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.

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.

Consumer concern for drug residues in meat and eggs as well as ban imposed on the use of antibiotics in animal feed as growth promoter call for alternative search. A 56days feeding trial was conducted to investigate the effect of ginger inclusion with and without yeast supplementation on performance, carcass characteristics, gut micro flora of broiler chickens. A total of One hundred and eighty day, one old Arbor acre broiler chicks wereallotted on weight equalization basis to 6 dietary treatments in a 3 × 2 factorial arrangements (3 levels of ginger (0%, 4% and 5%) with and without yeast (0%, 1% levels). The treatments were replicated thrice with ten birds per replicate. Feed and water were provided ad- libtum. Performance showed that birds on combination (5% ginger and 1% yeast) recorded highest weight (1527g) with better feed conversion while least weight (1202g) and least feed conversion were recorded with birds on ginger only. Highest eviscerated weight (1362.50g) and dressing percentage (72.79%) were recorded in broiler chicks on 1%Yeast + 5% Ginger while least values (1087.50g, 62.39%) were recorded with birds on yeast only. Total bacteria count increased from 1.20 x106cfu/ml (control) to 1.70 x106cfu/ml in diets supplemented 1% yeast and 5% ginger as well as Lactobacillus count increased with supplementation level Total anaerobic count decreased from1.10 x106cfu/ml in control diet to 0.68 x106cfu/ml in birds fed1% yeast and 5% ginger likewise coliform, clostridium and bacillus counts decreased with the additives (yeast and ginger) inclusion. It can be concluded that inclusion of ginger and yeast at 5% and 1% respectively in the diets improved performance and reduced pathogenic biota without detrimental effects in broiler chickens and might therefore serve as a natural substitute for synthetic growth promoters.

A total of 300 day old broiler chicks (Hubbard) were assigned to 30 floor pens (10 birds per pen) under cyclic heat stress. Three diets including a control, as well as two levels of grape seed powder (GSP) and zinc (OZ) at the rates of 2.5 g/kg GSP + 50 mg/kg OZ and 5 g/kg GSP + 50 mg/kg OZ, were supplied to the broilers for 35 days. According to the results, broiler feed intake improved (p < 0.05) in GSP + OZ groups from 3–5 weeks and on an overall basis compared to the control diet. Body weight increased (p < 0.05) in GSP-5 + OZ-50 during weeks 2–5 and on an overall basis. The findings indicated that feed conversion ratio (FCR) decreased (p < 0.05) during week 5 in broilers supplemented with GSP-5 + OZ-50. The antibody titer (HI) against Newcastle disease (ND) was higher (p < 0.05) in GSP + OZ groups compared to control treatment. The value of malondialdehyde (MDA) decreased (p < 0.05) under GSP + OZ diets compared to control. Moreover, paraoxonase (PON1) was higher (p < 0.05) in GSP + OZ groups compared to untreated broilers. In conclusion, GSP + OZ positively supported growth traits, reduced MDA, and augmented PON1 and HI titer against ND in broilers exposed to heat stress.

Enzyme supplementation in diets based on corn and soybean meal can improve the productive performance of broilers. Thus, we aimed to evaluate the effect of the inclusion of different levels of an enzyme complex consisting of phytase, protease, xylanase, ?-glucanase, cellulase, amylase, and pectinase, for diets based on corn and soybean meal, on the parameters of 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 400), and six repetitions, with twenty animals each. The carcass yield and meat quality were evaluated at 35 and 42 days of age. We evaluated the characteristics of weight loss by cooking (WLC), shear force (SF), water holding capacity (WHC), pH, lightness (L*) and color (a* and b*). 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).

Hermetia Illucens

At present, there is limited knowledge about the possible utilization of the fat fraction derived from Hermetia illucens (HI) larvae processing. The objective of the present study was to evaluate the replacement of soybean oil with HI larvae fat in broiler finisher diet, on the quality and sensory traits of their meat. At 21 days of age, 120 male broiler chickens were randomly allocated to three experimental groups (5 replicates and 8 birds/pen): a basal control diet (C), and two groups in which either 50% or 100% of the soybean oil was replaced with HI larvae fat (the HI50 and HI100 group, respectively). At day 48, 15 birds (3 birds/pen) per group were slaughtered, and breasts and legs were excised and used for meat quality evaluations. Breast and leg physical meat quality, nutritional composition and sensory profile remained substantially unaffected by the dietary treatments. In contrast, the dietary incorporation of HI larvae fat modified the fatty acid (FA) profile of both the breast and leg meat cuts: the proportion of saturated fatty acids increased (p < 0.0001) to the detriment of the polyunsaturated (PUFA) fraction (p < 0.0001). Moreover, the meat n-6/n-3 ratio increased in the HI50 and HI100 groups compared to the C group. HI larvae fat dietary inclusion decreased the monounsaturated fatty acids in the breast (p = 0.0012) but not in the leg meat. Further research should focus on the improvement of the FA profile of the larvae through substrate modulation, or by combining HI larvae with a PUFA-rich feedstuff in feed formulations.

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.

The influence of feeding with starter diets containing spray-dried bovine colostrum (SBC), spray-dried bovine plasma (SBP), or spray-dried porcine plasma (SPP) on the growth performance and gut morphology of broiler chickens was investigated. The crude protein, lysine, and methionine plus cystine contents (g/kg as received) of SBC, SBP, and SPP were determined to be 766, 736, and 684; 58, 61, and 55; and 27, 28, and 24, respectively. The 3 test proteins were incorporated into a maize–soybean meal diet at a level of 50 g/kg and fed to 6 replicates of 8 male broiler chicks from 1 to 14 days of age. On Day 14, the experimental diets were replaced with a common grower-finisher diet, which was offered until Day 35. Dietary treatments had no effect (P > 0.05) on the weight gain or feed intake of birds during the first 14 days. However, feed/gain of birds fed the SBC diet was lower (P < 0.05) than of those fed the control diet. A trend for a reduction in feed/gain (P = 0.06) was observed in SBP and SPP diets. Dietary treatments had no effect (P > 0.05) on performance during Days 14–35 or Days 1–35. Villus height was increased by 5.7% (P < 0.05) and 4.6% (P = 0.05) in birds fed the SPP and SBP diets, respectively, compared with those fed the control diet. Crypt depth was 6% greater (P < 0.05) in birds fed the SPP diet and tended (P = 0.08) to be greater in birds fed the SBC diet, compared with birds fed the control. The ratio of villus height to crypt depth tended (P = 0.06) to be lower in birds offered the SBC diet compared with the control. Crypt goblet cell density was reduced (P < 0.05) by 13.9% in birds fed the SBC diet, compared with control birds. These results suggest that feeding with diets containing the SBC, SBP, and SPP during 1–14 days of age has some beneficial effects on broiler chickens. Further studies are needed to evaluate these products in less sanitary environments, which may increase the positive responses.

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.

Feeding trial experiment was carried out to evaluate the haematological and serum biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) as replacement of a conventional protein source. Proximate composition was done to determine the nutrient content of RSC and experimental diets. The experiment contained graded levels of RSC replacing soya bean cake (SBC). One hundred and twenty (120) day old Ross broiler chickens were used in a Completely Randomized Design (CRD). The broiler chicks were assigned to five dietary treatments with three replicates each with 8 birds per replicate and 24 birds per treatment. Five isonitrogenous and isocaloric diets were formulated for the broiler straight diet. Diet 1 served asthe control diet while diets 2, 3, 4 and 5 contained 8%, 16%, 24% and 32% RSC respectively. Data were collected and analyzed using analysis of variance and the mean was separated using Duncan multiple range test. The findings from the study showed that there were no significant (P?0.05) differences in all the parameters measured for haematology across dietary treatment means except for the white blood cell. The blood biochemical composition showed no significant (P?0.05) differences in total protein, high density lipoprotein, low density lipoprotein and creatinine across dietary treatments. RSC as an alternative feedstuff can replace soya bean cake at 24% in the diet of broiler chickens for improved haematological and blood biochemical of broilers. Roselle seed cake can replace SBC at the broiler chicken straight ration at 75% (24% dietary RSC) inclusion for better performance.
