This study aimed to examine the impact of dietary salt-based mineral and phosphorus supplements on mean body weight, survival rate, and feed conversion ratio of Litopenaeus vannamei (white shrimp) reared in brackish water. The experiment was performed randomized design with three replicates in each treatment used twelve 40 L rectangular polymethyl methacrylate containers reared 45 days. The four treatments in this study were based on the concentration of salt-based mineral and phosphorus supplements (control or 0 ppm, one ppm, two ppm, and three ppm) in dietary of white shrimp. The results showed that using salt-based mineral and phosphorus supplements in dietary of white shrimp positively impacts mean body weight, survival rate, and feed conversion ratio. Increasing the concentration of salt-based mineral and phosphorus supplements increased mean body weight and survival rate and reduced feed conversion ratio of white shrimp. The mean body weight, survival rate, and feed conversion ratio of white shrimp were achieved with three ppm of dietary salt-based mineral, and phosphorus supplements reared 45 days was 5.98 gr, 88.57%, and 1.45, respectively.

This study was carried out to evaluate the impact of raw and cooked wild cocoyam (Caladium bicolor) on the performance of broiler chicks. Wild cocoyam corms were divided into two batches. One batch was ground raw and the other batch was cooked before grinding. Wild cocoyam meals so prepared were used to formulate 5 broiler starter diets at dietary inclusion levels of 0, 10 and 20% raw and cooked wild cocoyam respectively. 180 7-day-old Anak broiler chicks were randomly allotted to the five treatment diets in a Completely Randomized Design (CRD) and each group was further subdivided into three replicates of 12 birds. Measurements recorded included weight gain, feed intake, feed conversion and protein efficiency ratios and economics of production. Results shows significant (p<0.05) improvement in feed intake, weight gain, feed conversion ratio and PER of birds fed cooked wild cocoyam meals. Marked (p<0.05) reduction was however, obtained in feed intake and feed conversion ratio of birds fed raw wild cocoyam diets. There was no significant (p>0.05) difference between birds fed maize-based (control) and cooked wild cocoyam diets. Results of this experiment indicated that cooking improved the nutritive value of wild cocoyam since birds fed cooked wild cocoyam diets produced best results than those fed raw wild cocoyam meal and that starter broilers could tolerate up to 20% dietary inclusion level of cooked wild cocoyam without any deleterious effect. Economics of production showed that cooked wild cocoyam diets were more profitable as regards the cost of feed per kg weight gain (N) and thus cost savings (%).
