SUBSTITUTION OF FISH OIL WITH PALM KERNEL OIL IN DIETS OF Oreochromis niloticus FRY: EFFECTS ON GROWTH, FEED UTILIZATION AND ECONOMIC ESTIMATES

This study assessed the impact of replacing fish oil with palm kernel oil (PKO) in the diet of Oreochromis niloticus fry on growth, feed efficiency and proximate composition. Three isonitrogenous (30% crude protein) and isolipidic (10% crude lipid) diets were formulated using palm kernel oil as a substitute for fish oil at 0% (PKO-0), 50% (PKO-50), and 100% (PKO-100). Two hundred O. niloticus fry with initial weight of 0.80± 0.25g were purchased from Water Research Institute Upper West, Ghana and transported to the Spanish Laboratory of University for Development Studies (Ghana) where they were kept and fed two times a day on commercial diet from Ranaan feed for two weeks. The fry was then stocked in triplicate groups in 60 L tanks (50 cm x 40 cm x 40 cm) at 20 fry per tank. At the end of the eight weeks feeding trial, there was a significant difference amongst the three treatments with respect to final weight, weight gain, feed conversion ratio, and specific growth rate. It was observed that the least mean values for feed intake, protein productive value, protein efficiency ratio, and protein intake occurred in fish fed PKO-0. There was a trend of increasing whole body moisture content as palm kernel oil increased. Fish fed PKO-0 recorded the lowest lipid content (7.48 ± 1.13%) in the whole body. From the economic analysis, it is evident that palm kernel oil is a cheaper source of lipid for tilapia. This study therefore recommends palm kernel oil as a substitute for tilapia diet.

Pengendalian Kualitas Produk Refined Bleached And Deodorized Palm Kernel Oil Di PT Kuala Lumpur Kepong Dumai

Kualitas merupakan salah satu faktor penting dalam aktivitas produksi. Hal ini menuntut perusahaan untuk tetap menjaga kualitas produk yang diproduksinya sehingga produknya dapat diterima konsumen serta mampu bersaing di pasar. PT KLK Dumai merupakan perusahaan yang bergerak di bidang pengolahan Crude Palm Kernel Oil (CPKO). Perusahaan ini masih mempunyai permasalahan pada mutu Refined Bleached And Deodorized Palm Kernel Oil (RBDPKO) dimana produk tidak memenuhi parameter yang telah ditentukan yang disebabkan oleh beberapa faktor. Metode yang digunakan dalam penelitian ini adalah adalah metode Six Sigma. Metode ini terbagi atas 5 tahapan, yaitu Define, Measure, Analyze, Improvement dan Control (DMIAC). Parameter produk dengan persentase cacat tertinggi adalah parameter FFA yaitu 7%, kemudian parameter colour yaitu 5% dan yang terendah adalah parameter Moisture yaitu 1%. Pengujian kapabilitas proses diketahui nilai Cpk FFA 1,62 > 1, nilai Cpk Moisture 2,97 > 1 dan nilai Cpk Colour 1,27 > 1 hal ini menunjukkan bahwa parameter FFA, Moisture dan Colour memenuhi spesifikasi akan tetapi harus dilakukan pemantauan.Faktor yang mempengaruhi kualitas RBDPKO terdiri atas manusia, metode, mesin, material dan lingkungan. Untuk mengatasi permasalahan pada parameter mutu Produk RBDPKO penulis menerapkan metode 5W-1H.

Effect of Palm Oil, Palm Olein, Palm Kernel Oil and Their Blends on the Lipid Profile of Albino Rats

Edible oils play an important role in the body as carriers of essential fatty acids, this essential fatty acids are not produced in the body but gotten from diet we consume. This study examined the effect of palm oil, palm olein, palm kernel oil and their blends (PKO: POL and POL: PKO) on the lipid profile of Albino rats. The aim was to investigate the nutritional and health effects of these oils. Serum was used in the biochemical analysis of lipid profile using Randox Laboratories (England) kit. High density lipoprotein cholesterol in rats fed diets containing unheated and unblended PKO was lower than the recommended range and palm olein and their blends were all higher than the recommended range of 40-59mg/dL. Palm kernel oil fortified diet significantly increased triglyceride levels while; total cholesterol levels were considered to be acceptable except for palm kernel oil and its blends. Palm kernel oil and higher blend of palm kernel oil increased significantly very low density lipoprotein cholesterol above the recommended limit of 2-30mg/dl. Low density lipoprotein cholesterol values in this study were far below the recommended limit for PKO and higher blends of PKO. In conclusion palm oil helps to lower total cholesterol concentration by stimulating the synthesis of protective HDL-C. Palm kernel oil increases total triglyceride and total cholesterol levels.
