Efisiensi Reproduksi Sapi Perah PFH Pada Berbagai Umur Di CV. Milkindo Berka Abadi Desa Tegalsari Kecamatan Kepanjen Kabupaten Malang

The purpose of this experiment was to investigate the effect of different age of Holstein Friesian Cross Breed dairy cows on reproductive efficiency at CV. Milkindo Berka Abadi, Tegalsari Village, Kepanjen Sub District, Malang Regency. The materials of the research used 82 heads of dairy cows which had at least two times of parturition. Data used reproductive data which were collected from Artificial Insemination practices at CV. Milkindo Berka Abadi. Descriptive analysis was used to determine average and deviation standard of Service per Conception (S/C), Days Open (DO) and Calving Interval (CI). Data were analyzed using Multiplet-test. The age of animal influenced significantly (P<0.05) the reproductive parameters e.g. S/C (2.6±1.2 times, 3.6±1.8 times, 4.2±2.8 times and 2.9±2.6 times), DO (184.4±97.2 days, 260.6±159.6 days, 396.9±296.2 days and 263.1±125.2 days) and CI (460.9±97.2 days, 538.8±160 days, 674±296.1 days and 539.7±124.6 days) for the age of 3, 4, 5 and 6 years respectively. It was concluded that the young cows at CV. Milkindo Berka Abadi had more efficient reproductive performance than those for older cows

Analysis of Factors that Affecting the Activities of Anoa (Bubalus depresicornis and quarlesi) Hunting in Donggala District, Central Sulawesi

Wildlife hunting activities, especially Anoa were still done by the community at Sibado Sirenja village, District Donggala District. This activity is conducted to determine the factors that cause the activity of Anoa hunting activities in the community level in increasing household income and food fulfillment. Therefore, the purpose of this study is to determine the factors that influence the occurrence of Anoa hunting activities. The research used descriptive verification method through Structural Equation Modeling (SEM) analysis, data analysis was done with Partial Least Square and SmartPLS software. The result of analysis obtained by determinant coefficient (R2) variables that influence the development of Anoa is the rise of Anoa hunting (Y1) equal to 0623 with value of t-statistic 13,203 and preservation of Anoa (Y3) equal to 0,661 with t-statistic value 13.837 and regulation strategy Y2) 0.600 value of t-statistic value of 7,817. Latent variables that influence the hunt were economic (X1), health (X2) and social culture (X3). The value of R2 of Anoa hunting (Y1) of 0.623 indicates that the variable can be explained by economic variable (X1) with p-value 0.074 (74%), health with p-value 0.566 and social culture with p-value 0.033. Anoa preservation variable (Y3) can be explained by economic variable (X1) with p-value equal to 0.108, health (X2) p-value of 0.835 and socio-cultural variable (X3). While the variable of regulation strategy (Y2) can be explained by exogenous economic variable (X1) with p-value equal to 0.962, health variable (X2) with p-value equal to 0.835 and socio cultural variable (X3) with p-value 0.175.

Kualitas Semen Dan Produksi Semen Beku Pada Bangsa Sapi Dan Bulan Penampungan Yang Berbeda

The purpose of this research was to determine semen quality and frozen semen production of beef cattle at different month collection in Lembang Artificial Insemination Center. Beef cattle strain that used for this research are Aceh, Angus, Brahman, Limousine, Madura, Ongole and Simmental. The research parameter included semen volume, pH, motility of spermatozoa, concentration of spermatozoa, number of spermatozoa, number of spermatozoa motil and number of frozen semen straw. The method of this research using factorial completely Randomized Design and each had 3 replication per treatment. The different of beef cattle have given a significant effect of semen volume (P<0.01), mortility of spermatozoa (P<0.01), concentration of spermatozoa (P<0.01), number of spermatozoa (P<0.01), number of spermatozoa motil (P<0.01) and pH (P>0.05). Different month collection have a significant influence of semen volume (P<0.01), pH (P<0.05), motility of spermatozoa (P<0.01), concentration of spermatozoa (P<0.01), number of spermatozoa (P<0.01), number of spermatozoa motil (P<0.01). Interaction between breed of beef cattle and different month of collection have given a significant influence of semen volume (P<0.01), motility spermatozoa (P<0.01), concentration spermatozoa (P<0.05) and number of spermatozoa motil (P<0.01)

Penampilan Reproduksi Sapi Peranakan Ongole (PO) Dan Sapi Peranakan Limousin Di Kecamatan Sawoo Kabupaten Ponorogo Dan Kecamatan Tugu Kabupaten Trenggalek

The purpose of this study was to evaluate artificial insemination program on the reproduction performance of Ongole crossbred and Limousin crossbred cattle. The materials of the study were Ongole crossbred and Limousin crossbred cattle. Descriptive analysis was used to determine service per conception (S/C), days open (DO), calving interval (CI), conception rate (CR) and calving rate (CvR). Meanwhile, t-test was used to analyse differences among those variables. The study showed that the value of S/C, DO and CI between Ongole crossbred and Limousin crossbreed cattle differed significantly (P<0.05). The average S/C, DO, CI of Ongole crossbred cattle were 1.3±0.32; 156.9±29.33 days; 430±43.72 days respectively. In addition, Ongole crossbred cattle had calving rate (CvR) as well as conception rate (CR) was 74%. Meanwhile Limousin crossbed cattle had 1.5±0.39 of S/C; 172.9±19.21 days of DO; 451.3±19.61 days of CI. Moreover, calving rate (CvR) and conception rate (CR) of Limousin crossbed cattle was 52%. The study concluded that reproduction performances of Ongole crossbred cattle were better than that of Limousin crossbred cattle

Pengaruh Pengencer Tris Aminomethane Kuning Telur Yang Disuplementasi Sari Kulit Manggis (Garcinia Mangostana) Terhadap Kualitas Semen Sapi Limousin Selama Penyimpanan Suhu Dingin 50C

The purpose of this research was to determine the dose of mangosteen rinds juice (0%, 2%, and 4%) in a diluent Tris Aminomethane-egg yolk. The fresh semen was collected once a week using an artificial vagina from five Limousin bulls aged 8 to 11 years old with a body weight of 895-1034 kg. The research method was experimental laboratory using a randomized block design with 3 treatments and 10 replications. If there were significant influences among the variables, it would be then tested by Duncan's Multiple Range test method. The result showed that Tris Aminomethane-egg yolk diluent with 4% of mangosteen rinds juice suplementation had significant differences (P<0.05) on the sperm quality kept for 72 hours in the cold storage in terms of the percentage of sperm motility and sperm viability. It also had a significant difference (P<0.05) on sperm abnormality particularly within the 1st hour. It can be concluded that the addition of 4% mangosteen rinds juice in Tris Aminomethane-egg yolk diluent could protect Limousin bull semen quality (motility, viability and abnormality) after stored for 72 hours at 50C

Study the Changes of Thyroid Hormones Levels Following Major Urological Surgery

This study was designed to evaluate the effect of major surgery on thyroid hormones and thyrotropin in patient undergoing major lower abdominal surgery. The study included fifty patients scheduled for elective major lower abdominal surgery, the serum levels of T3, T4 and TSH were determined one day preoperatively, intraoperative, one day postoperatively, two days postoperatively, and rT3 was determined one day preoperatively, and one day postoperatively. We observed that the levels of (T3, T4, TSH) increased significantly (P0.05). rT3 increased not significant (P>0.05) in one day postoperatively. It has been proposed these changes due to surgical stress that inhibits peripheral conversion of T4 to T3 by inhibiting peripheral 5'-deiodinase activity, also The absence of pituitary response to changes in serum levels of T3 and T4.According to the results of this study there is a transient abnormality in thyroid function tests in patient undergoing elective major surgery and this abnormality due to surgical stress
