Abstract:
... Synthetic methionine use is currently limited to 1 kg and 1.5 kg per metric tonne (2, 2, and 3 lbs per short ton) of feed for organic laying hens, broilers, and turkeys and other poultry, respectively, in the United States of America. All other synthetic amino acids (AA) have been banned from use in organic poultry diets in this country. It is challenging to provide sufficient methionine (Met) to ...

Abstract:
... The poultry industry is affected by economically important problems such as Newcastle disease (ND). Newcastle disease virus (NDV) belongs to the Paramyxoviridae family and manifests as different strains; lentogenic, mesogenic and velogenic. ND affects the quality of eggs and impairs growth performance of birds. Various efforts have been made to control economic losses due to this disease, includin ...

Abstract:
... Keel bone damage (KBD) is a critical issue facing the contemporary laying hen industry due to the likely pain leading to compromised welfare and reduced productivity. Recent reports suggest that KBD, while highly variable and likely dependent on a host of factors, extends to all housing systems (including traditional battery cages, furnished cages and non-cage systems), genetic lines, and manageme ...

Abstract:
... Chlamydia (C.) psittaci, formerly known as Chlamydophila psittaci infections cause important economical losses to the poultry industry and are a danger to public health. The economic and zoonotic impact of C. psittaci infections in the Western poultry industry is well documented. Less is known on its occurrence in Asia. In the following review we address C. psittaci infections in Chinese poultry i ...

Abstract:
... At the time of writing (and the Journal is always prepared several months before the print copy reaches our readers) I am sat in the cold wet winter of New Zealand. As such I am keeping warm and dry inside with the heating on full. You may think this is just some of my ramblings – $ but it does have a point – one of our papers this issue is a very interesting comparison of welfare between the diff ...

Abstract:
... Intensive poultry production is heavily reliant on electricity for maintaining shed environments as well as in the supply of feed, lighting, the shed environment and water. During the last three decades, the demand and supply gap for electricity has plagued Pakistan. The energy crisis became even worse from 2006-07, with 18 hours rotational load shedding being implemented. During the last decade, ...

Abstract:
... Smallholder farmers in Africa and other developing countries raise village chickens under low input production systems characterised by minimal management and veterinary interventions. However, village chickens have a major contribution to village communities as a source of protein, income and cultural needs. The village chickens are described as nondescript birds that have not been developed as a ...

Abstract:
... Although fertility rates are dependent on both sexes, this characteristic is most often associated with males. For example, the practice of spiking, in which males with undesirable characteristics are replaced with younger males, is often used to improve fertility rates. Dietary restrictions may offset genetic shortcomings to some extent, but nutritional deficiencies due to dietary restrictions ma ...

Abstract:
... The design and management of different housing systems affect poultry welfare. In order to compare wellbeing in different systems, two main indicators of poor welfare have been used in this paper: contact dermatitis for meat birds and mortality for laying hens. The former is important since broilers may suffer from it for much of the later part of their short lives; the latter because it is genera ...

Abstract:
... Nutrients such as minerals and vitamin D have clear roles in skeletal metabolism. Boron (B) has been examined as a possible essential nutrient in the metabolism and utilisation of several micro nutrients and hence could have an influence on bone mineral density and eggshell quality. However, there have been few direct studies to examine the dietary response to B in chicken and layer hen models, al ...

Abstract:
... There are several species of snail with varying nutrient profile. The protein content of snail meal (53-83%) is comparable to or higher than fish meal. Apart from lower methionine, the essential amino acids composition of snail protein is similar to fish meal and better than soybean meal. The fat of snail meal is high in polyunsaturated fatty acids and has a good supply of essential fatty acids (l ...
