Growth Performance and Health Status of Broiler Chickens Treated with Natural Kaolin

The The use of Kaolin as an inert ingredient in feed has been very common in the poultry industry. The present study aimed to investigate the effects of different inclusion rates of Egyptian kaolinite in broiler chickens’ diet on growth performance, immune response, some blood serum changes, and bone development. A total of 240 unsexed one-day-old Avian 48 breed chickens were used in this experiment. The chickens were individually weighed and randomly allotted into 3 equal groups (80 chickens per each group) and each group was subdivided into 4 replicates (20 chickens per replicate), which received one of the three experimental diets (0.0, 0.5, and 1.0% kaolin for groups 1, 2, and 3, respectively) during the experimental period (6 weeks). The obtained data revealed that kaolin addition at the dose of 0.5 or 1.0% in broiler chickens' diet insignificantly increased final body weight by 4.5% and 4.4%, respectively. On the other hand, it respectively decreased total feed intake by 1.0% and 1.8% and significantly improved the average feed conversion ratio and efficiency of energy utilization throughout the whole experimental period compared to the control. Moreover, kaolin addition had no adverse effect on the serum lipid profile and improved antioxidative activity through reduced nitric oxide and lipid peroxidase (malondialdehyde) concentrations or increased the activities of Glutathione peroxide, Catalase, and Superoxide dismutases in serum or liver tissues. Lysosomal and bactericidal activities were increased with kaolin addition at both levels in the broiler chickens’ diets. The present results suggested that the broiler chickens’ fed with kaolin-enriched diets improved growth, antioxidant activity, bone mineralization, and immune response.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

The aim of the present study was to evaluate the effects of feed particle size and flooring designs on organ traits, performance and pododermatitis in broilers. A total of 480 broilers (Ross 308) of both sexes were randomly assigned to two feeding groups (finely or coarsely ground pelleted diets; with addition of 5% to 10% intact wheat in coarsely diets) and four different housing systems (litter; litter with floor heating; partially or fully slatted floor) with three subgroups each. A coarse diet increased the final gizzard and pancreas weights (p < 0.001) while decreasing the risk of Isthmus gastrici dilatation compared to a fine diet (p < 0.001). Broilers fed a coarse diet displayed an increased final body weight (p = 0.023) and led to a favourable feed conversion ratio. Final body weight was the highest (p < 0.001) for birds housed on partially or fully slatted floor. Housing birds on litter with floor heating showed the lowest pododermatitis scoring (p < 0.001). It seems to be favourable to use coarse diets for organ development, whereas slatted floors seem to foster enlargement of the Isthmus gastrici. Increasing growth performance was possible both when using coarse diets or slatted floors.

A feeding trial was conducted to determine the growth performance and carcass characteristics of Japanese quails fed diets containing sorghum. A total of ninety of one-week old Japanese quail chicks were used for the experiment. Five diets were formulated in which sorghum was included at graded levels 0, 15, 30, 45 and 60% dietary levels designated as treatment 1, 2, 3, 4 and 5 respectively. The experimental period was five weeks when the birds reach six weeks of age. The results of the growth performance showed significant differences (P<0.05) in the final body weight (161.70 – 180.10 g) and daily feed intake (21.34–25.12 g). Significant (P<0.05) differences was also observed in all carcass parameters measured except for dressing percentage. Liver weight and large intestine with T5 (65% total replacement) recorded the highest means value of 6.00 g and 6.66 g. Non-significant high values of feed conversion ratio were also obtained among the treatments. Treatment 1 (0%) and Treatment 5 (60%) showed better results in all parameters measured compared to other treatments. In conclusions, sorghum grain can play a significant role in formulating quail feed and can completely (60%) be used to replace maize without affecting the performance and carcass yield of the quails.

This study was conducted in order to investigate the effects of a multivitamin complex and probiotic blend in drinking water before and after vaccination on growth performance, carcass traits, blood biochemical parameters and humoral immune response of broiler chickens. A total of 150 one day-old male broiler chicks (Ross 308) were randomly allocated to five treatment groups, with three replicates (10 birds per replicate) in a completely randomized design. Experimental treatments consisted of: 1) a basal diet and drinking water without any additives as control (C); 2) C + drinking water + multivitamin complex from 2 days before vaccination until 3 days after vaccination; 3) C + drinking water + multivitamin complex for 3 days after vaccination; 4) C + drinking water + probiotic blend from 2 days before vaccination until 3 days after vaccination; and 5) C + drinking water + probiotic blend for 3 days after vaccination. In the whole experimental period, feed intake, body and thigh weight and abdominal fat were significantly affected (P<0.05) by dietary treatments. On the contrary, no significant effect was observed on carcass characteristics, feed conversion ratio, blood parameters, antibody production against SRBC and IgG. The titer of IgM was higher in treatment (2) than other treatments at 28 d of age (P<0.05). In conclusion, a multivitamin complex supplied in drinking water for 2 days before vaccination till 3 days after vaccination is enable to improve broiler performance and immunity.

Turmeric (Curcuma longa) is an extensively used spice, food preservative and coloring material that has biological actions and medicinal applications. Tumeric, when used as an additive could enhance the performance of broiler chickens in Nigeria. The aim of the present study was to assess the growth performance and haematological characteristics of starter broiler chicken fed diets supplemented with processed turmeric) meal (TM). Ninetysix, two weeks old unsexed “Agri-tech” broiler birds were randomly distributed in a completely randomized design (CRD) into four treatments, comprising of twenty four birds each, with three replicates per treatment (having 8 birds per replicate). The processed turmeric was included at the rate of 0%, 0.5%, 1.0% and 1.5% respectively. Feed and water were given without restriction. Supplementation of processed turmeric meal in the diet of starter broilers significantly (p<0.05) influenced the final body weight, average daily feed intake, average daily weight gain and feed conversion ratio. The treatment groups containing processed turmeric meal had poor performance in all parameters studied when compared to that of the control. Mean values of all haematological parameters evaluated namely; packed cell volume (PCV), haemoglobin (Hb), red blood cell (RBC) and white blood cell (WBC) differed significantly (p<0.05) between the control and the turmeric treated groups, however all the values obtained were within the recommended standard range of values for broiler. It was concluded that processed turmeric meal can be added to the diets of starter broilers up to the level of 1.5% and also can be safely used as a phyto-additive in starter broiler chickens, preferably in their feed.

Dietary Treatments

This study was conducted to determine the growth performance and profitability of broilers chicken with vermi meal supplementation under a total confinement management system. A total of 60 broiler chickens were randomly distributed to four dietary treatments: T1= commercial feed (CF), T2= CF+2% vermi meal (VM), T3= CF+3% VM, T4= CF+5% VM inclusion in a completely randomized design. Feed conversion ratio was not significantly influenced by VM supplementation. However, the highest feed intake was recorded in broilers fed CF supplemented with 2% VM (T2) while control broilers fed only CF (T1) had the lowest feed consumption. Broiler chickens fed CF supplemented with 2% VM (T2) were recorded with the highest values of final body weight and weight gain compared to T1 group and T4 group, respectively. However, broiler in T2 group had similar values of body weights and weight gains compared to T3. Consequently, 2% level of VM had an optimum result in final weight, weight gain, and feed consumption, while comparable to the other treatments in water consumption, feed conversion ratio, dressing percentage, and carcass weight. Cost and return analysis of the dietary treatments with VM showed a negative effect, since the higher concentration of VM supplementation had the higher cost in production, due to the expensive price of imported vermin or earthworm meal.

Sawdust and wood shavings are the major industrial waste from wood and its related industries. Steam-explosion treatment enhances the utilizable fiber fraction in pinewood particles. This study investigated the effects of adding up to 2% of steam-exploded pine particles (SPPs) in diets on the growth performance and cecal microbiome of broilers. On the 8th day of age, 216 Ross 308 broilers were allocated to three treatments of 72 broilers/group, with 12 replicates of 6 broilers each, to receive 0%, 1%, and 2% SPPs in their diets. The experimental period was from the 8th to 28th day of age. The parameters recorded included growth performance, relative organ weight (duodenum, jejunum, ileum, liver, and spleen), absolute organ length (duodenum, jejunum, ileum, and cecum), blood biochemicals (glucose, total protein, triglyceride, and cholesterol), and microbial analysis from cecum samples. Growth performance parameters, such as the average daily gain, average feed intake, feed conversion ratio, organ weight, length, and blood biochemical parameters, were not influenced by dietary supplementation of SPP. The abundance of fibrolytic bacterial genera, such as Mediterraneibacter and Anaerobutyricum, was increased in 2% SPP-supplemented chickens. An unknown bacterial genus was also enhanced in 2% SPP-supplemented diets related to the family of fiber-degrading bacteria and needs further investigation. In conclusion, 2% SPP can be supplemented in chicken diets as a source of fiber from wood industry-related waste without having any harmful effects on broiler chickens.

The aim of this study was to compare selected growth performance parameters and slaughter characteristics in broiler chickens fed diets with a different content of full-fat Hermetia illucens L. (HI) larvae meal. The experiment was performed on 384 male broiler chickens (Ross 308) reared to 42 d of age and assigned to four dietary treatments (HI0—control diet and diets where soybean meal protein (SBM) was replaced with HI protein in 50%, 75% and 100%, respectively). The final body weights of chickens were as follows: 3010.0 g (HI0), 2650.0 g (HI50), 2590.0 g (HI75) and 2375.0 g (H100, p < 0.05). The carcasses of chickens from the experimental groups contained less meat and more abdominal fat. The feed conversion ratio for the entire experimental period was similar in groups HI0, HI50 and HI75 and more desirable than in group HI100 (p < 0.05). The meat of broiler chickens from groups HI75 and HI100 was characterized by significantly (p < 0.05) lower juiciness and taste intensity than the meat of birds from groups HI0 and HI50. The replacement of SBM protein with full-fat HI larvae meal in broiler diets exceeding 50% significantly compromised the growth performance of birds and the carcass and meat quality.

One hundred and fifty (150)day-old Abor acre broiler chicks were used for this experiment toassess growth performance and carcass characteristics of broilers fed processed roselle (Hibiscus sabdariffa) seed meal were investigated. The birds were randomly assigned to five dietary treatments with three replicates (ten chicks per replicate)each in a completely randomized design (CRD). In the feeding trial, raw roselle seed meal (R RSM), roasted roselle seed meal (R RSM), boiled roselle seed meal (BRSM) and soaked roselle seed meal (SRSM) were incorporated as part replacement for groundnut cake at 50% level of inclusion.Proximate composition of the processed test ingredients and the results showed that there were no significant (P>0.05) differences among the treatment means. Raw roselle seed meal (RaRSM) gave the least crude protein while the highest was recorded in boiled roselle seed meal (BRSM). Birds fed diet without roselle seed meal inclusion (control diet) had the best final body weight and feed conversion ratio but not significantly (P>0.05) different from other treatments.Birds in treatments 2 and 4 (RaRSMand BRSM) had the least survival rate (96.67%)while the rest treatments had 100%. Cut-up parts showed no significant (P>0.05) differences exceptfor the wings of the bird fed roasted roselle seedmeal was significantly (P<0.05) different and higher than those fed control, raw, boiled and soaked roselle seed meal (10.87, 7.52, 9.85 and 9.46%, respectively). Results from visceral organs showed no significant (P>0.05) differencesexceptproventriculus which exhibited significant (P<0.05) differences among the treatment means. Proventriculus of bird fed roasted roselle seedmeal (R RSM)was highest (0.80%)while those fed raw roselle seedmeal (R RSM) gave the least (0.50%). This study however, revealed that using processed (roasted, boiled and soaked) roselle (Hibiscus sabdariffa) seed meal as part replacement for groundnut cake has no deleterious effects onthe broilerchickens.

Viral Shedding

This study was carried out to evaluate the effect of different Low Pathogenic Avian Influenza (LPAI) H9N2 vaccines containing different virus strains (vaccine A, vaccine B, and vaccine C) on the productivity and immunity of 10 days-old broiler chickens. Two hundred day-old Cobb broiler chicks were divided into eight groups, 25 chicks in each group. Six groups were vaccinated with Vaccine A, Vaccine B, and Vaccine C (2 groups/each vaccine) at 10 day-old, respectively. Chickens of groups 7 and 8 were kept as control groups. One group from each vaccine was challenged at 28 days old with 106 EID50/0.2ml of A/chicken/Morocco/SF1/2016 (H9N2) virus via the oculonasal route. The remaining groups were kept unchallenged to evaluate the immune response. Chicks were sampled each week individually until 42 days old for zootechnical traits and serological evaluation. Two necropsies were done at 5 and 10 days post-challenge (DPC). Lungs and tracheas were collected for histopathology, and the virus shedding was monitored at 5, 7, 9, and 11 DPC by real-time RT-PCR. Results indicated that vaccine B provides significantly better growth performances (P < 0.05), final body weight gain (2689.6 g ± 73.2), and feed conversion ratio (2.10 ± 0.06) when compared to other vaccinated groups. During the challenge (28th -35th days), vaccine B showed a significant increase in antibody titer (26180 ± 1129.1) than other vaccines. In contrast, the vaccine C group had a similar immune response to that of the control group. Both vaccines A and B were able to stop virus shedding by 11 DPC with higher mean Cq values. However, the vaccine C group continued to shed the virus until 11 DPC. Pathological examination of challenged birds revealed lesions predominantly in the respiratory tract. At 5 DPC, fibrinous sinusitis, tracheitis with fibrin plug, pneumonia, and fibrinous airsacculitis were observed. By 10 DPC, the fibrinous inflammation inceased, and only congestion in the trachea, lungs, and sinuses with thickening of air sacs were observed. Histopathology revealed lymphoplasmacytic tracheitis and congestive pneumonia. Scoring of lesions generally revealed more severe lesions at 5 DPC. Statistical analysis of both macroscopic and microscopic scores showed no significant differences between groups in both necropsies. In conclusion, vaccine B has significantly better seroconversion, better growth performance parameters, and a relatively early stop of viral shedding compared to other vaccines.
