Abstract

The objective of this research was to study the effect of restricted feeding on muscovy duck performance’s in grower period, the development of reproduction organ, puberty characteristic, egg production, and blood lavel of cholesterol and trigliseride. Total 32 of female muscovy duck , 8-22 weeks age ware evaluated in this research. A completely randomized design with 3 level treatments were used to arrange the treatments. The treatments of restricted feeding were ad libitum consumption ( P1); 70% ad libitum (P2) and 40 % ad libitum (P3). The diet contain 22% crude protein (0-3 weeks age), 18% crude protein (4-7 weeks age), and 14% crude protein (8-22 weeks age). The parameters observed were: performance’s in grower period (feed consumption, body weight, total daily gain), puberty characteristic (puberty age, body weight on puberty, first egg weight), egg production on first cycle, the development of reproduction organ, and blood lavel of cholesterol and trigliseride. The results showed that body weight of muscovy duck P2 and P3 lower then P1. The restricted feeding could delayed development of folicle ovary and  age puberty. The blood level of cholesterol’s muscovy duck P2 and P3 lower then moscovy duck P1.

Abstract

Indonesia local duck has the potential to produce meat, but its growth is still slow. Therefore it needs the effort to improve the performance. One of the effort is using feed additive in the diet. Feed additive aimed to be appetizer and improve performance. Materials that can be used as feed additive are beluntas and kenikir because of their active compounds that can increase the appetite. This study aimedto examine the performances of local duck fed beluntas or kenikir as feed additive. The experimental design used was randomized design with 7 treatments and 5 replications. The treatment was the addition of beluntas or kenikir leaf meal in the diet during 1, 2or 3 weeks before being slaughtered. Variables observed were feed consumption, fenolik and tanin consumption, body weight, weight gain, percentage of carcass, chest, thigh, and abdominal fat. The results showed that the effects of beluntas or kenikir were not significant on performance (feed consumption, fenolik consumption, tanin consumption, body weight, and feed conversion) as well on carcass quality (carcass, abdominal fat, meat-bones of chest and thigh). Feeding beluntas or kenikir leaf meal 1% for 1, 2 or 3 week as feed additive did not improve the performances of local duck.

Abstract

Air flow distribution, temperature, and humidity in the cage will differ from the inlet to the outlet. Microclimate difference in the cage at the inlet to the outlet can affect the production and quality of the eggs produced. The purpose of this research was to study the performance of laying hens on different location of cage (inlet, middle and outlet) in closed house system. In total 36 Lohmann hens were placed in each treatment including cage inlet, middle, and outlet. Traits measured were productive performance (hen day performance and egg weight) and egg qualities (haugh unit and egg shell thickness). The data were be analyzed using anova, tukey test, pearson correlation coefficient and completely randomized design. Result showed that here was very significant different on different location cage between temperature, relative humidity, and wind velocity. Cage inlet resulted better performance of laying hens compared to the middle and outlet cage.
