Laying hens (53 weeks old) were fed a basal diet with 9% fish meal and diets in which housefly maggots (Musca domestica, Linn) replaced 33.3, 66.7 and 100% of the fish meal in the basal diet during a 6-week trial period.  Average daily feed intake were 125.1, 115.1, 109.1 and 105.7g respectively (P<0.05).  Corresponding total weight gain per bird during the trial period were 210, 180, 20 and 37g respectively (P<0.05). There was however no significant effects of increasing dietary level of maggots on egg production, egg weight or feed/dozen eggs (P>0.05). There was also no significant effects of the treatments on protein or fat retention by laying hens. It is concluded that housefly maggots could replace fish meal (9%) in layer's diet without detrimental effects on their performance. Maggots is a cheap alternative to fishmeal in laying hen diets, the cost of its production being only 15% of the equivalent weight of fishmeal.

Dietary Treatments

Alternative growth promoters are able to not only effectively replace the traditional use of antibiotics but also provide additional health benefits for livestock and reduce food safety concerns. This study investigated the effects of dry Hydrastis canadensis on the laying performance and fecal microbial community of laying hens. Twenty-four Lohmann (LSL, white layer strain) hens were reared from 40 to 48 weeks of age and randomly allotted to four dietary treatments (six birds/treatment). The dietary treatments comprised a basal diet with no treatment as control, a basal diet plus 0.6% powder of dry Hydrastis canadensis roots (R) or leaves (L), and a basal diet plus 0.6% powder of a mixture of dry Hydrastis canadensis roots and leaves (1:1, LR). No mortality was observed in the whole experimental period. The results indicated that albumen height in the LR group was significantly greater than that in the control group. The diet supplemented with Hydrastis canadensis had no significant effects on egg production rate, egg weight, eggshell strength, eggshell thickness, Haugh unit, or yolk height during the whole experimental phase. However, principal coordinate analysis, comparative heat map analysis, and cluster dendrogram analysis of cecal microbiota showed distinct clusters among the groups treated with Hydrastis canadensis and the control group. Regarding blood biochemical parameters, serum cholesterol levels were significantly lower in all Hydrastis canadensis-treated groups compared with those in the control group. Moreover, serum low-density lipoprotein levels were lower in hens supplemented with the leaf of Hydrastis canadensis. The abundances of the phyla Fusobacteria and Kiritimatiellaeota were increased (p < 0.05) in laying hens fed with 0.6% Hydrastis canadensis leaves, whereas the abundance of the phylum Firmicutes in cecum digesta decreased in response to treatment with Hydrastis canadensis roots and leaves. The relative abundance of the Fusobacterium genus was higher in the LR group compared with that in the control. On the contrary, we found a different trend in the Synergistes genus. The potential influences of these microbiota on the performance of laying hens were discussed. The results demonstrate that Hydrastis canadensis can improve the egg albumen height and modulate the cecum digesta microbiota composition of laying hens.

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.

An experiment was carried out to investigate the effect of Bacillus subtilis RX7 and B2A supplementation on egg production, egg quality, blood profile, and excreta Salmonella population in laying hens. A total of 192 Hy-Line Brown laying hens (40-wk-old) were randomly assigned into four dietary treatments, each of which was replicated eight times with six hens per replicate in a 5 wk trial. The dietary treatments were NC, which is a basal diet without antibiotics or Bacillus subtilis; PC, which is an NC + 0.5 g kg−1 antibiotic (virginiamycin) diet; BSR, which is an NC + 0.5 g kg−1 Bacillus subtilis RX7 (1.0 × 109 colony forming units g−1); and BSB, which is an NC + 0.5 g kg−1 Bacillus subtilis B2A (1.0 × 109 colony forming units g−1). The results showed that hens receiving BSB diets had increased (P < 0.05) eggshell thickness over hens fed the NC, PC, and BSR diets (week 3). The excreta Salmonella counts in the PC, BSR, and BSB groups were lower than the NC group (P < 0.05). These results indicate that dietary inclusion of Bacillus subtilis RX7 and B2A strains effectively decreased excreta Salmonella counts without any detrimental effects on the performance of laying hens.

Experimental Group

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.

The objective of this study was to compare the effects of feed supplementation of laying hens with manganese from its inorganic and organic sources on performance and some parameters of egg quality. Ninety-six hens at 20 weeks of age were randomly allocated to 4 dietary treatments, each consisting of 6 replicates (4 birds per replicate). The control group was fed unsupplemented basal diet (BD) with only natural background Mn level of 46.4 mg/kg feed. For the three experimental treatments, the BD was supplemented with 120 mg Mn/kg either from Mn-sulphate or Mn-chelate of protein hydrolysate (Mn-Pro) or Mn-chelate of glycine hydrate (Mn-Gly). After 8 weeks of dietary treatments the egg production, egg weight, feed intake, and feed efficiency were not affected by dietary treatments. Regardless of the sources, Mn supplementation to feed resulted in significantly decreased percentages of cracked eggs compared to the unsupplemented control group. The thickness, weight, proportion, and index of eggshell were significantly elevated in all groups supplemented with Mn. The intake of Mn-Gly resulted in considerably increased Mn deposition in egg yolk compared to the control eggs. In the control and Mn-sulphate groups yolk malondialdehyde (MDA) started to increase after 20 and 30 days of egg storage respectively, whereas in eggs from hens given organic Mn-sources this parameter was not affected up to 40 days. Although there were no significant differences in MDA values between the treatments until 20 days of storage, the Mn-sulphate group showed significantly higher MDA concentration in yolks compared to the control group after 30 days of storage. These results demonstrate that supplementation of hens&rsquo; diet with Mn has positive effects on eggshell quality. Feed supplementation with Mn from organic sources appears to be more effective in preventing yolk lipid oxidation during cold storage of eggs than that from Mn-sulphate. &nbsp;

Red mite (Dermanyssus gallinae; De Geer, 1778) is currently the most economically deleterious ectoparasite of layer hens in several countries (Chauve, 1998). D. gallinae is an obligatory haematophagous ectoparasite of both domestic and wild birds (Bruneau et al., 2001), only found on the host during darkness when obtaining a blood meal. The remaining part of its lifecycle is spent concealed deep in the house substructure, in cracks and crevices, with control typically implemented via chemical spraying. Mite exposure in laying hens generally results in irritation, restlessness, anaemia, and occasionally death and may subsequently lead to decreased egg production, poor shell integrity, blood staining and egg size reductions (Chauve, 1998; Cosoroaba, 2001). Natural exposure to mite-antigens during feeding activates humoral immunity of the fowl, in the form of immunoglobulin production. However, the magnitude of this serological response over a prolonged infestation period and at different mite population levels is unclear. Therefore the aim of this study was to determine the levels of anti-mite immunoglobulin present in egg yolks of laying hens in flocks infested with differing population levels of red mite over a period of 16 weeks.

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: , , , , , ,
