Effect of Supplementation Purslane (Portulaca oleracea) as a Source of Alpha-Linolenic Acid on Production Performance and Physical Quality of Egg of Laying Hens

Abstract

Abstract. The aim of the study was to evaluate the effects of inclusion plant source of n-3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the diets of layers on production performance and physical quality of eggs. A total of 125 Hy-Line Brown hens (38 weeks old) were placed at individual cages and assigned to five dietary treatments. The dietary treatments were supplemented with 0, 1.5, 3.0, 4.5 and 6.0% purslane meal. Laying hens were fed for five weeks following a seven day adaptation period. Water and feed were provided ad libitum. Feed intake (FI) measured weekly and feed consumption ratio (FCR) was calculated at the end of the trial. A total of 25 egg yolk samples of day 35 (n = 5 egg yolks for each treatment) were collected to analyse physical quality of eggs. The data were analyzed using analysis of variance. Differences between treatment means were further analyzed using Duncan's New Multiple Range Test (DMRT). Results showed that the incorporation of plants rich in ALA did not modify FI, FCR, and egg production. Supplementation of purslane meal in the diets had no effect on physical quality of eggs, including egg weight, yolk weight, albumen index, yolk index and Haugh Unit (HU). The average of egg weight and yolk weight were 60,5 and 15.3 g, respectively. Diet containing purslane meal increased yolk colour. In conclusion, laying hens that fed diet supplemented with purslane meal rich in ALA improved yolk colour and did not change the production performance of the laying hens or the qualities of the eggs.

Tujuan dari penelitian ini adalah mengetahui pengaruh lemak n-3 dari tanaman dalam bentuk alphalinolenic acid (ALA, 18:3n-3) pada pakan ayam petelur terhadap performa produksi dan kualitas fisik telur. 125 ayam Hy-Line Brown (38 minggu) ditempatkan pada kandang terpisah dan diberi 5 perlakuan pakan yang diberi tambahan 0, 1,5, 3,0, 4,5 dan 6,0% tepung krokot. Ayam petelur diberi pakan selama 5 minggu dan 7 hari adaptasi. Pakan dan air diberikan ad libitum. Asupan pakan (FI) diukur setiap minggu dan rasio konsumsi pakan (FCR) dihitung pada akhir percobaan. Sejumlah 25 sample kuning telur pada hari ke 35 (n= 5 kuning telur dari setiap perlakuan) diambil untuk dianalusa kualitas fisiknya. Data dianalisa menggunakan Analysis of Variance (ANOVA). Perbedaan antara perlakuan kemudian dilanjutkan dengan Duncan's New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa suplemen tanaman kaya ALA pada pakan tidak mempengaruhi kualitas fisik telur, termasuk berat telur, berat kuning telur, indeks albumen, indeks kuning telur dan Haugh Unit (HU). Rataan berat telur dan berat kuning telur berturut-turut adalah 60.5 dan 15.3. Pakan mengandung tepung krokot meningkatkan warna kuning telur. Disimpulkan bahwa ayam petelur yang pakannya disuplementasi dengan tepung krokot yang kaya ALA meningkatkan warna kuning telur tetapi tidak mengubah performa produksi ayam telur atau kualitas telur.

The Quality of Meat, Carcass, and Cut Yields of Broiler Chicken Fed Diets Containing Purslane Meal Rich in Omega-3 Fats

“…The greater the energy content of the feed, the higher the abdominal fat weight can be. The influence of purslane meal in chicken diets on the fatty acid profiles of chicken meat has been reported by Kartikasari et al (2023). The amount of ALA, docosahexaenoic acid (DHA) and total n-3 PUFA in the broiler meat increased when alpha-linolenic acid (ALA)-rich purslane meal was added to the diets up to a level of 6%.…”
