PERFORMANCE PRODUCTION AND EGG SHELL THICKNESS OF QUAIL (Coturnix coturnix japonica) AT 6-14 WEEKS OLD AT DIFFERENT LIGHTING LENGTH. This study was done to determine the effect of the lighting length on the performance of quail production at 6-14 weeks old. This research was conducted at the experimental laboratory of Animal Production Department, Faculty of Animal Husbandry Sam Ratulangi University Manado, during the period from January 7, 2017 to March 3, 2017. The ration used was SP-22 commercial feed by PT. Sinta Fredmill. The total of quails used were 80 birds. Birds were maintained in a 60cm x 40cm baterrey system, using 5 watts power light. The variables measured were feed consumption, egg production and peak production, egg weight, and thickness of the egg shell. The design used in this study was a completely randomized design with 4 treatments and 5 replications. Each replication of experiment involved 4 quails with the treatments; R0 = 12 hours of illumination; R1 = 16 hours of illumination; R2 = 20 hours of illumination; R3 = 24 hours of illumination. Feeding and drinking water were prepared ad libitum. The result of the analysis showed that duration of lighting did not affect the averages of feed consumption, egg production, egg weight and egg shell thickness, but peak production could be reached more than 80% at the thirteenth week. Therefore, it can be concluded that the addition of light for female quail production at 6-14 weeks old did not affect feed consumption, peak production, egg weight, and thickness of the egg shell Keywords: Quail, performance production, lighting length illumination

Carbon Dioxide Co2

Ten layer farms (eight from Manikganj and two from Gazipur) were selected to evaluate the effect of the different environmental condition on layer performance. Temperature (°C) and relative humidity (%) were recorded and concentrations of carbon dioxide (CO2, ppm) and ammonia (NH3, ppm) were determined. Productive performance of flock was evaluated by measuring egg production, feed consumption, egg weight and egg shell thickness. The tolerable temperature for the layer was 15-27°C. High temperature (above 27°C) affects feed consumption, egg weight and egg shell thickness while relative humidity has less impact on egg production, egg weight and feed consumption. Feed consumption and egg weight were decreased markedly when CO2 and NH3 concentration were more than 3000 and 37 ppm, but not on egg shell thickness. Postmortem examination indicated that 51, 24, 11, 9 and 5% birds were died due to bacterial, viral, non-infectious, protozoal and fungal infection respectively. Improper environments reduced the chickens’ defenses, making them more vulnerable to diseases. Keywords: Temperature; Humidity; CO2; NH3; Layer performance DOI: 10.3329/jbau.v8i2.7934 J.

Two experiments were conducted to compare the performance of Leghorn hens fed a barley-based diet (68.93%) containing three levels of a Trichoderma viride enzyme supplement (0, 100 and 200 mg kg−1 as treatments T2, T3 and T4, respectively) with those obtained when fed a corn-based diet (Treatment T1). In exp. 1, 80 hens were used to determine performance during four 28-d periods, between 21 and 37 wk of age. Egg production, feed consumption, feed efficiency and egg weight of the hens were not affected by enzyme supplement and were similar to those of hens fed the corn diet (P > 0.05). There were also no significant effects on feed consumption per gram of egg or per bird per day (P > 0.05). There was a significant interaction for egg weight between enzyme addition and periods (P < 0.034), indicating that enzyme supplementation improved egg size in the early periods. In exp. 2, 20 hens were fed the same diets to measure water consumption and the ratio of water to feed consumption. Water consumption was not affected (P < 0.07) but the ratio of water to feed was significantly reduced (P < 0.0005) when enzyme was added to the barley-based diet. Water consumption in g d−1 was 172 for T1, 215 for T2, 211 for T3, and 195 for T4, and the water to feed ratios were 1.40, 1.85, 1.66, and 1.56, respectively. These results demonstrate that barley can replace corn in layer diets and that the addition of enzyme to barley-based diets appears to improve egg size and to reduce water consumption relative to feed intake in young laying hens.

Six diets containing five levels of methionine and two of lysme were each fed to 12 Leghorn and 12 Australorp pullets for a period of 16 weeks Body weight changes, egg production, egg weight and feed intake were measured Although responses to the diets did not differ significantly In univariate analyses, multrvarrate analysis lndicated a srgnificant interaction between breeds and diets. Increased methionine produced small, significant Increases In egg weight, although responses were inconsistent at different levels Body weight gains were not significantly different between diets. Egg production and feed consumption were significantly affected by diet?, but the pattern of response was also inconsistent. A discriminate function analysis showed a consistent response to increased methionine, which indicated that the basal diet was deficient and that the pullets required a total of 0 275% methionine in their diet Lysine supplementation produced a 'significant decrease In feed intake but had no significant effect on any other variable.A multiple regression equation relating metabolizable energy intake to the variables measured in the experiment was calculated and compared with others reported In the literature This was used to predict the requirements of the pullets for a number of essential amino acids.

EFFECT OF LIGHT BULB COLOR ON EGG PRODUCTION OF QUAILS  (Coturnix Coturnix japonica). The present study was conducted to determine the effect of different color of light bulbs on egg production of Quails (Coturnix Coturnix japonica).  The trial was conducted for seven weeks during the egg laying period. A Completely Randomized Design (CRD) with 4 treatments and 5 replications was used to as experimental design. Treatments were formulated using 5 different light bulb colors, as follow:  R0 = no color (transparent) light bulb, R1 = yellow color light bulb; R2 = green color light bulb, and R3 = red color light bulb. The variables measured were: feed consumption, egg production, and egg weight. Research results showed that treatment did not significantly (P > 0.05) affect daily feed consumption, egg production, and egg weight. It can be concluded that color differences (transparent, yellow, green, and red) in lighting can be used interchangeably in Quail egg production purposes.Keywords: Light bulb color, Quail, feed consumption, egg production, egg weight
