This study hypothesized that reducing the level of crude protein (CP) in lambs′ feed may improve nutrient utilization and did not negatively affect their productive efficiency, blood metabolites, oxidative status (OS) or intestinal immune barrier function. A total of 120 weaned male Ripollesa lambs (45–60 days old and 15.0 ± 1.5 kg of body weight) were used. Four feed concentrates were formulated for two different phases (growing and finishing): CP20/19 group (20% and 19% of CP on dry matter basis, for each phase, respectively) and CP18/17 group (18% and 17% of CP on dry matter basis, for each phase, respectively). Lambs were randomly assigned to feeding treatments by balancing initial body weight between groups. The reduction of dietary CP level did not impair their growth performance parameters, while it did improve the apparent digestibility of organic matter. Furthermore, the lambs of the CP18/17 group showed lower plasma urea levels with no effect on OS (malondialdehyde levels) or gastrointestinal immunity markers (gene expression of interleukin 10 (IL10), tumor necrosis factor-α (TNFA) and transforming growth factor-β1 (TGFB)).

The aim of the study was to examine different pH parameters, such as variations throughout the day, depending on differing concentrate feed proportions. Moreover, special attention was payed to individual variation in microbial efficiencies (microbial crude protein/fermented organic matter) and their relation to ruminal pH, nutrient flows and digestibilities. For this, cows were grouped according to microbial efficiency (more, n = 5, vs. less efficient cows, n = 4). After calving, thirteen ruminally cannulated pluriparous cows, including nine duodenally cannulated animals, were divided into groups offered rations with a lower (35% on dry matter basis, n = 7) or a higher (60% on dry matter basis, n = 6) concentrate feed proportion. Ruminal pH parameters were assessed continuously by using intraruminal probes. Nutrient flows, nutrient digestibility and microbial efficiency were determined for duodenally cannulated cows. For most ruminal pH parameters it seemed that individual variability was higher than the treatment effect. However, a positive relationship between actual concentrate intake and diurnal pH fluctuations was found. Besides, the effect of individually different microbial efficiencies was assessed. Again, there were no group differences for pH parameters. However, nutrient flows were significantly higher in more efficient cows, whereas digestibilities were lower in in more efficient cows.

A research aimed to evaluate nutrients digestibility in growing local male pig fed spontaneous bioconverted-tamarind seed has been done in animal feed technology laboratory of Kupang State Agricultural Polytechnic.The research used 25 local male grower pigs with body weight around 3-6 kg. The study used a randomized block design with five treatments, i.e. R0 = ration using tamarind seeds without bioconversion, R1 = ration using spontaneous bioconversion tamarinds for 24 hours, R2 = rations using spontaneous bioconversion tamarinds for 48 hours, R3 = rations using bioconversion tamarinds spontaneous for 72 hours, and R4 = rations using spontaneous bioconversion tamarinds for 96 hours. Each treatment was repeated five times in which each of them used five pigs. Parameters observed were nutrient digestibility (dry matter, crude protein, crude fat, crude fiber, and ash). The data were analyzed by using variance and continued by Duncan’s multiple range test to determine the differences between treatments. The results showed that the time of spontaneous bioconversion of tamarind seeds increased the digestibility of tamarind seed nutrients and it was concluded that the best time of spontaneous bioconversion was for 72 hours.

Twenty female Jamunapari goats of live weight of 10.5 ± 1.2 kg at 08± 0.56 months of age were used for 240 days feeding trial. Goats were assigned to four dietary treatments in a completely randomized design with five (05) goats in each group. All animals were supplied ad libitum green grass and water. They were supplied 150, 200, 250, 300 gm concentrate mixture per day with roughage for group T1, T2, T3, and T4 respectively. Total dry matter (TDM) intake (413.2, 456.67, 489.2 and 495.7g/day) in groups T1, T2, T3, and T4, respectively, was significantly (p≤0.01) influenced by the level of concentrate in the diet. Average total digestible crude protein (DCP) intake (3.1, 3.5, 3.9, 4.0 g/kg body weight and average total digestible nutrient (TDN) intake 21.1, 22.3, 24.7, 25.1 g/kg body weight was significantly (p≤0.01) higher in group T4 and lower in group T1. The nutrient intake and digestibility were also significantly higher (p≤0.01) in T4 group. The percent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE) and nitrogen free extract (NFE) were 70.1, 75.99, 73.50, 67.24, 62.13 and 49.60%, 73.14, 76.97,76.84, 68.32, 64.04 and 53.25%, 75.45,78.44,78.67,70.43,68.43 and 59.77%, 79.56, 80.16,81.69,72.45,70.82 and 63.09% in T1, T2, T3 and T4 group, respectively. Reproductive performances, birth weight of kids and litter size did not differ significantly between groups, but had significant effect on feed digestibility and milk production. Daily 300 gm concentrate mixture along with roughage is necessary for better growth, production and reproduction performance of Jamunapari doe in semi-intensive system. Res. Agric., Livest.

The objective of this study was to evaluate the effect of inclusion of condensed tannins (CT) from black wattle (Acacia mearnsii) on feed intake, ruminal protozoa population, ruminal fermentation, and nutrient digestibility in Jersey steers. Five ruminally-cannulated steers were used in a 5 × 5 Latin square design, with five periods of 20 days each (14 days for diet adaptation and six days for sample collection per period). Treatments were composed of dietary inclusion levels of condensed tannins at 0, 5, 10, 15, and 20 g/kg of diet dry matter. Intakes of dry matter, organic matter, ether extract, crude protein, neutral detergent fiber, and total digestible nutrients were not affected by condensed tannins. The ruminal pH was reduced linearly with tannin levels. Ruminal ammonia nitrogen concentration was not affected by tannins. Tannins reduced the molar proportion of acetate and did not affect the ruminal protozoal population, which might be related to the low doses used. Digestibilities of dry matter, organic matter, and neutral detergent fiber were not altered; however, there was a linear reduction in crude protein digestibility. Based on these results, CT extracts from black wattle are not recommended for improving nutrient utilization in steers at the tested levels.

Abstract In recent years sheep, farming has emerged as an alternative production system especially in dry areas. The use of leaves and fruit from some trees has become an alternative for feeding for ruminants; however, studies on these species are scarce. The objective of this study was to evaluate the effect of S. spectabilis fruit meal on in vivo and in vitro digestibility, blood metabolites, and ruminal kinetics in hair lambs. This study was carried out at Las Brisas farm, University of Tolima - Colombia. Twelve male hair lambs with body weight of 20.3 ± 2.5 kg were used. Animals were distributed in an experimental 4x4 Latin square design. The treatments consisted of diets based on Dichanthium spp hay with different inclusion levels of S. spectabilis fruit meal (15, 30, and 45%). A linear increasing effect (P <0.05) was observed for in vivo and in vitro digestibility of dry matter, organic matter, and crude protein; likewise, plasma urea and ruminal degradability increased as the level of supplementation of S. spectabilis increased. The meal of S. spectabilis improves digestibility, protein intake, and ruminal kinetics in hair lambs; therefore, it is suggested as a promising alternative for ruminants feeding in dry tropic regions.

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.

Objectives This experiment was conducted to evaluate the effect of coat length and faecal hair removal on measured nutrient digestibility in longhair and shorthair cats. Methods A total of 14 adult domestic cats, with a mean ± SD body weight of 4.5 ± 1.21 kg and a mean ± SD age of 3.3 ± 1.38 years, were used for a nutrient digestibility trial. The nutrient digestibility of cats was measured by hair-included faeces and hair-removed faeces. Food was provided twice daily (09:00 h and 16:00 h) and water was provided ad libitum. Cats were adapted to a steel cage and diet for 16 days before a 10 day collection period. During the collection period, food offered, food refused and faecal output were measured daily and used for digestibility analysis. Results The digestibility of dry matter, crude protein and neutral detergent fibre (NDF) of longhair cats was underestimated by 8% ( P = 0.02), 9% ( P = 0.04) and 14% ( P = 0.04), respectively. In shorthair cats, the digestibility of dry matter, crude protein and crude ash increased by 4% ( P = 0.01), 5% ( P = 0.02) and 15% ( P <0.01), respectively, with hair-removed faeces. The nutrient digestibility between longhair and shorthair cats showed no difference when hair-included faeces were used. However, when using hair-removed faeces, the digestibility of NDF and amino acids in longhair cats were about 4–8% higher than in shorthair cats ( P <0.05). Conclusions and relevance This study showed that the nutrient digestibility values were affected by whether the hair in faeces was removed or not. Removing hair from faeces is a more precise method with which to evaluate the apparent nutrient digestibility of domestic cats.

Abstract The objective of this study was to investigate the effects of feeding levels on nutrient digestibility, rumen fermentation and blood metabolites of growing Korean native goats. Five growing bucks (19.5±1.4 kg) with an average age of 5 months were randomly allocated to one of five feeding levels [maintenance (M), 1.1 x M, 1.2 x M, 1.4 x M, and 1.6 x M]. The experimental design was 5 × 5 Latin square design and all animals were housed individual pens (1.2 m × 0.9 m) for an adaption period of 2 weeks and collection period for 1 weeks. Rumen samples were collected before morning feeding using oral stomach tube. Nutrient digestibility increased linearly in goat as feeding level increased (P &lt; 0.01), but body weight did not differ among feeding levels. Rumen pH and ammonia nitrogen concentration showed no significantly differences among feeding levels. The total and individual volatile fatty acids concentration increased linearly (P &lt; 0.01) and quadratically (P &lt; 0.05) with increased feeding levels. Blood metabolites did not differ among feeding levels. The fecal energy loss was not influenced by feeding levels, but digestible energy was increased linearly (P &lt; 0.01) and quadratically (P &lt; 0.05) with increased feeding levels. The metabolizable energy requirement was estimated using quadratic line model and ranged from 154 to 163 kcal per metabolic body weight based on average daily gain and ME intake. These results suggest that higher feeding levels of growing goat increases digestibility and nutrient utilization efficiency in the rumen. These results serve as a basis for the establishment of goat feeding programs at the farm scale in the Republic of Korea.

During the dry season, forages are low in quantity and quality; hence lacks the essential nutrients that are prerequisite for growth in ruminants, suggesting a supplemental feeding. Thus, this study was conducted to investigate the dry matter intake, nutrient digestibility and nitrogen balance in growing Red Sokoto bucks fed Sorghum bicolor hay supplemented with concentrate. Eight growing Red Sokoto bucks with average body weight of 15±1.0 kg were randomly allotted to two dietary treatments containing S. bicolor hay/concentrate mixture (100:0 and 60:40). The bucks were individually fed at 3.5% body weight daily for a period of 21 days in a completely randomised design with four replicates per treatment. The parameters measured were dry matter intake, water intake, amount of faeces voided, volume of urine and costs of feeding. Total dry matter intake (424.64g/day) was significantly (p<0.05) higher in 60:40 dietary treatment than 100:0 treatment (353.57g/day). The digestibility coefficients of crude fibre (92.34 %), acid detergent fibre (71.46 %) and neutral detergent fibre (69.77 %) were significantly (p<0.05) higher in Red Sokoto bucks fed Sorghum bicolor hay:concentrate ratio of 100:0 compared to bucks fed 60:40 diet with crude fibre (87.25 %), acid detergent fibre (59.67 %) and neutral detergent fibre (60.08 %) digestibility coefficient values. However, crude protein (78.49 %) and ash (70.04 %) digestibility coefficients in bucks fed 60:40 diet were significantly (p<0.05) higher than those fed 100:0 diet with 38.14 % crude protein and 21.45 % ash digestibility coefficients. There was an increasing trend (p<0.05) in all parameters measured when concentrate was supplemented. The nitrogen retained (7.55 g/day), nitrogen retained as % intake (68.76 %) and nitrogen absorbed as % intake (78.46 %) were significantly (p<0.05) higher in Red Sokoto bucks fed 60:40 diets when compared with that of 100:0 diet which recorded 0.69 g/day nitrogen retained, 23.87 % nitrogen retained as % intake and 38.15 % as nitrogen absorbed as % intake, respectively. Total costs per kg of feed (N78.13K) and costs of feeding per buck (N696.72K) were significantly (p<0.05) higher for 60:40 diet than 100:0 diet with N45.83K total costs per kg feed and N340.29K costs of feeding per buck. It is therefore, concluded that concentrate supplementation on Sorghum bicolor hay enhances its utilisation by growing Red Sokoto bucks in terms of increased dry matter intake, nutrient digestibility and nitrogen retention in Northern Guinea Savannah of Nigeria.

To evaluate the dietary inclusion of mesquite pods (Prosopis laevigata) on the growth performance, rumen fermentation, nitrogen balance, blood metabolites and carcass traits, 15 Creole goat kids (12.1 ± 2.8 kg body weight) were randomly assigned to one of three experimental diets with 0, 300 and 600 g of mesquite pods (dry matter basis). The study lasted 80 days. At the end of this period, the blood and ruminal fluid were sampled and the nitrogen (N) balance was calculated. The growth performance and feed intake were not affected by the mesquite pods. The nitrogen digestibility, N absorbed, and N retained increased linearly (P &lt; 0.05) with the increasing amounts of mesquite pods in the diet. The serum glucose and triglycerides were not affected by the mesquite pods, but the creatinine and uric acid decreased linearly (P &lt; 0.05) as the mesquite pods increased in the diet. The highest (P &lt; 0.05) rumen pH value, ammonia-N concentration, molar proportion of the acetate and the acetate : propionate ratio was found in the goat kids fed the diet with 600 g when compared to those fed diets with 0 and 300 g mesquite pods. Beneficial dietary effects of mesquite pods on the blood metabolites and N retention of the goat kids were found in this study; therefore, the dietary inclusion of mesquite pods at 600 g/kg can be used as a feed alternative for growing goat kids.
