Meat Type

Six adult male meat-type guinea pigs were subjected to three subsequent digestibility trials with 100% alfalfa, 50% alfalfa and 50% sugar cane and 50% alfalfa and 50% concentrate. For each animal in each period, feed intakes were recorded and all faeces were collected and stored at –20°C until analysis. Feeds and faeces were analysed for dry matter, crude ash, crude protein, ether-extract, crude fibre and acid-insoluble ash. Coefficients of apparent digestibility were calculated according to both the total collection method and the marker method with acid-insoluble ash as internal marker. The present study suggests that acid-insoluble ash is not valid as an internal marker when looking at differences between individuals, but might be useful to demonstrate differences between diets, albeit with lack of accuracy for estimating the absolute digestibility coefficients obtained through the total collection method. Sugar cane was slightly less digestible than alfalfa in meat-type guinea-pigs.

ABSTRACTObjective. Evaluate the effect of increasing P intake on nutrient digestibility, and compare the true and apparent absorption coefficients of P and Ca in lambs. Materials and methods. Twenty-four Santa Ines sheep, with an average weight of 33.6 ± 1.6 kg, were distributed into four treatments (0, 2, 4 and 6 g/day of supplementary P) with forage: concentrate ratio of 70:30. The study of apparent nutrient digestibility was conducted during the first week, using the total feces collection method. During the second week, after injection of 7.4 MBq of 32P and 7.7 MBq of 45Ca, apparent (AAC) and true (TAC) absorption coefficients of P and Ca were determined. The lambs were kept in metabolic cages. Results. The increase in P intake did not affect (p>0.05) dry matter, crude protein, NDF or ADF digestibility, but the TAC of P and Ca and mineral matter digestibility decreased. The AAC was not affected (p=0.10). A cubic relationship was observed between P intake and TAC (TAC=2.16–1.95X+0.55X2-0.04X3; R2=0.38) and linear relationship with the TAC of Ca (TAC=0.559–0.03X; R2=0.26). TAC and AAC values were different (p<0.001). Conclusions. The increase in P intake doesn’t impact organic matter digestibility, but does affect P and Ca absorption. Apparent digestibility is not a reliable parameter to determine the efficiency of P and Ca absorption.

Altogether 19 fodder climbers were collected with local information for their quality, feeding season and preference by livestock from Sunsari district, Nepal. Fodder climbers were distributed under 15 angiospermic families. Among them, 6 climber species were analyzed for dry matter, crude protein, ether extract, crude fibre, N-free extract, total ash and mineral contents (K, Ca, and P). Dry matter content ranged from 24.12 to 45.43%. Crude protein content showed slight variation. Ether extract ranged from 2.13- 4.23%, while Crude fiber content ranged between 18.62 and 22.52%. N-free extract showed narrow variation in the content while Total ash content exhibited a wide variation ranging from 5.67 to 11.52%. Among the minerals, Phosphorus showed distinct variation in the content from 0.19 to 0.46%. Fodder quality assessed by local people was compared with the result of chemical composition. On the basis of local information and chemical composition, Hedera nepalensis and Hedyotis scandens were considered as very good fodder climbers.

Phytochemical and nutritional potentials of various parts (leaf, stem and root) of Talinum triangulare were evaluated using standard techniques. Analysis of Variance (ANOVA) was employed in data analysis. All the parts of the species were found to contain nutrient compositions in varying levels. Dry matter and carbohydrate were highest in the stem (91.69±0.12 and 68.66±0.01) respectively. Moisture, ash content and crude fibre were highest in the root (9.78±0.04, 17.53±0.11and 15.32±0.03) respectively while ether extract and crude protein were highest in the leaf (1.09±0.01 and 17.72±0.17) respectively. The results showed also varying quantities of the phytochemicals in the leaf, stem and root with some parts lacking some of the phytochemicals. The leaf contained the highest percentage of all the phytochemical investigated alkaloid, flavonoid, tannin, sterol, Terpenoid, phenol and saponin (0.47±0.01, 0.26±0.00, 0.36±0.07, 0.03±0.01, 0.42±0.02, 0.02±0.01and 0.68±0.05 respectively. The root lacked sterol and phenol while stem lacked only phenol. The leaf, stem and root lacked cyanogenic glycoside. The results have indicated that these parts of the Talinum triangulare investigated are very nutritious and possessed bioactive compounds that could be extracted for the manufacture of new drug, food supplements and also be used in ethnomedicine for the treatment of diseases.

The proximate and mineral constituents of six plantain forms, raw green plantain (RGP), cooked green plantain (CGP), raw ripe plantain (RRP), cooked ripe plantain (CRP), green plantain meal (GPM) and ripe plantain meal (RPM) were determined by chemical analysis. 24 large white barrows, weighing initially, between 40-45 kg., were used to study the apparent digestibility of nutrients, digestible energy (DE), metabolizable energy (ME), metabolizable energy corrected for nitrogen retention (ME(n) and total digestible nutrients when the plantains served as the only source of nutrients. In a second experiment ME and ME(n) were measured for the plantain forms using 28 Large White barrows, with diets in which the plantains replaced 50% of maize in a basal diet. All the plantain forms had low fat, crude fibre and crude protein content but high in nitrogen-free extract, phosphorus, potassium and Iron. Identically high dry matter (D.M.) and nitrogen-free extract (N.F.E.) digestion coefficients were obtained for all the plantain forms except RPM, which had significantly lower values. Digestion coefficients for crude protein (46.9, 53.6, 51.8, 34.3,-32.7 %), crude fibre, (46.6, 49.5, 58.7, 62.6, 56.9, 39.6 %), ether extract (55.9, 56.6, 66.9, 69.2, 54.7 and 34.6 %) for RGP, CGP, RRP, CRP, GPM and RPM respectively were considerably lower than for D.M. and N.F.E. The DE, ME ME(n) and TDN values were comparable for all plantain forms except RPM, which had significantly lower values in most cases. The fresh green plantains and green plantain meals had slightly higher energy values than the ripe plantains, even though the nutrients in the ripe plantains were better digested than in the green forms. The results are discussed in relation to variations in the relative proportions of the simple and more complex carbohydrates during ripening.

Daily Feeding

Three trials with pregnant sows tied in stalls have been conducted to measure the effects on ration digestibility: (a) of a pelleted compound given once or twice per day, (b) of half the daily ration fed as barley at a separate time from the pelleted concentrate and (c) when the order during the day in which the barley and concentrate were fed was reversed.Giving pelleted complete rations twice as opposed to once per day led to slight improvements in the apparent digestibility of dietary dry matter, grpss energy, crude fibre and phosphorus. When half the daily ration was given as crushed barley in the morning the apparent digestibility of phosphorus was slightly higher than it was when barley was given in the afternoon. Nevertheless the apparent digestibility of dry matter and crude protein was greater for the complete mixture given twice per day. All these effects were statistically significant.

Modified Equation

The role of crude fibre in modifying the general equation relating the digestibility coefficient of crude protein to the percentage of crude protein in the dry matter of a feed is described.It is shown that for normal average food-stuffs the effect is slight and that for all practical routine purposes the original equation will provide satisfactory estimates of the digestibility coefficient when only the crude-protein content of the dry feed is known.On the other hand, when exceptional feeds are encountered, particularly those in which the crudefibre/crude-protein relationship is abnormal, then more accurate estimates of the digestibility coefficient of crude protein can be obtained from the modified equation which is described above.

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

Lactating Dairy Cows

Flaxseed hull, a co-product obtained from flax processing, is a rich source of n−3 fatty acids but there is little information on digestibility of its nutrients by dairy cows. Four rumen-cannulated multiparous Holstein cows averaging 665±21 kg of body weight and 190±5 d in milk at the beginning of the experiment were assigned to a 4×4 Latin square design with four 28-d experimental periods to determine the effects of feeding monensin and flaxseed hulls on total tract apparent digestibility of nutrients and fatty acids. The four treatments were: (1) diet CO: control with neither flaxseed hulls nor monensin added; (2) diet FH containing 19·8 g flaxseed hulls/100 g dry matter (DM); (3) diet MO with 16 mg monensin/kg DM; (4) diet HM containing 19·8 g flaxseed hulls/100 g DM and 16 mg monensin/kg DM. Diets provided similar amounts of protein and net energy of lactation. Digestibility of crude protein was higher for diets containing flaxseed hulls and for diets supplemented with monensin. Flaxseed hulls supplementation decreased digestibility of acid and neutral detergent fibre. Significantly higher digestibility of ether extract and individual fatty acids was observed for treatments with flaxseed hulls compared with treatments without flaxseed hulls. A combination of flaxseed hulls and monensin did not result in better fatty acid digestibility than when feeding only flaxseed hulls.

SummaryThe apparent digestibility coefficients of the various constituents of diets containing myristic, palmitic or stearic acids have been determined in an experiment with 8 sheep.The inclusion of myristic acid in the diet had no effect on the digestibility coefficient of total dry matter or crude protein, but it decreased the digestibility coefficients of crude fibre and nitrogen-free-extractives and increased the digestibility coefficients of fat and minerals. When palmitic acid was included in the diet there were decreases in the digestibility coefficients of total dry matter, crude fibre and nitrogen-free-extractives. The inclusion of stearic acid in the diet resulted in decreases in the digestibility coefficients of dry matter and nitrogen-free-extractives. There was an inverse relationship between the melting points and the digestibility coefficients of the added fatty acids.The findings of this investigation are discussed in relation to the results of a previous study on the effects of these dietary fatty acids on the yield and composition of cow's milk.
