Two experiments were conducted to examine the effect of liquid to feed ratio, steeping time, and enzyme supplementation on performance of weaner pigs. In Expt 1, 40 male weaner pigs (weaned at 27 days of age) were randomly allocated to 4 treatments, including a dry control and 3 liquid diets of differing liquid: feed ratios (2 : 1, 3 : 1, and 4 : 1). Pigs were fed individually. Bodyweight was measured weekly and feed intake measured daily. The results confirmed the advantage of liquid feeding but indicated that liquid: feed ratio had very little effect on performance of weaner pigs. Whereas the digestible energy (DE) content of the 2 : 1 and 3 : 1 diets was similar to the control diet, the DE content of the 4 : 1 diet was significantly lower, possibly due to the removal of the insoluble marker (long chain hydrocarbon) by the amount of water in the diet.In Expt 2, the effect of a xylanase and steeping time on pig performance was assessed in a 2 × 2 factorial design (2 steeping times, 1 h v. 15 h; enzyme addition, + v. –). Sixty male weaner pigs (weaned at 27 days of age) were randomly allocated to 4 treatments and fed individually for 3 weeks. Bodyweight was measured weekly and feed intake measured daily. The experiment revealed that both steeping and enzyme addition increased feed intake (P�<�0.01) and growth rate (P < 0.05), suggesting that both techniques influence the non-starch polysaccharide composition of the wheat-based diet. Feed conversion ratio (FCR) tended to be improved more by steeping than by enzyme addition (P = 0.06). The results would suggest that steeping improves FCR by allowing increased hydration of feed and subsequent activation of the endogenous enzymes present naturally in grains.The present study was designed to test the hypothesis that the water: solid feed ratio would affect nutrient availability to weaner pigs fed liquid diets.

Seventy-two individually housed, entire male (Large White × Landrace) weaner pigs (28 days; 7.4 ± 0.4 kg) were used in a 26-day feeding trial. The pigs were allocated to one of six treatments in a 3 by 2 factorial design. The factors were (1) steeping duration of liquid feed [0 (dry control diet), 1 or 24 h], and (2) enzyme supplementation (0 or 300 ppm xylanase). The basal diet was wheat-based (65%) and was formulated to be marginally adequate for pigs of this age, containing 14.5 MJ digestible energy (DE)/kg and 0.85 g available lysine/MJ DE. Feeding pigs liquid diets steeped for 1 h increased feed intake (61 g/day; s.e.d. 17; P < 0.05) and daily gain (70 g/day; s.e.d. 17; P < 0.05) and improved feed conversion ratio (1.16 versus 1.22; s.e.d. 0.03; P < 0.05) compared with pigs fed dry diets. Performance was not further improved by steeping for 24 h. The addition of xylanase to the diets had no positive effect on any of the performance measures and was associated with a significant (40 g/day; s.e.d. 14; P < 0.05) reduction in feed intake. These results provide no support for supplementing liquid diets for weaner pig diets with xylanase.

The viability of including millrun (a byproduct of wheat milling) in diets for weaned pigs was assessed in two 26-day feeding experiments, the first using 48 and the second 128 individually housed, entire male pigs (Large White × Landrace) weaned at 28 days (average weight 7.4 kg). In Experiment 1, millrun included in iso-energy, iso-lysine diets at 0, 12.5, 25, 37.5, and 50% had no effect on performance or digestibility. Therefore, in Experiment 2, pigs received diets containing 50% millrun in a 2 × 4 factorial design. The two factors were: (1) feed form (dry or liquid) and (2) enzyme supplementation (0 or 300 μg/g of a xylanase primarily targeting soluble non-starch polysaccharide (sNSP), 400 μg/g of a xylanase targeting only insoluble NSP, or both xylanases. The inclusion of NSP-degrading enzymes had no significant effect on pig performance or diet digestibility. Feed conversion ratio (FCR) was improved by 0.10 ± 0.02 in liquid-fed pigs (P < 0.05). Apparent digestible energy and faecal gross energy (GE) digestibility were not affected by treatment, but ileal GE and crude protein (CP) digestibility were, respectively, 9.0 ± 3.4 and 2.5 ± 0.65 percentage units higher in pigs fed liquid diets (P < 0.05). Dietary treatment significantly affected the concentrations of sugar, starch, total NSP, and sNSP in digesta from different segments of the gut, without affecting pig performance. In conclusion, weaner pigs can be fed appropriately formulated diets containing 50% millrun without loss of performance. The FCR and CP digestibility were improved by liquid feeding, but not by the addition of NSP-degrading enzymes.

One hundred and forty-four individually housed, entire male (Large White × Landrace) weaner pigs (28 days; 7.3 s.d. 0.1 kg) were individually housed and allocated to a 26-day feeding trial of 2 by 2 by 3 factorial design. The factors were (1) feed processing method (meal or steam pelleted), (2) feed form (dry or liquid), and (3) enzyme addition (basal diet, or basal diet plus 300 ppm xylanase or 100 ppm phytase). Five days post weaning, two pigs were removed from each treatment. The basal diet was formulated to be marginally adequate for pigs of this age, providing 13.8 MJ digestible energy (DE)/kg DM and 0.79 g available lysine/MJ DE. The diet contained 0.81% Ca, 0.44% non-phytate-P and 0.31% phytate-P. Compared with pigs fed dry diets, pigs fed liquid diets consumed less feed (70 ± 14.2 g/day; P < 0.05) had a lower daily gain (49 ± 12.5 g/day; P < 0.05) and as a consequence had a lower 26-day weight (1.1 ± 0.4 kg; P < 0.05). However, pigs fed liquid diets had a better feed conversion efficiency (adjusted to the same DM content as dry feed) than pigs on dry diets (1.16 versus 1.20 ± 0.02; P < 0.05). Steam pelleting the diets had no effect on feed intake or daily gain, but did improve feed conversion ratio (1.14 versus 1.22 ± 0.02; P < 0.05). The poorer growth on liquid feeds appeared to result from the feeding method imposing a degree of restriction on feed intake. Xylanase or phytase supplementation did not significantly affect non-starch polysaccharide levels in the diets or growth performance. Phytase supplementation increased (P < 0.05) daily intake, daily gain and 26-day weight, of pigs fed dry diets, but not those fed liquid diets. The results indicated that when diets were fed in liquid form, prior steam pelleting of the diets and enzyme supplementation did not provide additional benefit.

Poultry diets are largely composed of plant based materials that hold non-starch polysaccharides (NSP). The inclusion of NSP rich ingredients often reduces feed cost, but hampers a proper digestion due to anti-nutritional factors (ANF). Against this background, potency of exogenous enzymes was evaluated to upgrade dietary energy and total protein. A total of 180 broiler chickens were used in 28 days feeding trial. Six experimental diets were formulated in which maize based diet served as control (T1). Maize in the control diet was replaced by sorghum at the levels of 20% (T2), 40% (T3), 60% (T4), 80% (T5), and 100% (T6), respectively. Besides the control diet every other dietary groups were supplemented with enzyme at the rate of 50g/100kg. The broiler chicks were weighed and allotted to six dietary treatments of 30 birds each. The groups were replicated three times with 10 birds per replicate. The parameters determined for growth performance include: Final weight (g), Weight gain (g/bird), Daily weight gain (g/bird), Feed intake (g/bird), Daily feed intake (g/bird) and Feed conversion ratio (FCR). The result showed significant (p<0.05) effect on total feed intake and daily feed intake. Final weight, daily weight gain and feed conversion ratio (FCR) were not significantly (p>0.05) influenced by dietary treatments. Birds fed 60% (T4), 80% (T5) and 100% sorghum (T6) with enzyme supplementation showed higher similar statistical values 1365.00g, 1373.33g and 1373.66g, respectively for total feed intake. Haematological parameters were not significantly (p>0.05) affected by dietary treatments. Maize-sorghum based diet with enzyme supplementation had significant (p<0.05) effect on total protein, albumin and uric acid. Birds fed diets with 80% (T5) and 100% T6 sorghum levels with enzyme supplementation showed higher (p<0.05) statistical values 4.10 and 3.66 g/dl for total protein. Inclusion of sorghum up to 100% replacement level for maize with enzyme supplementation could be fed to starter broiler chicks for improved growth performance without adverse effect.

ABSTRACT   EFFECT OF UTILIZATION OF VIRGIN COCONUT OIL (VCO) IN THE DIET ON PIG PERFORMANCE. Utilization of fats and oils in pig diets is of great importance due to their high energy value. VCO is obtained by cold press processing of the kernel from the coconut fruit. Utilization of virgin coconut oil (VCO) in the diets on pig performance.  The present study was designed to elaborate the effect of utilization of VCO in the diets on energy and protein digestibility of growing pigs. The experiment was conducted using 20 castrated male pigs aged 1.5 - 2.0 months weighing 12,0±2,0 kg. The data were analyzed according to the linear model procedure for ANOVA appropriate for Randomized Block Design with 5 treatments and 4 replications. Treatments were formulated as follow: R0 = 100% control diet + 0% VCO; R1 = 99.5% control diet + 1.0% VCO; R2 = 98.0% control diet + 2.0% VCO; R3 = 97.0% control diet + 3.0% VCO; and R4 = 96.0% control diet + 4.0% VCO. Parameters measured were: daily feed intake, daily gain, daily water consumption. The results showed that the utilization of VCO up to 4% in the diets had no significant effect (P > 0.05) on daily feed intake, daily gain, daily water consumption of pigs. It can be concluded that the addition of VCO up to 4.0% in the diets has no significant meaning on pig performance.   Key words: Virgin coconut oil (VCO), Performance, Growing pigs

The effects of wet feeding and a multi-enzyme preparation on the nutritional value of wheat screenings (WS) for broiler chicks were investigated. In total, 540 1-day-old Ross-308 broiler chicks were fed a corn–soybean meal-based diet up to 29 days of age. At that time, the birds were randomly assigned to nine diets in a completely randomised design with a 3 × 3 factorial arrangement, including three levels of WS (0%, 25% and 50%, WS0, WS25 and WS50 respectively) and three processing methods (no processing, enzyme supplementation and wet feeding). The enzyme mixture contained endo-1, 4-β-xylanase (200 FXU/g), endo-1, 4-β-glucanase (50 FBG/g), endo-1, 8-β-glucanase (21 FBG/g), hemicellulase (3000 VHCU/g), α-galactosidase (3 GALU/g) and protease (260 U/g) and was supplemented at a level of 6 g/kg of diet. The inclusion of water in wet diets was in the extent of 1.2 kg/kg of diet. During the period from 29 to 49 days of age, feed intake was not affected (P > 0.05) by the inclusion of WS in the diet, whereas chicks fed the WS25 diet had a higher (P < 0.05) bodyweight gain than did those on WS0 diet. The feed conversion ratio (FCR) was improved (P < 0.05) by the inclusion of WS in the diet throughout the study. The feed intake was increased (P < 0.05) by enzyme supplementation to WS50 diet, while bodyweight gain was increased (P < 0.05) by wet feeding. Enzyme supplementation did not affect (P > 0.05) FCR, whereas wet feeding resulted in lower (P < 0.05) FCR over the entire study. The plasma concentration of glucose was increased (P < 0.05) by the inclusion of WS in the diet. The viscosity of the ileal digesta was higher (P < 0.05) in chicks receiving the WS50 diet than that in chicks receiving the other diets. The jejunal villus height was increased (P < 0.05) and the jejunal crypt depth was decreased (P < 0.05) by the inclusion of WS in diet. The jejunal crypt depth was greater (P < 0.05) in chicks receiving the wet diets than in chicks receiving the enzyme-supplemented diets (P > 0.05). In conclusion, the results from the present study indicated that broiler growth performance was improved by the inclusion of WS in the diet and also by wet feeding. These effects were largely compatible with the changes that occurred in the small intestine morphology, but not with those observed for ileal digesta viscosity.

Digestive capacity of early-weaned pigs may be insufficient to fully digest many ingredients currently used in weaner diets. The aim of this experiment was to determine whether an exogenous enzyme preparation with broad carbohydrase activity could benefit pigs that developmentally might be immature at weaning, especially with regard to gastrointestinal development. Eighty Large White × Landrace pigs were used in a 2 × 2 × 2 × 2 factorial experiment with the factors being: weaning age (14 or 24 days), weaning weight (heavy or light), sex (boar or gilt), and dietary Biofeed Plus CT (0 or 500 μg/g) which contained fungal xylanases, pentosanases and β-glucanases. Pigs were housed individually and given a wheat-based (550 g/kg) diet containing 15.0 MJ DE and 15.9 g lysine/kg on an ad libitum basis for 21 days. The diet also contained 50 g/kg of soybean meal and 50 g/kg of lupin (Lupinus�angustifolius) kernels. The liveweights of heavy (H) pigs weaned at 24 or 14 days and light pigs (L) weaned at 24 or 14 days were 7.9 and 5.3 and 5.2 and 3.9 kg, respectively. Pigs weaned at 14 days grew slower (157 v. 345 g/day) than those weaned at 24 days, although there was a suggestion of an interaction between age and weight at weaning (P = 0.081). Thus, H and L pigs weaned at 14 days grew at 148 and 166 g/day, whereas H and L pigs weaned at 24 days grew at 374 and 315 g/day, respectively. Although there was no main effect of enzymes on daily gain (248 v. 254 g/day, P = 0.80), feed intake (278 v. 284 g/day, P = 0.79), or feed conversion ratio (1.19 v. 1.25, P�=�0.35), there were interactions with weaning age on daily gain (P = 0.050) and feed intake (P = 0.060). Pigs weaned at 14 days grew slower (176 v. 138 g/day) and ate less (206 v. 174 g/day), whereas pigs weaned at 24 days grew faster (321 v. 369 g/day) and ate more (351 v. 394 g/day), when supplemented with enzymes. During the third week after weaning there were interactions between dietary enzymes and sex (P = 0.060) and dietary enzymes and age (P = 0.023) on daily gain. Thus, pigs weaned at 24 days and supplemented with Biofeed Plus CT grew more quickly during the third week (559 v. 460 g/day), whereas the converse was true for pigs weaned at 14 days (286 v. 334 g/day). Also, enzyme-supplemented boars grew better over this period (457 v. 371 g/day), whereas the converse was true for gilts (388 v. 423 g/day). In conclusion, these data clearly indicate that the greatest determinant of post-weaning performance under the present conditions was the age of the pigs at weaning. Dietary enzyme supplementation appeared most efficacious in boars weaned at an older age, although benefits did not become apparent until 2 weeks after weaning.

Deficit of conventional feed resources in meeting increased demand has led to hike in their prices culminating in soaring cost of livestock feed. This has necessitated the search for cheap and easily available alternatives. Pride of barbados seed which constitute a waste has potential of becoming a cheap and easily available feed resource. Performance and nutrient digestibility of dietary inclusion of raw pride of barbados seed meal was evaluated in an eight week feeding trial. Atotal of sixteen crossbred (Large White x Landrace) weaned pigs of eight weeks of age were weighed and allotted to four dietary treatments with four pigs each being a replicate in a completely randomized design. Diet 1 (control) was without raw pride of barbados seed meal while 5%, 10% and 15% of virgin raw pride of barbados were included in diets 2,3 and 4 respectively. Weekly weight gain, daily feed intake, feed conversion ratio and nutrient digestibility of raw pride of barbados seed meal was also determined. Results revealed a significant average final body weight of 16.75kg (diet 3) to 24.50kg (diet 4).The pigs fed 15% raw pride of barbados had the highest feed intake of 137.20kg in diet 4 while the lowest feed intake was obtained in pigs fed 10% (diet 3) inclusion level of raw pride of barbados. Pigs maintained on the control diet had the best feed conversion (7.60kg) while the pigs fed diet 3 had the lowest feed conversion ratio (8.93kg). Crude protein, ether extract and dry matter digestibility was highest at T4 (84.15%, 80.21% and 86.70%) respectively while the least values (68.71%, 65.75% and 71.10% was obtained in T2 and T3 respectively. This study concluded that 15% inclusion of raw pride of barbados in the diets of crossbred weaned pigs had no deleterious effect on performance and nutrient digestibility of pigs.

Abstract Marine macroalgal derivatives such as laminarin have been considered as potential bioactive compounds in swine nutrition to improve post-weaning pig performance. However, a comprehensive understanding of the impact of these extracts on the intestinal microbiome and its subsequent influence on performance is not well characterized. Therefore, the objective of this study was to evaluate the effects of supplementing the diet of newly weaned pigs with laminarin, on animal performance and the intestinal microbiota using 16S rRNA gene sequencing. At 28 days of age, newly weaned pigs (n = 54) were assigned to one of two dietary groups: 1) basal diet and 2) basal diet + 300 ppm laminarin for a 14-day period. On day 15, nine pigs per treatment (one from each pen) were humanely euthanized and high-throughput sequencing of the V3-V4 hypervariable region of the bacterial 16S rRNA gene was performed on the Illumina MiSeq. Pigs fed the laminarin-supplemented diet had increased average daily feed intake, growth rate and body weight compared to pigs fed the control diet (P &lt; 0.05). Pigs fed the laminarin supplemented diet had reduced abundances of Enterobacteriaceae (P &lt; 0.05) compared to pigs fed the control diet. Enterobacteriaceae and Helicobacteraceae had negative relationships with average daily feed intake (ADFI), average daily gain (ADG) and butyric acid concentrations. In contrast, the beneficial Prevotellaceae were positively correlated with ADFI, ADG, total VFA, acetic, propionic, butyric and negatively correlated with isovaleric acid. Hence, supplementation with laminarin may accelerate the adoption of pigs to a post-weaning diet by promoting the proliferation of bacterial species that favourably enhance nutrient digestion and reduce the load of pathogenic bacteria impacting pig performance.

There is a well-established relationship between particle size of processed grains in diets and pig performance. It has been reported that as the particle size of feed is reduced there is an increase in the performance of pigs (Wondra et al., 1995). Increasing the surface area of feed ingredients by reducing particle size facilitates greater enzyme activity. Liquid feed provides an excellent medium for endogenous enzyme activation and the opportunity to improve the availability of nutrients (Brooks et al., 1996). The current study investigated the effect of particle size, processing and feed form on pig performance.
