Abstract Background: Weaning is associated with growth decline and morphological changes in the gastrointestinal tract of the pig. Insects, such as the Black soldier fly larvae (BSFL), are suggested as a sustainable novel protein source in diets for pigs. They contain chitin, medium chained fatty acids, and anti-microbial peptides, which could improve the gastrointestinal function and health in the post-weaning pig. The objective of this study was therefore to investigate the effect of increasing inclusion of full-fat BSFL in diets for post-weaning pigs on growth performance parameters, digestibility, gut morphology, and the microbial community in the colon. Eighty crossbred weanling pigs were weaned at approximately 32 days of age, with an average weaning weight of 10.6 ± 0.8 kg. For four weeks, the pigs were fed one of four dietary treatments: a control diet or one of three diets containing an increasing amount of full-fat BSFL meal: 4.76% (BSFL5), 9.52% (BSFL10), and 19.06% (BSFL20). Results: Increased level of full-fat BSFL in the diet did not affect growth performance or fecal consistency. A reduction in apparent total tract digestibility (ATTD) of crude protein (P = 0.035) was found for increased inclusion of BSFL, whereas the ATTD of crude fat increased (P<0.001). Jejunal, ileal, or colonic morphometry was not affected by the BSFL inclusion. Some changes in the colon microbiota were observed, but no differences in the short-chain fatty acid concentrations were detected between the dietary treatments. At the phylum level, dietary treatment affected the relative abundance of Bacteroidota, Firmicutes, Campilobacteria, and Thermoplasmatota, but there was no clear pattern relationship with the BSFL inclusion level. At the genus level, the inclusion of BSFL in the diet reduced the relative abundance of Lactobacillus (P = 0.015) compared to the control. Conclusions: Collectively, the results indicate that up to 19.06% of full-fat BSFL meal could be included in a balanced diet for PW pigs without affecting growth performance, gut function, or health.

A study was conducted at the Abubakar Tafawa Balewa University (ATBU) Research and Teaching Farm between December and May 2006 to determine nutrient intake, digestibility and growth performance in Yankasa rams fed urea-treated (UTRS) and untreated rice straw (URS) with supplementation. Thirty-two (32) Yankasa rams with an average weigh of 17.5kg, and aged 1.5 to 2 years old were alloted to eight (8) dietary treatments with four (4) rams per treatment in a 2 x 4 factorial design. The two basal feeds were urea0treated rice straw (UTRS) and untreated rice straw (URS). The supplements were maize bran (MB), MB + sun-dried poultry litter (MB + SDPL), MB + ensiled poultry litter (MB+ EPL) and MB + cotton seed cake (MB + CSC). Total dry matter intake (TDMI), daily basal feed intake (DBFI) were significant (P<0.05) across dietary treatments. Animals on supplements MB and MB+CSC for both UTRS and URS recorded the lowest and highest DBFI. The digestible crude protein intake (DCPI) and digestible organic matter intake (DOMI) were high for rams on UTRS and the values ranged from 17.72 to 28.36g/d and 288.81 to 482.66g/d for DCPI and DOMI respectively. Nutrient digestibility was improved by treatment of straw and supplementation. However, crude protein digestibility was similar for animals fed URS but, significantly (P<0.05) lower compared to those fed UTRS which were also similar across supplements. Average daily weight gain ranged from 53.58 to 91.18g/d across dietary treatment with animals on supplement MB recording the lowest (53.58 and 61.43g/d for URS and UTRs respectively) and those fed supplement MB+CSC the highest (81.38 and 91.18g/d fro URS and UTRS respectively) irrespective of straw treatment. Feed conversion ratio (FCR) was least for animals on supplement MB+CSC for both URS and UTRs, indicating that this supplement (MB+CSC) influenced feed utilization more positively. From the results of this trial, it may be concluded that straw treatment and/or supplementation can enhance crop residue utilization by sheep. however, mixed supplements especially MB+CSC were more efficient in enhancing the utilization of the straw and consequently animal performance.

Conventional feed resources for livestock are increasingly becoming more expensive, due to competition with man; hence nutritionists are searching for cheaper, locally-available alternatives. A total of forty-five (45) mixed sex weaner rabbits, aged 5 – 6 weeks, with average initial weights of between 694.42 and 761.10 g were used to investigate the effect of varying levels of cowpea milling waste (CMW) diets on their growth performance and nutrient digestibility. They were randomly allotted to five dietary treatments with nine rabbits per treatment. The control treatment (T1) contained 0 % CMW while treatments T2, T3, T4 and T5 had 10, 20, 30 and 40 % CMW dietary inclusion levels, respectively. Clean water and feed were offered ad libitum daily to the rabbits, and record of their feed intake and growth performance were taken for 12 weeks. At the end of the 11th week, a nutrient digestibility trial was carried out. Results show that there were no significant (P>0.05) differences in final body weight, body weight gain, total feed intake and mortality among the dietary treatments. Feed conversion ratio (FCR) for diets T4 (6.65) and T5 (6.66) containing 30 and 40 % CMW respectively, were as good as that of the control diet (6.11). Dry matter and crude protein digestibility showed no significant (P>0.05) difference across the treatments. Digestibility of crude fibre (72.64, 80.16, 84.04 and 80.90 % for T2, T3, T4 and T5 respectively), ether extract (95.98, 94.90, 96.04 and 94.38 % for T2, T3, T4 and T5 respectively), nitrogen free extract (94.30, 95.18, 93.58 and 94.90 % for T2, T3, T4 and T5 respectively), as well as total digestible nutrient (83.69, 76.11, 81.67 and 80.02 % for T2, T3, T4 and T5 respectively) of the test diets compared favourably with that of the control diet (72.94, 95.23, 96.04 and 80.47 % for CF, EE, NFE and TDN respectively). Hence, it can be concluded that CMW can be used safely as a protein source and included up to 40 % in weaner rabbit diets with no detrimental effect on their growth performance and nutrient digestibility.

Pre gelatinized cassava grit (PGCG) is a new cassava product produced mechanically and commercially for poultry feeding. Five dietary treatments were formulated with PGCG replacing maize at 0, 25, 50, 75 and 100 % in broiler starter (0-4 weeks) and finisher (4-8 weeks) diets. Two hundred (200) day-old broiler chickens were allotted to the five dietary treatments in a completely random design.  Each treatment was replicated four times with 10 birds per replicate and 40 birds per treatment. At the end of week 4 and 8 of the experiment, data were collected on growth performance, nutrient digestibility, haematological and serum biochemical indices. Final weight and weight gain were significantly (P < 0.05) highest in broilers fed 25 % PGCG diet, followed by those fed control diet. While, (P < 0.05) similar and lower values were obtained from broilers fed other PGCG diets. Feed intake decreased (P < 0.05) with PGCG in the diets at the starting and finishing phases. Dry matter and crude protein digestibility was (P < 0.05) highest in starting broilers fed 25 % PGCG diet, while digestibility (P < 0.05) declined with higher levels of PGCG. At the finishing phase, digestibility of all nutrients was similar (P < 0.05). Apparent metabolizable energy was (P < 0.05) higher in birds fed PGCG diets in the starting and finishing phases. Haematological and serum biochemical indices showed no significant (P>0.05) difference in the broiler chickens fed varying levels of PGCG in the diets. Broiler chickens fed PGCG above 25% in the diet had significantly (P < 0.05) higher proventriculus values when compared with those fed the control diet and 25% PGCG diet. The study revealed that substituting maize with 25 % PGCG in broiler diets improved growth and nutrient digestibility. Reduction in weight gain and non significant increased thiocyanate at higher PGCG inclusion should be improved for effective utilization of pre gelatinized cassava grit in broiler diets.

The effects of instant noodles waste (INW) as a replacement for maize was investigated using 144 day-old, unsexed broiler chicks of Anak strain which were randomly assigned into four dietary treatment groups of 36 birds each. Each dietary treatment group had 3 replicates of 12 broilers per replicate. These four different diets were fed, in which INW replaced maize at 0% (control), 10, 20 and 30% from day old to 8 weeks of age. The growth performance, nutrient digestibility, haematological parameters and carcass traits of the chickens were evaluated. Average final live from 1559.44 g to 1730.91g with broilers fed control diet and 30% INW diet recording the highest and least values respectively among the treatments. Broilers fed the 30 % INW had lower (P< 0.05) live weight. Broilers fed INW based diets had higher blood profile comparable to the control. The results indicated that INW can replace up to 20% of broiler starter diet and 30% replacement of maize at the finisher phase without adverse effects on growth performance of the broilers.

AbstractTwo experiments were conducted to test the hypothesis that a corn-expressed phytase increases growth performance, bone measurements, and nutrient digestibility by young growing pigs, if added to diets that are deficient in Ca and P. In Exp. 1, 60 pigs (initial BW: 10.78 ± 0.67 kg) were randomly allotted to 6 dietary treatments that included a positive control diet (PC; 0.70% total Ca and 0.60% total P) and a negative control diet (NC; 0.50% total Ca and 0.42% total P). Four additional diets were formulated by supplementing the NC diet with 250, 500, 1,000, or 1,500 phytase units (FTU)/kg. Diets were fed for 28 d and the individual BW of pigs on days 1 and 28 were recorded. Fecal samples were collected from days 25 to 27 to calculate apparent total tract digestibility (ATTD) of Ca and P. On the last day of the experiment, all pigs were euthanized, and the left femur was removed and analyzed for ash, Ca, and P. Results indicated that growth performance, ATTD of Ca and P, and bone ash measurements were reduced (P < 0.05) in NC fed pigs compared with PC fed pigs. However, growth performance, ATTD of Ca and P, and bone ash measurements were improved (linear and quadratic, P < 0.05) by including increasing concentrations of phytase to the NC diet. In Exp. 2, experimental procedures were similar to those used in Exp. 1. Forty-eight pigs (initial BW: 11.15 ± 0.85 kg) were randomly allotted to 6 dietary treatments in a 28-d experiment. Treatments included a PC diet, an NC diet, and 4 diets in which 500 or 1,000 FTU/kg of either the corn-expressed phytase or a commercial microbial phytase were added to the NC diet. Pigs fed the NC diet had reduced (P < 0.01) final BW, ADG, G:F, and bone ash concentrations compared with pigs fed the PC diet. When 500 FTU/kg phytase was fed, no differences were observed in growth performance or bone ash measurements between phytase sources, and there were no differences in growth performance among pigs fed 1,000 FTU/kg of either phytase source or the PC diet. However, regardless of concentration or source of phytase, pigs fed the PC diet had greater (P < 0.001) amount of bone ash, bone Ca, and bone P compared with pigs fed phytase diets. In conclusion, the corn-expressed phytase is effective in improving growth performance, Ca and P digestibility, and bone measurements in pigs fed diets that are deficient in Ca and P.

Abstract Two experiments were conducted to determine the effects of myo-inositol and phytase on growth performance, plasma metabolites, and nutrient digestibility of growing pigs. In experiment 1, 96 growing pigs with average initial body weight (BW) of 26.2 kg were used in a 25-d growth performance study. Pigs were assigned to four dietary treatments with three pigs per pen and eight replicate pens per treatment in a randomized complete block design. The four treatments were control diet (CD); CD + 2 g/kg inositol; CD + 1,000 FYT/kg phytase and CD + 3,000 FYT/kg phytase. Pigs were weighed individually every week. On day 25, blood sample was collected from one pig per pen to measure plasma metabolites concentrations. In experiment 2, 16 barrows (initial BW 34.8 ± 8.2 kg) were surgically fitted with T-cannulas. Pigs were allotted to four blocks based on BW and assigned to a quadruplicate 4 × 2 incomplete Latin square design with same four dietary treatments and two periods. Ileal digesta samples were collected from each pig on days 6 and 7 of each period to determine apparent ileal digestibility (AID) of nutrients. Phytase supplementation increased final BW and average daily gain (ADG) compared with CD (P < 0.05) with no effects on average daily feed intake (ADFI) and gain to feed (G:F) was higher in 3,000 FYT/kg phytase (P < 0.05). Inositol supplementation had no effects on growth performance. Plasma myo-inositol concentration was increased by inositol supplementation, and 3,000 FYT/kg phytase increased myo-inositol in the plasma by 97.2% (P < 0.05). Plasma P concentration was increased by 1,000 or 3,000 FYT/kg phytase with no effects on alkaline phosphatase (ALP), glucose, triglycerides (TAG), calcium (Ca), and urea concentrations. Phytase supplementation reduced (P < 0.05) the phytate-P concentration in the ileal digesta and increased the digestibility of phytate-P and total P with no effects on the AID of dry matter (DM), gross energy (GE), nitrogen (N), and Ca. In conclusion, the beneficial effects of 3,000 FYT/kg phytase on feed efficiency may due to the increased release of both myo-inositol and phosphorus (P), and may not be solely due to myo-inositol release by this level of phytase.

A sixteen week trial was conducted to assess the effect of replacing cassava grit supplemented with Moringa leaf meal (MLM) for maize on the nutrient retention, haematology and serum biochemistry of 120 “day old” Harco cockerel chickens. Four experimental cockerel starter and finisher diets were formulated with diet 1 formulated to contain 0% cassava grit while diet 2, 3 and 4 were formulated to contain cassava grit at 33.3, 66.6 and 100% replacement for maize with 5% of moringa leaf meal inclusion in diets 2, 3 and 4 respectively. Chicks were randomly assigned to the four treatment diets in a completely randomized designed (CRD). Result on nutrient digestibility show that crude fibre was significantly (P<0.05) affected by the treatment diets with highest values of 68.21 recorded in birds fed diet 4. Ash and NFE were significantly (P<0.05) influenced by the treatment diets with highest mean values (50.81 and 55.15) observed in birds placed on 100% CGM. Haematological indices revealed that Packed Cell Volume was significantly (P<0.05) highest 32.17% among birds fed the control diet. However, neutrophil was significantly (P<0.05) affected by the treatment diets with highest value 17.67% recorded in birds fed the control diet. Serological study revealed that Albumin value was significantly (P<0.05) influenced by the dietary treatments with highest value (1.60mg/dl) recorded among birds fed 33.3% CGM based diet. Therefore, Cassava grit can replace maize up to 66.6% inclusion level with 5% appropriate supplementation with moringa leaf meal in cockerel diet for optimum nutrient utilization and blood quality.

The nutritive value ,voluntary dry matter intake, and the nutrient digestibility of graded levels of Gmelina arborea and cassava peels concentrates in WAD sheep was investigated. Twelve WAD sheep aged 1-2 years old and weighting 14.00± 0.45 kg were used in a complete randomized design. Diets were formulated such that cassava peels was replaced with Gmelina arborea leaf meal at 0, 33.33, 66.67, 100% levels, designated as diets A, B, C, and D respectively. Diet without Gmelina arborea leaf meal was tagged the control diet. The concentrate feed was compounded to contain 16% CP. Diets with 33.33% inclusion level of Gmelina arborea had significantly (P<0.05) higher dry matter intake (DMI) 598.80g day-1, while the lowest DMI 425.00g day-1 was obtained in animals fed 100% inclusion level of Gmelina arborea. Crude protein intake (CPI) of animals fed diets with 33.33% inclusion levels of Gmelina arborea were significantly (P<0.05) highest, followed by 66.67% inclusion level and the least was observed in 0% inclusion level of Gmelina arborea. Dry matter digestibility (DMD) was significantly (P<0.05) different across the dietary treatments, animals placed on diets with 33.33% inclusion level had the highest DMD, followed by animals on diets with 66.67, 100 and 0% inclusion levels. CP digestibility (P<0.05) increased from 33.33% to 100% inclusion levels of Gmelina arborea leaf meal, the lowest CP digestibility was observed at 0% inclusion level. CF digestibility (P<0.05) increased from 33.33% to 100% inclusion levels of Gmelina arborea leaf meal, while the lowest CF digestibility was observed at 0% inclusion level. N intake increased significantly (P<0.05) with increase in the level of Gmelina arborea inclusion from 33.33% to 100%. N retention was significantly (P<0.05) different, diets with 33.33% Gmelina arborea inclusion had the highest value (64.36g day-1) followed by 66.67%, 100% and the least (52.64g day-1) was at 0% inclusion level of Gmelina arborea.  N balance values also followed the same trend. From the results of this study, it can be concluded that the inclusion of Gmelina arborea leaf meal in WAD rams diet was well tolerated without adverse effect on acceptability, intake and nutrient digestibility, and inclusion level of 33.33% is hereby recommended in ruminants diet for optimum performance and productivity.

Intestinal Digestibility

AbstractThe aim of this study was to determine whether dietary supplementation with zinc oxide nanoparticales (NP-ZnO) as a substitute for the conventional ZnO affects the intestinal digestibility of selected minerals, growth performance and meat quality in turkeys. The replacement of ZnO with NP-ZnO had no effect on the intestinal digestibility of Zn, Cu, Fe and Ca, whereas the lowest dose of supplemental Zn reduced Zn digestibility. The applied inclusion levels and sources of Zn had no effect on the growth performance (except the feed intake) of turkeys, including liveability. No differences in the relative weights of the heart, spleen and bursa of Fabricius (except the liver), or the weights of the femur and tibia were found between the dietary treatments. Neither the dose nor the source of supplemental Zn influenced carcass dressing percentage or the share of breast, thigh and drumstick muscles in the carcass. In comparison with the highest and moderate doses of Zn, the lowest inclusion level of Zn contributed to increased yellowness of breast meat (P=0.005). The analyzed doses and sources of supplemental Zn exerted varied effects on the redox status of fresh and frozen breast meat. In conclusion, the growth performance of turkeys, carcass yield and composition as well as the redox status of fresh and frozen breast meat were generally similar, regardless of the dietary source and level of Zn. The beneficial effect of Zn addition at 100 mg/kg was improved Zn and Ca digestibility, and increased redness of breast meat.

The objective of this present study was to investigate the effect of feeding fermented mixture of papaya leaf and seed meal (FERM) on the physical and chemical characteristics of meats of the Indonesian indigenous crossbred chicken (IICC). The study was carried out with 300 day-old IICC. The chicks were randomly distributed to five treatment groups, i.e., CONT (control diet based on corn-soybean- diet), FERMA (diet containing 1% FERM), FERMB (2.5% FERM), FERMC (5% FERM) and FERMD (7.5% FERM). Each treatment group consisted of 6 replicates with 10 IICC in each. At week 8, one chick from each replicate was randomly taken and slaughtered. After being de-feathered and eviscerated, samples from breast and thigh meats were obtained. Results showed that the increased levels of FERM was followed by the increased (P<0.05) pH values, moisture and crude protein content of breast meats of the IICC. Dietary incorporation of FERM especially at the level of 2.5% increased (P<0.05) the content of fat in the breast meat of IICC, while further increased levels of FERM did not alter (P>0.05) the fat content of the IICC breast meat. Dietary treatment did not have any effect (P>0.05) on the lightness (L*) values of breast meat of the IICC. The redness (a*) values were higher (P<0.05) in FERMD breast meat than other. FERM diet resulted in lower (P<0.05) yellowness (b*) values in the IICC breast meat. The pH values and moisture content of thigh meat increased (P<0.05) with the increased level of FERM. The WHC decreased (P<0.05) with the elevated levels of FERM in the diets. There was an increase (P<0.05) in crude protein concentration in FERMA as compared to the other meats. Crude fat and ash concentrations in thigh meat were affected (P<0.05) by the treatments. Dietary treatments had no impact (P>0.05) on L* values of thigh meats. Feeding FERM at 7.5% from diets increased (P<0.05) and decreased (P<0.05) the redness and yellowness of meats. In conclusion, dietary inclusion of FERM especially at the level of 7.5% from diets improved the physical and chemical characteristics of the IICC meats.
