Although the number of dairy farms is decreasing, that of large farms is increasing in Japan. Milk production in Japanese dairy cows has increased from 62 kg/year to 88 kg/year over the last 2 decades. However, Japanese dairy cows are experiencing a sustained decline in reproductive performance, calving intervals, and days open; further, the number of inseminations required for conception have ...

two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of ecg and subsequent hcg treatment on the reproductive performance of estrus-induced mature lori ewes. in the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (fga) sponges or controlled internal d...

the present study seeks to investigate users’ perception and evaluation of the function of designed environments and highlights a deeper understanding of man-environment relationship. the study tries to answer the question: “is there any relationship between the physical features of environment and users’ perception and evaluation of the environment and their spatial behaviors?” such investigat...

The present study aimed to investigate the combined effects of Taxol and cyclooxygenase (COX) inhibitors on angiogenesis and cell apoptosis of SKOV-3 human ovarian carcinoma cell xenograft-bearing mice. The experiments were continued for 28 days. Animals were treated with 3 mg/kg SC-560 (a COX-1-selective inhibitor) alone, 100 mg/kg celecoxib (a COX-2-selective inhibitor) alone or SC-560/celeco...

residual stresses resulting from rapid quenching of molten metal in melt spinning process can be removed by structural relaxation of samples at temperatures lower than the crystallization temperature in order to improve the magnetic properties. in this research, amorphous fe78si9b13 ribbons (metglas 2605s2 used in transformer cores) with the thickness of 26 µm were prepared by chill block melt ...

Three strains of Gram-negative bacteria capable of removing geosmin from drinking water were isolated from biologically active carbon and identified to be Chryseobacterium sp., Sinorhizobium sp. and Stenotrophomonas sp. based on physio-biochemistry analysis and 16S rRNA gene sequence analysis. Removal efficiencies of 2 mg/L geosmin in mineral salts medium were 84.0%, 80.2% and 74.4% for Chryseo...

Submicron-sized airborne particulate matter (PM) is not collected well on regular quartz or glass fiber filter papers. We used a micro-orifice uniform deposit impactor (MOUDI) to fractionate PM into 6 size fractions and deposit it on specially designed high-purity thin aluminum disks. The MOUDI separated PM into fractions 56–100, 100–180, 180–320, 320–560, 560–1000, and 1000–1800 nm. Since the ...

The primary aim of this study was to evaluate the performance sorted semen in dairy cattle various breeds Uttarakhand. Total 6382 inseminations were performed different districts. Different factors considered for region, dam breed, parity number, insemination season, bull breed used insemination. Sorted provided by Uttarakhand Livestock Board. and statistical analysis using R version 4.3.1 soft...
