A study was conducted to the determine the effects of concentrate supplimentation on performance and nutrient digestibility in cane-rats/grasscutters. There were initiall three treatments: 0%, 10% and 20% concentrate supplementation onas fed basis to a basal elephant grass diet. Fifteen weaned cane-rats with average body weights of 1150g(士365.40) were randomly assigned to the three treatments based on weight and sex. The growth study was conducted for eight weeks. A nutrient digestibility study was also conducted using three grasscutters per treatment. The cane-rats fes 20% supplementary concentrate gained more weight than those offered 10% concentrate feed. Crude protein was better (p<0.05) digested by cane-rats on 20% concentrate feed whereas, ash and ether extract digestibility were better on 10% concentrate feed. The 0% concentrate treatment was terminated because three of the cane-rats(68% mortality) died within three weeks of the study. It is recomendedfrom this study that cane-rats fed a basal grass diet should be supplemented with 20% concentrate on as fed basis

Abstract An experiment was conducted to test the hypothesis that Cu hydroxychloride improves nutrient digestibility and alters the concentration of microbial protein in the small intestine or large intestine by pigs fed a corn-soybean meal diet or a diet based on corn, soybean meal, and distillers dried grains with solubles (DDGS). Twenty-four barrows (33.3 ± 3.4 kg) that had a T-cannula installed in the distal ileum were allotted to a 2 × 2 factorial design with 2 levels of DDGS (0% or 45%) and 2 levels of supplemental Cu from Cu hydroxychloride (0 or 150 mg/kg). A 2-period switch back design with the 4 diets and 6 replicate pigs per diet in each period was used resulting in 12 replicate pigs per diet for the 2 periods. The initial 9 d of each period was considered an adaptation period to the experimental diets. For each period, feces were collected on days 10, 11, and 12, and ileal digesta were collected for 8 h on days 13 and 14. Results indicated that inclusion of 45% DDGS to diets reduced (P &lt; 0.05) the apparent ileal digestibility (AID) of AA and the AID and the apparent total tract digestibility (ATTD) of dry matter, gross energy, and crude protein. In contrast, inclusion of DDGS to diets increased (P &lt; 0.05) the AID and the ATTD of acid hydrolyzed ether extract and the concentration of microbial protein in the hindgut (P &lt; 0.05). However, the total concentration of volatile fatty acids (VFA) in ileal digesta and in feces from pigs fed the DDGS diets were not different from concentrations in pigs fed diets without DDGS. The AID and ATTD of dry matter, gross energy, and crude protein were not affected by dietary Cu concentrations, but the AID and ATTD of acid hydrolyzed ether extract were greater (P &lt; 0.05) in diets supplemented with Cu hydroxychloride compared with diets without Cu hydroxychloride. There was also a reduction (P &lt; 0.05) in the concentration of microbial protein and a tendency for a reduction (P &lt; 0.10) in the total concentration of VFA in feces when diets were supplemented with Cu hydroxychloride. In conclusion, supplementation of Cu hydroxychloride to diets improved AID and ATTD of acid hydrolyzed ether extract and reduced the concentration of microbial protein in the large intestine and this effect was observed in diets containing DDGS as well as in diets without DDGS.

This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

Nulliparous crossbred does were used to study the effects of concentrate:lablab ratio (CL) and stage of pregnancy on nutrient intake and digestibility. Treatments consisted of four concentrate and lablab combinations on a gram:gram basis: 20:130, 40: 110, 80:70 and 100:50 and two stages of pregnancy: second and fourth week of pregnancy Concentrate intake increased as level increased up to 80g/day offered while lablab intake increased from 50 to 130g/day offered. Doe weight and metabolic size were similar for all treatments. Total feed intake was not affected by concentrate and lablab levels. Dry matter intake was lower for 100:50 CL than other treatments. Ether extract and crude fibre intakes decreased with increase in concentrate levels. Dry matter and nitrogen free extract digestibility were higher for 80:70 CL than other combinations. Crude fibre digestibility was higher for 80:70 than 40:110 and 100:50 CL Crude protein retention was higher for 80:70 than 20:130 and 100:50 CL. Fetal growth requirement, total protein requirement and balance of protein were high at 80:70 and 100:50 CL. During pregnancy, dry matter and all nutrients intake were higher in the second than fourth week. Ether extract, crude protein and nitrogen free extract digestibilities were lower in the second than fourth week of pregnancy. Fetal growth requirement and balance of protein were higher in the second than fourth week of pregnancy relationship between feed intake (g DM/day) and nutrient digestibility was negative. The relationship between feed intake (g DM/kg body weight/day) and feed intake (g DM/kg LW0.75/day) was however, positive for all the nutrients except crude protein. For the small scale rabbit producer in developing countries, it is feasible to maintain rabbits on combinations of concentrate and lablab during pregnancy

The objective of this study was to evaluate the replacement of soybean meal by extruded whole soybean in the feeding of pigs in the nursery phase. Thirty-six piglets (Landrace x Large White), with 45 days weighing on average 11.36 kg, distributed in arandomized block design, three treatments, six replicates, two animals per repetition were used. The treatments consisted of: control treatment (T1) basal diet, basal diet with 10% replacement of soybean meal by extruded soybean (T2), basal diet with 20% replacement of soybean meal by extruded soybean (T3). The variables analyzed were: average weight, feed intake, weight gain and feed conversion. The levels of ureatic activity, ether extract, crude protein, protein solubility and volatile moisture of extruded soybean were verified. No difference was found (P>0.05) between the inclusion levels of extruded soybean in piglet diets in the nursery phase for the variables studied. The processing of extruded whole soybean did not affect its digestibility. Extrudedsoybeans at a level of up to 20% included in piglet feeding during the nursery phase can be a possible substitute for soybean meal, without compromising the performance of the animals.

Mixture of bovine blood and rumen digesta (BBRDM) was evaluated for 56 days as a replacement for soybean meal (SBM) and groundnut cake (GNC) at 100% on protein to protein basis in the diets of growing pigs to assess the nutritive value of BBRDM on the growth performance, nutrient digestibility and cost benefits. Hence, a total of 18 growing pigs were allotted on weight equalization basis into three dietary treatments consisting of six pigs per treatment in a completely randomized design. Three diets were formulated such that T : served as the control diet without BBRDM but contained both soybean meal and 1 groundnut cake. T : BBRDM replaced soybean meal and T : BBRDM replaced groundnut 2 3 cake. Result indicated that BBRDM contained 28.65% crude protein, 13.17% ether extract, 5.26% crude fibre, 11.29% ash and 31.65% nitrogen free extract. Dietary treatments did not significantly (P>0.05) influenced the growth parameters observed in this study. Although there were no significant (P>0.05) difference on the nutrient digestibility parameters investigated but birds in T recorded highest numerical values for crude protein (77.23), 3 crude fibre (62.46%), ether extract (92.33%), nitrogen free extract (89.61%), ash (70.28%) and nutrient dry matter (91.67%) while the least values were obtained from birds in T . Cost 1 of feed decreased with the inclusion of BBRDM while the cost per weight gain also improved with the replacement of the conventional feed ingredients. The result also showed that an appreciable amount of money was saved when BBRDM was included in the ration of growing pigs. It is therefore concluded that BBRDM could be used as an animal protein source to compliment plant protein source such as soybean meal and groundnut cake in the diet of growing pigs.

Two experiments were carried out to investigate the effect of “on top” addition of different enzyme complexes, the enzyme α-galactosidase and three sources of the enzyme phytase available on the market, in broiler diets. In the first experiment, 1260 one-day-old Cobb 500® chicks were distributed into seven treatments in a completely randomized design (CRD) with six replicates and 30 birds/replicate. Treatments consisted of combinations of different enzyme complexes, namely, complex A (phytase, protease, xylanase, ß-glucanase, cellulase, amylase, pectinase), complex B (protease and cellulase) and complex C (xylanase, amylase and protease); isolated α-galactosidase (GAL); and three sources of phytase (P1, P2 and P3) in the diet. The treatments were formulated as follows: T1 - basal diet (BD); T2 - BD + enzyme complex A + enzyme complex B (BDAB); T3 - BDAB + GAL; T4 - BD + complex A + GAL; T5 - BD + complex C + P1 + GAL (BDCG); T6 - BDCG + P2; and T7 - BDCG + P3. The following variables were measured in the experimental period of 42 days: feed intake (FI), weight gain (WG), average final weight (AFW), feed conversion (FC), and carcass yield. Significant differences occurred for AFW, WG and FC in the pre-starter phase. In the second experiment, 112 Cobb 500® chicks aged 25 days were distributed into seven treatments in a CRD with four replicates and four birds/replicate. Treatments were the same as in the first experiment. Nutrient digestibility was evaluated in an experimental period of seven days. Differences were found in the metabolism coefficient of ether extract (MCEE). Dietary inclusion of enzyme complexes improves the AFW and WG of chickens from 1 to 7 days of age and MCEE in the grower phase.

This study aimed to evaluate nutrient intake and digestibility, performance and economic viability of steers during the rearing phase in Brachiaria brizantha cultivar Marandu graze and in feedlot. Were used fifty crossbred steers in the rearing phase, with a mean weight of 275 ± 8.18 kg, distributed in a completely randomized design with ten replications per treatments: Mineral supplementation, nitrogen supplementation, Concentrate supplementation in the order of 1 and 2 g/kg body weight and total feedlot. The total dry matter intake and body weight showed a difference (P<0.05) for animals in feedlot. Crude protein, ether extract, neutral detergent fiber corrected for ashes and protein, non-fibrous carbohydrates, total digestible nutrients showed differences for the animals that received mineral supplementation in comparison to the other managements adopted. The same performance was observed for animals in feedlot. The digestibility coefficients of dry matter, crude protein, ether extract, non-fibrous carbohydrates and total digestible nutrients showed a difference (P<0.05) for the animals that received mineral supplementation, in comparison to the other managements adopted. (P<0.05). The mean daily gain was lower (P<0.05) for animals receiving mineral supplementation. The gross margin was higher (P<0.05) for animals handled in feedlot. Considering the obtained results, it was possible to observe that the animals kept in graze with good availability of dry matter presented satisfactory performance. It is feasible to confine the animals in rearing, since it shortens the production cycle, generating favorable economic results.

The objective of the present study was to evaluate the nutritional value of elephant-grass silages containing annato byproduct. Twenty intact rams were distributed in a complete randomized block design with five diets (0; 4; 8; 12 and 16% annato byproduct in the silage) and four replications and used to estimate the intake, apparent nutrient digestibility, content of total digestible nutrients and nitrogen balance. The addition of annato byproduct raised the intakes of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), total carbohydrates (TC), non-fibrous carbohydrates (NFC) and total digestible nutrients (TDN), in body weight (%BW) and in metabolic weight (g kg-1BW0.75). The digestibilities of DM (55.95%), OM (58.19%), CP (45.34%), NDF (52.79%), ADF (45.79%), EE (34.96%) and NFC (99.86%) were not influenced by the addition of annato byproduct. The inclusion of annato byproduct in elephant-grass silage increased digestibility of total carbohydrates, the TDN content and the nitrogen balance. The aditions of annato byproduct at levels up to 16% of the elephant grass silage natural matter improves nutrient intake and nitrogen balance.

AbstractA study was conducted to compare the digestibility of organic matter (OM), neutral-detergent fibre (NDF), acid-detergent fibre (ADF), hemicellulose and nitrogen (N) and N balance in Mukota (M), Large White (LW) and the LW × M F1 pigs. Four male pigs of each breed, at proportionately 0·3 of their mature body weights, were randomly allocated to each of four diets in a cross-over design. The diets, which were formulated to contain similar levels of protein (ca. 160 g crude protein per kg) and energy (ca. 9 MJ metabolizable energy per kg), contained 0, 100, 200 and 300 g maize cob meal per kg, which corresponded to NDF levels of 276·4, 360·3, 402·9 and 523·5 g/kg dry matter, respectively. There was a negative correlation (P < 0·001) between the digestibility of OM, NDF, ADF and hemicellulose and the level of NDF in the diet. The digestibility of OM, NDF, ADF and hemicellulose decreased linearly (P < 0·05) with increase in the level of NDF among all three genotypes. There was a genotype × diet interaction on NDF and ADF digestibilities with digestibility in the LW decreasing faster (P < 0·05) than in the Mukota and LW × M F1 cross with increasing NDF. Both breed and level of maize cob meal affected N digestibility (P < 0·001), whilst the N retained per unit metabolic body weight was only affected by diet (P < 0·01). Increasing the level of maize cob meal beyond 100 g/kg, however, did not reduce N digestibility (P < 0·05). There was neither genotype nor dietary effect (P > 0·05) on N retained per unit N intake. These findings showed that the Mukota and the LW × M F1 cross were better able to digest the fibrous components than the LW. In addition, the Mukota and the LW × M F1 cross displayed an ability to retain protein to the same extent as the LW.
