Effect of haylage made of kume grass standinghay fermented with liquid palm sugar and local chicken manure on semen quality and scrotum circumference of male local goat

Abstract

This experiment was conducted to study semen quality and scrotum circumference of male local goat fed kume grass standinghay fermented for 30 days using liquid palm sugar as carbohydrate source and local chicken manure as nitrogen source. Twenty male local goats of one year old with an average initial body weight of 10 ± 1.5 kg were employed in this experiment. Experimental design used in this experiment was the completely randomized design consisted of 5 treatments with 4 replicates. Those treatments were R0 = kume grass standinghay, R1 = R0 fermented with 3 % liquid palm sugar, R2 = R0 fermented with 3 % liquid palm sugar and 15 % local chicken manure, R3 = R0 fermented with 3 % liquid palm sugar and 30 % local chicken manure, and R4 = R0 fermented with 3 % liquid palm sugar and 45 % local chicken manure. Percentage of both liquid palm sugar and local chicken manure was based on the weight of kume grass standinghay. The diets were offered eight to ten times daily. Variables measured were quality of semen namely pH, volume, and consistency of semen, spermatozoa concentration and motility, live spermatozoa, and scrotum circumference. Results indicated a significantly effect of treatments (P<0.05) on semen consistency, spermatozoa concentration, motility, viability, and scrotum circumference as well, meanwhile no significantly effect was observed on pH and semen volume. However, there was no significantly difference effect between R3 (30 % local chicken manure in ration) and R4 (45 % local chicken manure in ration) or in other word both treatments were relatively have the same effect.
