OBJECTIVES/SPECIFIC AIMS: It has been reported that birth mode affects development, with cesarean section born mice gaining more body weight during development. Since mice C-sections involve fostering and nest change, we sought to determine whether changing only the nest and cage would have an effect on development. METHODS/STUDY POPULATION: A total of 53 mice were born to 9 dams, and 21 babies (4 litters) were exchanged in pairs to foreign cages and nests. Litters were followed for body weight and mothers were observed during periods for maternal and nonmaternal behaviors. RESULTS/ANTICIPATED RESULTS: The results show that average body weight was significantly higher in the experimental group in both genders, with 20% higher body weights at weaning. The mothers from the litters that were changed to a new nest showed significantly more non-maternal behavior in the first 2 days if life, than the controls. DISCUSSION/SIGNIFICANCE OF IMPACT: The results suggest that changes in maternal behavior may be linked to the increased weight gain in their babies.

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

Determining the optimum level of lysine in the ration will be a significant effort to avoid poor growth in duck husbandry. The purpose of this study was to determine the optimum dietary lysine requirement for EPMp broiler ducks, raised up to 10 weeks of age. The study was designed in a completely randomized design (CRD) with 4 dietary treatments, and 4 replicates. Each replicate consisted of 10 ducks. The 4 treatments were diets, containing lysine: 0.60% (T1); 0.70% (T2); 0.80% (T3) and 0.90% (T4). Variables measured included: feed consumption, body weight gain, feed conversion ratio (FCR), carcass and carcass cuts percentages. The results showed that the performance of 10 weeks of age EPMp broiler duck was significantly affected by the level of dietary lysine (P<0.05). The average body weight gain and the FCR of the duck were significantly affected (P<0.05) by dietary lysine level, but not for feed consumption and percentage of carcass (P>0.05). The average body weight gain of EPMp duck with T4 treatment (0.90% lysine) was significantly higher than that T1 (0.60% lysine) but did not significantly difference (P>0.05) with T2 and T3. The average FCR of EPMp duck under T3 and T4 were significantly (P<0.05) higher than that of EPMp duck under T1. It was concluded that the optimum dietary lysine to produce maximum body weight gain of EPMp duck raised up to 10 weeks of age was 0.70%, while for minimum FCR were at the level of 0.80% and 0.90%.

Oxygen uptake (VO2) through the gills of a hill-stream fish Glyptothorax telchitta from the Saptakoshi river (Nepal) has been studied in relation to different body weights. The oxygen uptake was determined at 24.0±1°C using a cylindrical glass respirometer with continuous water flow system. The aquatic oxygen uptake through the gills increased from 1.048 to 8.115 mlO2 kg-1.h-1 within the body weight range of 3.215 to 31.355 g. A fish of 17.052 g average body weight consumes 4.461 mlO2-1.h-1. The relation between oxygen uptake (VO2) and body weight was determined by performing regression analysis using logarithmic transformation. It has been found that with a unit increase in body weight, the oxygen uptake per unit time (mlO2h-1) increases by a power of 0.930 showing significant positive correlation whereas, the weight specific oxygen uptake decreases by a power of 0.070 showing significant but negative correlation.

Two experiments were carried out to study the effects of grinding of soybean hulls (SH) on starting pigs (15-30 kg) diets. Experiment I consisted of a digestibility trial with 12 barrows, initial average body weight 21.9±1.29 kg, in which the best digestibility coefficient (DC) of DM and GE was obtained with SH ground through a 2.5mm screen mesh, evaluated for CP and ME, a best DC was attained with 3.0 mm screen mesh. In the Experiment II, five diets with increasing SH (2.5 mm) levels (0, 3, 6, 9 and 12 %) for starting piglets were formulated. A quadratic response in daily weight gain (DWG) occurred, according to SH inclusion. Worst DWG occurred at 7.75 % SH inclusion. Daily feed intake, feed: gain ratio and plasma urea nitrogen were not affected by inclusion levels. In conclusion, although soybean hull grinding improves the digestible nutrients, inclusion of SH on starting pig diets is economically unfeasible.

A study was conducted to determine the growth performance and mortality rate of Khaki Campell, Jinding and Deshi genotypes in two coastal locations of Barisal and Bhola districts of Bangladesh. Sixty-day-old ducks of 3 genotypes were randomly allocated to 3 treatments having 4 replications in each. Ducks are reared up to 150 days and at the end of experiment one male Khaki Campbell of highest live weight was selected from each replicate group. The average weekly body weight gain (g/bird) of the Khaki Campbell and Jinding were significantly (p<0.01) higher than those of the Deshi ducks. The average body weight of Khaki Campbell (1480.25g) was slightly higher than that of Jinding (1428.25g) but significantly (p<0.01) higher than that of Deshi (1140.62g) ducks at the end of the experiment. The mortality rate were significantly different (p<0.01) in various genotypes. The highest mortality was found in Deshi (30.20%) compared to Khaki Campbell (19.79%) and Jinding (17.77%). The profit margin was significantly different (p<0.01) in three genotypes. The ducks reared in Barishal performed better (p<0.01) than that from Bhola. It may be suggested from the present findings that both Khaki Campbell and Jinding ducks are performed better than Deshi in the coastal region of Bangladesh.http://dx.doi.org/10.3329/bjas.v41i1.11971

The experiment was performed on 60 male French Lop rabbits reared under extensive conditions and sacrificed at body weights of approximately 3 kg at the age of 150 d (30 animals) and approximately 4.5 kg at the age of 210 d (30 animals). Chilled carcasses without heads were divided into the front, middle and hind sections, which were then dissected to separate lean meat (including intramuscular fat), fat and bones. An increase in the body weight of rabbits at slaughter was accompanied by a decrease, of about 0.60%, in the proportion of the head and giblets (kidneys, liver, heart and lungs) in the carcass, and by an increase in the perirenal fat content from 0.66 to 1.69%. The average carcass dressing percentage of rabbits sacrificed at an average body weight of 3054 g reached 49.13%, and it was 2.49% higher than in rabbits slaughtered at a body weight of 4427 g. The percentage content of the front, middle and hind sections of the carcasses of the lighter rabbits was 38.50, 21.76 and 39.74%, respectively. In the carcasses of the heavier rabbits, the proportion of the front section was 2.29% higher, the proportion the hind section was 2.45% lower, while the proportion of the middle section remained at a similar level as in the lighter rabbits. The carcasses of the lighter rabbits, compared with the carcasses of the heavier rabbits, had a higher percentage content of meat (82.60 vs. 81.15%; P ≤ 0.01) and a lower percentage content of fat (1.78 vs. 4.38%). In addition, rabbits sacrificed at a body weight of approximately 3.0 kg were marked by a higher content of lean meat in the middle and front sections of the carcass (by 1.89 and 3.07%, respectively), and by a slightly lower content of lean meat in the hind section (by 0.85%).
