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.

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.

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.

Microbial resistance to antibiotics has become a problem plaguing the world. Currently, interest has been focused on exploring antimicrobial properties of plants and herbs. This work aim to evaluate the antibacterial activity of garlic (Allium sativum) bulbs and ginger (Zingiber officinale) rhizome on Brucella abortus isolates. Some concentrations of garlic and ginger extracts were tested for their antibacterial activity against B. abortus isolate brought from Central Veterinary Research Laboratory (CVRL), Soba, using well diffusion method. Moreover, minimum inhibitory concentration (MIC) and minimum lethal concentration (MLC) of garlic and ginger were tested using broth dilution method. Sensitivity pattern of the conventional antibacterial against common pathogenic bacteria was tested using disc diffusion method. Aqueous extract of ginger produced dose-dependent increase in the zone of inhibition at a concentration of 15% and higher, whereas the garlic extract produced inhibition zone at a concentration of 5% and higher, i.e. B. abortus isolate showed relatively high sensitivity toward garlic extract than ginger which required a more concentrated extract to kill or inhibit B. abortus isolate that brought from (CVRL), Soba, Khartoum, Sudan. Further studies are needed to find out the efficacy, safety, and kinetic data of their active ingredients.

To explore the feasibility of using fermented Chinese herbal mixture Zhihuasi Tk (Z. Tk) supplementation to increase the swine production, the protective effect of dietary supplementation with Z. Tk on the intestinal oxidative stress model and the regulation of both growth performance and intestinal microbiota of weaned piglets were investigated in vitro. Our results showed that the addition of Z. Tk increased the cell viability, prevented the decrease of glutathione peroxidase, and significantly increased the total antioxidant capacity and reduced the damage caused by H2O2 to the tight junction proteins of the porcine small intestinal epithelial cell line (IPEC-J2). Furthermore, weaned piglets supplemented with either 2 kg/ton zinc oxide (ZnO) or 4 kg/ton of Z. Tk in the diet increased body weight as well as average daily feed intake and daily gain, while the feed conversion rate and diarrhea rate decreased within 0–35 days. Results of the taxonomic structure of the intestinal microbiota showed that, in 21 days after weaning, the Firmicutes/Bacteroidetes ratio in experimental group was increased, while the abundance of beneficial bacteria such, as Lactobacillus, was increased by Z. Tk, showing inhibitory effect on pathogenic bacteria such as members of Proteobacteria. In summary, dietary supplementation with Z. Tk maintained the intestinal microbiota in a favorable state for the host to effectively reduce the abnormal changes in the intestinal microbial structure and improved growth performance of weaned piglets. Therefore, Z. Tk may potentially function as a substitute for ZnO in feed additives for weaned piglets in modern husbandry.

This experiment was conducted to evaluate the effect of various fat sources and their combination (coconut oil and soybean oil) on growth performance of broiler. A total of 80 one-day old female 1-d-old Arbor Acres were randomly assigned into four groups (4 treatment) with 10 replicates (6 birds per pen) within 42 days. The experimental groups consisted of four treatment of diets: 1) a basal-diet containing beef oil (BO),  2) a basal diet containing coconut oil (CO), 3) a basal diet containing soybean oil (SO), and 4) a basal diet containing coconut oil and soybean oil (CO+SO) as were used. Performance data were obtained during the feeding period. The result was shown that using combination of medium chain fatty acid and unsaturated fatty acid (CO+SO) were increased growth performance demonstrated by highest bodyweight (59.62 g) compared with other treatments (P 0.05) throughout the experimental period (0-42 days). The lower group for feed conversion ratio was obtained in the diet containing beef oil (BO) compared with other groups (1.32; P 0.05). Feed consumption and bodyweight have significantly different (P 0.05) but not different for feed conversion ratio (P 0.05). It can be concluded that feeding combination CO+SO in the diet may improve the performance of broiler.Beef oil; broiler; coconut oil; growth performance; soybean oil

A study was conducted at AFU livestock farm, Rampur, Chitwan in 2017-18 to determine the effect of dietary supplementation of garlic and ginger in different combination on feed intake, growth performance and economics by using commercial Cobb 500 broilers. A total of two hundred, 11-day-old chicks were allocated randomly to five different treatments. The experiment was designed in a Completely Randomized Design, each treatment with four replication and each replication had 10 birds. They were fed isoproteinous and isocaloric Basal diet (BD) and BD supplemented with four different levels of garlic and ginger such as T1 (BD only), T2 (BD + 1% garlic); T3 (BD + 1.0% ginger); T4 (BD + 0.5% garlic and 0.5% ginger) and T5 (BD + 1% garlic and 1% ginger). Weekly average body weight, weight gain, feed consumption, and feed efficiency were recorded up to sixth week of age. All data were statistical analyzed using Completely Randomized Design. The results showed that overall feed consumption was significantly (P≤0.05) higher for broiler fed diet supplemented with 0.5% garlic and 0.5% ginger (T4) followed by T5 (basal diet with 1% garlic and 1% ginger). On the other hand significantly higher (P≤0.01) cumulative weekly live body weight and body weight gain (g/bird) was found for the treatment with supplemented 1% garlic powder (T2), followed by broiler fed diet supplemented with 0.5% garlic and 0.5% ginger powder (T4). Similarly, feed conversion ratio was significantly (P≤0.01) better in broiler fed basal diet with supplementation of 1% garlic (T2) followed by basal diet with supplementation of 0.5% garlic and 0.5% ginger (T4). The maximum benefit was obtained from the broiler fed basal diet with supplementation of 1% garlic (T2). The findings revealed that broiler fed basal diet with supplementation of 1% garlic powder had helped as a growth promoter contributing to the better growth performance, feed efficiency and higher benefit: cost ratio. Thus, addition of 1% garlic powder can be safely recommended as a growth promoter in broilers.

Bacterial Meningitis (BM) is the most common serious infection of the central nervous system (brain and spinal cord). This research aims to determine the mineral composition and to evaluate the in vitro antibacterial activity of the Juice Extract of Allium Sativum, Ethanolic Extract of Allium Sativum and Aqueous Extract of Allium sativum (JEAS, EEAS and AEAS). The collected bulbs of A. sativum (600 g) were washed and air dried under shade for 2 hours and the dry scaly outer covering was peeled-off to obtain the fresh garlic cloves which were then divided into three parts of 200 g each. These three portions were crushed separately for cold extraction. The first portion was homogenized and poured into a muslin cloth to squeeze out the juice, while second and third portions were homogenized and submerged into 500 ml of 96% ethanol and 500 ml of distilled water respectively for 24 hours and both filtered after thorough shaking. The antibacterial activity of bulbs of A. sativum juice, ethanolic and aqueous (JEAS, EEAS and AEAS) extracts as folkloric medicine against clinical isolates were determined using Agar well diffusion and broth dilution method. Distilled water, concentrated nitric acid (HNO3) and hydrochloric acid (HCl) were used to digest the extract, which was then heated in water bath at 90ºC and filtered to obtain the filtrate for the analytical studies for A. sativum nutritional composition and zeolite herbominerals. The micro-herbominerals with their proximate values observed pharmacologic of Silver, Manganese, Zinc, Iron and Selenium; which has biocidal properties as well as immune system to cushioning the challenges of the BM pathogens. The minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and phytochemical screening of the extracts were evaluated. The results obtained showed that the juice and ethanolic extracts were potent, inhibiting the growth of clinical isolates with zone of inhibition ranging from 14-36 mm. The extracts inhibited bacterial isolates in concentration dependant manner with MICs ranging 0.02-15 mg/ml and MBCs 0.04-5 mg/ml. Phytochemical screening of the extracts revealed the presence of alkaloids, flavonoids, anthraquinone, carbohydrates, fats and oils, steroidal ring, saponins and terpenoids. This experimental investigation has provided the scientific validation basis for the ethnomedical use of A. sativum as a remedy to treat bacterial meningitis locally as anti-infectious agent.

Background and Objectives: Use of antibiotics as growth promoters in animal feeds has been restricted due to the residues in poultry products such as egg and meat, furthermore to the antibiotic resistant of pathogenic bacteria. The prohibition of their use opens the opportunity for the use of non-antibiotic feed additives such as probiotics. The objectives of this study were to investigate the effect of the addition of  Lactobacillus casei WB 315 and crude fish oil (CFO) to diets on growth performance, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), low density lipoproteins (LDL), high density lipoprotein (HDL), and cholesterol levesl of  broiler chickens. Materials and Methods: In this research, one-day old male broiler chicks were used and divided equally into four groups, namely a basal diet without L. casei WB 315 and without CFO (P0), basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and without CFO (P1), basal diet supplemented without L. casei WB 315 and 1% CFO of total broiler basal feed (P2), and basal diet supplemented with 0.5% L. casei WB 315 of total broiler basal feed (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed (P3) for 35 days. Results: The results of addition 0.5% Lactobacillus casei WB 315 (1.2 × 109 cfu/ml) and 1% CFO of total broiler basal feed after 35 days showed significant difference among treatment in feed efficiency (p<0.05), feed conversion ratio (p<0.05), feed consumption (p<0.05), EPA (p<0.05), DHA (p<0.05), increase HDL (p<0.05), reduced the LDL (p<0.05), and reduce cholesterol (p<0.05) in meat broiler chicken. Conclusion: It is concluded that the addition of L. casei WB 315 and crude fish oil (CFO) could significant improve the growth performance (feed efficiency, feed conversion ratio, feed consumption) and could significantly improve EPA, DHA and increase HDL and decrease LDL in meat poultry product.

Footpad dermatitis (FPD) is a major foot disease in modern poultry production, and it affects both poultry health and animal welfare. It refers to inflammation and necrotizing lesions on the plantar surface of the footpads and toes. We investigated the effects of providing a swimming pool and different floor types on growth performance and FPD score in indoor-reared White Roman geese. Forty-eight male and 48 female White Roman geese were randomly allocated to pens with or without a swimming pool and with either mud or perforated plastic floor and reared from 15 to 84 days of age. Growth performance measurements included feed intake (FI), weight gain (WG), and feed conversion ratio (FCR). FI, WG, and FCR were significantly decreased at various growth periods in geese provided with a pool. Lower WG and bodyweight for the perforated plastic floor group were found at 15–28 and 28 days of age, respectively. The geese reared on the perforated plastic floors without a pool had higher FPD scores at 70 and 84 days of age than those with other rearing conditions. A higher incidence of FPD score 1 was observed in geese raised without a pool. In conclusion, providing a pool can improve footpad health in indoor-reared White Roman geese but may not benefit growth performance.

The response of Clarias gariepinus to Allium sativum on growth performance and as anti-bacterial agent in Staphylococcus aureus challenge infection was evaluated. A. sativum was included at 0% (control), 1.5%, 3.0%, and 4.5% in fish diet. Twenty fish samples each were randomly distributed into four tanks (T1, T2, T3 and T4). Fish were fed twice daily at 5% body weight for twelve weeks. All fish were challenged with 0.5ml of pure culture of S. aureus. A significant (P<0.05) increase in body weight, total length and standard length was observed. A. sativum at 3.0% inclusion promoted highest growth with feed conversion ratio (1.25-1.41), protein efficiency ratio (1.72-0.56), specific growth rate (1.92-2.09), condition factor (0.83-1.99) and survival rate (60-95). Fish-fed A. sativum diet showed that 4.5% inclusion had the least S. aureus activity. Bacteria load significantly (P<0.05) decrease at week 12. Culture water had dissolved oxygen of 4.0 - 4.2 mg/L, pH 6.0 - 7.0 and temperature of 26.0-28.0oC. This study has shown that A. sativum supplemented diets enhanced growth of C. gariepinus and functioned as antibacterial agent against S. aureus. A. sativum at 3.0% inclusion in diet is recommended for better fish growth and 4.5% A. sativum for antibacterial action. Keywords: Fish, herb, growth, infection
