A study on azolla as an economical substitute to soybean based poultry feed was conducted. The experiment consisted of four treatments laid out in Completely Randomized Design (CRD) with five replications. Each experimental unit consisted of three birds. For this purpose, eight-day old, unsexed Hubbard broiler chicks were weighed and randomly assigned to each treatment. Four different levels of azolla meal were incorporated in the starter and finisher ration at a level of 0%, 10%, 15%, and 20% respectively. Body weight, weight gain, feed consumption, and feed efficiency were measured. The average cumulative weekly body weight for all weeks were found to be significantly different (P<0.05) for the various treatments. Maximum cumulative body weight (1360 g) was found in broiler fed T2 ration in 5th week. Similar trend was also observed in 6th week showing highest cumulative weight (1882 g) in control diet (T1) which was at par with T2 (1841 g). Significantly highest (420.3 g) live weight gain was observed in T2 diet during 5th week. Overall mean of weekly feed consumption was recorded highest (784.33 g) in T2 diet. The economic analysis of net income/kg live weight was the highest (Rs 18.86) in T1 which was at par with T2 (Rs 18.35). Likewise, cost of production/bird was highest (Rs 124.5) in T1 and lowest (Rs 112.2) in T4. The results show that azolla meal could be utilized to substitute up to 10% soybean meal from overall production and economic point of view.Int J Appl Sci Biotechnol, Vol 3(4): 619-625

Slaughter Age

In this study, optimum slaughter age of the commercial broilers was estimated regarding maximum net income. Study materials were average target performance (live weight gain and feed consumption) of Cobb 500 and Ross 308 commercial hybrids, prices of feed, chicks and broiler meat. The optimum slaughter age was estimated by a mathematical function (y = f (x) = a+bx-cx2) that reflects the quadratic (parabolic) relationship. According to this function, the optimum slaughter age was calculated as 5.62 weeks (39.34 days). As a result, it can be said that genetic improvement positively affects the correlation between live weight gain and feed consumption of broilers. However, prices of feed, chicks, and broiler meat have more decisive role on slaughter age.

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.

A total of sixty, 14-day old broiler chickens (Cobb-500) of either sex were used in this study to assess the effects of processed cassava tuber meals (0, 15, 30, and 45 gkg-1) on growth responses, meat yield, and profitability of boilers; rearing from day 14 to day 33 of ages. The experimental diets were iso-caloric and iso-nitrogenous in nature, and were supplied the broilers ad libitum throughout the trial period. Broilers fed on control diet (i.e. exclusion of CTM) achieved higher (P<0.01) body weight, while the broilers offered diets with the highest amount (45 gkg-1) of CTM had the lowest body weight. Increased (P<0.01) feed intake was observed in the treatments of 21 d and 28 days of age when broilers fed diets with the supplementation of CTM, but no significant differences was found among the dietary treatments in the feed consumption of the broilers during 33 day of age. FCR differed significantly (P<.01) throughout the trial period, broilers fed diets without supplementation of CTM had the superior FCR than the others. Mortality was unaffected by all the dietary treatment groups. Moreover, different body parts (feather, head, neck, wing, viscera) and meat yields (thigh, drumstick, breast, back, giblet, dressing) were not influenced by treatments. Live weights were unaffected by all the dietary groups with/without incorporation of cassava tuber meals (CTM) up to day 21 and day 28 of  ages. Statistically significant (P<0.01) decreased live weight was observed among the treatments in 33-day old birds DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11552 J. Environ.

This study was conducted under the Department of Physiology and Pharmacology to determine the effects of Neem and Nishyinda leaves supplementation on growth performance and GUT biosis in broilers. A total of 40 day old broiler chicks were divided into four groups A, B, C and D. Group A was considered as control, fed only with commercial broiler ration. Group B supplemented with formulation of 2 gm grinded Neem leaves, Group C with 2 gm grinded Nishyinda leaves and Group D with 1 gm grinded Neem leaves plus 1 gm grinded Nishyinda leaves per liter of water respectively. Observations were recorded for live body weight, weight gain, feed consumption, feed efficiency, hemato-biochemical parameters and GUT biosis specially the parasite of birds in six weeks. Body weights were increased significantly (p<0.05) in all treated groups in respect to the control and highest was recorded in combine Neem plus Nishyinda supplemented groups (Group D). No significant (p>0.05) differences were observed among the groups for PCV and TEC values. Hb content increased and ESR decreased significantly (p<0.05) with combine Neem plus Nishyinda supplemented group (Group D). The serum SGOT and SGPT levels were also decreased with the same kind of supplementation. In treatment group there was significantly decreased of parasitic eggs, but in case of control group no decrease of parasitic eggs. There was no significant pathological change in any internal organs of the broiler of treated groups. Best result was found in the group D. The present study reveals that combine supplementation of Neem plus Nishyinda gives better result over other groups in respect to body weight gain, feed conversion ratio, hemato-biochemical parameter and profitability without making any health hazard of the broilers.

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.

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.

Coconut Meal

Coconut meal (CM) was included in a broiler diet to supply 40% of the total groundnut cake protein. The diet was formulated based on the recommendations of a previous study that coconut meal protein can replace 40% of groundnut cake (GNC) in broilers diet. A control diet was formulated containing 22% GNC, the protein of which was replaced by coconut meal protein. Five diets were prepared . The control (Diet A) and 4 others that contained essentially the same proximate composition (Diets B-E) were supplemented with synthetic lysine at 0.30, 0,60, 0.90 and 1.20% dietary levels. 240 broiler chicks were alotted into 5 dietary treatment groups of 3 sub-groupa. Each sub-group contained 16 birds. The dietary lysine content from diets A-E were 1.20, 1.15, 1.45, 1.76 and 2.00% respectively and were fed to the broilers for a period of 56 days. Performance indices, average feed consumption, average body gain, live weight, feed conversion ratio (FCR), protein efficiency ratio (PER) were monitored. The dry matter, protein and ether extractretentions were all equally monitored twice at the 4th and 8th week. Haematological and enzyme assays were investigated  at 4th and 8th week. The average feed consumption and FCR were significantly increased (P<0.05) by the increasing level of lysine supplementation both at the 4th and 8th week. The body gain also decreased significantly (P<0.05) at the 4th and 8th week while the live weight was significantly (P<0.05) better in the control and 0.6% lysine supplementation at the 56th day of the study. The dry matter, nitrogen and other extract retentions significantly decreased (P<0.05) at the 4th and 8th week. The total protein and albumin decreased significantly (P<0.05) at the 4th and 8th week while, creatinine and urea increased with increasing level of lysine supplementation. The serum glutamate amino transaminase and alanine amino transaminase both increased significantly (P<0.05) at the 4th and 8th week. The study indicated that 0.6% lysine supplementation (of diet containing coconut meal contributing 40% protein of the major vegetable protein source) enhance the utilization of the coconut meal by broilers.
