Penelitian ini bertujuan mengetahui pengaruh penambahan vitamin E dan mineral Zn terhadap kualitas semen kambing Boer. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan empat perlakuan, yakni P0= tanpa penambahan vitamin E maupun mineral Zn; P1= pemberian vitamin E 50 IU/ekor/hari; P2= pemberian mineral Zn 25 mg/ekor/hari; P3= pemberian vitamin E 50 IU/ekor/hari dan mineral Zn 25 mg/ekor/hari. Penelitian menggunakan 12 ekor kambing berumur 3 tahun, masing-masing perlakuan menggunakan 3 ekor kambing. Data yang diperoleh dianalisis menggunakan analisis ragam dan dilanjutkan dengan uji beda nyata terkecil (BNT). Hasil penelitian menunjukkan bahwa pemberian vitamin E dan mineral Zn serta kombinasi keduanya tidak memengaruhi volume semen kambing Boer, tetapi berpengaruh terhadap motilitas dan persentase spermatozoa abnormal (P<0,05) dan terhadap persentase spermatozoa hidup (P<0,01). Pemberian mineral Zn dan campurannya dengan vitamin E mampu meningkatkan kualitas spermatozoa kambing Boer.

The study was conducted on dairy cattle livestock at Lampung Province in July - August 2012, aiming to determine the prevalence of liver worms. Disease in livestock caused by liver worm infections are called Fasciolosis. Fasciolosis is an important parasitic disease because it can cause high economic losses. The research method was the census method. Data retrieval were 125 dairy cattle faecal samples from people's dairy farms in Lampung Province. The datas obtained were analyzed descriptively. Examination of faecal samples was carried out at the Lampung Veterinary Center using the Sedimentation Test. The results showed the prevalence of liver worms in dairy cattle in Lampung Province was 12.00%, 15 dairy cattle those were positively infested by liver worms. The highest dairy cattle prevalence in West Lampung Regency at 33.33%, while the lowest prevalence is in dairy cattle in Bandar Lampung City and Tanggamus Regency at 0%. Keywords:  Dairy Cattle Livestock, Lampung Province, Liver Worms, Prevalence, Sedimentation Test

The aim of this research was to determine the effect of farmer management on Bali cattle reproduction efficiency in Pringsewu Regency PENDAHULUANSapi Bali memiliki banyak keunggulan yaitu cepat berkembang biak, tingkat kesuburannya/fertiltasnya tinggi, mudah beradaptasi dengan lingkungannya, dapat hidup di lahan kritis, mempunyai daya cerna yang baik terhadap pakan dan persentase karkas yang tinggi. Kemampuan lain yang dapat diandalkan untuk pengembangan populasi Sapi Bali adalah interval kelahiran yang cukup baik.

The objectives of the study were (1) to know there was or no interaction between soaking time in bay leaf and type of carcass to the physical quality of broiler meat; (2) To know the duration of optimum immersion for the physical quality of the muscles of the breast and thighs. This research was arranged using Completely Randomized Design (RAL) with factorial pattern. The first factor is the length of meat immersion in bay leaf solution, namely: P0: control; P1 (20 minutes); P2 (40 minutes); P3 (60 minutes). While the second factor is a piece of carcass, namely: K1 (thigh) and K2 (chest). Each treatment was repeated 3 times. The research variables were pH of meat, WHC, and cooking loss. The data obtained were proceed to variance analyze and further tested by BNT  Test for length of  immersion and Tukey test for carcass type at 5% level of significant. The results showed that there was no interaction (P>0,05) between soaking time and carcass cut. The duration of immersion had no significant (P>0,05) effect on pH, WHC, and cooking loss. Carcasses cut of thight and breast have a significant effect (P<0,05) on pH and cooking loss, but are not significant (P>0,05) for WHC. The pH value of the thigh meat is significantly (P<0,5) higher than the breast, but the cooking loss is lower. Keywords :  Bay Leaf, Breast, Thight, Broiler, Physical Quality

The aim of this research was to find out the effect of probiotic on blood cholesterol in laying hens. Materials used were laying hens (Isa Brown strain) 43 weeks old and ration using probiotics. This research was conducted by using completely randomized design (CRD). The advanced research was done with testing the local probiotic with various concentration treatment, they are P0 (ration without probiotic), P1 (ration + 1% local probiotic), P2 (ration + 2% local probiotic), and P3 (ration + 3% local probiotic) with 5 time repetitions and in every repetitions consists of 2 chicken. Variables that were observed in the advance research were laying hens’s blood cholesterol that consists of total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, and total leucocyte. The level of total cholesterol on P0, P1, P2, and P3 were 129.00±38.26, 116.00± 26.53, 121.00±33.72, and 137.00±52.53 mg/dL (P>0.05) respectively; the HDL level were 50.60±16.47, 35.80±11.28, 59.40±19.74; 56.80±30.56 mg/dL (P>0.05); the LDL level were 100.20±49.53, 39.20±17.14, 104.60±51.23, and 96.80±66.22 mg/dL (P>0.05), respectively; the trigycerides level were 862.00±355.5, 533.00±146.1, 829.00±242.6, and 810.00±304 mg/dL (P>0.05), respectively; and leucocyte count were 22.00±1.72, 21.00±3.79, 31.00±3.99, and 34.00±3.55 x103 mm3 (P<0.01), respectively. In conclusion, the administrtion of local probiotic do not effect the blood cholesterol of layer chicken.
