Cassava 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.

Lactating Cows

The aim of this study was to determine the best level of utilization of dried waste of cassava starch extraction (WCSEd) as a substitute for corn for lactating cows. Four lactating cows were fed diets with increasing levels (0%, 33%, 66% and 100%) of WCSEd as a substitute for corn. The intake and digestibility of dry matter and nutrients, milk production and composition, blood parameters of glucose and urea and microbial synthesis of the diets were evaluated. There was a reduction in dry matter intake, organic matter, ether extract and total carbohydrate, and increased intake of acid detergent fiber. Nutrient digestibility was not affected while the synthesis of microbial protein increased. These changes resulted in reduced milk production, without altering the efficiency of production or the constituents of milk, with a decreasing effect on daily production of lactose, solids and minerals. Metabolic parameters, glucose and urea nitrogen in plasma, remained within appropriate levels. The dried residue from the extraction of cassava starch can be used as feed for dairy cows to replace up to 100% of the corn ration. However, its use promotes a reduction in intake of dry matter and nutrients as well as a reduction in the production of milk, with impacts on the profitability of the product.

Abstract The objective of this study was to evaluate the growth performance and apparent total tract nutrient digestibility of Holstein heifers limit-fed diets containing different amounts of wet brewer’s grains (WBG). A 12-wk randomized complete block study was conducted using 30 yearling Holstein heifers [378 ± 27 d of age, and body weight (BW) of 357.8 ± 27.6 kg (mean ± SD)]. Treatments were 0%, 10% and 20% of WBG on a dry matter (DM) basis and diets were formulated to be limit-fed for dry matter intake (DMI) at 2.35% of BW and provided 15% crude protein (CP) and 2.27 Mcal metabolizable energy/kg of DM. Dry matter intake was recorded daily, while BW and skeletal measurements were measured every 2 wk. During week 12, fecal samples were collected directly from the rectum over four consecutive days and composited by heifer to determine apparent total tract nutrient digestibility using acid detergent insoluble ash as a marker. Data were analyzed using the MIXED procedure of SAS. Dry matter intakes, BW, and average daily gain were not different among treatments (P = 0.2, P = 0.4, and P = 0.6, respectively). Dry matter intakes ranged from 8.6 to 9.0 kg/d. Average BW were 404.4, 411.5, and 409.3 kg for heifers fed the 0%, 10%, and 20% WBG diets, respectively. Average daily gains were 1.03, 1.04, and 0.96 kg/d for heifers fed the 0%, 10%, and 20% WBG diets respectively. Skeletal measurements and body condition scores (BCS) were not different among treatments except for the change in heart girth (P &lt; 0.01) and initial BCS (P &lt; 0.01). Apparent total tract digestibilities of DM, organic matter, CP, fat, and hemicellulose were greater or tended to be greater in heifers fed 0% and 20% WBG treatments than heifers fed 10 % WBG (P = 0.04, P = 0.04, P = 0.06, P = 0.06, and P = 0.01, respectively). Neutral detergent fiber, acid detergent fiber, and fat digestibilities were similar among treatments (P = 0.2, P = 0.3, and P = 0.3, respectively). During the digestibility phase, DMI tended to be greater (P = 0.08) for the 10% WBG treatment. These results demonstrate that limit-feeding heifers with diets containing up to 20% WBG could replace soybean- and corn-based concentrates in diets without adverse consequences to the heifer growth performance.

Abstract Objectives of this study were to evaluate apparent total-tract nutrient digestibility and purine derivative (PD) excretion in dairy heifers limit-fed diets containing wet brewer’s grains (WBG) treated with salt. A 12-wk replicated 4×4 Latin square was conducted using 8 Holstein heifers of 224.5 ± 19.4 d of age, and body weight (BW) of 219.2 ± 28.1 kg (mean ± SD). Fresh WBG were treated with 0%, 0.8%, 1.6%, and 2.4% salt and stored for 4 d before being fed. Salt was added either to the WBG or separately to equalize the amount of salt in the diet. The diet contained 9% grass silage, 47% corn silage, 19% corn meal, 17.6% WBG and salt, 2% soybean meal (SBM), and 3% mineral mix. Diets were formulated to be limit-fed at 2.15% of BW, provide 14% crude protein (CP) and 2.27 Mcal metabolizable energy (ME)/kg of dry matter (DM). Heifers were adapted to diets for 14 d followed by a 7-d collection period. Dry matter intake (DMI) was recorded daily during the collection week while BW was recorded once a week. Urine and fecal samples were collected during the last 4 d of the collection period. Acid insoluble ash was used as an internal marker to determine apparent nutrient digestibility. Weight loss of WBG during storage was determined from d 1 to d 11 and initial and final yeast and mold counts were determined. Final yeast counts were similar among treatments while final mold counts tended to be lesser (P = 0.07) for the 0.8 and 1.6% salt treatments. Urinary volume was similar among treatments while allantoin (P = 0.14), and uric acid (P &lt; 0.01) and total PD excretion tended to increase (P = 0.13) quadratically. Dry matter intake was varied by treatment (linear, quadratic, and cubic effects P &lt; 0.01). Heifers fed the 0.8% treatment had the least DMI. Non-fiber carbohydrate (NFC) digestibility linearly decreased (P &lt; 0.04) as salt increased. Digestibilities of DM, and organic matter (OM), tended to decrease (P &lt; 0.10) with increasing levels of salt added to WBG. Fat digestibility was quadratic with the greatest value for the 1.6% treatment. Treating WBG with salt reduced its deterioration based on lesser mold counts for the 0.8 and 1.6% treatments. These treatments had resulted in greater fat digestibility and tended to have increased PD excretion suggesting improved microbial protein synthesis.

Four Red Sokoto bucks of averageweight 17. 40±2kg were fed sugarcane scrappingmeal in a complete diet to evaluate the nutrients intake, digestibility and nitrogen balance. In a 4×4 Latin Square Design four dietary treatments containing sugarcane scrapping at 0, 10, 20, and 30% levels of inclusion supplementing wheat offal in a complete diet were used The proximate composition of the sugarcane scrapping showed that the scrapping had, 10.01, 2.98%and 3114 Kcal/Kg of CF, CP andME respectively. The results of the trial showed that significant high dry matter intake, nutrient digestibility of some and the nitrogen balance values were recorded in the bucks fed 30%. It was concluded that DM intake, nutrient digestibility and nitrogen utilization of bucks can be enhanced by including 30% of sugar cane scrapping in their diets.

A study on effect of ensiled maize stover (EMS) and protein concentrate supplement (CS) on nutrient digestibility and nitrogen balance of ensiled maize stover (EMS) and concentrate supplement (CS) by West African Dwarf ewe was carried out. were showed Fifteen West African dwarf ewe with body weight of 14-16 kg allotted to individual metabolic cage in completely randomized design after preliminary feeding trial. The treatments were: A (75% EMS + 25% CS), B (50% EMS + 50% CS), C (25% EMS + 75% CS), D (100%EMS) and E (100% CS). The digestibility study lasted for seven days to determine dry matter digestibility, nutrients digestibility and nitrogen retention of WAD ewe fed ensiled maize stover and concentrate supplement. Results that dry matter intake (DMI), digestible crude protein (DCP), digestible crude fibre (DCF), digestible nitrogen free extract (DNFE), and total digestible nutrients (TDN) ranged from 321.65- 694.41gDM/day, 3.99 - 12.30%, 7.32 - 17.23%, 33.35 – 38.85% and 63.65 – 70.92%, respectively. Dry matter intake of ewe fed sole ensiled maize stover (diet D) was lowest (321.65gDM/day) while animals on diet C (25% EMS+75%CS) had the highest (694.41gDM/d). Apparent digestibility of CP was lowest (3.99%) in ewe fed sole EMS and highest (12.20%) in ewe fed diet C (25% EMS + 75% CS). Positive N-balance was observed for all the five diets, but it was highest (P< 0.05) in diet B (50%+50%) and lowest in diet D (100% EMS). Similarly, N-retention was highest (67.15%) in diet B and lowest (27.61%) in diet D. Therefore, diet made up of 50% ensiled maize stover and 50% concentrate is recommended for sheep production.

Four Holstein-Friesian crossbred dairy cows were randomly assigned according to a 2 × 2 factorial arrangement in a 4 × 4 Latin square design to study the effect of banana flower powder (BAFLOP) and sodium bicarbonate (NaHCO3) supplementation as rumen-buffering agents on rumen fermentation and milk production. The first factor was two ratios of roughage to concentrate (R : C) at 60 : 40 and 40 : 60, whereas the second was two sources of buffering agent (BAFLOP and NaHCO3) supplemented at 20 g/kg of dry matter intake. All cows were fed total dry matter intake at 25 g/kg bodyweight and untreated rice straw was used as a roughage source. Feeding R : C at 40 : 60 increased nutrient digestibilities, nitrogen absorption, allantoin excretion and absorption, microbial nitrogen synthesis, microbial crude protein and efficiency of microbial nitrogen synthesis in both BAFLOP- and NaHCO3-supplemented groups. BAFLOP supplementation could maintain ruminal pH as NaHCO3. Blood urea nitrogen, total volatile fatty acid and propionate, and milk yield increased in cows fed R : C at 40 : 60 both in BAFLOP and NaHCO3 supplementation, whereas acetate was relatively high in cows consuming R : C at 60 : 40. However, rumen microorganisms were similar among treatments whereas milk compositions were unchanged by the dietary treatments, except milk fat and total solids were the highest in cow consumed R : C at 60 : 40. The results suggested that feeding R : C at 40 : 60 resulted in improvement of nutrient digestibility, rumen fermentation efficiency and milk production, and supplementation of BAFLOP showed similar buffering capacity as NaHCO3. Therefore, BAFLOP could be used efficiently as a dietary rumen-buffering agent and promisingly deserves a replacement for bicarbonate sources in lactating dairy cows fed on a high concentrate diet.

An experiment was conducted to determine the effect of feeding concentrate diets containing varying levels of groundnut haulms on dry matter intake, nutrient digestibility and nutrient balance in Friesian x Bunaji bulls. The feed consisted of four concentrate mixed diets formulated to contain on average 14.45- 14.65% crude protein. Groundnut haulms (GH) in the concentrate diets were on nitrogen basis at 0, 25, 50 and 75% levels with control diet having 0% inclusion of GH. Sixteen bulls aged 12-18months were divided into four each and were randomly allotted to the four treatment diets in a completely randomized design for metabolic trial. During trial, the bulls were housed in metabolic crates and fed Gamba hay adlib and the basal or particular test concentrate mixture at 40% of estimated DM intake. Chemical composition and energy contents of the diets were determined. Dry matter intake (D M ) and organic matter intake (OMI) were also determined. The CP value averaged 14.45±0.44 - 14.65±1.22% for the four experimental diets. The metabolizable energy content expressed in Kcal/kg of diets decreased with increase in GH level from 0-75% (3166-1752 kcal/kg). There was no significant (P>0.05) difference on voluntary DMI and OMI. The digestibility coefficients of DM, OM, CP, CF, EE, NDF, ADF, hemicellulose and ash were significantly (P<0.05) higher at 75% level of groundnut haulms. CF and ADF digestibility were significantly influenced (P<0.05) when groundnut haulms level reached 25%. Conversely, the digestibility of NFE did not differ (P>0.05) across treatments. Nitrogen balance were similar (P>0.05) among animals fed concentrate mixtures. Nitrogen balance expressed in percent was slightly higher at 75% level of groundnut haulms. It is concluded that inclusion of GH in concentrate diets of crossed bulls up to 75% can improve nutrient digestibility and the percent Nitrogen balance.

The Difference

Pangolagrass (Digitaria decumbens) and stargrass (Cynodon nlemfuensis) harvested at 30, 45, and 60 days and made in to hay, were fed to four castrated male ruminants (goats and steers) in individual digestion stalls. The grasses were fertilized at the rate of 4,480 kg/ha/yr with 15-5-10, harvested, sun-dried for 2 days and cut in 3- to 6-cm pieces. Each experimental period lasted 21 days, divided into a 14-day preliminary feed ing period and a 7-day collection period. Each hay was offered at a level of 90% intake, as determined in the preliminary period. Hays, offered and refused, and feces were weighed and sampled daily. Representative samples were analyzed for dry matter, crude protein, neutral-detergent fiber, acid-detergent fiber, cellulose, lignin, and silica. Hemicellulose was determined as the difference between neutral-detergent fiber and acid-detergent fiber. Apparent digestion coefficients for each fraction were calculated on all hays and all ruminants. Pangolagrass dry-matter intake was significantly (P < .01) greater than that of stargrass hay by both goats and steers. No significant differences in dry-matter intake were obtained between hay ages of 30, 45, and 60 days. Goats had a higher dry-matter intake (P < .01) than steers. Significant differences were obtained between hays in neutral-detergent fiber (P < .01), hemicellulose (P < .01), and cellulose (P < .05) contents and between hay ages in crude protein (P < .05), cellulose (P < .01), lignin (P < .05), and silica (P < .01) contents. For digestibilities, significant differences were obtained between hays in dry matter (P < .05), neutral-detergent fiber (P < 05), and cellulose (P < .01); between hay ages in lignin (P < .01) and silica (P < .01); and between ruminants in dry matter (P < .01), neutral-detergent fiber (P < .01), acid-detergent fiber (P < .01), hemicellulose (P < .01), and cellulose (P < .01). Goats may not necessarily substitute for steers in digestion trials; and lignin, but not silica, tends to be a valid marker for determining digestibility.
