The study was conducted in poultry production unit of the Teaching and Research farm in the Department of Animal Science, Faculty of Agriculture, Usmanu Danfodiyo University to investigate the effect of graded levels of kapok seed meal on broiler bird’s performance. A total of 288 broiler chickens were being used. The broiler chickens randomly divided into four treatments groups (four experimental diets) T1 (control), T2 (0.5kg/100kg), T3 (1Kg/100kg) and T4 (1.5kg/100Kg). At the termination of the experiment (day 56), two birds from each pen (replicate) having representative weights for the group (6 birds per Treatment) were selected. The selected birds were bled, dressed and eviscerated. At starter phase the result shows no significant difference (P>0.05) between the treatments with regards to final body weight and average daily weight gain, birds in treatment 4 had higher (P<0.05) feed conversion ratio (FCR) compared to the other treatments. The result shows significant difference (P<0.05) between the treatments across all the parameters measured except FCR. Birds fed treatment 4 record higher values (P<0.05) of all the parameters measured compared to treatment 1 at finisher phase. The result on carcass shows significant difference (P<0.05) in terms of liver, lung, spleen and crop. Birds in treatment 2 have lower (P<0.05) liver compared to the other treatments. Higher (P<0.05) crop weight are recorded for birds in treatment 1 compared to the other treatments. The study concludes that ingredients of kapok (Bombax costatum) in poultry diet significantly (p<0.05) improved performance of broiler birds at starter and finisher phase at rate of 0.5kg/100kg inclusion of fed.

Two identical experiments were carried out to study the effects of four xylanases from bacterial or fungal origin supplemented to a wheat-based diet, on growth performance of broiler chickens and nutrient digestibilities. Experimental treatments consisted of a control basal diet containing 600 g kg-1 wheat (C), and the basal diet supplemented with 0.1 g kg-1 Grindazyme G from Aspergillus niger (G), 0.1 g kg-1 Belfeed B1100MP from Bacillus subtilis (B), 0.1 g kg-1 Roxazyme G from Trichoderma viride (R), or 0.0125 g kg-1 of a xylanase from Aspergillus aculeatus (A). Each experimental diet was given to four groups of six chickens each. Growth performance and feed conversion ratio (FCR) were recorded weekly, from 7 to 21 d of age. In the second experiment, a digestion balance trial was performed from 27 to 31 d of age to evaluate the nitrogen-corrected apparent metabolizable energy (AMEn) and the digestibilities of nitrogen, crude fat, starch and crude fibre. From 7 to 21 d of age, xylanase supplementation led to increased final body weight and daily weight gain, by 3.7 and 4.5 % (P < 0.05), respectively, without significant difference according to the xylanase origin. Xylanase supplementation significantly increased the AMEn (+2.6 %), and the digestibilities of crude fibre (+58.9 %) and nitrogen (+1.6 %). Increase in AMEn as well as in crude fat and starch digestibilities were significantly different according to the xylanase, but were not dependent on fungal or bacterial origin. In conclusion, the microbial origin of xylanases supplemented to wheat-based diets influenced neither the performance of broiler chickens nor the improvement in nutrient digestibilities.Key words: Broiler, growth performance, nutrient digestibility, wheat, xylanase

A trial was carried out to evaluate the effect of replacing wheat offal with rumen content on the growth performance of broiler chickens. A total of one hundred and fifty (150), one day-old broiler chicks were randomly allotted to five (5) dietary treatments containing 0, 5, 10% inclusion levels of sundried rumen content and 5 and 10% inclusion levels of roasted rumen content as a replacement to wheat offal. Each treatment was replicated three times with five (5) birds per replicate in a completely randomized design experiment. The trial lasted for eight (8) weeks. The results showed that there were no significant differences in the final weights, daily feed intake, daily weight gain and feed conversion ratio at the starter phase and finisher phases. Furthermore, no significant differences in the final weight (1346.60-1508.50g), daily feed intake (83.57-100.00g), and daily weight gain (36.43-39.53g), and were observed for the overall performance. However, there was a significant difference (P<0.05) in the feed conversion ratio with the highest being 2.69g and the lowest 2.33g in the overall performance. From these findings, it could be concluded that rumen content could replace wheat offal without any detrimental effect on the performance of broiler chickens.

Turmeric (Curcuma longa) is an extensively used spice, food preservative and coloring material that has biological actions and medicinal applications. Tumeric, when used as an additive could enhance the performance of broiler chickens in Nigeria. The aim of the present study was to assess the growth performance and haematological characteristics of starter broiler chicken fed diets supplemented with processed turmeric) meal (TM). Ninetysix, two weeks old unsexed “Agri-tech” broiler birds were randomly distributed in a completely randomized design (CRD) into four treatments, comprising of twenty four birds each, with three replicates per treatment (having 8 birds per replicate). The processed turmeric was included at the rate of 0%, 0.5%, 1.0% and 1.5% respectively. Feed and water were given without restriction. Supplementation of processed turmeric meal in the diet of starter broilers significantly (p<0.05) influenced the final body weight, average daily feed intake, average daily weight gain and feed conversion ratio. The treatment groups containing processed turmeric meal had poor performance in all parameters studied when compared to that of the control. Mean values of all haematological parameters evaluated namely; packed cell volume (PCV), haemoglobin (Hb), red blood cell (RBC) and white blood cell (WBC) differed significantly (p<0.05) between the control and the turmeric treated groups, however all the values obtained were within the recommended standard range of values for broiler. It was concluded that processed turmeric meal can be added to the diets of starter broilers up to the level of 1.5% and also can be safely used as a phyto-additive in starter broiler chickens, preferably in their feed.

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.

Two Nellore herds were compared, one selected for greater postweaning weight and the other, control, selected for average postweaning weight, to evaluate the effects of 29 years of selection on feed efficiency. Sixty Nellore males (41 selected and 19 control) averaging 205 kg and 267 days of age were evaluated in individual pens during performance test. Performance and dry matter intake were used to determine the following feed efficiency traits: feed conversion; residual feed intake; residual gain; partial growth efficiency; relative growth rate and Kleiber ratio. After the 112-day experimental period, control animals showed lower body weight when compared to selected animals, however, they did not differ for dry matter intake (% of body weight), rib-eye area and fat thickness at the 12th rib subcutaneous region and on the rump region. Dry matter intake (kg/day) and average daily weight gain from selected animals were, respectively, 19.4% and 26.4% higher than the control ones. The highest average daily weight gain by selected animals promoted significant improvement, around 6%, on feed conversion; 70 g/day on residual gain; and 17% on Kleiber rate. The other feed efficiency traits (residual feed intake, partial growth efficiency and relative growth rate) did not differ between herds. The 29-year selection for post-weaning weight did not affect feed efficiency of Nellore cattle.

 This experiment was conducted to determine the effect of dietary utilization of baobab leaf meal (BLM) on performance, carcass characteristics and hematological parameters of broiler chickens. Two hundred and twenty-five (225), one day old broiler chickens (Marshall Breed) were used for the study. Five diets were formulated containing baobab leaf meal (BLM) at dietary levels of 0, 2.5, 5, 7.5 and 10% designated as T1, T2, T3, T4 and T5 respectively. Chicks were randomly allotted to treatments in a completely randomized design (CRD) and each treatment was replicated three times consisting of 45 broiler chickens with 15 chicks per replication. The experiment lasted for eight weeks. Sample of BLM, experimental diet and faeces were analyzed for proximate compositions. Similarly, levels of anti-nutritional factors in BLM were also evaluated. The results at starter phase showed that the final body weight, daily weight gain and total weight gain were significantly (P < 0.05) higher at 7.5% BLM diet compared to other treatments. The feed conversion ratio (3.30) and feed cost in naira per Kg gain (N257) were significantly (P< 0.05) better at 7.5% BLM diet compared to others. The same trend was observed at finisher phase in the final body weight (2147.80g) and daily weight gain (52.39g). Similarly, feed conversion ratio (3.14) and feed cost in naira per Kg gain (N289.89) were significantly (P< 0.05) better at 7.5% BLM diet compared to other treatments. The results for carcass analysis showed that there were significant differences (P < 0.05) in final live weight (2.15 Kg) as broiler chickens fed 7.5% BLM diet had significantly (P< 0.05) highest values of carcass weight (1.52 Kg) and dressing percentage (72.04%). There were significant differences (P<0.05) in thigh muscle, back and small intestinal weights in which 7.5% BLM diet had the highest values across the treatments. Most of the organs weights were not significantly (P>0.05) affected by BLM inclusion with exception of crop and proventriculus. Therefore, it was concluded that BLM can be incorporated in the diet of broiler chickens up to 7.5% level without any adverse effect on the performance, carcass yield with concomitant reduction in the cost of production

The effect of distillers dried grains with solubles (DDGS) in broiler feed mixtures on the performance was studied in an experiment with 1000 male broiler chickens Ross 308 from 12 to 35 days of age. DDGS were produced from wheat (90 %) and triticale (10 %). Cockerels were divided into 5 groups and were housed on deep litter. Experimental feed mixtures were formulated to contain: 0, 10, 15, 20 and 25 % DDGS and were calculated as iso-nitrogenous. Weighing of chickens was realized at the 12th, 26th and 35th day of age. Control group of cockerels (0 % DDGS) had the highest final live weight and its average daily weight gain was significantly higher (P < 0.01) than in birds from groups with 10, 15 and 25 % DDGS. Broilers from control group (0 % DDGS) had the highest consumption of dry matter of feed mixture per bird. There were no significantly differences in feed consumption per bird and in feed conversion between groups. The results show that incorporation from 10 to 25 % DDGS decreased final weights and weight gains however there were no significantly differences in feed consumption and feed conversion.

The objective of the current study was to analyze the productive parameters of pigs housed in single and double capacity in the nursery, growth, and finishing phases in the Wean-to-Finish (WF) system. The research was carried out in the pig sector of the Centro de Ciências Agroveterinárias (CAV) at the Universidade do Estado de Santa Catarina (UDESC), in Lages, Santa Catarina. Ninety male castrated pigs weaned at 28 days of age and with an initial mean weight of 7.91 kg were used. They were housed in a WF shed and divided into two treatments: T1 with three animals per pen, 1.5 m2 of space per animal and 0.38 m of feeder space from weaning until slaughter; and T2 with six animals per pen, 0.75 m2 of space per animal and 0.19 m of feeder space in the nursery phase (up to 63 days old); and three animals per pen, with 1.5 m2 of space per animal and 0.38 m of feeder space for the growth and termination phases. The animals were individually weighed and the average daily feed intake (ADFI), average daily weight gain (ADWG), and feed conversion ratio (FCR) were calculated and a randomized design with a total of 10 replicate pens per treatment (with each pen considered an experimental unit) were used. Animals were slaughtered at 161 days of age. The design was completely randomized. We found no significant difference in ADWG, ADFI, or FCR in either the nursery or growth/finish phases and also found no significant difference in carcass yield. Our results show that double stocking pigs in pens is a viable alternative that allows for the best use of facilities during the nursery period on farms that use the WF system.

The aim of this study was to compare the effects of organic dietary zinc (Zn) sources and zinc sulphate on mineral deposition, activity of total superoxide dismutase (SOD) and copper/zinc SOD in tissues of broiler chickens. The performance indicators and lipid peroxidation by measuring the contents of thiobarbituric acid reactive substances (TBARS) in tissues and plasma were also evaluated. Broilers were assigned to 4 treatment groups, each replicated × 6, with 9 birds per replicate. The control group was fed conventional basal diet (BD); the three other groups received identical BD supplemented with 120 mg Zn/kg in the form of zinc sulphate, zinc chelate of glycine hydrate (Zn-Gly), and zinc proteinate (Zn-Pro), respectively. After 5 weeks of dietary treatment, feed supplementation with Zn sulphate resulted in significantly higher average daily weight gain and final body weight, as well as improved feed conversion ratio compared to the Zn-Gly group. Intake of Zn-Pro significantly increased SOD activity (P < 0.05) in erythrocytes and lipid peroxidation (P < 0.01) in plasma. Activities of total SOD and Cu/Zn SOD in liver and kidney were not affected by Zn supplementation. Addition of Zn supplements to broiler diets did not influence concentrations of zinc, manganese and copper in plasma, liver, kidney or breast muscle, with the exception of Zn deposition in the liver being significantly higher (P < 0.05) in the Zn-Pro supplemented group. Results of our study show that organic zinc sources have effects comparable to inorganic zinc sulphate in broilers fed diets containing a higher Zn content.

The aim of this study was to compare the virulence of porcine circovirus type 2 (PCV2) genotypes in dually inoculated pigs with both three genotypes (a, b, and d) of PCV2 and porcine reproductive and respiratory syndrome virus-2 (PRRSV-2) versus pigs singularly inoculated with the same three PCV2 genotypes (a, b, and d). Differences in this comparison were found in PCV2 viremia levels, lung and lymphoid lesion severity, and the amount of PCV2 antigen within the lymphoid lesions. Regardless of PCV2 genotypes, pigs that were dually inoculated with PCV2/PRRSV had significantly higher clinical scores, less average daily weight gain, higher levels of PCV2 viremia, and more severe lug and lymphoid lesions compared to pigs singularly inoculated with PCV2. Among the dually infected pig groups, pigs infected with PCV2d/PRRSV-2 had significantly higher levels of PCV2 viremia, more severe lung and lymphoid lesions, and more PCV2-positive cells within lymphoid lesions compared to pigs dually inoculated with PCV2a/PRRSV-2 and PCV2b/PRRSV-2. The results of this study demonstrated significant differences in the virulence among dual inoculation of PCV2a/PRRSV-2, PCV2b/PRRSV-2, and PCV2d/PRRSV-2. A significant difference in the virulence among PCV2a, PCV2b, and PCV2d single-inoculated pig groups was not found with respect to the levels of PCV2 viremia and production of PCV2-associated lymphoid lesions.
