Dietary Fish

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

Adaptation To Captivity

Abstract Seriola lalandi is an important species for aquaculture, due to its rapid growth, adaptation to captivity and formulated diets, and high commercial value. Due to the rise in fish meal (FM) price, efforts are made to replace it partially or entirely with vegetable meals in diets for carnivorous fish. The use of prebiotics when feeding vegetable meals has improved fish health. In this study, four experimental diets were assessed in juveniles, the control diet consisted of FM as the main protein source, the second diet included 2% GroBiotic®-A (FM-P), the third included FM with 25% replacement by soybean meal (SM25), and the fourth consisted in SM25 with 2% of GroBiotic®-A (SM25-P). RNA-seq of the liver tissue was performed, followed by differential expression analysis and functional annotation to identify genes affected by the diets. Growth was not affected by this level of FM replacement, but it was improved by the prebiotic. Annotation was achieved for 78,826 transcripts, of which 135 were up-regulated and 78 down-regulated among all treatments compared to the control. Transcriptomic profiles of control samples were clustered with those from fishes fed SM25 and SM25-P diets, and the most differentiated group was that one fed the FM-P diet. SM25-P showed the least amount of differentially expressed genes, maintaining general transcriptomic profiles of control diet in the liver, therefore this diet is a potential economic alternative to the FM diet, for S. lalandi juveniles. Assessment of the effects of this diet along the digestive tract is recommended.

Finisher Diets

Two experiments were conducted to evaluate the nutritional value of Brassica napus 'Tower' rapeseed meal (Tower RSM) and B. campestris 'Candle' RSM or combinations of Tower RSM and fish meal (FM) or Candle RSM and FM as partial or complete replacement for soybean meal (SM) in chicken broiler starter and finisher diets. Amino acid levels were maintained in diets where SM was replaced by RSM by increasing the level of FM. The results of these experiments indicate that RSM can replace up to 80% of the SM in chicken broiler starter and finisher diets on a straight replacement basis without adversely affecting body weight or feed efficiency. Moreover, RSM can replace all of the SM in such diets without adverse effects on biological performance provided energy, protein and amino acid differences are compensated. The calculated amino acid content of the diets indicate that FM is a complementary source of dietary protein in diets containing high levels of RSM.
