- Description: The objective of the study was to determine the management factors influencing lamb survival from birth to weaning in two ecologically different resource-limited communal farming systems. An annual flock monitoring study in the sourveld and sweetveld regions was preceded by a household check-all-that-apply (CATA). Lamb management practices and constraints faced in raising lambs in the two regions were determined using the check-all-that-apply technique. The results showed that the majority of the households were male headed (75.70percent) and consisted of the elderly (˃50 years, 79.44percent) who were not employed (82.24percent) and had attended primary school (67.29percent). Wool production was ranked the most important reason for keeping sheep in the two regions. The CATA revealed that the management systems between the two regions differed significantly (p˂0.05) in terms of assisting sheep at lambing, attending to twin births and dipping of mature lambs. Farmers‘ age was associated with the type of management performed (p ˂0.05). None of the farmers in the two regions performed navel dipping. Some of the reported constraints in the sweetveld were theft, diarrhoea and drought while predators and cold weather were the major constraints in the sourveld. The CATA identified vaccination and dipping as the major missing practices in both regions. The study showed differences in the use and choice of CATA terms which suggests that a ―one-size-fits-all‖ approach to solving poor management and sheep production constraints is not applicable. In the monitoring study, the results showed that veld type had no significant effect on the birth weights (2.0±0.09 kg) of the lambs. Type of birth had a significant effect (p<0.05) on the birth weights of the lambs. Single born lambs were 0.41kg heavier (p<0.05) than twin lambs. Single born lambs, however, showed an improvement in weights at 90 and 120 days where they had slightly higher weights than single born lambs. Male lambs were significantly (p<0.05) heavier (2.3±0.12 kg) than the female lambs (1.7±0.06 kg) at birth. The lamb birth were highest (P<0.05) in the hot-dry season. Lambs born in the cold-dry season were the lightest (1.63±0.13 kg). Lambs born in the post- rainy and hot-wet season were not significantly different (P<0.05). Weaning weights were not affected by veld type, birth type and sex, but were affected by season of birth. The lambs born in the hot-dry season had the highest weaning weights. The sourveld had a total pre-weaning mortality of 10.6percent while the sweetveld had a total pre-weaning mortality of 14.2percent. Animal housing from both veld types was poorly designed in terms of security against stock theft, drainage, hygiene, overhead shelter from the rain as well as access to feed and water. It was concluded that lamb management practices in the two regions were not the same. Performance of lambs before weaning differed according to veld type which played a role in feed availability during different seasons.

- Description: This study focused on the technical and institutional constraints faced by the vegetable co-operatives with regard to the impact on productivity. Vegetable co-operatives have no access to markets due to their poor performance on productivity and poor quality produce resulting to low prices for the produce such that they cannot compete in a market economy. In this study, the data was drawn from a sample of thirty vegetable co-operatives in the Buffalo City Metropolitan Municipality (BCMM) of the Eastern Cape; obtained through focus group discussions and interviews from each cooperative. The objectives of the study are to measure the productivity of vegetable co-operatives using Total factor productivity analysis (TFP) and profitability of vegetable co-operative using Gross Margin (GM). Followed by the descriptive statistics in identifying and assessing the socio-economic characteristics as well as coping strategies adopted by vegetable co-operatives in BCMM where percentages, means and tables are used looking at the highest frequency. The results show that the vegetable co-operatives in the BCMM are not productive and profitable due to major constraints experienced by co-operatives such as lack of market, information, trainings and business skills, capital, infrastructural facilities, effective extension services that all leads to poor produce quality. Co-operative is said to be profitable and viable if total revenue is greater than the total variable cost which makes the gross margin positive. In this case, the total gross margin is negative. The results showed that the production costs, maintenance (tractor hire, generator hire and servicing) and electricity costs were the major costs incurred in the production of vegetable by the co-operatives.
