温度和食物对褶皱臂尾轮虫种群增长及繁殖的影响

本试验设3个温度（20、25和30℃）和3个食物浓度（1×106、10×106和20×106 cells/mL）,研究不同温度和不同食物浓度对褶皱臂尾轮虫种群增长及繁殖的影响。试验期为10 d。结果表明,最大种群密度均随温度和食物浓度的升高而先增加后减少。温度为25℃食物浓度为10×106 cells/mL时,最大种群密度为74.39±1.81 ind/mL,与其他组比差异显著（P〈0.05）。随温度升高,轮虫的最大种群密度高峰值出现的时间也呈现逐渐前移的趋势,最大种群增长率则随温度和食物浓度的增加而升高。温度30℃食物20×106 cells/mL时,最大种群增长率为0.70±0.013,与其他组比差异显著（P〈0.05）。食物浓度对轮虫的怀卵率有显著影响,在同一温度下最大怀卵率随食物浓度的升高而增大,食物为20×106 cells/mL的最大怀卵率为56.43±1.07%,与其他浓度组比差异显著（P〈0.05）。在本试验条件下,温度和食物对褶皱臂尾轮虫的种群增长及繁殖均有显著影响。温度25℃食物浓度10×106 cells/mL为培养条件的最优组合。     

Raw mechanically separated chicken meat and salmon protein hydrolysate as protein sources in extruded dog food: effect on protein and amino acid digestibility

Protein quality was evaluated for mechanically separated chicken meat (MSC) and salmon protein hydrolysate (SPH), and for extruded dog foods where MSC or SPH partially replaced poultry meal (PM). Apparent total tract digestibility (ATTD) of crude protein (CP) and amino acids (AA) in the protein ingredients and extruded foods was determined with mink (Neovison vison). The extruded dog foods included a control diet with protein from PM and grain, and two diets where MSC or SPH provided 25% of the dietary CP. Nutrient composition of the protein ingredients varied, dry matter (DM) was 944.0, 358.0 and 597.4 g/kg, CP was 670.7, 421.2 and 868.9 g/kg DM, crude fat was 141.4, 547.8 and 18.5 g/kg DM and ash was 126.4, 32.1 and 107.0 g/kg DM for PM, MSC and SPH respectively. The content of essential AA (g/100 g CP) was more than 10.0 percentage units lower in SPH than in PM and MSC. The ATTD of CP differed (p < 0.001) between protein ingredients and was 80.9%, 88.2% and 91.3% for PM, MSC and SPH respectively. The ATTD of total AA was lowest (p < 0.001) for PM, and similar (p > 0.05) for MSC and SPH. In the extruded diets, the expected higher ATTD of CP and AA from replacement of PM with MSC or SPH was not observed. The ATTD of CP was determined to be 80.3%, 81.3% and 79.0% for the PM, MSC and SPH extruded foods respectively. Furthermore, the ATTD of several AA was numerically highest for the PM diet. Possibly, extrusion affected ATTD of the diets differently due to different properties and previous processing of the three protein ingredients.

Performance of Broiler Chickens Fed Sweet Potato Meal (Ipomoea batatas L.) Diets

Day-old Lohman broiler chicks (n = 120) were fed on five starting diets for 4 weeks in groups of 24 birds. The starting diets contained 0%, 9%, 18%, 27% and 36% sweet potato tuber as a replacement for maize. From the fifth week, the 120 birds were tested in groups of 30 on four finishing diets containing 0%, 15%, 30% and 45% sweet potato tuber as a replacement for maize. The carcass quality was significantly (p>0.05) improved due to a significant (p>0.05) reduction of abdominal fat in the birds fed on the 45% sweet potato finisher diets. However, the birds on the sweet potato diet continually passed wet dropppings, resulting in a significant (p>0.05) reduction in body weight and feed conversion efficiency. The optimum levels of inclusion of sweet potato in the diets were considered to be 27% and 30% for starting and finishing broiler chickens, respectively. Sweet potato diets may be a remedy for fatty broilers.
