Application of Linear Body Measurement for Predicting Body Weight of Swamp Buffalo

Abstract

The objective of this research was to predict swamp buffalo weight using simple linier body measurement. The height of wither (TB), height of hip (TP), heart girth (LiD), width of chest (LD), dept of chest (DD), width of hip (LP), thurl length (PK), width of rump (LK), body length (PB) were measured in centimeters using measuring rib, one meter ruler, and measuring stick, whereas body weight was determined in kilograms using two tons weighing scale. Linier body measurement ratio between male and female swamp buffaloes was analyzed using t-test analysis. The relationship between linier measurement variables were analyzed using correlation analyisis. Body weight estimator was estimated using best subset regression, linier regression and multiple linier regression analysis. Result of T-test analysis showed that linier body measurement between male and female buffaloes have significant difference in hearth girth, height of hip and body length. Result of coefficient analysis showed that heart girth and height of hip have a highly correlation with body weight of male and female swamp buffalo. Estimation of swamp buffalo body weight could be estimated through multiple regression with heart girth and height of hip variables. It could be concluded that weight of swamp buffalo can be estimated using multiple linier regression formula, BB = 3.6435LiD + 0.1208TP-265.43 for male swamp buffalo and BB = 4.1783LiD-0.3086TP-305,19 for female swamp buffalo.

Phenotypic diversity characterization of Kalang and Thale Noi Buffalo (Bubalus bubalis) in Indonesia and Thailand: Perspectives for the buffalo breeding development

“…The average body length (129.62±7.30 cm) was lower compared to water buffaloes from Istanbul, Turkey (146.1±8.82 cm) (Kocaman et al 2017) but higher than reports from Nili-Ravi buffaloes from Okara, Pakistan (129.90±19.2 cm) (Tariq et al 2013). The average heart girth (181.17±6.59 cm) was lower compared to Murrah buffaloes from Hisar, India (226.27±4.78 cm) (Dhillod et al 2017) but agreed with swamp buffaloes from Cirebon, Indonesia (180.20±13.40 cm) (Galib et al 2017). The average shoulder width (43.13±2.64 cm) was similar to swamp buffaloes from Sylhet, Bangladesh (44.78±3.17) (Rahman et al 2015) but lower than local Egyptian buffalo bulls (47.16±3.30) (Genedy et al 2019) and higher (40.85±3.70 cm) compared to swamp buffaloes from Cirebon, Indonesia (Galib et al 2017).…”

The average chest depth (73.27±3.78 cm) was higher than the average chest depth of the male Murrah and swamp buffaloes (63.50±0.70 cm and 64.25±2.87 cm) in Tapanuli Utara, Indonesia (Gerli et al 2012) but lower than Murrah buffaloes from Hisar, India (76.23±1.27 cm) (Dhillod et al 2017).…”

“…However, the average rump height observed in the present study was lower compared to water buffaloes from Istanbul, Turkey (136.22±4.17 cm) (Kocaman et al 2017). The average rump width (45.17±3.14 cm) and rump length (33.04±3.00 cm) was higher than Murrah crossbred buffaloes in Brazil (39.99±5.62 cm and 25.38±4.23 cm) (de Melo et al 2018), swamp buffaloes from Cirebon, Indonesia (38.97±2.40 cm and 28.07±3.14 cm) (Galib et al 2017), and Italian Mediterranean buffaloes (40.77±2.35 cm and 27.41±6.50 cm) (Allegrini et al 2007), but lower than Azikheli Buffaloes in Swat valley, Pakistan (49.52±2.30 cm and 40.51±4.01 cm) (Khan et al 2013), and water buffaloes from Istanbul, Turkey (53.69±3.32 cm and 38.82±2.51 cm) (Kocaman et al 2017). For the average body weight (411.23±25.01 kg), the results of the present study agreed with Sambalpuri buffaloes of India (411.47±5.34 kg) (Sahu et al 2017), and swamp buffaloes from Cirebon, Indonesia (409.30±5.10 kg) (Galib et al 2017) but were higher than Nili-Ravi buffaloes from Okara, Pakistan (359.30±160.9 kg) (Tariq et al 2013) and lower than Murrah female buffaloes in North Sumatera, Indonesia (446.05±45.06 kg) (Djaja 2013), male Murrah and swamp buffaloes in Tapanuli Utara, Indonesia (474.20±73.06 kg) (Gerli et al 2012), and swamp buffaloes in Trishal, Bangladesh (458.70±49.94) (Siddiquee et al 2010).…”

“…The morphometric/body size was measured by a measuring stick (Modified Amano et al 1981) (Figure 2). The body weight (BW) estimation was calculated by the following formula, based on heart girth (HG) and rump height (RH) (Galib et al 2017): a) BW (male) = 3.6435 (HG) + 0.1208 (RH) -265.43, b) BW (female) = 4.1783 (HG) -0.3086 (RH) -305.19. Qualitative variable; (i) body appearance, three classes; small (<300 kg), medium (300-400 kg), and large (>400 kg) was based on body weight classification (Sahu et al 2017), (ii) skin color, (iii) coat color, (iv) horns pattern, was based on buffalo horns patterns classification (Stepanus 2008), (v) back-line, (vi) chevron, (vii) hair whorls on the head, (viii) hair whorls on the back, (ix) hair whorls on the rump, and, (x) foot color, were recorded.…”
