Acute cortisol responses of calves to scoop dehorning using local anaesthesia and/or cautery of the wound   总被引：1，自引：0，他引：1  

SP SYLVESTER  DJ MELLOR  KJ STAFFORD  RA BRUCE  RN WARD 《Australian veterinary journal》1998,76(2):118-122

Objective To measure plasma cortisol responses in calves dehorned using a scoop after administration of local anaesthesia and/or cautery of the wounds.
Design A physiological study with controls.
Procedure There were six treatments: control handling with and without local anaesthesia, dehorning, dehorning after local anaesthesia, dehorning followed by wound cautery, and dehorning after local anaesthesia followed by wound cautery. Blood samples were taken before and after dehorning.
Results Dehorning caused an increase in plasma cortisol concentrations, which decreased a little to plateau values and then declined to pretreatment values 3 to 4 h after dehorning. The peak was smaller after local anaesthesia was administered but when its effects wore off, cortisol concentrations increased and thereafter were similar to those in the dehorned animals. The combination of local anaesthesia and cautery resulted in a plasma cortisol response similar to those in control calves with or without local anaesthesia.
Conclusions If plasma cortisol concentrations reflect the distress being experienced by the calves, then local anaesthesia reduces the acute distress for about 3 h after dehorning but not during the subsequent 3 to 4 h. Combining local anaesthetic and cautery prevented the significant increase in plasma cortisol following dehorning and may eliminate the acute distress caused by scoop dehorning.  相似文献   

Management of inappetant sheep during export by sea     

RT NORRIS  CL McDONALD  RB RICHARDS  MW HYDER  SP GITTINS  GJ NORMAN 《Australian veterinary journal》1990,67(7):244-247

In the first of 2 experiments, a simulated voyage was conducted to examine the effects of various treatments on bodyweight change and feeding frequency of inappetant sheep at the end of lot-feeding (non-feeders). The treatments, applied during simulated shipping, were: normal quantities of feed and length of troughs; extra trough length; extra feed. Adult Merino wethers (n = 108) were used in each treatment. A voyage to the Middle East was then conducted to establish whether shipboard mortality could be reduced by separating non-feeders (n = 305) from feeders (n = 5,620) late in the feedlot hase and housing the groups separately aboard ship. A control group of non-feeders (n = 215) mixed with feeders (n = 5,732) was used for comparison. Bars (marker bars), containing a coloured dye, were attached to feed troughs to mark sheep that fed. Most non-feeders (82%) began eating when placed in shipping pens in both studies. However, there was no significant difference in percentage of sheep that fed between non-feeders given extra trough length or extra feed compared with non-feeders given standard management at any stage of simulated shipping. There was no significant difference in mean bodyweights between treatment groups on days 1, 8 and 15 of simulated shipping. Differences in bodyweight on d 22 were probably associated with different levels of gut fill. Death rates were not significantly different in separated and control groups (1.1%, 0.9%, P = 0.6) in the voyage of 14 d to the Middle East.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献   

Determination of Feeder Cell‐Based Cellular Niches Supporting the Colonization and Maintenance of Spermatogonial Stem Cells from Prepubertal Domestic Cat Testes     

JI Yun  HJ Park  MH Park  MS Kim  JH Choi  E Lee  SP Gong  JM Lim  ST Lee 《Reproduction in domestic animals》2014,49(5):705-710

Recently, isolation and in vitro culture of putative spermatogonial stem cells (SSCs) in the domestic cat have been conducted. However, the cellular niche conditions that facilitate the establishment and long‐term maintenance of feline SSCs (FSSCs) have not been described. Therefore, we investigated the type of feeder cells used to stimulate colony formation and growth of FSSCs among the various factors in the FSSC niche. Spermatogonial stem cells isolated from feline testes were cultured on mitotically inactivated testicular stromal cells (TSCs) derived from cats, dogs and mice, and mouse embryonic fibroblasts (MEFs). The formation and growth of colonies derived from SSCs cultured on each type of feeder cell were identified at passage 0, and the morphology, alkaline phosphatase (AP) activity and expression of SSC‐specific genes in surviving colonies were investigated at passage 4. Among these diverse feeder cells, TSCs from cat showed the greatest colony formation, growth and maintenance of FSSCs, and SSC colonies cultured by passage 4 showed a typical dome‐shaped morphology, AP activity and expression of SSC‐specific genes (NANOG, OCT4, SOX2 and CD9). Accordingly, these results demonstrate that feline TSCs could be used as feeder cells to support the establishment and maintenance of SSCs from domestic cats.  相似文献   

Increase in Growth,Productivity and Nutritional Status of Wheat (Triticum aestivum L.) and enrichment in Soil Microbial Population Applied with Biofertilizers Entrapped with Organic Matrix

To find effective alternatives to reduce the application of conventional urea (CU), a conventional biofertilizer (CB) preparation (charcoal mixed Azotobacter chroococcum and Bacillus subtilis) and the same biofertilizers entrapped in an organic matrix consisting of cow dung, rice bran, dried powder of neem leaves, and clay soil in 1:1:1:1 ratio and 25% (w/w) saresh (plant gum of Acacia sp.), named as super granules of biofertilizers (SGBF) were applied to cultivate wheat (Triticum aestivum L. cv. ‘WH-711’) in experimental plots. The results revealed that the efficacy of commercially available charcoal mixed biofertilizers could not prove as effective alternative to CU, whereas the same dose of biofertilizers entrapped in the organic matrix, SGBF, resulted in a significant increase in growth and productivity of wheat. It appears that SGBF prepared and applied in this study is an effective organic alternative to the urea for wheat cultivation in semi-arid subtropical agro-ecosystems.  相似文献   

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

S. Singh    I. P. S. Ahlawat  K. N. Ahuja 《Journal of Agronomy and Crop Science》1993,171(5):343-349

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.  相似文献   

Increase in growth,productivity and nutritional status of rice (<Emphasis Type="Italic">Oryza sativa</Emphasis> L. cv. Basmati) and enrichment in soil fertility applied with an organic matrix entrapped urea     

Manoj Kumar  Kuldeep Bauddh  Manish Sainger  Poonam Ahlawat Sainger  Jay Shankar Singh  Rana Pratap Singh 《Journal of Crop Science and Biotechnology》2012,15(2):137-144

Field experiments were conducted to evaluate the effects of eco-friendly organic matrix entrapped urea (OMEU) on growth, productivity, and yield of rice (Oryza sativa L. cv. Basmati) and soil enrichment in the paddy field at Rohtak (Haryana) located near Delhi. The OMEU prepared in granular form contained cow dung, rice bran (grain cover of Oryza sativa), powder of neem leaves (Azadirachta indica), and clay soil (diameter of particles < 0.02 mm) in 1:1:1:1 ratios and saresh (plant gum of Acacia sp.) as binder along with half of the recommended dose of commercially available soluble urea (free urea; FU). Single basal application of OMEU showed an increase in plant growth in terms of fresh and dry weights, root length, root, leaf and tiller numbers, soluble protein, total N and ammonium in leaves, productivity in terms of grain and straw yield, and nutritional and microbial activities of field soil over free form of urea and no fertilizer application. Nutritional status of rice grains was also improved over the free urea and no fertilizer controls. Our data indicate that OMEU, which is low cost and based on bio-degradable, non-toxic, and locally available agro-waste, can be attempted to replace the conventional use of soluble urea in rice.  相似文献
