“…Live weight is a critical factor in determining potential milk production and traits of livestock, especially those with economic values (Khandoker et al 2018;Moroz and Samorukov 2020). In additionbody size and live weight are two major factors that can be used to evaluate goat growth performance and are critical indicators for improving goat production (Kari et al 2019;Fonseca et al 2021).…”

Live weight is one of the parameters for evaluating milk and meat production of livestock. Live weight is an important indicator for improving production traits. The present study was conducted to measure growth performances based on two factors; sex differences and litter size and observation of survival between these factors during the sample period. Data from 22 Saanen kid were recorded for 6 weeks. Results showed that male kid had higher live weight than female kid (P0.05), with a difference of 3.3% in the percentage of live weight gained over 6 weeks of sampling. This resulted in a body gain of 0.68 kg/day for male kid and 0.48 kg/day for female kid. The current study also showed that twin kid had a higher average live weight than single kid (P0.05). The average size of single-born Saanen kid was not significantly different from twin-born Saanen goat kid (P0.05). Twin-born Saanen kid gained 9.9% more live weight in 6 weeks than singleton- born. Survival was 86.4%, with all deaths attributable to singleton-born kid. In this study, preweaning kid survival was not affected by sex or litter size, but was affected by maternal age. Other factors such as pellet deficiency should be considered as they affect the overall production of the animals. The data collected in this study could potentially lead to more accurate evaluation of breeding value, and improvements in feeding and management.

Changes in body mass are a key indicator of health and disease in humans and model organisms. Animal body mass is routinely monitored in husbandry and preclinical studies. In rodent studies, the current best method requires manually weighing the animal on a balance which has at least two consequences. First, direct handling of the animal induces stress and can have confounding effects on studies. Second, the acquired mass is static and not amenable to continuous assessment, and rapid mass changes can be missed. A noninvasive and continuous method of monitoring animal mass would have utility in multiple areas of biomedical research. Here, we test the feasibility of determining mouse body mass using video data. We combine computer vision methods with statistical modeling to demonstrate the feasibility of our approach. Our methods determine mouse mass with 4.8\% error across highly genetically diverse mouse strains, with varied coat colors and mass. This error is low enough to replace manual weighing with image-based assessment in most mouse studies. We conclude that visual determination of rodent mass using video enables noninvasive and continuous monitoring and can improve animal welfare and preclinical studies.

The Indonesian government designated the Sakub sheep as a local breed in 2022, and it is mainly cultivated in Brebes Regency, Central Java. This study investigates the growth patterns and morphometric characteristics of Sakub sheep as a local breed in the Brebes Regency. The data were collected from 195 healthy and non-pregnant female Sakub sheep reared by smallholder farmers. The sheep were categorized into eight age groups, and various morphometric measurements were performed, followed by descriptive data analysis. The results showed that body weight (BW), chest width (CW), and chest depth (CD) experienced optimal growth until 36–48 months with average body weight and size of 47.34 kg, 21.76 cm, and 35.35 cm, respectively. The body size of heart girth (HG), body length (BL), and hip height (HH) grew optimally for 7–12 months at 80.40, 64.73, and 65.08 cm, respectively. Wither height (WH) and hip-width (HW) growth were optimal for 12–24 months at 67.27 and 15.77 cm, respectively, gradually developing into maturity. In conclusion, this study showed the rapid growth of female Sakub sheep, indicating that body weight and size (CW and CD) generally grew to maturity. In contrast, the growth pattern of body size related to BL, WH, HH, and HW showed rapid growth from birth to puberty, followed by a decline in development rate at post-puberty. The body weight of female Sakub sheep has a positive and significant correlation to all linear body sizes, but in different age categories, the correlation weakens with age.
