This study evaluated the protein requirement of Litopenaeus vannamei post-larvae during the initial rearing phase in a biofloc system. Five different diets were evaluated with increasing concentrations of crude protein: 31.28, 36.29, 41.57, 46.34, and 51.74 g 100 g-1 CP. Post-larvae (0.16 ± 0.01 g) were stocked at a density of 450 PL m-3 in 400 L tanks. Water quality parameters were maintained within the limits recommended for shrimp farming. After 38 days, a regression analysis revealed that levels of CP content (65.29 – 72.83%), EE (10.45 – 11.65%) and body N (10.45 – 11.64%) increased with increasing protein levels in the diet. A similar trend was observed in the biofloc sludge with respect to CP and N. Survival exceeded 80%, and the shrimp with diets containing 31.28 to 46.34g 100 g-1 CP presented an increase in final weight (1.52 – 2.61 g), productivity (0.69 – 1.10 Kg m-3), weight gain (1.38 – 2.44 g), and feeding efficiency (77.28 – 101.68%), whereas these indices decreased to51.74 g 100 g-1 CP. Crude protein content from 44.26 to 47.12 g 100 g-1 provided the best growth performance during the initial rearing phase of Pacific white shrimp in a biofloc system.

SUMMARYFeeding trials were carried out at different times of the year to determine the optimum crude protein requirements of weaner and growing pigs, using principally the locally available ingredients. The animals used were 96 weaners and 113 growing pigs of the Large White and Landrace breeds of average initial weights of about 9 kg and 41 kg respectively. Test diets contained protein levels ranging from 12% to 24% on a dry-matter basis, and the pigs were mostly group-fed ad libitum except for one trial. Average daily gains, efficiency of feed utilization, apparent nitrogen retention and digestibility, and feed cost per kg of body gain were measured. In a humid tropical environment, such as Ibadan, the optimum crude protein requirement for weaner pigs from 9 kg to 34 kg live weight is between 22 % and 24 % of dry matter, while that for the fattening pigs from 41 kg to 82 kg live weight is between 18% and 21% of dry matter.

SUMMARYNitrogen balance studies of latin square design were conducted on six adult rams receiving diets with approximately 4, 8 and 16% crude protein. The diets were almost isocaloric and contained groundnut cake, wheat bran, maize starch, and chopped wheat straw. Metabolic faecal and endogenous urinary N were 0·24 ± 0·003 g/100 g dry-matter intake and 0·038 ± 0·01 g/kg body weight per day. Biological value, true digestibility and coefficient of net utilization were 86·9 ± 8·68, 93·4 ± 1·94 and 79·6 ± 2·47, respectively.Daily digestible crude protein requirements for maintenance estimated by the factorial method (0·875 + 0·;06 g/kg W0·734) and from N balance and the net utilization of protein (0·893 + 0·03 g/kg W0·734) were similar but slightly higher than the requirement estimated from N balance alone (0·738 ± 0·04 g/kg W0·734). All values are lower than the conventional recommendations.
