Abstract

Estrus synchronization and artificial insemination (AI) for productive female cattle through feed improvement aimed to increase the availability of seed quality. This study was conducted in July Kede Dua Village in July Subdistrict, Bireuen District. Nine cattle at the ages of 2 to 2.5 years old were used as samples. The design of the study was a Randomized Block Design (RBD) with 3 treatments and 3 replications. There were three ration treatments, namely: P = Sync+AI+natural grass+elephant grass, J = Sync+AI+50% rice straw+15% Gliricidia+35% (natural grass+elephant grass)+concentrate+mineral blocks, and S = Sync+AI+40% rice straw + 20% Gliricidia + 40% (natural grass + elephant grass) + concentrate + mineral blocks. The observed variables were the percentage of estrus, the percentage/rates of pregnancy, the weight of female cattle during pregnancy, feed intake and feed conversion. The results showed that hormonal injections of PGF2α on the first day of J treatment generated 100% of estrus while P and S treatments generated 33,33% of estrus. At the second injection, there was an increase up to 66,67% on the 12th day in P and S treatments. The average of feed consumption during the study in each treatment was J = 28.23 kg/cow/day, S = 27.08 kg/cow/day, P = 25.60 kg/cow/day. There was a significant difference in daily weight gain caused by the difference in ration quality in each treatment.
