The aim of the present study was to evaluate the effects of feed particle size and flooring designs on organ traits, performance and pododermatitis in broilers. A total of 480 broilers (Ross 308) of both sexes were randomly assigned to two feeding groups (finely or coarsely ground pelleted diets; with addition of 5% to 10% intact wheat in coarsely diets) and four different housing systems (litter; litter with floor heating; partially or fully slatted floor) with three subgroups each. A coarse diet increased the final gizzard and pancreas weights (p < 0.001) while decreasing the risk of Isthmus gastrici dilatation compared to a fine diet (p < 0.001). Broilers fed a coarse diet displayed an increased final body weight (p = 0.023) and led to a favourable feed conversion ratio. Final body weight was the highest (p < 0.001) for birds housed on partially or fully slatted floor. Housing birds on litter with floor heating showed the lowest pododermatitis scoring (p < 0.001). It seems to be favourable to use coarse diets for organ development, whereas slatted floors seem to foster enlargement of the Isthmus gastrici. Increasing growth performance was possible both when using coarse diets or slatted floors.

Commercial Diet

The objective of this study was to develop the least-cost starter&rsquo;s diet and evaluated its effect on the growth performance of Sasso breeds and Indigenous ecotype of chicks under the local condition of the South Gondar Zone. The effects of substitution of different levels of commercial starters ration with homemade diet on the growth performance of Sasso and Indigenous chicks were studied in Hiruy Abaregay village of Farta district. The research area is 586km distant from the capital city of Addis Ababa, Ethiopia. A total of 510 Sasso T-44 and 90 Indigenous local ecotypes day-old chicks were randomly divided into five groups, each with 102 and 18 chicks, respectively. These were assigned into five treatments in which 100 (T1), 75 (T2), 50 (T3), 25 (T4), and 0% (T5) of commercial starter&rsquo;s diet in factorial completely randomized design (CRD) with 3 replications for 60 days feeding period. The results obtained indicated that increased levels of substitution of a commercial diet with a homemade diet significantly depressed (p&lt;0.001) mean daily feed consumption and retention of dry matter, nitrogen, and metabolizable energy. Growth rate as measured by mean daily weight gain, mean final body weight, and total feed consumption and feed cost were significantly miserable (p&lt;0.001) in an increased homemade diet. On the contrary, there was an increase in feed conversion ratio and fiber content in high-level dilution of starter&rsquo;s commercial diet with a homemade diet. However, the groups of chicks on 0, 25, and 50% commercial starters diets replaced by homemade diet were significantly higher (p&lt;0.001) in mean daily feed intake, daily weight gain, feed conversion ratio, and final body weight attained. The results of this study indicated that up to 50% of expensive commercial starter&rsquo;s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.

This study evaluated the effect of ginger on the growth performance, carcass quality of broiler chickens. A total of 40 broiler chickens were randomly selected into four groups identified as A (1% ginger extract), B (2% ginger extract), C (positive control) and D (negative control). All groups contain equal number of birds (n=10.) Birds were treated with aqueous ginger extract via drinking water. Significant variations (p<0.05) existed between the control and other treatments in mean final body weight, dressed weight, daily feed intake and feed conversion ratio. At the end of experiment (35th day) for 1% ginger extraction treatment the live body weight is 1745gm (p<0.05), dressing weight 1135.3 (p<0.05) and FCR is 1.66 (p<0.05). The usage of the test ingredients had a significant effect (p<0.05) on dressing percentage. Administration of ginger to broiler chickens increased their performance, FCR as well as blood parameters. It is, thus, recommended in broiler chicken production alternative to antibiotic and/or growth promoter.Res. Agric. Livest. Fish.4(3): 173-179, December 2017

A Completely Randomized Design (CRD) was comprised 2x3 factorial arrangements of two breeds (DYL and local breed) and three different lysine levels. The 18 weeks old, nine castrated DYL and nine local breed were randomly allocated in each individual pen to six treatment groups with three replicates into 18 pens. Two breeds of pigs (DYL and local breed) were exposed to the three different dietary treatments, L1- basal diet without lysine supplementation, L2- basal diet with 0.95% total lysine for finisher and L3- basal diet with 1.45% total lysine for finisher. The growth performance and back fat thickness were determined for finishing pigs. Significantly better body weight, weight gain, feed conversion ratio (FCR) and lower back fat were observed in pigs fed L2 but did not significantly differ from those fed L3. Otherwise, diets without lysine supplementation (L1) showed no better effect on the growth performances of both DYL and local breeds. It could be noted that L2 was the best level to obtain optimal growth performances and feed efficiency. Between the two breeds, growth performances of DYL were superior over that of local breed. Back fat thicknesses of DYL were also thinner than that of local breed. The interactions were observed between lysine levels and different breeds regard for final body weight, cumulative gain and feed conversion ratio. It was noticeable that lysine supplementation helped to improve growth performance and reduce back fat thickness of both local breed and DYL crossed breed. The result also showed that a comparison of the two different breed revealed the improved performances in DYL crossed breed rather than that of local breed.

Abstract The purpose of this study was to evaluate the growth performance of Peking ducks fed with rations containing waste products of leubiem fish (Chanthidermis maculatus) and probiotic agents. The study was conducted experimentally using 96 Peking ducks, within an age range of about 1 to 8 weeks, and a Completely Randomized Design (CRD), which consisted of four treatment rations and four replications. The treatment rations used in this research included treatment R0, which was the basal diet, serving as the control ration, and also treatment R1, R2, and R3, which consisted of 10% concentration of leubiem fish skin, head, and bone, respectively, as well as 1% of a probiotic agent. The observed variables included the rate of feed consumption, body weight gain, final body weight, feed conversion ratio, and mortality were then analysed using Analysis of Variance (ANOVA). The results showed that the use of leubiem fish components and probiotic agents in rations at 10% and 1%, respectively, had a significant effect (p<0.05) on the rate of feed consumption, body weight gain, feed conversion ratio and final body weight. However, there was no significant effect on the mortality of Peking ducks. Therefore, this study concluded that the use of rations containing leubiem fishbone and probiotic agents at 10% and 1%, respectively, were able to accelerate the growth performance of Peking ducks.

Dietary Treatments

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.   Keywords: broiler chickens, performance, total confinement, vermi meal

Foot Pad

In modern poultry production, foot pad dermatitis (FPD) represents one of the main problems on broiler chicken legs with significant affect on animal welfare and performance. This problem is not solved by the using of straw as litter. Different treatments of straw are needed to eliminate the adverse effects of this material as litter. The most widely used method to improve the quality of litter is chopping straw and application of microbial products on that. These procedures can decrease the moisture in the litter and reduce the population of microorganisms whose activity produces ammonia, and hence improving environmental conditions in facilities. The experiment involved four treatments with four replications with a total of 300 broilers per treatment. The treatment I was unchopped straw, treatment II was chopped straw, treatment III unchopped straw with the addition of microbial products, and treatment IV was chopped straw with the addition of microbial preparation. Duration of trial was 42 days. During the experiment, the following production parameters were measured: body weight per week of the experiment, feed conversion ratio, mortality and FPD. Results of the trial point out that the best production results were in treatment IV with an average final body weight of 2.456g and feed conversion ratio of 1.71.

The study was conducted to investigate the growth performance of broiler birds fed varying dietary levels of Artemisia annua. A total of 90 broiler chickens (Arbor Acre strain) were used. The study lasted for eight weeks. At the starter phase, 90 fourteen-day old broiler chicks were randomly allocated to five groups and fed starter diets containing five levels of A. annua (0, 50, 100, 150 and 200 g per kg of diet, respectively). At the finisher phase, 90 forty-two-day old finisher broilers were randomly allocated to five groups and fed finisher diets containing five levels of A. annua (0, 50, 100, 150 and 200 g per kg of diet, respectively). Each group was replicated three times with six birds per replicate in a completely randomized design. Parameter measured includes body weight, average daily feed intake, feed conversion ratio and protein efficiency ratio. The result of the proximate composition showed that Artemisia annua leaf meal contained 10.50% moisture, 26.27% crude protein, 5.00% crude fibre, 9.60% ash, 2.00% ether extract and 46.63% nitrogen-free extract. The result showed that at the starter phase, the inclusion of varying levels of A. annua in the starter diets had significant (p < 0.05) effect on the final body weight (FBW) of birds. Birds fed diet 2 (diet containing 50g of A. annua per kg diet) had significantly (p<0.05) higher final body weight (FBW) value (1115.00g) than those fed diet 5 (diet containing 200g of A. annua per kg of diet) which had FBW value of 915.00g. Dietary treatments had no significant (p > 0.05) effect on average daily feed intake (ADFI), total weight gain (TWG), average daily weight gain (ADWG), feed conversion ratio (FCR) and protein efficient ratio(PER) of the birds. At the finisher phase, significant (p < 0.05) differences existed among treatments in ADWG, TWG, FBW and ADFI. Birds fed diet containing 50 g A. annua per kg diet had significantly (p < 0.05) higher ADWG, TWG and FWG values than those fed the control diet. However, no significant (p > 0.05) differences existed among treatments in FCR and PER. It is concluded that A. annua leaf meal can be included in the diet of starter and finisher broilers at 200g per kg of diet without any deleterious effect on the growth performance of birds.

Cassava has the potential use to replace corn as an energy source in poultry feed.However, the level of substitution is not optimal because of the difference ratio ofamylose and amylopectin in maize and cassava. This study aimed to examine the effectof cassava flour with addition of isoamylase as a corn substitute in the ration on theperformance of broilers. The material used in this study was 150 male day-old chickenbroiler which were randomly divided into 3 treatments and 5 replications. Thetreatments were P0: 50% corn in the ration (control); P1: Substitution of 50% of cornby cassava flour; P2: Substitution of 50% of corn by cassava flour which contained0.14% isoamylase. The variables measured were feed intake, body weight, weight gain,feed conversion ratio, income over feed and chick cost and mortality rate. Data from thecomplete randomized design were analyzed using Analysis of Variance, the significantresults between the treatments were obtained by Duncan Multiple Range Test. Theresults showed that the substitution of corn by cassava flour without and with 0.14%isoamylase was not significantly affect final body weight, body weight gain, feed intakeand feed conversion ratio. The most profitable Income over feed cost obtained was thetreatment of P2 that is Rp 6,543.50. It can be concluded that the corn substitution bycassava flour without and with addition of 0.14% isoamylase was able to produce thesame performance as broiler chickens fed with corn in the ration for five weeks of thestudy.

Maize,which suppliesmost of the energy in poultry feeds, has low yields inNigeria and there is competition for the limited harvest of maize between industrial, livestock and human needs. Thus, this study was carried out to evaluate the effects on the growth and carcass characteristics of broiler chickens of replacing the high inputs grain,maize,with a low inputs grain, 'acha', or medium inputs grains, sorghum and millet. Four isocaloric and isonitrogenous diets for both the starter and finisher phases were formulated with maize, sorghum, millet and 'acha' as the main source of energy and were used as treatments 1, 2, 3 and 4, respectively.Marshall broiler birds were brooded up to 2 weeks before the treatments were introduced that lasted six weeks.Up to 8 weeks of age, body weight, average daily gain, feed conversion ratio and mortality were recorded weekly. The results of the study show no significant differences (P>0.05) between the four treatments in final body weight and average daily gain but birds on treatment 4 ('acha') had significantly lower feed intake and superior feed conversion ratio than the other experimental diets. Itwas concluded thatmaize can be replaced with sorghum, millet and 'acha' without adverse effects on the performance of broiler chickens.

The study was designed to evaluate the effects of administering extracts of garlic and Aloe vera in water on the growth performance and apparent nutrient digestibility of broiler chickens. One hundred and fifty, day old, Arbor acre chicks were used, in a completely randomized design, in seven treatments and each with three replicates. The experiment lasted for eight weeks. The garlic and Aloe vera extracts together with the antibiotics control (Sulfaquinoxalina) were administered at different doses via drinking water consecutively for three days and alternately at week 1, 3, 5 and 7, respectively. Treatment 1 received commercial antibiotics (Sulfaquinoxalina) at 2.67 g in 4 litres of water. Treatments 2 and 3 each received 0.40 mL of garlic and Aloe vera extracts in 4 litres of water which translated to 400 ppm. Treatments 4 and 5 each received 0.80 mL of both extracts in 4 litres of water (800 ppm) while treatments 6 and 7 each received 1.20 mL of both extracts in 4 litres of water (1200 ppm), respectively. The parameters measured were mean body weight, mean body weight gain, mean feed intake, mean feed conversion ratio, mean protein and energy efficiency ratio and apparent nutrient digestibility of feed as a result of the various doses of garlic and Aloe vera. Results showed no significant (p>0.05) differences in all the growth performance parameters measured for the first four weeks (starter phase). Feed conversion ratio, protein efficiency and energy efficiency ratio were affected (p<0.05) across the treatment groups at the last four weeks (finisher phase) of the experiment, with broiler chickens administered 400 ppm of garlic extract (T3) showing better performance (2.44, 2.42, 0.14) compared to those fed treatment 6 and 7 (1200 ppm Aloe vera and garlic). The apparent nutrient digestibility of the broiler chickens for all the nutrients were significantly (p<0.05) affected at both the starter and finisher phases of the experiment but no particular trend was observed. The total digestible nutrients were therefore calculated and it showed that birds administered 400 ppm Aloe vera extract (T2) at the starter phase and both 800 ppm of Aloe vera (T4) and garlic (T5) at the finisher phase, had better (p<0.05) total digestible nutrients compared to the control (90.69 vs 88.31; 91.10, 90.60 vs 88.59, respectively). It is concluded that the doses of 400 ppm (garlic) and 800 ppm (Aloe vera) extracts via drinking water improved feed conversion ratio, protein and energy efficiency ratio of broiler chickens at the finisher phase.
