This experiment aimed to observe the effect of herbs (Black Cumin,Curcuma zeodharia,Curcuma mangga, and Curcuma aeruginosa) supplementation on milk yield and milk quality (milk fat, milk protein, milk lactosa and mastitis status) in lactating dairy cows suffering mastitis. Twenty cows in 2 nd -4 th lactation suspected mastitis subclinical (++) were used in the experiment. Completely randomized design was used in this experiment with 5 treatments (A. Non Herb; B. Black Cumin; C. Curcuma zeodharia; D. Curcuma mangga, and E. Curcuma aeruginosa) with four replicates per treatment. The collected data were analyzed by analysis of variance and difference between the treatment effects was tested by using Duncan's Multiple Range Test. The results showed that supplementation of herbs significantly increased (P<0.01) milk yield, milk protein, milk lactosa and significantly decreased mastitis status and did not significant affect milk fat.

Free radical levels can be higher than the level of endogenous antioxidants in the body so that uncomfortable conditions in the body of dairy goats could happen. To anticipate this uncomfortable conditions will be given feed supplement (FS) as source of antioxidants (AOX). FS contain mixture pineapple rind meal and antioxidant minerals (AOXM) each 25 ppm Zn and 10 ppm Cu. This experiment was carried out to investigate the effect of feed supplements as antioxidant source on milk quality of dairy goats. Sixteen Etawah dairy goats in the second lactation were used in the experiment that conducted using randomized block design with 4 treatments and 4 replicates. The treatments were R0 (grass + concentrate), R1 (R0 + FS containing 0.04 % AOX), R2 (R0 + FS containing 0.06% AOX), R3 (R0 + FS containing 0.08 % AOX). The data collected were analyzed using Anova. The result of phytochemicals analysis indicated that feed supplement contained flavonoid, polyphenols, sesqiuterpen, mopnoterpen, steroids, quinones and saponins. The results of study showed that there were difference (p<0.05) among treatments on blood and milk cholesterol and milk lactose, but there were no difference (P>0.05) on milk yield, milk fat, milk protein and milk antioxidant. The conclusion of this study was the feed supplements containing 0.08 AOX produced the best response to milk quality of dairy goats.

Agricultural and plantation wastes, especially cocoa plants, have not been widely used, although in some conditions they have potential as animal feed ingredients and raw materials for composting. So needs a  program potential utilization of waste produced by the plant cocoa is cocoa shell waste such as being liquid smoke. Liquid smoke is a natural food preservative. One of the advantages of liquid smoke is antioxidant compounds. This study aims to know the antioxidant activity of cocoa shell liquid smoke on a variety of different water content. This research is an experimental quantitative descriptive method so that an analysis of the antioxidant activity of liquid smoke from cocoa peel is obtained. The results showed that the liquid smoke of cocoa peels at a moisture content of 25%, 20%, 15%, and 10% had strong antioxidant activity because the IC 50 values obtained were below 50 ppm.

bulan; masa kosong (Days Open) 260,63±147,04 hari dan 192,26±114,04 hari; sedangkan selang beranak (calving interval) 548,63±168,30 hari dan 477,26±114,04 hari. Performa reproduksi di kedua daerah ini belum baik karena melebihi jangka waktu optimal untuk ketiga variabel tersebut. Tidak ada perbedaan (P>0,05) antara penampilan reproduksi sapi perah di kedua daerah penelitian. Kata kunci : sapi perah, performans reproduksi, umur beranak pertama, masa kosong, selang beranak

The aim of this study was to determine the effect of giving Cumin (Cuminum cyminum L.), White Turmeric (Curcuma zedoaria Rosc.) and Mango Turmeric (Curcuma mango Val.) on levels of heavy metals lead (Pb) in cow's milk produced. The study was conducted in West Java with experimental method in 16 Fries Holland dairy cows with lactation period of 2-4 months and lactation months of 3-4 months. The design used is simple randomized design with 4 treatments such as Group A (control/no treatment), Group B (Cumin 0.03% body weight), Group C (White Turmeric 0.02% body weight) and Group D (Mango Turmeric 0.06% body weight). Measurement of Pb levels in milk using the method of wet destruction, while Pb measurements on faeces using wet ashing method, by means of Atomic Absorption Spectrophotometry. Based on the researsch results showed that administration of Cumin, White Turmeric and Mango Turmeric have very real effect on reducing levels of heavy metals lead (Pb) in cow's milk produced, with a consecutive decrease 98.36, 99.33 and 99.37% and the very real effect on elevated levels of Pb in faeces by 68.01, 64.52 and 80.54%. Mango Turmeric is the best treatment of three treatment in decreasing lead level in milk.
