This study was conducted to assess the impact of growing condition variables on alfalfa ( L.) productivity. A total of 197 alfalfa yield results were acquired from the alfalfa field trials conducted by the South Korean National Agricultural Cooperative Federation or Rural Development Administration between 1983 and 2008.

The objective of this study was to evaluate the nutritive value of polished rice (PR) vs unpolished rice (UPR) as a potential feedstuff for sheep in order to use as a replacer to corn in sheep diet, and as well as to present the application in the formulation of cattle diet. Six corriedale ewe were randomly assigned to each treatment. UPR and PR were provided as a dietary treatment together with timothy grass as a basal diet in a crossover design for two period with 15-d duration for each period.

Article Synopsis
  • The study focused on creating a method to extract cortisol from sturgeon fins using two solvents, water and isopropanol, and comparing cortisol levels across three sturgeon species: beluga, Siberian, and sevruga.
  • Cortisol extraction involved a series of precise steps, including washing samples, air-drying, grinding, and using methanol for extraction followed by analysis with ELISA.
  • The findings revealed no significant differences in cortisol levels among the sturgeon species or between fin and jawbone samples, suggesting that jawbone may be a useful stress indicator in sturgeons.

Background: Two experiments were implemented using three cannulated crossbreed rams (Corriedale × Suffolk) fed rice straw-based diet. In vivo evaluation of garlic powder (GP) supplementation to rice straw-based diet on CH and CO emissions and blood profiles of the rams (body weight = 52 ± 3 kg) was performed. The design was a triplicate 3 × 3 Latin square.

The objective of this study was to determine the effects of chromium methionine (Cr-Met) chelate supplementation on blood metabolites and fatty acid profile of beef from Holstein steers during late fattening period. Fifteen Holstein steers were allotted randomly into two groups including the control (non Cr-Met feeding, NCM, ave. body weight [BW] = 483±25.

Fish waste (FW) obtained from a fish processor was ensiled for biogas production. The FW silages were prepared by mixing FW with bread waste (BW) and brewery grain waste (BGW), and the quality of the prepared silages were evaluated. The biogas potentials of BW, BGW, three different types of FW, and FW silages were measured.

The objective of this study was to investigate the feasibility of anaerobic co-digestion of Kimchi factory waste silage (KFWS) with swine manure (SM). Chinese cabbage (CC) is the major waste generated by a Kimchi factory and KFWS was prepared by mixing CC and rice bran (RB) (70:30 on a dry matter basis). In Experiment I, the biogas potential of CC and RB were measured and, in Experiment II, the test was conducted with different ratios of KFWS and SM (KFWS: SM=0:100; 33:67; 67:33; 100:0 by% volatile solids (VS) basis).
