24 Large White X Landrace pigs weaned at 28 about 10% of the total feed is said to offer days with initial liveweight of 5.27±0.23 kg were valuable additional micro-nutrients such as fed four animal protein concentrates (fish meal However, almost all the fish (FM), Chicken offal meal (COM), fresh blood meal (FBM) and parboiled blood meal (PBM) diets based on full-fat soybean (FFSB) for 8 prices weeks to test different animal protein sources of protein and for early weaned pig. The diets contained 23% crude protein and 3100 Kcal ME/kg diet. Blood meal slightly reduced weight gain and feed intake but compared favourably with fish meal and chicken offal meal in efficiency of feed utilization. Parboiling of the blood slightly (P>0.05) depressed the performance of the pigs;even when the pigs had the same feed intake.. Fish meal increased (P<0.05) serum total protein and serum albumin levels.This study indicated that early weaned pigs fed soybean based diets supplemented with chicken offal meal and blood meal gave similar performance to those fed diet supplemented with fish meal.

The experiment was done in the experimental station ÚKZÚZ Havlíčkův Brod. There were four experimental groups (N1, N2, N3, N4) of laying hens and weekly laying intensity was observed. Hybrid ISA BROWN was used in the experiment, 405 hens in each group. The laying intensity was observed from the start of laying for 44 weeks. During laying four different diets were fed to laying hens (N1 – control group with fish meal, N2 – control group containing only of plant protein sources, N3 – experimental group with higher content of rapeseed, N4 – experimental group containing treated rapeseed). Yang model was used for the evaluation of laying curves and we found following parameters of the curves:Yang model N1: y = 97.28 * e – 0.004 * t / [1 + e – 2.054 (t – 2.549)] R2 = 0.97Yang model N2: y = 98.29 * e – 0.006 * t / [1 + e – 2.071 (t – 2.668)] R2 = 0.96Yang model N3: y = 98.49 * e – 0.005 * t / [1 + e – 1.856 (t – 2.568)] R2 = 0.97Yang model N4: y = 98.55 * e – 0.005 * t / [1 + e – 2.251 (t – 2.615)]. R2 = 0.97The results document that experimental treatments had small effect on the parameters of laying curves. It means that rapeseed had only small effect on the laying intensity and also the elimination of animal protein from the diet for laying hens had not effect on laying intensity. On the base of our results we estimated the standard equation for evaluation of laying curve:Yang model: y = 98.15 * e – 0.005 * t / [1 + e – 2.058 (t – 2.601)]. R2 = 0.99This equation can be used as standard for evaluation of laying intensity after experimental treatments or for evaluation of laying intensity of different hybrids.

Yellow mealworm (Tenebrio molitor) larvae are a potential alternative animal protein source for sustainable aquaculture. However, reports on the successful complete substitution of fish meal with yellow mealworm larvae in an aquaculture diet have been limited. In this study, we conducted a feeding trial with red seabream (Pagrus major) being fed diets with partial or complete replacement of fish meal with yellow mealworm larvae defatted with a hexane–ethanol solution. Feed intake in red seabream increased in accordance with yellow mealworm larvae inclusion, and diets including 65% defatted mealworm larvae (complete replacement of fish meal) showed significant growth promotion. The addition of the oil fraction from mealworm larvae to diets resulted in growth reduction, despite meeting the nutritional requirements of red seabream. Moreover, the survival rate of red seabreams fed diets with partial replacement of fish meal with mealworm larvae was significantly higher in a challenge test with pathogenic Edwardsiella tarda bacteria. The present study demonstrated that yellow mealworm larvae are not merely an alternative animal protein, but have potential as functional feed ingredients for aquaculture production.

A study was carried out to compare the use of blood meal and fish meal as protein sources in single phase feeding of broiler chickens.  Three isonitrogenious and isocaloric diets containing between 20.5 to 21.1 % CP and 3440 to 3454 kcal/kg ME were formulated. The control diet contained none of the animal protein sources while the other two diets contained blood meal and fish meal at 6%, respectively. After six weeks of straight feeding, data were collected on feed intake, weight gain and feed conversion ratio was calculated. Carcass characteristics and cost benefit were also calculated. The results indicated that birds fed fish meal based diet  consumed more feed (p< 0.05) than those on control diet,  while intake of those on blood meal based diet  was an interphase between the control and fish meal based diet groups. The birds fed fish meal based diet also recorded higher (p< 0.05) daily weight gain than those on control and blood meal based diets. Feed conversion ratio was better in the group fed fish meal based diet than those fed the control diet, but similar (p> 0.05) to the group fed the blood meal based diet. The dressing percentage of the birds was similar (p>0.05) in the control and blood meal based diet groups, but they were higher (p<0.05) than the fish meal based diet group. The neck, back, drumstick and head were significantly (p<0.05) higher in the control group than in the groups containing animal protein. Cost benefit analysis showed that feed cost and cost per kg weight gain were higher (p< 0.05) in fish meal based diet group than in control and blood meal based diet groups. Revenue per bird and gross margin were higher (p< 0.05) in the blood meal based diet group than in the control diet and fish meal based diet groups. In conclusion, fast growing broiler chickens for eatery houses can be better reared with a single diet of 21 % CP and 3440 kcal/kg ME using blood meal as a protein source.   Keywords: , , , , , ,
