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.

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

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.

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.

Several efforts are being made to find the possibilities of utilizing agro-industrial by products in poultry nutrition. The deployment of maize milling waste for feeding broilers has a promise for reducing its nuisance value, yet enhancing the feeding of broilers. An eight weeks' study was carried out with 108 day-old Anak broiler chicks, to evaluate the performance of broiler chickens fed diet containing maize milling waste as a replacement for maize. Maize milling waste was analyzed for its proximate composition. It was then used in formulating starter and finisher broiler diets at 0.0%, 10%, 30%, 50% dietary levels. The formulated diet was fed to the chicks in a Completely Randomized Design (CRD) experiment. The parameters evaluated were the initial body weight, final body weight, average feed intake, feed conversion ratio. The results obtained indicated that broiler chicks on 0.0% maize milling waste recorded the highest weight gain and feed conversion ratio followed by birds on 10% maize milling waste inclusion level. The feed intake of birds increased as the level of replacement increased. Birds on 50% milling waste had the highest feed intake which was significantly different (P<0.05) from the other treatment diets. From the results of this study, the growth performance in diet 1 (0.0%) maize milling waste inclusion level was superior to others, followed by diet 2 (10%) inclusion level. Therefore, for efficient utilization and without deleterious effects, 10% inclusion level of maize milling waste should be used in feed formulation.

This research aimed to study the effect of different energy and protein balance in quail feed on feed consumption, weight gain, and feed conversion ratio. One hundred and twenty day old quails were divided into 24 units enclosure research. The trial feed was consist of 2 levels of energy feed (2700 and 2900 kcal/kg) and 3 levels of crude protein (18, 20, and 22% CP), so that there were 6 combinations of treatments, i.e. R1 (2700 ME – 18% CP), R2 (2700 ME – 20% CP), R3 (2700 ME – 22% CP), R4 (2900 ME – 18% CP), R5 (2900 ME – 20% CP), R6 (2900 ME – 22% CP). The used feed was a self mixing feed. The observed parameters were feed consumption, body weight gain, and feed conversion ratio of quail at 2-6 weeks of age. The data obtained were analyzed using variance analysis and continued using Duncan’s multiple range test. The result showed that the balance of energy-protein in quail feed did not affect (P>0,05) feed consumption, body weight gain, and feed conversion ratio. The combination of 2700 kcal/kg metabolizable energy and 18% cruse protein could already maintain the needs of the grower period of quail nutrients.Keywords: protein, energy, quail, grower

The present study was conducted to determine the effect of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120, one-day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate in a completely randomised experimental design, with 4 silicon levels (0.00, 1.50, 2.00 and 2.50 mg of silicon oxide/litre of water. Corn-soya based diets were formulated at the starter (0–4 weeks) and finisher (5–8weeks) phases and were supplied ad libitum with free access to water. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. At the starter phase, chicks administered 2.00mg silicon oxide/litre of water had significantly (p<0.05) higher final body weight (991.00g) and average weight gain (950.96g) compared to chicks without silicon oxide 778.57 g and 738.54g. The inclusion of 2.00 mg silicon oxide/litre of water improved feed conversion ratio compared to the control group (p < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, chickens administered 2.00mg silicon oxide/litre of water had the best results for final weight, weight gain and feed cost per kg gain. Also, inclusion of silicon oxide in broiler chickens water improved litter quality as predominantly dry material but with some areas of wet shavings was observed. In conclusion, silicon oxide in broiler chickens drinking water at 2.00mg/litre of water enhanced growth performance, improved feed conversion ratio and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.

SummaryA total of 432, one-day-old broiler chickens were randomly assigned as a 2 × 4 factorial design (pellet or mash and 0, 25, 50, and 75% whole sorghum levels) in a completely randomised experiment, having six replicates with nine birds per replicate. Body weight and feed intake were measured on a pen basis at 10, 25, and 35 days of age and feed conversion ratio calculated. Pelleting diets significantly improved (P<0.05) feed intake, body weight and carcass yield of broiler chickens at 10 and 24 days of age. Heavier relative gizzard weights with lower pH (P<0.05) were recorded for broiler chickens offered mash diets at 35 days old. Feed conversion ratio at 35 days of age increased (P<0.035, quadratic effect) with higher levels of whole sorghum and levelled off at 75% inclusion rates. Relative gizzard weight at 35 days was marginally increased (P<0.033, linear effect) in line with rising sorghum levels. Similarly, relative bursa and liver weights at 35 days increased (P<0.037, quadratic effect and P<0.033, linear effect, respectively) with sorghum inclusion. The results showed that pelleted diets gave superior performance compared to mash diets. Although higher levels of sorghum inclusion in mash diets enhanced gizzard development, performance parameters of birds at 35 days of age were poorer, with 125 g less body weight and an increase in FCR from 1.51 to 1.62 for the 0% and 75% sorghum levels respectively.

The objective of this study was to investigate whether melamine (MEL) is biotransformed into cyanuric acid (CYA) in male broiler chickens. The effects of the dietary addition of MEL and CYA alone and in combination on the growth performance and mortality of the chickens were also investigated. The chickens were divided into six experimental groups and were fed diets with an addition of 50 or 100 mg/kg MEL or 50 or 100 mg/kg CYA of diet, with the contaminants added separately or in combination. The control group was fed a diet without MEL or CYA. At the end of the experiment (day 40), samples of liver, kidney and breast and thigh muscles were collected from 12 birds per treatment group and were analysed for the presence of MEL and CYA. This study showed that MEL is biotransformed into CYA in broilers. Higher concentrations of MEL or CYA in the diet increased the presence of their residues in tissues, and the CYA residue concentration was several times higher in the respective tissues than the MEL residue concentration. The dietary addition of MEL and CYA did not affect the mortality rate, feed conversion ratio or body weight of the chickens.

One of the widespread spices is garlic which consumed by people of different parts of the world but its valuable growth promoting effect is not sufficiently studied in poultry. Growth promoting effect of garlic in broiler chickens was studied together with its carcass characteristics and blood parameters. Broilers were grouped into four: A (1%), B (2%), C (positive control) and D (negative control).  Aqueous extract of garlic (1% and 2%) was prepared by extraction and were administered with drinking water. A group (1%) shows best performance with regards to body weight gain rather than B (2%), positive and negative control. At the end of experiment (35th day), in A group, the live body weight, dressed weight, feed conversion ratio, liver, gizzard, heart, spleen, and pancreas were 1833.2±2.1g (P<0.05), 1229.7±1.9g (P<0.05), 1.63(P<0.05), 47.13±0.4g, 26.15±0.7g, 9.71±1.8g, 2.21±0.2g, 2.27±0.1g respectively. The mean Total Erythrocyte Count (TEC), Haemoglobin concentration (Hb) and Packed Cell volume (PCV) were 2.9± 0.1million/cm3,7.5g ± 0.2g, and 25.8 ± 0.6%, respectively. It is recommended that 1% aqueous extraction of garlic shows better growth and improved carcass qualities in broilers.
