Abstract
Forty buffaloes of post-partum anoestrus and repeat breeder were selected for on-farm trial of 90 days duration at tribal villages viz. Jinjari and Kharod in Panchmahal district. The buffaloes were selected on the basis of history as well as gynecological examination, the postpartum anoestrous (not showing symptoms for more than 100 days after calving) and repeat breeding (not conceiving following three inseminations) animals were randomly allotted to two dietary treatments i.e. T1 (Ionic mineral mixture) and T2 (Chelated mineral mixture comprising of Zn in chelate form added extra @ 25% to ionic), following Completely Randomized Design. The buffaloes in control group (T1) were supplemented ionic mineral mixture with feeding schedule followed by the farmers (concentrate + green roughage + dry roughage) and those in chelated mineral mixture group (T2) were reared on farm feeding schedule + compound concentrate mixture. The average DMI (kg/head), DCPI (g/head) and TDNI (kg/head) in T1 and T2 groups were 11.46 ± 0.14 and 11.53 ± 0.10; 592.80 ± 17.88 and 567.96 ±11.22 and 6.40 ± 0.06 and 6.43 ± 0.12, respectively in anoestrus buffaloes. Similarly, in repeat breeder buffaloes, the respective intakes in T1 and T2 groups were 11.41 ± 0.10 and 11.47 ± 0.09; 583.82 ± 16.76 and 582.41 ± 5.67 and 6.64 ± 0.08 and 6.60 ± 0.03. The DM1, DCPI and TDNI in anoestrus and repeat breeder buffaloes were found to be statistically similar and in confonnity to ICAR, (1988) standards. The average intakes of Ca, P and Cu were more than adequate in anoestrus and repeat breeder buffaloes. However, the Zn intake as the per cent of requirement was 66.27±2.37 and 65.58±2.13 in anoestrus buffaloes of ionic and chelated group, and the respective figures in repeat breeder buffaloes was 64.02±1.74 and 66.28±2.37%. The experimental buffaloes were supplemented with appropriate mineral mixture either in ionic or chelated form. The average blood glucose level (mg/dl) in ionic and chelated group of anoestrus (59.50±0.59 and 61.35±0.77) and repeat breeder (59.68±0.57 and 61.40±0.29) buffaloes. The treatment groups did not differ from each other. The period effect was also not significant. The ionic and chelated groups did not differ significantly in anoestrus buffaloes for levels (g/dl) of serum total protein (7.14±0.22 and 6.98±0.22), albumin (3.67±0.10 and 3.53±0.14) and globulin (3.48±0.15 and 3.45±0.09). The respective figures for repeat breeder buffaloes were 7.02±0.21 and 7.08±0.20, 3.56±0.12 and 3.58±0.11 and 3.46±0.09 and 3.51±0.09 (g/dl). However, the period effect was found significant (P<0.01) in all the variables in anoestrus and repeat breeder buffaloes except for level of globulin in repeat breeder buffaloes. Similarly, the ionic and chelated groups did not differ significantly in anoestrus buffaloes for levels (g/dl) of serum triglycerides (30.40±0.76 and 31.65±0.84), cholesterol (127.98±6.45 and 128.88±7.41), BUN (26.50±1.58 and 24.55±1.57) and Serum creatinine (1.94±0.07 and 1.54±0.03). The respective figures for repeat breeder buffaloes were 32.63±2.54 and 33.00±0.97, 122.00±7.20 and 116.48±5.46, 27.20±1.34 and 25.88±1.42 and 1.93±0.09 and 1.50±0.01 (mg/dl). However, the period effect was found significant (P<0.01) in all the variables in anoestrus and repeat breeder buffaloes' except for level of serum triglycerides in anoestrus buffaloes. In anoestrus buffaloes the ionic and chelated groups did not differ significantly for activity (U/L) of serum AKP (233.13±8.03 and 209.58±9.11), ALT (52.30±1.36 and 54.40±2.26) and AST (172.58±6.07 and 175.13±5.54). The respective figures for repeat breeder buffaloes were 218.83±5.09 and 208.10±9.91, 54.13±1.71 and 56.70±2.17 and 158.10±L73 and 162.45±2.09 (U/L). However, the period effect was found significant (P<0.01) with regard to activities of AKP and ALT both in anoestrus and repeat breeder buffaloes. The ionic and chelated groups did not differ significantly in anoestrus buffaloes with regard to levels (mg/dl) of serum calcium (8.38±0.61 and 8.64±0.63), Serum phosphorus (5.70±0.30 and 5.93±0.46) and serum magnesium (2.67±0.24 and 2.66±0.24). The respective figures for repeat breeder buffaloes were 8.67±0.58 and 8.76±0.58, 5.76±0.33 and 5.84±0.30 and 2.62±0.22 and 2.63±0.25 (mg/dl). However, the period effect was found significant (P<0.01). In both the groups of buffaloes, level of serum Calcium and phosphorus increased by 30th day of supplementation and stabilized thereafter. However, serum magnesium increased by 30th day and slightly declined thereafter. The levels (mmol/L) in anoestrus buffaloes did not differ significantly for serum sodium (142.13±2.83 and 143.85±1.11) and Serum potassium (8.69±0.37 and 8.48±0.38) in both the groups. The respective figures for repeat breeder buffaloes were 146.63±1.08 and 143.40±2.36 and 9.00±0.48 and 9.43±0.54 (mmol/L). The period effect was found significant (P<0.01) with regard to serum potassium level in anoestrus buffaloes. The ionic and chelated groups did not differ significantly in anoestrus buffaloes with regard to serum zinc level (ppm) which was 1.99±0.27 and 2.25±0.30, respectively. Similar was the trend in repeat breeder buffaloes and the respective values were 1.95±0.25 and 2.19±0.27. The period effect was found significant (P<0.01) and in both groups the level of serum Zn progressively increased up to 90th day. The average number of days required in ionic and chelated group, for correcting the condition of anoestrus was 63.00±5.81 and 54.33±6.10 and repeat breeding 68.80±5.28 and 51.57±7.26, respectively. Among the animals under study, 50% each of the anoestrus and repeat breeder buffaloes got successfully conceived due to ionic mineral supplementation. Whereas, due to chelate mineral supplementation respectively, 60 and 70% of anoestrus and repeat breeder buffaloes got successfully conceived. The average total cost (Rs.) including that of feed stuffs and mineral supplement for rearing anoestrus buffaloes worked out as 6637.91±579.34 in ionic group and 5303.40±692.97 in chelated group. In repeat breeder buffaloes the cost worked out as Rs. 6930.51±704.22 in ionic group and 5181.93±740.52 in chelated group, respectively. It is concluded that anestrous and repeat breeder buffaloes responded favorably to daily supplementation of 30 g appropriate mineral mixture in ionic/inorganic form. But chelated/ organic mineral mixture (comprising of Zn in chelate form added extra @ 25% to ionic) resulted in better response with 25 and 34% lesser cost of rearing in anestrous and repeat breeder buffaloes, respectively.
