THE DETERMINATION OF NUTRITIVE VALUE OF FRUIT AND VEGETABLE WASTES USING DIFFERENT MATHEMATICAL MODELS

Background: This study was carried out in order to determine the nutritive value of fruit’and vegetable wastes using in suit technique. The objective of this study was to determine in situ CP degradability of fruit and vegetable wastes using nylon bag technique and survey to use this feed as animal feedstuffs.

Methods: Two fistulated wethers (35±1.8 kg) were used in the nylon bag method. The crude protein and dry matter disappearance were measured at 0, 4, 6, 8, 12, 16, 24, 48, 72 and 96 h. CP (Crude Protein) degradability of carrot wastes at 96h was 64.56 that were higher than the vegetable waste and that showed significant differences (p<0.05). Dry matter degradability of vegetable wastes at 96h was 68.58 % that was the highest and shown significant differences (p<0.05).

Results: Results of this study were showed that model 4 for carrot wastes and model 2 for vegetable wastes were the best-fitted models. The output of this model showed that model 2 was the best model for measuring a Dry matter of carrot wastes and model 1 was better for measuring a Dry matter of other vegetable wastes.

Conclusion: Fruit and vegetable wastes showed high ruminal degradation of CP (Crude Protein) as same as other economical feedstuffs, and these can be used instead of other feedstuffs. It should also be noted that models 3 and 4 did not achieve convergence in vegetable wastes.
