Blood Biochemical Indices

A study was conducted to evaluate the effects of hot red pepper (HRP) powder as a natural feed additive on performance, immunity and blood biochemical parameters in broiler chickens. A Completely Randomized Design (CRD) was adopted by using 180 two weeks old Anak broiler chicks, allocated to four treatments with nine replicates of five birds each. Commercial broiler diets used containing HRP at the levels of 0%, 1.0%, 1.25% and 1.5%. Results showed that HRP supplementation did not significantly increase (p>0.05) the Average Feed Intake (AFI). Also not significant (p>0.05) but birds fed with the control diet had the numerically lowest Average Body Weight Gain (ABWG) (38.11 g) and worst Feed Conversion Ratio (FCR) (1.96). Better cost/kg weight gain was also found in the birds fed with the HRP supplemented diets. Mortality was however, significantly (p>0.05) higher in control diets compared to other diets. Packed cell volume (PCV), haemoglobin (HG), and white blood cell (WBC) levels were not significantly (p>0.05) different among the experimental groups. At the same time, HRP dietary supplementation did not have a significant effect on serum biochemical parameters (Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Lactate dehydrogenase (LDH), Low-density lipoprotein (LDL), High-density lipoprotein (HDL), triglycerides, cholesterol and glucose. Conclusively, hot red pepper (Capsicum annuum L.) inclusion up to 1.5% has the potential to improve feed conversion ratio and cost/kg weight gain, without affecting the blood biochemical indices of broiler chickens.

Two experiments were conducted to study the effects of either soluble or insoluble fibre naturally occurring in wheat and oats, on technical pellet quality and nutritional value for broiler chickens. In exp. 1, the effects of insoluble fibre were studied by mixing diets based on wheat or naked oats with either coarse or fine oats hulls followed by pelleting. Hull inclusion increased (P < 0.05) starch gelatinisation, especially in the diets based on oats. Addition of finely ground oats hulls improved pellet durability, in particular after storage, while no such effect was observed for coarse oats hulls. Oats hulls inclusion caused a more elastic pellet with higher breaking resistance (P < 0.05). Lower (P < 0.05) energy consumption was observed for diets based on oats compared with wheat, while no effect of fibre inclusion on energy consumption was found. In exp. 2, the influence of pelleting on the viscosity effect of soluble fibres in diets based on wheat or oats was studied. A significant increase (P < 0.05) in intestinal viscosity of broiler chickens was observed for all batches of grain exposed to steam pelleting. Viscosity was doubled (P < 0.05) with wheat diets, while the increase in viscosity was even greater in oat diets. In wheat diets, feed intake and weight gain was reduced (P < 0.05), while feed conversion ratio was not affected. Steam pelleting of oats reduced (P < 0.05) feed intake and weight gain, and increased feed conversion ratio (P < 0.05). The improvements (P < 0.05) in metabolisable energy and dry matter digestibility in wheat diets was not consistent with the observed increases in viscosity or with the results obtained with oats.

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.

An experiment was conducted to evaluate the effects of Bacillus coagulans ATCC 7050 (B. coagulans) on the performance, intestinal morphology and microflora of broiler chickens. Six-hundred 1-day-old broilers were randomly assigned into five treatment groups with four replicates for 42 days. There were five dietary treatments: negative control, positive control (antibiotics, 200 mg/kg zinc–bacitracin), 0.10, 0.20 and 0.25 g/kg B. coagulans. Dietary B. coagulans improved feed conversion ratio throughout the entire experimental period compared with the negative control (P = 0.02). Dietary B. coagulans significantly increased the number of lactobacilli (P = 0.01) and tended to decrease coliform bacteria (P = 0.06) in the duodenum. Dietary B. coagulans tended to increase villous height (P = 0.08) but had no effect on crypt depth in the jejunum. There were no significant differences (P > 0.05) in serum cholesterol, triglyceride, high density lipoprotein cholesterol and low density lipoprotein cholesterol between groups. In conclusion, the present data indicate that administration of B. coagulans ATCC 7050 improved feed conversion ratio in broiler chickens, possibly via improving the balance of intestinal microflora.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this experiment. Four broiler finisher diets were formulated with different inclusion levels of fermented cassava flour/blood mixture code-named “cassablood”. The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30%  cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD).Treatment effects on final body weight, final weight gain, feed intake and feed conversion ratio were significant (P<0.05). Birds fed cassabloodbased diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio. All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contents which differed (P<0.05) significantly Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.

The study was aimed at investigating the effect of oral administration of lime fruit on growth performance, haematology and serum biochemistry in broiler chicken. A total of 150, one day-old unsexed broiler chickens of Anak 2000 strain, were used in a completely randomized design (CRD). The birds were randomly allotted to five treatments with each group having 30 birds, replicated three times to give 10 birds per replicate. Treatment 1 was the control and had no additive; Treatment 2, had 5 mL of lime juice per litre of water every day; Treatment 3, had 7.5g of diced whole lime fruit per litre of water every day; treatment 4, had 5mL of lime juice per litre of water in alternate day while Treatment 5, had 7.5g of diced whole lime fruit per litre of water in alternate day. The experimental trial was for six (6) weeks after a brooding period of two weeks. Significant differences were observed in the final weight, feed intake, weight gain, and feed conversion ratio. Treatment 4 with 5mL of lime juice per litre of water in alternate day recorded better growth performance in the study, with weight gain and feed conversion ratio of 2963.35g/bird and 1.91, respectively. Results from haematological and serum biochemistry characteristics showed varied significant differences in some parameters. Haemoglobin values were between the range of 10.00g/dL in Treatment 3 and 11.80g/dL in Treatment 2. Total white blood cell (TWBC) was significantly highest in  Treatment 2 (75.20 x103 /µL), and least in Treatment 3 (66.20 x103 /µL). Total plasma cholesterol was highest in the control treatment with 133mg/dL and the least value was obtained from Treatment 2 with 104mg/dL. The study supports the use of lime fruit (juice or whole fruit) to promote growth and blood characteristics of broiler chickens which ultimately contributes to the improvement of the bird's overall productivity.

Feed Conversion

One method of reducing feed cost is to restrict the feed in the early life of broilers. In this regard, Fontana et al. (1992) reported that early feed restriction programs in their experiments proportionally reduced the consumption of the starter diets by an average of 22% in restricted broilers when compared with controls. Energy restriction has also been shown to result in a reduction in metabolic energy loss leading to a reduced requirement for maintenance. If during refeeding, this low requirement is maintained and if growth resumed at a normal or above normal rate (compensatory growth), feed efficiency would be substantially improved, leading to an economical advantage. This experiment was conducted to determine the effect of severity of diet dilution (energy and protein) and duration of early feed restriction on feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) of male broiler chickens.

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.

The aim of this study was to evaluated the effect of soaked Mucuna pruriens (MP) seeds in tap water, acid or alkaline solution + cooking on its L-Dopa content and on the productive performance of broiler chickens. Ninety-six sexed chicks aged 21-days old with an initial live weight of 720 ± 80 g were used. Four diets were used, a control without MP (C) and three diets including 25 % MP: a) soaked MP in tap water + cooking (WMP); b) soaked MP in acetic acid solution + cooking (AAMP); c) soaked MP in calcium hydroxide solution + cooking (CHMP). The alkaline treatment reduced 71 % of L-Dopa in comparison to acid or water treatment (53 % and 41 % respectively). In the starter phase, the acid group had the lowest live weight gain (p<0.05) and highest feed conversion ratio when compared to control (p<0.05). Productive performance of birds fed with CHMP and C group was similar (p>0.05). In the finisher phase, there was not statistical difference in feed intake, live weight gain and feed conversion ratio among treatments (p>0.05). No differences were observed in carcass yield (p>0.05), but, the birds fed MP or AAMP had a heavier liver than birds on C group (p<0.05). Results shown that 25 % of CHMP can be used as feedstuff for broiler chickens without negative effects in their productive performance. Keywords: Velvet bean, L-Dopa, Poultry, weight gain.

Hybrid Rye

In this paper, we present a study on the evaluation of the effect of xylanase addition to a diet with an increasing content of modern hybrid rye (Brasetto variety) on the performance indices and viscosity of small intestine content in broiler chickens. A total of 560 1-day-old male Ross 308 chickens were randomly assigned to 1 of 10 treatments, each comprising 7 replicate cages, with 8 male birds per cage. A 5 × 2 factorial arrangement was employed, with five dietary levels of ground rye (0%, 5%, 10%, 15%, and 20%). All the diets were either unsupplemented or supplemented with xylanase (200 mg/kg of feed; with minimum xylanase activity 1000 FXU/g). In the starter rearing period (1–21 days of age), the inclusion of rye (without xylanase supplementation) to the diet, even at the lowest dietary level (5%), negatively affected body weight gain (p < 0.05); there was no effect on feed intake and feed conversion ratio. In older chickens (the grower-finisher rearing period; 22–42 days of age), none of the dietary levels of rye (5–20%) affected growth performance indices. Similarly, no significant effect of increasing dietary level of rye was found for the entire rearing period (1–42 days of age). Diet supplementation with xylanase improved body weight gain and feed conversion ratio in chickens from 1 to 21 days of age. No positive effect of enzyme was found in older birds. No significant effects of the experimental factors used were noticed on the results of slaughter analysis, i.e., the carcass yield, breast meat yield, abdominal fat, and relative weight of the liver and gizzard. A high dietary concentration of rye (20%) increased the viscosity of small intestine content (p < 0.05); however, diet supplementation with xylanase significantly alleviated this effect. The findings of this experiment indicated that modern hybrid rye grain may be used at a 20% dietary level in broiler diets during the second feeding phase, i.e., from 22 to 42 days of age, without any detrimental influence on growth performance indices, while enzyme (xylanase) positively affected body weight gain and feed conversion ratio in younger chicks (1–21 days of age).
