Suplementasi Kolin Klorida dalam Ransum untuk Meningkatkan Pertumbuhan Ayam Broiler
Abstract: Cholin
(B-hydroxyethyl-trimethylammonium hydroxide) is a constituent of phospholipids,
can interfere the metabolism process that affects the growth. Sometimes cholin
in a diet does not meet the animal requirement because of its low availability.
The objective of the research was to study the effect of cholin chloride
supplementation in the diets on broiler performance. A completely randomized
design with 4 treatments and 4 replications were used in the experiment on
broiler chicks reared up to 6 weeks of age. The treatment diets were R1
(control), R2 (R1 + 750 mg cholin chloride/kg diet), R3 (R1+ 1,500 mg cholin
chloride/kg diet), R4 (R1+ 2,250 mg cholin chloride/kg diet). All of the
prestarter diets (0-2 weeks of age) contained isocaloric (3,000 kcal ME/kg) and
isoprotein (24.8% crude protein). The starter-finisher diet (2-6 weeks of age)
contained 3,000 kcal ME/kg and 20% crude protein. Supplementation of 750 mg
cholin chloride/kg diet (R2) increased (P < 0.01) body weight gain and final
body weight. Supplementation of 1,500 mg cholin chloride/kg diet (R3) and 2,250
mg cholin chloride/kg diet decreased (P < 0.01) body weight gain, final body
weight, as well as feed efficiency. It was concluded that supplementation of
750 mg cholin chloride/kg diet (containing 1,956 mg cholin/kg in prestarter
diet and 1,791.3 mg cholin/kg in starter-finisher diet) yielded the best
performance of the broilers.
