The effect of a prebiotic mannan oligosaccharides (Actigen™) supplementation for 35 days was analyzed on growth, carcass traits and blood physiology of broilers. A total of 360-day-old broilers distributed under completely randomized design into four treatment groups with 24 replicates of 15 birds each was fed with Actigen™ supplemented diets @ 0.2, 0.4 and 0.6 g/Kg and a control diet. Data for growth performance were collected weekly while slaughtering data at 35th day. Results showed that the birds fed with Actigen™ added diet @ 0.6 g/Kg exhibited improved livability% (98.88±1.11), feed intake (3391.68±38.70 g), body weight (2157.66±31.52 g), weight gain (2111.49±30.89 g), FCR (1.57±0.03), dressing% (72.28±0.40), breast yield% (29.58±0.05), thigh yield% (31.61±0.30) and blood biochemical parameters. Superior (P£0.05) antibody response against ND and IB were recorded in birds exposed to Actigen™ supplemented diet @ 0.6 g/Kg. It was concluded that Actigen™ supplementation @ 0.6 g/Kg corroborated to improve growth, carcass traits, blood biochemistry and antibody response in broilers.

<p>This experiment was conducted to investigate the efficacy of methyl groups donor of betaine to spare methionine based on performance and carcass in broiler chickens. In total, 100 day old broiler chickenss were used in this experiment. They were allocated to 4 dieaty treatmants in 5 replicates with 5 broilers each. The basal diet was deficient in methionine. The control diet was obtained from basal diet supplemented with methionine to meet the requirements 5 g/kg diet for starter period and 3.8 g/kg diet for finisher period. The rest 3 treatments were basal diet deficient in methionine supplemented with 1, 2 and 3 g betaine per kg diet. The variables that were observed included average daily gain and carcass characteristics. The data were than analyzed by analysis of variance of Completely Randomized Design and continued with Dunnet test. The result indicated that supplementation of 1 and 2 g betaine per kg diet deficient in methionine resulted the broiler performance which was not different with supplementation of methionine. Accordingly, carcass characteristics for broilers fed diet supplemented with methionine were not different with that supplemented with betaine, which indicated that betaine may reduce the methionine level in the broiler diet. It can be concluded that betaine spares metionine in broiler diets.</p>

Mineral chelators such as organic acids have been reported to compete favourably with phytate by forming soluble complexes with feed minerals. Effect of feed grade acidifiers on total tract mineral retention and intestinal pH of broiler finisher chickens was investigated. A total of 300-broiler finisher chickens were assigned to four treatment groups. Each treatment was replicated thrice with twenty chickens per replicate in a completely randomized design. The control treatment (T1 ) was fed the control diet adequate in available phosphorus at 0.5% while other treatments (T2 -T4 ) were fed sub-optimal available phosphorus diets at 0.4%. Three blends of acidifiers; Fysal®, Orgacid® and Acidomix® were supplemented in the diets of chickens in treatments 2, 3 and 4 at 0.1% (1kg per ton/feed). Chickens fed diet supplemented  with Fysal® showed the best (P<0.05) results in total tract mineral retention 56.5+/-5.75 compared to the control and other treatments. The poor mineral retention i.e. 35 and 46% for calcium and phosphorus respectively by chickens fed the control diet was attributed to the insoluble phytate-mineral complex that limits mineral bioavailability. Intestinal segments of chickens fed acidified diets showed significant reduction (P<0.05) in pH in the range of 5.26-7.16 across duodenum to ileum compared to the control group 6.83-8.76. It is concluded that feed acidification at 0.1% improves mineral utilization in broiler chickens as it competes favourably with phytate in the lumen of the gut leading to better nutrient utilization.

Carcass traits and internal organs of one hundred and twenty, one day-old broiler chicksmaintained on different dosages of coffee weed leaf ethanolic extract for eight weeks werestudied. Five dosages (0, 25, 50, 75 and 100mL) of coffee weed leaf ethanolic extract(CWLEE) per litre of drinking water (T1 T2 , T3 , T4 and T5 ) were used. The birds were allocated \to the various treatment groups in a completely randomized design (CRD) with each treatment replicated three times (8 birds per replicate). Data on carcass traits revealed that live weight (2.50kg/bird), defeathered (2.30kg/bird) and eviscerated (2.00kg/bird) weights as well as dressing percentage (81.69%) were significantly (P<0.5) higher among birds on 50mL of CWLEE compared to those on other treatment groups. Similarly, the relative weights of drumstick (16.60%) and thigh (22.28%) were also significantly (P<0.05) better in broiler chickens administered 50mL CWLEE. Relative organ weights of broiler showed that weight of heart, lungs, gizzard, bursa, spleen and kidney were significantly (P < 0.05) influenced by the treatments. It is therefore inferred that birds administered 50mL CWLEE gave better carcass quality and functioning of the vital organs and therefore can be recommended for broiler chickens.

A feeding trial was conducted with two hundred (200) Arbor Acre strain of broiler chicks to determine the effect of soybean residue (SBR) on carcass characteristics and visceral organs. Birds were fed for 28 days (starter phase) with formulated diet containing 22% crude protein and 3000Kcal/kg (ME). Five iso-nitrogenous experimental diets were formulated which contain SBR. In the control diet (T1) groundnut cake was served as the only protein source. Four (4) test diets designated as: T2, T3, T4 and T5 were formulated with SBR replacing 25, 50, 75 and 100% of groundnut cake respectively in finisher phase. The birds were randomly grouped into five (5) experimental treatment groups in four (4) replicates of 40 birds per treatment in a completely randomized design. The finisher phase lasted for five (5) weeks and the birds were fed and given drinking water adlibitum. All carcass characteristics evaluated differ significantly (P<0.05) among treatment groups except breast and wings. No significant (P>0.05) difference were shown for organs, while shanks was only the residue that was significantly affected by dietary treatment. Soybean residue can be used up to 100% to replace groundnut cake in the diet of broiler chickens thus providing a productive use for this hither to neglected agro allied waste.

The gain body weight and Spoilage of meat broiler which giving jaloh extract to combine with chromiumABSTRACT. A study was conducted on broiler chickens under heat stress to evaluate the effect of combined jaloh (Salix tetrasperma Roxb) extract with chromium mineral in the body weight, value of feed ratio conversion, and time to meat to become decomposed. Twenty four of 20-day old Cobb female broiler chickens were randomly assigned and divided to 4 treatment groups. Completely randomized design was used in this study. The treatments were as follows: 1) chickens given no heat stress and jaloh extract nor chromium (tCp); 2) chickens under heat stress without given jaloh extract nor chromium (Cp); 3) chickens under heat stress and given jaloh extract in 1.000 mg/lt drinking water (Cp+Ej); and 4) chickens under heat stress, given jaloh extract in 1.000 mg/lt drinking water, and chromium in 1.000 ug/lt drinking water (Cp+Ej+Cr). Heat stress given was 33 ± 1oC of cage temperature during 4 hours per day within 15 days. Jaloh extract and chromium treatments in drinking water were given at 2 hour before cage temperature reaching 33 ± 1oC and were stopped being given after 1 hour, when cage temperature back to room temperature. On the 16th day of the study chickens were measured before slaughtered. Samples obtained were chicken meat that taken from breast part (musculus pectoralis). The result suggested that either giving jaloh extract per se at the dose of 1.000 mg/lt in drinking water or combine it with chromium that given two hours before cage temperature reaching 33 ± 1oC, can prevent chickens from decreasing their body weight, decreasing value of feed ratio convertion, and extending time to meat to become decomposed.

Performance Results

Two experiments were carried out to determine the nutritional value and to evaluate the performance and carcass traits in the growing-finishing pigs fed on two types of semipurified glycerin, which were made from vegetable oil (SPGV) and mixed of animal + vegetable oil (SPGM). In the digestibility trial (experiment I) 32 crossbreed barrows were used with initial body weight of 45.08 ± 4.11kg. It were used three levels of inclusion (6, 12 e 18%) of semipurified glycerin (SPGV and SPGM) in the basal diet. The metabolizable energy (ME) value of glycerin were estimated by regression of ME (kcal/kg) intake associated with glycerin vs. glycerin intake (kg). The values of ME (kcal/kg) obtained were: 2,731 for SPGV and 2,210 for SPGM. In experiment II, 72 pigs (30.08 ± 1.65 to 60.58 ± 3.57) in growing and (60.83 ± 2.63 to 93.79 ± 5.72) in finishing phase, were allotted in a completely randomized design in a 2 x 4 + 1 factorial scheme, with two types of semipurified glycerin (SPGV and SPGA), four inclusion levels (4; 8; 12 and 16%), eight experimental unit and a control diet containing no glycerin (0%). All pigs were slaughtered to evaluate the carcass traits. The performance results suggest that it is feasible to use up to 16% of both semipurified glycerins on growing and finishing pigs feeding, without impairing performance and carcass traits.

Abstract The objective was to evaluate the effects of including virginiamycin or bacitracin in diets containing monensin or monensin plus virginiamycin and bacitracin on growth performance and carcass characteristics of feedlot young bulls. Seventy-two young bulls, with an initial average body of 417 ± 38.7kg were allotted in a completely randomized design. The bulls were placed in 18 pens (four animals per pen), with three treatments and six experimental replicates. The diets consisted of 85% concentrate and 15% of corn silage, with 11.4% CP, 75.7% TDN and 18.4% NDF. The treatments were: MON, 25 ppm of monensin in the diet; MONB: monensin plus 8.75 ppm of zinc bacitracin; and MONVM monensin plus 25 ppm of virginiamycin. Feedlot had 109d, with 27d of adaptation and 82d of experimental period. Performance was measured by daily intake records and weighing at the beginning and end of the feedlot. After feedlot, animals were slaughtered to measure carcass traits. Serum D-lactate was collected on day 7 and 43 of the experimental period. There was no significant effect of the additives on performance and most of the carcass traits (Table 1). However, young bulls receiving MONVM tended to have greater LM area. On the other hand, MON diet tended to increase marbling. Finally, there was a tendency for treatment x time interaction (P &lt; 0.08) in the serum concentration of D-lactate. Bulls receiving MON had greater concentration on day 7 (109.5 µmol.µL-1), compared to other groups (66.7 and 89.9 µmol.µL-1 for MONB and MONVM, respectively). There was no effect of additives in the D-lactate content on day 43, being the treatments average 83.5 µmol.µL-1. In conclusion, the use of monensin and their association with virginiamycin or bacitracin did not affect performance but tend to influence carcass traits and serum D-lactate.

A four week study was conducted using 180 four weeks-old Abor acre broilers to determine the carcass traits and economics of production of finishing broilers fed cassava and yam peel meals as partial replacement for maize. They were randomly assigned to three treatment groups of 60 birds each. Each treatment group was replicated three times with twenty birds constituting a replicate. The three treatment groups were fed the three experimental diets in a completely randomized design (CRD) for 28 days. Feed and water were provided ad libitum for the period. Proximate composition results revealed that cassava and yam peel meals are rich in energy and minerals. Birds on diets T1 and T3 had similar (p > 0.05) final live and de-feathered weights, which were higher (p<0.05) than those on diet T2. Birds on diet T2 and T3 had the lower (p < 0.05) carcass weight than the birds on diet T1. There were no significant (p > 0.05) differences in the cut parts and organ weights, but there were significant differences in the dressing percentage of the birds across the treatments.  Revenue generated per bird was influenced (p < 0.05) with T3 birds having better income. It was concluded that sun-dried yam peel meal can replace 20 percent maize in the finishing broiler diet without adverse effects on performance and at reduced cost of productionKeywords: poultry, agro waste, unconventional feedstuffs, production traits, roots and tubers

Two hundred and twenty five, day-old Arbour Acre broiler birds were use to investigate the effect of graded dietary levels of Parkia biglobosa pulp meal (PBPM) on the performance, haematological and carcass parameters of the birds from 0-8 weeks of age. Five isocaloric and isonitrogenous diets were formulated to contain PBPM at 0,10,20, 30 and 40 percent respectively making a total of 5 treatments. Each treatment was replicated three times with 15 birds per replicate in a completely randomized design experiment. Feed and water were supplied ad libitum. Records taken included weekly weight changes and weekly feed intake. There was no record of mortality throughout the duration of the experiment. Results obtained showed a decrease in the bird’s performance as the dietary levels of the pulp increased. The final weight (g/b) and weight gain (g/b/day) decreased from 2122 and 33.91 for the control to1309 and 20.97 for the 40% inclusion level of PBPM meal respectively However birds placed on 10% dietary level had a performance that were not significantly (P>0.05) different from those placed on the control diet which were on standard broiler starter and finisher rations. Also it was observed that values obtained for the haematological parameters fall within the range often reported for healthy birds indicating that the pulp did not impart any deleterious effect on the health of the birds. It can be concluded that broiler chickens can be fed up to 10% dietary level of PBPM without adverse effect on the performance of the birds.

Abstract The effect of milled canola grain (MCG) in the diet of broiler chickens, from 1 to 42 days old, on performance, organ weight, biochemical profile, and carcass yield was evaluated. A total of 660 one-day-old male Cobb® broilers were distributed in a completely randomized design with six levels of inclusion of MCG in the diet (0; 5; 10; 15; 20, and 25%), totaling six treatments with five replicates of 22 birds. The canola used for the experiment was ground using a hammer mill with a 4.5 mm sieve to obtain a DGM of 955 µm. Performance data, organ index, blood biochemical profile, carcass yields, and cut up weights were evaluated. The data were analyzed by analysis of variance (ANOVA), and when there was significance Dunnett’ test was used to compare the inclusion levels the control diet. An effect was seen on mean weights and on feed conversion based on the inclusion level of MCG in the diets. The birds that received 20 and 25% inclusion of canola in the diet presented a worse performance in relation to that of the control. For the other variables analyzed, no effect of the treatments was observed when compared with the control (p > 0.05). It was concluded that the inclusion level of MCG in the diet of up to 15% can be used without losses to the performance of birds and without influencing the metabolism of the birds.
