MENINGKATKAN LIBIDO DAN KUALITAS SEMEN PEJANTAN KAMBING PERANAKAN ETAWAH (PE) YANG DIBERI PAKAN TAMBAHAN UREA MORINGA MOLASSES MULTINUTRIENT BLOCK (UMMMB)

Abstract

Low libido and semen quality often occur in bucks as a source of semen, which can reduce reproductive efficiency which can affect food security. This study was conducted to evaluate the effect of Moringa leaf in the supplement  feed  the Urea Moringa Molasses Multi-nutrient Block (UMMMB) on libido and the semen quality of the  crossbreed etawah (CE) bucks which were given the main feed of swamp forage. This study used eight CE bucks aged 18.50 ± 1.00 months with a bodyweight of 32 ± 1.49 kg kept intensively in an individual cage for nine weeks, fed with the main feed of swamp grass. Four tails were fed 200g of Urea Molasses Multi-nutrient Block (UMMB) as control and four tails were fed UMMMB additional feeds 200g as treatment. Observation of libido and the semen quality is done once a week for six weeks in the fourth week to the ninth week. The measurement of libido and the semen collection was carried out at 07.00 AM before feeding. The observed variables were compared using the independent sample t-test. Supplementation of the UMMMB  significantly (P <0.05) increased libido  (24.3 ± 3.58 vs 14.51 ± 1.57seconds) and the sperm  total  motility (69.93 ± 1.09 vs 75.47 ± 1.65%) the PE bucks, but not significantly (P> 0, 05) increased the semen volume and sperm concentration (0.78 ± 0.06 vs 0.86 ± 0.09 ml and 2.986 ± 25.02 vs  3.612 ± 39.29 x million/ml). This study shows that the use of Moringa leaves in urea molasses multi-nutrient block plays a role in increasing libido and total sperm motility so that UMMMB can be used as additional feed to increase libido and semen quality of PE bucks.
