Flavonoids and their effect on broiler immunity.

Flavonoids, naturally occurring plant secondary metabolites, are currently under investigation as feed additives in poultry for their antioxidative properties. Antioxidative agents are important for poultry nutrition as they reduce lipid peroxidation, a major concern for the organoleptic characteristics and nutritional value of meat and eggs, and can prolong poultry product shelf life. Apart from potent antioxidants, flavonoids have been shown to possess immunomodulatory and in particular anti-inflammatory properties. Quercetin, a flavonoid belonging to the class of flavonols, is present in several fruits, vegetables and herbs and has been shown to improve oxidative status of broiler meat when added to the birds' feed and was detectable in the plasma and in several tissues of the animals. Quercetin has been shown to act as an anti-inflammatory agent in mice and in humans. So far studies on flavonoids in poultry examine, in addition to meat oxidative status, effects on growth performance and other productive traits, including meat and egg quality parameters. The effect of quercetin on broiler meat quality parameters has been tested before as well. This particular study investigated the possible effects of dietary quercetin on parameters of broiler immune function and status. The Greek researchers examined parameters of cellular and humoral immunity, lymphoid organs size and cellularity and thymus subset composition to determine whether the immunomodulatory properties of quercetin exhibited in other animals are manifested in broilers when it is included in their feed. Animals received or 0.5 gr quercetin per kg feed or 1 gr quercetin per kg feed or a control diet. The researchers did not find differences between dietary treatment groups in cellular immune response or immune status (P>0.05). Interestingly, while total and IgM antibody titres did not differ among treatment groups (P>0.05), IgY antibody titres significantly increased with increasing quercetin supplementation (P-linear<0.05). therefore, dietary quercetin did not compromise any of the immune parameters tested but on the contrary enhanced igy antibody production.> The research paper culled from world poultry.

REARING SMALL RUMINANTS FOR FOOD SECURITY.

Small ruminants  are a viable source of protein,hence are important in the food chain.The rearing process is throughout the year because the period of gestation is 5 months.

The animals are in high demand during festive periods,although they could be found all year round in various food joints because of a sector of the populace that favors these breeds.

 The sheep and goat section is a prominent part of the abattoir operations,and are readily available in meat shops.The raising of the ruminants could be large scale or small scale depending on the financial capacity of the individual.

The breeds of the ruminant selected for the venture are those that can tolerate weather conditions and resistant to diseases.The common breeds include,west African dwarf, Yankasa,Balami,Sokoto red and Maradi.

                  BENEFITS OF RAISING SMALL RUMINANT

. 1) economic value; the animals can be raised,fattened and sold for profit.The kids and lambs can be sorted and reserved to increase herd size .

 2) Provision of much needed protein to promote growth and development of the populace. 

 3)employment opportunity; people who raise these animals actively engage services of herds men,laborers and other assistant to manage the venture.

 4) Its a way to ensure food security.

                  SELECTION OF ANIMALS FOR REARING

. 1) Animals must be sourced from reliable stock,with proven health status.

2 )The animals must be physically fit, and must conform to breed characteristics.

 3)There must be no sign of ill health such as skin diseases,cough,watery/red eyes and diarrhea.

 4)The animals must be weighty, not obese and young animals are to sourced.

 5)Dont buy during festive peaks as the prices will be astronomical thus increasing cost of production.
The animals are raised in clean,dry and ventilated housing.The housing preference depends on the keeper. The animals might be housed in groups in various housing,or they are left to graze round the compound and are provided with shelter on a side in the farm.

The advantage of housing in groups and feeding far out ways other methods.The house should be on well drained land to prevent flooding /wetness which will make the animals prone to foot rot.

The house is usually made of wood and covered with sheets,,the floor is made of roughened concrete with slants so that the animal wont slip and washing of pen is easy

. The feeding accounts for 65-70% of production,and the main source is grass of various types that are chopped and provided.

The animals to be fattened need to be provided with other feed sources so that they mature fast.These feed sources are commercial feed formulated for growth and maintenance. Water is essential for the ruminants,thus cool,clean water should be provided everyday. Mineral supplements are provided in form of salt licks.

                    HEALTH MANAGEMENT.

 1)Quarantine new stock,before release to the farm.

 2)stabilize new stock, by deworing and placing on vitamins

 3)Eradicate ectoparasites,by using appropriate chemicals for tick bath.
