Performa Kambing Peranakan Etawah Muda dan Produktivitas Induk Laktasi dengan Sistem Pemberian Pakan yang Berbeda di Lahan Pasca Galian Pasir

Abstract

This study aimed to examine the effect of different feeding systems on post-mining of sand land performance of young Peranakan Etawah goat and lactation productivity of Etawah ewe The study used 12 goats (12,592 ± 1,326 kg) within 3-6 months of age. There were two factor of treatment. Treatment one was differences of eating time (W1 = 08.00 a.m to 04.00 p.m and W2 = 02.00 p.m to 04.00 p.m). Treatment two was type of feed (P1 = 100 g/day concentrate and forage, P2 = forage). Protein content of concentrate was 19,32% and forage affered ad libitum. The data were analyzed descriptevely for dry matter intake, feed eficiency and Income Over Feed Cost (IOFC) but the method for daily Body Weight Gain (BWG) used in this study was 2x2 factorial completely randomized design. The results showed that BWG of goats was significantly different among treatment (P<0,01). There was interaction betwent W & P trial. Daily BWG was significantly higher in trial W1 and P1 as well as IOFC with average daily BWG is 74,41 ± 11,89 and IOFC is Rp. 249.666,67. Subsequent study on the lactation productivity Etawah ewe of different feeding systems. This study used 15 goats within 10 goats in lactation two and 5 goats in lactation three. Treatment was differences type of feed (P1 = forage, P2 = forage and food industry waste). The data feed consumption were analyzed descriptevely. Data production and milk quality were analyzed using t test. Dry matter of milk was very significant higher (P<0,01) in ration added food industry waste than ration without food industry waste adition, while protein content and fat in milk was significant (P<0,05).
