Day-old unsexed broiler chicks (Cobb 500) were used to investigate the growth responses and meat yield traits by nourishing them under four dietary treatment group in inclusion of cassava meal with partial substitution of valuable energy source (maize or corn). A total of 260 birds were assigned randomly into four dietary treatments [T1 (0%); T2 (10%); T3 (20%), and T4 (30%)]; each replicated 5 times, 13 birds/replicate in a completely randomized design. Birds were reared with ad libitum feeding, similar housing, and environmental management condition from d1-35 days. Growth responses of broilers in terms of feed intake, body weight, feed conversion ratio (FCR), livability and meat yield traits were assessed in this study. Except for first week, the feed intake of birds on cassava treated diets up to 21 and 35 days was significantly (p<0.001) higher than the non-cassava or control diet (T1). Feed intake of broilers on cassava treated diet (T4 ) had the highest (2795.8 g/b) while the birds of control (T1) diet group consumed the lowest feed (2771.9 g/b) at 35 day. Live weight decreased (p<0.001) with the inclusion of cassava meal diets up to 21 day only; and live weights up to 7 and 35 days were identical between treatment. FCR up to 21 day was improved (p<0.001) on control diet (T1) and deteriorated on cassava treated diets. FCR values up to 7 and 35 days were unaffected by all the treatment groups. Neither the livability nor the meat yield traits (thigh, breast, drumstick, shank, neck, giblet, wing and dressing yield) of broiler chickens was influenced by the dietary treatments regardless of feeding broiler chickens with cassava or non-cassava diets in this study. It may be deduced based on the present findings that, cassava tuber meal might be a potential ingredient to replace the costly maize up to 300 g kg-1 without affecting growth performance of the broiler chickens.

A total of sixty, 14-day old broiler chickens (Cobb-500) of either sex were used in this study to assess the effects of processed cassava tuber meals (0, 15, 30, and 45 gkg-1) on growth responses, meat yield, and profitability of boilers; rearing from day 14 to day 33 of ages. The experimental diets were iso-caloric and iso-nitrogenous in nature, and were supplied the broilers ad libitum throughout the trial period. Broilers fed on control diet (i.e. exclusion of CTM) achieved higher (P<0.01) body weight, while the broilers offered diets with the highest amount (45 gkg-1) of CTM had the lowest body weight. Increased (P<0.01) feed intake was observed in the treatments of 21 d and 28 days of age when broilers fed diets with the supplementation of CTM, but no significant differences was found among the dietary treatments in the feed consumption of the broilers during 33 day of age. FCR differed significantly (P<.01) throughout the trial period, broilers fed diets without supplementation of CTM had the superior FCR than the others. Mortality was unaffected by all the dietary treatment groups. Moreover, different body parts (feather, head, neck, wing, viscera) and meat yields (thigh, drumstick, breast, back, giblet, dressing) were not influenced by treatments. Live weights were unaffected by all the dietary groups with/without incorporation of cassava tuber meals (CTM) up to day 21 and day 28 of  ages. Statistically significant (P<0.01) decreased live weight was observed among the treatments in 33-day old birds DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11552 J. Environ.

An experiment was conducted to compare the haematology and some serum constituents and performance of broilers fed diets containing improved (addition of anti-microbial and anti-oxidant) locally produced natural vitamin premix (LPNVP), LPNVP without improvement and commercial vitamin premix (CVMP). Haematology of the birds was not affected by the dietary treatments. However, red blood cell (RBC) count was significantly high (P<0.05) for the birds fed diet containing improved LPNVP The haemoglobin, PCK, RBC and WBC values observed for birds fed improved LPNVP were 13 gm%, 32%, 246 x 1012/L and 3.1 x 1010/L respectively. Serological parameters observed in the study were not significantly different (P>0,.05) for all the dietary conditions studied. Birds fed diet containing improved LPNVP also recorded comparable serum components to control diet containing the commercial vitamin/’mineral premix. Serum calcium, phosphorus, glucose, ureate, creatinine and total protein observed for birds fed diet containing improved LPNVP were 2.32%, 0.70%, 3.60Mmo/L, 2.9Mmo/L, 0.25Mmol/L, 58Mmol/L and 66g/100ml respectively. Feed intake, weight gain and feed utilization were similar (P>0.05) for the various dietary treatments. Birds fed improved LPNVP based diets tended to record better feed intake than did the control birds on CVMP based diets and unimproved LPNVP. Generally, improvement of LPNVP tended to give better performance of broilers than did other dietary treatments.

The study was conducted to investigate whether the productive performances and meat yield characteristics of broiler would be improved by feeding diet containing koroch (Pongamia Pinnata) seed cake (KSC) treated with NaOH and HCl. A total number of 160 day-old straight run broiler chicks were fed on 4 iso-energetic and iso-nitrogenous diets containing either basal diet with no KSC or basal diet containing 2% KSC treated with or without 1% NaOH or 1% HCl for a period of 28 days. These diets were considered as 4 different treatments. Each treatment was replicated 4 times, each having 10 birds. Inclusion of 2% KSC treated with NaOH or HCl in the diet resulted in lower live weight, live weight gain, feed intake, feed efficiency of broilers at all ages compared to inclusion of dietary 2% KSC alone (P<0.01). However, broilers, irrespective of age, fed on diet containing 2% KSC treated with 1% HCl exhibited better productive performances than those fed on 1% NaOH treated 2% KSC incorporated diet. The amount of feed intake of broilers on either KSC alone or HCl treated KSC was almost similar to that on control diet. The meat yield parameters showed a non-significant treatment effect except for the percentage of dressing yield, liver, gizzard, head and skin weight. Dressing percentage of broilers fed on HCl treated KSC at 2% level was significantly (P<0.05) lower compared to any other dietary treatment, whereas broilers in 2% KSC dietary group showed similar results to the control group. Percentage of head and skin weight relative to body weight were higher in treated (NaOH or HCl) KSC dietary group compared to either KSC alone or control group. However, the highest liver and gizzard weights were obtained from the broilers fed on diet containing 2% KSC treated with 1% HCl, followed by diet with 1% NaOH treated KSC, KSC alone diet and the control diet. The results of the present study clearly indicated that neither the 1% NaOH treated nor 1% HCl treated KSC alliviated the depressed productive performances and meat yield characteristics of broilers. It is concluded that the poor productive performances of broilers fed on KSC incorporated diet cannot be improved by treating KSC with either NaOH or HCl, and the oil extracted KSC may contain leftover oil which might have a potential toxic effect on growth and meat yield of broilers.Res.

Phytase is essential for enhancing nutritional value of feed and improving animal growthperformance and health. A study was conducted to evaluate the influence of Smartchoicephytase enzyme supplementation in the diet of starter broiler chickens. A total of 150 Rossstrain broiler chicks were used for the study and allotted to five treatment groups of 30 birdseach. Each group was further divided into three replicates of 10 birds per replicate. Five isonitrogenous(21.40% CP) and iso-caloric (2975.40 kcal/kg ME) dietary treatments werecompounded to contain 0g/100kg (T ), 10g/100kg (T ), 15g/100kg (T ), 20g/100kg (T ) and 1 2 3 425g/100kg (T ) of a commercial Smartchoice phytase enzyme preparation for 28 days in a 5Completely Randomized Design (CRD). Feed and water were provided to the chicks adlibitum.Daily feed intake and weekly body weight were measured. The result showed that thedaily feed intake and daily protein intake were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation. Final live weight, daily weight gain and total weight gain weresignificantly different among treatments. Protein efficiency ratio were significantly (P<0.05)higher in T (2.10) than T (1.80) but similar to T (2.05), T (2.05) and T (1.96). Feed 1 5 2 3 4conversion ratio was significantly (P<0.05) different in T5 (2.58) and T (2.02) but similar 1(P>0.05) in T (2.02), T (2.28), T (2.31) and T (2.38). Mortality was lowest in T5. Total feed 1 2 3 4cost per bird and daily feed cost per bird were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation while cost per kg of feed and daily feed cost per bird were notsignificantly (P>0.05) affected. The findings from this study showed that Smartchoicephytase enzyme could be supplemented up to 20g per 100kg in the diet of starter broilerchickens.

Poultry diets are largely composed of plant based materials that hold non-starch polysaccharides (NSP). The inclusion of NSP rich ingredients often reduces feed cost, but hampers a proper digestion due to anti-nutritional factors (ANF). Against this background, potency of exogenous enzymes was evaluated to upgrade dietary energy and total protein. A total of 180 broiler chickens were used in 28 days feeding trial. Six experimental diets were formulated in which maize based diet served as control (T1). Maize in the control diet was replaced by sorghum at the levels of 20% (T2), 40% (T3), 60% (T4), 80% (T5), and 100% (T6), respectively. Besides the control diet every other dietary groups were supplemented with enzyme at the rate of 50g/100kg. The broiler chicks were weighed and allotted to six dietary treatments of 30 birds each. The groups were replicated three times with 10 birds per replicate. The parameters determined for growth performance include: Final weight (g), Weight gain (g/bird), Daily weight gain (g/bird), Feed intake (g/bird), Daily feed intake (g/bird) and Feed conversion ratio (FCR). The result showed significant (p<0.05) effect on total feed intake and daily feed intake. Final weight, daily weight gain and feed conversion ratio (FCR) were not significantly (p>0.05) influenced by dietary treatments. Birds fed 60% (T4), 80% (T5) and 100% sorghum (T6) with enzyme supplementation showed higher similar statistical values 1365.00g, 1373.33g and 1373.66g, respectively for total feed intake. Haematological parameters were not significantly (p>0.05) affected by dietary treatments. Maize-sorghum based diet with enzyme supplementation had significant (p<0.05) effect on total protein, albumin and uric acid. Birds fed diets with 80% (T5) and 100% T6 sorghum levels with enzyme supplementation showed higher (p<0.05) statistical values 4.10 and 3.66 g/dl for total protein. Inclusion of sorghum up to 100% replacement level for maize with enzyme supplementation could be fed to starter broiler chicks for improved growth performance without adverse effect.

A feeding experiment was conducted to investigate the response of finishing broiler chicken to diets containing three metabolizable energy (ME)/crude protein (CP) combinations (3203.76 ME vs 19.90 %CP, 2884.15 ME vs 18.10 %CP and 2566.42 ME vs 18.10 %CP) at fixed ME:CP ratio of 160:1. A total of 126 four weeks old broiler chickens were randomly allotted to three dietary treatments replicated thrice. The final live weight, weight gain, feed intake, feed conversion and PER were generally higher in the birds fed the control diet (3203.76 ME vs 19.90 %CP). There were significant (P<0.05) differences among treatments in terms of final live weight, protein intake, energy intake, CP: Gain and ME:Gain, while weight gain, feed intake, feed conversion ratio and percentage mortality were statistically the same (P>0.05) across the treatments. Cost per kg feed decreased as the energy and the protein density of the diets decreased while the cost per kg weight gain decreased with increase in energy and protein density. The digestibility percentages showed a decreasing (P<0.05) trend while nitrogen retention increased with decrease in energy-protein density of the diets. Values for the haematological parameters and blood chemistry were significantly (P<0.01) higher in birds fed control diet and the values decreased with decreased levels of dietary energy and protein. The results suggest that when both energy and protein density of broiler finisher diet are reduced at fixed E:P ratio the feed intake would increase while the feed utilization efficiency decreases.

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

Abstract A total of 109 sows (Line 241; DNA, Columbus, NE) were used in a study to evaluate the effect of increasing phytase concentration in lactation diets on sow and litter performance. On d 107 of gestation, sows were blocked by body weight and parity and allotted to 1 of 3 dietary treatments of increasing phytase concentration (0, 1,000, or 3,000 FYT/kg; Ronozyme HiPhos 2700; DSM Nutritional Products, Inc., Parsippany, NJ). The control diet contained no phytase and was formulated to contain 0.50% standardized total tract digestible phosphorus (STTD P; 0.45% available P) and 0.62% STTD calcium (0.90% total Ca). The same STTD P and Ca concentrations were formulated for the phytase diets considering a release of 0.132 STTD P and 0.094 STTD Ca in both diets. Diets were fed from d 107 of gestation until weaning (d 18 ± 2). Litters were cross-fostered within treatment until 48 h post-farrowing to equalize litter size. Linear and quadratic response to phytase concentration was evaluated using the lmer function in R. There was no evidence for difference in sow body weight change, farrowing performance, wean-to-estrus interval, or litter size among dietary treatments. Sow average daily feed intake from farrowing to weaning tended to increase (linear, P=0.093) as phytase increased. Although not significant (linear, P =0.226), farrowing duration decreased as phytase increased. Litter weaning weight increased (quadratic, P=0.039) and overall litter gain increased (quadratic, P=0.047) with 1,000 FYT of phytase. In summary, sow feed intake tended to increase linearly with increasing phytase; however, feeding 1,000 FYT/kg maximized overall litter gain and weaning weight. This small-scale study suggests sow and litter performance benefits due to high inclusions of dietary phytase; however, a commercial trial with more sows is warranted to confirm these results.

An experiment was conducted to determine the influence of an acidifier as an alternative to antibiotics on the performance and gut morphology of broiler chickens. One hundred and eighty (180) 7-day old broiler chicks were randomly assigned to 3 dietary treatments of 4 replicates each. Each replicate had 15 birds. The diets fed to the birds were: Treatment 1- diet with neither antibiotic nor acidifier; Treatment 2- diet with antibiotic and Treatment 3- diet with acidifier. The antibiotic used was Enrofloxacin which was administered to the birds on Treatment 2 via their drinking water while the acidifier used was Biotronic SE (a combination of propionic and formic acids) which was added to the diet of birds on Treatment 3 at the rate of 4kg/tonne of feed. The experiment lasted 42 days. No significant differences were observed in the feed intake, final weight and weight gain of the birds on the different diets. Significant differences were however observed in the villus height in the duodenum and ileum of the birds. The crypt depth values in the different segments of the small intestines of the birds were not significantly affected by the different treatments.Key words: Organic acids, Biotronic SE, Enrofloxacin, Crypt, villus.
