Pengaruh penambahan kolin klorida dalam pakan terhadap produksi, total solid, dan persistensi susu sapi perah laktasi
Abstract: The study aimed to
review the effects of choline chloride addition on milk production, total
solid, and persistency in lactating dairy cattle. This experiment was conducted
at Wahyu Agung Dairy Farm, Getasan District, Semarang Regency, Central Java.
The materials used in this study were 8 lactating dairy cattle. The feed given
consisted of napier grass and commercial concentrate (WA Feed) at ratio of
40:60 in dry matter (DM) base at 3.25% BW as basal diet, and mixture of commercial
choline chloride (60%) and corncob (40%). The experimental design used a
cross-over designs with 2 treatments (T0 and T1) and 4 replications in II
periods. The treatments were feed without addition of choline chloride (T0),
and the feed with addition of choline chloride at 30 g/head/day (T1). The
results showed that there was no effect of choline chloride addition in feed on
dry matter intake, being 13.29 and 14.12 kg/head/day for T0 and T1,
respectively. However, milk production was significantly different (P<0.05)
between T0 and T1, being 13.48 and 13.91 l/head/day, as well as in total solid
(T0= 12.61% vs T1 = 13.12%; P<0.05), eventhough there were no significant in
persistency of milk (T0 = 4.17% vs T1 = 2.83%; p>0.05). The conclusions of
this experiment was addition of choline chloride in feed as much as 30
g/head/day could increase milk production and total solid, but did not affect
the persistency milk production.
