“…The head index measurement was used to determine the head conformation of an animal, where it can be used to estimate the physiological feeding ability of livestock. This can also be used as a parameter in determining their appropriate feeding management and to estimate the closeness of the family relationship, where each animal has a different head conformation (Salgado et al, 2021).…”

Bali pig is an important livestock for meeting the meat needs of the community, especially in the Province of Bali, Indonesia. The characteristics of this animal include a slightly rough black fur, a long snout, curved back, and their stomach does not touch the ground when standing. This study aims to determine the morphometric characteristics and head index of Bali pigs using a Principal Component Analysis (PCA) approach to easily identify the phenotypic characteristics. The samples include 50 Bali pigs that are intensively reared in Musi Village, Gerogak District, Buleleng Regency, Bali Province, Indonesia. The measurement data were analyzed using PCA to reduce and interpret the measured variables. The results showed that the average hip height and width, rump length, body length, shoulder height, chest width and depth, head width and length were 55.68cm, 17.53cm, 10.62cm, 67.40cm, 54.92cm, 17.81cm, 41.24cm, 10.63cm, and 26.26cm, respectively. Furthermore, the result of measuring the index of the female and male heads was 40.76% and 39.41%. The results showed that Principal Component 1 (KU1) and 2 (KU2) had a variance of 5.834 and 1.834, respectively, while the percentage of variance was 58.338% and 18.340%, with a total value of 76.678%. The hip width, shoulder height, and chest width were significantly different (p<0.05) between male and female Bali pigs. In addition, the main characteristics of size for this specie include hip height, rump length, body length, shoulder height, chest width, and head width and length, while that of the shape include chest and hip-width

“…The ileal brake is a signal inhibiting feed intake, and it is stimulated by the presence of nutrients in the ileum [56]. However, Salgado et al (2021) report moderate correlations indicating an important variation in feeding behaviour that cannot be solely explained by in-between meal intervals or meal size [57].…”

Nutritional values of ingredients have been and still are the subject of many studies to reduce security margins of nutrients when formulating diets to reduce feed cost. In most studies, pigs are fed a limited amount of feed in a limited number of meals that do not represent how pigs are fed in commercial farm conditions. With free access to feed, pigs follow their intrinsic feeding behaviour. Feed intake is regulated by satiety and satiation signals. Reducing the feed intake level or feeding frequency can affect digestibility and transit time and induce metabolic changes. To reduce feed costs, alternative ingredients that are frequently rich in dietary fibre are added to diets. Fibre acts on the digestion process and transit time by decreasing energy density and causing viscosity. Various analyses of fibre can be realised, and the measured fibre fraction can vary. Exogenous enzymes can be added to counteract the effect of fibre, but digestive tract conditions, influenced by meal size and frequency, can affect the efficiency of supplemented enzymes. In conclusion, the frequency and size of the meals can affect the digestibility of nutrients by modulating gastrointestinal tract conditions (pH and transit time), metabolites (glucose and short-chain fatty acids) and hormones (glucagon-like peptide 1 and peptide tyrosine tyrosine).

“…Understanding patterns of feeding behavior can be useful for pig management (Brown-Brandl et al, 2013), breeding (Ding et al, 2018) and research (Brown-Brandl et al, 2018;Salgado et al, 2021). In pig farming, animals are typically housed in groups and animals often have to compete for access to feeder space (Georgsson and Svendsen, 2002).…”
