Amino acids in poultry nutrition
Adequate provision of dietary amino acids is required to maintain normal immunocompetence and protection of the host from some diseases in all species (Beski et al. 2015). Therefore, the development of immune function in poultry will be promoted if they receive sufficient amino acids in their diets. The essential amino acids for poultry are arginine, glycine, histidine, leucine, isoleucine, lysine, methionine, cystine, phenylalanine, threonine, tryptophan, and valine. Out of these, the ones critical in practical diets are arginine, lysine, methionine, cystine and tryptophan.
APIs MARKET
The price index of veterinary APIs monitored by China Veterinary Drugs and Feed Trading Centre for four weeks this month was 64.80-65.07-64.90-64.66, indicating that the market is generally stable. Products such as Doxycycline hydrochloride, neomycin sulfate, tilmicosin, enrofloxacin, and florfenicol, etc, have received more attention, while other categories and products have performed stably and are still at the bottom of the market.

INTRODUCTION In line with the tremendous progress that has been made in meat-type duck production, digestibility and balance experiments are necessary to fill the dearth of information on the nutrient digestibility of widely used feedstuffs. Digestibility experiments for the evaluation of nutrient disappearance along the gastrointestinal tract align with the need for precise feed formulation to match animals’ requirements for optimal performance; and minimize the excretion...

The objective of the study was to evaluate tryptophan’s functionally essential role in regulating performance, intestinal inflammation, and disease resistance during a coccidia challenge. A total of 300 two-day-old Cobb 500 broiler chickens (54.29 ± 0.284 g body weight [BW]) were group housed (5 chickens/pen; 10 pens/treatment) in battery brooders and had ad libitum access to a basal diet and water. At 7 d of age, pens were randomly assigned to 1 of 6 levels of dietary...

INTRODUCTION In the modern poultry production system, the first reported chick embryos injection of thiourea was done by Grossowicz in 1946 to observe the effect in hatchling and post-hatch life (1), followed by thyroxin by Balaban and Hill (2). Later, in ovo technique (IOT) was first opted for vaccination against Marek’s disease by Sharma and Burmester (3). Subsequently, the success of in ovo vaccination (IOV) has set forth a paradigm shift in the poultry industry by adapting...

Feather meal (FM) which is a biological bvproduct, has a high crude protein content of about 85%. However, poor digestibility and low nutritional value restrict the utilisation of FM as animal feed, most likely linked to the mechanical stability and proteolytic resistance of keratin (Lasekan et al., 2013). Chemical treatments for improving the nutritional value of feather meal were described recently (Pfeuti et al., 2019a). The current study used a chemical-enzymatic pretreatment...

Introduction In Syria chicken occupies a major place in production and consumption among poultry. It has become the second most popular meat eaten and is most likely to maintain this position. Chicken meat is a good source of protein and many nutrients, and is relatively low in fat, especially if the skin is removed. Chicken meat is also characterized by versatility in menu planning, ease of preparation, consistent quality, and the availability of wide range of pre-packaged, branded,...

An experiment was conducted to assess the potential for guanidinoacetic acid (GAA) to spare dietary energy and influence muscle myopathies when included in broiler diets. A total of 1,056 male Ross 708 broiler chicks were randomly assigned to 48 floor pens with 22 chicks per pen. Broilers were fed one of four experimental diets and reared to 50 days of age. Dietary treatments consisted of a control (T1), T2 (T1 – 110 kcal/kg apparent MEn), T3 (T2 + 0.08% GAA), and T4 (T1 – 55...

Introduction The concept of maintenance has been defined as the state of balance between the intake of nutrients and their inevitable losses (Siqueira et al., 2011; Silva et al., 2014; Soares et al., 2019). That contributes to an understanding of the differences in responses between individuals of a population and enhances the requirements concept. Different methodologies have been developed to estimate nitrogen and amino acid requirements for maintenance (Burnham and Gous, 1992;...

In recent years protein feed ingredients are consistently increasing in cost and protein in poultry diets has become one of the most expensive nutrient. Urbanization is putting pressure to produce more and high quality protein sources in less space. Neutralizing substandard quality feed ingredients with effective tools has also become a new concern. In parallel people are more concerned on impact of animal agriculture on environmental pollution. Hence research has focused in the direction to...

1. Introduction The best strategy to optimize production and reproduction in poultry species while mitigating the harmful effects of environmental conditions is proper nutrition 1,2,3 . One of the pillars of nutrition is the use of amino acids in poultry diets, among which Methionine (Met) represents the first limiting amino acid in broilers. As Bunchasak 4 reported, Met can act as an amino acid in the synthesis of protein and polyamine, a sulfur donor, a...

I. Introduction Wheat and sorghum are the two major feed grains used in Australia for broiler diets; however, wheat is more common and is usually considered better quality than sorghum. The local chicken meat industry may have to increase by 60% to meet demand in 2050 so strategies are needed to promote sustainable chicken-meat production to meet this anticipated demand. Crude protein reductions in broiler diets could be a major factor in the quest for sustainable production....

I. Introduction Guanidino acetic acid (GAA) is a naturally occurring metabolite which is synthesized in the kidney by L-arginine-glycine amidinotransferase (AGAT) using glycine and arginine (Arg) as substrate (Brosnan et al. 2009). Then, GAA is methylated to creatine in the liver using GAA N-methyltransferase (GAMT). Feeding GAA to humans and animals increases creatine in blood and muscle tissues (Ostoic et al. 2013; DeGroot et al. 2018). High creatine in blood has an inhibitory...

APIs MARKET
In August, the veterinary API market remains weak, and the prices of most mainstream varieties continue to go down. Florfenicol, doxycycline, and amoxicillin have stagnant finishing. At the same time, erythromycin thiocyanate, as an intermediate raw material of azithromycin, clarithromycin, roxithromycin, and erythromycin stearate, has reached a historical high, and Tilmicosin price is going up against the trend. Is this the primary sign of rebound expected by the...

I. Introduction Methionine plus Cysteine (Cys) requirement of poultry and swine has been determined using graded levels of DL-Met. Currently, Aviagen recommends 0.95, 0.87, and 0.83% SID Met plus Cys for starter, grower, and finisher phases of Ross 308 broilers (Aviagen, 2019). Cobb recommends 0.88, 0.80, and 0.74% SID Met plus Cys for the respective growth phases (Cobb, 2018). Similarly, Brazilian tables recommend 0.99, 0.97, and 0.91% SID Met plus Cys for broilers starter, grower,...

Description of problem Feed ingredients and feed manufacturing account for 60 to 70% of production costs in an integrated poultry operation. Modern commercial broilers are fed predominately pelleted diets, and researchers have demonstrated how improving pellet quality (PQ), by increasing the percentage of pellets in the diet, further enhances bird performance (Proudfoot and Sefton, 1978; Dozier et al., 2010; Corzo et al., 2011; Lilly et al., 2011; Glover et al., 2016; Lemons and...
