Field study on the effect of aluminum silicate adsorbent on performance of 51 weeks old broiler breeder chickens

Abstract

In 9 weeks field study, a total of 14100 (Ross broiler breeders) 51 weeks-old chickens fed on the same ration, placed in 2 houses (6600 female + 450 male / house). Birds of house 1 were treated with antimycotoxin adsorbent aluminum silicate (G-V-tox®) 5 kgm/ ton, while those of house 2 were kept as non treated controls. Productivity and reproductivety parameters were calculated for comparison. Treated flock showed improved average egg production (Average 62.2%/week) compared with non treated (Average 61.7%/week), but all still lower than farm stander (Average 76.4%/week). Marked improvement was in the 1 st 3 weeks (51-53) of treatment only. Total 9 weeks production declined was 5.5% and 8.4% in control and silicate treated flock; with weekly average of 0.61, and 0.93; respectively. Control flock was slower in decline of production (0.61%/week) than treated flock (0.93%/week). Average weekly egg production and hatching eggs/ hen in treated flock was lower than standard and higher than non treated. Hatchery parameters of treated were improved in treated at the first 3 weeks post treatment. The fertility was higher in aluminum silicate treated group (77.2%), than the untreated one (72.19%). The hatchability was in silicate treated (63.66%) versus (62.25%) in the untreated control. Culls % in hatched chicks was 1.91% in treated flock and lower than in non treated (2.85%). Difference percentage between fertility and hatchability of G.V. tox treated chickens was (10.84%) higher than untreated control (16%). The number of marketable chicks l100 was also improved in treated than non treated. In conclusion, our field study cleared that administration of Silicate in ration for treatment of broiler breeders resulted in an improved production and hatchery performance as compared with non medicated control. However; it did not restore it to the farm stander. Consequently the results indicated that we still in need for more effective products to be used to control mycotoxins in breeder chicken.

Bio-Efficacy and Thermo-Stability Evaluation of Different Phytase Enzymes in Pelleted and Mash Broiler Diets

“…Our results agreed with Zohair et al (2012) who reported that FI, BWG, FCR and performance index were significantly improved with feeding pellet diet compared to feeding mash diet for broiler chicks. The improvements of pellet in performance have been attributed to decrease feed wastage, reduced selective feeding, destruction of pathogenic organisms, improved palatability (Salari et al 2006), increased nutrient digestibility (Behnke, 1998).…”

“…The present results confirms the recently research of Amer et al, (2015) who found that the chicks fed pellets form has highly significant body weight over the chicks fed mash throughout the 8 weeks. Also, confirms the previous results by Jafarnejad et al, (2010) and Zohair et al (2012) who observed the superiority score of weight for broiler chicks fed pellet diets over those fed mash diet during different stages of fattening periods. These results are not agree with Murakami et al (2008) who reported that quails fed pellet feed presented higher feed intake as compared to mash fed birds.…”

The effects of Papain Crude Extract Addition in Diets on Broilers Production Performances

“…The interaction of mash feed form with each level of papain gave a higher average of carcass percentage than in the form of pellets. The similar effect of feed form has been investigated by Corzo et al(2012) and Cerrate et al (2009) which related to difference size mash compared to pellet form (Abdollahi et al, 2012;Zohair et al, 2012 andDozier et al, 2010). The highest carcass percentage was significant obtained from broilers received the treatment of mash form combined with crude papain 0.05%, while the lowest response of this parameter was revealed in the broilers consumed pellet feed form with crude papain 0.07% addition.…”
