Effect of Dietary Frying Fat, Vegetable Oil and Calcium Soaps Of Palm Oil on the Productive Behavior and Carcass Yield of Broiler Chickens

Vegetable oils (VO) and animal fats are conventional lipid sources used in feed formulations. Frying fats (FF) and calcium soaps of palm oil (CaSPO) are low-cost lipid sources. This study evaluated the productive performance of broiler chickens fed diets with CaSPO in substitution for VO or FF. Two hundred, 1-day old male broiler chickens were allocated in a randomized design with factorial arrangement (22). Diets included 2 lipid sources (FF and VO) and 2 CaSPO levels (0 and 50%). The study had two phases (starter and finisher) of 21 days each. For the starter phase there was no effect (p>0.05) of dietary treatments on the chickens productive performance. For the finisher phase birds fed diets with FF had higher feed intake and feed conversion ratio (main effect; p 0.01) than those fed diets with VO. Over the 42-day feeding period animals fed FF had higher feed conversion ratio (main effect; p=0.02) and tended (p=0.08) to show higher feed intake than those fed diets with VO. The CaSPO substitution for VO or FF had no effect (p>0.05) on the productive performance of broiler chickens. There was no influence of treatment on carcass yield. The drumsticks plus thighs were higher (main effect; p 0.01) in birds receiving VO than in those receiving FF. The interaction (fat source*CaSPO) was not significant (p>0.05). These results may indicate that VO is superior to FF and CaSPO may substitute for VO or FF without affecting productive performance of broiler chickens. Lipid source showed small influence on carcass characteristics.(AU)

Hand-Assisted Laparoscopic Nephrectomy for Live Donor Kidney Transplantation.

INTRODUCTION: The live donor nephrectomy is an unusual surgical procedure as it is performed on healthy individuals. It is important to make the procedure as safe as possible without compromising the health of the donor and graft function. JUSTIFICATION: In Mexico during 2014, 2610 kidney transplantations performed, and 1862 grafts were from living donors. OBJECTIVE: We describe our experience with hand-assisted laparoscopic nephrectomy on live donors for kidney transplantation. MATERIALS AND METHODS: We present a descriptive and observational study in which all living donors who completed the study protocol for renal transplantation are included. RESULTS: From September 2006 to July 2015, there were 238 hand-assisted laparoscopic nephrectomies with live donors; 227 (95.37%) were performed on the left side and 11 (4.63%) on the right side. Of donors, 54.1% were females. The average values for the variables analyzed were age 38.17 years, 25.94 BMI, creatinine 0.82-1.13 mg/dL pre- and postoperative month respectively, length of stay 4.95 (range 2-8), warm ischemia 5.07 (range 3-13) minutes, surgical time 168.85 minutes (range 90-306), and transsurgical bleeding 139 055 mL (range 25-650). One patient was reoperated for abdominal pain and bloating without evidence of pathology, attributing it to metabolic ileus. Two patients were converted to open surgery; 1 by technical problems with the laparoscopic equipment and the second by bleeding from the renal vein, both with good results. DISCUSSION AND CONCLUSIONS: Laparoscopic nephrectomy is a safe method that allows kidney donors to have a speedy recovery without modifying the survivals of renal grafts.
