The study evaluated the efficacy of ethanolic extracts of Catharanthus roseus (C. roseus) in altering growth performance, viscera  development and intestinal microarchitecture in broilers. Day-old broiler chicks (n = 175) were randomly divided into seven groups (n = 25/group) with 5 replicates (n = 5). The chicks in the control groups were fed a corn-soya-based basal diet, whereas groups 2 - 4 had the same basal diets supplemented with 0.05%, 0.1%, and 0.2% ethanolic leaf extracts (ELE), respectively. Chicks in groups 5 - 7 were fed the basal diet supplemented with 0.05%, 0.1%, and 0.2% ethanolic root extracts (ERE) of C. roseus, respectively. The growth performance and feed conversion ratio remained unchanged, but feed consumption of birds supplemented with 0.1% ERE increased in weeks 1 and 3. The relative length of the small intestine was lower in the 0.05% ERE group compared with the control. Villus height, width, surface area, and lamina propria thickness were higher in the 0.1% ERE group in all three segments of the small intestine than in the control. Broilers supplemented with 0.1% ERE performed better in terms of feed consumption and improved intestinal microarchitecture of the small intestine.

An experiment was conducted to investigate the effect of supplementing of exogenous phytase enzyme on productivity of commercial broilers. Four strains of commercial broiler such as Fast feather, Arbor acres, Cobb-500 and Hubbard classic each having 78 numbers were reared for a period of 5 weeks. A total number of 312 day old broiler chicks were distributed into two dietary treatments i.e. basal diet (Control-T0) and basal diet supplemented with phytase enzyme 1g/kg feed (supplemented-T1). The results indicated that broilers fed on diets supplemented with phytase have gained more body weight when compared with control group (P<0.05). The first and second highest body weights were recorded for the strains Cobb-500 and First feather broilers, respectively, which feed on diet containing phytase.   Feed consumption varied significantly between the broilers on different dietary regimes. Significant differences (P<0.01) were found in feed conversion ratios among the birds fed on diet with phytase enzyme. The lowest feed conversion ratio was in Cobb-500 fed on phytase diet where as the highest was in Fast Feather provided with only basal diet during the 5th week of age. Average feed conversion ratios were 1.73 and 1.86 for the supplemented and control group respectively. Use of phytase as feed additive in the diet resulted in high profitability/ broiler. Net profit per live broiler was the also higher in treatment group compared with control groups of birds. The highest net profit per live broiler was observed in Arbor Across strains fed on phytase diet. The result of the present study suggests that the addition of dietary phytase enzyme in the diet of broiler may increase the production performance and reduce the cost of production.Bang. J. Anim.

ABSTRACT-QMFS2019Poultry production provides source of protein and contributes an important income for Vietnamese farmers. Among the poultry in Vietnam, ducks account for 27.3% of head of poultry and even 55.7% in Mekong Delta region. Along with the development of rearing ducks, bacterial, viral and fungal diseases occurring in the two last decades induced bad effect for poultry producer. Escherichia coli, Salmonella enterica, Streptococcal or Pasteurella act as major pathogenic bacteria in duck. The aims of this study were to investigate the antibacterial activity of garlic Allium sativum against E. coli, Staphylococcus aureus, Salmonella Typhimurium and to evaluate the effect of garlic on growth performance of duck from 1-28 old-days. The results indicated that fresh garlic and dried garlic powder showed inhibitory effect against pathogenic tested strains from 2% and 4% w/v, respectively. The inhibition zones and the minimal inhibitory concentration (MIC) values of garlic extract ranged from 11.3-28.3 mm and 0.02-0.2 g/ml, respectively. After 28 days of diet with garlic supplemented, D3 (2% of fresh garlic in water) showed significantly different in weight gain (WG), feed conversion ratio (FCR), protein efficiency ratio (PER), average daily weight (ADW); whereas, D2 (2% of garlic powder in basal diet) only possessed a difference significant in feed consumption (FC) compared to the D1 (control without garlic supplementation). The obtained results demonstrated the potential of garlic application in poultry production.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloe and cinnamon powder on growth performance in commercial broilers .One hundred and twenty, day old Vencobb broiler chicks were procured and divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was incorporated with 1% giloe, 2% giloe, 1% cinnamon, 2% cinnamon and combination of 1% giloe and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P£0.05) higher in T3incorporated with 2% giloe. The feed conversion ratio was significantly (P£0.05) improved in broiler chicks fed diet incorporated with 1% giloe (T2). The performance index was significantly better in T2 and T3 compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T2 and T6 compared to other groups. Performance index was significantly higher in T2 incorporated with 1% giloe. During the whole experimental period (0-42 days), incorporation of 1 % giloe improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T1, T2, T3, T4, T5 and T6 were 1408.8, 1580.2, 1540.3, 1517.2, 1474.4 and 1551.0g, respectively. It can be concluded that giloe and/or cinnamon in combination can be fed to broilers to improve growth performance.

A synbiotic comprising Saccharomyces cerevisiae yeast (SCY) and Moringa oleifera leaf extract (MOLE) has been encapsulated using nanotechnology. This duo is used as a dietary supplement for growing rabbits. Physicochemical analyses, in vitro antimicrobial activity, and gastrointestinal system evaluation were used to evaluate the quality of the nanofabricated synbiotic. The in vivo study was conducted using 40-day-old male growing rabbits (n = 16 rabbits/group) to evaluate the effect of the nanofabricated synbiotic on the health and growth performance of examined rabbits. Rabbits were equally allocated into four groups; (a) NCS, which received a basal diet supplemented with a noncapsulated 11 × 1012 CFU SCY + 0.15 g MOLE/kg diet, (b) LCS: those receiving a nanoencapsulated 5.5 × 1012 CFU SCY + 0.075 g MOLE/kg diet, (c) HCS: those receiving an 11 × 1012 CFU SCY + 0.15 g MOLE/kg diet, and (d) CON: those receiving a basal diet without treatment (control). The treatments continued from day 40 to day 89 of age. During the experimental period, growth performance variables, including body weight (BW), feed consumption, BW gain, and feed conversion ratio were recorded weekly. Blood samples were collected on day 40 of age and immediately before the start of the treatments to confirm the homogeneity of rabbits among groups. On day 89 of age, blood samples, intestinal, and cecal samples were individually collected from eight randomly selected rabbits. The size and polydispersity index of the nanofabricated synbiotic were 51.38 nm and 0.177, respectively. Results revealed that the encapsulation process significantly improved yeast survival through the gastrointestinal tract, specifically in stomach acidic conditions, and significantly increased in vitro inhibitory activities against tested pathogens. Furthermore, treatments had no negative effects on hematobiochemical variables but significantly improved levels of blood plasma, total protein, and insulin-like growth factor-l. Compared to the CON, NCS, and LCS treatments, the HCS treatment increased the amount of intestinal and cecal yeast cells (p < 0.05) and Lactobacillus bacteria (p < 0.05) and decreased number of Salmonella (p < 0.05) and Coliform (p = 0.08) bacteria. Likewise, both LCS and HCS significantly improved the small intestine and cecum lengths compared to CON and NCS. The HCS treatment also significantly improved BW gain and feed conversion compared to CON treatment, whereas the NCS and LCS treatments showed intermediate values. Conclusively, the nanoencapsulation process improved the biological efficiency of the innovative synbiotic used in this study. A high dose of encapsulated synbiotic balanced the gut microflora, resulting in the growth of rabbits during the fattening period.

This study was carried to evaluate the “Effect of Garlic (Allium sativum) oil inclusion on carcass quality, growth performance and cost implication of broiler chickens”. A total of 180 day–old-(Arboacre) broiler chicks purchased from a reputable hatchery was used in the study which lasted for eight (8) weeks. The birds were divided into four experimental groups; each group was further subdivided into three replicates of fifteen birds per each in a Complete Randomized Design (CRD). The birds were fed on two basal diets (Starter and finisher) in an experiment which lasted for eight weeks. The garlic oil (Allum sativum) was added to the basal diet at (0.00, 0.1, 0.2, 0.3%) level respectively. The treatment were T1, T2, T3, and T4 with T1 serving as control. Growth performance, carcass characteristics, and cost implication were recorded. At the end of the experiment, the birds were slaughtered, dressed to estimate the different parameters. The result showed that the diet with 0.3% garlic oil inclusion had significantly (P<0.5) highest body weight and highest dressing percentage. Control treatment (0.0%) had highest feed intake and best feed conversion ratio. The mortality rate was not affected significantly by the addition of garlic oil in broiler diet. The garlic oil inclusion reduced the mortality rate of the birds, increases productivity and food safety. The result showed on cost implication reveal the economical evaluation of the experiment diets indicated that, the diet with 0.3% level of garlic oil showed the highest profitability ratio as compared to the group. This might be due to the highest return of the weight gains recorded by this group of chicken.

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 aim of this study was to evaluate the effects of sodium butyrate (SB) on growth performance and development of digestive and immune organs in broilers. Dietary treatments had similar compositions but with 0%, 0.03%, 0.06%, and 0.12% SB substituted (weight/weight) for identical amounts of the basal diet. SB supplementation linearly increased (P &lt; 0.05) average daily gain for each period, except for days 15–21. SB supplementation linearly increased (P &lt; 0.05) the relative weight of proventriculus (day 7), gizzard (days 7 and 14), duodenum (days 21 and 28), jejunum (day 21), ileum (day 21), small intestine (day 21), rectum (day 14), pancreas (days 7 and 21), liver (days 21 and 28), and thymus (days 7, 14, and 21). SB supplementation linearly increased (P &lt; 0.05) the relative length of duodenum (day 21), jejunum (days 14 and 21), ileum (days 14 and 21) and small intestine (days 14 and 21), caeca (day 21) and rectum (day 21), as well as it improved intestinal structure by increasing the villus height in jejunum and ileum, and increasing goblet cell counts in duodenum, jejunum, and ileum. Collectively, dietary SB supplementation improved the growth performance of broilers by improving the development and morphological structure of the broilers’ intestinal organs.

Abstract This study aims to investigate the effects of commercial probiotic supplementation in water on the performance parameters, carcass traits, immune function, and antioxidant capacity of broiler chicks. In the experiment, 120 Arbor Acres (AA) broilers (60 male and 60 female) were randomly allocated into four groups (G) – G1: basal diet and G2, G3, and G4: basal diet with 1% Lactobacillus casei, 1% L. acidophilus, and 1% Bifidobacterium in the water, lasting 42 days. The experimental results revealed that probiotic additives produced positive impacts on body weight, average daily feed intake (ADFI), and average daily weight gain for female chicks, whereas these probiotics significantly reduced ADFI and the feed conversion ratio of male chicks (P < 0.05). Probiotics efficiently improved eviscerated yield and breast yield while reducing the abdominal fat (P < 0.05) for the male broiler chicks. A marked increase was observed in the weight of the spleen, bursa of Fabricius, and thymus in the treatment group (P < 0.05). Besides, probiotics produced a significant effect on the concentrations of immune-related proteins (P < 0.05) and markedly increased the concentrations of antioxidase and digestive enzymes when compared with the control (P < 0.05). The addition of probiotics dramatically reduced the total counts of Escherichia coli and Salmonella and increased the quantity of Lactobacilli (P < 0.05). The results of the present study demonstrated an increase in growth performance, carcass traits, immune function, gut microbial population, and antioxidant capacity by supplementing 1% probiotics (L. casei, L. acidophilus, and Bifidobacterium) in the water for broilers.

This study aimed to explore the effects of Marjoram (Origanum majorana L.), on growth performance, carcass characteristics, and immunity in broilers. A sixty of one-day-old Cobb broiler chicks were randomly divided into 2 groups; Chicks of group 1 were fed on basal diet considered as a control group, chicks of group 2 were fed on an experimental ration containing 2% marjoram. The results showed that the Marjoram significantly increase (P<0.05) some growth factors as bodyweight after 3rd, 4th and 5th weeks, weight gain at 3th and 5th weeks, also significantly improved feed conversion ratio (FCR) at 3rd, 5th weeks in comparison with the control group. Also, Marjoram supplementation at the level of 2% caused a significant elevation (P˂0.05) in gamma globulin, thus marjoram could be considered as an immunity enhancer for broilers. In conclusion, the present study proved that supplementation of the ration with Marjoram could improve growth performance and immunological state in broilers.
