Abstract

This study was conducted to determine and identify the effect of litter size and piglet sex of on the gestation length of Landrace-Duroc crossbred pigs. Fifteen sows from the Manufarm farm in East Kupang district, Kupang regency, East Nusa Tenggara, Indonesia, were used in this study and were bred using artificial insemination (AI). Data were collected using a purposive sampling method based on certain criteria. Both primary and secondary data were utilized. Primary data were obtained through surveys, observations, and interviews, while secondary data were obtained from the farmers' data records. The research variables observed in this study included litter size, piglet sex, and gestation length. The data obtained were analyzed using Spearman's correlation test to examine the correlation between litter size and piglet sex with gestation length in Landrace-Duroc crossbred pigs. The results showed that the average litter size was 10.4 ± 0.986 piglets, consisting of 5.0 ± 1.852 males and 5.4 ± 1.882 females. The gestation length ranged from 111 to 114 days, with an average of 112 ± 0.926 days. The results of the Spearman correlation analysis showed that litter size was not significantly correlated with gestation length (p >0.05). Similarly, piglet sex showed no significant correlation with gestation length for both male (p >0.05) and female piglets (p= 0.254; p >0.05).

Abstract. Wuhan YOP, Haryanto A, Tjahajati I. 2020. Short Communication: Molecular characterization and blood hematology profile of dogs infected by Ehrlichia canis in Yogyakarta, Indonesia. Biodiversitas 21: 3242-3248. Ehrlichia canis is Gram-negative intracellular obligate bacteria that cause ehrlichiosis, a companion vector-borne disease is a potentially fatal disease that attacks dogs. The purpose of this study was to molecular characterize and determine the features of Ehrlichia-infected blood based on the amplification of the gltA gene in Ehrlichia infected dogs from Yogyakarta, Indonesia. Blood samples were collected from 51 dog patients from the Prof. Dr. Soeparwi Animal Hospital, animal clinics, and pet shops based on the anamnesis, clinical sign, and physical examination, followed by microscopic examination, routine hematology, PCR amplification, and DNA sequencing were carried out on the blood samples. Based on positive PCR amplification and blood hematology profile examination ehrlichiosis-positive in dogs showed that thrombocytopenia case was 82.3%, anemia was 70.5%, eosinopenia was 70.5%, neutropenia was 29.4%, monocytopenia was 23%, leukopenia was 17% and lymphopenia was 11.7%. Morulae of Ehrlichia sp.was not found in microscopic examination. Molecularly, detected of E. canis using the gltA gene showed that 34% of samples were positive results. Then 5 of positive Ehrlichia samples were DNA sequenced, they showed a high homology of 100% with Hat Yai isolates (KU765199.1). There was no genetic diversity between E. canis samples in Yogyakarta.
