Range forages consumed by free-range goats are commonly deficient in protein, energy and minerals resulting in low productivity of the goats. The main objective of this study was to evaluate the effect of whole pumpkin seed meal supplementing diet on growth performance and semen quality of free-range goats. Thirty Malawian local bucks with an initial weight of 12.4±0.3 kg and age of 6 months were studied in completely randomised design. The treatments were: free-grazing with either supplementing diet of pumpkin seed meal or soybean meal and grazing only. The supplementing diets were mixed with maize bran to make them comparable. The supplementing diets were offered to goats (500 g each goat) before grazing (7:00 am) in individual pens followed by free graze for 7h. The experiment ran for 150 days. The measurements included: feed and refusals of the supplementing diet, live body weight, scrotal circumference and semen quality characteristics. The intake of supplementing diets was high in bucks consuming soybean supplementing diet than pumpkin seed meal supplementing diet (P = 0.0489). Bucks supplemented with either soybean or pumpkin seed meal had higher final weight and average daily gain (P < 0.05) than the non-supplemented goats. However, the final live body weight and average daily gain did not differ (P = 0.639) between goats on soybean and pumpkin seed meal supplementing diets. The bucks supplemented with pumpkin seed meal had the widest scrotal circumference (P < 0.05) of all the treatments studied. The bucks fed a supplementing diet containing pumpkin seed meal had higher semen pH (P < 0.05) than bucks on sole grazing group and soybean supplementing diet. Bucks on pumpkin seed supplementing diet had the greatest scores (P < 0.05) on total sperm motility and progressive motility; and sperm concentration followed by the bucks on soybean and the bucks on grazing only had the lowest score. The whole pumpkin seed meal could be used to improve productive performance and semen quality characteristics of free-ranging bucks.

This paper describes a study aimed at evaluating the effect of selecting sires based on their breeding values for milk yield estimated in their countries of origin on reproductive performance of their daughters on large-scale dairy farms in Malawi. To do this an analysis was done using 2362 records of purebred Holstein Friesian cattle kept in Central and Southern Malawi from 1986 to 1996. Fixed effects of sire group, herd, year and season of calving were tested and random effects of dam and cow were included in the statistical model applied. (Co)variance components were estimated through the restricted maximum likelihood (REML) procedure. Mean number of services per conception (NSC) was 1.50, gestation interval (GI) was 277days, calving interval between first and second parity (CI1) was 416 days, calving interval between second and third parity two and three (CI2) was 408 days, and age at first calving (AFC) was 32.5 months. In general the majority of the reproductive traits were affected by the non-genetic factors of herd, year and season. Sire group, a proxy of the breeding strategy, had a significant effect on AFC (p<0.01) and CI2 (p<0.05). Factors that had significant effects (p<0.01) on most of the reproductive traits in the study were herd, year of insemination, year of calving, and season of insemination. Phenotypic correlation between NSC and AFC was 0.19, between NSC and GI was -0.05, while that between NSC and CI2 was 0.14. Heritability estimates for NSC, GI, CI1, and AFC were, 0.04, 0.10, 0.001, and 0.20, respectively. The high variation due to non-genetic factors and the low heritability estimates for the reproductive traits indicate that much improvement could be made through improved management, husbandry practices, and strategically utilizing environmental factors.

Disappointment was widespread when rapid economic growth since 2005, coupled with a smallholder-targeted fertilizer subsidy program, failed to significantly reduce poverty in Malawi. Official estimates for 2011 showed a 1.7 percentage point decline in national poverty between 2005 and 2011, while rural poverty increased marginally. In this study we estimate an alternative set of regional poverty lines using a cost of basic needs method that allows the consumption bundle to vary spatially and temporally while ensuring utility consistency. Our poverty figures suggest a substantial 7.3 percentage point decrease in national poverty over the analysis period, driven largely by a sharp reduction in rural poverty. These results are more consistent with the observed level of economic growth and improvements in several non-monetary dimensions of well-being. However, we find that extreme poverty did increase, suggesting that the most vulnerable people continue to be excluded from the benefits of economic policy and growth.
