Species co-occurrence and nestedness pattern in Shasha forest reserve were investigated with a view to determining the effect of interactions to species contribution. Three distinct sites (Gmelina arborea plantation, undisturbed forest, and Pinus carribaea (plantation) were selected in the forest reserve. Four 25 m × 25 m plots were established in each of the site within the forest reserve. Species enumeration, identification,, and distribution into families of the standing vegetation were carried out. Woody species represented the most diverse life form. Plant species diversity was highest in UF and lowest in Gmelina plantation. Differences in woody species composition among the three forest types were determined by non-metric multidimensional scaling (NMDS) analysis, analysis of similarity (ANOSIM), and similarity of percentages. Using z-score and NODF (a nestedness metric based on overlap and decreasing fill). Three modules were detected and modularity score Q = 0.2. The composition analyses (NMDS and ANOSIM) revealed a significant difference in the woody species composition among the forest types. Our research may contribute to understand species assemblage in one of the diverse forests of Africa. Current work highlighted species occurrence in Shasha forest and highlighted the importance of non-random pattern which could serve as framework for conservation perspective. 相似文献

The pilei (caps) and the stipes (stalks) of the button and early open-cap (cup) stages ofLentinus subnudus, Psathyrella atroumbonata andTermitomyces striatus were assayed separately for their proximate and mineral composition. The differences observed in the contents of some of the proximate components seem to be related to species and mushroom parts.P. atroumbonata was richest in crude and true protein,L. subnudus was richer in crude fiber, ash and carbohydrates. Mineral contents appeared to be dependent on type and parts of the mushrooms analysed. The three mushrooms were good sources of magnesium, zinc and iron.L. subnudus contained between 14.83 and 20.00 ppm of iron,P. atroumbonata contained between 20.01 and 22.09 ppm andT. striatus contained between 17.13 and 22.93 ppm of iron. The pilei ofP. atroumbonata andT. striatus are very good sources of zinc. Zinc contents for the pilei ofP. atroumbonata were 63.81 and 64.94 ppm respectively. Zinc contents forT. striatus were 90.45 and 92.49 ppm respectively. 相似文献

Grain amaranth was evaluated for its ogi making quality. Amaranth, which produced lower (70%) yield of ogi than corn (80%), had higher protein content of 12.2% for its ogi than that of corn with a corresponding value of 6.7%. Nutrient losses were lower for amaranth than corn ogi. Amylograph pasting viscosity showed that amaranth ogi had slightly higher peak viscosity and lower setback value than corn ogi. It was apparent that amaranth grains would be suitable for ogi manufacture. 相似文献

Despite several studies carried out to investigate the effects of access to pasture on poultry performance, there is a dearth of information on the comparative benefit of grass and legumes. This study investigated the effects of rearing systems [deep litter system (DL), deep litter with access to legumes (LP) or grass (GP) pastures] on the performance of ISA Brown layers. Two hundred and forty 12‐week‐old pullets were housed for this study. They were reared until 60 weeks of age. Eighty birds were assigned to each treatment; each treatment had four replicates of 20 birds each. Two birds per replicate were slaughtered at weeks 20, 35 and 58 for determination of the weights of liver, ovary, oviduct and the number of follicles. Daily egg production records were kept from the day of first egg to 42 weeks in lay. Body weights were recorded weekly. Results indicated that at 20 weeks of age, the hens kept in the LP had higher (p < 0.05) ovary weight (g) (34.98 ± 1.4), oviduct weight (52.55 ± 2.28) and oviduct length (cm) (49.73 ± 11.34), and higher number of large yellow follicles (3.75 ± 1.31) and small yellow follicles (12.75 ± 5.17) than those in the GP (0.83 ± 0.02, 1.68 ± 0.19, 16.38 ± 1.14, 0.00 and 0.00), and DL (1.03 ± 0.11, 1.48 ± 0.48, 14.43 ± 0.58, 0.00 and 0.00) respectively. The age (days) at first oviposition was earlier (p < 0.05) in the LP (139.25 ± 0.85) than that in the GP (146.75 ± 0.48) and DL (146.75 ± 0.48). The hen‐day egg production was lower (p < 0.05) in GP (74.19 ± 1.25) than that in the DL (78.82 ± 0.78) and LP (79.93 ± 1.13) at mid‐laying phase. Concentrate feed intake was lower (p < 0.05) in LP and GP than DL suggesting economic benefit. It was concluded that access to LP enhanced the performance of layers than DL and GP as indicated by the parameters measured. 相似文献

Intravenous regional analgesia (IVRA) has been achieved in twelve West African Dwarf (WAD) goats in a total of 35 trials with 2 per cent lidocaine hvdrochloride without any significant complications. Experimental analgesia was effected 25 times on the limbs of seven goats. Analgesia was also produced 10 times on the limbs of five goats and a major orthopaedic procedure (amputation) performed on the anaesthetized limbs and digits. The analgesia produced was found to be adequate for the procedure. The comparative values of this method of regional analgesia are discussed. 相似文献

The present study investigated the immunolocalization of the progesterone and oestrogen α receptors in the uterine horns of the African giant rat during the oestrous cycle. The progesterone and oestrogen α receptors were demonstrated in various cellular constituents of the endometrium, myometrium and perimetrium. The intensity of progesterone and oestrogen α receptor immunostaining in the endometrial and myometrial layers of the uterine horns varied during the oestrous cycle. The intensity of oestrogen α receptor immunoreactivity in the luminal epithelium was high during pro‐oestrus, oestrus and dioestrus. Progesterone and oestrogen α receptor immunoreactivity in the endometrial epithelia was absent during metoestrus. Moderate to strong immunostaining for the progesterone and oestrogen α receptors was demonstrated in the myometrial smooth muscle cells during pro‐oestrus, oestrus and dioestrus. The intensity of progesterone and oestrogen α receptor immunostaining in the myometrial smooth muscle cells was low during metoestrus. Stromal cells in the perimetrium consistently expressed progesterone and oestrogen α receptor immunoreactivity throughout the oestrous cycle. The findings of the study indicate that in the giant rat the immunolocalization of the progesterone and oestrogen α receptors, in endometrial and myometrial regions of the uterine horns, varies during the oestrous cycle. 相似文献

OBJECTIVE: To determine whether 3 variations of the 1,9-dimethylmethylene blue (DMMB) assay yield comparable results when measuring sulfated glycosaminoglycan (sGAG) concentrations in equine synovial fluid (SF). SAMPLE POPULATION: 25 samples of SF collected from affected joints of 13 horses and 13 samples of SF collected from nonaffected (control) joints of 4 horses. PROCEDURE: Sulfated glycosaminoglycan concentrations were measured by the direct spectrophotometric (ie, Farndale), microplate, and indirect DMMB assays in samples of SF collected from normal and affected joints and in samples digested with nucleases, papain, and hyaluronidase. RESULTS: All 3 assays reacted similarly to standard solutions of sGAGs and digestion of SF samples with nucleases, papain, and hyaluronidase. Nucleic acids were not important interfering substances, and papain and hyaluronidase could not be used interchangeably to digest SE All 3 assays proved to have satisfactory precision (SD < 10%), but each DMMB assay resulted in significantly different measures of sGAG in equine SF. CONCLUSIONS AND CLINICAL RELEVANCE: Samples of SF should be digested with papain or hyaluronidase prior to measurement via DMMB assay. Researchers currently are unable to compare clinical information when variations of the DMMB assay are used, because each DMMB assay yields substantially different sGAG concentrations in SF. Of the 3 assays examined here, we recommend use of the direct spectrophotometric DMMB assay. 相似文献

The biological value of 5 mushroomsChlorophyllum molybditis, Psathyrella atroumbonata, Termitomyces robustus, Termitomyces striatus andVolvariella esculenta from our collection of wild edible mushrooms were determined using weanling rats.C. molybditis supported rapid growth with PER (2.63) higher than the casein control (2.50).P. atroumbonata was average in biological performance (PER 1.50) whileT. robustus andV. esculenta did not support growth at all. Rats onT. striatus dried at 60°C for 48 h lost weight rapidly and showed pathological signs of toxicity by the second day. All rats on this died died by the fourth day of the experiment. When the diet ofT. striatus dried at 90°C for about 8 h was fed, the rats gained weight marginally but all survived. Prolonged storage ofT. striatus at 60°C for 5–8 weeks also seemed to detoxify the poisonous component such thatPER andNPR values were 0.8 and 2.0 respectively. 2 pairs each of adult rats fedC. molybditis andTricholoma lobayensis diets for 10 days were mated. Rats ofC. molybditis diet gave 5 and 6 litters each and only one of these litters seemed to have retarded growth. Rats onT. lobayensis diet did not produce any litters for 14 weeks but the female produced off-spring when mated with control male rats. 相似文献

Effects of rumen-protected methionine and lysine on ruminant performance and nutrient metabolism 总被引：3，自引：0，他引：3
Four trials were conducted to determine the effects of supplemental rumen-protected methionine (RPMet) and lysine (RPLys) on lamb N metabolism and steer feedlot performance. In trial 1, 20 Suffolk-sired, crossbred lambs (avg weight 32 kg) were fed diets containing no supplemental methionine (Met) and lysine (Lys), .03% RPMet, .05% RPLys or .03% RPMet + .05% RPLys. Lambs fed .03% RPMet + .05% RPLys had a 33% increase in N retention compared with lambs fed no supplemental Met and Lys. In trial 2, to verify the protection and availability of these amino acids, five Targhee lambs (avg weight 35 kg) were fed corn-soybran flake diets supplemented with urea and were assigned in a 5 X 5 Latin square to one of the following treatments: 1) control; 2) .03% RPMet + .05% RPLys offered in the diet; 3) .03% RPMet + .05% RPLys abomassally infused; 4) .03% non-protected Met + .05% non-protected Lys offered in the diet and 5) .03% Met + .05% Lys abomasally infused. Treatments 2, 3 and 5 decreased (P less than .05) urinary N (g/d) and increased N retention (P less than .05) compared with the control diet (treatment 1). Increases (P less than .05) in plasma Met and Lys concentrations indicated that the amino acids were protected and available for animals at the site of absorption. In trial 3, 40 crossbred Angus steers (avg weight 247 kg) were fed diets composed of 53% corn silage and 47% concentrate and supplemented with soybean meal to 11.3% crude protein. Steers that were fed diets containing .19% RPMet + .11% RPLys had greater daily gain (P less than .05) than those fed diets containing no supplemental amino acids, .11% RPMet + .01% RPLys, and .15% RPMet + .06% RPLys (1.39 vs 1.23, 1.22 and 1.20 kg/d, respectively). Similar improvements in feed conversion resulted and increases in plasma Met concentrations followed the same trend. In trial 4, 40 crossbred Angus steers (avg weight 368 kg) were fed corn grain-corn silage diets supplemented with urea. Treatments were: no supplemental amino acids; .05% RPMet + .01% RPLys; .10% RPMet + .04% RPLys; and .15% RPMet + .07% RPLys. No differences in steer performance resulted due to supplemental RPMet and RPLys (P greater than .05). The results of these trials suggest that the RPMet and RPLys used in this study are protected from ruminal degradation, are available post-ruminally and can improve lamb N balance and growing steer performance. 相似文献
