Tyrosine Ameliorates Some of the Clinical,Biochemical and Haematological Effects of Acute Stress Associated with Transportation of Desert Sheep     

Ali BH  Al-Qarawi AA  Mousa HM  Mohammed SM 《Veterinary research communications》2001,25(6):503-510

We studied some clinical, biochemical and haematological variables in Desert (Najdi) sheep acutely stressed in the course of individual road transportation, and the influence thereon of pretreatment with tyrosine. Transportation for 30 min resulted in variable but statistically insignificant increases in heart, pulse and respiratory rates. It also caused significant increases in the plasma concentration of cortisol (from 43.5 to 101.7 mmol/L) and glucose (from 3.1 to 4.5 mmol/L), and a decrease in that of magnesium (from 0.85 to 0.72 mmol/L). The endogenous thiocyanate level was unaffected. The transportation stress also decreased the haematocrit (PCV) and the number of lymphocytes, and increased the concentration of haemoglobin. Pretreatment of sheep with tyrosine at a dose of 100 mg/kg by the intravenous route significantly ameliorated the stress-induced clinical, biochemical and haematological changes. The treatment caused no overt adverse effects.  相似文献

Analysis of nestling food in four species of Parus and one species of Ficedula using the 'Halsringmethode' showed a high quota of adults and caterpillars of the important forest pests: Tortrix viridana, Euproctis chrysorrhoea, Diprion pini, and Lymantria dispar. These four major pest species amounted in the nestling food of Parus major to 50%, P. coeruleus to 52.6%, P. ater to 40.9%, and Ficedula hypoleuca to 30.2%.  相似文献   

The fluorescent antibody and indirect fluorescent antibody assays for diagnosing stunting syndrome of turkeys     

Reynolds DL  Oesper J  Ali A 《Avian diseases》2000,44(2):313-317

The fluorescent antibody (FA) assay was developed for detecting the stunting syndrome agent (SSA) from intestinal tissue. Similarly, the indirect fluorescent antibody (IFA) assay was developed for detecting serum antibodies to SSA. Convalescent antiserum from turkeys orally immunized with SSA was found to be the primary antibody of choice for the FA assay. Intestinal jejunal samples from poults inoculated 3-4 days postinoculation (DPI) was found to be the best antigen source for the IFA assay. SSA was detected from the intestinal tracts of experimentally inoculated birds at 2 DPI with highest level of reactivity at 3 DPI by the FA assay. After 4 DPI the level of SSA infectivity of the intestines waned to low levels. Serum antibody was detected from experimentally inoculated birds as early as 7 DPI with all birds tested seroconverting by 12 DPI. These assays should prove useful for future studies concerning stunting syndrome.  相似文献   

Effect of root applied 28-homobrassinolide on the performance of Lycopersicon esculentum     

B. Ali  S. HayatS. Aiman Hasan  A. Ahmad 《Scientia Horticulturae》2006

The roots of 20 days old seedlings of tomato (Lycopersicon esculentum Mill.) at the time of their transplantation, were dipped in 10⁻⁸, 10⁻⁷, 10⁻⁶ or 10⁻⁵ M of 28-homobrassinolide (HBR) for 15, 30 or 45 min and were allowed to grow in earthen pots, in a net house. The leaves of the plants, at days 30 and 60, possessed elevated quantities of nitrate reductase (NR), carbonic anhydrase (CA) and the contents of chlorophyll. The values for all the above characteristics were significantly higher than that of the water-fed control. The fruits borned at the treated plants were more in number and possessed a lower quantity of ascorbic acid than the control. Moreover, the fruits at ripening, had higher levels of lycopene and β-carotene. Among the treatments, 15 min feeding of 10⁻⁸ M HBR proved best.  相似文献

辣椒（Capsicum spp．）原产于中南美洲，大约450～500年前，由葡萄牙商人引入印度，并很快在印度大量栽培，成为印度的重要经济作物。2003年印度辣椒种植面积94．55万hm^2，年产鲜椒450万t。印度是辣椒生产大国，也是世界上种植pimento红辣椒最大的国家，面积和产量分别占全球市场份额的46％和44％，单产4．7t／hm^2，低于中围（25．6/hm^2）、  相似文献   

Effects of Stocking Density and Monosex Culture of Freshwater Prawn Macrobrachium rosenbergii on Growth and Production in Concrete Tanks in Saudi Arabia     

Abdul Qayyum  Siddiqui  Yousef S.  Al-Hafedh  Ahmed H.  Al-Harbi Seikh A.  Ali 《Journal of the World Aquaculture Society》1997,28(1):106-112

Abstract This study was conducted to evaluate the effects of stocking density and monosex culture on growth, survival, yield and feed conversion ratio of freshwater prawn Macrobrachium rosenbergii in concrete tanks. Juvenile prawns with an average weight of 1.8 g were stocked into triplicate tanks at densities of 5, 10, 15 and 20 prawns/m², grown for 168 d and fed a 34% tilapia diet. Stocking density had significant effect on prawns. Final mean body weight decreased with the increasing density, being highest at 5 prawns/m² (29.6 9). and lowest at 20 prawns/m² (17.4 g). Total yield increased from 135 g/m² (1,350 kg/ha) at a density of 5 prawns/m² to 261 g/m² (2,610 kg/ha) at density 15/m^z to 245 g/m² (2,450 kg/ha) at 20/m^z. Feed conversion ratios were high and ranged from 3.7 (5 prawns/m²) to 5.6 (20 prawns/m²).
In monosex culture of freshwater prawns stocked in triplicate tanks at a density of 5 prawns/m² for 112 d, the all-male population had the best growth performance and feed conversion ratio, followed by the mixed-sex and all-female populations. The all-male population had 99% marketable prawns (>20 g) with an average yield of 159 g/m² (1,590 kg/ha); the mixed-sex population had 90% marketable prawns and the yield was 135 g/m^z (1,350 kg/ha); and the all-female population had 75% marketable prawns with an average yield of 108 g/m² (1,080 kgha).  相似文献

Early heat acclimation during incubation improves Japanese quail performance under summer conditions

Effects of exposing quail eggs to high temperature on the heat tolerance ability and productivity of birds were investigated. Four groups of 600 fertile eggs were randomly selected; the first group was incubated under 37.5 °C and the hatched chicks were reared under a gradual decrease in temperature from 35 to 24 °C (Control). The second group was exposed to 39.1 °C for 2 h/day during 4–14 days of embryogenesis and the hatched chicks were reared under a gradual decrease in temperature from 35 to 24 °C. The third group was incubated under 37.5 °C and the hatched chicks were exposed to 39?±?1 °C for 2 h/day during 4–14 days of age. The fourth group was exposed to 39?±?1 °C for 2 h during 4–14 days of embryogenesis and the hatched chicks were exposed to 39?±?1 °C for 2 h/day during 4–14 days of age. The temperature applied changed (P?<?0.01) embryo weight and incubation period. Birds exposed to high temperature during brooding had superior growth performance, dressed carcass, body temperature and health traits. Birds subjected to 39?±?1 °C during brooding exhibited decreased feed consumption and body weight gain. Finally, this work suggests that thermal acclimation during embryogenesis might offer a practical method for easing heat stress.
