Bacterial chondronecrosis with osteomyelitis (BCO) is an infective leg condition that results in lameness, affecting meat chickens internationally. BCO can be induced using mechanical challenges such as wire ramps (Wideman 2016). Based on a study wherein perches had a negative impact on bird latency to lie (LTL) at 42 days (d) old (Phibbs et al. 2020) perches may be a mechanical challenge to birds also, reducing their leg health in a similar way to Wideman’s ramps. This study compared...

It is widely accepted that the absence of suffering no longer defines animal welfare and that positive affective experiences are important (Mellor 2015). However, there are few valid and reliable tools available to comprehensively...

I. INTRODUCTION Heavily driven by public perception and large supermarket monopolies, welfare is of major concern for the poultry industry. The past few decades have seen development of poultry practices with a heavy focus on the welfare of poultry. There have been huge changes implemented to accommodate improvements in welfare, particularly in the layer industry. There are now a number of production systems...

Free-range layer pullets are typically reared indoors within Australia, but adult layers go outdoors which might cause poorer adaptation due to the mismatch between rearing and laying environments. Indoor enrichments may optimise physical development of pullets and subsequent welfare as adult free-range hens (Campbell et al., 2019). In the outdoor environment, hens may have greater opportunities for exercise and natural behaviours which might contribute to improved physical health and...

I. INTRODUCTION Maintaining vegetation on free range farms with fixed ranges is a significant issue (Singh et al., 2017). Nonetheless, free range accreditation programs stipulate palatable vegetation to be available on the range at all times (RSPCA 2015). This is more problematic to achieve during dry seasonal conditions and drought, which are common features of the Australian climate. ...

Free-range layer systems are increasing globally but range use can be low, particularly when birds are first provided outdoor access. It is recommended to match the rearing system with the layer system for optimal bird welfare (Janczak and Riber, 2015). However, within Australia, pullets destined for free-range systems are typically reared indoors which may hinder their adaptability to the outdoor environment as adults. Rearing enrichments may optimise behavioural development and better...

1. INTRODUCTION Consumer demands and the pressure of supermarket chains are changing rapidly the way eggs are produced. Enriched cages are not considered a sound alternative to improve animal welfare standards in the developed countries. Consequently, the industry is moving hens from battery cages towards alternative systems, such as deep litter and aviary barns, with or without access to an outdoor area. In addition, organic production with non-beak trimmed hens, under...

Coccidiosis is a disease of the intestinal lining, produced by the invasion of the mucosal cells by a very prolific protozoan parasite of the genus Eimeria. This invasion results not only in the interruption of feeding and digestive processes involved in nutrient absorption but can also cause intestinal inflammation leading to dehydration, blood loss, loss of skin pigmentation, and increased susceptibility to secondary bacterial infections like necrotic enteritis and...

Introduction In practice, an optimisation program is used to formulate commercial diets to meet the minimum nutrient constraints in order to minimise feed costs. With phytase, potentially unjustifiable high contributions will result in reduction of safety margins or even lead to nutrient and energy deficiencies with a negative impact on animal performance. When applying values, it is important to understand that it is not possible to compare matrices from different phytases...

In the past few decades in South East Asia (SEA), with a moderate increase in the layer hen population, egg production rate and lifespan have greatly improved. However, when compared with the global egg production per capita (less than 7 vs. more than 10), there is still a significant opportunity to further increase egg production in this area. In SEA, the top challenges for the layer industry are egg quality and egg production rate, especially for old flocks. In old layers, especially after...

I. INTRODUCTION Calcium and phosphorus are two minerals of great concern to poultry nutritionists as a result of the relatively large quantities needed in the diet, and the adverse effects on bone formation, shell quality, and overall performance when inadequate amounts of these minerals are supplied. It is further difficult to discuss calcium supply in poultry diets without referring to phosphorus, since the...

I. INTRODUCTION Commercial laying hens have been successfully selected for increasing production cycle lengths. Rather than being depopulated at 60 to 70 weeks of age, or being moulted to allow for additional production cycles, the egg industry has moved towards cycle lengths of 80 weeks or even longer. Selection for increased persistency of production and livability, skeletal health, and a slow rate of increase...

Dr. Charles Ibe, I agree about the biosecurity. The use of agents that induce lysis of sporulated oocysts reduces the number of resistant ones and increases the efficacy of both vaccines and coccidiostatics. High humidity, as well as low humidity, stops the sporulation process. ...

INTRODUCTION The Food and Agriculture Organization (FAO) forecasts that the human population will increase by 30% by 2050 (FAO, 2019) with corresponding increase in demand for food. Animal protein, the largest component of human food is entirely dependent on livestock production channels as its source. Over 70% of the cost of livestock production is feed, and the second largest component and cost of feed is the crude protein, a segment that has been challenged for its...

Introduction Modern meat chicken breeding stock have been selected for extremely efficient conversion of feed into protein and rapid growth. As a result, it has become increasingly more difficult to rear pullets and breeders to achieve the healthy chick numbers needed to supply the ever-expanding poultry meat market. There are many factors involved in producing a healthy pullet and breeder chicken. These include; housing, lighting, temperature and air control, health,...

Method details Salmonella spp. cause fowl typhoid and pullorum diseases in poultry and are responsible for nontyphoidal Salmonella infection in humans. Prevention of Salmonella infection in chicken flocks is an important step in reducing salmonellosis outbreaks in humans. Vaccination with live attenuated vaccine of certain strains such as e.g. S. Enteritidis, S. Typhimurium and S. Gallinarum has been commonly used in the field to prevent the disease, and proven to be useful to...

INTRODUCTION The quality of egg depends on physical make-up and chemical composition of its constituent namely egg shell, albumen and yolk. Chemical compositions are important in egg product industry as the demand of liquid eggs, frozen eggs, egg powder and yolk oil increases (Song et al., 2002). However; significant percent loss occurs in albumen and yolk chemical composition and pH by long storage periods (Bufano, 2000). Environmental factors such as temperature, humidity, and...
