Physiologic Evidences Of Good Tolerance Of Concurrent Rumen Fistulation And Duodenal Cannulation In West African Dwarf Sheep

Abstract

Twelve adult West African Dwarf (WAD) sheep of mean age and body weight of 18 ± 1.19 months and 14.69 ± 2 56 kg body weight respectively were used to study the compatibility of concurrent rumen fis ulation and duodenal cannulation with normal life. The compatibility with norma life was assessed by differences in body weight, voluntary feed intake, rectal temperature and some haematological and biochemical parameters for a period of eight weeks between test and contro groups. During the s udy period, all the six animals survived the surgery. There was no significant (p < 0.05) d fference in body weight between the test and control groups for the entire study period (week 1-8). The mean rectal temperature of the test group was significantly (p < 0.05) higher than the control group on week 1(44.6 ± 3.15 0 C), week 2 (43.26 ± 4 14 0C) and week 3 (41.15 ± 6 62 0 C) after implantation. Packed cell volume (PCV) and erythrocyte count (EC) were significantly reduced in the test group within the f rst three weeks (33.19 ± 1 41 to 24.45 ± 1.39% and 7.01 ± 1 34 to 4 37 ± 1.58 x 10 6 µl) respectively. On the contrary, total leukocyte count (TLC), and neutrophils were significantly higher in the test group between weeks 1 to 3 (12.48 ± 4 35 and 31.09 ± 3.67 respect vely) compared to the control (8.06 ± 0.95 and 23.41 ± 2.09 respec vely. Lymphocytes were insignificantly higher in the test group while voluntary feed intake was insigni icantly reduced in the test group throughout the eight weeks. Biochemical analyses revealed that serum creatinine was signi cantly higher in the test group at week 1 (3.62 ± 1.18) and week 2 (3.08 ± 1.44) af er surgery. There was however, no significant difference in serum total proteins during the study period. Serum potassium concentrations were s gni icantly decreased in the test group at week 1 (4.96 ± 1.03 to 1.34 ± 0.04). Sod um was also sign cant y reduced (146.08 ± 3.78 to 96.03 ± 6.21) but on week 3 post imp antation (PI). On the other hand, serum globulin was significantly higher in the test group throughout the study period. Gross observations of incision sites showed adhesions characterized by coalesced tissue granulations. The study has shown that the use of polymetric materials in fabricating rumen fistulae and duodenal cannuale could pave way for increased routine nutritional studies in ruminants particularly in developing countries where the availability of these materials constitute great limitation to research involving rumen studies.

Comparative Evaluation of Midventral and Flank Laparotomy Approaches in Goat

“…Higher values of total white blood cells count and lymphocytes count were recorded in midventral approach at the second week after surgery with significant difference when compared with the flank approach and this could be attributed to high persistent chronic inflammatory response in the course of tissue repair or it could be due to surgical stress because midventral approach is more stressful in relation to surgical positioning than lateral recumbency. Our finding is also in line with those of [ 20 , 21 ] who also recoded elevated values leukocytes count. But [ 8 ] noticed an average total leukocytes value within normal physiologic range after abdominal surgery in dairy cows.…”

“…The packed cell volume (PCV) of the flank approach decreased significantly one week after surgery when compared with midventral approach; this could be due to high intraoperative hemorrhage recorded. This finding was in line with the finding of [ 20 , 21 ], both in a study involving laparotomy with goat; they noted that remarkable hematocrit decreased after surgery with significant difference. [ 8 ] also reported significant decrease in PCV in postoperative abdominal surgery in bovine.…”

Haematologic tolerance of a rumen fistulation protocol in Udaramsata Tertiary Institution Livestock Teaching and Research Farm, Kaduna State, Nigeria

“…Acute neutrophilia and subsequent lymphocytosis as shown in Table 2.0 suggest physiologic response to inflammation and enhanced immune response (cell mediated immunity). In localized traumatic conditions such as rumenotomy, leucocytosis due to lymphocytosis and neutrophilia has been reported (Weisis, 1984;Hassanein et al;1988;Aka et al,2006). Tissue destruction, irrespective of its cause will produce an increase in the number of circulating neutrophils.…”
