Abstract

The objective of this study was to determine the effect of sex and age of slaughter on the carcass characteristics of white Brahman crossbred cattle in feedlot Lampung, Indonesia. A total of 126 white brahman cattles consisting of 63 steers (21 PI0, 21 PI1, 21 PI2) and 63 bulls (21 PI0, 21 PI1, 21 PI2) were selected for this study. The slaughter was conducted using non stunning method using box mark 4. Data analysis was done using factorial completely randomized design and Duncan's continued test. The results showed that the slaughter age factor significantly (P <0.05) had a significant effect on slaughter weight, carcass weight, carcass percentage, meat weight, fat weight, fat percentage, bone weight, bone percentage, meat bone ratio (MBR), meat fat ratio (MFR) and rib eye area (REA). The interaction of sex and slaughtering age factors showed a significant effect (P <0.05) on slaughter weight, carcass weight, meat weight, meat percentage, bone percentage, and MBR. Sex and age of slaughtering had no significant effect (P> 0.05) on the thickness of the back fat of the white Brahman crossbred cattle. It can be concluded that the factors of sex and age have an effect on the carcass characteristics of the white Brahman crossbred cattle.Keywords: Carcass Characteristics, White Brahman Crossbred, Steer, Bull, Age

Abstract

Artificial insemination is one of the biotechnologies in livestock reproduction that allows the mating process of female livestock to be carried out without the presence of a male. AI involves a series of procedures that are designed in a planned and programmed manner, with the aim of improving the genetic quality of livestock in the future. AI technology is a solution to accelerate the increase in the beef cattle population. The opportunity for beef cattle farming in Seputih District, Surabaya, Central Lampung Regency has great potential to be developed because it can provide benefits for the community who raise livestock. From this, it is necessary to study the success rate of artificial insemination (AI) in Limousin cattle in Central Lampung Regency. This study was conducted in November 2023 in Srikaton Village (SK3), Seputih District, Surabaya, Central Lampung Regency. The variables observed included Respondent Characteristics, Service Per Conception (S/C), and Conception Rate (CR). From the results of the study, it can be concluded that Service per Conception (S/C) was recorded at 1.32. High S/C values ​​tend to cause longer birth intervals compared to livestock that have normal birth intervals of 12 months. In addition, the Conception Rate (CR) obtained in this study reached 75.3%, which is in accordance with the ideal standard (CR) of cattle ranging from 60-75%, where the higher the CR value, the better the fertility rate of the livestock. Keywords: IB Success, Service Per Conception (S/C), and Conception Rate (CR)
