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.

Three groundnut meals namely: groundnut cake (GNC), locally processed groundnut cake (kulikuli) and toasted groundnut seed(kernel) meal (TGSM) were incorporated in rabbit diets at two levels to generate six diets: 18% GNC, 22% GNC, 18% Kulikuli, 22% Kulikuli, 18% TGSM and 22% TGSM respectively, and 18% GNC also served as the control diet. Twenty four (24) six weeks-old growing rabbits of mixed breeds and sexes with mean initial weight of 568.75±l2.85g were randomly allocated to the six dietary treatment groups, such that each had four rabbits and each rabbit formed a replicate in a completely randomized design laid out in a 2X3 factorial arrangement and fed ad libitum, for 70 days. The main effects showed that while the treatment groups fed TGSM were significantly depressed (p<0.05). rabbits fed GNC and kulikuli were not significantly different (p>0.05) for average daily feed intake, daily body weight gain and final body weight. Feed conversion ratio (FCR) was not significantly (p >0.05) affected among treatment groups. Rabbits fed TGSM had significantly (p<0.05) better apparent digestibility coefficient (78.04%) than those on kulikuli (75.81%6) and the group on kulikuli were better than animals fed GNC (72.09%) for fat digestibility. Fibre digestibility was also significantly different (p <0.05), with rabbits fed kulikuli having the poorest fibre digestion (15.63 %). Crude protein, dry matter and NFE apparent digestibility coefficients were not significantly (p >0.05) affected. Among all the parameters measured, only fat and fibre digestibility coefficients had significant (p <0.05) interactions and NFE digestibility was significantly affected (p <0.05) by level of inclusion, with groups fed 22% digesting it better. Feed cost kg gain did not differ significantly (p >0.05) among the treatment groups. Growth was still on the rise and there was a significantly (P<0.01) strong relationship (correlation and regression) between feed intake and weight gain for all the treatment groups. was concluded that both kulikuli and TGSM are potential feed resources for rabbits, more available to house hold farmers, equally economical as GNC and better still if groundnut farmers and or processors of kulikuli raise rabbits, though TGSM had less value for growth rate compared to GNC and Kulikuli at these levels of inclusion

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.

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.

SUMMARYTwo experiments done at the University of Ilorin, Nigeria, in 1992/93 investigated the effects of dietary levels of thevetia cake on the performance and nutrient retention of broilers. In Expt 1, dayold broiler chicks were fed either a control diet or diets containing 5, 10 or 15% thevetia cake during a 4-week period. In Expt 2, day-old broiler chicks were fed a standard diet until 4 weeks of age and were then switched to diets containing 0, 5, 10 or 15% thevetia cake. Inclusion of thevetia cake in broiler diets, irrespective of level of inclusion, drastically reduced feed intake and weight gain (p < 0·01) at both the starter and finisher stages. Dietary thevetia cake also caused a significant increase in mortality rate (P < 0·01). There was a reduction in protein and fibre retention and dietary ME with increases in the dietary level of thevetia cake at both the starter and finisher stages (P < 0·05). It is concluded that thevetia cake is toxic to broilers and needs further processing before it can effectively be used as an ingredient in broiler feed.

The experiment was conducted at the livestock production and management unit, faculty of agriculture. MGCGV Chitrakoot – Satna ( M.P.). To complete the research work following steps were followed. Day old 75 broiler chicks (DOC) of same hatch were produced and reared in of Deep litter system. The chicks were weighed, leg banded and distributed randomly into five groups of 15 chicks each as treatment. Chicks of each treatment were further divided into three sub groups of five chicks in each in Randomized Block Design (RBD). Chicks of each sub group were accommodated comfortably in deep letter system providing 1 sq. ft./ chick. Chicks were fed standard starter ration upto 3 weeks age (1 to 21 days) and then broiler finisher ration upto 3-4 weeks (22-28 days). An experiment was conducted with DOC to 75 broilers chicks divided into five groups T0, T1,T2 and T4 which were supplemented with turmeric and Tulsi leaves powder @ 1.0g, 2.0g, 3.0g and 4.0g/kg of broiler ration, respectively. Weekly observations were recorded for live body weight, weekly gain in weight, weekly feed consumption and feed conversion of broiler for four weeks. Based on the results of the experiment, it may be concluded that feed supplementation with turmeric (Curcuma longa) powder influenced the body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on the result of the experiment, it may be concluded that feed supplementation with turmeric + Tulsi leaves powder influenced body weight, gain in body weight, feed intake and feed efficiency of broiler chicks. Based on feed intake and feed efficiency, the best performance of broilers was obtained with feed supplementation of 3g turmeric + 3g Tulsi powder per kg of standard ration (T3), followed by 4g turmeric + 4g Tulsi leaf powder (T4). Treatment T3 was economically superior over all other treatments and control.

The performance of broiler chicks fed on two common species of edible insects: African palm larva (Rhynchophorus phoenicis) and winged termite (Macrotermes bellicosus) in south east, Nigeria were studied using 135 day old Arbor acre birds. Three dietary treatments (T1, T2 and T3) representing Diet A (control: vital feed based fishmeal), Diet B (African palm larvae meal; APLM), and Diet C (containing winged termite meal; WTM), respectively, were used. T1 comprised of a standard feed of brand name ‘vital feed’ containing fishmeal which served as control while T2 and T3 both had insect meal: APLM and WTM, respectively, in place of fishmeal. Forty five broiler chicks were randomly assigned to each of the three dietary treatments at the rate of fifteen chicks per replicate and three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were subjected to similar husbandry and sanitation practices. Weekly record of feed intake, weight gain and linear body measurements were taken. Data obtained were subjected to ANOVA appropriate for completely randomised design and the differences between means were separated using least significant differences. The result showed that chicks fed with control diet based fishmeal (Diet A) had the highest feed intake compared to those fed Diet B and Diet C. Broiler chicks on Diet B however had the highest records in all performance indices (weight gain, feed efficiency ratio, specific growth rate, protein efficiency ratio and linear body measurements) investigated followed by Diet C and lastly Diet A. The study therefore recommends the use of insect meal for complete or partial replacement of fishmeal in poultry feed formulation.

A study was conducted to investigate the response of weaner rabbits to graded dietary replacement of wheat offal with dried citrus pulp (DCP) at 0, 10, 20 and 30% (weight/weight) respectively .A total of Sixty-four, male and female weaner rabbits of 56 days old, were randomly assigned to four dietary treatments with sixteen rabbits each and consisting of four rabbits per replicate in a completely ran- domized design. The study lasted for 112 days during which data was obtained on nutrient intake, performance characteristics and carcass yield. The crude protein intake of the rabbits decreased (P<0.05) significantly as the DCP inclusion in the diets increased. There were significant (P<0.01) differences in the values obtained for the final weight, total weight gain, average weight gain, meta- bolic weight gain and growth rate across the treatment groups. The growth rate was 10.29 g/d in the control fed rabbits but further decreased with increasing level of DCP in the diets with values of 11.29, 6.30 and 5.80g/d obtained respectively for rabbit fed with 10%, 20%, and 30% DCP inclusion level. The lowest feed conversion ratio was obtained at the 0% level of DCP inclusion. The retail cut parts indicated a significant (P<0.05) difference in the values for rack and ranged from 11.92 to 18.06g. It was concluded that although, rabbits fed with control diet had the highest overall performance, 10% dietary inclusion of DCP supported improved growth and better carcass yield.

The objective of this study was to evaluate the effects of feed supplementation with two prebiotic herbs—Origanum vulgare and Zingiber officinale—on growth performance of broiler chickens. The feed conversion ratio was determined weekly by dividing feed intake by body weight gain. A total of 400 one-day-old broiler chicks were divided into four treatment groups of four replicates of 25 chickens each using a complete design random. The four treatment groups were T0 (control), T1 (0.5% oregano), T2 (0.5% ginger), T3 (0.25% oregano + 0.25% ginger). The chicks were grown to 42 days of age. Weight gain, feed intake, conversion, carcass quality and mortality were determined weekly. Data analysis revealed that during the first 35 days of broiler chicken’s life, none of the dietary interventions had any effect on productive parameters (P > 0.05). However, during the last week of treatment, the oregano and ginger supplementation had a positive effect on weight gain and feed conversion (P < 0.05) than in the control group. In conclusion, the addition of oregano and ginger in the daily food ratio for broiler chickens during the last stage of the productive cycle improved the productive parameters, and carcass characteristics.

The purpose of this study was to investigate the effects of dietary addition of male and female Ferula eleaochytris powder (FEP) on growth performance and body components of broilers (Ross-308). Treatment groups were allocated to 5 dietary in which 0 (control), 5 g and 10 g male FEP, 5 g and 10 g female FEP doses per kg commercial broiler diet. In total, 80 male broiler chicks (1-d old) in which 16 animals in each group were used in study. Body weight gain and feed intake were monitored weekly for 6 weeks. Forty two days old broiler chicks were slaughtered to determine the possible changes in body components. The results of the study indicated that FEP had no effect on any parameters. However; the weight of the control group gave higher values than 5 g male Ferula group. In conclusion the measured parameters had no effect between all groups.

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. Key words: β-glucan, oats, chick, growth inhibition
