After 5 generations breeding, the two main selected traits such as total number of born and age at 100 kg weight was 12.17 piglets/litter and 165.18 d, respectively. The genetic improvements per generates was 0.156 and -2.198, respec- tively. The breeding objects of the new Yorkshire dam line with high prolificacy were basically reached. It indicated that the methods and index could be used in pig breeding.展开更多

In this study, field studies were carried out in Tabebuia rosea to generate clonal planting stock regeneration using three rooting medium at a location in Central Kerala, Peninsular India, for three consecutive years from October 2014 till June 2016 at four months regular intervals. Three IBA concentrations, viz., 200, 500 and 1,000 ppm, have been used and the data obtained was evaluated using SVI method in order to establish the suitable medium, which gives the maximum rooting results. Control cuttings did not record rooting in any of the trials. The high SVI was obtained when stem root cuttings planted in root trainers with coir pith compost （RTCP） for all the three concentration of IBA applied. Sprouting percentage was marked up and the delay in completion of sprouting/rooting initiation decreased by the use of IBA treatment.展开更多

METHODS: The rehabilitation therapy included enteral or parenteral nutrition, glutamine, recombinant human growth hormone and rehabilitative diet. From January 1997 to July 2000, twenty - seven patients with short bowel syndrome received the treatment. The average age of the patients was 38.5 +/- 19.3 years, and the length of residual small intestine ranged from 15 to 80 cm, with an average of 46.8 +/- 23.4 cm. The ileocecal valve was preserved in 14 cases, and the average time between the onset of short bowel syndrome and the rehabilitation therapy was 86 +/- 105 days. RESULTS: After the treatment, nutritional status of the patients improved markedly, and intestinal absorptive capacity improved. Eight patients were followed up for more than 2 years, among whom 4 (50%) were weaned from total parenteral nutrition. Thirteen patients were followed up for more than 1 year, and 10 patients (76.9%) were weaned from total parenteral nutrition. CONCLUSIONS: Rehabilitation therapy for short bowel syndrome can improve patient nutritional status effectively and promote intestinal adaptation, providing a new hope for these patients. The therapeutic effects are related to the length of the residual small intestine, patients age and duration between massive intestinal resection and start of the treatment. Early initiation of rehabilitation therapy promotes intestinal adaptation and increases patients ability to wean from total parenteral nutrition.展开更多
