- Description: Tourism has been acknowledged for the past decade as one of the leading driving forces for economic development in post-apartheid South Africa (Nel & Binns, 2002:189). The objective of this study was to investigate the determinants of corporate entrepreneurship for firms in adventure tourism sector in the Eastern Cape Province; South Africa. The population for the study were firms registered with the Nelson Mandela Bay Tourism Portal (NMBT) and the Dirty Boot Adventure South Africa. Convenience sampling method was used. Data was collected through the use of a self-administered questionnaire. For the purpose of data collection, one hundred and fourteen questions were identified through a thorough review of the literature. Principal component analysis was used to reduce the one hundred and fourteen questions to twelve factors namely: flat organisational structure, management support for intrapreneurship, vision and strategic intent, rewards / reinforcement and sponsorship, innovativeness and creativity, multi-disciplined teamwork and diversity, entrepreneurial leadership, resources and time, strong customer orientation, continuous cross-functional learning, tolerance of risk, mistakes and failure and work discretion and discretionary time. Data was analysed using descriptive statistics, Pearson’s correlation, T-test and ANOVA. Cohen`s (d-value) was used to measure the effect size of differences for t-statistics. The Cronbach’s alpha was used to test the reliability of the scales. The results showed significant positive relationships between the twelve factors and corporate entrepreneurship. Recommendations included an integrated framework that could assist adventure tour operator to establish and sustain corporate entrepreneurship within this sector.

- Description: This study was designed was to determine the effects of additive supplementation of Moringa oleifera leaf meal on growth performance, digestibility, digestive organ size, intestinal integrity, bone ash content and bone breaking strength, as well as meat yield and quality of broiler chickens. A total of 2400 day-old unsexed Cobb-500 broiler chicks were randomly allocated to 5 treatment groups: T1, positive control, 668 g/ton Salinomycin and 500 g/ton Albac; T2, T3 and T4 contained graded levels of MOLM at 1 percent, 3 percent and 5 percent of dry matter (DM) intake, respectively; and T5, a negative control (0 percent additives) in a complete randomized design experiment. Except for week one, FI and FCR was highest (P < 0.05) in T4 birds; while T1 birds had the highest FI in the period of 22 to 27d (P < 0.05). Throughout the production period, birds supplemented with MOLM had the highest BW (P < 0.05) than the birds fed the control diets. Feed intake (FI) and feed conversion ratio (FCR) among treatments was highest (P < 0.05) in T4 birds during the period of 8 to 14 d; and was highest (P < 0.05) for T1 birds in the period of 22 to 27d. Protein efficiency ratio (PER) and energy utilization efficiency (EEU) ratios were statistically significant among treatments (P < 0.05). However, dietary treatments had no effect (P > 0.05) on the weights of the heart, liver, spleen, or the gizzard, although the bursa for T2 birds was the lightest (P < 0.05); while gizzard erosion score was highest in T2 birds. All of the nutrients measured, except for fat, had negative intercepts that were significantly different (P < 0.05) from zero, indicating the presence of endogenous fecal losses. Tibiae length (TL) was highest in T2. The dried defatted weight (DW) was heaviest (P < 0.05) for T3 (11.20 ± 0.347) and T5 (11.08 ± 0.328). A positive correlation (r = 0.667; P < 0.01) between TW and DW was observed. There were no dietary effects on bone breaking strength (BBS), but T1 tibiae had highest resistance to breaking force (T1 > T4 > T3 > T2 > T5). Calcium was highest (P < 0.05) in T1; and lowest inT2 and T5. Phosphorus levels were lowest (P < 0.05) in T1; and highest (P < 0.05) in T5 compared. The highest Ca: P ratio was obtained in T4 (P < 0.05); while the ash percent was highest (P < 0.05) in T1. Drip loss increased as L* values increased; and a negative correlation was observed between L* and pH. On D1, C18: 0 and C22 in T2, while C15:0 was highest in T4. On D1, C20:2, C20:3n6 and C22:6n3 were highest in T2 (P < 0.05); T4 had the highest C18:3n6 (P < 0.05), while C20:2 was highest in T5 (P < 0.05). The P/S ratio on D1 was highest in T4; while n-6/n-3 was highest in T1; and n-3 was highest in T3. On D8, the n-3 was highest in T1 (P < 0.05). Results of the current study show that supplementation of M. oleifera leaf at additive levels of up to 5 percent of the bird’s DMI does have the potential to influence the bird performance without any detrimental effects on nutrient utilization, bird health, bone strength and/or meat quality, which can be concluded that MOLM enhanced the bird’s genetic potential for optimal productivity.
