Two experiments were conducted to assess the use, in broiler diets, of full-fat canola and flax seed or their restored mixtures of seed meals and oils. The first experiment compared raw and heated full-fat canola and flax seeds, and mixtures of the meals with the corresponding oils or animal tallow (ratios of 6:4, respectively), each added at 10% to the diet. The second experiment evaluated the raw full-fat seeds or mixtures of the meals with canola oil or animal tallow, added at 10 and 20% to the diets. Each experiment lasted 6 wk. Heat treatment did not significantly affect performance (P > 0.05). Dry matter and protein retention, and bird mortality were not influenced by dietary treatments. Diets containing 10 or 20% full-fat canola or canola meal plus oil mixtures resulted in similar body weight, feed conversion and carcass yield as the soybean meal control diet. In the first experiment, the inclusion of full-fat flaxseed depressed body weight, feed conversion and dietary metabolizable energy (ME) while the flax meal plus flax oil containing diets gave responses similar to the canola meal diets. In exp. 2, increasing the level of flax seed or flax meal plus oil mixture to 20% further depressed body weight and feed conversion. The ME and feed conversion efficiency of birds fed the full-fat seed containing diets were less than those obtained from birds fed the meal plus oil diets, but only significantly so for the flax diets. The type of fat fed with the meal had no effects on the responses of the birds. Key words: Chickens, canola, flax, heating, carcass yield, protein retention, metabolizable energy

The effects of enzyme supplementation on the performance, yield, and blood profile of broilers fed corn and soybean diets from 1 to 42 days of age were evaluated. A total of 960 male broilers were used, distributed in a completely randomized design, with six treatments and eight replications. Two diets were used: a positive control formulated to meet the birds’ nutritional requirements (Diet 1) and a negative control diet with reduction of 150 kcal.kg-1 of metabolizable energy (Diet 2) and 12% amino acid in the initial phase and 18% during the growing and finishing phases. Further diets were based on the negative control with enzymes: enzyme complex 1, composed of 125 g ton-1 protease; enzyme complex 2, composed of 100 g ton-1 amylase, protease, and xylanase; enzyme complex 3, composed of 500 g ton-1 amylase, protease, and xylanase; and enzyme complex 4, composed of 125 g ton-1 protease and 500 g ton-1 beta-mannanase. Enzymatic supplementation did not improve performance during the initial and growing phases due to nutritional imbalance, resulting in the worst weight gain and feed conversion during the finishing phase. Carcass yield, leg yield, abdominal fat, and pancreas were altered by enzymatic supplementation. Triglyceride levels influenced abdominal fat deposition, and the serum levels of albumin and alanine aminotransferase were altered by enzymatic supplementation. Enzymatic supplementation was not effective in restoring broiler performance, carcass yield, and cuts, with changes in the serum biochemical profile of the broiler chickens.

An experiment with broiler chickens was conducted to compare the relative bioavailability of liquid methionine hydroxy analogue free acid (MHA-FA) with that of DL-methionine (DLM) during fattening to 35 days of age. Ross 308 male chicks were allotted to 9 treatments, each consisting of six replicates of 140 birds/pen. Four graded levels (0.04, 0.08, 0.16, and 0.28 %) of MHA-FA or DLM products (weight/weight comparison) were added to a maize-wheat-soyabean meal basal diet deficient in sulphur amino acids. The criteria of response were body weight, feed conversion ratio, carcass yield and breast meat yield. Significant responses to graded levels of both methionine sources were observed in all response criteria. Using a multi-exponential model describing the dose-response relationships, the bioavailability estimates of MHA-FA relative to DLM on a weight-to-weight basis were 68, 70, 54 and 59 % for body weight, feed conversion, carcass yield and breast meat yield, respectively. If MHA-FA was compared with DLM on equimolar basis its bioavailability was 77.7, 79.0, 59.3 and 64.6 for body weight, feed conversion, carcass yield and breast meat yield, respectively. The bioavailability of MHA-FA for carcass yield and breast meat yield was significantly (P < 0.05) lower than that of DLM on a weight-to-weight and on equimolar basis.

A total of 200 Cobb 500 male broilers were randomly allocated to 4 treatments consisting of 5 replications with 10 chicks each in order to evaluate the effect of dietary garlic and thyme seed supplementation on the production performance, carcass yield and gut microbial population. Treatments were control diet (T1), control diet with 1% thyme seed powder (T2), control diet with 1% garlic powder (T3) and control diet with 0.5% thyme seed and 0.5% garlic powder (T4). Feed intake, body weight, weight gain, feed conversion ratio (FCR), carcass yield was not significantly (p>0.05) improved by dietary treatments compared to control. Escherichia coli (E. coli) count in the gut of broilers did not show significant difference among dietary treatments. However, Lactobacilli count in the gut of broilers significantly (p<0.05) increased in T2 compared to that of T1. Lactobacilli count in the gut of broilers received T1, T3 and T4 did not differ significantly (p>0.05) with each other. It was concluded that thyme seed was reliable as feed additive in the broiler diet and could provide positive advantages to the colonization and proliferation of Lactobacilli.

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

A total of 192 3-d-old male broiler chickens (Arbor Acres) were randomly assigned to six dietary treatments with eight replicates of four birds each per treatment. The treatments consisted of five levels (0, 50, 75, 100 and 125 U kg−1) of pectinase enzyme and a combination of pectinase (50 U kg−1) and α-galactosidase (6250 U kg−1) enzymes. The performance trial lasted for 2 wk. At the end of 2 wk, excreta were collected on three diets to determine nitrogen-corrected apparent metabolizable energy (AMEn). Growth rate, feed intake and feed conversion of birds fed pea diets supplemented with graded levels of pectinase enzyme were not different from their counterparts fed a diet without pectinase supplementation; however, growth rate tended to be improved (P = 0.11). Also, the AMEn values of these diets were not affected. Compared with the control diet, addition of a combination of pectinase and α-galactosidase tended to improve growth rate (P = 0.06). Key words: Peas, pectinase, α -galactosidase, broiler chicken

A broiler growth study was conducted to investigate the replacement value of canola meal (CM) for soybean meal (SBM) in broiler diets with or without the addition of two commercial enzyme products. A total of 3600 broilers were used in this experiment. Four isoenergetic diets replicated 10 times with 90 birds each were fed ad libitum as starter (Day 0–21) and finisher (Day 21–37) crumbles. All diets included a high proportion of sorghum as the main cereal component, and soybean meal (20% and 24.5%) or canola meal (35% and 28.9%) were included as the sole protein concentrate. At Day 38 selected birds from each dietary treatment were commercially processed and carcass yield and weight of selected meat portions were measured. The inclusion of CM in place of SBM and the addition of enzyme to CM-based diets did not affect feed intake, growth, and feed conversion ratio (FCR). Mortality in birds fed the unsupplemented CM diet was significantly reduced compared with the mortality in birds fed the SBM control diet or the CM diets supplemented with enzymes. Birds fed the unsupplemented CM had significantly (P < 0.05) reduced eviscerated weight, breast meat, and thigh yield and a significantly (P < 0.05) reduced water-holding capacity of muscle tissue compared with the SBM control diet. The addition of Enzyme A to CM-based diets increased breast meat and the addition of Enzyme B significantly (P < 0.05) increased dress yield, breast meat, and Marylands (thigh and drumstick portions). Carcass yield and quality on this diet was comparable to the SBM diet.

Abstract. Contemporarily, the production of high-grade ethyl alcohol enables obtaining dried distillers decoction that contains post-fermentation residues of cereal grains, solubles as well as yeast cells and their metabolites multiplied in the fermentation process, which makes that product applicable also in poultry feeding. Experiments were conducted on 540 broiler chickens of COBB 500 line. One-day chicks were randomly allocated to 3 nutritional groups: K, D1 and D2, each group consisted of 6 replicates of 30 birds. The factor that differentiated the groups was the content of dried wheat decoction in the starter type feed mixture (5% and 7%). Production results (individual body weight, feed intake and mortality) of the birds were controlled in a 42-day rearing period. On the 42nd day of rearing, 6 male and 6 female chickens from each group were chosen for slaughter that had body weights similar to the average of each group according to gender. The aim of this study was to determine experimentally whether the by-product of ethanol production is suitable for replacing soybean meal in feeding broiler chickens. The application of the wheat decoction had no negative effect on production results of the chickens. The birds fed a mixture with a higher content of dried distillers grains with solubles (DDGS) were characterised by a similar body weight and better feed conversion ratio compared to the control birds. A properly-balanced (fibre, energy, amino acids) nutritional dose of the dried wheat decoction may be used as a good energy-protein component in feed mixtures for broilers. It is a rational means of DDGS management which is, simultaneously, a cheaper substitute for soybean meal.
