“…Te present study revealed that about 81.5% of the farmers get regular AI service which is in close agreement with the previous report of Ibrahim and Seid [19] who stated that 85% of small-scale farmers in Western Shoa Zone, Ethiopia, received regular AI service, but higher than the twofolds of prior studies by [20][21][22] who documented 34.2%, 27.7%, and 30.2% in Wolaita Sodo, Kaliti, and Debretabour, respectively. Tis disparity might be accounted by farmers' knowledge of estrus and their understanding of the value of crossbreeding.…”

Artificial insemination (AI) is among the most effective reproductive biotechnologies that afford widespread propagation of genes carried by superior males. A cross-sectional study followed by a simple random sampling technique was conducted from December 2021 to May 2022 to assess the constraints of artificial insemination (AI) provision in and around Kacha Bira district, Southern Ethiopia, using a structured questionnaire. A total of 200 respondents were surveyed accordingly. In this study, the education level of farmers revealed no statistically significant difference P > 0.05 with the identification of time of insemination. Conception failure (62.5%), unavailability of artificial insemination technicians (7.5%), dystocia (3.5%), and both conception failure and unavailability of artificial insemination technicians (4.5%) were found to be the major constraints of AI service in the study area according to dairy cattle owners’ response and revealed a statistically significant difference P < 0.05 with AI service. Although statistically significant P < 0.05 , differences in AI service interruptions during both regular working hours and weekends and holidays were also observed. Among total respondents, 20.5% of dairy cattle owners got AI service at right time, but 79.5% of them used it at the wrong time. Regarding inbreeding problems, 77.5% of dairy cattle owners responded that there was no inbreeding problem and the remaining 22.5% of farmers indicated presence of inbreeding problem of which 10.5% and 10% had a perception that local breeds had low milk production and low genetic improvement than exotic breeds, respectively. On the other hand, 11.5% of dairy cattle owners responded that local breeds have a similar level of disease resistance to that of exotic breeds (11%). 48.5% of dairy farmers reported that bellowing is the most frequent sign that they used to detect heat followed by vulval discharge (23%) and mounting on other cows (10%). Majority (78.5%) of the dairy cattle owners interviewed were found to be not satisfied with the artificial insemination services. In general, different AI technicians and cattle and dairy cattle keeper-related factors constrain the AI service and its result in survey site. Therefore, smallholder dairy cattle owners should be trained sufficiently about the AI service strategies, usage, and proper management of dairy farms and the technical constraints should be avoided in order to provide AI service sufficiently.

“…Comparison of these parameters between the two breeds reveals that the body size of Azikheli is smaller than that of Nili-Ravi, a breed that is well adapted to life in the plains. Owing to their low maintenance requirements (Ibrahim & Brannang, 2001), smaller animals are considered less susceptible to fodder shortages (Hall, 1998) and are able to move more easily and rapidly on mountain slopes (Ouma et al, 2004). As the Azikheli is native to mountain valleys with high seasonal fluctuations in the availability of feed resources, its smaller body size can be interpreted as an adaptive trait to fodder fluctuations, as well as to grazing in mountain terrain and transhumance.…”

This study aims to characterize Azikheli, an undocumented buffalo breed, in its home tract (Khwazakhela, Swat, Pakistan) under traditional farming conditions. For this purpose, 108 buffalo cows and 27 bulls were randomly selected. Mean, standard error, Student's t test and Chi-square test were used for various comparisons. The results show that the majority of animals have a brown coat colour. Cows have significantly higher heart girths, longer horns, longer necks and wider faces at the level of the eyes than bulls, whereas bulls have significantly longer bodies, longer ears, thicker horns, thicker necks and larger hooves than cows. Horns are flat laterally, directed backwards and then slightly upwards without twisting, leading to a sickle to semi-sickle appearance. Owing to its small body size and brown coat colour, the breed is well adapted to mountain slope grazing and thrives well away from swamps. Its adaptation to mountainous ecosystems warrants its in situ conservation.

“…Calvin interval is an important reproductive index, as it affects the total milk yield during lactation and the number of calves born from cows; thus, the dairy systems should aim at an ideal 12-13-month CI (Ibrahim and Seid, 2017). In addition to a reproductive problem and with direct consequences in the number of lactating cows, CI often reflects problems associated with management (Dono et al, 2013).…”

“…Thus, we observed that the second CI (CI23) decreased in relation to the first (CI12) for the evaluated genetic groups, except for group H (Table 2). The decrease in CI is directly related to the days open, which include anestrus and service periods of cows and should vary from 80 to 85 days to allow the production of one calf per year (Ibrahim and Seid, 2017).…”

“…Singh et al (2016) reported that reproductive efficiency varies not only between breeds but also among the animals within the same breed. However, these observed variations can also be explained by regional seasonal changes, such as calving season or other environmental factors (Boni et al, 2014), i.e., the reproductive efficiency of animals does not depend only on the genetic merit of the animals (genetic composition), but also on other factors such as nutrition, management, health, and the environment (Ibrahim and Seid, 2017).…”

Breeding and geneticsFull-length research article Breed and heterosis effects on reproduction and production traits of Girolando cows ABSTRACT -The objective of this study was to evaluate the breed and heterosis effects on reproductive traits, test-day milk yield, and 305-day milk yield in different lactations of crossbred Girolando cows. Data consisted of test-day milk yield records of first (118,831 records), second (63,227), and third lactation (44,512) and their relative productive (test-day milk yield, 305-day milk yield, and lactation length) and reproductive (age at first calving, calving interval, days open, and dry period) records of 35,582 Girolando cows from Brazil, collected from 1998 to 2014. The heterosis effect of the evaluated traits in Girolando cattle was estimated by MIXED procedure in SAS. Girolando cows showed a negative (favorable) and significant heterosis effect for reproductive traits. The dry periods between the first and second calving and between the second and third calving showed the greatest gains in heterosis (21.93 and 10.41%, respectively). All the evaluated productive traits showed a significant and similar heterosis effect between the three lactations. The use of crossbreeding strategies between the Holstein and Gyr breeds, instead of using the pure breed, is indeed a good alternative to increase the economic efficiency of the dairy activity in the different production systems in tropical environments.
