Poultry Nutrition

Today the use of enzymes is common in practical poultry nutrition. Enzyme supplementation usually result in numerous beneficial effects, such as increased utilization of nutrients (e.g. fat & protein), improved AME values, increased growth rate, improved feed conversion ratio, decreased viscosity of intestinal digesta, reduced incidence of sticky excreta and improved litter conditions (Broz and Ward., 2007). The use of multi enzymes to improve the digestibility of corn-soybean meal-wheat diets for broilers is less well documented than wheat and barely diets. Therefore, the aim of the present study was to examine the effects of a multi-enzyme supplementation on the performance of broiler chicks fed on corn-soybean meal-wheat diets.

Brewer's Yeast

Following disparity of earlier results, this study tested the performance of African catfishClarias gariepinusfed dried brewer’s yeast slurry meal (DBYM) based diets. Fingerlings ofC. gariepinuswith pooled mean initial weight of1.58±0.01 g were stocked in hapas (1 m × 1 m × 1 m) immersed in an earthen pond at a density of 15 fish per cage. Five diets with increasing substitution of soybean meal with 25%, 50%, 75%, and 100% of dried brewer’s yeast and a control without dried brewer’s yeast (0% substitution) were evaluated for 8 weeks. Palatability of diets reduced with increasing levels of DBYM. Growth and utilization parameters such as weight gain, feed conversion ratio, protein efficiency ratio, and specific growth rate differed significantly (p<0.05) among treated groups. Specific growth rate decreased with increasing substitution while the best feed conversion ratio was obtained in the diet devoid of DBYM. Protein efficiency and utilization decreased with increasing levels of DBYM. Body composition was also affected by inclusion of DBYM with significant differences (p<0.05) being observed across the diets. The trend in body composition follows the utilization of the diets. We conclude that the optimal range of inclusion and substitution of soybean meal with DBYM inC. gariepinusfeed is between 1% and 14% of dry matter.

Starch Diet

In total, 1400 1-day-old male Ross 308 broiler chicks were used to examine the effects of inclusion of alternative carbohydrate and protein sources in prestarter diets and the form of diet on subsequent performance, physiological development and carcass characteristics of broilers. The experimental diets were offered from 1 to 7 days of age and were as follows: control maize–soybean–fish meal diet (CON); maize–soybean meal–casein–dextrose diet (CD); maize–soybean meal–casein-maize starch diet (CS); maize–soybean meal–maize gluten–dextrose diet (GD); and maize–soybean meal–maize gluten–maize starch diet (GS). Each diet was provided in either solid or semi-moist (30% moisture) form, resulting in 10 dietary treatments in a 5 × 2 factorial arrangement. During the first week, a significant (P < 0.05) decrease in feed intake and weight gain was observed in the chicks receiving the CD or the CS diets compared with the chicks receiving the CON diet. Chicks receiving the CON diet also exhibited lower (P < 0.05) feed conversion ratio than did those receiving the CD or the CS diets. The adverse effect of feeding the CD and CS diets on liveweight of the birds was still evident at 21 and 42 days of age (P < 0.05). Chicks on the semi-moist diets consumed less (P < 0.05) feed than those on the solid diets during the first week. Nevertheless, chicks fed the semi-moist diets had higher (P < 0.05) weight gain and exhibited lower (P < 0.05) feed conversion ratio than did those fed solid diets. During the entire period, the highest weight gain and feed intake were observed in chicks receiving the CON prestarter diet in semi-moist form. During the first week, chicks receiving the CD or the CS diet exhibited the lowest (P < 0.05) small intestine weight and length. Conversely, at the age of 21 days, these chicks had higher (P < 0.05) small intestine weight than did the other chicks. It can be concluded that using a maize–soybean–fish meal-based prestarter diet in semi-moist form improves chick development and positively affects growth performance.

Heavy Mortality

A diet, based on wheatmeal and soybean meal, was fed to chickens and was shown to be deficient in sodium but not in chloride, using reduced growth rate from 14 to 20 days of age as the main criterion of deficiency. The same diet fed to chickens from hatching to five weeks of age produced almost complete cessation of growth during the last week, caused heavy mortality, greatly impaired feed conversion, and increased adrenal gland size in relation to body weight. Using this diet and additions of sodium, the minimum sodium requirement was estimated to be 0.18 per cent of the diet for maximum growth and minimum feed conversion ratio, and slightly lower than this for maximum viability and minimum adrenal gland activity.

Background: Alternative protein sources to fishmeal in fish feeds are needed. Objectives: Evaluate rearing performance of adult rainbow trout (Oncorhynchus mykiss) (initial weight 139.0 ±1.5 g, length 232.9 ± 0.8 mm, mean ± SE) fed one of the two isonitrogenous and isocaloric diets (46% protein, 16% lipid) and reared at one of the two levels of exercise (water velocities of either 3.6 cm/s or 33.2 cm/s). Methods: Protein in the control diet was based on fishmeal. In the experimental diet, bioprocessed soybean meal replaced approximately 60% of the fishmeal. Fish were fed by hand once-per-day to near satiation, and the food was increased daily. The experiment lasted 90-days. Results: There were no significant differences in gain, percent gain, or specific growth rate between the dietary treatments. However, the amount of food fed and feed conversion ratio was significantly lower in the 60% bioprocessed soybean meal diet. Intestinal morphology, relative fin length, splenosomatic index, hepatosomatic index, and viscerosomatic index were not significantly different in the trout fed either diet. Fish reared at 3.6 cm/s had a significantly lower feed conversion ratio (1.02 ± 0.02) than fish reared at 33.2 cm/s (1.13 ± 0.02). However, there were no significant differences in gain, percent gain, specific growth rate, or percentage mortality in fish reared with or without exercise. No significant interactions were observed between diet and exercise (higher water velocity). Conclusion: Based on these results, at least 60% of the fishmeal in adult rainbow trout diets can be replaced by bioprocessed soybean meal, even if higher water velocities are used to exercise the fish.

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

Silk Worm

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.
