Diabetes mellitus is a chronic metabolic condition that causes persistent hyperglycemia due to insulin action or secretion. Regular physical exercise has been reported to improve glycemia and lipid profile in diabetes. However, literature is scare on the effects of swimming exercise on the serum levels of adiponectin and glucose 6 phosphatase in Wister rats with diabetes This study therefore, investigated the effects of swimming exercise on adiponectin, glucose 6-phosphatase and lipid profile in male Wistar rats with streptozotocin-induced diabetes. This study was carried out on 25 male Wistar rats grouped into five groups (n=5/group): group 1=control, group 2=diabetes, group 3=diabetes treated with metformin, group 4=non-diabetes and swimming exercise, group 5=diabetes and swimming exercise. Animals in groups 2, 3, and 5 were induced with Streptozotocin (STZ) 50 mg/kg intraperitoneally. After 72 hours of diabetes induction, animals with a blood glucose level of ≥ 200 mg/dl were confirmed diabetics and used for the study. Group 3 animals were treated with metformin 200mg/kg giving orally for 28 days. Animals in groups 4 and 5 were subjected to swimming exercises for 5-10 minutes during the first week until they could swim freely for 30 minutes. The animals were then allowed to swim 5 days per week for 28 days. Swimming exercise for 28 days significantly reduced blood glucose, glucose-6-phosphatase (G6Ppase), Lactate dehydrogenase (LDH), Total cholesterol (TC), and Low-density lipoprotein (LDL) levels but caused significant increase in adiponectin and High-density lipoprotein (HDL) levels in diabetic rats compared with untreated diabetic rats. There was a significant decrease in triglyceride (TG) of diabetic animals caused by swimming for 28 days. This study demonstrated that swimming exercise for 28 days may help lower glucose level and improve insulin sensitivity by increasing adiponectin level and decreasing G6Pase activity in diabetic rats. Also, swimming exercise may help improve lipid profile in diabetic rats.

: The study investigated the effect of different somatic cell count (SCC) classes on milk production traits and growth of Zaraibi does and kids at three distinct physiological stages during lactation. A total of 150 milk samples obtained from 50 goats at milk peak, kids weaning, and meeting periods (days of 50, 100 and 150) were analyzed. The goats were selected based on strict criteria, including the same age, kidding date, low milk SCC, and no udder problems. The goats were divided into three classes based on overall milk SCC values: SCG1 (≤315x10 3 cells/mL), SCG2 (316-335x10 3 cells/mL), and SCG3 (>335 x10 3 cells/mL). The results showed that although there were significant differences between SCC1 and SCC2 classes in SCC and log SCC at different stages of lactation, there were no significant differences in milk production and composition. The daily milk yield decreased significantly with increased SCC level (> 335x10 3 cells/mL), and the highest milk losses were observed. The milk composition followed the same pattern of significant differences among SCC classes during different lactation stages, with the highest values observed in the highest SCC class (> 335x10 3 cells/mL). The daily milk yield decreased gradually with increasing lactation stage, while SCC values increased gradually. The does’ body weight did not change significantly by lactation stage. Overall, the findings suggest that SCC level of > 335x10 3 cells/mL has a significant effect on milk production and composition, but not on growth traits of Zaraibi does’ and kids during different stages of lactation. These findings could be useful for dairy farmers to manage their herds and optimize milk production to produce high-quality dairy products.

Wheat (Triticum aestivum L.) is the most widely cultivated crops in Ethiopia. However, wheat production is very low due to many factors. Of these, disease like stripe rust of wheat is the main constrained biotic factor and cause great yield losses. The field experiment was conducted at three hot-spot locations of wheat rust diseases in the zone namely; Sinana, Selka, and Agarfa during the 2019 cropping season to evaluate the effectiveness of newly introduced fungicide for the management of yellow rust disease of wheat. Variety Kubsa, which is susceptible to the three wheat rusts were used. The trial was laid out at three locations with non-replicated plots. Two systemic fungicides (Comet plus and Rex®Duo) and untreated plot (control) were used as a treatment. A significant difference (P<0.05) was observed between fungicide treatments and unsprayed plots on yellow rust severity, grain yield, thousand kernel weight, and hectoliter. Based on field observation and analyzed data results revealed that the newly introduced fungicide found to be effective in controlling stripe rust of wheat. Thus, Comet plus 475 G/L EC is recommended as an alternative fungicide for the management of stripe rust of wheat in wheat-growing areas of the country.

Striga hermonthica, an obligate root hemi-parasite, is a massive biological constraint that hinders maize (Zea mays L.) production in western part of Kenya particularly when susceptible varieties are used. Use of Imazapyr resistant hybrids coated with small doses of imazapyr herbicide offers potential for management of Striga hermonthica and increase maize production. A study was conducted to evaluate the effectiveness of Imazapyr Resistant Maize (IRM) and selected striga tolerant varieties on S. hermonthica management and yield of maize. Field trials were conducted during two successive cropping seasons (2018 and 2019) at Alupe Research Station (artificial inoculation), farmer’s field in Rangwe (natural infestation) and Koibatek Agricultural Training College (striga free) in Busia, Homa Bay and Baringo Counties respectively. The genotypes were evaluated in randomized complete block design with three replication. Test materials comprised of two IRM (H528IR, FRC425IR), two striga tolerant (KSTP94, GAF4), five susceptible commercial hybrids (DK8031, H513, DUMA43, DH04, Haraka 101) and two local landraces (Shipindi, Nya Uyoma). All striga and crop data collected were subjected to analysis of variance and means separated using Tukey’s HSD test. Results showed that IRM varieties significantly (P≤0.05) reduced number of emerged striga plants by 56 and 69% compared to the local landraces and commercial hybrids, respectively. Similarly, IRM varieties produced 50.3 and 79.5% higher grain yields compared to striga tolerant (KSTP94 and GAF 4) and susceptible hybrids, respectively under striga infestation. However, the grain yields recorded at Koibatek ATC (striga free) were 67 and 70% higher than at the Rangwe and Alupe sites, respectively. These findings show that use of Imazapyr resistant technology in maize production contributes to improved striga management and enhances maize grain yields. This technology can be integrated with other measures to contain striga in infested areas.

This study evaluated the efficacy of a single gonadotropin-releasing hormone (GnRH) agonist on day 12 or human chorionic gonadotropin (hCG) on day 7 post-mating on pregnancy rate (PR) of repeat breeder buffaloes. Buffaloes (n=21) in heat were naturally mated, and divided into three groups (7 in each). Animals in the 1st group (G1) were i.m. injected with 5 ml GnRH on 12-day post-mating, while those in G2 were i.m. injected with 1500 IU of hCG on day 7 post-mating. In G3, animals were kept as control. Results show that PR was higher (P<0.05) in G1 (71.428) and G2 (57.142) than G3 (28.571). The peak of serum P4 was recorded (P<0.05) on day 15 in G2, and day 18 in G1 and G3. On days 21 and 24 post-mating, P4 was the highest (P<0.05) in G1, followed by G2, and the lowest in G3. Average CL diameter increased (P<0.05) CL in G1and G2 compared with G3 on days 15 and 18 post-mating. The concentration of P4 was higher in pregnant than in non-pregnant animals on different post-mating days, regardless of treatment. The concentration of P4 was the highest in pregnant of G2, and the lowest in non-pregnants of G3, being more obvious from 18 to 24-day post-mating. Injection of repeat breeder lactating buffaloes with 5 ml GnRH or 1500 IU hCG on day 12 and 7 post-mating, respectively, improved P4 production and pregnancy rate. GnRH treatment reduced the early embryonic loss showing the highest pregnancy rate to increase the farmer economy.
