Relationship between the ratio of villous height:crypt depth and gut bacteria counts as well production parameters in broiler chickens
Tập 20 Số 3 - Trang 1-10 - 2021
The villous height to crypt depth (V:C) ratio is one of the most significant parameters which is associated with the nutrients’ absorption and greater body weight. The objective of this study was to assess the relationship between V:C ratio, gut bacteria counts and production parameters in broiler chickens. A total of 100 individual broilers were randomly selected from a farm with 40,000 Ross 308 ......

The use of water spinach (Ipomoea aquatica) in domestic wastewater treatment
Tập 17 Số 3 - Trang 49-54 - 2018
The main objective of this study was to examine the efficacy and capacity of using hydroponic systems in municipal pollutant removal at household scale. Three pilot scaled hydroponic systems [dimensionfor each system: 4.5 m (L) x Φ 114 mm] were installed to investigate the optimal age of vegetable, planting density and retention time for household wastewater treatment, respectively. Water spinach......

Field assessment of the efficacy of M.B., LIBDV and Winterfield 2512 strain vaccines against infectious bursal disease in chickens
Tập 17 Số 6 - Trang 15-23 - 2018
Live virus vaccines are very important parts of the prevention of Infectious Bursal Disease (IBD) in chickens. However, the successful IBD vaccination depends on IBD field pressure, vaccination technique, the immune status of the chicken, and especially IBDV strains used in the vaccines which are able to break through a higher level of maternal-derived antibodies (MDA). The objective of this field......
Spray-drying microencapsulation of β-carotene by polysaccharide from yeast cell walls
Tập 18 Số 6 - Trang 49-57 - 2019
It is well known that β-carotene plays an important role in human health. However, it is susceptibly degraded by environmental conditions including temperature, light and oxygen, due to its natural structure of conjugated double bonds chain. Polysaccharide (PS) from the yeast cell walls has appeared to be an excellent choice of encapsulating agent that can be used to encapsulate biologically activ......

Identification of porcine circovirus type 2 (PCV2), type 3 (PCV3) and porcine parvovirus (PPV) in swine by multiplex PCR test
Tập 20 Số 3 - Trang 11-17 - 2021
This study aimed to simultaneously detect three important viruses reported to be involved in the reproductive problems of sows. A multiplex PCR (mPCR) test was developed to provide rapid diagnosis of porcine circovirus type 2 and 3 (PCV2, PCV3) and to illustrate parvovirus (PPV) prevalence in sow herds. Three pairs of specific primers were designed to target PCV2 Cap gene, PCV3 Cap gene and PPV NS......

Genetic analysis of African swine fever virus based on major genes encoding p72, p54 and p30
Tập 20 Số 3 - Trang 18-25 - 2021
African swine fever (ASF) is reported as a highly contagious hemorrhage lethal disease of domestic and wild swine. The causative agent of ASF is a large enveloped DNA virus with a complex structure. There are twenty-four ASFV genotypes described to date. However, in Vietnam, only genotypes II had been previously described. The genetic characterization of ASFV enhances the understanding of ASF epid......
Prevalence, antimicrobial resistance profiles and virulence genes of Vibriospp. isolated from shrimp retails in Ho Chi Minh City (Vietnam)
Tập 18 Số 3 - Trang 27-34 - 2019
This study was conducted to determine the diversity of pathogenic Vibrio species, the antimicrobial resistance profile and the presence of virulence genes linked to food-borne pathogens of Vibrio spp. isolated from shrimp samples in Ho Chi Minh City, Vietnam. A total of 40 raw shrimp batches were collected from retails markets (supermarket and street). All 133 test strains were isolated from 40 sh......

Optimization of total phenolic extraction of Chromolaena odorata leaf for antifungal activity against plant pathogens
Tập 18 Số 6 - Trang 38-48 - 2019
Phenolic compounds are secondary metabolites mainly responsible for different pharmacological activities of the plant extracts. In this study, microwave-assisted extraction (MAE) variables were optimized for the extraction of the phenolic compounds from Chromolaena odorata (C. odorata) by using a central composite design (CCD) of response surface methodology (RSM). The optimized conditions were at......

Isolation and optimization of the growth conditions of thermophilic microorganism from hot springs
Tập 17 Số 3 - Trang 55-60 - 2018
The aim of this study was to isolate and optimize the growth conditions of thermophilic microorganism from hot springs. The isolation was conducted by using the mineral salt basal medium supplemented with 0.6% yeast extract at 500C. Totally, 33 isolates of thermophilic microorganism were isolated from hot springs at Truong Xuan (Khanh Hoa province) and Binh Chau (Ba Ria - Vung Tau province). The e......
Assessment of surface water quality and some main rivers’ capacity of receiving wastewater in Ca Mau province, Vietnam
Tập 21 Số 3 - Trang 53-66 - 2022
Surface water from rivers plays a significant role in socio-economic development in Ca Mau Province. It supplies freshwater for agriculture and aquaculture. Faced with the pressures of development, surface water quality in Ca Mau Province has been being at stake. The aim of this paper is to assess the water quality status and wastewater receiving capacity of the main rivers of Ca Mau Province. The......
