| Abstract | In the Malwa region of Madhya Pradesh reproductive failure (anoestrus) is a major problem in buffaloes under field conditions due to under feeding and nonavailability of balanced ration. To find out the nutritional causes behind anoestrus, thirty anoestrus buffaloes 10 heifers (average body wt. 262.80+- 22.51 kg) + 20 buffaloes (average body wt. 461 +- 10.83 kg, milk yield 7.62 +- 0.48 litre/h/d) that had normal genitalia were selected randomly from ten villages of Indore district. Average daily feed intake of each animal was recorded and proximate principles, major (Ca and P) and trace elements (Fe, Zn, Mn, Cu and Co) in available feedstuffs were determined to find out nutrient availability. Deficiency of various nutrients was calculated by comparing with the standard requirements of the animals. A strategic nutrient supplement containing defi cient nutrients was formulated on the basis of nutrient deficiency observed in rations of buffaloes of Indore district and a supplementation study was carried out in the same thirty affected anoestrus buffaloes by dividing them into two groups of 15 (five heifers + 10 buffaloes) in each. One of them served as control (un-supplemented), while the other was supplemented with the strategic nutrient supplement (treatment). This supplementation study was continued for a period of two months, during which each individual animal was regularly examined for onset of estrus and artifi cially inseminated. After two months of the last artificial insemination, pregnancy diagnosis of each animal was carried out perrectally to find out the conception status. Onset of estrous (12 vs. 4) and conception rate (10 vs. 3) were higher in the animals of supplemented group and an additional advantage in the form of improvement (P LT 0.05) in the body weight of heifers of the treated group was also observed. On the basis of above findings it may be concluded that strategic nutrient supplementation not only improved the reproductive performance of the anestrous buffalo heifers and lactating buffaloes, but it also improved the growth performance of the heifers. |
