Effect of an Aqueous Nanosuspension of Clay Minerals on the Performance, Carcass Characteristics and Internal Organs of Broilers

Abstract

improved nutrition. Consumers are moving from the consumption of whole chickens toward the consumption of cuts and further processed broiler products [1]. The increase in further processing has increased concerns about the quality and control of factors influencing broiler performance, carcass cuts and meat quality.The growth and development of muscles consists of hyperplasia, where the total number of myofibers increases and hypertrophy, which leads to the increased volume of the individual my fibers [2,3].The experimental biology symposium entitled "Nanotechnology Research: Applications in Nutritional Sciences" was organized to highlight the emerging applications of nanotechnology in food and nutrition sciences and to suggest ways of further integrating of these emerging technologies with nutrition research. Nanotechnology has the potential to revolutionize agriculture, veterinary medicine, animal health and other areas of animal production [4]. Moreover reported that nanotechnology can increase the cost-effectiveness of poultry and meat products with natural properties [5]. In the area of nutrition it is possible to apply nanotechnology in several ways such as obtaining information about a nutrient, avoiding nutrient degradation and obtaining greater availability [6]. Minerals are one of the most widelyused supplements in animal nutrition [7]. Developed highly available nanoparticles of ferric phosphate, demonstrating that the nanoscale of this nutrient increased its nutritional value. However, in research on the mineral nutrition of poultry, several minerals are important. Therefore, this study focuses on the effect of nanotechnology on clay minerals obtained from different areas of Jordan as an inexpensive source of several minerals, and examines their effect on broiler growth performance, carcass characteristics and internal organs measurements compared with or without antibiotics. Materials and MethodsExperimental birds and rearing conditions: A total of 640 one-dayold unsexed Lohman broiler chicks were purchased from a commercial hatchery. The average body weight of the chicks was 40 g. The chicks were randomly allocated into 32 pens (1.15 m × 2.10 m) in an open-sided house (8 treatments × 4 replicates × 20 chicks). Chicks were vaccinated against the Newcastle (ND) HB1 strain and the Infectious Bronchitis (IB) IB120 strains at 7 days of age, the La Sota strain at 21-days of age and against Infectious Bursal Disease (IBD) at 13-days of age. Feed and water were offered ad-libitum. The treatments used are listed in table 1. The experimental diets were given once each week or once every two weeks and the other days the chicks were fed the basal rations without any supplementations.Experimental rations: Chicks were fed a starter ration from one to 21-days of age and a finisher ration from 22 to 36-days of age (Table 2).All rations were formulated to meet the requirements recommended by the strain guide. A randomized sample from each starter and finisher diets were collected for proximate analysis by the proce...

Effect of Different Levels of Aqueous Suspension of Bentonite Nanoparticles on Performance and Carcass Characteristics of Broiler Chickens

“…This would be also attributed to the ability of nanoparticles to bind with the pathogenic microbes that may be established in the gut of broiler chickens. This result was in agreement with Al-Beitawi et al, (2017a) who reported that the use of the aqueous nanosuspension of clay minerals significantly improved the FCR of broiler chickens. Also, Al-Beitawi et al, (2017b) observed an improvement in FCR when broilers were fed 2% nano clay minerals compared to control groups.…”

“…However, 2% of nano clay minerals offered once a week only increased spleen percentage compared to other dietary treatments. Al-Beitawi et al, (2017a) found that the values of the dressing, breasts, thighs, and drumsticks significantly increased in birds receiving the nanosuspensions of clay minerals (2%). The dressing and cuts percentages were 73.45, 28.25, 12.88, and 10.71 for the dressing, breast, thigh, and drumstick, respectively.…”

“…Nanoclay minerals have been a unique additive possessing sizeable surface area, higher porosity, strong cation exchange activities, and more active sites (Al-Beitawi et al, 2017a). In addition, nano clay minerals at particular levels would improve the growth performance of broiler chickens (Elshuraydeh et al, 2014).…”

“…Clay minerals are used as additives in ruminant feed due to their ability to reduce feed contamination with mycotoxins, which is especially crucial as changes in climate can lead to increased mycotoxin spread in different regions of the world ]4[. The chemical properties of clay minerals, containing elements like Na, K, Mg, Fe, and Ca, may contribute to improving body weight and feed conversion rate [5]. Clay minerals, particularly those with aluminum silicate, are utilized in ruminant feeding to enhance the digestion coefficient of nutrients, weight gain, and feed intake [6,7].…”
