SUMMARYThe results of a nitrogen balance experiment with growing pigs have shown that 5 % feather meal was inferior to 7 % white-fish meal, when both supplements supplied the same amount of total crude protein in a barleyweatings- minerals-vitamins ration.A comparative feeding trial in which white-fish meal was partially replaced by feather meal in the diets given to growing pigs gave inconclusive results.

Beneficial Use

Nutrient depletion in Tanzanian sisal production has led to yield decreases over time. We use nutrient mass balances embedded within a life cycle assessment to quantify the extent of nutrient depletion for different production systems, then used circular economy principles to identify potential cosubstrates from within the Tanzanian economy to anaerobically digest with sisal wastes. The biogas produced is then used to generate bioelectricity and the digestate residual can be used as a fertilizer to address the nutrient depletion. If no current beneficial use of the cosubstrate was assumed, then beef manure and marine fish processing waste were the best cosubstrates. If agricultural wastes were assumed to have a current beneficial use as fertilizer, then marine fish processing waste and human urine were the best cosubstrates. The largest reduction in environmental impacts resulted from bioelectricity replacing electricity from fossil fuels in the national electricity grid and improved onsite waste management practices. There is significant potential to revitalize Tanzanian sisal production by applying circular economy principles to sisal waste management and bioenergy production.

Six male Landrace x Large White pigs (25 kg liveweight) were fitted with T-shape cannulae in the terminal ileum. The pigs were fed 1.2 kg dry matter per day containing 4.5 g threonine/kg of diet from continuous belt feeders. The apparent digestibility of dry matter (DM) to the terminal ileum was 0.91, 0.87, 0.85, 0.81, 0.80 and 0.75 for pigs given diets containing milk, fish meal, soybean meal, meat meal, sunflower meal and cotton seed meal respectively. The apparent digestibility of nitrogen (N) to the terminal ileum was 0.87, 0.87, 0.86, 0.86, 0.81 and 0.74 for pigs given diets containing milk, fish meal, soybean meal, sunflower meal, meat meal and cottonseed meal, respectively. The true digestibility of threonine to the terminal ileum was 0.96, 0.95, 0.90, 0.87, 0.80 and 0.66 for the diets containing milk, fish meal, sunflower meal, soybean meal, meat meal and cottonseed meal, respectively.

Daily Gain

Cinta Senese is characterized by slow growth rates, which implies different nutritional requirements compared to major pig breeds. Four different crude protein levels (120, 140, 160 and 180 g/kg on as-fed basis, denoted as CP12, CP14, CP16 and CP18) were tested to assess the optimal protein requirements of Cinta Senese pigs during the growing phase. The in vivo performance, slaughtering traits and nitrogen balance were evaluated using individual pens and metabolic crates. Increasing the protein level in feed lowered the average daily gain (from 0.76 to 0.71 kg/d), final weight (63.0 kg for CP12 versus 60.7 kg for CP16) and reduced the protein conversion efficiency (from 0.37 to 0.58). Also, protein conversion in lean protein linearly increased from CP12 (4.82) to CP18 (7.43), which implies a worsening in the protein utilization efficiency. The nitrogen balance showed higher loss of N through urine (from 0.68 g/d/kg metabolic weight for CP12 to 1.14 g/d/kg metabolic weight for CP18) as the dietary CP levels increased, and a decrease in the biological value (51.78 for CP12 versus 36.54 for CP16). The results indicated that the CP12 diet was adequate for fulfilling the Cinta Senese protein requirements during the growing phase.

Dry Matter Digestibility

Pig performance was compared on wheat based diets supplemented by two levels of either meat and bone meal or fish meal plus skim milk powder. The dry matter digestibility and nitrogen retention on these diets were determined and the effect of adding zinc to diets containing meat and bone meal was examined. At the higher level, fish meal plus skim milk powder produced greater daily gains between 60-160 lb than the meat and bone meal, but feed conversion and carcase lean were not affected. At the lower level, fish meal plus skim milk powder produced leaner carcases and greater daily gains between 60-160 lb than the meat and bone meal supplement, but had no effect on feed conversion. Between 60-100 lb, feed conversion was affected by level but not by supplement, and the higher level of fish meal plus skim milk powder produced greater daily gains than all other diets. The higher levels of each supplement produced greater nitrogen retentions and leaner carcases than the lower levels. Dry matter digestibility was least on the higher level meat and bone meal. Zinc supplements had no effect on performance.
