Screening of oxytetracycline & chlortetracycline residues in poultry feeds in Bangladesh
Abstract
A total of 112 poultry feed samples were screened for oxytetracycline and chlortetracycline antibiotic residues by thin-layer chromatography (TLC). The samples were collected from Natore, Naogaon, Rangpur and Comilla districts of Bangladesh. Poultry feed samples were classified according to their product type (homemade, commercial) and types of poultry feed (broiler feed, layer feed and sonali feed). All the homemade poultry feed samples (100%) tested positive for oxytetracycline and chlortetracycline antibiotic residue when screened. About 95% of commercial poultry feed tested positive for antibiotic residue in all four districts. In this study, the positive screening for oxytetracycline and chlortetracycline antibiotic residue in broiler, layer and sonali poultry feed types are 98%, 95% and 90%, respectively. This study also observed that antibiotic residue remained in feed samples irrespective of temperature and time as they had been stored for about a year at room temperature. From this study, it was revealed that the use of antibiotics in poultry feeds was extensive. Moreover, the duration of sustaining in poultry feed also raised concerns regarding their use and effect on the environment. This study has also increased the concern about the strict monitoring of the use of antibiotics in the poultry industry.

Influence of humic acid on morpho-physiology and yield of rice
Abstract
A pot experiment was conducted to investigate the influence of soil organic amendments-cow dung and humic acid on morphology and yield of rice under drought stress at the net-house, Agricultural Botany Department at Sher-e-Bangla Agricultural University, during the period from July 2018 to November 2018. This single factorial experiment pots where arranged in a randomized complete block design with four replications. Four different levels of soil organic amendments viz. SM1 = Soil + inorganic fertilizer (control), SM2 = Soil + cow dung + inorganic fertilizer, SM3 = Soil + inorganic fertilizer + humic acid and SM4 = Soil + inorganic fertilizer + cow dung + humic acid. The results showed that morphological characters and yield of rice significantly increased with addition of cow dung and humic acid into the soil. In terms of morpho-physiology, the highest plant height 112.90 cm and number of tillers plant-1 11.25 were achieved from the treatment SM4 (Soil + inorganic fertilizer + cow dung + humic acid). In terms of the variables that contribute to the yield, the highest days to 1st flowering (72.75) and days to 1st maturity (122.05 days) were found from control treatment SM4 (Soil + inorganic fertilizer + humic acid + cow dung). Similarly, the highest panicle length (24.94 cm), number of filled grain panicle-1 (221.40), number of unfilled grain panicle-1 (42.25), root length (17.93 cm), number of grains panicle-1 (247.40), grain weight hill-1 (25.17 g), straw weight hill-1 (33.26 g) and harvest index (42.93%) were achieved from SM4 (Soil + inorganic fertilizer + cow dung + humic acid) . The highest soil moisture content (17.23 and 16.17% at 55 and 70 DAT, respectively) was also achieved from SM4 (Soil + inorganic fertilizer + cow dung + humic acid). This experimental results highlighted that together use of cow dung and humic acid increased the grain weight plants-1 more than 150% compared to controlled condition. Finally, it concluded that application of cow dung and humic acid as soil organic amendments increases the yield of aman rice.
