2023-10-29T11:09:32+07:00

The birth and growth of dairy calves are important factors in the dairy cattle business. The growth of calves and mothers needs to be monitored in production management so that they can produce good seeds or milk according to the expected quality. This study aims to determine the effect of feeding depolarized katuk leaves on the performance of calves from cow consuming depolarized katuk. 21 gestation cows were three groups of seven cows each, the control group (feed complete),CF-DKPo (complete feed added with Depolarized Katuk Powder), CF-DKPe (complete feed added with Depolarized Katuk Pellets). As a feed addition, 100 grams of depolarized katuk feed were provided daily to each head which is given in the morning by mixing it with the morning feed. The treatment was served during at 10 days before calving day and up to 7 days birth. The research data consisted of gestational days data, daily gain data and calf body weight data from 0 – 90 days old. Data analysis on gestational age, body weight, and average daily gain of calf were by using one-way analysis of variance (ANOVA), and if there is a difference, continue with further testing (Dunnett’s test) using SPSS. The results showed that there were differences in birth weight and body weight in calves from mothers that were given depolarized katuk leaves. Calves from broodstock that consumed depolarized katuk leaves in pellet form had higher weights compared to the control and BKD treatments. Significant differences occurred in birth weight and calf ADG for each treatment. Katuk leaves that have been depolarized can be added to feed to help calves grow bigger.

Rabbits are meat-producing livestock with high productivity. Rabbit meat has high nutritional content and is good for health. The DKI Jakarta Government through the Center for Animal Health and Livestock Services (Pusyankeswannak) has opened the Bambu Apus Livestock Park. This research was conducted to determine the productivity of bambu apus rabbit carcasses as broiler rabbits to support urban farming programs in DKI Jakarta. Ten of bambu apus rabbits (five males and five females), ten of new zealand white rabbits (eight males and two females) and 17 rexsi grinak rabbits (eight males and nine females) were used. The body weights of the rabbits ranged from 2000 to 3000 g per head. This research has obtained Ethical Clearance (Balitbangtan/Center for Animal Husbandry Research BRIN/NRm/01/2022). Rabbits were slaughtered according to Islamic Syar’i and the carcass were cutting according to the commercial cut. A completely randomized design with a 3 x 2 factorial pattern (sex and type of rabbit) was used with carcass productivity and meat physical properties as variables. Bambu apus rabbits have good carcass productivity (Carcass Percentage, Meat Bone Ratio), meat on commercial cuts (Loin and Hindleg) and carcass quality (pH, tenderness, Water Holding Capacity and cooking losses) which were the same as new zealand white rabbits and rexsi agrinak rabbits as the broiler rabbit. Bambu apus rabbits have good carcass production and carcass meat quality so they have the potential to be developed into broiler rabbits in support of urban farming programs.
