One hundred and twenty-eight pigs were placed into four groups and each group was fed from approximately 32 to 97 kg liveweight one of four diets: a control corn-soy diet or one of three diets containing 30.0, 65.0 or 96.7% of Tibor naked oats. Total liveweight gains and carcass backfat and quality index values were not significantly different at the end of the 77-d growth period. Feed conversion of the oat diets was progressively improved as the amount of oats in the ration increased; probably because the energy content of the rations increased as the concentration of naked oat kernels with their 8–10% total lipid increased. Diets containing the higher levels of oats also produced a better carcass yield (or dressing percentage) than the control diet. Tibor naked oats are thus a suitable replacement for all or part of the grain corn and soybean meal in a grower-finisher pig ration. Key words: Pig, grower-finisher diets, naked oats, cultivar Tibor

The yolk lipid composition was determined and the sensory and internal quality evaluated for eggs obtained from hens at 8 and 15 m of age from two experiments. In exp. 1, in which naked oats replaced corn and soybean meal at levels of 0–800 g kg−1, there was a marked decrease in Roche yolk color at 8 mo, an increase in egg weight, and at 15 mo and a decrease in yolk flavor intensity with increasing level of oats. In exp. 2, there were four diets (0) a corn-soybean meal control, (876) a soybean-free naked oat alfalfa diet, (874) diet 876 supplemented with lysine and methionine and (691) diet 876 supplemented with canola meal. Haugh units were greater and yolk color less for supplemented naked oat diets versus the control diet. The yolk lipid content of sphingomyelin and sterols were higher than for the control diet. A yolk sulfury aroma was noted at 15 mo. At 8 mo, egg Haugh units were lower for the unsupplemented oat diet relative to the corn-soy diet. There were no other detrimental effects of oat diet on egg sensory quality. Other than a corrigible yolk color effect, egg quality traits do not limit the use of naked oats in poultry layer diets.

Two experiments were conducted with 640 and 480 White Leghorn strain-cross hens to determine the optimum level of inclusion of naked oats (Avena nuda L. 'Tibor') in diets fed for 51 wk. In exp. 1 oats from 2 crop years were substituted for corn and soybean meal at levels of 0, 300, 600 and 782 or 808 g kg−1 in isoenergetic and isolysinic diets. Egg yield (46.4 g d−1) and egg production (78.0% hen.day) were unchanged up to 600 g oats kg−1 but were 4 and 6% lower at the highest dietary levels due in part to a 4-d later sexual maturity. Egg weight was 2% greater in all oat diets than in the control diet. Feed utilized per gram egg was 4.7% lower at 600 g kg−1 than at 0 g oat kg−1 the other diets being intermediate. A difference between crop years was seen in a higher percent small grade eggs for 1985. Dietary treatments had no effect on feed utilized per egg laid, incidence of soft shell and cracked eggs or on final body weight. In exp. 2, naked oats with alfalfa meal and a vitamin-mineral premix were supplemented with canola meal or lysine plus methionine or not supplemented, to give dietary oat levels of 675, 874 and 876 g kg−1 for comparison with a control of 0 g kg−1. Supplementation with canola meal supported 3.5% higher egg yield and hen.day egg production than that with lysine plus methionine, whereas for both supplemented diets egg yield, hen.day percent egg production and egg weight, as indicated by distribution of eggs between size grades, were, respectively, 8, 6 and 1.7% greater and feed utilized per gram egg was 7% lower than for the supplemented naked oat diet. The corn-soy control diet differed from the amino-acid-supplemented diet only in a 4.9% greater feed utilization per gram egg. It was concluded that naked oats can replace corn and soybean meal in layer diets and that, with supplementation of canola meal or lysine plus methionine, oat levels up to, respectively, 675 and 874 g kg−1 diet can support satisfactory and efficient egg production.

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

The effect of fermentation of cassava tuber followed by its gelatinization was evaluated as a method of processing cassava for use as source of energy in broiler diets. Peeled and unpeeled cassava tubers were separately fermented in water for 4 days, dried in the sun and then milled to produce fermented peeled and unpeeled cassava tuber meals, respectively. The dusty meals were then gelatinized by mixing with water in pots seated over fire at the rate of 1kg of cassava tuber meal to one litre of water and stirred until they gelatinized into fufu. The gelatinized pastes were then taken bit by bit and flattened on polythene sheets and dried in the sun. The resultant fermented and gelatinized peeled and unpeeled cassava tuber cakes were then milled to produce fermented and gelatinized unpeeled cassava tuber meal (UFGC), a brownish-looking non-dusty product and fermented and gelatinized peeled cassava tuber meal (PFGC), an ash-looking non-dusty product. Three broiler diets were made such that diet 1 (control) contained maize as source of energy, while in diets 2 and 3, the maize in the control diet was completed replaced with UFGC and PFGC, respectively, both in the starter and finisher diets. One hundred and twenty (120) broiler chicks were divided into 3 groups of 40 birds each and each group assigned to one of the diets, using completely randomized design, and fed for 4 weeks with the starter diets and finisher diets for another 4 weeks. At the starter phase, the UFGC diets gained significantly (P < 0.05) less weight and consequently had poorer feed conversion ratio. There were no significant differences in feed intake (P < 0.05). At the finisher phase, the group on UFGC gained significantly (P < 0.05) more body weight. The groups on cassava diet tended to consume less feed and so had better feed conversion ratio. There were no differences (P > 0.05) in dressed weights and weights of internal organs but the group on PFGC diet accumulated significantly (P < 0.05) more abdominal fat.

The objective of this study was to evaluate the total replacement of soybean meal (SM) with extruded semi-whole soybean (ESWS) and its effects on feed digestibility, growth performance, plasma urea concentration (PUC) and economic feasibility. In Experiment I, a digestibility assay was undertaken using 12 crossbred pigs with an initial average body weight (IABW) of 18.85 ± 0.69 kg, distributed in a completely randomized design (CRD), with two treatments (reference diet and replacement of 30% of the reference diet by ESWS), six replicates and one pig per experimental unit. Experiment II involved 64 crossbred piglets, entire males, with an IABW of 7.46 ± 0.55 kg, distributed in a CRD, with two treatments (a control diet containing SM and another in which ESWS replaced SM), eight replicates and four animals per experimental unit. The digestible contents of dry matter, crude protein and gross energy of ESWS were 91.26%, 42.21% and 4,629 kcal kg -1, and the digestibility coefficients were 92.33%, 96.49% and 91.21%, respectively. Experiment II data indicated an effect on the feed conversion (FC) in the total period, in which pigs fed SM presented better FC. The diets affected the PUC in the pre-starter II phase and the total period, with pigs fed SM showing higher PUC. The cost of feed per kilogram of live weight gain increased in the starter phase. ESWS does not change the DWG and ADFI of piglets but worsens both the FC in the total period and economic results.

An experiment was conducted to evaluate the replacement value of poultry visceral offal meal (PVOM) substituting for fish meal (FM) on an equal protein basis in the diets of unsexed Ross-strain broiler chickens from day-old to 8 weeks of age. One hundred and fifty birds were allotted in groups of 10 into 15 equidimensional floor pens with floor space of 0.189m2 per bird. There were three replicates per treatment diet, with 10 birds per pen serving as a replicate. Five treatment diets, each for the starter and finisher phases of 5 and 3-week duration respectively were fed ad libitum. Diet A (control) contained 8% FM which was gradually replaced with PVOM at 2,3,4,6,6,90 and 9.20% in diets B, C, D and E respectively for both phases. All the diets were isocaloric (ca 12MJ   ME/kg) for both phases and isonitrogenous with 23 and 20% dietary crude protein contents for the starter and finisher diets respectively. Feed intake and feed conversion rations (FCR) were similar (P >0.05) on all diets in support of complete substitution. However , weight gain for 8 weeks on the control diet was better (P <0.05) than those on FM/PVOM- and PVOM-diets whose weight gains were similar (P < 0.05). The mean feed intake values of 4.031, 3.936, 3.760, 3.870 and 3.715 kg/bird were obtained for birds receiving diets A,B,C,D and E respectively while the equivalent FCRs were 2.326, 2.352, 2.233, 2.326 and 2.340. The mean weight gains for birds on diets A,B,C,D and E for 8weeks were 1.824, 1.688, 1.689, 1.676 and 1.590 kg/bird respectively. The dressed weight and weight of back, drumsticks, things and wings were similar (P >0.05) for all diets in favour of complete substitution of FM with PVOM. Mean dressing percentages were 58.24 to 69.07% . It is concluded that PVOM could replace FM completely in broiler diets.

Cassava Peel

The effect of two empirical methods of substituting maize with parboiled cassava peel meal (PCPM) in the diets of 168, 11-week old Isa Brown cockerels were examined in a 3-week experiment. The control diet A contained 40% maize while the proportion of maize in the control diet was replaced with PCPM at the graded levels of 20% of diets B and C, 30% of diets D and E and 40% of diets F and G with and without regard to the energy content of PCPM respectively. Consequently, diets A, B, D and F contained metabolisable energy (ME) content of about 2600s kcal/kg while diets C, E and G contained ME of about 2400, 2300 and 2200 kcal/kg respectively. The calculated crude protein (CP) contents of all diets were similar (17% CP). The results on the performance characteristics studied did not reveal any adverse effect of the two empirical methods of substitution of maize with PCPM in the diets of growing cockerels. The growth rate and feed conversion ration of birds fed on diets containing 50 and 75% of PCPM at the expense of maize using the two substitution methods were similar to those of the control birds. However, there was depression in feed intake at the replacement levels beyond 50%. Thus, it was concluded that the two substitution methods could be used to replace maize with PCPM at the level of 75% of the former without adverse effect on weight gain and feed conversion ratio in the growing cockerels during the early stage of growth.

Thirty-six boars and 36 barrows were fed four diets. The control was a fortified corn-soybean meal diet. Diets 50 L and 100 L were lysine-supplemented, and 48% and 95%, respectively, of the corn and soybean meal were replaced by Tibor naked oats. Diet 100 (unsupplemented) contained 95% naked oats. The diets were pelleted and given ad libitum to pigs housed three per pen. At a slaughter liveweight of approximately 90 kg, the left side of the carcass was used for carcass and meat quality examinations and samples were taken for fatty acid (FA) analysis. Additionally, 24 boars and 24 barrows were fed the four diets in a metabolism trial to determine metabolizable energy and nitrogen values. Daily gain by pigs fed Diet 100 was less (P < 0.01), and their times to market weight were 10 and 8 d longer, respectively, than pigs fed Diets 50 L and 100 L. Boars ate significantly less feed daily than barrows, and the rate of gain for boars was less and feed efficiency higher than for barrows. Total yield of lean meat was less (P < 0.05) from Diet 100 pigs than from those fed the other diets. The carcass index was higher (P < 0.05) for boars (106) than for barrows (102). The FA profile for the Tibor naked oats was very similar to that reported in a previous study even though the two crops were grown on different farms and 1 yr apart. Naked oats increased significantly the concentration of 18:1n–9 and 20:1 in the carcass backfat, but did not influence the quality of the loin muscle fat. An increased (P < 0.05) intensity of flavor in the pork loin roasts was associated with the naked oats diets. Boar roasts scored higher (P < 0.05) for juiciness than those from barrows; there was no difference in boar taint between the two sexes. The metabolizable energy value of the control diet was higher than those of the oats diets; significantly higher when corrected for N retained. Pigs fed Diet 100 L retained (P < 0.05) the most N (18.7 g d−1) and Diet 100 the least (15.8 g d−1). Nitrogen retention as a proportion of N intake was more (P < 0.05) for boars than for barrows. This study supported the inclusion of at least 48% naked oats in a diet for growing-finishing pigs. Key words: Boars, oats (naked), metabolism, carcass, fatty acids, meat quality

Eighty crossbred pigs (28.7 ± 3.9 kg BW) were assigned to one of five dietary treatments in a factorial design experiment (sex × treatment). The control diet was formulated using barley and soybean meal, while four experimental diets were formulated with either toasted or non-toasted canola meal replacing either half or all of the soybean meal in the test diets. The total glucosinolate content of the non-toasted meal was more than 15-fold higher than the to asted meal (1.01 vs. 15.58 µmol g-1). The principal glucosinolates in the non-toasted meal were 3-butenyl (3.05 µmol g-1), 2-OH-3-butenyl (5.47 µmol g-1) and 4-OH-3-methylindoyl (4.68 µmol g-1). Digestibility coefficients for dry matter, crude protein, and gross energy were significantly (P < 0.05) lower for the toasted and non-toasted canola meal diets compared with the soybean meal diet. There were no significant differences (P > 0.05) in digestibility coefficients between the two canola meals. Digestibility coefficients were higher (P < 0.05) for pigs fed the diets in which canola meal supplied only 50% of the supplementary protein compared with diets in which 100% of the supplementary protein was supplied by canola meal. Pigs fed toasted canola meal had similar weight gain, feed intake and feed conversion (P > 0.05) as pigs fed soybean meal while pigs fed non-toasted canola meal had lower weight gain and feed intake (P < 0.05) than pigs fed soybean meal. Feed conversion was unaffected by dietary treatment (P > 0.05). There were no significant effects (P < 0.05) due to diet on any carcass trait. The overall results of this experiment indicate that omitting the desolventization/toasting procedure from the process involved in the production of canola meal did not result in an improvement in the performance of pigs fed diets containing canola meal.

ABSTRACT The objective of this study was to evaluate the use of an enzyme complex-α-amylase, ß-glucanase, phytase, cellulase, xylanase and protease-in the feed of swine in growing and finishing phases, by assessing their performance (daily weight gain, daily feed intake, and feed conversion), dry matter, crude protein, and crude energy apparent digestibility, and the feed costs. Eighty pigs-castrated males, and females-of approximately 63 days of age and initial weight of 20.18±1.98 kg were distributed in a 5×2 factorial arrangement (diet × sex), in a randomized block design, with eight replications. The treatments used were: positive control diet consisted of 3,300 kcal/kg in the growth-I phase, and 3,250 kcal/kg in the growth-II and finishing phases; negative control diet with energy reduction of 85 kcal/kg of metabolizable energy (ME) (NC85); NC85 diet with addition of enzyme complex (EC85); negative control diet with energy reduction of 100 kcal/kg ME (NC100); NC100 diet with addition of enzyme complex (EC100). The addition of the enzyme complex to the diet with energy reduction of 100 kcal/kg ME increased the digestible protein content of the diet for the swine in the growth-II phase. The addition of the enzyme complex to the diet with energy reduction of 85 and 100 kcal/kg ME increased the digestible energy content of the diets for the swine in the finishing phase. The use of enzyme complex in diets with reduction of 85 kcal/kg ME for male swine in growing and finishing phases is recommended for improving feed conversion and economic efficiency during the growth-I phase. The use of enzyme complex is not justified for female swine.
