ABSTRACT

A study on effects of fermentated casava meal with Amylomyces rouxii supplementation in broilers diets was assigned using a completely random design (CRD).The experiment composed of 5 treatments with 4 replication each. Ten chicks of both sexes at birth were allocated in each replication on the total of 200 chicks. Diet in control treatment contained 0% of fermented cassava meal (FCM),diet in treatment 2, 3, 4 and 5 composed of 5, 10, 15 and 20% FCM. The results showed that increasing levels of fermented cassava meal (FCM) significantly reduced (P < 0.05) performance of broilers during 4 - 6 weeks of age as compared to the control group. During 0-3 weeks of age,production performances of broiler among treatments were not significantly different. Levels of FCM in this study can be used to supplement in broiler diets 0 - 3 weeks of age with no effect on the performance. However, the optimum levels of FCM in broilers diets should be 10%.

Key words: Fermentated Casava Meal (FCM), Amylomyces rouxii

Broiler - About a type of chicken

Broiler - About a type of chicken

A broiler is a chicken slaughtered for meat while it is still young and tender. Modern commercial broilers are specially bred for meat production and grow much faster than egg breeds. Both male and female broiler turkeys are slaughtered for their meat.

Before the development of modern meat breeds, broilers consisted mostly of young male chickens (cockerels). The males were slaughtered for meat and the females (pullets) were kept for egg production. Compared to today, this made chicken meat scarce and expensive compared to eggs, and chicken was a luxury meat. The development of special broiler breeds decoupled the supply of broilers from the demand for eggs. This, along with advances in nutrition and incubation that allowed broilers to be raised year-round, allowed chicken to become a low-cost meat.


Broilers are often called "Rock-Cornish," referring to the adoption of a cross between a White Cornish male and a Barred Rock female. This hybrid was introduced in the Thirties and became dominant in the Sixties. The original cross was plagued by problems of low fertility, slow growth, and disease susceptibility, and modern broilers have gradually become very different from the Cornish x Rock hybrid.

Modern broilers are typically a third generation offspring (an F2 hybrid). The broiler's four grandparents come from four different strains, two of which produce the male parent line and two of which provide the female parent line, which are in turn mated to provide the broilers. The male lines and female lines are not bred for the same traits; for example, the female line needs to be able to lay as many eggs as possible, since the number of eggs laid per hen influences the cost of broiler eggs and hence broiler chicks. Egg-laying ability is less important in the male line, while rooster fertility is very important.

The broiler is raised in a highly controlled environment along with thousands of other broiler chicks. It is given unrestricted access to a special diet of high protein feed delivered via an automated feeding system. This is combined with artificial lighting conditions to stimulate growth and thus the desired body weight is achieved in 4 - 8 weeks, depending on the approximate body weight required by the processing plant. After processing, the poultry is delivered as fresh or frozen chicken to the stores and supermarkets.

Broiler chickens are also popular in small family farms in rural communities, where a family will raise a small flock of broilers.

Broilers are sometimes reared on a grass range using a method called Pastured poultry, as developed Joel Salatin and promoted by the American Pastured Poultry Producers Association.[1]

The term "broiler" is widely known in North America and Australia but not elsewhere in the English speaking world. The term broiler chicken is very widely used in urban Indian cities, as it was in the former German Democratic Republic and still nowadays in some eastern parts of Germany.

Effect of Bitter Melon (Momordica charantia L.) on Growth Performance, Abdominal Visceral Fat, Cholesterol and White Blood Cells in Broilers

Effect of Bitter Melon (Momordica charantia L.) on Growth Performance, Abdominal Visceral Fat, Cholesterol and White Blood Cells in Broilers.

ABSTRACT

A study was conducted to determine the effect of bitter melon (Momordica charantia L.) on growth performance, abdominal visceral fat, cholesterol and white blood cells in broilers. A total of 160 one-day old chicks (80 male and 80 female) were divided into 4 treatment groups of 4 replications (5 chicks per cage). Using the Completely Randomized Design (CRD), chicks were fed diets containing dried bitter melon at levels of 0, 0.05, 0.5 and 5%, respectively, in ad libium. Experimental diets were fed at two phases with 21 and 19 % protein, respectively, and metabolisable energy (Me) at 3,150 kcal/kg (NRC; 1995). Drinking water was provided at all time. Animal were fed for 42 days with 8 broilers per group slaughtered to study abdominal visceral fat.

Results showed that female animal fed 5% dried bitter melon had lower cholesterol level than the other treatment groups at a highly significant difference (P<0.01).>0.05). Although the results were not significant for broilers fed dried bitter melon but abdominal visceral fat percentage tended to decrease by 5% and for broilers fed 0.5% dried bitter melon, growth performance was much better than the other groups.

In conclusion, cholesterol level in blood of broilers fed 5% dried bitter melon was much lower than those of the other groups.

Effects of Used Oil in Broiler Diets on Productive Performance

Effects of Used Oil in Broiler Diets on Productive Performance

Phongphichan Sukhonthanit and Narin Thongwittaya 1/

Abstract

A study on using used oil in broiler diets was performances to evaluate the productive performance. Used oil was incorporated into six experimental diets at levels of 0, 2, 4, 6, 8 and 10% (23% and 20% CP and 3.00 and 3.10 Mcal ME/kg for 0 – 3 and 3 – 5 weeks of age respectively). Arbor Acres commercial chicks (150 birds, from 0 – 5 weeks of age) were in individual cages. Feed and water were provided ad libitum. The experimental treatments were subjected to Completely Randomized Design (CRD). Treatment means were compared using Duncan’s New Multiple Range test.The results showed that feed intake of chick fed used oil at 6 % higher than control group (2,131.08 and 1,976.21 g/b) (P <> 0.05). It was suggested that can be use the used oil in broiler diet at 6 %.
