AbstractThe current study was conducted on 907 adult buffalo cows, 60 cows suffering from anoestrus located in buffalo breeding farm in Nineveh province during the period from September 2002 to March 2003. The aim of this study was identify the incidence of anoestrus in adults Iraqi buffaloes in Nineveh province. Some biochemical changes in anoestrus buffalo cows were studied including calcium, inorganic phosphorus, total protein, glucose, and cholesterol in blood serum. Different hormonal therapy with supportive treatment were used. Animals included in this study 28 adult buffalo cows suffering from inactive ovaries and divided in to three treated subgroups with control group, each group contain 7 adult buffalo cows, and 32 adult buffalo cows suffering from persistent corpus luteum which divided in to three treated subgroups. with control group, each group contain 8 adult buffalo cows the results of this study show that total incidence of anoestrus in adult Iraqi buffalo cows in Nineveh province was 6.6% and 3.1% due to inactive ovaries and 3.5% due to persistent corpus luteum.
The biochemical Analysis showed blood calcium level increase significantly in (P<0.05) and total protein level decrease significantly in (P<0.05) in adult Iraqi buffalo cows suffering from inactive ovaries while blood calcium level increase significantly in (P<0.05) and cholesterol level decrease significantly in (P<0.05) in adult Iraqi buffalo cows suffering from persistent corpus luteum.
Treatment regime using GnRH with vitamin AD3E and phosphorus salt in adult Iraqi buffalo cows suffering from inactive ovaries showed high response on estrus sign (85.71%) and conception rate (71.5%) followed the treatment of progesterone alone and then GnRH alone respectively. While treatment regime using PGF2 a alone of adult Iraqi buffalo cows suffering from persistent corpus luteum showed high response on observed Estrus (87.5%) and conception rate (87.5%) followed by PGF2 a plus GnRH in three day interval then PGF2 a with Estradiol benzoate respectively. It was concluded that from this study the hormonal therapy or with supportive treatment could be successfully used in anoestrus buffaloes.
