Agroecological distribution and population
The present investigation revealed that the breeding tract of local goats (Surguji) is located in the Northern hills of Chhattisgarh state. The highest population density was observed in Surajpur, Surguja and Balrampur districts (Fig 1). The northern hills are part of the Maikal range within the Satpura mountains. These hills spread over 28.47 lakh hectares, accounting for 21% of the state’s total geographical area. The investigated area is home to tribal communities such as Gonds, Korwas, Oraon, Kanwar and Pando, where goats are socio-economic and cultural heritage and primarily reared for meat production. The Satpuda hill ranges cover a significant part of the region, with approximately 58% of the area in the three districts covered by forests. The majority of this population consists of nondescript goats, with only a small percentage representing improved breeds. Balrampur district (0.34 million) had the largest goat population, followed by Surguja district (0.28 million) and Surajpur (0.25 million), collectively totalling approximately 0.87 million goats in the studied area.
Management practices
The studied population was mainly maintained in an extensive rearing system, with farmers building sheds for goats near or within their dwellings to provide shelter at night. Few farmers house all their animals together in one shed; they use locally available materials such as bamboo, wood and earthen tiles for the construction of their shed. Many kachcha houses were found in the studied area. Most shelters had elevated wooden or bamboo flooring. Extensive rearing was common among local goat farmers, with goats grazing for an average of 6-8 hours daily in natural grasslands, forests and hilly terrains. Natural vegetation was the only source of their nutrition and they often supplemented with concentrates like wheat and maize. All farmers provide water to their goats during grazing, including water washed out of rice, pulses and rice starch, Due to limited awareness and lower literacy among goat farmers, they generally do not maintain breeding records. Major health issues include diarrhoea, pneumonia, parasitic infestation and bloat. Vaccination and treatment coverage were better in the surveyed area due to the presence of a private artificial insemination worker and an assistant veterinary field officer.
Physical appearance
Surguji goats were strongly built, medium-sized, compact, primarily light brown coloured indigenous goat, often with a white belly and a distinct black dorsal line along their back side (Fig 2c). It may also have variations such as white or black colouration, (Fig 2b). It features a black margin on the apical half of the ear and a black ring around the neck, more prominent in adult males (Fig 2a). Surguji goats had horizontal, erect ears and a straight head profile (Fig 2b). They possess small, hairy udders and funnel-shaped teats with pointed ends. These hardy goats were well adapted for grazing and browsing across diverse herds and forages in the hilly terrains of northern Chhattisgarh.
Morphometric traits
The mean, standard error and number of observations for body weights in male and female goats at different ages from birth to over 2 years are summarized in Table 1. Male kids weighed 2.64±0.02 kg at birth, 9.79±0.44 kg at 3 months, 13.64±0.09 kg at 6 months, 21.92±0.10 kg at 1 year and 33.10±0.54 kg above 2 years, whereas females weighed 2.13±0.02 kg at birth, 7.85±0.05 kg at 3 months, 11.30±0.10 kg at 6 months, 14.11±0.08 kg at 1 year, 17.10±0.08 kg at 1
st kidding and 28.60±0.09 kg above 2 years. The study reveals that male goats were significantly heavier than females across all age groups. The body weight of an animal depends on various factors like breed, sex, birth weight, birth type (singles, twins), feeding, nutrition and climatic conditions. Kids born as singletons tend to have a higher body weight than twins or triplets. The mean birth and body weights of Surguji goats were lower than those of local goats from the Central plain region of Chhattisgarh, Bundelkhandi and Bhakharwal goats
(Bhuarya et al., 2014; Ahmad et al., 2020; Sharma et al., 2024), but higher than Rohilkhandi
(Sharma et al., 2020), Pugari
(Alam et al., 2023), Narayanpatna, Malkangiri and Ganjam
(Majumder et al., 2023) and Indigenous goats from the Vindhya region (
Kumar et al., 2024). The values for linear measurements such as body length, height at withers, chest girth, ear length, horn length and tail length for males were 63.82±0.99, 66.55±0.51, 75.87±0.52, 15.59±0.18, 13.92±0.24 and 11.36±0.23 cm, respectively and slightly lower corresponding values were recorded for females: 61.50±0.21, 63.61±0.19, 72.44±0.27, 15.66±0.20, 13.13±0.24 and 11.36±0.18 cm. Generally, males tend to be heavier and taller than females due to physiological and hormonal effects. The results were further supported by the finding that the district-wise assessment exhibited a non-significant influence, whereas sex-wise analysis showed a highly significant effect, as females of the same age had linear measurements than male goats. The mean body length showed minimal difference between male and female goats, although height at wither and heart girth were higher in males (Table 1). Other measurements, like ear, horn and tail length, were comparable. Statistical analysis of variance revealed a highly significant influence of sex and a non-significant effect of district on various morphometric measurements (Table 1).
Tantia et al. (2018);
Alam et al., (2023); Sharma et al., (2024) and
Kumar et al., (2024) reported higher values for body measurements across all age groups in Bidri, Pugari, Bhakharwal and local goats of Vindhya region.
Majumder et al., (2023) reported higher mean estimates for body length (BL), height at wither (HAW) and lower estimates for heart girth (HG) in Narayanpatna and Malkangiri goats. Conversely, Kashmiri, Kotdhar and Raighar goats showed lower estimates for all measurements
(Rather et al., 2025; Dinesh et al., 2024; Venkatesh et al., 2025).
Reproduction traits
The production performance for Surguji goats is presented in Table 2 and Fig 3. The estimated age at first mating in males was 208.14±2.69 days, indicating early maturity. The ages at first oestrous, first mating and first kidding were 208.15±1.21, 253.87±1.53 and 445.66±3.60 days, respectively (Fig 3), reflecting early maturity within 12-15 months, which is typical for indigenous goats in India. The study reveals that male and female Surguji goats reach first mating age around 7 and 8.5 months, respectively. This indicates these goats were good breeders and attained early sexual maturity, which is a desirable trait for meat-type goats. Higher estimates for age at first mating have been reported in Malabar, Jamunapari, Palamu and localgoats goats of Vindhya region
(Verma et al., 2009; Hassan et al., 2010; Sharma et al., 2024; Kumar et al., 2024). In contrast,
Bhuarya et al. (2014) in local goats of Chhattisgarh plains and Sunder
et al. (2018) in Andaman local goats reported lower estimates than the current findings. Surguji goats exhibit first heat symptoms and age at 1
st mating were within a range of 175-270 days and 210-310 days and typically give birth to their first kid at around 15 months, reflecting their early puberty and sexual maturity, then many other goat breeds but later than local goats from Central plain region of Chhattisgarh (Bhuarya
et al., 2014) and Andaman local goats
(Sunder et al., 2018). This aligns closely with the findings of Kumar
et al. (2024), who reported similar ages at first mating in indigenous goats from the Vindhya region. In contrast, goats from Assam hill, Narayanpatna, Malkangiri and Zokel breeds show a higher age at first kidding
(Das et al., 2021; Majumder et al., 2023; Lalhruaipuii et al., 2025).
Other reproductive parameters included a heat period averaging 38.32±0.02 hours, a service period of 126.87±5.48 days and a kidding interval of 276.28±0.15 days (Table 2). The service period and kidding interval were longer in indigenous goats
(Kumar et al., 2024) but shorter in Zokel goats
(Lalhruaipuii et al., 2025). The majority of Surguji goats gave birth to a single kid, but twinning and triplet births were also observed, indicating their potential for prolificacy. Twin and triplet births had been reported in Palamu and Rohilkhandi goats
(Singh et al., 2009; Sharma et al., 2020), while triplets were common alongside twins in Black Bengal goats
(Kumari et al., 2015). Statistical analysis was found to be non-significant, indicating that the studied goat population was almost similar across the districts for respective parameters. On average, these goats produced 7 to 10 kids over their reproductive lives, with a litter size of 1.49.
Production performance of surguji goats
The average lactation milk yield was 17.04±2.15 kg, with a daily yield of 252.72±3.99 ml over an average lactation period of 95.37±0.37 days. The average fat percentage and solids-not-fat (SNF) percentage were 4.02±0.05% and 8.92±0.06%, respectively (Table 3). The average daily milk production of Surguji goat was higher than Palamu, Indigenous goats of Vindhya region and Zokel goats
(Sharma et al., 2020; Kumar et al., 2024; Lalhruaipuii et al., 2025), whereas the total milk production of Surguji goats is lower than local goats from the Central plain region of Chhattisgarh
(Bhuarya et al., 2014), Palamu goats
(Sharma et al., 2020), which might be due to shorter lactation length (112 days). The longer lactation length and higher fat and SNF percentages were documented in Zokel goats
(Lalhruaipuii et al., 2025). In contrast, shorter lactation lengths were observed in Black Bengal and Palamu goats
(Sharma et al., 2020).
Carcase characteristics of Surguji goats
The carcass characteristics are detailed in Table 4. Surguji goats from northern hills are primarily raised for meat. The average age at slaughter was 10.34±0.65 months, with a slaughter weight of 18.30±0.64 kg, which was lower than Changthangi goats
(Ganai et al., 2011). The mean carcass weight was 9.49±0.35 kg and the dressing percentage was 50.92±0.31%, which was comparable to Palamu goats
(Singh et al., 2009) and higher than local goats of Vindhya region
(Kumar et al., 2024). Despite their relatively smaller body size, Surguji goats exhibit favourable meat production characteristics.
