| Abstract |
Data were collected from records of the Egyptian buffalo herd raised during the period from 1991-2000 at three state farms (namely NG, NK and MM) located in the northern part of Nile-Delta. The work aims to study causes of buffalo disposal as well as factors affecting percentages of disposal. Percentages of the different aspects of disposal were calculated in proportion to the total number of the detected disposal cases (2798 records).
The results indicated that annual average of buffalo disposal was 28.23% of the herd size, the major percent of culled animals (64.1 %) was achieved by selling animals (S) at different age categories. The remainder percent of disposal (35.9 %) was attributed to either animal risky slaughter (SL) or mortality (19 %) due to sudden death (D), abortion (A) or still birth (ST). The effects of production year and months of the year on aspects of animal disposal were highly significant (P < 0.01). The rate of S during winter months was found be the highest among the year. Percentages of S from each of the farms NK and NG were relatively greater than that from the farm MM (16.2%). Annual disposal of animals by slaughter (SL) ranged between 1-3.7%. Greater percentage of SL was observed in NK farm in. comparison with other farms.
Greater percent of M was enhanced when animals exposed to heat or cold stress in summer and winter. Cases. of sudden death (D) represented 9.04%. Months of September to February had the greatest percent of D which may refer to increased 'cold stress. Percentages of D in MM (3.54%) and NK (3.68%) farms were greater than that of NG (1.82%) farm. The greatest percentages of D were observed for the calves aging less than 6 months. The percentage of A represented 2.4% of the total number of disposal. The highest percent of A was noticed in months of June and July which may be attributed to the high ambient temperature during the summer months. The percentage of ST was 7.6% of the total disposal. Autumn months had the highest percent of ST.
The animals were subjected to descending percentages of disposal from 17.5% for calves less than 6 months of age to 9.3% for calves and
heifers approaching age at first conception. Considerable percent of disposal was noticed between 24-48 months of animal age due to intensive selling of females. The total animal losses were relatively diminished in NG farm when compared with other farms. In contrary, the farm NK attained the maximum losses or forfeited value due to higher percent of mortality in addition to severe pattern of culling animals.
It can be concluded that decision making in culling policy of buffalo raised in the state farm in addition to effective control of farm management and environmental conditions may positively affect the rate of animal disposal hence improving the economic efficiency of production.
