AbstractA feeding trial was conducted to evaluate the effects of plant extracts derived from Mentha arvensis (MA) and Geranium thunbergii (GT) on broiler performance, carcass yield, digestive organ weights, meat quality and odorous gas emissions from the excreta. A total of 210 one-day-old broiler chicks were randomly assigned to one of the following dietary treatments for five weeks: (1) control, (2) 0.1% MA, (3) 0.05% GT, (4) 0.1% GT and 0.1% mixed preparation with varying ratios such as (5) 0.1% 1MA:1GT, (6) 0.1% 1MA:4GT and (7) 0.1% 4MA:1GT. The weight gain (0–3 weeks) was significantly (P<0.01) increased in response to dietary inclusion of plant extracts; however, no significant differences were observed in breast and thigh meat yield (P>0.05). Additionally, no differences were observed in proventriculus, gizzard, pancreas, small and large intestine weight. When compared with the control group, birds fed plant extracts had the lowest meat TBARS value after 0 and 3 weeks of storage (P<0.05). Moreover, the pH value was significantly lower (P<0.05) in the plant extract supplemented groups at 0 weeks. The faecal H2S emissions were significantly reduced at 0 h and 6 h in all supplemented groups relative to the control (P<0.05). Similarly, NH3 emissions were reduced at 0 h and 6 h for all supplemented groups except the 0.1% 1MA:1GT group (P<0.05). Overall, the results of the present study indicate that plant extracts supplementation can be used to improve performance and meat quality of broiler chickens while reducing the emission of harmful gases from the excreta.

Background: In Vietnam, animal feed mainly depends on imported raw materials, while available agro-industrial by-products are often released into the environment and only a its unsubstantial portion used as an animal feed. Therefore, efficient use of these by-products as animal feed is essential. This work aimed to evaluate the effect of dietary levels of rice distiller’s dried grain (Rice DDG) on broiler performance, meat yield and meat quality. Methods: The research was conducted at the experimental station, Vietnam National University of Agriculture, Vietnam, from May to September 2020. A total of 240 a day-old broiler chicks were randomly assigned into 4 groups with 3 replications to receive 4 diets with different levels of RDDG at 0, 5, 8 and 10% for 14 weeks. Growth, meat yield and meat quality were estimated. Result: ADG was higher in broiler chickens fed diets with rice DDG compared to that in control diet at 12 and 14 weeks (P less than 0.05) while ADFI and FCR were not affected by the diets. There were significantly no differences in meat yield and quality among the diets. In conclusion, rice DDG could be used to partially replace main ingredients in chicken diets.

A feeding trial was conducted by supplementing Mentha arvensis (MA), Geranium thunbergii (GT) and liquid minerals (LM) in drinking water of pigs and the effects on growth, carcass characteristics and meat quality were evaluated. A total of 80 pigs were allocated into 4 treatments: control (0% plant extracts, 0% LM), T1 (0.1% LM + 0.1% 1 MA: 4 GT), T2 (0.1% LM + 0.1% 4 MA:1 GT), T3 (0.1 % LM + 0.1% 1 MA:1 GT). Weight gain was significantly increased in T3. However, the dietary treatments had no significant effect on carcass weight, back fat thickness and water holding capacity (WHC). A significant reduction in cooking loss and shear force was observed in T2. Considering the meat color, T3 significantly increased the a* value. Microbial count was significantly decreased (P less than 0.05) at 0-week of storage in T3. Our studies indicate that plant extracts and liquid minerals enhances the growth performance and meat quality, without any adverse effects.

This experiment was designed to determine the meat quality and lipid profile of broiler chickens fed diets containing turmeric (Curcuma longa) powder (Tur) and cayenne pepper (Capsicum frutescens) powder (Cay) as antioxidants. Two hundred and forty three (two-week old) Abor Acre broiler chicks were randomly allotted to nine treatment groups of 27 birds each, consisting of three replicates of nine birds each in a completely randomised design. Three levels of Tur (0, 2 and 4 g/kg) and three levels of Cay (0, 1 and 2 g/kg) were used to provide nine dietary treatments.  Meat quality indices such as cook and refrigerated losses, water absorptive power, etc were measured and determined at the 8th week. Broiler Chickens fed the basal diet had highest meat dry matter, protein content and least (p<0.05) meat pH, cook and refrigeration loss values. Meat triglyceride and meat malondialdehyde value was best (p<0.05) in treatments fed dietary 2 g/kg Cay, while chickens fed 2 g/kg Cay, 2 g/kg Tur + 1 g/kg Cay and 2 g/kg Tur + 2 g/kg Cay had better meat lipoprotein values. For meat sensory characteristic, meat flavour of broiler chickens fed diets containing 2 and 4 g/kg dietary Tur, were  moderately liked while overall flavour was best (p<0.05) in groups fed the basal diet with no dietary additive. It was evident in the study that the dietary inclusions of the test ingredients limited lipid oxidation, thus improved storage duration and meat flavor.

In this study, it was aimed to determine the performances and some carcass and small intestine properties of broiler chickens fed diets in which sunflower meal (SFM) replaced soybean meal (SBM) and supplemented or not with multi-enzyme. With this aim, a total of 450 1-day-old age mixed-sex Ross 308 broiler chicks were used in a completely randomized design, with five treatments and three replicates of thirty birds each. The experimental diets consisted of a control group and two levels of SFM with or without enzyme replacing 50 or 100% of SBM protein, respectively. Hence, treatment groups were: control (100SBM), 50SFM, 100SFM, 50SFME, and 100SFME). Feed and fresh water was given freely. At the end of the experiment (42 days of age), 100SBM broilers had higher body weight and cold carcass weight than all other groups (P is less than 0.05) and had lower feed conversion ratio (FCR) compared to 50SFME broilers (P less than 0.05). Feed consumption, weights of hearth, liver, gizzard, abdominal fat and small intestine and length of small intestine were not found different among the groups (P is less than0.05). Our observations demostrated that addition of the 0.05% multi-enzyme mixture into SFM diets of broiler chickens had not positive impact on the availability of SFM and broiler performance

The present study aimed to investigate the effects of dietary supplementation with powdered peanut skin (PS) as natural antioxidant and growth promoter on growth performance, carcass characteristics, serum metabolites and meat quality of Cobb broiler chickens. A total of 240 unsexed Cobb 500 1-week-old broiler chicks were randomly assigned to four treatment groups with six replicates. The dietary treatments consisted of the basal diet as control and PS groups (1.0, 2.0, and 3.0 PS g/kg). Results showed that the highest values (P < 0.01) of live bodyweight and bodyweight gain were observed in the control group at 3 weeks of age and during the period of 1–3 weeks of age, respectively compared with all levels of PS. During 1–3 weeks of age, feed intake per day chicks fed the diet containing PS levels decreased numerically (P > 0.01) with increased levels of PS compared with the control. Supplementing 1.0 or 3.0 g/kg of PS insignificantly enhanced feed conversion ratio at 1–6 weeks of age. Dietary treatments significantly depressed giblets (P = 0.002), thigh (P = 0.0.027) and abdominal fat percentages (P > 0.0.1), however, increased (P = 0.004) breast percentage of broiler chicks at 6 weeks of age. The lowest value of serum creatinine and urea achieved by chicks fed diet contained 3.0 PS g/kg diet. Also, high density lipoprotein cholesterol in addition to triglycerides were significantly (P < 0.05 and P < 0.01) decreased with increasing level of PS supplementation. It can be concluded that PS as a phytogenic additive could be used as a supplementation to broiler diets to lower abdominal fat in carcass and cholesterol, creatinin and urea in blood. Sensory characteristics were not affected except that appearance was improved. Water-holding capacity was also improved.

Deficit of conventional feed ingredients in meeting increased demand has led to an alarming hike in their prices culminating in sky rocketing cost of livestock feed. This has necessitated an urgent search for low cost and more readily available alternatives. This study was conducted to investigate the performance of broiler chicks fed diets containing graded levels of soaked and boiled Bambara nut seed meal (BNSM). One hundred and five (105), 2 week old broiler starter chicks were used for the experiment. The birds were randomly allotted into four dietary treatments with each treatments replicated thrice at seven birds per replicate in a completely randomized design. Five experimental diets were formulated containing processed BNSM designated as T1 (control diet with 0 % BNSM), while T2, T3, T4 and T5 had 5 % soaked BNSM, 10 % soaked BNSM, 5 % boiled BNSM and 10 % boiled BNSM, respectively. The experiment lasted for four (4) weeks. Feed and water were provided ad libitum. The results showed that birds fed processed BNSM diets had significantly (P<0.05) higher final weight and weight gain comparable to 702.38g and 19.99 g/bird/day in the control group. The values obtained from feed intake showed that T2 (64.74 g) had significantly (P<0.05) least value compared to other dietary treatments. Feed conversion ratio and feed cost per kg gain (N) were significantly (P<0.05) better in birds fed processed BNSM diets compared to 3.39 and N215.85 respectively in the control group. It was therefore concluded that processed BNSM improved performance of broiler chickens.     Le déficit d'ingrédients alimentaires conventionnels pour répondre à la demande accrue a conduit à une hausse alarmante de leurs prix, aboutissant à une flambée du coût des aliments pour le bétail. Cela a nécessité une recherche urgente d'alternatives peu coûteuses et plus facilement disponibles. Cette étude a été menée pour étudier la performance des poussins de départ de pouletsde chair nourris avec des régimes contenant des niveaux échelonnés de farine de graines de noix de Bambara trempées et bouillies. Cent cinq (105) poussins de départ âgés de 2 semaines ont été utilisés pour l'expérience. Les oiseaux ont été répartis au hasard en quatre traitements diététiques, chaque traitement étant répliqué trois fois à raison de sept oiseaux par réplique dans une conception complètement aléatoire. Cinq régimes expérimentaux ont été formulés contenant du 'BNSM'-Bambara nutseedmeal(Aliment de farine de graines de noix de bambara)- traité désigné comme T1 (régime témoin avec 0% de BNSM), tandis que T2, T3, T4 et T5 contenaient 5% de 'BNSM' imbibé, 10% de 'BNSM' imbibé, 5% de 'BNSM' bouilli et 10% de 'BNSM' bouilli, respectivement. L'expérience a duré quatre (4) semaines. L'alimentation et l'eau étaient fournies ad libitum. Les resultants ontmontré que les oiseaux nourris avec des régimes 'BNSM' transformés avaient un poids final et un gain de poids significativement plus élevés (P <0.05) comparables à 702.38 g et 19.99 g / oiseau / jour dans le groupe témoin. Les valeurs obtenues à partir de la consommation alimentaire ont montré que T2 (64.74 g) avait une valeur significativement moindre (P <0.05) par rapport aux autres traitements diététiques. Le taux de conversion alimentaire et le coût alimentaire par kg de gain (N) étaient significativement meilleurs (P <0.05) chez les oiseaux nourris avec des régimes 'BNSM' transformés par rapport à 3.39 et N215.85 respectivement dans le groupe témoin. Il a donc été conclu que le 'BNSM' transformé améliorait les performances despoussins de départ de poulets de chair.

The emergence of antibiotic-resistant bacteria in the intestinal microbiota of broiler chickens, and the possibility of antibiotic residues in meat and meat products are seen as a threat to animal and human health. The search for alternatives to conventional drugs, including natural compounds, is an interesting approach to prevent the adverse effects of antibiotics. Therefore, the aim of the present study was to evaluate whether the addition of tannin (as a quebracho extract) in the diet of broiler chickens could be used to replace in-feed antimicrobials and coccidiostatic drugs, to exert positive effects on animal health and performance. The use of tannin in the diet of broiler chicks as an additive (at 0.5% for 1–10-day-old birds; and 1.0% for 11–42-day-old broiler chickens) enhanced their bodyweight, weight gain and daily weight gain on Day 42 of life, compared with the untreated control group (P &lt; 0.05). However, these findings were not observed when tannin was added at 0.5%. Moreover, broiler chickens fed with an extract containing tannins showed higher erythrocyte counts, as well as haemoglobin and haematocrit concentrations than did those in the control group, whereas counts of total leukocytes and lymphocytes were lower (P &lt; 0.05). The use of a diet with tannins did not influence meat quality compared with a diet containing zinc bacitracin and salinomycin, which altered some parameters associated with meat colour. Moreover, the diet with tannins reduced (P &lt; 0.05) the number of oocysts of Eimeria sp. (36-day-old broilers) and the total faecal bacterial counts (42-day-old broilers) compared with the control group. Finally, intestinal histopathology showed that the addition of tannins minimised the degree of lesions (Degree 1) compared with the control group (Degree 3). On the basis of these results, we concluded that the use of quebracho extract containing tannins can be a suitable approach to improve the performance of broiler chickens, replacing in-feed antibiotics and coccidiostatic drugs. The use of tannins did not change meat quality; however, it caused positive effects on the immune system, and exerted potent bactericidal and coccidiostatic properties, reinforcing its use as a replacement for conventional drugs.

A feeding trial was conducted to investigate the effects of Piper sarmentosum leaves (PSL) on meat quality of broilers. The 144 commercial broiler chicks, one day old, were randomly assigned to 5 groups with three replicate cages. The five treatments were: 1) basal feed (8 chicks/cage), 2) basal feed (10 chicks/cage), 3) basal feed supplemented with 1% of PSL (10 chicks/cage), 4) basal feed supplemented with 2% of PSL (10 chicks/cage), and 5) basal feed supplemented with 3% of PSL (10 chicks/cage). The duration of dietary treatments was 42 days. The results showed that the group supplemented with 3% PSL had higher redness, yellowness, and cooking loss than the control group with 10 chickens/cage (P less than 0.05). It was also observed that the 3% PSL treatment gave significantly lower lightness than the 0% and 1% PSL treatments with 10 chickens/cage (P less than 0.05). Overall, the study indicated that PSL might improve chicken meat colour and protect against protein oxidation, but it has no potential in protecting against lipid oxidation in broiler filet.

Day-old male chicks were used to test the effects of a combination of formic and propionic acids (CFP) added to wheat- and barley-based diets on the performance and gut histomorphology of broilers. The CFP, containing formic and propionic acids based on an inorganic phyllo-silicate carrier, was added to starter and grower broiler diets of standard (NRC, 1994) or lower nutrient density (LND) using different levels of wheat and barley. Body weight gain (BWG) and feed conversion ratio (FCR) of broiler chicks were significantly (P < 0.001) improved by CFP supplementation at 21 days of age regardless of nutrient density (ND). However, at 35 days of age CFP addition significantly (P < 0.001) increased BWG and FCR. Proventriculus weight was also significantly affected by the dietary treatments. Ileal viscosity was significantly (P < 0.05) affected by ND which was associated with wheat and barley contents, whereas feed viscosity was significantly (P < 0.05) affected by CFP supplementation. Villus height was significantly (P < 0.05) increased by the CFP supplementation. In the case of villus width, an interaction effect was observed: there was a significant (P < 0.05) decrease in the group fed the standard ND diet, but only a numerical decrease in the group fed the LND diet compared to control group. No significant effect of dietary treatment on the thickness of the lamina muscularis mucosae could be detected.

A total of 225 day-old male broiler chicks (Ross-308) were randomly allocated to five treatment groups, with three replicates in a completely randomized design for 42 days. Birds were fed a basal-diet supplemented with: no additive (control-diet), multi-strain probiotic (Lactobacillus acidophilus, Lactobacillus casei, Enterococcus faecium and Bifidobacterium thermophilum), or 0.15, 0.20 and 0.25% ginger (Z. officinale) powder, respectively. The results show no significant differences among treatments for growth traits and carcass characteristics, whereas using probiotics and ginger at all levels resulted in a significant decrease of gizzard weight and abdominal fat compared to the control group. Dietary treatments did not affect blood biochemistry and antibody production against sheep red blood cells (SRBC), IgG and IgM; however, antibody titre was higher in birds fed 0.25% ginger than other diets after 7 days post injection. The Lactobacillus counts in ileal content of birds fed 0.20 and 0.25% ginger were higher compared to the other treatments. In conclusion, dietary supplementation with either ginger or probiotics showed a significant influence on birds’ immune response, probably because ginger had strong antioxidant activity and the probiotics stimulated the production of natural antibodies.
