The possibility of improving the nutritional quality of plant byproducts (brewers’ spent grain and rice bran) through an enzyme treatment was tested in a formulated feed for grey mullet (Mugil cephalus). The enzyme treatment was carried out by Solid-State Hydrolysis (SSH) using a commercial preparation including carbohydrases and phytase. A feed prepared without the treatment and a commercial feed for carp were used as controls. In a preliminary short-term trial carried out at laboratory facilities, fish receiving the enzyme-treated feed showed significant improvement in both FCR and SGR when compared to those obtained with the untreated diet, although both experimental diets presented worse values than those obtained with the commercial feed. Different metabolic indicators including higher values of muscle glycogen and plasmatic triglycerides supported the positive effect of the enzyme treatment on the nutritional condition of the fish over those fed on the diet containing non-treated ingredients. Results of growth and feed efficiency that were obtained in a second long-term trial developed for 148 days under real production conditions evidenced the equivalence among the experimental and commercial diets and confirmed that enzyme pretreatment of plant ingredients by SSH may be a useful procedure to improve the nutritive value of high fiber plant byproducts when included in practical diets for this species and others with similar nutritional features.

Two studies were undertaken to evaluate the nutritive value of high fiber canola meal (HFCM) relative to regular canola meal for ruminants. In the first study, 21 growing lambs were utilized in a randomized complete block design to determine the total tract digestion coefficients of dry matter (DMD), crude protein (CPD), gross energy (GED), neutral (NDFD) and acid (ADFD) detergent fiber and the digestible energy (DE) contents of seven dehydrated alfalfa-based diets containing 0, 250, 500 and 750 g kg−1 HFCM or canola meal. In the second study, the effect of feeding HFCM as a protein supplement to dairy cows relative to canola meal and soybean meal (SBM) was examined in a triple 3 × 3 Latin square design. Results of the first study showed that HFCM had lower (P < 0.05) DMD, CPD, GED and DE contents than canola meal. The estimated DMD, CPD and GED and DE contents for HFCM were 674 and 795 g kg−1, 695 kJ MJ−1 and 13.68 MJ kg−1, respectively. The corresponding values for canola meal were 707 and 841 g kg−1, 727 kJ MJ−1 and 14.10 MJ kg−1, respectively. Results of the second study showed that protein supplement source had no effect on DM intake, milk yield, milk fat g kg−1, lactose g kg−1 and total solid g kg−1. However, cows fed HFCM- and canola meal-based diets produced milk with lower (P < 0.05) protein content than those fed the SBM-based diet. It was concluded that HFCM had lower total tract nutrient digestion coefficients and DE content compared with canola meal. Incorporation of HFCM in dairy rations up to 100 g kg−1 of the ration had no adverse effect on milk yield or milk composition compared with canola meal. Key words: High fiber, canola meal, total tract digestibility, lactation

Selection Of

The Mugilidae are a group of fish with a great interest for aquaculture due to their omnivorous profile, rapid growth, and resistance to environmental variations. The selection of feed ingredients for these species is currently focused on an extensive use of plant by-products, with this being limited by their content in anti-nutritive factors (mainly phytate and non-starch polysaccharides; NSPs). Nevertheless, specific enzymes can be used to counteract some of those negative effects. In the present study, the effect of pretreating two high-plant feeds with a mixture of enzymes (glucanases + phytase) on the digestive use of protein and phosphorus by juvenile mullets (Mugil cephalus) was assessed using both in vitro and in vivo assays. The enzymatic treatment significantly modified the potential bioavailability of some nutrients, such as a reduction of sugars, pentoses, and phytic phosphorus. Also, it increased the digestibility of protein in one of the feeds but reduced that of phosphorus in both of them. The potential usefulness of enzyme treatment and the information provided by the two types of assays are discussed.

This study aimed to examine the effect of turmeric and garlic inclusion to fermented Sauropus androgynus-bay leaves (FSBL) containing diet on fat deposition, and chemical composition of broiler meats. Two hundred 15-day-old female broilers were distributed into 5 treatment groups with 4 replications as follows. Control feeds with commercial feed additive (T0); Feeds with 1.25% FSBL (T1); Feed with FSBL plus 1 g turmeric (T2); Feed with FSBL plus 2 g garlic (T3); Feed with FSBL plus 1 g of turmeric and 2 g garlic (T4). It was shown that the fat deposition in the abdomen was significantly affected (P<0.01). Furthermore, the inclusion of turmeric and garlic to FSBL containing diet did not affect fat, protein, moisture and ash contents, but increased arginine, methionine and histidine (P<0.01). The addition of turmeric and/or garlic to the FSBL containing diet significantly influenced lauric acid, myristic acid, linolenic acid, cis-11-eicosenoic acid, cis-4,7,10,13,16,19-docosahexaenoic acid (P<0.05), n-3 fatty acid and n-6/n-3 fatty acid ratio (P<0.01). In conclusion, turmeric plus garlic supplementation improved amino acid profiles and changed fatty acid profiles. The possible interaction should be considered when we formulated feed additive from medicinal plant mixtures

This study was conducted to evaluate the combination of ginger and turmeric extracts added with Lactobacillus spp. (GTL) on body resistance and productivity of broilers. 576 broilers with an initial body weight of 36 ± 0.99 g were used and were observed for 35 days. GTL containing ginger extract (0.2 g/liter), turmeric extract (0.4 g/liter) and Lactobacillus spp. (2,997 x 107 cfu/ml), and was given since 1-day old. Parameters observed were bursa fabriscius, spleen, and thymus weights, gluthationine peroxidase (GSH-Px), superoxide dismutase (SOD), Lactobacillus spp., Coliform, and Eschericia coli, feed consumption, body weight gain, and feed conversion ratio (FCR). A completely randomized design (CRD) was assigned with 3x4 factorial pattern (3 types of feed, 4 levels of GTL), with 4 replications (12 birds each). First factor, types of feed (A): self-formulated feed (A1), combination of self-formulated and commercial feed with 50 portion each (A2) and commercial feed (A3). Second factor, levels of GTL (B): 0 ml (B0), 2 ml (B2), 4 ml (B4) and 6 ml (B6) per litre drinking water. Data were subjected to ANOVA and continued to Duncan test at 5% probability. Results indicated that self-formulated feed with inclusion of GTL at 4 ml (A1B4) improve body resistance and increase production performance of broilers.

High Fiber Diet

We studied the effects of dietary fiber, of plant versus animal diets, and of diet diversity on the digestive organ morphology of captive Mallards (Anas platyrhynchos). Four experimental diets were used: whole corn (low fiber, plant), trout chow (low fiber, primarily animal), rabbit chow (high fiber, plant), and a diverse diet consisting of each of the preceding diets fed daily in random order. Every 5 days for 25 days, we sampled birds from each diet group (N = 6–8) and weighed each bird and its abdominal fat, gizzard, ceca, small intestine, and liver, and then measured its ceca and small intestine length. Other than differences explained by their different body sizes, the sex of the birds had no effect on gut measurements. Changes in body weight and abdominal fat weight suggested that Mallards existed equally well on each of the four diets, presumably because changes in their digestive organs allowed them to have similar digestive efficiencies when eating different diets. Birds on the high fiber diet had the largest digestive organs, but birds on all diets showed changes in digestive organs. The diverse diet produced effects on digestive organ morphology similar to those of the two low-fibre diets. Except for a larger gizzard for macerating corn in birds on that diet, there was no difference in the digestive organs between birds eating animal foods and those eating low fiber plant foods. The maximum weight of gizzard, intestine, and ceca of birds on the high fiber diet was reached in 10 days. However, ceca and intestine lengths of these birds were still increasing after 25 days. This observation suggests that birds can continue to respond to a change in diet after limits to the mass of their digestive organs have been reached.

Solid state fermented pigeon pea meal (FPP) was used in substituting fish meal (FM) in diets of Oreochromis niloticus. Five diets varying in inclusion levels of FM: FPP as followed: Feed 1, 250:50; Feed 2, 200:100; Feed 3, 150:150; Feed 4, 100:200 and Feed 5, 50:250 were made. A commercial feed (Feed 6), was used as a control. Triplicate groups of tilapia fingerling were stocked in plastic aquaria at six fish per unit and fed ad libitum for 60days. Results showed that specific growth rate (SGR) of tilapia fed Feed 5 (2.60±0.12% day-1) was better (p<0.05) than those recorded in Feed 1 (2.36±.07 % day-1). Similarly, food conversion ratio (FCR) (1.13±0.01) and mean weight gain (60.00±0.04g) were higher (p<0.05) in Feed 5 when compared with those in Feed 1 where FCR was 1.19±0.02 and MWG (50.96±0.04g). The results of Aspartate amino transferase (AST) and alanine amino transferase (ALT) decreased with increasing inclusion level of FPP. Gut microbial load increased with increasing level of FPP. The fish group fed Feed 5 had the highest foregut (2.60 x 10-5 CFU/ml), midgut (3.98 x 10-5 CFU/ml) and hindgut (4.52 x 10-5 CFU/ml) micrbiota. In general, gut microbiomes were dominated by cellulose and carbohydrate utilizing bacteria: Citrobacter fruendi, Bacillus subtilis and Staphylococcus aureus. Inference from the study revealed that O. niloticus was able to utilize the diets due to the presence of probiotics in them.

Quebracho (Loxopterygium loetzil) tannins (QT) are condensed tannins that reduce the digestibilities of nutrients in ruminants (Robbins, et al, 1991), probably by forming complexes with the dietary protein and carbohydrates and reducing microbial activities (Makkar, et al, 1988). Browse Plus (BP), a commercial preparation of polyethylene glycol (PEG) has recently been used to improve the nutritive value of tannin-containing browses. Trials on commercial farms in Zimbabwe have demonstrated that BP improved the nutritional performance of cattle fed high tannin diets (Anon., 1995). Some in vitro work tend to support these findings (Acamovic, et al, 1995). An experiment to study the effectiveness of BP in ameliorating the effects of QT on the rumen environment was conducted.
