<p>This study aims to determine of the reproductive performance of beef cows consists are Simpo<br />cow, Limpo cow and PO cow reared on the livestock. The research was conducted by survey on beef<br />cattle 60 head in the District Mojogedang, Central Java Province from December 2014 through<br />February 2015. The research parameter is post partum estrus (PPE), post partum mating (PPM),<br />service per conception ( S / C), days open (DO). Results of the study were analyzed descriptively.<br />Reproductive performance of Simpo cow, Limpo cow and PO cow are consecutive PPE: 3:56 ± 0.73<br />months, 3.93 ± 0:40 months, and 6.75 ± 4.68 months, PPM: 3.85 ± 0.70 months, 3.79 ± 0:51 months,<br />and 4:42 ± 1.23 months, S / C: 1.45 ± 0:20 times, 1.74 ± 0:07 time, and 1:38 ± 0:38 times, DO: 5:33 ±<br />0:58 months, 8:44 ± 4.65 months, and 9:27 ± 5.93 months, CI: 14:33 ± 0:58 months, 14:44 ± 0.66<br />months, and 14:44 ± 0.66 months. The conclusion shows that the reproductive performance of the<br />Simpo cow, Limpo cow and PO cow in District Mojogedang appears that the value of post-partum<br />estrus (PPE) and post partum mating (PPM) is panjang.Service per conception (S / C) is high. Days<br />open (DO) and calving interval (CI) are both still long.</p>
Universitas Pamulang merupakan perguruan tinggi swasta yang maju dan berkembang yang terdapat pada Kota Tangerang Selatan. Tentu Universitas Pamulang memiliki banyak aset sebagai penunjang kegiatannya. Namun saat ini Universitas Pamulang belum memiliki sistem informasi internal untuk mengontrol aset-aset yang dimiliki. Belum adanya sistem informasi manajemen aset tersebut akan mengalami kesulitan dalam penelusuran data-data aset. Solusi untuk mengatasi permasalahan yang ada, membutuhkan sebuah sistem informasi manajemen aset yang dapat menjalankan pengelolaan aset menjadi lebih efisien dan terstruktur, serta memudahkan dalam pendataan jumlah aset, pendataan aset berdasarkan kondisinya, pengelompokan aset berdasarkan jenisnya dan mempermudah dalam melakukan penelusuran data-data aset. Pengembangan sistem yang digunakan yaitu waterfall. Model ini terdiri dari requirement analysis, system and software design, implementation and unit system, system testing, operation and maintenance. Tools yang digunakan dalam penelitian ini adalah system operating windows 10 pro 64 bit, sublime text 3, dan database yang digunakan sebagai penyimpanan data adalah xampp. Hasil akhir penelitian ini menghasilkan sebuah Sistem Informasi Manajemen Aset Pada Universitas Pamulang Berbasis Web.
Climate change occurs because of the greenhouse gas effect. Methane from livestock accounts for 44% of methane emissions in the air, which comes from fermentation from the rumen and from feces. Many attempts have been made to reduce methane production in the rumen, including feed management. This study aims to improve the quality of complete feed fermentation with the addition of different grass source of FJLB (fermented juice of epiphytic lactic acid bacteria). The treatments consisted of T0 (Control, without FJLB), T2 (FJLB from Napier grass), T3 (FJLB from King grass). Complete feed consists of rice straw, rice bran, soybean meal, pollard and corn. The pH value of the silage with the addition of FJLB was lower than that of the silage without the addition of FJLB. The highest acetic acid production was at T3, 8.76 ppm. Meanwhile, the number of lactic acid bacteria was 5.4; 6.3 and 7.6 CFU/ml, for T0, T1 and T2, respectively. Meanwhile, ammonia production was not significantly different. The conclusion of this study is the addition of FJLB from napier grass and king improves the quality of fermentation compared to without the addition of FJLB. Good fermentation quality will improve digestibility in the rumen and is expected to reduce methane production, which is one of the greenhouse gases that causes climate change.
Background and Aim: Pleomorphic adenoma gene 1 (PLAG1) encodes a multifunctional transcription factor that controls many genes and pathways and is associated with cattle body weight and measurements. This study aimed to evaluate the association between PLAG1 polymorphisms with body weight and measurements in Bali cattle. Materials and Methods: A total of 87 Bali cattle, consisting of 48 bulls and 39 heifers at the Breeding Center for Bali Cattle, were used as the population in this study. Cattle were 2 years old and kept semi-intensively in the pasture. Phenotype data consisting of body weight, withers height, body length, chest girth, waist height, and chest depth were measured. Birth weight data were obtained from birth records, and weight gain, adjusted weaning weight, and yearling weight were calculated using formulas. Blood samples were taken from the jugular vein as much as 5 mL, and genomic DNA was isolated using the salting-out method. Polymerase chain reaction (PCR) was performed to amplify three target polymorphisms, namely, g.48308 C>T, g.32212 (19 bp indel), and g.45233 T>C. The presence of a 19 bp indel was determined by direct observation of the PCR product on a 2% agarose gel. Two other polymorphisms were detected by PCR-restriction fragment length polymorphism using the restriction endonuclease enzymes SacII and BclI. PLAG1 genotype and phenotype associations were analyzed using a general linear model. Results: The results showed that two of the target polymorphisms in PLAG1 did not vary. The DD genotype indicated by 123 bp of PCR product was the only genotype identified for g.32212 19 bp indel, and TT genotype was the only genotype found for g.45233 T>C single-nucleotide polymorphism (SNP). Conversely, g.48308 C>T SNP was found to be polymorphic. In addition, the g.48308 C>T polymorphism of PLAG1 was significantly associated with body length of Bali cattle. Cattle with the CC genotype had a greater body length than the other two genotypes. Conclusion: The g.48308 C>T SNP in PLAG1 was associated with Bali cattle body length characteristics. This finding could be used as a basis for selecting Bali cattle based on body length characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
