肾复康对高蛋白饲料诱发鸡尿酸盐沉着症的预防效果

给28～49日龄期间的罗曼蛋用公雏连续饲喂高蛋白饲料(蛋白质含量为40 %)。同时按1.0‰和0.5‰给鸡连续饮水投服肾复康 ,并测定检查了健康对照鸡、人工发病未用药鸡和肾复康预防鸡的血清尿酸含量、生长增重。人工发病未用药鸡于饲喂高蛋白饲料7d后陆续出现发病 ,临床症状和解剖病变较为典型 ,到试验结束死亡16.7 %(5/30) ,肾复康预防鸡与人工发病未用药鸡相比血清尿酸含量显著降低(P<0.05) ,生长增重极显著增多(P<0.01)。由此说明 ,肾复康对高蛋白饲料诱发的鸡尿酸盐沉着症具有显著的预防作用 ,而且能明显促进鸡的生长增重

Studies on Nitrogen Economy and Productivity of Wheat as Affected by Rainy Season Legumes under Irrigated Conditions

A field experiment was conducted during July 1986–April 1988 at New Delhi, to evaluate the relative contribution of rainy-season legumes towards the growth and productivity of succeeding wheat ( Triticum aestivum [L.] emend. Fiori & Paol), find out economic optimum dose of nitrogen for succeeding wheat and screen a legume which can be best knitted in wheat based cropping system.
HD 2329 wheat performed better when grown after legumes than when grown after Local fodder sorghum ( Sorghum bicolor [L.] Moench). N economy in wheat was greater (65–78 kg/ha) after Sona clusterbean ( Cyamopsis tetragonoloba [L.] Taubert) and T-9 blackgram ( Phaseolus mungo L.) over sorghum. The economic optimum dose of N for wheat following pigeonpea ( Cajanus cajan [L.] Millsp.), soybean (Glycine max [L.] Merr.), groundnut ( Aracbis bypogaea L.), blackgram ( Phaseolus mungo L.) and clusterbean were 110.1, 103.6, 113.7, 109.6 and 92.3 kg/ha respectively.

整秸秆氨化饲料的技术效果与区域适应性研究

充分利用中国丰富的秸秆资源发展节粮型草食畜牧业是中国畜牧业发展的重要方向。针对目前秸秆氨化技术存在的问题,开展了10多年的整秸秆氨化饲料技术创新研究,研究结果表明,整秸秆氨化饲料比传统地窖氨化饲料,蛋白质含量提高了1.33~1.46倍;饲料呈黄褐色,伴有爆米花香带酸甜味的酥脆感;牛羊采食量提高15%,消化率提高45%;每头牛每年节约饲料费500元、纯收入1200元左右。这一技术在山西省和海南省的不同地区进行了试验示范,不同作物的蛋白质含量基本稳定在10.5~11.06 g/kg。其广泛适应于中国不同类型区,对充分利用秸秆资源、促进中国规模化草食畜牧业发展具有重要作用。     

Forest utilization patterns and socio-economic status of the Van Gujjar tribe in sub-Himalayan tracts of Uttarakhand, India

The present study was conducted on the Van Gujjar tribe inhabiting a sub-Himalayan tract in the North Western Himalayas of Uttarakhand State,India.The Van Gujjars have been practicing transmigration over hundreds of years.They migrate each year with their households and livestock between summer and winter pastures.A few years ago with the announcement of the establishment of the Rajaji National Park,the tribe has been forced out of the forest area and rehabilitated outside the park,which has affected their lifestyle.The newly established rehabilitation colony in the Gandikhata area of Haridwar District of Uttarakhand State was taken as a case study.The aims of the present study were to understand and evaluate the socio-economic status of the Van Gujjars in their newly established rehabilitation colony,the utilization pattern of forest resources by the tribe and their relative preference for selective trees for various uses.A total of 176 households were interviewed (giving equal weight to all economic classes and family every size) by using pre-structured questionnaires.The education level was very low (12.9%) and the average income per household was recorded as Rs.36000 (approximately $ 803) per year.The major source of income was dairy production (80.6%) followed by labor employment (13.9%),NTFPs (4.2%) and agricultural production (1.4%).More than 90% of fuel wood and fodder is extracted from the forest.The average fuel wood and fodder consumptions per household per day were recorded as 25.86 and 21.58 kg,respectively.A total of 35 species of cultivated plants and 89 species of wild plants were found to be utilized as food sources.Selectively 25 wild tree species are well known as being used by the Van Gujjars as fodder,fuel wood,agricultural implements,household articles,dye,medicine,fiber and other products.According to their utility value,the most preferred and useful tree species is Ougeinia oojeinensis,followed by Terminalia alata,Bombax ceiba,Shorea robusta and Dalbergia sissoo.

Pigeonpea Nutrition and Its Improvement

Abstract

Pigeonpea (Cajanus cajan [L.] Millsp.), known by several vernacular and trade names such as red gram, tuar, Angola pea, Congo pea, yellow dhal and oil dhal, is one of the major grain legume crops of the tropics and sub-tropics. It is a favorite crop of small holder dryland farmers because it can grow well under subsistence level of agriculture and provides nutritive food, fodder, and fuel wood. It also improves soil by fixing atmospheric nitrogen. India by far is the largest pigeonpea producer where it is consumed as decorticated split peas, popularly called as ‘dhal’ In other countries, its consumption as whole dry seed and green vegetable is popular. Its foliage is used as fodder and milling by-products form an excellent feed for domestic animals. Pigeonpea seeds contain about 20-22% protein and appreciable amounts of essential amino acids and minerals. Dehulling and boiling treatments of seeds get rid of the most antinutritional factors such as tannins and enzyme inhibitors. Seed storage causes considerable losses in the quality of this legume. The seed protein of pigeonpea has been successfully enhanced by breeding from 20-22% to 28-30%. Such lines also agronomically performed well and have acceptable seed size and color. The high-protein lines were found nutritionally superior to the cultivars because they would provide more quantities of utilizable protein and sulfur-containing amino acids.
