An experiment was conducted to estimate the maximum amount of β-glucan that can be included in a broiler chick starter diet without impairing performance. Oat bran and fat were substituted for corn in a corn–soy diet to provide iso-energetic β-glucan levels of 6.3, 9 and 31 g kg−1 diet. Performance criteria were analyzed for regression on β-glucan level. Impairment of performance was greater for weight gain (W, g day−1) than for excreta condition or feed efficiency. An acceptable dietary β-glucan (G) level (g kg−1) was identified with the predicted performance equal to that of the control diet, from the response surface, W = 28.2 + 0.117 G − 0.00951 G2. Growth impairment was predicted to appear in young broiler chicks only as β-glucan level is increased in iso-energetic diets above 12.3 ± 0.46 g kg−1; conversely 1 and 2% growth inhibitions were predicted when dietary β-glucan levels equal 14.4 and 16.0 g kg−1, respectively.

The effects of raw and autoclaved Shoti (Curcuma zedoaria) meal on the growth and N utilization of growing broilers were determined. Shoti from Bangladesh Agricultural University campus was collected and sorted on the basis of white color of the rhizome. Then they were chopped into pieces, sun dried and pulverized in a flour mill. Aliquot samples were autoclaved at 1200C under 15 lb of pressure per square inch for 30 min. Autoclaved samples were stored in tightly lid contained for future use. 3 One hundred -day-old Cobb 500 broiler chicks were reared on the floor and a total of 24 growing broilers, 4 birds in each group were weighed on d 15 Two broilers were placed in each cage. There were a total of four experimental and two control (positive and negative Non-protein control) diets. Diets were fed ad libitum from day 15 to 33days. Body weight, feed intake, feed refusal and fecal weights were recorded every day. Cumulative feed efficiency per bird was calculated as the ratio of weight gained to feed consumed. Dry matter of excreta was determined from the last 10 d of feeding trial by drying aliquots of every day’s droppings by drying for 6 h at 1050C. On d 19, birds were bled to death. Immediately after slaughter, the carcasses were examined systematically. The chemical composition of Shoti meal showed that it is low in protein, fat and trace minerals and therefore mainly a source of energy. The bulk of the tuber (75 percent) consists of carbohydrates, made up of 10.6% fiber, and 64.9% nitrogen free extracts (NFE). A peculiarity of Curcuma rhizome meal contains high level of ash (9.9%) on DM basis. The results showed that at day 33, the weight of the broiler chicken fed shoti 100g, 200g, 300 g and 200g (autoclaved shoti meal)/ Kg diet was significantly different from the weight of the chicken fed on a maize-soybean diet. The birds given shoti meal consumed less feed than those provided with a maize diet. Feed efficiency or weight gain to feed ration over 19-d period was the poorest when fed 300 g Shoti/ Kg diet. Intake picked up when the shoti meal was incorporated after having been autoclaved and there was slight improvement in body weight gain as compared to that of other Shoti fed group. However, feed efficiency and body weight gain as % of initial weight remained significantly lower than the maize-soybean control. The inclusion of Shoti meal generally had an adverse effect on the apparent dry matter digestibility compared with the control diets. The group fed autoclaved shoti meal had a similar effect and the true N digestibility was the lowest when compared to those of control fed on maize-soybean meal. Thus, physical treatment like using autoclave, caused further reduction of digestibility of its N. Lipid digestibility was reduced by ingestion of shoti meal. Since the diets were isocaloric, after correction for the apparent endogenous lipid losses, which were obtained from the results of non-protein control feeding, the net faecal losses was around 66.2% of the ingested lipid against control diet fed birds.

A feeding trial was conducted for six weeks to assess the optimum replacement value of processed rock phosphate (PRP) for bone meal and as a source of inorganic phosphorus in maize-cotton seed meal based diets. A total of 144 day old Snack 80 strain broiler chicks were used. Triplicate groups of 12 birds were randomly placed on 4 diets containing 0. 1.8, 2.8 and 5.64% PRP which contributed 0,0.16, 0.25 and 0.5% inorganic phosphorus in the diets respectively, Results showed PRP levels in dicts had no significant (P>0.05) effect on weight gain, growth rate and feed intake at 0 - 4 weeks. When 2.8% PRP replaced 2% of bone meal, feed efficiency was not significantly different from those birds fed 3% bone meal in control diet. Inclusion of 5.64% PRP significantly (P<0.01) depressed feed efficiency more than other treatment groups during the period. Addition of 5.64% PRP supported higher growth rate than other treatment groups during 5 - 6 weeks, but this was not significantly different from birds fed on control and 2.8% PRP diets. Feed efficiency was significantly (P>0.01) lowest in the group fed on 1.8% PRP diet. Weight gain, growth rate and feed intake were not significantly (P<0.01) affected by treatments during 0-6 weeks. It was concluded that 5.6+% PRP which supplied 0.5% inorganic phosphorus supported optimum performance in broiler birds replacing 100% bone meal in a liu diet and caused growth that was equinob-ut to the group fed on 3% bone meal mentraal diet.

The present study was aimed to investigate the dietary effect of different levels of turmeric (Curcuma longa) powder on the performance of broiler during summer (June-July), 2013. Four experimental rations designated as T0, T1, T2 and T3 having 0%, 0.5%, 1.0% and 1.5% Turmeric (Curcuma longa) powder were fed to 120 broiler chicks (Ross 308), randomly distributed into 12 replicates, so as to have 3 replicates per treatment and 10 chicks per replicate. Average weight gain, feed consumption, feed efficiency, dressing yield and survivability were used as criteria of response to feeding turmeric powder. Organs weight including heart, liver and gizzard were also recorded. The mean body weight gain and average feed efficiency (feed gain-1) per broiler significantly increased (P<0.01) by turmeric supplemented feed compared to control feed. The average feed consumption and survivability of broiler chick non- significantly (P>0.05) improved due to by turmeric supplementation in the diets. Inclusion of turmeric powder caused slightly increased the carcass traits of broiler chicks i.e., average weight of liver, heart and gizzard but the differences were non-significant (P>0.05). A significant decrease (P<0.01) in abdominal fat pad and significant increase (P<0.05) in dressing yield was observed in chickens fed the turmeric supplemented diets. The results of the present study suggest that the use of turmeric (Curcuma longa) powder as feed additive at a level of 0.5% enhances the growth performances and carcass yield of broiler chicks.SAARC J.

The aim of this study was to valorize senescent plantain. Therefore, a traditional dish named Dockounou was prepared with a mixture of senescent plantain and various millet, soybean, sorghum, cassava, maize or rice flours. The growth performance of several Wistar rats feed by Dockounou was followed. Thus, batches of rats were fed for 15 days with three formulations (F1, F2, F3) in proportion of 90:10, 80:20 and 75:25 (senescent plantain dough/flours) obtained after two cooking modes (dry cooking: baked ; wet cooking: boiled). The effects of these formulations were compared to control diet (C. diet). Beyond the control diet, rats fed with the soybean baked Dockounou presented, the best following growth parameters: weight gain (2.82 to 4.19 g/d), food intake (8.92 to 9.72 g/d), feed efficiency (0.10 to 0.42), proteins intake (8.28 to 19.67), proteins efficiency (0.13 to 3.15). The physicochemical and nutritive characteristics of soybean baked Dockounou were as follow: ash (2.93 ±0.15 %), proteins (10.62±0.59 %), carbohydrates (15.46±1.53 %), calcium (232.04 – 558.20 mg/100g), potassium (313.97 – 385.11 mg/100g), magnesium (42.40 – 72.22 mg/100g), sodium (211.24 – 303.85 mg/100g) and phosphorus (330.70 – 433.71 mg/100g). Also, the study showed that, two formulations, 80:20 and 75:25, have really impact on rats growth. These results suggest that soybean baked Dockounou with important proportions, 80 % and 75 %, of senescent plantain dough can be effectively used in the diet of laboratory Wistar rats regarding the good zoological performances there are obtained.

Six hundred and seventy-two 1-day-old male broiler chicks of two strains were used to assess the effects of diet and color of diet on feed consumption. Isocaloric isonitrogenous diets that contained soybean meal (control), rapeseed meal, or ground rapeseed were fed in either colored or noncolored form. During the starter period the birds were given a choice of two diets in various combinations whereas during the grower period no choice was available. In the starter period there were no significant effects of color or diet combinations on total feed consumption. Coloring one diet of a pair, however, tended to increase the difference in consumption between the two by reducing the intake of the colored diet. The one exception to this was the diet pair containing ground rapeseed, which was not affected when one diet was colored. The control diet was preferred, followed by the diets containing rapeseed meal and ground rapeseed, respectively, when a choice was available. When no choice of diet was available in the grower period the only significant effect of color was to increase consumption of the ground rapeseed-containing diet. Weight gain in both periods was highest on the control diet followed by the diets containing rapeseed meal and ground rapeseed, respectively.

This work was carried out to evaluate the use of Bacillus subtilis probiotic C-3102 (10(10)cfu/g) in diets with or without growth promoters on the performance of broilers in the period from 1 to 42 days of age. It was used 1,200 Cobb line broilers, distributed in a complete randomized block with five diets: negative controller (without promoters); Bacillus subtilis (30 g/t ration); Bacillus subtilis (50 g/t ration); Bacillus subtilis (30 g/t ration) + colistin (10 ppm); avilamycin (10 ppm) + colistin (10 ppm). Each diet was evaluated in 10 repetitions with 24 birds. From 21 to 42 days of age, feed intake, weight gain and feed conversion were evaluated, and at 42 days of age, productive efficiency index was evaluated. At the end of the experimental period, it was observed an increase in the consumption of diet with the lowest dose of Bacillus subtilis (30 g) in relation to that one with Bacillus subtillis (30 g) + colistin (10 ppm). The values of weight gain obtained with the diet with the lowest dose of Bacillus subtillis (30 g) and with avilamycin (10 ppm) + colistine (10 ppm) were higher than those of the birds fed control diet (without promoters). For feed conversion, the best results were obtained by supplying diets containing 50 g of Bacillus subtillis, diet with 30 g of Bacillus subtillis + 10 ppm of colistin; and diet with 10 ppm of avilamycin + 10 ppm colistin. For the analysis of productive efficiency index, the best results were obtained with diets containing additives (probiotics and/or antibiotics) in comparison to the control diet. Bacillus subtillis C-3102 probiotic, at concentration 10(10) cfu/g, is an efficient substitute of antibiotics.

A study was conducted to determine the chemical composition and the nutritive value of boiled Christmas bush (Alchornea cordifolia) for starter broiler chickens. Dried Christmas bush fruits (Capsules + seed) were boiled for 30 minutes, sundried and ground into meal. The meal was analyzed for proximate composition and anti-nutritional factors and incorporated into broiler starter diet at 0%, 15%, 20% and 25% respectively. A total of 120 day old Marshall Strain broiler chicks were divided into 12 pens each containing 10 birds. Three pens were randomly assigned to each experimental diet. The boiled dried and ground Christmas bush (Alchornea cordifolia) fruit contained 19.9% crude protein and 4.7 mg/100 phytic acids which is an improvement when compared with raw Christmas bush fruits. Increase in inclusion level of boiled Christmas bush fruit in the diet caused a progressive reduction (p < 0.05) in final weight gain and feed intake of the birds. Birds on 15 and 20% BCBF had similar (p>0.05) feed conversion ration ratio with birds on control diet. The cost of feed per Kg weight gain and mortality were not significantly (p>0.05) different for all the treatments. Apart from Haemoglobin and serum phosphate, all other serum biochemical indices checked were not statistically (p>0.05) different among the treatment groups. It was concluded that boiling of Christmas bush fruits decreased the anti-nutritional factors and improved the nutritive value of the fruit but could not improve the performance of broiler starter chickens.

SUMMARYBroiler chicks reared under three environmental temperatures (7·2, 23·9 and 35 °C) in the Southeastern United States of America in 1988/89 were precision-fed to levels which were c. 70, 90, 110 and 130% of the consumption observed in ad libitum-fed controls at 23·9°C, in order to examine the limitations imposed by feed intake upon growth rate, feed efficiency and survival. Ad libitum-fed birds that were housed at 7·2, 23·9 and 35 °C consumed feed at 12·1, 9·4 and 8·5% of body weight, respectively. Liveweight gain of birds consuming feed ad libitum was depressed by 26 and 46% in the 7·2 and 35 °C environments respectively. Increasing feed intake by precision feeding exceeded ad libitum consumption in the 23·9 and 35 °C environments, but not at 7·2 °C. Consumption of feed above thermoneutral ad libitum levels failed to increase (p <0·l) liveweight of carcass gain. Ration digestibility and dressing out percentage declined (P < 0·05) at the higher feed intake levels in the 7·2 °C environment.
