This study was conducted to determine the optimum dietary glycine equivalent (Glyequi) level in low crude protein (LCP) diets of 181 g/kg containing varied concentrations of standardized ileal digestible (SID) methionine+cysteine (Met+Cys) for broiler chicks (1-21d old). A total of 1275, 1-d-old Cobb-Vantress® male broilers were distributed in a 5 × 3 factorial arrangement of completely randomized design of 15 treatments with five replicates of 17 birds each. Treatments consisted of 5 levels of dietary Glyequi (14.9, 16.4, 17.9, 19.4 and 20.6 g/kg) and three concentrations of SID Met+Cys (7.70, 9.0 and 10.3 g/kg). Interactions between Glyequi and SID Met+Cys levels were observed for feed:gain (P = 0.055) and breast meat yield (BMY) (P = 0.017). In 7.7 and 9.0 g SID Met+Cys/kg diets, optimal feed:gain and increased BMY were observed at the Glyequi level not lower than 17.9 g/kg. In 10.3 g SID Met+Cys/kg diet, a lower feed:gain was achieved at 19.4 g Glyequi/kg. Therefore, a minimum dietary level of 17.9 g Glyequi/kg is needed to increase growth of broilers fed diets containing 7.7 or 9.0 g/kg SID Met+Cys while 19.4 g/kg Glyequi is necessary in diets containing 10.3 g/kg SID Met+Cys for optimum growth.

ABSTRACT The objective of this study was to evaluate the effects of probiotics and synbiotics on the performance and Enterobacteriaceae count of broiler chickens. A total of 640 one-day-old male broiler chicks were distributed in a completely randomized design with four treatments and eight replicates with 20 birds each. The treatments were: ration with performance enhancer (zinc bacitracin; positive control); ration without performance enhancer and probiotic/synbiotic (negative control); ration with probiotics; and ration with synbiotics. At 35 days, five birds from each treatment were euthanized and intestinal contents were harvested for determining the Enterobacteriaceae count. The performance data and average colony-forming units (CFUs) transformed as log CFU/g were subjected to analysis of variance and Tukey’s test. The effects of probiotics and synbiotics were observed in the initial phase, with supplemented birds exhibiting comparable weight gain to those supplemented with bacitracin. No effect of the treatment on broiler performance was observed after 42 days. The enterobacterial count was comparable among all experimental treatments. Supplementation with probiotics and synbiotics did not compromise the performance of broilers and did not alter the Enterobacteriaceae count.

Abstract. This study aimed to evaluate the effect of multienzyme+probiotic (MEP) supplementation on carcass characteristics and serum biochemistry of broiler chickens fed fermented shea butter cake meal (FSBCM) based diets. A total of two hundred and sixty (260), 28-day-old broiler chicks were distributed into four treatments, with five replicates of 13 birds each using a completely randomized design and reared on deep litter system from 28 to 56 days of age. The four treatments were: positive control – T1 (corn-soybean based diet); negative control – T2 (20% FSBCM replacement for corn in T1); diet 3 – T3 (T2 diet + 0.05% MEP) and diet 4 – T4 (T2 diet + 0.10% MEP). On day 56, two birds per each pen were selected for carcass and organ evaluation and other two birds per replicate were selected for serum biochemical analysis. The results indicated that addition of MEP to FSBCM diet caused a significant (p<0.05) increase in live weight, dressing percentage and breast meat yield than FSBCM diet without MEP and did not differ from the T1 diet. The abdominal fat in birds fed MEP treated diets were significantly (p<0.05) lower than those groups fed PC and FSBCM diets. Serum glucose was similar (p>0.05) between birds fed PC and MEP treated diets but significantly (p<0.05) higher than those on FSBCM diet, whereas serum cholesterol, alanine aminotransferase and aspartate aminotransferase concentrations reduced significantly (p<0.05) in groups fed MEP supplemented FSBCM diets. All other parameters were not significantly (p>0.05) affected by the MEP supplementation. Therefore, MEP supplementation in FSBCM based diet improved live weights and carcass attributes without any detrimental effect on blood composition of the broiler chickens.

The effect of phytobiotics inclusion on haematological and serum indices of broiler chickens was investigated using 180 one day-old Arbor-acre broiler chicks in an eight weeks feeding trial. Six experimental diets were formulated to include the control diets (Og/kg), Ginger (5g/kg), Pawpaw leaf (5g/kg), Moringa (5g/kg), Turmeric(1g/kg) and Oxytetracycline (0.5g/kg) diet. These diets were assigned to six groups of 30 chicks replicated 3 times with 10 birds per replicate in a completely randomized design (CRD). Feed and water were given ad libitum. At the end of eight weeks, blood samples were collected from jugular vein of the birds and were analyzed for haematological and serum biochemical indices. The result of the analysis showed that dietary treatments significantly (p<0.05) influenced all haematological parameters studied. Ginger had the highest value of packed cell volume (45%), haemoglobin (15.05 g/dl) and red blood cell count (3.39x1012L-1) at the finisher phase. Total protein, uric acid, glucose were significant (p<0.05). Serum cholesterol value was significantly (p<0.05) lower in birds supplemented with ginger compared to other groups. It can be concluded that ginger at 5g/kg improved PCV, Hb and reduction of cholesterol concentration in broiler chicken.

Different Levels

Different levels of synthetic lysine amino acid were supplemented to 240 starter broiler chicks randomly distributed to 12 groups of each 20-day chicks and allocated to four treatment diets in a Completely Randomized Design (CRD). T1 (Control) basal diet (0% synthetic lysine); T2 (0.15% synthetic lysine); T3 (0.3% synthetic lysine) and T4 (0.45% synthetic lysine). There was no significant difference (P>0.05) observed between treatments in dry matter, metabolizable energy, crude protein intake, body weight and death rate of the chicks. In conclusion, there were no significant changes for all parameters and further amino acid analysis of the feedstuffs is required and extra addition above 0.45% synthetic lysine of T4 need to be added in this experiment which numerically improved the chick’s performance. Further experiments were recommended to evaluate the levels of lysine amino acid in the feedstuffs and its inclusion level in to the diet of modern broiler strains.

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 An experiment was conducted to evaluate broiler chicken performance and carcass yield in response to carbohydrase supplementation (Xylanase and Betaglucanase; XB) and association of carbohydrase and phytase (PHY). A total of 1,920 day-old male broiler chicks (Cobb 500) were distributed in a completely randomized design with 8 treatments and 8 replicates each, allocated in 64 pens with 30 chicks each. The treatments were: Positive Control (PC); Negative Control (NC): reduced ME [-120kcal/kg (Starter) and -170kcal/kg (Finisher)]; NC + XB [50g/ton]; NC + XB [100g/ton]; NC + XB [150g/ton]; NC + XB [50g/ton] + PHY [100g/ton]; NC + XB [100g/ton] + PHY [100g/ton]; NC + XB [150g/ton] + PHY [100g/ton]. The inclusion of XB (150) and XB (50, 100, and 150) associated with phytase increased feed intake than positive control when considering the total rearing phase. The feed conversion ratio of all broilers fed diets with energy reduction were worse than positive control, even with the addition of enzymes, and did not differ between them. There was no significant effect of treatments on carcass parameters.

The study was conducted with an aim to investigate the effect of litter density on growth, leg health and litter quality of broiler chickens from d1-42 days. Day-old male broiler chicks (n=400; Cobb 500) were distributed randomly into four litter densities [T1, T2, T3 and T4] treatments, each treatment had 5 replicates with 20 birds per replicate cage in a completely randomized design. Wood shaving was used as litter materials to a thickness of 5 cm, 8 cm, 11 cm and 14 cm on the floor of the pen. Birds were reared on the litter floor open-sided housing condition with ad libitum feed and water throughout the trail period. Data on feed intake (FI), body weight (BW), feed conversion ratio (FCR) and mortality were measured weekly. Litter sample was collected on day 42 to assess the nitrogen content (N2 %), dry matter (DM%) and moisture level (%). Footpad dermatitis (FPD) and hock burn (HB) incidences were measured on day 42 to assess the leg quality of birds. Results demonstrated that litter thickness had no significant (P>0.05) effect on FI, BW, FCR and mortality of broilers from d1-42 days. The N2, DM or moisture levels (%) of litter were also unaffected (P>0.05) between treatment. Leg disorders such as HB and FPD were influenced (P<0.01) by treatment. The incidences of HB and FPD were higher (P<0.01) in T1 and T2 than other treatments. It can be inferred from our current study that, leg health may be deteriorated by using low density wood shaving without affecting growth and litter quality of broiler chickens. Bang. J. Anim.

This study aimed to assess the effect of different breeds and crosses of broiler chickens and sex on growth, carcass characteristics, and tissue composition. The experimental design was a completely randomized design in a 6 × 2 factorial scheme, with six genotypes (New Hampshire – NHS, Jersey Black Giant – JBG, Rodhe Island Red – RIR, Indigenous Giant – IG, and the hybrids IG × NHS and IG × JBG) and two sexes (male and female). Each treatment was composed of five replications with three broiler chickens, totaling 180 broiler chickens. Zootechnical performance and growth were assessed through the Gompertz equation parameters. After slaughtering at 105 days, the characteristics of carcass and main cuts were determined by means of weight, yield, and proportion of tissue constituents (meat, bone, and skin). Regarding the Gompertz equation parameters, the genotype NHS presented a higher growth potential. Males presented higher live weight and carcass weights, except for IG. No difference was observed between genotypes and sexes (P > 0.05) for carcass yield. The genotype JBG presented the highest average for breast yield (24.4%). Males presented the highest average for leg yield (30.5%). The genotype IG presented the highest value of breast meat yield (71.2%), being similar to the genotypes from the crosses IG × NHS, and IG × JBG (68.9 and 68.3%, respectively). For meat to breastbone ratio, the genotype IG presented the highest value (3.4) and, considering the sex, females presented a higher average (3.2) for this characteristic. Regarding the proportion of leg meat, an effect was observed for genotype and sex (P < 0.05) with the highest values observed for the hybrid IG × JBG and females (66.3 and 66.0%, respectively). For meat to leg bone ratio, the genotypes NHS, JBG, RIR, and IG × NHS presented the highest values (2.6, 2.7, 2.6, and 2.6, respectively), with females presenting the highest value (P < 0.05) (2.7). The genotypes IG, IG × NHS and IG × JBG presented the best growth and carcass characteristics, being recommended to be reared under an alternative system. Females presented the highest breast yield and, proportionally, the highest amount of leg meat, which are important attributes in a chicken meat production system.

A 28-day feeding trial was conducted to determine the effects of dietary inclusion of Mucuna seeds: soaked in Calcium hydroxide (Ca(OH)2) solution, soaked in Ca(OH)2 and cracked water-soaked and cooked, on the performance of broiler chicks. Two batches of raw Mucuna seeds were used. The first batch was soaked in 3% Ca(OH)2 for 48 hours. Part of the soaked seeds were sun-dried and milled. The remaining part were cooked, sun-dried and milled. The second batch was cracked, soaked in water for 48 hours and cooked before sun drying and milling. Both meals were analyzed for their proximate composition and included in broiler starter diets at 20% dietary level respectively. The control diet contained no mucuna meal. Each diet was fed to a group of 40 broiler chicks in a completely randomized design replicated four times. At 20% dietary level containing Ca(OH)2 soaked seed meal significantly (P<0.05) depressed the performance of the birds in terms of feed intake, growth rate and feed conversion ratio. However, soaking in Ca(OH)2, prior to cooking and cracking prior to soaking in water and cooking did not adversely affect the performance of the birds in all parameters measured.
