Assessment of Phosphorus Levels in Small Ruminants as Affected by Summer and Winter

Journal of Northeast Agricultural University(English Edition) 2014年第1期21卷 45-51页

作者： ansar Mahmood Dr.Asma Hassan Iram Maqsood Tang Li-jie syed Mohsin Bukhari Khalil-Ur-Rehman and Shahla Andleeb Department of Wildlife and Fisheries Government College University College of Veterinary Medicine Northeast Agricultural University

An experiment was carried out to assess the phosphorus status of free grazing goats at Faisalabad, Pakistan. Samples were collected fortnightly during summer and winter seasons of 2010 from soil and plants. The highest （1183±0.54 mg. kg1） levels of feces phosphorus were recorded in lactating goats during winter and （9.87±0.99 mg＂ kg1） in urine of male during winter. Similarly maximum （71.0±0.88 mg ＂kgt） phosphorus concentration was observed in the plasma of lactating animals. Milk contained （31.0±0.36） rag. L^-1 in winter while during the months of summer the highest values recorded in forages, soils, canal and tube well waters were （755±1.98） mg. kg^-1, （785±4.98） mg· kg^-1, （0.97±8.78） mg·L^-1 and （4.12±0.55） mg. L^-1, respectively. It was revealed from the current results that fecal matter, forage, milk, tube well and canal water contained lower amounts of P, while P levels in blood plasma was found within the critical limits. Therefore, phosphorus supplementations were required in the area under experimentation to meet the requirements of the animals for their normal growth.

We experimentally designed dispersion-managed repeaterless transmission systems with a pre-compensation and post-compensation technique using multi-channel-chirped fiber Bragg gratings. The repeaterless transmission link supports a single channel（1548.51 nm） with a 10 Gbps repeaterless transmission system over 300 km standard single-mode fiber（SSMF）. In the system design, two distributed Raman amplifiers（DRAs） were used to improve the signal level propagated along the 300 km SSMF. The co-propagating DRA provided 15 dB on–off gain and the counter-propagating produced 32 dB on–off gain at the signal wavelength. The experiment results show that the post-compensation configuration achieves an optimal performance with a bit error rate at 1 × 10-9.
