The aim of this experiment was to investigate the effects of multivitamin nanoemulsion on growth performance, immune function, antioxidant ability, intestinal tissue structure and cecal microecol. of growing Rex rabbits. A total of 150 healthy weaned Rex rabbits at the age of 30 days and similar body weight were selected, and randomly divided into 5 groups with 3 repetitions in each group and 10 rabbits (half male and half female) in each repetition. Rabbits in control group I were fed a granulated feed containing vitamins (100% nutritional standard), normal drinking water; rabbits in control group II fed the same granulated feed with control group I, but the drinking water added Twain-80+glycerol (the contents of them were the same as test group II). Rabbits in test groups were fed the granulated feed without vitamins, and test groups I, II and III were added multivitamin nanoemulsion including 80%, 100% and 120% nutritional standard vitamins in drinking water. The experiment lasted for 61 days including a 5-day preliminary period and a 56-day test period. The results showed as follows: compared with control group I, 1) on day 1 to 28, the diarrhea rate and diarrhea mortality were significantly reduced in control group II and test group I (P<0.05), on day 29 to 56, the average daily feed intake was significantly reduced in test groups II and III (P<0.05), while the feed/gain was not significant difference (P>0.05). 2) The thymus index was significantly reduced in test groups I and II (P<0.05), the appendix length was significantly reduced in control group II and test group II (P<0.05), and the liver index was significantly increased in test groups I and III (P<0.05). 3) The blood total antioxidant capacity in test group II and blood superoxide dismutase activity in control group II were significantly increased (P<0.05). 4) The villus height of ileum was significantly increased in control group II (P<0.01), the crypt depth of ileum was significantly reduced in test group I (P<0.05), and the villus height/crypt depth of ileum was significantly increased in all test groups and control group II (P<0.01). The lymphocyte cell proportion in simple columnar epithelium of ileum was significantly increased in control group II (P<0.05). 5) The relative abundances of Firmicutes, Ruminococcaceae and Ruminococcaceae UCG-014 in cecum were significantly reduced in test group II (P<0.05). It is concluded that adding multivitamin nanoemulsion containing the nutritional standard of 100% into the drinking water can enhance the immune function and antioxidant ability, improve the intestinal tissue structure and cecal microecol. of growing Rex rabbits. In the experiment, the researchers used many compounds, for example, Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate (cas: 137-08-6Category: alcohols-buliding-blocks).
Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate (cas: 137-08-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Category: alcohols-buliding-blocks
