Impact Of Using Different Stocking Rates Of Goats Under Pine Plantation On Plant Species Occurrence And Animal Productivity, Anthony S. Kumi, India Howard, Ronald C. Smith, Nar Gurung, Alphonso Elliott

Professional Agricultural Workers Journal

Abstract

The study assessed the impact of using different stocking rates of goats under pine plantation on plant species occurrence and animal productivity. It was conducted on an 11 year-old loblolly pine plantation site in Epes, Alabama from July to October 2011. Thirty-six Kiko crossbred male goat kids of 4 to 5 months of age were assigned to different stocking rates, namely, low (4 goats/acre), medium (8 goats/acre), and high (12 goats/acre) with three replications each. Forage composition, animal daily gain (ADG) and blood urea nitrogen (BUN) were monitored. Bahia grass (Paspalum notatum) was the most dominant grass …

The aim of this study was to determine the changes in serum nonesterified fatty acid (NEFA), serum ß-hydroxybutyric acid (ß-HBA), triglycerides, Ca, Na, and other metabolites (bilirubin, glutamate dehydrogenase (GLDH)) in the blood of grazing, healthy goats at the time of parturition. Blood samples were taken weekly from the jugular vein of 11 goats, starting at week 2 antepartum (ap) until week 9 postpartum (pp). NEFA and ß-HBA concentrations increased from week 2 ap to 2 weeks pp. The increase in NEFA level was not significant; however, the ß-HBA levels were higher (P < 0.05) 2 weeks pp compared to the levels at 2 weeks ap. Triglycerides were recorded at maximum levels (P < 0.05) 2 weeks ap, with the lowest concentrations at 3 weeks pp. Bilirubin levels consistently increased up to 7 weeks pp, followed by a decrease. However, these changes were not significant. Similarly, GLDH activities increased until week 8 pp. A significant difference (P < 0.05) was recorded between the 1st week and 8th week pp. Ca and Na levels were lower during the 1st week pp and increased at 3 weeks pp. The results show that there are characteristic alterations of some metabolic blood parameters in goats around the time of parturition, which may be related to physiological changes.

Diurnal Variations Of Renal Activity In Goats, Zbigniew Muszczynski, Ewa Skotnicka, Dorota Jankowiak

Turkish Journal of Veterinary & Animal Sciences

Research was conducted on 12 clinically healthy 4-year-old White Nobel goats. Renal activity examinations were carried out with the use of clearance methods where inulin was used as a testing substance to determine the level of glomerular filtration. The results allowed determination of inulin clearance, endogenic creatinine, sodium, potassium, and chloride levels. Filtered load, tubular resorption, and excretion in urine of sodium, potassium, and chlorides were marked. The research revealed diurnal variations of renal activity in goats. Most of the rhythms' acrophases occur in the phase of activeness between 1200 and 1600 hours. The resorption rhythm of potassium in the …
