“…The buffalo species is an important livestock resource in both developing and developed countries [ 1 , 2 ], as demonstrated by the worldwide increase in the population in the last decades [ 3 ]. Although it is used in many countries for draught power and meat production, in developed countries, milk production is the main reason for buffalo farming.…”

“…In order to guarantee optimal milk production and ensure economic farm profitability, particular attention should be paid to the optimization of reproductive efficiency [ 3 , 5 ]. In Italy, buffalo milk is entirely used for the production of mozzarella cheese, which, in the late 90s, received important recognition by being included in the list of national DOP (Protected Denomination of Origin) products, and it is marketed mainly during the spring–summer period.…”

The aim of this study was to evaluate the efficacy of a progesterone-based treatment on anoestrus in buffaloes. Primiparous acyclic buffaloes (n = 276), were divided into three classes according to their days in milk (DIM): from 50 to 90 (Class I; n = 86), from 91 to 150 (Class II; n = 102) and from 150 to 200 (Class III; n = 88). Animals were synchronized using P4 vaginal implants, followed by timed artificial insemination (TAI). They were then allowed to enter into a larger group of buffaloes for natural mating 15 days after AI was performed, and pregnancy status was monitored from then on at 15-day intervals. Finally, the temperature–humidity index (THI) was calculated. Statistical analysis was performed by ANOVA by means and both multiple and linear regression. The total pregnancy rate (PR) was 87.7%, with no differences among DIM classes (88.0, 92.4, and 80.0% in Classes I, II, and III, respectively). However, the PR at TAI tended to be higher (p = 0.07) in buffaloes in Class II. The follicle (FL) area in Class II buffaloes was larger (p < 0.01) than that of the other classes. No influence of the THI on the total PR was recorded. The pregnancy outcome at TAI was affected by the FL area (odds ratio = 2.237; p < 0.05) and body condition score (BCS) (odds ratio = 1.256; p < 0.05). In conclusion, treatment with vaginal P4 optimizes pregnancy rates in anoestrus buffaloes, particularly when the animals are in mid-lactation and show an optimal BCS. Furthermore, the THI does not seem to affect the efficiency of the progesterone treatment.
