“…However, Amle et al (2014) stated that blood urea nitrogen did not differ in RB and normally cycling cross-bred dairy cows in India. On the contrary, Ali et al (2014) related that a group of non-pregnant dairy cows exhibited comparatively lower blood urea levels compared with a pregnant group. Among the explanations for the mechanisms by which urea can affect the fertility of dairy cows, Elrod & Butler (1993) reported that feeding high rumen degradable protein to heifers results in increased blood urea nitrogen concentration and decreased uterine pH, which adversely affect the motility and viability of sperms and hence the pregnancy rate.…”

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. ______________________________________________________________________________________

“…The Government of Pakistan established a national policy for cattle breeding, which allowed relative breeding for both native and non-descriptive breeds of cattle (Ali et al, 2014) through use of exotic semen (Khan and Rehman, 1994). Two breeding strategies are available for genetic improvement of cattle i.e., selective breeding within the breed and crossbreeding among the breeds (Faleconer and Mackey, 1996).…”

“…The dry period of 89 -1200 days for Red Sindhi and 86 -140 days in Crossbred cattle was found in present study. The dry period was reported from 75-1200 days in the literature in different breeds of cows (Haque et al, 2011;Qureshi et al, 2002;Kathri et al, 2004;Kakar, 2001 Milk yield is a multifactorial trait which dependent on genetic, breed, age, parity, stage of lactation, season, health status, nutrition, management and staff itself involved (Ali et al, 2014).…”

“…The reproductive and productive performance of indigenous cattle breed is relatively lower, due to un-exploited genotype and poor nutrition (Ali et al, 2014;Kumar et al, 2014;Boby et al, 2013;Haque et al, 2011). The indigenous breeds of cattle have strong disease resistance and are able to thrive best in extreme climatic conditions, whereas exotic breeds have problems of less tick resistance and susceptible to various contagious diseases (Islam and Bhuihyan, 1997).…”

| The study was carried out at Nagori Dairy Farm, Karachi, Pakistan to investigate the reproductive and productive traits of twenty Crossbred (Holstein-Friesian x Red Sindhi cattle 50% blood level) and twenty Red Sindhi cattle under intensive management conditions. A significant (<0.05) difference was found between the groups for age at puberty, age at first calving, calving interval, 1st post-partum estrus. Mean values for these traits were 616. . No significant (>0.05) difference was found for service period and dry period between groups. Mean values for service period and dry period were 124.15 ± 10.162 and 89.700 ± 0.596 days in Red Sindhi cows and 181.700 ± 59.199 and 86.950 ± 5.504 days in Crossbred cows. Both groups (Red Sindhi cattle and Crossbred cattle) calved normally at 75% and 65%, respectively. Normal expulsion (within 6-8 hrs.) of placenta was 85% in Red Sindhi and 80% in Crossbred cattle. In conclusion, reproductive and productive performance of Crossbred cattle was significantly superior to the local cattle breed in the study area.

| The aim of present study was to investigate the probable effects of the reproductive state on the sera component and enzymes in lactating and pregnant sheep. All the blood tests were carried out in 46 healthy sheep. The animals were divided into three groups: first group (G1; n = 15) pregnant, the second group (G2; n = 16) lactating and third group (G3; n= 15) non-pregnant and non-lactating (control group). The results showed that higher concentrations (P< 0.05) of total protein were determined in the blood of pregnant sheep compared to lactating group sheep. Moreover, the alkaline phosphatase (Alp) activities were higher (P< 0.01) in lactating sheep than pregnant and control group, while higher (P< 0.01) concentrations of acid phosphatase (Acp) activity were determined in sera of pregnant compared to lactating and control sheep. The results further showed the higher (P< 0.05) specific activity of Acp in pregnant compared to lactating and control. The higher (P< 0.05) specific activity of Alp were also determined in sera of lactating compared to pregnant and control. The lowest (P< 0.05) sera Zn+2 and Mg+2 levels in pregnant sheep were observed compared with lactating and control group A. Results of this study showed that values of Acp, Alp activities and total protein could be used as an indicator of pregnancy in sheep. We suggest that pregnancy and lactation periods must be taken into consideration for the true interpretation of sera chemistry and ions status in sheep.
