“…The results of the current study revealed poor reproductive performance of the selected dairy cows based on the standard values for fertility traits (McDowell, 1985;Hussain & Daneil, 1991;Opsomer et al, 1996;DeJarnette et al, 2007). The poor reproductive performance observed in this study is attributable to the tropical conditions of Sudan under which the cows were reared, which has already been reported in Sudan (Abdel Gader et al, 2007) and in other tropical countries such as Ethiopia (Lobago et al, 2006), Egypt (Hassanini et al, 2002;Hammoud et al, 2010), South Africa (Goni et al, 2015), and West Africa (Obese et al, 2015). It is well known that the prolonged days from calving to conception are usually due to prolonged anoestrous (Chebel et al, 2006) or increased S/C (Badinga et al, 1985) or these factors together (Gilbert et al, 2005;Bahonar et al, 2009).…”

This study aimed to find correlations between blood glucose and urea levels and the duration of postpartum period (PPP), number of services per conception (S/C), open period (OP), conception rate (CR) to first service, and the overall CR in 80 multiparous cross-bred dairy cows. The two metabolites were measured 1, 4, 7, 10, and 13 weeks postpartum. The CR to first service and overall CR were 13.8% and 42.8%, respectively. Based on S/C, three groups were identified: Group 1 (G-1) (n = 11) consisting of cows that conceived from first service; G-2 (n = 46) representing cows that needed two inseminations to conceive; and G-3 (n = 23) consisting of repeat breeders (RB). G-1 represented 13.8%, with PPP and OP shorter than cows in G-2 and in G-3, and had blood glucose levels 17.5% and 27.9% higher than levels in G-2 and in G-3, respectively. Until the 7th week postpartum, blood levels of urea were higher in G-1 and lower in G-3. However, in the 10th and 13th weeks postpartum, results were reversed. The PPP, S/C, and OP were negatively correlated with blood glucose over the study period and with blood urea at the first seven weeks postpartum. However, these traits were positively correlated with blood urea measured at 10 and 13 weeks postpartum. It can be concluded that, from this study, maintaining high blood glucose until the 13th week postpartum, high blood urea during the first 7 weeks postpartum, and low blood urea during the 10th and 13th weeks postpartum were associated with good fertility in dairy cows. ______________________________________________________________________________________

“…In the same context, Vajdi et al [36] reported that glucose levels were significantly different between animals that become pregnant after first AI (artificial insemination) and those with failed to first AI. However, it seems that glucose may be associated with infertility when it is well below its usual values [37] .…”

“…Cystic animals had low concentrations of urea serum. In fact, several authors have studied the consequences of low urea levels on reproductive function in dairy cows; Miettinen [37] noted that reproductive function is impaired as soon as urea concentrations are less than 2.5 mmol/L. Enjalbert [41] mentioned that reproductive disorders appear only in cases of severe and prolonged nitrogen deficiency although it is rare.…”

A clinical study was performed to evaluate the diagnostic methods for ovarian cysts (OC), and to determine the metabolic profiles of animals with OC in the region of Mitidja in the North of Algeria. A total of 504 non-pregnant lactating cows were used in this study. Ultrasonography was performed by EXAGO scanner and was combined with assessment of serum P4. Biochemical serum parameters were assayed by spectrophotometry and insulin and cortisol serum measurement was performed by electrochemiluminescence. The results showed an overall incidence of 11.9% of OC. The incidence of OC was higher among cows in third lactation. Holstein breed was the most affected by OC compared with other breeds (P<0.001). There were no effects of average BCS (Body Condition Scoring) and milk production on the incidence of OC (P>0.05). OC were single in 91% of cases. They were found mainly on the right ovary (66.66%). Seasonality had a significant influence on incidence rate of OC with higher incidence rates during winter and spring (71.66%); while, 28.33% of OC were detected during the summer and autumn (P<0.05). OC were associated with low serum concentrations of glucose, insulin and urea as well as high levels of cortisol. Ultrasound examination and progesterone assays were proposed as the most effective diagnostic combination to diagnose OC. In conclusion, in addition to hormonal imbalances, metabolic disorders are involved in the formation and/or persistence of OC. Therefore, the use of metabolic indicators in understanding and exploration of OC is of great interest.

“…The solution is return the focus to indigenous genotypes that can already cope with local conditions and improve productivity by carefully planned use of reproductive technology and genetic and genomic tools ( 39 , 40 ). The simplicity of this approach is demonstrated by the introduction of Holstein genes to improve milk production in Sanga cattle in Ghana ( 41 ).…”

Since the 1990s, livestock industries have been forced to respond to major pressures from society, particularly with respect to methane emissions and animal welfare. These challenges are exacerbated by the inevitability of global heating and the effects it will have on livestock productivity. The same challenges also led to questions about the value of animal-sourced foods for feeding the world. The industries and the research communities supporting them are meeting those challenges. For example, we can now envisage solutions to the ruminant methane problem and those solutions will also improve the efficiency of meat and milk production. Animal welfare is a complex mix of health, nutrition and management. With respect to health, the ‘One Health’ concept is offering better perspectives, and major diseases, such as helminth infection, compounded by resistance against medication, are being resolved through genetic selection. With respect to nutrition and stress, ‘fetal programming’ and the epigenetic mechanisms involved offer novel possibilities for improving productivity. Stress needs to be minimized, including stress caused by extreme weather events, and solutions are emerging through technology that reveals when animals are stressed, and through an understanding of the genes that control susceptibility to stress. Indeed, discoveries in the molecular biology of physiological processes will greatly accelerate genetic progress by contributing to genomic solutions. Overall, the global context is clear – animal-sourced food is an important contributor to the future of humanity, but the responses of livestock industries must involve local actions that are relevant to geographical and socio-economic constraints.
