Nutrient intake of horses in Thoroughbred and Standardbred stables     

LL SOUTHWOOD  DL EVANS†  WL BRYDEN‡  RJ ROSE 《Australian veterinary journal》1993,70(5):164-168

SUMMARY Twenty-five Thoroughbred (TB) and 25 Standardbred (SB) stables were visited to determine their feeding practices. The ingredients of the main feed of the day for a mature gelding of average size in full training were weighed at each stable. Nutrient content of diets was calculated using published data for the individual ingredients. Results are expressed as mean±sd. The estimated body weight of TB horses was 493±34 kg and 437±32 kg for SB horses. There was considerable variation in diet composition and nutrient intake between stables. The TB trainers fed 11.0±2.4 kg and SB trainers 11.8±2.5 kg per day. The concentrate component of the diet weighed 7.8±1.6 and 7.7±2.3 kg for TB and SB stables, respectively, and the roughage component for TB horses 3.3±1.4 and SB horses 4.1±1.4 kg per day. The digestible energy intake of horses at TB stables was 129±29 MJ per day and at SB stables 132±31 MJ per day. Crude protein intake of TB horses was 1452±363 g and SB horses 1442±338 g per day. There were differences in some feeding practices at TB and SB stables. Standardbred trainers fed more roughage than TB trainers. Standardbred trainers fed chaffed lucerne (alfalfa) and cereal hays as the major roughage, whereas TB trainers fed more hay. The major hay type fed by TB trainers was lucerne, whereas many SB trainers preferred clover hay. Both trainers fed oats as the major grain, but TB trainers fed slightly more maize (corn) than SB trainers. The SB trainers fed barley as part of the concentrate component of the diet, whereas TB trainers usually fed boiled barley and linseed oil in winter only. Although many trainers used vitamin and mineral supplements, this appeared unnecessary in many Instances, especially with respect to Iron. Calcium and NaCI supplementation was necessary for some diets. We concluded that while there was a wide range in feed intake and diet composition for both TB and SB horses, average nutrient intakes were similar to National Research Council (1989) recommendations for horses performing intense work.  相似文献   

Polygalacturonase and β-galactosidase activities in Hayward kiwifruit as affected by light exposure,maturity stage and storage time     

S. Tavarini  E. Degl’Innocenti  D. Remorini  R. Massai  L. Guidi 《Scientia Horticulturae》2009

Softening process and total antioxidant activity were evaluated in kiwifruit differently exposed to light intensity and harvested at two different times (October 10 and November 14). Fruit was stored for 2 months at 0 °C (S1) and then maintained for a week at ambient temperature (S2). The results showed that fruit harvested later presented a faster softening rate during storage than fruit harvested earlier, even if antioxidant activity did not change. Light-exposed fruit showed higher flesh firmness than that of shaded ones. Polygalacturonase activity was higher in kiwifruit maintained for a week at ambient temperature after cool storage and, in particular the highest value was recorded in fruit harvested later. The behaviour of β-galactosidase was different: it did not show changes in fruit harvested later and significantly decreased in light- and shade-exposed fruit harvested earlier.  相似文献

What kind of formation in the multiethnic culture of the European Union of the third millennium?     

Gianfaldoni  D.  Guidi  A. 《Veterinary research communications》2008,32(1):67-70

Even though occidental food production and control systems guarantee a reasonable level of safety for consumers, western countries are facing a growing phenomenon of immigration from all over the world. With this enrichment and the shuffling of cultures and customs in the same places, even alimentary habits undergo an unavoidable evolution, also influencing the commercial trends of society. The growing demand for ethnic products, often of uncertain provenance, composition and manufacturing, has motivated the appearance of illegal trade and markets or improper local productions besides the legal ones, implying a rise in hygienic risks for the consumers. These underground realities, together with the unfilled gap that still exists between different cultures and customs cause significant difficulties in carrying out efficient controls to guarantee sanitary safety for consumers. For this reason, the risks associated with this increasing globalisation must be faced with proper information and a decisive formative strategy must be divided, in order to allow the operator of the whole system and control employees to be acquainted about different raw materials, manufacturing systems, alimentary habits, languages for communication and commercial dynamics which stand beyond the new alimentary trends.  相似文献

役馬的新飼養標準     

吳仲賢 《中国农业大学学报》1956,(2)

一.緒言現行的役馬飼養標準,為數甚多。由於工作的計算困難,大都祇對於某種農業情况,加以大約的估計,因此用量的大小極不一致,而又無適當可行的辦法加以比較,以便抉擇。此中情況,林敦氏(1950)有言,"最好的方法是按照下述的辦法來飼養,如感覺馬的體情退化則增加飼量,如馬有長肥的傾向則減少之"。同樣波波夫亦謂,"必須不斷地注意馬的體况,並根據觀察結果,經常調整馬的日糧"(1954)。似此,則役馬的飼養仍處於一種技術修養的狀態,談不到定額矣。本文的目的在提出一衡量工作的尺度,根據此尺度,測驗各家的標準,並從而求出一比較合理的標準,此標準不但要按照飼養乳牛的辦法,計役授糧,而且要應用簡便,易於實行。此外,不同輕重及種類的工作,經測定各種的常數以後,亦可以納入本方法之中,俟一一論及之。  相似文献   

Shrinkage of artificially dried soil samples collected at different depths in a clay soil     

G. Petruzzelli  M. Pagliai  G. Guidi 《植物养料与土壤学杂志》1980,143(5):518-523

Quantitative variations of shrinkage patterns in soil samples collected at different depths along a “V” shaped crack were estimated. Size distribution of cracks and size distribution of clods were also determined. Slight differences were found in the values of total shrinkage but at increasing depth cracks became larger and the number of dimensional size classes in which cracks were distributed increased. In samples collected at 0-5 cm, and 25-30 cm the largest cracks belonged to the dimensional class 0.8-1 mm while in the deepest samples (65-70cm) the width of largest cracks was 2.0 mm. Along the profile there was a regular increase of clods of the largest size (> 20 mm) from 25 %to more than 50 % for samples collected at the soil surface and those collected at 65-70 cm, respectively.  相似文献   

Cadmium occurrence in soil organic matter and its availability to wheat seedlings     

G. Petruzzelli  G. Guidi  L. Lubrano 《Water, air, and soil pollution》1977,8(4):393-399

Experiments were performed concerning the influence of soil organic matter on Cd availability to wheat seedlings. Cadmium added to soil was bound by alkali soluble humic substances through linkages so strong that it was not removable by seedlings under toxic limit. Cadmium linked by organic matter was principally found in fulvic acids, and after polyamide chromatography of the latter, all fulvic Cd was completely recovered in first fraction which contained the major part of aminoacid compounds. These findings suggest that interactions between Cd and proteic substances, frequently reported in studies on animal tissues, are active in soil too.  相似文献
