorized as high CP (HP, 18% CP), moderate low CP (MLP, 15% CP), very low CP (VLP, 12% CP), and MLP and VLP with 0.1% NCG supplementation. Feces and urine were collected from day 6 to day 11 after a 5-d adaptation period. The DE, ME, and ATTD of GE, OM, CP, NDF, ADF, and P decreased (P &lt; 0.01) with a reduction of dietary CP, but no effect of dietary treatments on pig daily N retention was detected. The NCG supplementation increased (P &lt; 0.01) DE and ATTD of ADF of the VLP diet. In experiment 2, 10 jejunal-cannulated Duroc × Landrace × Yorkshire barrows (initial BW: 44.5 kg) were fed five diets for three periods as experiment 1. Jejunal fluid was collected on days 6 and 8 after a 5-d adaptation period. The digestive enzymes activity was not affected by dietary CP level, except for α-amylase, for which there was a decrease (P &lt; 0.01) in pigs fed VLP diets compared to HP and MLP diets. In experiment 3, 12 ileal-cannulated Duroc × Landrace × Yorkshire barrows (initial BW: 46.7 kg) were allotted to a three-period switchback design with six diets and two replicate pigs per diet in each period. The six experimental diets consisted of five experimental diets as experiment 1 and one N-free diet. Ileal digesta was collected from day 6 to day 8 after a 5-d adaptation period. Results indicated that apparent ileal digestibility (AID) of CP and P and ileal digestibility of Arg, His, Ile, Leu, Phe, and all dispensable AA, except Pro, decreased (P &lt; 0.01) in pigs fed VLP diet compared to HP and MLP diets, but AID of GE, OM, EE, NDF, and ADF were not affected. The supplementation of NCG in the VLP diet increased (P &lt; 0.01) the AID of CP and ileal digestibility of Arg, His, Leu, Phe, Val, Ser, and Tyr. In conclusion, reducing dietary CP level decreased nutrient digestibility, but improved the efficiency of dietary N utilization and reduced N emission. Moderate reduction of dietary CP level had a minimal effect on nutrient digestibility and digestive enzyme activity. Additionally, NCG supplementation plays a beneficial effect on nutrient digestion only if the dietary CP level is extremely lowered.
