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.

Weaner Pigs

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.

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.

Final Body Weight

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.

The Impact

An experiment was conducted to determine the impact of Plantain (PL), Bio-Sel-E and commercial broiler diet on the growth performance, feed conversion ratio, performance index and carcass yield of broiler. A total of 160 day old broiler chicks (Cobb-500) were randomly distributed into four groups with four replication in each group and having 10 birds in each replication. Basal diet was used for group 1 (control), Basal diet was supplemented with PL (0.5% of DM basis) and Bio-Sel-E (5g/50 birds in drinking water) for group 2 and 3 respectively and for group 4 used commercial broiler diet (Quality Feed Ltd.). Total feed intake was similar among the groups. Feed conversion ratios of PL diet, Bio-Sel-E diet, and commercial broiler diet were comparable, and were lower (P<0.05) than the control diet. Significantly higher body weight gain and performance index were found in PL, Bio-Sel-E and commercial broiler diet groups than control diet. The dressing yield of PL diet and commercial broiler diet were comparable, and they were higher (P<0.05) than Control diet and Bio-Sel-E diet. It could be concluded that the Supplementation of 0.5% PL in the diet had positive effect on growth, feed intake, feed conversion ratio, performance index and carcass characteristics of broilers almost similar of Bio-Sel-E and commercial broiler diet.

This study compared the feed intake and performance of Yankasa sheep fed Congo grass (Brachiaria ruziziensis) basal diet with different protein supplements of Cotton Seed Cake (CSC), PalmKernel Cake (PKC), Brewer'sDriedGrain (BDG) and sole B. ruziziensis grass (control). Sixteen (16) Yankasa sheep weighing between 21.63 and 22.23kg and aged about 12 months were randomly allotted to treatment diets. The total dry matter and crude protein intake were highest (P<0.05) in sheep on CSC supplement (996.33 and 118.56g) while the control diet had the least feed intake (796.4 and 57.90g).The total live weight gain (TLWG) increased (P<0.05) from 0.91kg in sheep fed Congo grass solely (control) to 2.50kg in those fed Cotton Seed Cake, while feed conversion ratio reduced from 52.50 in Congo grass to 29.15 inCSC treatment. It is concluded from this experiment that Yankasa sheep utilizedCSC better thanPKC,BDGandBrachiaria ruziziensis (control). It is therefore recommended that Brachiaria ruziziensis should be supplemented withCotton SeedCake at a rate of 250g/d for better intake and liveweight in Yankasa sheep production.

ABSTRACTIn an experiment which showed that the results of a genotype comparison are influenced by the design of the test, 16 castrated male and 16 female pigs of each of Large White (LW) and Gloucester Old Spot (GOS) breeds were allocated equally among four treat- ments: WW—rationed by weight and slaughtered by weight; A A—rationed by age and slaughtered by age; AW—rationed by age and slaughtered by weight; and WF—rationed by weight and slaughtered after a common total feed intake. The experiment was designed so that performance of LW would be similar on all treatments, and the degree to which the GOS differed from the LW on each of these treatments was then evaluated. All pigs started on the experiment at 12 weeks of age, at which time mean weight of the LW was 14% greater than the mean for the GOS. The only between- breed difference that was statistically significant (P<0·05) on all treatments was weight of lean. Average daily gain and efficiency of feed conversion were significantly different between breeds only on the WW treatment. Weight of fat was significantly different on WW and AW but not on AA or WF.

The effect of increasing the energy concentration of growing-finishing pig diets through inclusion of lard on performance, carcass and meat composition and lipid susceptibility to peroxidation was studied. A total of 720 Landrace × Large White male and female pigs (equal number of entire males and females) were used. Experimental diets were formulated to have a low (3000 kcal ME kg−1) or high (3200 kcal ME kg−1) energy level, but in all cases to have a constant lysine:ME ratio. This was achieved using a low (6.8 g kg−1) and a high (49.3 g kg−1) level of dietary lard inclusion. Gilts had lower daily gain (P < 0.0001) and worse feed conversion efficiency (P < 0.0001) than entire males. Susceptibility to oxidation was not affected by sex. Fat concentration in pig diets equilibrated in metabolizable energy and protein did not modify average gain, but reduced feed intake (P < 0.02), improved the gain:feed ratio (P < 0.0001), increased dressing percentage (P < 0.02) and produced higher carcass weight (P < 0.01). Carcass backfat and lean percentage were not affected by dietary treatment. A reduction in the proportion of (n-3) fatty acids in phospholipids (P < 0.03), a higher (n-6):(n-3) ratio (P < 0.01) and a lower susceptibility of muscle homogenates to oxidation was found in animals receiving higher levels of dietary lard (P < 0.01).

Sixty entire male pigs (Large White × Landrace × Duroc crossbred) were individually reared from 45 to 114 kg liveweight in a 2 by 3 factorial experiment to determine the interactive effects of sex (entire male pigs v. male pigs immunologically castrated using Improvac with vaccinations administered at 13 weeks of age and 5 weeks before slaughter) and a ractopamine feeding program (constantly fed 0 or 5 ppm ractopamine for 26 days before slaughter v. a step-up program where 5 ppm of ractopamine was fed for 14 days followed by 10 ppm ractopamine for the final 12 days before slaughter) on growth performance, carcass composition and pork quality. Following the second vaccination, immunocastrated pigs ate more (P < 0.001) and grew faster (P < 0.05) than entire male pigs without affecting feed conversion efficiency. Dietary ractopamine supplementation for the last 26 days before slaughter improved feed conversion ratio (P = 0.024) and daily gain (P = 0.046). Dietary ractopamine supplementation also increased carcass total tissue (P = 0.023) and total lean (P = 0.027) content without affecting the objective meat quality (P > 0.05) in both entire and immunocastrated male pigs. The effects of dietary ractopamine and immunocastration were additive, such that pigs that were immunocastrated and received ractopamine grew 18% faster than control entire males. However, a step-up program of ractopamine supplementation did not provide further improvements in growth performance and carcass composition when compared with constant 5 ppm ractopamine supplementation. These findings indicate that ractopamine supplementation improved growth performance in entire and immunocastrated male pigs, thereby offering a means of improving growth performance of entire males without detrimental effects on pork quality.

Sustained Increase

Porcine somatotropin (pST) treatment of pigs consistently improves daily gain and feed conversion ratio but the daily injections involved can be problematic. The sulfhydryl compound cysteamine hydrochloride (CSH) increases somatotropin secretion in several species, possibly through inhibition of somatostatin secretion. Therefore, it is possible that dietary CSH supplementation may provide a dietary means of increasing pST secretion and improving growth performance in finisher pigs. Eighteen female crossbred (Large white × Landrace) gilts (59.2 kg) were allocated to one of three treatments with the respective factors being a control diet, dietary CSH (0.7 g/kg) and intramuscular pST (5 mg/day) for 5 weeks. After slaughter the whole half carcass was cut into primal cuts which were then dissected to a retail level into lean, fat, bone and rind. Over the first 2 weeks of the study daily gain was increased by both pST (+46%, P < 0.001) and CSH (+12%, P < 0.05) while feed conversion ratio was decreased by pST (–30%, P < 0.001) and CSH (–9.4%, P = 0.08) over this period. Over the entire 5 weeks there was a large and sustained increase in daily gain in pigs treated with pST (+38%, P < 0.001), while dietary CSH tended to cause a more modest increase in daily gain (+7.4%, P = 0.06). As a result, final liveweight (+10.6 and +2.0 kg, respectively) and carcass weight (+5.8 and +1.6 kg, respectively) were increased by pST and CSH. Back fat was decreased by both pST and CSH (–1.7 and 1.0 mm, respectively). Total dissectible tissue was increased by pST (+9.1%, P < 0.001) and CSH (+3.3%, P < 0.05). In pigs treated with pST, the increased tissue was primarily as lean (+11.1%, P < 0.008) and bone (+17.8%, P = 0.017), whereas an accumulation of non significant increases in lean, rind and bone was responsible for the increased dissectible tissue in the carcass of pigs supplemented with CSH. In conclusion, dietary CSH increased daily gain and carcass weight and decreased FCR and P2 backfat, with responses being most pronounced over the first 2 weeks of dietary supplementation and not as great as those caused by exogenous pST treatment.

Rifat M, Subagyo YBP, Pratitis W. 2008. Supplementation effect of temulawak (Curcuma xanthorrhiza) meal in ration on male local rabbit performance. Biofarmasi 6: 58-63. Rabbit was the alternative livestock which could be used to fulfill the increasing demand of animal protein. The meat of rabbit has smooth structure, shape and color as chicken meat, with protein which higher than cattle, sheep and pork, and also low cholesterol. To increase rabbit productivity, it could be reached by giving temulawak meal as additive feed which could stimulate stomach depletion and a passion to eat. This research aimed to determine the supplementation effect of temulawak meal (Curcuma xanthorrhiza Roxb) in ration on male local rabbit performance. It was held in Gulon village, Jebres district of Surakarta regency since November 28th, 2007 until January 8th, 2008. This research used 24 male local rabbits with average body weight 727.79±97.3 grams divided into four treatments and six replications, each replication consisted of a rabbit. The diets included rendeng (peanut tree) and concentrate with a ration of 70:30. The treatments were P0 (70% rendeng and 30% concentrate) as control diet, P1 (control diet + 2% temulawak meal), P2 (control diet + 4% temulawak meal), and P3 (control diet + 6% temulawak meal). Variable measured were feed intake, average daily gain, feed conversion ratio, and feed cost per gain. Data from the research result was analyzed with a variance analysis based on a completely randomized design with one-way classification. The results showed that the average of four treatments (P0, P1, P2 and P3) in series for feed intake were 51.89; 53.85; 50.02 and 55.57 (gram/head/day), average daily gain were 6.41; 6.21; 4.86 and 6.03 (gram/head/day), feed conversion ratio were 9.22; 8.83; 11.21 and 9.44, and feed cost per gain were Rp31.63; Rp32.18; Rp41.90 and Rp36.19. Variance analysis result was not significant (P≥0.05). Based on the results, it could be concluded that temulawak meal supplementation in ration did not effect on male local rabbit performance.
