“…bulls therefore should be grown out early and well, avoiding, as far as possible damage to the testicular tissue from any cause. The age at which puberty begins depends on many factors, but size for the breed seems to be the main controlling factor (Korejo et al, 2019).…”

The Kundhi buffalo, a unique and robust breed of water buffalo (Bubalus bubalis), is native to the Sindh province in Pakistan. This breed is well-adapted to the local environment and known for its excellent milk production, meat quality, and draught power. There is a growing need to develop strategies that focus on the sustainable conservation and genetic improvement of this breed to preserve its valuable traits for future generations. Twelve young bull calves belonging to elite Kundhi buffaloes (observed phenotypically) were obtained from progressive farmers based on their parent's performance records. The bull calves, aged approximately 10-15 months, were initially weighed (rages from 150 to 200 kg) and randomly divided into three groups, namely C, S, and M, each group were comprising 04 animals. Group C was designated as the control group and fed basal diet only, while calves belonging to Group S were given a dietary supplement of Selenium Yeast Sel-Plex®, with a dosage of 0.3mg/kg dry matter and Group M was treated with Moringa olifera leaves (dried) at the rate of 100g/ animal. This experiment was conducted for 12 weeks. The results of present study indicated that significantly (P<0.05) higher monthly body weight gains (14.05 kg/month) were recorded in Kundhi buffalo bull calves of S followed by the M (11.67 kg/month) in comparison to the C group (9.75kg/month) of the animals. The positive coefficient of correlation was seen between age and body weight in all tested subjects. In terms of the body conformation; the monthly developmental gains of the heart girth, body length, and height were observed significantly (P< 0.05) higher (11.2, 8.89 and 8.94 cm) in S, followed by M (8.23, 4.89 and 6.39 cm) in comparison to the control bull calves (4.74, 3.58 and 3.27 cm), respectively. High levels of the testosterone (0.481 ng/ml) were determined in the bull calves of S, followed by M (0.33 ng/ml) in comparison to C (0.208 ng/ml) group. The monthly gains of the scrotal circumference were recorded significantly (P<0.05) higher (1.65 cm) in the S, than to M (1.21 cm) and that of control (0.40 cm) group calves

Abstract. The body size and ultrasound carcass traits are related to the growth and muscling of animals. These characters promise future improvement through genetic selection in animal breeding. In breeding programs, knowing the (co)variance components serves to reveal the performance differences among animals and detection of suitable traits for selection. The research was carried out with 313 Anatolian buffalo calves born in 2019 at 36 farm operations. The least-square means for body weight (BW), wither height (WH), rump height (RH), body length (BL), chest width (CW), hip width (HW), chest circumference (CC), cannon-bone circumference (CBC), longissimus muscle area (LMA), longissimus muscle depth (LMD), and subcutaneous fat thickness (SFT) in yearling calves were 175.41 ± 2.06 kg, 108.35 ± 0.34, 111.85 ± 0.37, 103.74 ± 0.41, 33.93 ± 0.23, 30.56 ± 0.23, 135.18 ± 0.60, 15.69 ± 0.08 cm, 19.36 ± 0.45 cm2, 3.086 ± 0.028, and 0.655 ± 0.006 cm, respectively. The direct heritabilities for BW, WH, RH, BL, CW, HW, CC, CBC, LMA, LMD, and SFT were 0.334 ± 0.032, 0.483 ± 0.044, 0.473 ± 0.043, 0.441 ± 0.041, 0.364 ± 0.034, 0.432 ± 0.040, 0.435 ± 0.040, 0.226 ± 0.021, 0.0001 ± 0.000, 0.300 ± 0.026, and 0.539 ± 0.046, respectively. The genetic and phenotypic correlations predicted in this study ranged from 0.02 to 0.90. All the genetic and phenotypic correlations among body size and ultrasound carcass traits were significant (P<0.01), except for the genetic correlation between CW and HW. Some polymorphisms in PLAG1, NCAPG, LCORL, and HMGA2 genes were analyzed. Two single-nucleotide polymorphisms (SNPs) for PLAG1 and NCAPG genes were found to be monomorphic in this buffalo population. Meanwhile, the effects of two SNPs in the LCORL and HMGA2 genes were not significant but showed some tendencies in the aspects of least-square means. The results of the study indicated that the Anatolian buffaloes have the potential to improve in growth and muscling characteristics.

This study was aimed to decipher the inter-relationship peripheral hormones [Insulin-like growth hormone (IGF-1), testosterone and growth hormone] with body weight, body condition score and scrotal circumfermnce across age-groups in male buffalo. Male buffalo (n=20) of different age groups viz. Group 1 (0 to 8 months), 2 (9 to 16 months), 3 (17 to 24 months) and 4 (25 to 32 months) were selected and Blood was collected along with body weight, body condition score and scrotal circumference. Significant difference (P<0.05) in the body weight, body condition core and scrotal circumference was observed between the groups. Peripheral IGF-1 level increased with age, highest in Group 4 (202.4±9.36 ng/ml). Similarly, testosterone was different between Group 1, 2 and 4, highest in Group 4 (1.73±0.02 ng/ml). Growth hormone, differed (P<0.05) between Group 1 (3.65±0.50 ng/ml), Group 3 (3.65±0.50 ng/ml) and Group 4 (8.56±1.96 ng/ml). Postive correlation (P<0.05) between various parameters (body weight, body condition score and scrotal circumference, testosterone and growth hormone) was observed. In conclusion, this study reports the age-related variations and inter-relationships of peripheral hormones with body weight, body condition score and scrotal circumference in male buffalo.
