Dry matter intake, nutrient digestibility and some rumen and blood metabolites were investigated in goats fed five diets composed of cassava peel and brewer's dried grains (BDG) in the ratios of approximately 82:8, 69:20, 57:33, 44:45 and 32:58. Urea and molasses were included in each diet at 2% and 7.5% respectively and the crude protein levels of the diets were approximately 8%, 11%, 14%, 17% and 20%. There were no significant (P > 0.05) differences in Dry matter and Organic matter intake but N intake Increased up to Diet 4. There were dietary effects on the digestibility of DM, N, crude fibre, acid detergent fibre, either extract, nitrogen free extract and energy but not 0M. The highest digestibility values were obtained on diet 4 for most of the nutrients. The concentrations of rumen ammonia and blood plasma urea increased from Diet 1 to Diet 5. There were significant (P < 0.05) dietary effect on rumen fluid ph. Rumen protozoal count increased from Diet 1 to Diet 5. The depression in digestibility of Diet 5 would indicate that BDG should not be included at up to 58% in the diet of goats.

<p>To investigate the effects of cassava peel-based diets on the meat composition of WAD goats, 24 five month-old goats were used for the experiment. Results show that the Dry Matter (DM), Crude Protein (CP) and Nitrogen Free Extract (NFE) content of the meat were not significantly (P&gt;0.05) different. The DM, CP and NFE content ranged from 29.96-30.00%, 89.77-90.43% and 2.00-4.03% respectively. The mineral composition revealed no significant (P&gt;0.05) differences in Iron (Fe), Calcium (Ca), Sodium (Na), Zinc (Zn), Magnesium (Mg), Potassium (K), Phosphorus (P) and Copper (Cu) content. The Fe, Ca, Na, Zn, Mg, K, P and Cu content ranged from 1.95-2.20mg, 23.65 -25.29mg, 72.86-77.05mg, 4.00-4.32mg, 55.65-57.83mg and 1.62-1.73mg respectively. From the results, it appears that cassava peels supplemented with sweet potato foliage could improve the meat composition of WAD goats.</p>

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

Lucerne (<I>Medicago sativa</I> L. var. Palava), harvested at four successive dates over a 30-day period, was evaluated for chemical composition (dry matter, organic matter, crude protein, ether extract, crude fibre, nitrogen-free extract, neutral detergent fibre, acid detergent fibre, acid detergent lignin), amino acid contents and intestinal digestibility in dairy cows. Dry matter (<I>r</I> = 0.78), organic matter (<I>r</I> = 0.95), crude fibre (<I>r</I> = 0.91), neutral detergent fibre (<I>r</I> = 0.94), acid detergent fibre (<I>r</I> = 0.79) and acid detergent lignin (<I>r</I> = 0.48) presented positive linear correlation coefficients (<I>r</I>) with growth stage, whereas crude protein (<I>r</I> = –0.96), ether extract (<I>r</I> = –0.86) and nitrogen-free extract (<I>r</I> = –0.70) showed negative relationships. Total essential amino acid content decreased (<I>r</I> = –0.94) from 84.1 to 55.3 g/kg of dry matter with maturity, with <I>r</I>-values higher than –0.90 obtained between growth stage and contents of lysine, methionine, threonine and valine. With the exception of tyrosine (<I>r</I> = –0.68), r-values between growth stage and individual non-essential amino acids were all higher than –0.90. Total amino acid (<I>r</I> = –0.98) and nitrogen (<I>r</I> = –0.99) contents presented comparable tendencies with successive sampling times. Whereas no definite trends were detected for the amino acid composition of rumen incubated (16 hours) lucerne samples, the intestinal digestibility of total essential (<I>r</I> = –0.78), total non-essential (<I>r</I> = –0.58) and total (<I>r</I> = –0.69) amino acids as well as nitrogen (<I>r</I> = –0.99) decreased with growth. However, due to a small sample size (<I>n</I> = 4), most linear relationships between constituents and growth stage were insignificant. It can be concluded that, although limited in the sample size, this report presents information on the decrease in amino acid contents and intestinal amino acid digestibility as growth proceeds in lucerne (var. Palava) produced in the Czech Republic, which could be utilized in the feeding of ruminants.

1. Germ-free (GF) and conventional (CV) rabbits wearing collars to prevent coprophagy were fed an autoclaved diet with added cellulose. Their faecal excretion was analysed to determine nutrient digestibility.2. Clearly distinguishable hard faeces were excreted by the GF rabbit only if the diet contained at least 15% cellulose. Unlike CV rabbits, the GF rabbits did not consume their soft faeces even when permitted to do so. Soft faeces made up a larger proportion of the total output of GF than of CV rabbits. Food intake and total dry-matter excretion per kg body-weight were similar in both groups.3. Although digestibility of dry matter was similar in the two groups, in the GF rabbits there was a higher digestibility of crude fat and true protein and a lower digestibility of crude fibre and nitrogen-free extract. GF rabbits excreted a higher percentage of ingested calcium and phosphorus in the urine than did CV rabbits.4. The results suggest that intestinal microbes, even without the enhancing effect of coprophagy, aid in the digestion of carbohydrate by rabbits. The greater faecal excretion of crude fat and true protein by CV rabbits could result from poorer digestion and absorption, but could also represent nutrients synthesized by microbes from simpler materials. The reingestion of faecal crude fat and true protein might therefore improve the quality of the total nutrient intake. The results suggest ways of assuring an adequate dietary intake by GF rabbits in the absence of contributions from an intestinal microflora.

The study was conducted to evaluate the effect of polyenzyme treated corn cob based diet on the dry matter acceptability and nutrient digestibility by West African dwarf rams. Sixteen (16) rams were used in a completely randomized design, comprising of 4 per treatment in metabolic cages for digestibility while for acceptability each animal was allotted to a pen and the cafeteria feeding method employed. The dietary treatments were: T1 (cassava peel untreated); T2 (corn cob untreated); T3 (polyenzyme treated cassava peel) and T4 (polyenzyme treated corn cob) respectively. The result for dry matter acceptability showed that T3 had the highest value for dry matter intake (979.20g/h/d); coefficient of preference (1.06) and percentage of preference (26.44%). Significant (p<0.05) difference were obtained for the digestibility percentages of all the proximate nutrients. The digestibility values recorded for T3 was the highest (P<0.05) for DM (78.81), CP (81.91), CF (70.24), EE (37.40), NEF (80.05), NDF (76.99) and ADF (71.69). However, it is recorded that inclusions of polyenzyme to cassava peel and corncob have a promising acceptability, enhanced and efficiently utilized by sheep. The study shown that treatment of cassava peels and corn cob with polyenzyme improved and sustain ruminants during period of feeds insufficiency. Also, provide a better utilization of wasteful cassava peel and corn cob to feedstuff so as to improve farmers that practice intensive ruminant management.

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.

This study focuses on the determination of apparent digestibility of pasture vegetation nutrients in horses of the Old Kladruber breed through a balance indicator method (determination of acid insoluble ash). When evaluating the nitrogenous substances, their determination was based on the content of pure protein (sum of amino acids) which is more accurate than crude protein. There were differences in the chemical composition of dry matter from pasture vegetation and horse excrements. Regarding crude fat, crude fibre, acid detergent fibre, neutral detergent fibre, acid detergent lignin, ash, P and Mg, the average values in dry matter of horse excrements were significantly (P≤ 0.01) higher; on the contrary, we found significantly (P≤ 0.01) lower mean values of nitrogen-free extract, organic matter and Ca ​​in the dry mass of pasture grass. The highest coefficient of apparent digestibility for organic nutrients was determined in the nitrogen-free extract (73%) followed with organic matter (71%), pure protein (68%), crude protein (65%) and crude fat (61%). In case of fibre and its fractions, the apparent digestibility coefficients decreased as follows: crude fibre (66%), neutral detergent fibre (66%), acid detergent fibre (63%) and acid detergent lignin (42%). Significantly lower values were determined for coefficients of apparent digestibility for minerals P (16%) and Mg (50%), which highlights the need for their regular supplementation in horses on pasture. This study extends the current state of knowledge regarding the apparent digestibility of pasture vegetation which is a prerequisite for optimal nutrition of horses.

Chemical compositions of ensiled cassava peels, dried cassava peels and gliricidia on the performance of West African Dwarf sheep were evaluated. Twelve grower rams and ewes between 5-7 months of age were allotted to three treatment diets: D1 (control) diet was 100% gliricidia (GLI) (leaves with bark and soft stem), D2 consisted of 80% ensiled cassava peels plus 20% gliricidia (ENP/GNI) while D3 consisted of 80% dried cassava peels plus 20% gliricidia (DP/GLI). The three test feeds were observed to have more comparable crude fibre contents ranging from 16.07% for ensiled cassava peels to 18.20% for gliricidia. The gross energy values were also comparable ranging from 3.93kcal/gDM for ensiled cassava peels to 4.64kcal/gDM for gliricidia. Gliricidia was however observed to be richer in crude protein and minerals compared to ensiled cassava peels and dried cassava peels. Dry matter intakes, dry matter digestibility and growth rates showed significant (P<0.05) differences with the tilt being in favor of the animals fed on the sole glricidia diet. The energy digestibility of 79.83% for the animals fed on ensiled cassava peels and gliricidia diet was not significanyly (P>0.05) different from the corresponding value of 82.67% observable for animals fed on the sole gliricidia diet. Both values  were however significantly higher (P<0.05) than the values of 74.17% obtained for animals on the dried cassava peel plus gliricidia diet. Feed conversion values showed no significant (P>0.05) differences for the three groups ranging from 8.8. (ENP/GLI) to 10.80 (DP/GLI). Cassava peels supplemented with gliricidia can be used in practical production diets for West African Dwarf sheep with better prospects of utilization through ensiling of the peels.

The nutritive value ,voluntary dry matter intake, and the nutrient digestibility of graded levels of Gmelina arborea and cassava peels concentrates in WAD sheep was investigated. Twelve WAD sheep aged 1-2 years old and weighting 14.00± 0.45 kg were used in a complete randomized design. Diets were formulated such that cassava peels was replaced with Gmelina arborea leaf meal at 0, 33.33, 66.67, 100% levels, designated as diets A, B, C, and D respectively. Diet without Gmelina arborea leaf meal was tagged the control diet. The concentrate feed was compounded to contain 16% CP. Diets with 33.33% inclusion level of Gmelina arborea had significantly (P<0.05) higher dry matter intake (DMI) 598.80g day-1, while the lowest DMI 425.00g day-1 was obtained in animals fed 100% inclusion level of Gmelina arborea. Crude protein intake (CPI) of animals fed diets with 33.33% inclusion levels of Gmelina arborea were significantly (P<0.05) highest, followed by 66.67% inclusion level and the least was observed in 0% inclusion level of Gmelina arborea. Dry matter digestibility (DMD) was significantly (P<0.05) different across the dietary treatments, animals placed on diets with 33.33% inclusion level had the highest DMD, followed by animals on diets with 66.67, 100 and 0% inclusion levels. CP digestibility (P<0.05) increased from 33.33% to 100% inclusion levels of Gmelina arborea leaf meal, the lowest CP digestibility was observed at 0% inclusion level. CF digestibility (P<0.05) increased from 33.33% to 100% inclusion levels of Gmelina arborea leaf meal, while the lowest CF digestibility was observed at 0% inclusion level. N intake increased significantly (P<0.05) with increase in the level of Gmelina arborea inclusion from 33.33% to 100%. N retention was significantly (P<0.05) different, diets with 33.33% Gmelina arborea inclusion had the highest value (64.36g day-1) followed by 66.67%, 100% and the least (52.64g day-1) was at 0% inclusion level of Gmelina arborea.  N balance values also followed the same trend. From the results of this study, it can be concluded that the inclusion of Gmelina arborea leaf meal in WAD rams diet was well tolerated without adverse effect on acceptability, intake and nutrient digestibility, and inclusion level of 33.33% is hereby recommended in ruminants diet for optimum performance and productivity.

Abstract A study was conducted to evaluate effects of increasing concentration of food grade glycerol on rumen environment and nutrient digestibility. Three ruminally cannulated Jersey steers were used in this study. The study was conducted from March to May 2019. Experimental design was a 3x3 Latin square with a 2wk adjustment period followed by a 1wk collection period. Diet was coastal bermudagrass hay based. Different forage types were introduced in the incubation process to evaluate digestibility. Glycerol was administered once a day at 0, 15, or 20% of DMI (dry matter intake). dNDF (digestible NDF) and dDM (digestible dry matter) was determined using an ANKOM Daisy II incubator inoculated with 200g fresh rumen fluid and incubated for 12, 24, 48 and 72 h at 39°C. Each vessel contained ground forage samples in filter bags in triplicate. After incubation, filter bags were rinsed with cold water and dried for 24h in a 55°C forced air oven. Data were analyzed using the Proc MIXED procedure of SAS version 9.4. There was no difference dNDF in effect of different levels of glycerol between forage types by diet. But a numerical tendency was observed that dNDF was decreased at 20% inclusion rates in comparison to 0 and 15% inclusion of glycerol in the diet. Neither steer nor run was significantly different in the study. However as expected digestibility over time was significantly different (P &lt; 0.001). A significant increase was observed in DMI with the increased levels of glycerol in the diet (P = 0.003), both the 15% and 20% levels of glycerol increased in DMI in comparison to the control (0%). It appears based on these study results that digestibility may be inhibited, as levels of dietary glycerol increase in the diet and more work needs to be done to find the optimal level of glycerol supplementation.
