Livestock farming is an effort to breed livestock to obtain benefits or results in the form of products and income. The success of a livestock business depends on three elements commonly referred to as the production triangle, namely seeds, feed, and management. In addition, the techno-socioeconomic characteristics of livestock farmers greatly influence the development of livestock businesses and will later affect the income of livestock farmers. The aim of the research was to examine the injection of the prostaglandin F2α hormone on the estrus response and pregnancy in Ongole crossbreed and Simental crossbreed cows reared using intensive and semi-intensive rearing systems. The data obtained will be analyzed using analysis of variance (ANOVA) and if there is a real effect, continue with further testing with Duncan's Multiple Range Test. The results of research on the percentage of estrus after the first and second injection of the prostaglandin hormone can be seen in the table. The highest percentage of estrus was in the S1P2 treatment with a percentage value of 80% and the lowest percentage value was in the S2P1 and S2P2 treatments with a percentage value of 40%. The percentage of estrus after the second injection, the percentage value for all treatments increased and the percentage of estrus was highest in the S1P2 treatment with a value of 100%. The average value of onset of estrus after the second injection of the PGF2α hormone was lower than the first injection. The longest duration of estrus in the treatment after the first PGF2α hormone injection was in the S1P2 treatment with an average of 24.75 hours, while the longest duration of estrus in the treatment after the second PGF2α hormone injection was in the S2P1 treatment with an average of 25 hours. PO cattle and Simental crossbreeds injected with PGF2α gave no different estrous responses. Intensive and semi-intensive rearing systems provide no different estrous responses. Raising PO cows using a semi-intensive rearing system injected with PGF2α provides an estrous response and high pregnancy rates (60), to be one of techniques to breed cattle of PO cow and have good impact to the success of a livestock business

Joper chickens are breeds of kampung chickens, Bangkok chickens, or other local breeds of chickens separated from purebred chickens. In addition to genetic factors and feed management, the use of natural constituents as feed additives can affect the meat quality of super hens. Feed additives are ingredients that do not include food substances that are added to the stove in small amounts and are aimed at spurring growth and increasing feed efficiency. The existence of various studies in the selection of feed raw materials that produce quality feed additives that are easy to use and cheap to meet the needs of super rural chickens are moringa leaves. The design used in this research was a Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatment consisted of T0 (Ration does not contain Moringa leaf flour), T1 (Ration contains 6% Moringa leaf flour), T2 (Ration contains 9% Moringa leaf flour), T3 (Ration contains 12% Moringa leaf flour), The parameters observed were feed consumption, body weight gain and feed conversion. The results showed that Moringa leaf flour had a significant effect on feed consumption, body weight gain and feed conversion. The best results were obtained in treatment T1, namely the ratio containing 6% Moringa leaf flour, which was able to increase feed consumption by 367.46 grams, body weight gain by 88.62 grams and feed conversion ratio by 4.16.

ABSTRACT. One is the obstacles faced by cattle breeders is the emergence of diseases caused by environmental influences, such as infestation with gastrointestinal nematode worm parasites (digestive tract worms) so that rearing results are non optimal. Due to this, it is necessary to create a model and strategy for controlling diseases that are often affected, especially those caused by environmental conditions, both from the micro environment (climate) and the macro environment (maintenance management) and this is a necessity in order to obtain maximum production and productivity. The goal of this study was to see how environmental conditions affected the presence of gastrointestinal nematode worms in cattle. This study focused on the prevalence and severity of gastrointestinal nematode worm infestation in cattle in Aceh Province's lowland and highland environments. The research was conducted between February-August 2017 in three lowland districts ( 200 masl) with a sample 307 tail and three highland districts ( 600 masl) with a sample 205 tail. According to the study's findings, topographic variations, wet days, and rainfall all had an impact on the prevalence and degree of gastrointestinal nematode worm infestation in cattle (lowland environments had a higher prevalence and degree of infestation than upland environments (P0,05). In the meantime, lowlands maintenance management seemed riskier than highlands maintenance management (P0.01).Pengaruh faktor lingkungan terhadap infestasi nematoda gastrointestinal pada sapi di Provinsi AcehABSTRAK. Salah satu kendala yang dihadapi para peternak sapi adalah munculnya penyakit yang disebabkan pengaruh lingkungan, seperti adanya infestasi parasit cacing nematoda gastrointestinal (cacing saluran pencernaan) sehingga hasil pemeliharaan tidak optimal. Oleh sebab itu, perlu dibuat suatu model dan strategi pengendalian penyakit yang sering terkena dampaknya, terutama yang disebabkan oleh kondisi lingkungan, baik dari lingkungan mikro (iklim) maupun lingkungan makro (manajemen pemeliharaan) dan menjadi suatu keharusan supaya mendapatkan produksi dan produktivitas yang maksimal. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh faktor-faktor di lingkungan terhadap kehadiran cacing nematoda gastrointestinal pada sapi. Secara khusus penelitian ini menganalisis prevalensi dan derajat infestasi cacing nematoda gastrointestinal pada ternak sapi di lingkungan dataran rendah dan dataran tinggi Provinsi Aceh. Penelitian dilaksanakan antara bulan Februari-Agustus 2017 pada tiga kabupaten dataran rendah (200 mdpl) dengan jumlah sampel 307 ekor dan tiga kabupaten dataran tinggi (600 mdpl) dengan jumlah sampel 205 ekor. Hasil penelitian menunjukkan bahwa faktor lingkungan seperti perbedaan topografi, hari hujan dan curah hujan berpengaruh terhadap kemunculan cacing nematoda gastrointestinal pada sapi dengan lingkungan dataran rendah lebih tinggi prevalensi dan derajat infestasi daripada dataran tinggi (P0,05). Sementara dari segi manajemen pemeliharaan terlihat sangat berisiko di dataran rendah daripada dataran tinggi (P0,01).

Advances in semen quality analysis technology are developing rapidly. Computer-based semen analysis technology provides a more objective assessment of spermatozoa motility by measuring various kinematic movements of spermatozoa cells. This study aimed to analyze differences in spermatozoa movement patterns using Computer-Assisted Semen Analysis (CASA) in various goat breeds. This study used frozen semen from four goat breeds: Boer, Ettawa crossbred (PE), Saanen, and Anglo-Nubian. Parameter observations were conducted on thawed frozen semen from two straw samples for each group, consisting of six replicates from each breed. The observed sperm kinetic movement characteristics were VAP, VCL, VSL, DAP, DCL, DSL, STR, LIN, WOB, ALH, and BCF. The results showed that sperm movements did not differ significantly (P0.05) in VAP, VCL, VSL, DAP, DCL, and WOB. There were significant differences in DSL, the highest in Saanen 21.993.01 m/second, the highest STR and LIN values in Boer 0.690.04% and 0.450.03%, the longest ALH Anglo Nubian 6.190.39 m, and the largest BCF Boer 25.561.87 Hz. This study concludes that differences in goat breeds affect the kinematic movement of spermatozoa as measured by CASA in the parameters of DSL, STR, LIN, ALH, and BCF.
