 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Cassava Hay Supplementation on Antibacterial Activity of the Lactoperoxidase System in Raw Milk of Dairy Cows) ผู้เขียน: สุรีย์วรรณ พันธ์นรา, ดร.พรศรี ชัยรัตนายุทธ์, รองศาสตราจารย์ , ดร.ประวีร์ วิชชุลตา, รองศาสตราจารย์ , ดร.สมจิต สุรพัฒน์ , Uthai Kuntho, Wonganan Narongwanichakarn สื่อสิ่งพิมพ์:pdf AbstractSixteen multiparous cows in early-to-mid lactation (82.4?8.6 day in milk, DIM) were used in a completely randomized block design with repeated measurement to evaluate the effects of cassava hay (CH) supplementation on antibacterial activity of the lactoperoxidase system in raw milk. The cows were blocked into four groups based on DIM and previous milk yield. Each group was randomly fed dietary treatment twice daily for four months. Treatment diets were: T1) concentrate (control); T2) concentrate+1 kgCH/head/day; T3) concentrate+2 kgCH/head/day; and T4) concentrate+3 kgCH/head/ day. The concentrate for each treatment was formulated to provide together with CH, a daily intake of 1,830-1,940 gm protein. The cows received 25 kg/head/day of ruzi grass silage. After a 14-d adaptation period, daily milk yield was recorded and the raw milk of the cows was collected every month and analyzed for lactoperoxidase and thiocyanate concentration, standard plate, coliform, psychrotrophic and thermophilic counts. Milk yield and milk lactoperoxidase concentrations were not affected by treatments (P>0.05). Thiocyanate concentrations were higher (P<0.01) for T2, T3 and T4 than for T1. Standard plate, coliform, psychrotrophic and thermophilic counts were lower in T2, T3 and T4 compared to T1. The results showed that supplementation of cassava hay to dairy cows increased the efficiency of antibacterial activity of the lactoperoxidase system in raw milk. |

 ที่มา:วารสาร คณะสัตวแพทยศาสตร์หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Comparison of the Modified Reagent Test for Total Bacterial Count in Raw Milk with Methylene Blue Reduction Test) ผู้เขียน: Indhira Kramomtong, Thitima Tripipat, Chailai Koowatananukul, Suthep Ruangwises, Kittisak Ajariyakhajorn สื่อสิ่งพิมพ์:pdf AbstractThe study was conducted to develop the modified dye indicator by adding methyl red into methylene blue solution compared with the conventional methylene blue reduction test (MBRT) in terms of the correlation of total bacterial count (TBC), types of bacteria, pH and titratable acidity in raw milk. it was found that the regression line showed significantly close relationship between metylene blue - methyl red reduction test (MMRT) and MBRT. The decoloration time of MMRT was more related to TBC and coliform count than MBRT (R>0.5, p<0.05). Both dye reduction tests were related to pH at 4 and 6 hr. Additionally, the decoloration time of MMRT was correlated to titratable acidit at 4 hr compared to 6 hr with which from MBRT. In the other hand, the lactic acid content of 0.16 0.01 gm% at pH 6.52 0.01 affected dye decolorization from MMRT more obviously than the MBRT. Lactic acid production and pH changes were statistically highly related to coliform and total bacterial counts. Consequently,MMRT can be served as a new dye indicator and facilitate monitoring of milk quality. |
 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : A Study of the composition of Soil Extract Media for determining Total Bacterial Count of soil.) ผู้เขียน: Varaporn Kasemsanti, Santani Yooyen, Suchitra Xhauchuvej, Neeru Singhabootra สื่อสิ่งพิมพ์:pdf Abstract Total bacterisl counts were determined by dilution plate method with the use of soil extract media. The media were prepared form different quantities of soil extract obtained from upland, orchard and paddy soils.Highest total bacterial counts were observed in the media containing low, quantity of soil extract.The quantity of soil extract in the media that yieded highest total bacterial count was found to very with soil type. |
