Produktivitas Kambing Peranakan Etawah yang Diberi Ransum Berbasis Jerami Padi Fermentasi
Abstract: Rice straw as one of
agriculture by product has low nutritive value. Fermentation of rice straw
increased its nutrient digestibility and palatability. Present experiments
aimed to study the effect of feeding rations composed of concentrate and ground
fermented rice straw supplemented with urea and probiotic. The first trial was
conducted to study the apparent digestibility of experimental diets in 18
Etawah-grade bucks with 1-1.5 year age and initial body weight of 30.18 ± 8.38
kg. The second trial was conducted to study the effect of feeding experimental
rations on reproduction, milk yield and its quality in 24 Etawah-grade does
with 1 to 3 years age and initial weight of 35.75 ± 5.72 kg. The rations were
as follows; KJP = concentrate + chopped fermented rice straw; KJG = concentrate
+ ground fermented rice straw; KRG = concentrate + elephant grass. A completely
randomized design was applied in both nutrient digestibility and performance
trials. In both trials, the rations were offered twice daily. Does and kids
were weighted once in two week. Does were milked manually once a week for 3
months post partum. Milk was sampled for determination of its specific gravity,
protein, fat and solid content. Gestation length, litter size, birth weigth and
weaned weight were recorded. Dry matter (DM) and crude protein (CP) intake, and
apparent digestibility of DM did not differ significantly among treatments.
However, apparent digestibility of CP in goat offered KJG was lower (P <
0.05) than those of KRG and KJP. DM and CP intake of does was higher (P <
0.05) for the KRG treatment but those were not differ between KJP and KJG
treatments. Gestation length, litter size, the body weight of does during pregnancy
and lactation, the body weight of kids from birth to weaning, milk yield and
quality of milk were not different ammong tretaments. These results suggested
that fermented rice straw can be used to substitute the elephant grass.
