Broiler Diet

This study was conducted to examine the effect of two humic substances (HS) supplemented in broilers’ diet on the breast meat quality of broiler chickens. In this experiment, 120 pieces of one-day-old COBB500 broiler chickens were used. Broilers were divided into three groups, each containing 40 birds with three replications (13, 13, and 14 per one pen). Fattening lasted 38 days. The first experimental diet was supplemented with 0.7% of HS (HS0.7) and the second was enriched with 0.7% of acidified HS (HSA0.7). The control group of broilers (C) was fed a basal diet without the addition of any supplements. HS0.7 samples had the highest total protein content and the lowest content of fat (p < 0.01). The effects of broiler diet and storage had a significant impact on the pH of breast samples, p < 0.001 and p < 0.05, respectively. Supplementation of HS in broiler diet positively affected the lipid oxidation of breast meat samples, as indicated by the lower malondialdehyde content (p < 0.05). HSA0.7 samples had significantly better juiciness after the storage period (p < 0.001). The quality of meat produced with supplementation of HS in broilers’ feed can be considered as valuable in human nutrition due to improved protein and fat content with decreased lipid oxidation.

Pozzo, L., Tarantola, M., Biasibetti, E., Capucchio, M. T., Pagella, M., Mellia, E., Bergagna, S., Gennero, M. S., Strazzullo, G. and Schiavone, A. 2013. Adverse effects in broiler chickens fed a high lycopene concentration supplemented diet. Can. J. Anim. Sci. 93: 231–241. The present investigation was designed to assess the effects of the administration of a high dietary lycopene dose to broiler chickens on growth and slaughter performances, haemato–biochemical parameters, antioxidant enzymes, histological lesions and lycopene accumulation in the tissues. Thirty-six 1-d-old male Hubbard broiler chicks were examined and divided randomly into two groups (three replicates for each dietary treatment): the Control group, which received a basal diet, and the Lycopene group, which received the basal diet supplemented with 500 mg lycopene kg−1diet. The experimental period lasted 35 d and growth performance was recorded on a weekly basis. At the end of the experiment (day 35), blood samples (n=12) were collected from the femoral vein. Erythrocyte and leukocyte numbers were assessed and the heterophil-to-lymphocyte ratio was determined. The alpha-1-acid glycoprotein, lysozyme, total protein and the electrophoretic patterns were evaluated in serum samples. Nine chickens per group were slaughtered to measure the carcass yields and the weight of the liver, spleen, bursa of Fabricius and thymus. Spleen, liver, and bursa of Fabricius samples were collected for histological examination and fixed in 10% neutral buffered formalin. The lycopene concentration, thiobarbituric acid reactive substances (TBARS) and chemical composition were assayed in breast meat and thigh samples. The TBARS, glutathione content, catalase and superoxide dismutase activity were measured in liver and kidney samples. The high lycopene concentration supplemented diet did not affect the birds’ growth, slaughter performance or antioxidant enzymes in the breast meat, thigh meat, liver and kidney samples. The concentrations of lycopene in the breast and thigh of the lycopene-supplemented group were 0.10±0.05 mg kg−1and 0.42±0.35 mg kg−1, respectively, while no lycopene was found in the Control group. Spleen and bursa of Fabricius of birds fed a diet supplemented with a high level of lycopene showed weight decrease (P<0.05) and degenerative lesions (P<0.05). Moreover, lycopene supplementation reduced the serum protein concentration, albumin, alpha and the gamma globulin serum concentration (P<0.05).

Abstract Background: With increasing of duck meat among consumers, the demand for growth performance and the meat quality health of ducks in increasing. Dietary curcumin altered the growth performance and meat quality. However, study on the effect of dietary curcumin on the growth performance, serum antioxidation and meat quality of ducks. This study invested effects of dietary curcumin given to ducks on the growth performance, antioxidation capacity in plasma, meat quality, lipid oxidation and the concentration of volatile compounds in duck breast muscle. A total of 600 healthy ducks with similar body weight were randomly allotted into 4 groups with 10 replicates per group and 15 ducks per replicate. Ducks were fed experimental diets which the curcumin supplemental levels were 0, 300, 400 and 500 mg curcumin/kg basic fed, respectively. The experiment lasted for 10 weeks. Results: Results showed that dietary supplementation of curcumin at levels 300, 400 and 500 mg/kg dietary (P < 0.05) improved the average final body weight. The ducks fed the basal diet without curcumin supplementation had the lowest FI (P > 0.05) and highest FCR (P > 0.05) among all ducks. Feeding ducks on diets supplemented with curcumin at each level significantly increased (P < 0.05) plasma activity of T-SOD and GSH-Px, and significantly reduced plasma MDA concentration compared to the control group. The dietary curcumin significantly increased the growth performance and the antioxidation capacity in plasma of ducks. Dietary curcumin improved the meat quality of ducks by significantly increasing pH45, pH24 (P < 0.05) and color of duck meat (P < 0.05), and significantly decreasing cooking loss (P < 0.05), shear force (P < 0.05), and the lipid oxidation of duck meat. 56 volatile compounds were identified and quantified. Interestingly, cantharidin among volatile compounds was firstly found in duck muscle, and only existed in the group of 500 mg curcumin/kg diet. Conclusions: In conclusion, the supplementation of duck diets with curcumin at 300, 400, and 500 mg/kg diet improved growth performance, antioxidant status and meat quality of ducks. The cantharidin was firstly found in duck breast muscle when the dietary curcumin inclusion of 500 mg/kg.

Glutinous Rice

This study investigated the effect of purple glutinous rice bran (PRB) supplementation on performance, oxidative status and lipid oxidation in broiler. Two hundred male day old broiler chickens were randomly assigned to 5 groups of 40 birds each. Each treatment, fed the basal corn-soybean diets containing 0%, 3%, 6%, 9% and 12% of purple glutinous rice bran (PRB). Diets were formulated separately for starter and finisher phases (day 0 to 21 and day 22 to 42). Oxygen radical absorbance capacity (ORAC) in PRB supplemented groups were higher than rice bran group and depend on the supplement dose of PRB. PRB supplementation (6%, 9% and 12%) increased (P less than 0.05) weight gain (WG), average daily gain (ADG) and decreased (p less than 0.05) feed conversion ratio (FCR) compared to control group. Malondialdehyde (MDA) levels in serum from the PRB groups were lower than control group (P less than 0.05). Glutathione (GSH) levels in serum of PRB groups (6%, 9% and 12% PRB) were higher than control group (P less than 0.05). However, there were no difference between 3% PRB and control groups. No difference of lipid oxidation in breast meat after storage between PRB supplemented groups with control group (P>0.05). This study indicated that PRB supplementation in diet had positive effects on performance and oxidative status of broiler chickens but had no effect on lipid oxidation in breast meat storage

The experiment was conducted to determine the effects of broiler chickens dietary kaolin, bentonite and zeolite supplementations on broiler thigh meat water holding capacity (WHC), lipid oxidation (TBARS), pH, and meat color during frozen storage. A total of 448-dayold sexed broiler cockerels were randomly assigned into 28 experimental units. A cornsoybean meal basal diet with 0, 15 and 30 g/kg kaolin, bentonite and zeolite as feed additive were added to control and 6 dietary treatments. Chickens were slaughtered and the left thighs kept at −20°C and analyzed after 1 and 150 days of storage. Experimental treatments had no effect on meat WHC, pH and color. Freezing at −20°C for 150 days impaired meat quality and caused chicken rancidity; however, lipid oxidation measured by TBARS value was significantly lower in chickens received diets including 15 g/kg bentonite and kaolin comparing to control diet after 150 days of frozen storage (P&lt;0.05). It was concluded that though adding silicate minerals did not significantly influence WHC, pH and color in experimental treatments, they had influenced lipid oxidation and decreased chicken meat rancidity during frozen storage period

The aim of the study was to determine the effect of different levels of DL-methionine in feed for broiler chickens on the quality of vacuum-packed breast muscles stored under refrigeration. The material for the study was 72 breast muscles from 35-day-old broiler chickens fed diets with varying content of DL-methionine. The control group received a basal diet without additional DL-methionine, while the experimental groups received compound feeds supplemented with 0.08% or 0.24% DL-methionine. At 35 days of age, 24 birds from each group were randomly selected and experimentally slaughtered. After the carcasses were dissected, 8 right breast muscles were selected from each feeding group and analysed immediately after cooling. The remaining muscles were vacuum-packed and after 7 and 14 days of storage physicochemical and sensory analyses were performed to assess the influence of storage time on changes in their quality. The methionine level was not found to affect the sensory properties of the breast muscles, but the meat of birds receiving a higher level of this amino acid had better shear force and water-holding capacity in comparison to the control group. After just 7 days, the results of the analyses of vacuum-packed refrigerated muscles showed a negative effect of storage time on the capacity of the muscle tissue to bind water, as well as changes in the proportion of red colour in the muscles. However, it is worth noting that the sensory quality of the muscles deteriorated only after 14 days of storage.

Cornelian Cherry

The use of natural plant extracts in poultry feed could improve their productivity as well as the oxidative stability of stored derived meat. The roles of cornelian cherry extract (CCE) in growth, cecal microbes, and meat antioxidative markers of broiler chickens were evaluated. A total of 500 Ross 308 broiler chicks were fed diets supplemented with CCE (0, 50, 100, 200, 400 mg/kg of diet) for 38 days. The highest levels of weight gain and feed utilization were observed in a group fed 200 mg/kg of CCE. Maximum upregulation of glucose transporters—1 and 2 and sodium-dependent glucose transporter genes—were found in the group fed 200 mg/kg of CCE. Lactobacilli and Bifidobacterium colonization increased as the CCE levels increased. The greatest upregulation of antioxidant genes (glutathione peroxidase, catalase, and superoxide dismutase) in breast meat was observed in groups fed CCE (200 and 400 mg/kg). Dietary CCE significantly delayed the lipid oxidation of breast meat compared with that of the control group. The total phenolic content, 2,2-Diphenyl-1-Picrihydrzyl (DPPH) radical scavenging activity and reducing power in meat improved with higher levels of CCE. Dietary CCE improved the growth, performance of broilers, and meat antioxidant stability after 90 days of storage.

AbstractThe primary aim of this study was to investigate the impact of three dietary levels of lactose (LAC) originating from conventional dried whey (DW) and the duration of these treatments (from 8 to 21 or to 42 days of age) on growth performance, basic post-slaughter traits and excreta quality of broiler chickens kept in cages. A secondary purpose was to investigate the effect of LAC level on some parameters of the caecal micro-environment and gross morphology in these birds. A total of 560 Ross 308 chickens (sex ratio 1:1) were assigned to 7 dietary combinations with 10 replicate cages of 8 birds per cage. The control group was fed basal diets consisting of maize, wheat and soybean meal. The other 6 groups received the same basal diets with DW added in amounts equivalent to a LAC dietary levels of 1, 2 or 3%. Only continuous feeding (day 8 to 42) with 1% and 2% levels of LAC was found to yield the overall body weight gain (BWG) during the whole 42-day rearing period, which was significantly higher than that on the control diet, with a larger share of breast meat in carcass at a 2% LAC. However, these effects were associated with greater faecal score values indicating more watery excreta compared with the control. Increasing levels of LAC augmented the relative caecal weight and length. A reduction in the caecal pH was confirmed at day 21 for birds fed 1% and 2% of dietary LAC. The lower pH values were correlated to an increased sum of total volatile fatty acids (VFA), causing large increases in the concentration of undissociated forms of individual VFA. The decline in plate counts of coliform bacteria was observed with 2% and 3% LAC, whereas the counts of lactic acid-producing bacteria (LAB) were higher at these two LAC levels. The present findings lead to the conclusion that the dietary level of 2% LAC originated from DW is the most effective in enhancing the productivity of broilers, with moderate occurrence of undesirable side effects.

Abstract The objective of this work was to evaluate the effect of the use of hybrid phytase, alone or combined with carbohydrases, in poultry diets with nutritional reductions of calcium, available phosphorus, and metabolizable energy on the nutrient digestibility and bone quality of broiler chickens. A total of 1,875 broilers were distributed in five treatments in a completely randomized design, with 15 replicates of 25 chickens each. The treatments consisted of a positive control feed (T1) and of four negative controls (T2 to T5): T1, basal diet (BD) with corn and soybean; T2 and T3, BDs with reductions of 70 and 100 kcal kg-1 metabolizable energy, respectively, and both with reductions of 0.16% Ca and 0.15% available P; and T4 and T5, BDs with the same nutritional reductions, but supplemented with enzymes, i.e., T4 = T2 + 500 phytase units (FTU) per kilogram and T5 = T3 + 500 FTU kg-1 + 560 xylanase units (TXU) per kilogram + 250 glucanase units (TGU) per kilogram. The use of 500 FTU kg-1 hybrid phytase in pelleted corn-soybean meal diets allows a good digestive performance by broilers and replaces the nitrogen-corrected apparent metabolizable energy at 70 kcal kg-1, as well as 0.16% Ca and 0.15% available P.

For determination of poultry quality shortly after slaughtering, physical criteria (pH-value, conductivity, colour, juice retention) are of importance. However, they are affected by breeding, transport, cooling and the storage period. PH-values of breast meat (genetically structured material) were recorded shortly after slaughtering (15 min p.m.) and differences between breeding line and gender were found (n=5109). The pH1-values ranged from 5.50 to 6.79. Male broilers showed significantly lower pH1-values than female ones (6.02:6.10). There were also significant differences concerning breeding line and gender. Meat quality (PSE, DFD) of broilers can be recorded quickly and accurately determining the pH1-value of breast meat. Threshold ranges to be considered are ? 5.8 (PSE), 5.9-6.2 (standard meat properties) and ? 6.3 (DFD). This classification is not to be compared to the deviation of pork.
