The aim of the study was to verify the influence of selenomethionine (SM) supplementation on performance, carcass yield, characteristics of meat quality and Se tissue deposition of finishing pigs. A total of 128 hybrid pigs with an average weight of 76 kg were distributed in randomized blocks according to body weight in eight treatments and eight replicates. The experimental treatments were two Se levels from sodium selenite‐SS (0.3 and 0.6 ppm), four Se levels from SM (0.3, 0.4, 0.5 and 0.6 ppm) and two combinations of SS with SM (SS 0.15 + SM 0.15 ppm and SS 0.3 + SM 0.3 ppm) providing 0.3 and 0.6 ppm Se in the diet respectively. The feeds were based on corn and soya bean meal. After 30 days on test, were analysed the performance indices and the pigs were slaughtered at commercial slaughterhouse. The cold carcass yield, the physicochemical characteristics of the loin meat and the Se content in muscle and liver were evaluated. There was no significant difference in performance indices (p > .05); however, there was a linear effect on the increase in pig carcass yield by increasing SM (p < .05). The use of SM solely or combined with SS provided higher Se deposition in muscle compared to SS (p < .05). The highest Se deposition in muscle occurred for SM at 0.4 ppm (p < .05). The SS provided higher Se deposition in liver (p < .05). The SM presented best results for meat quality compared to other sources (p < .05). The level of 0.4 ppm Se promoted the best results for the indices of yellow, luminosity, cooking loss and pH (p < .05). The use of SM at any level promotes higher oxidation stability of pig meat (p < .05). The supplementation of SM at a level of 0.4 ppm promotes better physicochemical characteristics and higher Se deposition on swine meat.  相似文献

Supplementation with compounds rich in linoleic acid, including sunflower seed supplementation, promotes increase in conception rates in cows. We aimed to evaluate whether the sunflower seed (linoleic acid source) supplementation in beef donor females alters the plasma concentrations of cholesterol, triglycerides, HDL and LDL, increases the number and quality of oocytes, increases the cleavage rates and determines an improvement in number and quality of in vitro produced blastocysts. Thus, Nelore females were divided into two groups of 15 animals to receive supplementation with or without sunflower seed for 57 days. Females underwent follicular aspiration and the oocytes were subjected to in vitro embryo production. There was no difference (p > .1) between control group and group supplemented with sunflower seed on the number of displayed follicles; number of aspired oocytes; recovery rate; cleavage rate; number of embryos; number of blastocysts; embryos number of grades I and II; plasma concentrations of total cholesterol, triglycerides; HDL and LDL. Therefore, sunflower seed supplementation in oocyte donors did not increase the number and quality of oocytes, cleavage rates and the number and quality of blastocysts produced in vitro.  相似文献   

The impact of body site, topical melatonin and brushing on hair regrowth after clipping normal Siberian Husky dogs     

Diaz SF  Torres SM  Nogueira SA  Gilbert S  Jessen CR 《Veterinary dermatology》2006,17(1):45-50

The aims of this study were to determine the impact of body site, vigorous brushing and topical melatonin treatment on hair regrowth after clipping normal dogs. Siberian Husky dogs were randomly assigned to three groups of eight dogs each. All dogs had the lumbosacral region and both lateral thighs clipped. The left thigh and lumbosacral area received no treatment and were compared in all 24 dogs. Eight dogs had the right thigh treated with 0.1% melatonin twice daily for 2 months, and hair regrowth was compared with the left thigh. Eight dogs had the right thigh brushed twice daily for 2 months, and hair regrowth was compared with the left thigh. Eight dogs had neither thigh treated. Hairs were plucked before and 2 months postclipping, and the proportion of hair growth from the original length was calculated and compared as described above. Biopsy samples were collected before and after treatment to determine if brushing induced dermal inflammation and melatonin increased the proportion of anagen follicles. Proportionally, left thigh hairs were significantly longer compared to lumbosacral hairs 2 months postclipping. No significant differences in hair regrowth were noted between the nontreated thigh and the thigh treated with melatonin or brushed. No significant difference in dermal inflammation was noted before and after brushing. No significant differences were observed in the proportion of anagen follicles before and after topical melatonin treatment. Our results showed that the hairs in the lumbosacral region were proportionally shorter than lateral thigh hairs 2 months postclipping. Moreover, topical melatonin and brushing had no impact on hair regrowth after clipping normal dogs.  相似文献   

Blood Supply in the Tongue of Nellore Bos indicus (Linnaeus, 1758)     

J. R. Ferreira  D. J. Nogueira    B. F. Rodrigues    B. F. Alvarenga 《Anatomia, histologia, embryologia》2009,38(2):103-107

Aspects of the vascularization of the tongue of Nellore Bos indicus ( Linnaeus, 1758) were evaluated through the vascular injection technique (with latex-type Neoprene 450, Du Pont do Brasil S.A. and Sulvinil coloring, Glassurit), fixed in formaldehyde at 7% and dissected with magnifying glass. The material was collected at Goiás Carnes Freezer Warehouse in Goiania, Goias. It was found that the deep lingual artery penetrated the lower lateral region of the prominence of the dorsal area of the tongue, advancing rostrally between the hyoid bone and the hypoglossal muscle. In the intravisceral initial third, the artery represents the deep, sinuous continuation branch of the lingual artery, in which path the sublingual artery was stressed in the ventral plan. Then, the artery deepened in the interior of the hypoglossal muscles and genioglossal, supplying dorsal branches (from three to nine) for the lingual torus; from one to five dorsal collateral branches for the lingual cavity; and one or two ventral collateral branches. At the lingual apex, the artery undergoes bifurcation supplying collateral, dorsal and ventral branches with anastomoses between the parallel vessels in the same antimere and between branches of lower caliber hierarchy between opposite antemeres. The large presence of microvessels indicates a significant blood supply to the organ. These results, in comparison with those found in literature, suggest a peculiar vascular pattern for this cattle breed of Indian origin.  相似文献

Process Parameters and Technological Quality of French Rolls Produced with Dry Sourdough to Reduce Sodium     

Amanda de Cssia Nogueira  Caroline Joy Steel 《Cereal Chemistry》2016,93(2):138-144

The search for alternatives for salt reduction in bread is a challenge. This study aimed to evaluate the use of dry sourdough (DS) for the reduction of sodium in French rolls, using a 2² central composite rotatable design. Sodium chloride (NaCl) (0–2.5%) and DS (0–10%, flour basis) were added to the formulations. The reduction of NaCl decreased high‐speed mixing time, proofing time, oven spring, cut opening, and cut height. The addition of DS increased high‐speed mixing time and proofing time and, at higher concentrations, decreased oven spring, cut opening, and cut height. Color parameters also showed effect of DS. Specific volume, shape, and texture of the rolls were not affected by the variables. Thus, the use of DS was shown to be viable for the reduction of sodium in French rolls, because we reached up to 45% salt reduction at concentrations below 5% DS, with desirable technological characteristics.  相似文献   

Secondary succession in a fragmented Atlantic Forest landscape: evidence of structural and diversity convergence along a chronosequence     

Ladivania Medeiros do Nascimento  Everardo Valadares de Sá Barretto Sampaio  Maria Jesus Nogueira Rodal  Ana Carolina Borges Lins-e-Silva 《Journal of Forest Research》2014,19(6):501-513

Changes in physiognomy, species composition and structure, and dispersal mechanisms of canopy and subcanopy plant assemblages were investigated along a chronosequence of three ages: 12, 20, and 50+ years old (=old-growth), three replications in each, in an Atlantic Forest landscape in Northeastern Brazil. Our objective was to investigate whether there is floristic and structural convergence along secondary succession. There were significant differences between secondary and old-growth forests in density and basal area only for the subcanopy. Differences in density between forest ages were noted when the assemblage was analyzed per diameter and height classes. Richness of canopy species of both secondary ages differed from those of old-growth forests. Some dominant species in the canopy of secondary forests showed a significant decrease in density with increasing age, which indicates an ongoing process of floristic changes. The low level of shared species between secondary and old-growth forests supports the idea that species composition is one of the last components to recover during successional process. Zoochory was the most important dispersal guild in species percentage and number, irrespective of stand age. Although regenerating areas can take alternative pathways, our results indicate that secondary Atlantic Forest sites have a high potential for natural regeneration. This recovery is recorded as a physiognomic convergence of the canopy layer in as little as 12 years, and progressive introductions of later successional species into the plant assemblage that lead to convergence in terms of the diversity and richness of the subcanopy and of dispersal guilds just 20 years after abandonment.  相似文献   

Corpus Luteum Development and Function after Supplementation of Long‐Acting Progesterone During the Early Luteal Phase in Beef Cattle     

G Pugliesi  ML Oliveria  SC Scolari  E Lopes  FV Pinaffi  BT Miagawa  YN Paiva  JRG Maio  GP Nogueira  M Binelli 《Reproduction in domestic animals》2014,49(1):85-91

Strategic supplementation of P4 may be used to increase conception rates in cattle, but timing of supplementation in relation to ovulation, mass of supplementary P4 and formulation of the P4‐containing supplement has not been determined for beef cattle. Effects of supplementation of long‐acting progesterone (P4) on Days 2 or 3 post‐ovulation on development, function and regression of corpus luteum (CL) were studied in beef cattle. Cows were synchronized with an oestradiol/P4‐based protocol and treated with 150 or 300 mg of long‐acting P4 on Day 2 or 3 post‐ovulation (6–7 cows/group). Colour‐doppler ultrasound scanning and blood sample collection were performed from Day 2–21.5. Plasma P4 concentrations were greater (p < 0.05) from Day 2.5–5.5 in the Day 2‐treated groups and from Day 3.5–5.5 in the Day 3‐treated cows than in the control group. CL area and blood flow during Day 2–8.5 did not differ (p > 0.05) among groups, suggesting no effect of P4 treatment on luteal development. The frequency of cows that began luteolysis before Day 15 was greater (p < 0.04) in cows treated with 300 mg than in the controls, but there were no differences between non‐treated and 150 mg‐treated cows. The interval from pre‐treatment ovulation to functional and structural luteolysis was shorter (p < 0.01) in the combined P4‐treated groups than in the control cows. In conclusion, was showed for the first time that long‐acting P4 supplementation on Day 2 or 3 post‐ovulation increases P4 concentrations for ≥3 day, has no effect on luteal development, but anticipates the beginning of luteolysis in beef cattle.  相似文献
