Effect of Superovulation on Piglet Production

Sixty gilts with average body weight of 107.80 + 5.10 kg were used in an experiment to study the use of PMSG and hCG as superovulation agent to increase piglet production. In this experiment 60 gilts were assigned into a completely randomized design with 4 treatments of superovulation with dose level 0, 600, 1200 and 1800 IU/gilt. Injections were conducted 3 days before estrus. During gestation, gilts were placed in single pigpen, and maintained to term. The parameters were birth weight, preweaning growth and mortality. The results showed that superovulation dose levels of 600 and 1200 IU/gilt increased the piglet birth weight, litter size, preweaning growth and piglet production at 90 days. It is concluded that superovulation with dose levels of 600 to 1200 IU can improve productivity. (Animal Production 8(1): 8-15 (2006

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Soybean is one of the legume crops and is the world's main source of protein and vegetable oil. Calcium is one of the essential elements needed by plants for growth and production. The purpose of this study was to determine the effect of calcium fertilizer on the growth and production of soybeans. This research was carried out from November 2020 to February 2021. The method in this study was a non-factorial randomized block design (RAK) with 4 types of calcium fertilizer treatments: 0 g/polybag (C0), 0.375 g/polybag (C1), 0.525 g/polybag (C2) and 0.865 g/polybag (C3). The results showed that calcium fertilizer had an effect on the number of pods, weight of pods, weight of filled pods, and weight of seeds. The calcium fertilizer treatment that gave the best results on the growth and production of soybeans was found in the C2 treatment at a dose of 0.525 g
