Diets containing canola and soybean meal as the only source of protein and containing no supplemental niacin, choline or thiamine were fed to male broiler chickens from 1 wk to 6 wk of age. Supplementation of the basal diet with various levels of the vitamins failed to significantly alter weight gain, gain:feed ratio or percent bone ash values. Examination of the birds for leg deformities and difficulty in walking showed no difference between the basal and the vitamin-supplemented diets. It was concluded that the three vitamins investigated would not be factors in problems arising from the substitution of canola for soybean meal in practical type broiler diets. Key words: Canola, soybean meal, vitamins, broilers

Optimum inclusion level of boiled Mucuna cochinchinensis and its replacement value for soybean meal in both starter and finisher broiler diets were assessed using 400 unsexed 7-day-old broiler chickens in a completely randomised experiment. The boiled Mucuna meal was used to replace soybean protein at five levels (0, 19, 38, 57 and 76%) in isonitrogenous and isocaloric diets. Feeding of the experimental diets lasted 4 weeks in each of the starter and finisher phases. During the last week of each phase, three birds per replicate were selected and used for metabolism (nutrient retention) studies. At the starter phase, only bodyweight and daily weight gain were significantly depressed (P < 0.05) by inclusion levels of 38% and above, whereas bodyweight, daily weight gain, feed conversion ratio and protein efficiency ratio were depressed (P < 0.05) by inclusion levels of 57 and 76% at the finisher phase. At both phases, the inclusion level had a cost sparing effect such that the highest inclusion level resulted in the production of the cheapest diet and lowest cost per unit weight gain. The replacement and inclusion levels produced no significant (P > 0.05) effects on the retention of all the proximate components and energy at both starter and finisher phases. Therefore, on the basis of bodyweight and weight gain, the replacement of soybean protein by boiled M. cochinchinensis at 19 and 38% for starter and finisher phases, respectively, is recommended. These translate to 9.36 and 14.4% inclusion levels of boiled M. cochinchinensis in starter and finisher broiler diets, respectively.

Two experiments were conducted to compare the mineral profiles of canola and soybean meal. In a factorial arrangement, three supplemental levels of calcium (0.2, 0.4 and 0.6%) and three supplemental levels of available phosphorus (0.05, 0.1, and 0.15%) were fed with and without supplementation of 30 ppm of zinc. There was no response in weight gain, feed intake or percent bone ash, thus suggesting that zinc availability is unlikely to be a problem influencing the performance of poultry fed either of the protein supplements. Supplementation of both canola and soybean meal with either chloride, manganese, magnesium, iron or copper failed to demonstrate any meaningful responses which could be considered of interest in practical type diets in which the two protein supplements may substitute for one another. It is thus considered that none of the minerals investigated should be any more of a problem in practical type broiler diets in which canola meal is substituted for a portion of the soybean protein.

With the objective of investigating shrimp waste (SWM) and cassava leaf (CLM) meals as cheap alternatives and protein source mixtures that would best complement cassava root-soybean ration in total replacement for maize in broiler diets, six iso-energetic and iso-nitrogenous diets were evaluated using two weeks old Anak broilers in a growth and digestibility trial lasting seven weeks. Diet I was a maize-soybean based control diet while diets 2 to 6 contained whole cassava root meal (WCRM) in total replacement for maize, energy for energy. Diet 2 had soybean meal (SBM) as a major source of protein taking the protein supplied by SBM in diet 2 as 100%, SBM, CLM and SWM were combined thus in diets 3/0.5SBM: 0.5SIM), 4 (0.5SBM: 0.25SWM: 0.25CLAI), 5(0.25 SBM: 0.5SWM: 0.25CLM) and 6(0.5 SWM: 0.5 CL11). Average daily feed intake, weight gain (P< 0.01) and efficiency of feed conversion (P<0.05) were significantly influenced by dietary treatments. Results indicate that replacing up to 50% supplemental protein of soybean meal with equal proportion of supplemental protein from SWM and CLM had no deleterious effects on rate and efficiency of weight gain in broiler chickens. While nutrient and energy digestibility and carcass characteristics except dressing percentage were unaffected by dietary treatment, there was indication that organs such as gizzard and small intestine were significantly tasked for digestive function, evident from the considerable increase in their weights in birds fed diets in which over 50% of soybean protein was replaced by SWM and CLM. Based on the observation from this study, it can be concluded that not more than 50% of the dietary protein contributed by soybean should be replaced by SWM and CLM as doing otherwise would bring about a worsening effect on the performance of broilers.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Three experiments involving 11 600 male broiler chickens sought to determine if the pelleting process affects the dietary micronutrient, fat and protein components to increase the incidence of sudden death syndrome. Processed dietary micronutrient and fat components were not significantly associated with an increase in sudden death syndrome among broiler chickens. In one of the experiments, the incidence of sudden death syndrome was reduced (P < 0.01) when the dietary protein supplements (soybean meal, canola meal and fishmeal) bypassed the pelleting process. Key words: Sudden death syndrome, broiler chickens, feed pelleting, fat, micronutrients, protein supplements

The digestive utilization of minerals in Cu- and phytase-supplemented diets by weanling pigs was investigated in an experiment with a 3 × 2 factorial arrangement of treatments. Three levels of Cu (0, 60 and 120 mg kg−1 as CuSO4∙5H2O) and two levels of phytase activity (0 and 1500 units kg−1) were added to a corn-soybean meal basal diet. Seventy-two pigs (gilts:bar-rows, 1:1) with an average initial weight of 9.7 kg received the six diets for 21 d, after which 36 of the pigs were used in an 8-d mineral balance study. Phytase supplementation of diets increased serum P, Zn and Mg concentrations but reduced serum Cu concentration. The addition of Cu to the diets produced serum concentrations of minerals similar to Cu-unsupplemented diets. Absorption and retention of Ca and P were both slightly increased in pigs fed the phytase-supplemented diets compared with pigs fed diets that did not contain phytase. Addition of phytase to the diet that was not supplemented with Cu doubled (P < 0.1) Cu retention. Copper supplementation of diets did not affect absorption and retention of Ca, P, Zn, and Mg but increased absorption and retention of Cu and Mn. Results indicate that addition of phytase to P-supplemented and Cu-unsupplemented diets improves digestive utilization of P and Cu. Key words: Pigs, phytate, copper, phytase, minerals

One thousand day-old male chicken broilers housed in 16 floor pens to 42 d of age were used to study the effect of stevia on weight gain and feed consumption. The experimental design was a randomized complete block consisting of four diets (0%, 0.0085%, 0.0425% and 0.085% stevia) each replicated four times. Stevia did not appear to improve feed consumption or weight gain of broilers when used as a feed additive at the concentrations tested in this study.

Whole canola/pea (WCP, 1:1 wt/wt) or whole canola/canola meal (WCC, 3:1 wt/wt) were heat-processed using a commercial pellet mill prior to incorporation in broiler starter (0–20 d) and finisher diets (20–40 d). The pelleted blends readily disintegrated in the preparation of the mash diets. Body weight gain of broilers (0–40 d) fed WCP (0, 10, 20, or 30%) or WCC (0, 5, 10, or 15%) declined linearly with level of dietary inclusion (P < 0.01). Feed intake declined curvilinearly (P < 0.01) with both blends, with lower intake most apparent at the higher inclusion levels. Feed/gain increased for broilers fed WCP or WCC (P < 0.01). Overall broiler mortality declined incrementally with inclusion of WCP (P < 0.07) or WCC (P < 0.03) in the diet. Although there was no distinct limitation on the dietary inclusion levels of either blend, the low feed intake with broilers fed 15% WCC indicated that its level should not exceed 10% of the diet.

The aim of this study was to determine the calcium requirements of broiler chickens in starter phase with the addition of phytase enzyme. This experiment used 1,200 broiler chickens (mixed sex) for 21 days rearing period in a closed house. The basal diets was corn and soybean meal which contained 0.097% Ca and 0.123% P-av. The treatments consisted of 6 diets treatment: P1 (basal diet with the addition of 0.42% non-phytate phosphorus (NPP), and then P2 to P6 were basal diet with the addition of 0.22% NPP and 1,000 FTU/kg phytase and the addition of calcium (Ca) at different levels: 0.82% (P2); 0.74% (P3); 0.66% (P4); 0.58% (P5) and 0.50% (P6). The growth performance, feed efficiency, and bone mineralization parameters were studied using Oneway ANOVA in a Completely Randomized Design. Duncan's new Multiple Ranges Test was used to separate means with significant differences. Results showed that 0.90% Ca supplementation without phytase and the reduction levels of Ca from 0.82% to 0.50% increased the amount of feed consumed by birds in all growth phases (P<0.05). The addition of phytase had beneficial effects on increasing body weight (P<0.05) and average of body weight gain (P<0.05), and decreased the value of FCR in 11 - 21 days and 1 - 21 days. The addition of phytase increased protein and energy consumption, followed by increased in the value of PER and  EER (P<0.05). When phytase was added in the diets, reduction levels of Ca in the diets up to 0.50% did not give any adverse effect on the tibia bone ash. It can be concluded that feeding with phytase can sustain growth performance, feed efficiency, and bone mineralization.
