The project is generating knowledge on how to implement mixed portfolios of built water infrastructure (e.g., dams, levees, irrigation channels) and 'natural infrastructure' (e.g., wetlands, floodplains, forests) that contribute to poverty reduction; water, energy and food security; biodiversity conservation; and climate resilience at a landscape scale. 'WISE-UP to Climate' aims to demonstrate the application of optimal portfolios of built and natural infrastructure developed through dialogue with stakeholders and decision-makers at multiple levels (local to national) to identify and find consensus on trade-offs. The project also seeks to link ecosystem services to water infrastructural development in the Volta River Basin (Ghana principally, and also Burkina Faso) as well as the Tana River Basin in Kenya.

The weight of darn at service and birth weight of lamb averaged 48.66±1.14 and 3.67±0.08 kg, respectively. It has been observed that weight of the dam significantly effect the birth weight of lambs. The correlation and regression coefficients between the above mentioned two traits were 0.30 and 0.042±3.157×1-3. Analysis of variance of weight of the dam at service and birth weight of lambs due to regression revealed that this regression is statistically significant (p<0.01). The results of the present study indicated that the dams weight had a positive relationship with birth weight of lambs which will be helpful in the selection of young lambs even before their birth.

Data were collected from weight records of buffalo calves raised at Mahallet Mousa Farms belonging to the Animal Production Research Institute. It included 2015 progeny of 125 sires, through 17 consecutive years. Effect of inbreeding was highly significant for all studied traits. The overall average of inbreeding coefficient was 0.53% in whole population and 15% in the inbred animals. The means of BW, PDG and WW in non-inbred group were 37.318, 0.490 and 88.86 Kg, respectively. While, the means of the same traits in inbred group were 31.96, 0.446 and 78.82 Kg, respectively. Corresponding the inbreeding depression as overall means of levels for above traits were-0.350,-0.003 and-0.716, respectively. Direct heritability (h 2 a) in inbred animals for BW, PDG and WW were 0.28, 0.25 and 0.19, respectively. On the other hand, the h 2 a of studied traits in non-inbred animals were 0.32, 0.30 and 0.23, respectively. The maternal heritability (h 2 m) for mentioned traits were 0.25, 0.26 and 0.21 within inbred animals and 0.29, 0.28 and 0.22 within non-inbred animals, respectively. Likewise, the genetic correlations (r g) among studied traits were ranged from (0.12 to 0.56) in inbred animals and were ranged from (0.16 to 0.63) in non-bred animals. As well the phenotypic correlation (r p) among studied traits were ranged from (0.04 to 0.50) for inbreds and were varied between (0.04 and 0.54) for non-inbreds. The inbreeding was pronounced detrimental effects of studied traits in buffalo calves. Therefore, breeding strategies should be develop for reduce the inbreeding effects and inclusion the effects of inbreeding in genetic evaluation programs in Egyptian buffalo calves.

The average age of the dam at service was 1337.57 ± 10.55 days. The least-square means for birth weight were 3.63 ± 0.11 and 3.41 ± 0.07 kg for single male and female lambs and 3.45 ± 0.12 and 3.29 ± 0.12 kg for male and female lambs born as twins. Age of the dam at service had a significant relationship with the birth weight of lambs. The correlation and regression coefficients between the above mentioned two traits were 0.37 and 0.025 ± 0.0001, respectively. Analysis of variance of age of the dam at service and birth weight of lambs due to regression revealed that this regression was statistically significant (P<0.01).

Data on 17030 birth records of 5421 Thalli sheep maintained at Livestock Experiment Station, Rakh Ghulaman, district Bhakkar during 1975-2004 were utilized in the present study with the aim to evaluate the performance of Thalli sheep in Pakistan. The genetic parameter estimation was performed using REML procedure by fitting an Individual Animal Model. Birth weight with an average of 4.11±0.82 kg, was significantly affected by year, type of birth, sex and age of the dam but season of birth was an in significant effect on the birth weight. Weight at 60 and 90-days of age averaged 11.58±3.57 and 14.92±4.56 kg, respectively. These weights were affected by year and season of birth, birth weight. Type of birth and sex had significant effect on weight at 60 days of age where as age of the dam had non-significant effect on weight at 60 days of age. Age of the dam significantly affected 90-day weight. Sex and type of birth h...
