SUMMARY This work evaluated the effect of including sweet potato meal (SPM), as an alternative to corn in broiler chicken diets, on performance, carcass yield, intestinal morphometry, organ biometry, meat quality and drumstick pigmentation. The study used 936 male Cobb-500 chicks. The experiment had a completely randomized, 3x2 factorial design, with three diet types. These included corn as the energetic ingredient in the standard diet (corn-soybean meal, CSM), and an increasing (ISP) and decreasing (DSP) inclusion of sweet potato meal as a corn substitute, in association with exogenous enzymes, for a total of six treatments with six repetitions and 26 birds per plot. During the period of 1 to 21 days, there was an interaction (P<0.05) for the weight gain (WG) variable; the CSM diets promoted greater WG in relation to the ISP and DSP groups, when supplemented with exogenous enzymes. There was an increase (P<0.05) in surface absorption of the jejunum villi and relative weight of the pancreas, and worse feed conversion (FC), for the ISP and DSP diets. With exception of the pancreas, for the entire period of 1 to 39 days the performance, yield of the carcass and cuts, meat quality, relative weight of the liver, and feet pigmentation variables were not affected (P>0.05) by the factors evaluated. Sweet potato meal, independent of the inclusion program (ISP/DSP) and enzyme supplementation, could partially substitute corn in broiler chicken feed, guaranteeing good performance, carcass yield and meat quality.

SUMMARY The aimed of the study was to evaluate the effect of the inclusion of different levels of an enzyme complex consisting of phytase, protease, xylanase, β-glucanase, cellulase, amylase, and pectinase on the parameters of performance, carcass yield and meat quality of broilers. Six hundred broiler chicks were used, and the animals were females with one day of age, from the Cobb 500 strain, and distributed in a completely randomized design, with five levels of inclusion of the enzyme complex (0, 100, 200, 300 and 400g/ton), and six repetitions, with twenty animals each. The weight gain, feed conversion ratio, feed intake and production viability were assessed in stages between 1 to 21, 1 to 35 and 1 to 42 days of age. The carcass yield and meat quality were evaluated at 35 and 42 days of age. We evaluated the characteristics of weight loss by cooking, shear force, water holding capacity, pH, lightness and color. The parameters of performance, carcass yield and carcass parts, and meat quality were not affected by the enzyme supplementation of diets fed to broiler chickens (P>0.05), except for the performance characteristics of the breast and the wings at 42 days of age (P<0.05).

This study was conducted to determine the effect of Ocimum gratissimum leaf meal supplementation on the performance, carcass characteristics and meat quality of broiler chicken. One hundred and fifty day old Abhor Acre strains of broiler birds were assigned to five dietary treatments with thirty birds per treatment in a completely randomized design. Ocimum gratissimum leaf meal at 0g, 100g, 200g, 300g and 400g per 100kg of feed was added to the diets. The experiment lasted for seven weeks. Data on feed intake, weight gain and feed conversion ratio were collected. Two birds per replicate were randomly selected, weighed, slaughtered and properly dressed for carcass parameters such as live weight, plucked weight, dressing percentage, head, neck, wing weight, thigh weight, drumstick, organ weight and sensory evaluation was carried out. The result of the performance characteristics showed that there were significant differences (p

Here we tested how feeding with exogenous enzymes affects the performance, carcass yield, and ileal digestibility in broilers from 21- to 42-days-old. The study included 1008 male broilers randomly distributed into six diets: positive control (PC), corn and soybean meal containing all the nutritional requirements; negative control (NC), with a 120 kcal.kg-1 reduction in metabolizable energy relative to the PC; enzyme complex one (NC + 100 ppm of endo-1,4-beta-xylanase); enzyme complex two (NC + 200 ppm of xylanase, amylase and protease); enzyme blend one (NC + 100 FXU kg-1 of xylanase and 200 FXU kg-1 of amylase); and enzyme blend two (NC + 100 FXU kg-1 of xylanase and 300 FXU kg-1 of amylase). The enzyme complex two (CN + 100 FXU.kg de xilanase e 300 FXU.kg de amilase) and enzyme blend two (NC + 100 FXU kg-1 of xylanase and 300 FXU kg-1 of amylase) had greater weight gain, feed conversion, carcass yield, and digestibility of nutrients than the NC (P < 0,05). We found that enzyme complex two and enzyme blend two valued their nutritional matrix promoting better performance and digestibility of broilers.

The objective of this study was to evaluate the inclusion of dry residue of cassava (DRC) with or without supplementation of carbohydrases on performance, carcass yield, cuts and organs, blood parameters and meat quality of broiler chickens. Birds were distributed in a completely randomised design in a 2 x 5 factorial scheme, with or without addition of carbohydrases and five levels of DRC inclusion, resulting in 10 treatments with 5 replicates of 22 birds each. At 21 days of age, two birds of each treatment were fasted for 6 hours for blood brachial puncture. At 42 days, four birds per pen were slaughtered to determine carcass yield, cuts, organs, percentage of abdominal fat and meat quality. Between 1-21 days of age, there was an interaction (P < 0.05) between carbohydrase and DRC supplementation on weight gain (WG) and feed intake, which showed a decreasing linear effect without the inclusion of carbohydrases. In the period from 1 to 42 days, there was an interaction (P < 0.05) between carbohydrase supplementation and DRC inclusion on the variables WG and feed conversion. Carbohydrase inclusion provided an increase (P < 0.05) in the concentrations of cholesterol, triglycerides, creatinine, gamma GT and blood glucose. Concentrations of gamma GT were increased and levels of alanine aminotransferase and creatinine were decreased (P < 0.05) with DRC inclusion. At 24 hours post mortem, there was a significant interaction (P < 0.05) for breast meat between carbohydrase supplementation and DRC inclusion for the variable L. The analysed values of pH, water holding capacity and shear force of the breast meat were not affected (P > 0.05) by DRC inclusion and carbohydrase addition. However, cooking loss was influenced (P < 0.05) by levels of inclusion of DRC. The L and a* variable and the feet of broiler chickens were not affected (P > 0.05) by DRC levels and carbohydrase addition. The colour variable b* showed a decrease (P < 0.05) from 5% level of inclusion. The results of this study show that DRC can be used in the diets of broiler chickens from 1 to 21 days old to the assessed level of 10%, provided that carbohydrase is added.

This article assessed the performance, carcass yield, and meat quality of finishing broilers fed increasing levels of hydroethanolic extract of guavira fruit peel (HEGP) were assessed. A total of 480, three-weeks-old male broilers were randomly allocated to dietary levels of HEGP (0, 100, 200, 300, 400, and 500 mg/kg), with five replicates and 16 birds each. There was a quadratic effect of HEGP inclusion on weight gain (WG) and feed conversion ratio (FCR), with the greatest WG and FCR being calculated at levels of 314 and 219 mg/kg HEGP, respectively. Broilers fed diets containing the extract had better performance than those fed an extract-free diet. There was no effect of extract inclusion on carcass yield and cuts. There was a quadratic effect of HEGP inclusion on a* (redness) of thigh meat at 15 min post-mortem, and on water-holding capacity (WHC), with the lowest and highest values being calculated at 270 mg/kg and 263 mg/kg HEGP, respectively. There was a quadratic influence of HEGP inclusion on the malonaldehyde content at 30-day storage, with highest value being calculated at 218 mg/kg HEGP. Dietary inclusion of 219 mg/kg of HEGP resulted in better FCR for broilers in the finishing phase but without improvement in meat quality.

Effect Of Feeding

An experiment was conducted to evaluate the comparative effect of feeding sundried sweet potato and its whole meal to weaner rabbits. The proximate analysis conducted revealed that sundried sweet potato meal and whole sundried sweet potato meal samples were rather low in protein contents as compared to maize. Twenty seven Weaner rabbits averaging 0.35kg were randomly allotted to 3 treatment groups in a completely randomized design. Each treatment group was replicated 3 times. Sundried Sweet potato meal and its whole meal replaced maize at 20% inclusion level. Treatments 1, 2, and 3 contained the control, sundried sweet potato meal (SSPM) and whole sundried sweet potato meal (WSSPM) respectively at 20% levels of inclusion. The weaner rabbits were fed ad-libitum throughout the experimental period. Significant differences (p<0.05) were observed for growth performance of the rabbits in average daily weight gain, average daily feed intake and feed conversion ratio in the weaner rabbits using sundried sweet potato and its whole meal. The values of mean daily weight gain ranged from 16.33g in treatment 2 (SSPM) to 18.47g in treatment 1 (control). Treatment 3 (WSSPM) gave a higher value that is comparable (p>0.05) to that of the control diet but better (p<0.05) than that of treatment 3 (SSPM). The values of average daily feed intake also ranged from 43g in treatment 2 (SSPM) to 50g in treatment 1 (control). WSSPM was consumed more than (p<0.05) than the SSPM which however influenced the cost of total feed consumed. Moreover, the values of feed conversion ratio (FCR) ranged from 2.54 in treatment 3 (WSSPM) to 2.70 in treatment 1 (control). Significant differences (p<0.05) were also observed in bio-economics of production of weaner rabbits using the test diets. The cost per kg feed, cost of total feed consumed per rabbit, cost per kg weight gain and revenue of the rabbits fed the test diets were significantly lower than the control diet however, the cost per kg weight gain was lower (p<0.05) for treatment 3 (WSSPM). For gross margin, WSSPM value was significantly higher (p<0.05) than SSPM value and the control diet. It was concluded that whole sundried sweet potato meal can be a good feed ingredient in rabbit diet.

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.

Metabolisable Energy

The objective of this study was to evaluate the effect of exogenous emulsifier and lipase in diets on performance, digestibility, and organ biometry of broiler chickens. A completely randomised design with seven treatments and seven replications was adopted. The treatments were as follows: T1 (positive control; PC): 3000, 3100, 3200, and 3250 Kcal of metabolisable energy (ME) kg-1 of diet for phases 1 to 10, 11 to 21, 22 to 31, and 32 to 37 days, respectively; T2: PC with reduction in ME of 30 Kcal kg-1 of diet; T3: PC with reduction in ME of 60 Kcal kg-1 of feed; T4 (negative control; NC): PC with reduction in ME of 90 Kcal kg-1 of feed; T5: NC with inclusion of exogenous lipase (10 000 U kg-1); T6: NC with inclusion of emulsifier (250 g t-1); and T7: NC with inclusion of lipase (10 000 U kg-1) and emulsifier (250 g t-1) in the period from 1 to 37 days of rearing. Performance characteristics (weight gain (WG), feed intake (FI), and feed conversion (FC)), carcass yield, cut yield, the relative weight of abdominal fat and organs (small intestine, liver, and pancreas), and relative intestinal length, in addition to dry matter digestibility (CDADM), ethereal extract (CDAEE), crude metabolisable energy (CMACE), and apparent metabolisable energy (AME) of the diets, were evaluated. In the initial phase, the CDAEE was higher for the PC group than for the emulsifier + lipase group. The AME determined in the final phase for the group supplemented with an emulsifier was higher by approximately 50 Kcal (EM) than the NC group. The WG of the lipase group was similar to that of the PC group. However, the groups with emulsifier and emulsifier + lipase showed a lower WG than the PC group. The additives used did not recover the FC to the same level observed in the PC group. The reduction in ME of 90 Kcal kg-1 generated a lower WG and worse FC. The use of both an emulsifier and lipase together produced results like to the PC group. The biometrics of the organs and the carcass yield and cuts were not influenced by diets. Thus, it can be concluded that the inclusion of lipase and an emulsifier improves the performance of broilers given diets with reduced energy, although it does not improve the lipid utilisation of the diets.
