Abstract

This study aimed to evaluate dry matter intake (DMI), crude protein intake (CPI), and metabolite status, including blood urea nitrogen (BUN), glucose, and total protein, in female fat-tail sheep fed a complete feed. The study was conducted from July to September 2022 at a farmer group managed by PT Juara Agroniaga in Kanor Village, Bojonegoro Regency, East Java, Indonesia. A total of 200 female fat-tail sheep aged 1–2.5 years with an average body weight of 27 ± 4.65 kg were reared in 10 group pens (20 animals per pen). Feed intake was recorded daily for six weeks, and blood samples were collected to determine BUN, glucose, and total protein. Data were analyzed descriptively. The results showed that DMI and CPI were 71.00 ± 5.88 and 6.83 ± 0.57 g/kg BW0.75, respectively. Metabolite status showed BUN of 25.15 ± 6.94 mg/dL, glucose of 83.83 ± 14.43 mg/dL, and total protein of 4.54 ± 2.58 g/dL. The complete feed was consumed at an acceptable level under farmer conditions, as reflected by the observed DMI. however, the high fiber content and relatively low crude protein level may have contributed to suboptimal metabolite profiles. In conclusion, the nutritional quality of the complete feed influenced nutrient intake and was reflected in the metabolite status of female fat-tail sheep

Abstract

Thin-tail sheep is a local genetic resource widely raised by farmers and requires conservation through appropriate breeding programs. This study aimed to characterize quantitative and qualitative traits of thin-tail ewes reared at PT Juara Farm, Bojonegoro. A total of 66 ewes aged 1–4 years were observed, with quantitative traits including body weight, body length, body height, and chest girth, and qualitative traits focusing on tail shape. Data were analyzed descriptively. The results showed that all body measurements increased with age, with body weight ranging from 23.08 ± 3.83 kg in 1 – <2 years to 29.25 ± 3.79 kg in 3–4 years. Similar increasing trends were observed for body length, body height, and chest girth. Three tail shapes were identified: triangular (48.48%), straight (42.42%), and sigmoid (9.10%). The coefficient of variation indicated that body weight had higher variability compared to other traits. In conclusion, thin-tail ewes exhibit age-related increases in body size with moderate phenotypic variability, providing baseline information for breeding and conservation programs.

Abstract

Reproductive recording is essential for effective rabbit breeding management, yet manual systems often hinder breeding stock selection at the smallholder level. This study developed a rabbit livestock recording website using The Five Planes framework and evaluated its usability under ISO 9241-11:2018 across effectiveness (success rate and error rate), efficiency (task completion time), and satisfaction (System Usability Scale/SUS). Testing was conducted in two iterative phases involving animal science students and active rabbit farmers as respondents. Phase I (5 respondents) yielded a success rate of 86.25%, an error rate of 11%, an efficiency of 53.05 seconds per task, and a SUS score of 63.50 (Marginal High). Following interface improvements, Phase II (20 respondents) recorded a success rate of 74.38%, an error rate of 12%, an efficiency of 66.91 seconds per task, and a SUS score of 66.13 (Marginal High). This decline is primarily attributable to the inclusion of farmer respondents with more heterogeneous digital literacy in Phase II, rather than a deterioration in system design. These findings indicate that while The Five Planes framework produced a functionally robust recording website, further refinement is needed to improve usability for users with lower digital literacy before broader implementation in smallholder rabbit farming.
