ABSTRACT Oilseed grains are used as a protein and energy source, increasing the energy density of the feed. The goal of the present study was to determine the nutritional profile of canola, crambe and soybean grains recovered from feces, and to evaluate the intake and digestibility of nutrients, rumen fermentation parameters of beef cattle receiving whole grains of oilseeds. Three steers, 350 ± 23.5 kg body weight were distributed in a not contemporary, 3 × 3 double Latin square, and fed oilseed grains. Inclusion of crambe grain reduced dry matter intake by 21.02%, with a higher digestibility coefficient for EE and NDF. The crude protein content of canola and crambe grains recovered were similar, but the EE content was higher for the crambe grain (26.46%). Soybean showed the lowest values of chemical composition for grains recovered from feces. The highest dry matter intake (7.86 kg/day), and the lowest NDF digestibility (0.203g/kg), were found for animals fed soybean. The inclusion of crambe grains reduced the rumen ammonia content (10.97 mg/dL); however, the ruminal pH was not altered by the inclusion of grains in the diet. Canola and soybean grains can be included in the cattle diet without altering dry matter intake; while the inclusion of crambe grains reduces the dry matter intake and the ruminal ammonia content of the animals. Crambe grain showed the highest recovery of dry matter and ether extract from feces.

A trial involving a 2x2 factorial design was conducted to evaluate the effect of corn silage hybrids and concentrate levels (25 and 50%) on intake and digestibility of nutrients, ruminal characteristics and microbial efficiency in steers. Four ruminal and abomasal cannulated steers (512±25kg of birth weight), were used in a 4×4 Latin square design. Treatments consisted of 75% silage A + 25% concentrate; 50% silage A + 50% concentrate; 75% silage B + 25% concentrate; and 50% silage B + 50% concentrate on dry matter (DM) basis. There were no differences in the intakes of DM, organic matter (OM), crude protein, and ether extract. The intake of non fiber carbohydrates and total digestible nutrients were positively affected by concentrate levels. The digestibility of DM and OM were also positively affected by concentrate levels. There were no effects of treatments on ruminal pH values, ruminal ammonia-N, and microbial efficiency.

Abstract The aim of this study was to investigate the consequences of the fat supplementation source (free oil and rumen-protected fat) on the nutrient intake and digestion of beef cattle at pasture. Five rumen-cannulated Nelore bulls, with an average 467.8±32.8 kg of body weight (BW) and age of 26 months, were distributed in a Latin square design (5 x 5). The treatments were as follows: WF: without fat, PS: rumen-protected fat soybean oil, PA: rumen-protected fat palm oil, SO: soybean free oil, and CO: corn free oil. Nutrient intake and digestibility, ruminal pH and ammonia (NH3-N), serum urea, and nitrogen balance were analyzed. The supplements with different fat sources did not alter (P>0.05) the intake and digestibility of dry matter (DM), forage, organic matter (OM), crude protein (CP), neutral digestibility fiber (NDF), neutral digestibility corrected ash and protein (NDFap), nonfiber carbohydrates (NFC) or total digestible nutrients (TDN), except ether extract (EE). An increase (P<0.05) in the intake and digestibility was observed with the inclusion of a fat supply, independent of the fat source. Differences were observed between the WF and other supplements with regard to ruminal parameters (pH and NH3-N) (P>0.05) and serum urea (P>0.05). The nitrogen balance was not affected by the fat source (P>0.05). Supplementation of grazing beef cattle with 2 g/kg BW low-level free oil (130 g/kg DM supplement) or rumen protection (160 g/kg DM supplement) did not interfere with the characteristic nutrient intake and digestibility.

ABSTRACT Here in this study we assessed dairy heifers kept in tropical grasslands during spring and summer seasons to observe the effects of two supplementation strategies upon their performance. Sixteen dairy heifers (Holstein 5/8 x Gyr 3/4) with 135.25 kg of body mass were randomly assigned in two supplementation treatments (e.g., mineral salt and protein salt supplement) during spring and summer seasons, divided into two groups of eight animals that represented 4.29 animal unit ha. Initial and final fasted weights (i.e., feed and water withheld for 16h) were obtained before to start and at the end of each grazing cycle (28 days), and then the weight gain (kg animal-1) per grazing cycle was calculated by the difference between final and initial weights. There was no significant effect (P <0.05) on the intake of dry matter, crude protein, ether extract, neutral detergent fiber, and dry matter digestibility, between treatments (P <0.05). However, there was a significant effect (P <0.05) between seasons; e.g., respective means of dry matter intake (kg day-1,% BW g / kg 0.75), intake of crude protein (g day-1 g / kg 0.75), ether extract (g day-1), neutral detergent fiber (g day-1 and% BW) were 3.95 and 2.88 kg, 2.54 and 1.65%, 89.27 and 59.56 g kg0.75, 429.89 and 298.43 g day-1, 9.72 and 6.18 g kg0.75, 118.79 and 84.07 g day-1, 2.90 and 2.05 kg day-1, 1.86 and 1.18%, for Spring and Summer seasons. Moreover, the dry matter intake (% BW and g kg 0.75 of DM) were higher (P < 0.05) during the spring season (e.g., 2.53 vs 1.64 % BW; and 89.26 vs 59.56 g kg0.75 DM).

The objective of this study was to evaluate the inclusion rate of pea hay in barley or oat hay diets for beef cattle. Six ruminally cannulated heifers (407 ± 38 kg) were used in a 6 × 6 Latin square (25 d periods) with a 2 × 3 factorial design. Treatments included whole-crop barley or oat hay with pea hay blended in to achieve inclusion rates of 0%, 15%, or 30% (dry matter basis) of the forage. Pea hay inclusion increased dry matter intake (DMI; P = 0.03) by 0.75 kg d−1 relative to diets without pea hay, but the response was not linear or quadratic. Inclusion of pea hay linearly increased mean ruminal pH (P = 0.039), the concentration of butyrate in ruminal fluid (P = 0.013), plasma urea nitrogen (N) concentration (P = 0.001), and quadratically increased ruminal ammonia concentration (P < 0.001). Pea hay inclusion reduced crude protein (CP) digestibility by 2.87% relative to cereal-only treatments (P = 0.025), but did not affect N intake, microbial N, or N excretion. Overall, pea hay inclusion increased DMI, increased ruminal butyrate concentration, but reduced CP digestibility without affecting N balance.

<p>This study aimed to evaluate nutrient intake and digestibility by sheep fed diets containing residue from the extraction of tamarind pulp (RETP). We used four sheep with a mean body weight (BW) of 40.38 kg, whose pens were distributed in a Latin square design. The diet treatments contained 0, 5, 10 and 15% of RETP. The variables were subjected to analysis of variance and the differences observed were tested using regression equations at 5% significance. The intake of dry matter (DM), organic matter (OM), crude protein (CP), total carbohydrates (TC), and non-fiber carbohydrates (NFC),expressed in g day-1, % BW and g kg0,75-1, were not significantly affected (p&gt;0.05) by the inclusion of RETP. The intake of ether extract (EE) and neutral detergent fiber (NDF) showed a linear increase (p&lt;0.05) as RETP content rose. However, the digestibility of DM, CP, TC, and total digestible nutrients (TDN) decreased linearly (p&lt;0.05), while the digestibility of EE, NDF, ADF, and NFC, with average values of 62.12%; 79.95%; 41.59%; 37.12%, and 91.57%, respectively, were not significantly affected (p&gt;0.05) when RETP was included in the diet. The inclusion of up to 15% of the residue from the extraction of tamarind pulp changes the intake of ether extract and neutral detergent fiber, and reduced dry matter, crude protein, and total carbohydrates in the sheep’s diet.</p>

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.

Twelve male growing lambs were used in a randomized complete block design to determine the effects of feeding liquid acid whey (LAW) on the performance of the animal, its dry matter intake, nutrient digestibility, weight gain and ruminal pH. Animals received a diet consisting of Napier grass (Pennisetum purpureum, Schumacher). Treatments were Napier grass plus concentrate, Napier grass plus LAW and Napier grass plus concentrate plus LAW. Individual dry matter intake (DMI), biweekly weight gain (WG) and ruminal pH were measured. Diet digestibility was determined using the total collection method. Results showed that LAW increased (p<0.05) WG and diet digestibility (dry matter, organic matter and crude protein). Liquid acid whey had an average digestibility of 54.41% for dry matter, 83.94% for organic matter and 87.56% for crude protein. Ruminal pH two hours after feeding was stable for animals with LAW alone. However, DMI was similar (p>0.05) among treatments. It can be concluded that including LAW in the diet significantly improved WG, diet digestibility and ruminal pH without affecting DMI.

ABSTRACTObjective. To evaluate the effect of three energy sources on the intake, total apparent digestibility and excretion of nutrients in cattle diet. Materials and methods. Six ruminally cannulated cows (730 ± 70 kg) were distributed into three treatments in a replicated 3x3 Latin square experimental design, where: (I) Control: Low ether extract diet (3.50% EE); (II) Soybean: High ether extract diet (5.30% EE) with inclusion of 15% soybean and (III) Citrus pulp: Low ether extract diet (3.00% EE) and high pectin involvement with inclusion of 15% citrus pulp. To determine the digestibility of DM and its fractions, chromic oxide was used as a marker. Nutrient excretion was calculated from the digestibility coefficient of each fraction. Results. The soybean treatment reduced (p<0.05) dry matter, crude protein, nitrogen-free extract and organic matter intake and increased ether extract intake. There was no effect (p>0.05) of the energy source on the digestibility coefficients of DM, CP, NDF, EE, NFE or OM. The TDN value was higher for the soybean treatment. The excretion of DM, NFE and OM was lower (p<0.05) for the soybean treatment. All energy sources influenced the excretion of crude protein. Conclusions. The energy sources used did not affect the digestibility of the diets and are indicated as high potential sources to be used in cattle.

<p>This study aimed to evaluate the viability of replacing corn meal with citrus pulp (0, 25, 50, 75, and 100 % dry matter of corn meal) by evaluating several nutritional parameters such as intake and digestibility of nutrients, and ruminal fermentation parameters. The diets were formulated to be isoproteic with a roughage:concentrate ratio of 60:40. Five crossbred lambs with an initial average weight of 26.1 ± 1.8 kg were used and distributed in a 5 x 5 Latin Square design. For digestibility of nutrients was carried out to feed, orts, and feces collection. The evaluated nutrients were dry matter, crude protein, ether extract, ash, neutral detergent fiber, fiber acid detergent and lignin. Were determined nitrogen and carbohydrate fractions, and ruminal fermentation parameters (N-NH 3 and ruminal pH). The results were subjected to analysis of variance and regression analysis (t-test; ? = 0.05). Citrus pulp inclusion in the diets did not affect intake and digestibility of nutrients, or the pH and the NH3-N content of the rumen fluid. Citrus pulp can be used as a total substitute for corn in concentrate or up to 26.5% in the total ration for lambs (dry basis). </p>
