As highlighted in latest scientific research, keel bone damages may end up in important welfare challenges for laying hens. On account of its anatomical place, keel bone is vulnerable to deformities, particularly in fashionable layers with smaller pectoralis muscle. As much as 90% of laying hens housed in aviary programs are affected by keel bone fractures, that are prone to trigger ache and struggling. These days, fashionable genetics are extremely environment friendly. Hens producing as much as 500 eggs per cycle (prolonged as much as 100 weeks of age) have excessive calcium (Ca) necessities. This laying productiveness can thus negatively influence keel bone well being. It’s value noting that eggshell formation depends on Ca supply from the skeleton, the place 20 to 40% is saved after being equipped via feed. Keel bone damages contains each fractures and deviations. Fractures typically end result from a collision with housing gear, similar to perches, leading to a partial or massive fracture with bone displacement. These fractures are strongly related to ache and a drop in egg manufacturing. However, deviations are likely to develop regularly because of fixed strain on the keel bone as a result of prolonged perching behaviour and/or osteoporosis. Making certain good skeletal growth and managing Ca metabolism throughout the laying interval are essential to maintain hen welfare and financial efficiency. Some correlation between lowered egg high quality and susceptibility to keel bone fractures has been established. Moreover, muscle growth and protein retention are essential in sustaining the persistency of the laying curve.
Pectoralis muscle growth and keel bone integrity are subsequently key predictors of laying efficiency and persistency. Lallemand has developed a brand new software of ultrasonography to research these parameters in a non-invasive means and objectively reveal the advantages of a probiotic, Pediococcus acidilactici CNCM I-4622 (BACTOCELL), on hen pectoralis muscle and bone growth whereas supporting welfare.
Bactocell advantages on laying efficiency and egg high quality
Over the previous 20 years, using this probiotic devoted to monogastric animals has been extensively documented with greater than 100 scientific publications. This lactic acid micro organism was particularly chosen for its capability to completely produce excessive ranges of L-lactic acid (a supply of vitality for birds).
Improved laying charge and persistency in addition to higher eggshell high quality have been noticed following supplementation with this probiotic. A meta-analysis was lately carried out to evaluate the influence of BACTOCELL supplemented on the business dose (1×109 CFU/kg of feed) on laying efficiency and egg high quality. A complete of 62 research have been compiled, together with each educational and area trials originating from 25 completely different nations, utilizing completely different however related genetic strains. BACTOCELL supplementation considerably improved laying charge by 2.7% (P<0.001) and enhanced FCR by 3.1% (P<0.001). The common egg weight was 0.6 g increased for BACTOCELL-supplemented hens (P<0.001), resulting in a major improve of exported egg mass (CONTROL: 0.361 vs BACTOCELL: 0.372 kg/ hen/week, P<0.001). As well as, the incidence of damaged or downgraded eggs was considerably diminished by 21% (P=0.015). Moreover, using this lactic acid micro organism diminished mortality by 33% (CONTROL: 4.6 vs BACTOCELL: 3.1 %, P=0.005). Total, this meta-analysis highlighted the advantages of utilizing BACTOCELL to enhance the efficiency of laying hens, no matter housing system or manufacturing part.
Bactocell advantages on pectoralis muscle growth
Constant outcomes exhibiting a major improve of pectoralis muscle thickness have been noticed when supplementing completely different poultry species (pullets, layers, broilers) with this particular probiotic over completely different intervals of time (Desk 1).
As talked about in Desk 1 and detailed by Determine 2, a latest area trial carried out in laying hens confirmed a major enchancment of pectoralis muscle thickness by each the center and the tip of the laying cycle when layers have been supplemented with BACTOCELL (+40% and +28% vs management group, P<0.001).
Bactocell advantages on bone metabolism
Bone resistance and mineralization are important to make sure optimum eggshell high quality.
A trial carried out on 50-week-old layers supplemented with BACTOCELL for 14 weeks confirmed an enchancment of each Ca and phosphorus (P) retention (+4.2 % and +4.1%, respectively, P<0.05) and a rise of blood Ca and P focus (+5% and +12%, respectively, P<0.05) in comparison with management hens. Furthermore, increased bone Ca and P concentrations have been noticed within the BACTOCELL group (+4% and +7%, respectively, P <0.05). These outcomes might be translated into enhanced bone hardness (+19%, P<0.1) and bone cohesiveness (+43%, P<0.05). Blood calcitriol, which is the energetic type of vitamin D (often known as 1,25-dihydroxycholecalciferol, 1,25(OH)2D3, a Ca absorption promoter), elevated by 83% (P<0.05) with BACTOCELL supplementation. Blood osteocalcin focus was additionally improved by 2.75% with the probiotic (CONTROL: 278.55 vs BACTOCELL: 286.20 ng/mL, P<0.1). Osteocalcin is a key hormone in bone metabolism. It’s synthesized by osteoblasts and used as a biomarker of osteoblast exercise and bone formation.
Moreover, in a latest area trial (inner knowledge, Italy, 2024), laying hens supplemented with BACTOCELL confirmed fewer keel bone deviations (10% vs 20% in management group) and keel bone fractures (40% vs 55% in management group). Extra intact keel bone have been noticed within the BACTOCELL group (50% vs 15% in management group). Some laying hens introduced each keel bone deviation and fracture (10%), however all of them have been within the management group. When some keel bone deviation and/or fracture have been noticed, their severity was diminished within the probiotic-supplemented group (Determine 3).
Utilizing ultrasonography to guage breast muscle growth and bone mineralization can stop the routine use of invasive measurements involving the loss of life of birds, particularly within the present context of extending hen life cycles for financial, societal and environmental issues. Ultrasonography can subsequently be thought-about as a useful diagnostic device to foretell laying efficiency and egg high quality whereas supporting animal welfare. This technique can be utilized to objectively reveal the advantages of the probiotic Pediococcus acidilactici CNCM I-4622 (BACTOCELL) on each muscle tissues and skeleton growth, proving BACTOCELL to be a useful dietary technique to safeguard laying efficiency and egg high quality.
