The study was conducted at Ardaita Agricultural Technical Vocational Education Training (ATVET) college dairy farm, to evaluate the reproductive performance of Holstein Friesian and its crosses with Boran cattle breeds. Data collected between 2000 and 2015 on reproductive traits (n=2632) were studied and analyzed using general linear model procedure. The overall estimated means for age at first...

As the reproductive age of women increases, women of reproductive age are exposed to more diseases and medications that are potentially related to adverse pregnancy outcomes. The approach to primary prevention of such outcomes is discussed. By minimizing the risks related to the diseases and the medications before conception, the best control of the medical condition and optimized pharmacothera...

The study was conducted to evaluate the effect of dietary dry fat inclusion on reproductive performance of Shami goats. Forty-five dry Shami goats (2 4 years of age, 64 kg body weight) were selected and divided randomly into 3 groups of 15 goats each in a completely randomized design. Treatments started 45 days before mating using one of three total mixed rations (TMR): 0, 3, or 5% of dry fat. ...

Dairy cattle breeding is one of the most important branches livestock production, which has been facing, for several decades, chronic problem declining reproductive performance. In 2005, number worldwide was about 1,370,000,000, while in 2015 that dropped below billion, and 2021 it shows a slight recovery as 1,000,970. This indicates importance applying different protocols order to increase cow...

the present study seeks to investigate users’ perception and evaluation of the function of designed environments and highlights a deeper understanding of man-environment relationship. the study tries to answer the question: “is there any relationship between the physical features of environment and users’ perception and evaluation of the environment and their spatial behaviors?” such investigat...

The recent decline in fertility is a serious problem in the dairy industry. To overcome this problem, we performed a genome-wide association study using 384 Holsteins and identified four loci associated with conception rates. Two of them contained gap junction-related genes: PKP2 and CTTNBP2NL. Further analysis confirmed that PKP2 increased connexin 43, a gap junction protein, whereas CTTNBP2NL...

evidence-based safer conception programs from high-resource countries. Furthermore, these implementation studies will identify the adaptable program components to ensure cost-effective and sustainable services in low-resource settings. From a reproductive justice perspective, HIV prevention programs should include accessible safer conception services for HIV-affected couples. Financial support ...

HIV-affected couples face unique challenges that require access to information and reproductive services to prevent HIV transmission to the uninfected partner and offspring while allowing couples to fulfil their reproductive goals. In regions of high HIV prevalence in sub-Saharan Africa, HIV-affected couples require multipurpose prevention technologies (MPTs) to enhance their reproductive healt...
