Influence of dietary fortification of cassava peel meal with Calapogonium mucunoides on performance of broiler chickens

The use of cassava peel meal (CPM) in broiler diets is not popular due to its negative effects. Hence an experiment was conducted to determine its dietary effect when fortified with Calapogonium mucunoides. One hundred and forty-four (144) one day-old Hubbard chicks were used. There were six dietary treatments (T1, T2, T3, T4, T5, T6) containing 24 birds each. Each treatment was replicated three times with 8 birds each on completely randomized design (CRD). T1 was the control diet containing no CPM. Treatments 2, 3, 4, 5 and 6 contained CPM fortified with 0, 10, 20, 30 and 40% C. mucunoides respectively. The CPM was fortified by substituting it for equal amount of C. mucunoides, mixed, ground, dried and sieved. Starter phase lasted for 28 days and finisher phase 21 days. The birds were fed and water given ad libitum for 49 days. At the starter phase fortified and non-fortified CPM did not improve performance compared to the control treatment. Non-fortified, 10% and 40% fortified CPM reduced live weight and feed intake. However, 20 and 30% C. mucunoides fortified CPM improved these parameters compared to the non-fortified group. Feed: gain ratio and protein efficiency ratio of the control and 20% fortified treatment were similar (P>0.05). Except protein efficiency ratio which was improved by 20% over the control treatment, fortification did not improve performance at the finisher phase. Live weight was better in 20% than in non-fortified. Feed and protein intakes were similar in non-fortified and fortified CPM. It was concluded that fortification of CPM with 20% Calapogonium mucunoides improved protein efficiency in broiler chickens.

An eight weeks feeding trial was conducted to assess the effect of feeding graded level of soaked pigeon pea meal (SPPM) in wood ash extract or solution on the growth performance, haematological and serum biochemical indices of broiler chickens. A total of 144 day-old chicks (Anak 2000) were randomly allotted to four treatment diets (1, 2, 3 and 4) in a completely randomized design. Each treatment group was replicated three times with twelve birds per replicate, thus, having thirty-six chicks per treatment group. Diet 1 contained 0% SPPM in wood ash extract for 72hours as the control diet, while diets 2, 3 and 4 were formulated to contain 25, 50 and 75% inclusions of SPPM in place of soybean meal. Results showed that the average live weight, daily weight gain and feed intake as well as protein efficiency ratio were significantly (P<0.05) influenced by the dietary treatments at the finisher phase. Broiler chickens fed 25% SPPM based diet had a higher (P<0.05) and comparable value of live weight, weight gain and protein efficiency ratio to that recorded in the control diet at the finisher phase. The haematological and serum biochemical indices revealed that albumin and total cholesterol were significantly (P<0.05) influenced by the treatment diets. The albumin value (2.2g/dl) was highest in birds fed 50% SPPM, whereas, the cholesterol value decreased (P<0.05) with increasing levels of inclusion of SPPM from 0 to 75%. It therefore implies that SPPM can be partially included in broiler diets up to 25% level with optimum growth performance and without any detrimental effect on the blood profile of broiler chickens.

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.

Treated Drinking Water

An experiment was conducted to determine the effect of treating drinking water with different organic acids on growth performance of broiler chickens. The organic acids were acetic, butyric, citric and formic acids. One hundred and fifty (150) day old Abor Acre chicks were used. The experiment was divided into five treatments with treatment 1 serving as the control, while treatments 2, 3, 4 and 5 respectively were offered drinking water treated with 0.25% acetic acid (AA), butyric acid (BA), citric acid (CA) and formic acid (FA). Each treatment was replicated three times with 10 birds per replicate. Feed and water were offered ad libitum. The experiment was arranged as completely randomized design (CRD). Results shows that except for BA organic acids significantly (P<0.05) improved final weight, daily weight gain, and protein efficiency ratio with AA having the highest (P<0.05) value at the starter phase. Also at the starter phase, daily water intake was significantly (P<0.05) reduced by BA, CA and FA. At the finisher phase, final body weight and daily gain were improved (P<0.05) by all the organic acids except BA. Final weight was better in AA compared to BA. There was no difference (P>0.05) in final weight between BA, Ca and FA. Daily feed and protein intakes were not affected (P>0.05). All the organic acids significantly (P<0.05) produced better feed: gain ratio. Only AA gave better protein efficiency ratio compared to the control. While AA, CA and FA encouraged water consumption, it was reduced (P<0.05) by BA. It is concluded that AA, CA and FA could be added in the drinking water for broilers for improved performance.

(Protein efficiency of broiler chickens fed with diets containing kayambang leaves meal)ABSTRACT The aim of the experiment was to determine the utilization of kayambang (Salvinia molesta) leaves meal until 18% based on its effects on protein consumption, protein intake, meat protein mass and protein efficiency ratio. One hundred broiler CP 707 day-old unsexed chicks, with an average body weight 502,48± 6,99 g age 15 until 42 days. This study used a completely randomized design (CRD) with 4 treatments and 5 replications and each replication consisted of 5 chickens.. The treatments diets were T0 (basal diet), T1 (6% Salvinia molesta leaves meal), T2 (12% Salvinia molesta leaves meal), and T3 (18% Salvinia molesta leaves meal). The results showed that administration of Salvinia molesta leaf meal up to 18% level in the diet resulted in a decrease in the quality of the ration so that the protein utilization also decreased as indicated by the decline in the value of protein intake, protein intake, protein mass of meat and protein efficiency ratio.

Positive Effect

Betaine is a methyl group donor that can increase protein synthesis since it has a similar role as methionine. The study was performed to determine the supplementation effect of betaine in the diet containing adequate methionine on growth performance and feed efficiency of female broilers. In total, 200 of day-old chicks of female broiler chickens were allotted to 4 treatments with 5 replicationsof 10 birds. This experiment was designed as completely randomized design. Control diet was formulated to contain adequate methionine (0.50% for starter and 0.38% for finisher period). The other dietary treatments were obtained by supplementing 0.1%, 0.2% and 0.3% betaine. The variables observed consisted of feed, protein and energy consumption, average daily weight gain, feed efficiency, protein and energy efficiency ratio. Supplementation of 0.1% betaine generated a higheraverage daily weight gain (P<0.05), but supplementation at higher levels (0.2 and 0.3%) had no effect on weight gain. However, betaine did not affect feed, energy and protein consumption, as well as feed efficiency and energy and protein efficiency ratio. Thus, betaine can be applied in the diet containing adequate methionine at the level of 0.1% to produce higherdaily weight gain without affecting feed efficiency. Supplementation of betaine at higher levels than 0.1% did not show positive effect on weight gain and feed efficiency in female broiler chickens.

Inclusion Level

An eight-week feeding trial was conducted to evaluate the growth performance characteristics of (120) broiler starter fed varying levels of parboiled sundried taro cocoyam (Colocasia esculenta) meal (PSCM). Four treatments were formulated with diet one containing 100% maize as control, while in diet two, three and four parboiled sundried cocoyam meal (PSCM) replaced the percentage proportion of maize in diet one at 50, 75 and 100% inclusion level respectively. Thirty (30) birds were randomly assigned to the four treatment diets in a completely randomize designed (CRD) each treatment group comprising of three replicates with ten (10) birds each. Growth performance revealed a significant variation (P<0.05) in the values of final live weight, daily feed intake and weight gain with highest value (1.62kg, 480.00g and 62.00g/bird) among those fed 50% PSCM. Feed conversion ratio (13.02) was least and best among those on 50% PSCM and protein efficiency ratio was higher (0.06) among those fed the control. It is concluded therefore from this study that parboiled sundried taro cocoyam meal is a valuable replacement for maize up to 50% in broiler diets without adverse effects on the growth performance of starting broiler chickens.

The aim of this study was to investigate the effects of methionine (Met) deficiency on antioxidant functions (in the duodenal, jejunal and ileal mucosa) and apoptosis in the duodenum, jejunum and ileum of broiler chickens. A total of 120 one-day-old Cobb broilers were divided into two groups and fed a Metdeficient diet and a control diet, respectively, for six weeks. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), the ability to inhibit hydroxyl radicals, and glutathione (GSH) content were significantly decreased in the Met-deficient group compared to the control. In contrast, malondialdehyde (MDA) content was significantly higher in the Met-deficient group. As measured by terminal deoxynucleotidyl transferase 2’-deoxyuridine 5’- triphosphate dUTP nick end-labelling (TUNEL) and flow cytometry (FCM), the percentages of apoptotic cells were significantly increased. In conclusion, dietary Met deficiency can cause oxidative stress and then induce increased apoptosis in the intestine. Oxidative stress contributes to intestinal apoptosis. This results in the impairment of local intestinal mucosal immunity due to oxidative stress and apoptosis in the small intestine. The results of this study provide new experimental evidence for understanding the negative effects of Met deficiency on mucosal immunity or the functions of other immune tissues.

An experiment was conducted to determine the dietary effect of different levels of ground black pepper (Piper nigrum) on growth performance and apparent nutrient digestibility of broiler chickens. There were five dietary treatments each containing 0, 0.25, 0.50, 0.75 and 1.00 % black pepper (BP) fed at both starter and finisher phases. One hundred and fifty (150) day old chicks of Arbor-acre strain were divided into five dietary groups having three replication with 10 in each. The five dietary treatments were randomly assigned into five groups. The birds were fed and watered ad libitum. At the starter phase 0.25 and 0.5 % BP improved live weight significantly (p<0.05). Feed intake was significantly (p<0.05) reduced at 1.00% BP. There were no significant differences (P>0.05) in daily gain, feed: gain ratio and protein efficiency ratio. At the finisher phase, final live weight was improved by 0.25% (p<0.05). Final live weight, feed intake, weight gain, feed: gain ratio and protein efficiency ratio were negatively affected by 0.75 and 1.0%BP. Fecal moisture was significantly (P<0.05) reduced by 0.25% while dry matter, protein and ether extract digestibility were improved by all the levels of BP. None of the BP levels improved crude fibre digestibility (p>0.05) over the control. NFE and energy utilization were improved by 0.25 and 0.5%, but significantly (p<0.05) reduced by 1.00% BP.Bang. J.
