The effects of equithesin administered IV “to effect” were evaluated in twelve adult domesticated camels (Camelus Dromedarius). The mean dose required for “to effect” anaesthesia as 0.74 ± 0.03 ml/kg. Moderate relaxation of muscles lasted 30 to 45 minutes and duration of analgesia was 10–15 minutes. The sleeping time was 15 to 45 minutes and the animals showed recovery in 75–115 minutes. During anaesthesia, there was moderate tachycardia, transient hypotension and decrease in central venous pressure. Primary T wave changes were a consistent finding in the ECG. There was mild hypoxemia, mild hypercapnia and significant decrease in arterial-venous oxygen tension difference. A significant decrease in the total leucocyte count occurred during the peak effect of anaesthesia. Hyperglycaemia observed at the peak anaesthetic effect was followed by hypoglycaemia 24 hours after administration of equithesin. The changes in rectal temperature, respiratory rate and other biochemical constituents studies were not significantly affected. 相似文献

1. De‐oiled mango seed kernel meal (MSK) was found to contain tannins, cyanogenetic glucosides and traces of alkaloids and gums. Treating with 0#lb3 m HCl followed by Ca(OH)2 suspension removed all of the tannins and much of the cyanogenetic glucosides and gums.
2. Substitution of 141 g MSK/kg diet for maize in a practical diet did not affect performance of chicks, whereas adverse effects occurred with 282 g or more/kg.
3. Processing of MSK improved performance but it was still not equivalent to that achieved with maize.
4. Increasing the protein content of the diet containing processed MSK from 207 to 226 g/kg did not improve performance and replacing ground nut meal with soyabean meal depressed performance. 相似文献

Administration of α-naphthylthiourea to albino rats caused excessive urinary excretions of albumin, inorganic phosphorus, and urea in 22 hr. Levels of inorganic phosphorus, glucose, and creatinine were elevated in blood and in the pleural effusion. Urea contents in blood and pleural effusion were progressively increased with concomitant rise in arginase activities. Significant increases were observed in phospholipids, triglycerides, and cholesterol concentrations in blood. No changes were noticed in cholesterol and fat contents of the liver. Kidney sections showed lesions in the glomerular region after 8 hr, and in the later stages, the histopathological evidence was suggestive of acute glomerular nephritis of the lipoidal type. 相似文献

Protein fibre wastes from animal hairs, feathers and insect secreted filaments can be aptly utilized by converting them into ultra-fine particles. Particles from animal protein fibres present large surface-to-weight ratio and significantly enhanced surface reactivity, that have opened up novel applications in both textile and non-textile fields. This review article summarizes the state-of-the-art routes to fabricate ultrafine particles from animal protein fibres, including direct route of mechanical milling of fibres and indirect route from fibre proteins. Ongoing research trends in novel applications of protein fibre particles in various fields, such as biomedical science, environmental protection and composite structures are presented. 相似文献

Selection for genetically superior Murrah buffaloes under Network Project on Buffalo Improvement, India, is presently based on milk yield, and it was observed that even in the absence of any direct selection pressure applied on fertility, there has been a downward trend in fertility associated with the selection for milk yield. The aim of the study was to develop selection indices which include fertility besides milk yield in Murrah buffaloes. Data pertaining to 1,224 lactation records spread over a period of 19 years were recorded and analyzed in the study. The negative association of pregnancy rate (fertility) with a 305-day milk yield (?0.08?±?0.04) and wet average (?0.12?±?0.02) indicated the importance of incorporating fertility trait in the construction of selection index. Four types of selection indices were constructed and evaluated. Two indices were developed using expected producing ability 305-days milk yield (EPAMY) with 6.5 and 4 % fat in milk along with expected fertilizing ability (EFA). The other two indices developed consist of expected producing ability wet average (EPA WA) and EFA. The index involving (EPA WA and EFA) was found to be a more effective selection criterion in our herd, as the accuracy of index was more (0.61), in comparison to the index involving EPA MY and EFA. The robustness of selection index was assessed by increasing the relative economic values of included traits by 25 and 50 %, and accuracy of the index remains almost stable without much change. The developed selection strategy involving EPA WA and EFA should be considered for the genetic evaluation of Murrah buffaloes, as it has a potential for maximizing the lifetime reproduction and production performances of the breed. 相似文献

Barley varieties were screened for their efficient drought enduring ability and associated characters which may be useful in breeding programmes. The characters studied were: relative water content, content of proline, chlorophyll stability index (CSI), and percentage grain loss per plant due to water stress subjected to 10 days from jointing to boot stage. Proline and chlorophyll stability index were greatly associated with drought response (r =+0.54; -0.49), flag leaf area (r =+0.69; -0.51) and, to a certain extent, with leaf number (r = -0.35 and +0.34). Among the studied 19 varieties of barley, only three (DL 192, DL 36, DL 3) showed high enduring ability, of these the former two fall in the early, and the last one in the late flowering group. Morphological architecture of DL 192 had gathering type tiller (narrow tiller angle), wider and floppy leaves and it also bears physiological characters (high proline and high relative water content, and low value of chlorophyll stability index) necessary for drought resistance. DL 3 and DL 36 had dispersing type tiller (wider tiller angle) and erect leaf with good leaf area/plant, but unit leaf area was low in DL 3 (relates with shading behaviour reducing water loss). Other relations of drought resistance are briefly discussed in the text. An appraisal of the various traits revealed that high proline content, and low CSI (biochemical characters), earliness, larger flag leaf area and fewer leaves per plant (morphological characters) were directly correlated with productivity of the cultivars under drought conditions. These characters could be used as a guideline for breeding drought resistant cultivars of barley. 相似文献

A pollen selection study for drought tolerance using Poly Ethylene Glycol (PEG) as a selective agent was conducted in sorghum.
Ten genotypes of sorghum suitable for post rainy season were crossed to cytoplasmic male sterile line 104A and three genotypes
to 116A producing 13 hybrids. Two sets of 13 hybrids with and without pollen selection were produced. PEG at 36 per cent was
applied to stigma and stylar tissue one hour before pollination for pollen selection (selective fertilization) and no treatment
for control (nonselective fertilization). Hybrids thus produced through selective and non-selective fertilization were tested
in moisture stress environment during post rainy season. The hybrids obtained through selective fertilization produced significantly
higher mean grain yield compared to hybrids obtained through non-selective fertilization. The results indicate that selective
fertilization through in vivo pollen selection using PEG as selective agent was effective in improving moisture stress tolerance of the progeny in sorghum
genotypes studied. Further, the pollen selection also had influence on plant height, panicle length, panicle width, panicle
weight and grain mass. Thus,the pollen selection had a significant effect on grain yield through its components and developmentally
related traits. Pollen selection for osmoticstress tolerance in sorghum influences the growth and vigour of the plants resulting
in superior progeny in moisture stress environment. The analysis of individual crosses indicated that pollen genotype selection
was able to favour performance of the progeny. However, the pollen selection had positive effect in majority of the hybrids
and the study demonstrates the transmission of the selected trait from pollen generation to progeny.
