Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
Alternative feed ingredients have proved valuable in supporting the performance of livestock and poultry at low cost (Babatunde and Oluyemi, 2000). Kolanut shell can be substituted for 60% of the maize in layer mash (Olubamiwa et al., 2000), for 20% of the maize in broiler diets (Hamzat and Babatunde, 2001) and for 50% of the maize in rabbit diets (Babatunde et al., 2001). This study was designed to determine the optimal replacement level of kolanut shell meal...

Rickets can occur in young birds due to insufficient Vitamin D 3 , calcium and/or phosphorus. Commercial feeds and supplements provide these nutrients, but if they are over-diluted, the birds will not get enough. Birds can synthesize their own Vitamin D, to a certain extent, with exposure to sunlight. A deficiency of any of these nutrients can also lead to problems with egg-laying birds. Egg production may be reduced...

SUMMARY A total number of 240 laying hens and 24 cocks of Silver Montazah strain at 40 weeks of age were randomly divided into 12 groups (20 hens and 2 cocks / each treatment group). Birds in all treatments were nearly similar in the average initial body weights and average daily egg production. A 4 x 3 factorial design experiment was performed including four levels of supplemented lead (0. 250,500 and 1000 mg/kg diet)...

Broiler strains have different nutritional requirements depending on their specific growth performance. Because their genetic evolution might be different, Adisseo looked into the effectiveness of carbohydrase enzymes in the different genotypes. In two different trials carried out at the University of Sao Paulo, in Brazil, we demonstrated that Rovabio ® ,...

Intestinal health and immunity is the most critical system to manage in order to optimize performance in today´s commercial poultry. The development and maturation of the GI tract can be influenced by any number of factors involving genetics, nutritional, management, and health issues. The maintenance of a normal, functioning intestinal tract during grow-out is also vital to minimize the effects of enteric...

Belgium's Ghent University launched a new web application allowing livestock producers and veterinarians to measure levels of antibiotic usage on the farms - and how to compare this to peers, Flemish agricultural website Vilt reports. The new web application, called ABcheck, will contain a wide range of background information about antibiotic use and antibioitic resistance in animals.

When nutritionists formulate diets, reference values are typically used to determine the nutritive content of the ingredients and the resultant diet. However, different corn hybrids have different chemical and physical traits which change the nutritive value of the corn relative to reference values. Using different corn hybrids as dietary ingredients can affect the nutritive value of the diet, which, in turn, may affect broiler-chicken growth performance. In this study, the effects of corn...

Introduction and objective The ban or more limited utilization of antibiotics growth promoters in many countries has reduced the tools to control gut microflora. In this context, a synthetic ion exchanged clay under a patented process (B-Safe), was developed and is proposed as an alternative to antibiotics to help in the gut microflora management. In vitro and in vivo trials were...

Introduction: Yellow dent corn yields have been greatly improved by plant breeders since the 1950s. Unfortunately, as yields heightened and other agronomic traits were improved nutritional quality declined and variability increased. A ready however, new generations of “value enhanced’’ corn with multiple advantageous traits are coming into the market. (J.C. Weigel, 1999). In these new, nutrient dense types of corn,...

Rovabio ® , the versatile enzyme from Adisseo, has a proven efficacy on wheat and corn distillers dried grain with solubles (DDGS) on broilers. We evaluate that the metabolizable energy uplift with Rovabio ® Excel is about 5.5 % for corn DDGS and 7.5% for wheat DDGS.
The significant levels of cellulase and xylanase in Rovabio ® allow for breakdown of the increased...

Poultry diets must be formulated to provide all of the bird's nutrient requirements if optimum growth and production is to be achieved. There are six classes of nutrients: Carbohydrates - the major source of energy for poultry. Most of the carbohydrate in poultry diets is provided by cereal grains. Fats - provide energy and essential fatty acids that are required for some body...

Antibiotic growth promoters (AGPs) have been an integral part of the poultry feed industry for more than fifty years. However, a search for the alternatives to the AGPs has been initiated since their prolonged use has precipitated some problems such as development of resistant strains within groups of primary pathogens or opportunistic bacteria and break down of the symbiosis between the animal and desirable flora. The search is therefore on for an economically...

Abstract Twenty nine cockerels were used to investigate the effect of cassava peel meal on the haematology. The birds were assigned to 3 treatments namely D1, D2 and D3. D1 had 9 birds and served as control. D2 and D3 which contained 20% and 30% CPM respectively had 10 birds each. Statistical analysis of the haematological parameters showed significant differences (P<0.5) between...

Gastrointestinal diseases pose a serious threat to commercial poultry production. Infections with pathogenic bacteria and their subsequent translocation to other organs and tissues, cause deterioration of feed conversion, increase mortality and reduce productivity. A number of studies have shown enhanced nutritional and growth parameters in poultry, using organic acids. However, most acids are corrosive, with negative impacts on work safety as well as on the feed...
