The objective of this work was to evaluate intake, nutrient apparent digestibility and ingestive behavior of sheep fed rations with cashew nut meal (CNM) at the levels of 0; 10; 20 and 30% in the concentrate ration. It was used a double 4 × 4 Latin square experimental design. Intakes of dry matter (DM), organic matter, crude protein, mineral matter, non-fibrous carbohydrates and total digestible nutrients were not influenced by the addition of CNM, however, intake of neutral detergent fiber (NDF), acid detergent fiber and total carbohydrates presented a quadratic behavior with the increase of content of lipids in the ration. Apparent digestibility of DM, organic matter, crude protein, NDF, acid detergent fiber and non-fibrous carbohydrates was not influenced by the addition of CNM in the rations; however digestibility of ether extract and total carbohydrates presented quadratic and linear behavior, respectively. It was not observed any significant differences in time spent with feeding and rumination, however, total chewing time was influenced, presenting increasing linear behavior with the levels of CNM. Concerning to intakes of dry matter and NDF per hour, feed efficiency and rumination were not affected by increase on lipid content in the rations. Ruminating chews time per rumen bolus, number of ruminated boli and the number of ruminating chews per day were not influenced by experimental rations. In sheep feeding management, it is suggested as a feeding alternative the use of up to 30% of CNM in the concentrate ration if it is available.

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.

ABSTRACT The aim of this study was to investigate the effect of odontoplasty on apparent digestibility of diet for horses, consumption time, and particle size of feces. Nine horses were used, aged 14.5±3.3 years and weightng 531±38.7kg. The diet consisted of 1.5% of live weight (LW) in Tifton 85 hay and 0.75% of LW in concentrate for both assays. The experiment consisted of two tests of apparent digestibility using the method of total collection, before and after the odontoplasty, where the consumption time of hay and concentrate was also evaluated and the particle size of the feces was analyzed. An effect (P<0.05) of odontoplasty on the apparent digestibility coefficients of dry matter, organic matter, crude protein, neutral detergent fiber and acid detergent fiber was observed. Effect of the consumption time for the concentrate (P<0.05) was observed, but not for the forage (P<0.05). There was more retention (P<0.05) of the fecal particles in the sieves of bigger granulometry. The odontoplasty increases the digestibility of dietary nutrients and feces particle size, without changing feces quality. Animals after the procedure have shorter concentrate consumption time.

The objective of the present study was to evaluate the inclusion of 0%, 10%, 20%, and 30% of scrapes residual dehydrated cassava (SRDC) in sheep feed on the intake and total digestibility coefficient (DC) of nutrients. We used four sheep with body weight (BW) of 26.0 kg, distributed in a Latin square design. The sheep were placed in metabolism cages and received two meals a day. The variables studied were subjected to analysis of variance and differences were tested using regression analysis at the 5% significance level. We determined that the inclusion of different concentrations of SRDC in sheep feeding did not modify (p &gt; 0.05) the intake of intake of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), or total carbohydrates (TC) expressed in g animal-1 day-1, g kg0.75-1 and %BW). On average 2.83%, 2.58%, 0.34%, 0.07%, 1.62%, 0.91%, and 2.24% of the BW were obtained for intake of DM, OM, CP, EE, NDF, ADF, and TC, respectively. However, the four experimental diets negatively affected the NFC intake and %BW (p &lt; 0.05). Different concentrations (0%, 10%, 20%, and 30%) of SRDC in sheep diets did not influence (p &gt; 0.05) the digestibility coefficient of most of the variables measured (DM, OM CP, EE, NDF, ADF, TCH, NFC, with average values of 67.79%, 67.61%, 53.87%, 81.42%, 55.61%, 39.07%, 70.95%, and 91.48%, respectively. Thus, we conclude that the inclusion of up to 30% of SRDC in sheep diets would not affect intake or nutrient digestibility

This study aimed to evaluate the quality of leucaena, gliricidia, and pornunça silages with different levels of old man saltbush inclusion in their composition. A completely randomized design was used with five levels of old man saltbush (Atriplex nummularia) inclusion (0, 25, 50, 75, and 100%) in leucaena (Leucaena leucocephala), gliricidia (Gliricidia sepium), and pornunça (Manihot sp.) silages, with 5 replications per treatment, totaling 75 experimental mini-silos maintained in a covered shed and free of opportunistic animals. Silos were opened after 100 days of ensilage, and the silage of the first 15 cm of their ends was discarded. The remaining material was homogenized and sampled for determining the bromatological composition, in vitro digestibility, and fermentation profile. Old man saltbush inclusion levels in leucaena silages promoted a negative linear effect for dry matter, organic matter, crude protein, ethereal extract, pH, and ammoniacal nitrogen, while a positive linear effect was found for mineral matter, in vitro dry matter digestibility, total carbohydrates, non-fibrous carbohydrates, and propionic acid (P < 0.05). This silage also had a quadratic effect for lactic acid. Gliricidia silages showed a positive linear behavior for dry matter, mineral matter, and total carbohydrates, whereas organic matter, crude protein, and ethereal extract presented a negative linear behavior (P < 0.05). The contents of organic lactic, acetic, and propionic acids showed a quadratic effect for gliricidia silage as old man saltbush levels increased (P < 0.05). Regarding pornunça silage, dry matter, mineral matter, total carbohydrates, propionic acid, and butyric acid presented a linear increasing behavior, while organic matter, crude protein, ethereal extract, and non-fibrous carbohydrates presented a linear decreasing behavior (P < 0.05). Lactic acid and acetic acid concentrations for pornunça silage showed a quadratic behavior according to the increasing old man saltbush inclusion levels (P < 0.05). The highest contribution of old man saltbush in the silages promoted changes in the profile of organic acids, allowing an improvement in silage quality, favoring lactic fermentation rather than acetic fermentation. Butyric acid contents were low for all treatments and indicated the control of undesirable fermentation processes. These results indicate that old man saltbush inclusion in silage composition may contribute to bromatological composition and fermentation process of the studied silages.

Lupins are suitable candidates to replace soybean meal in livestock feeding in the Mediterranean area, presenting a solution for the European Union’s dependence on soybean importations. This study aimed to assess the effect of incorporating Lupinus albus and Lupinus luteus into Churra da Terra Quente lambs’ diets on growth performance and digestibility. Two trials were conducted over two years. In trial 1, two experimental diets containing 50 g/kg Lupinus albus and 50 g/kg Lupinus luteus were tested. In trial 2, lambs were fed with diets containing higher incorporations of Lupinus luteus (100, 150, and 200 g/kg: LL10, LL15, and LL20, respectively). Total dry matter, hay dry matter, and crude protein intake were calculated, as well as average daily gains. At the end of the growth trials, dry matter, organic matter, and NDF digestibility was determined. Incorporating 50 g/kg of lupins did not affect (p > 0.05) the performance. Lambs fed on LL20 diets presented the lowest HDMI and CPI values (p < 0.05). The highest intakes (p < 0.05) were observed from LL15 lambs. No differences were found in apparent digestibility coefficients between diets (p > 0.05), except for NDF digestibility which was highest (p < 0.05) for LL20. The optimum level of lupin inclusion in lambs’ diets seems to be 150 g/kg.

SUMMARY It was evaluated the effect of feed supplementation at 0.4; 0.8 and 1.2% of body weight (BW) on intake and digestibility of crossbred goats finished on caatinga, in relation to crossbred goats not supplemented (0.0% of BW). Thirty-two crossbred, Anglo-Nubian goats were used, eight months old and with body weight of 18 ± 2.5 kg, organised into randomised blocks, which were kept on 37 hectares of caatinga from 7 h to 16 h. Intake of dry matter, organic matter, crude protein, ether extract, neutral and acid detergent fibre, total carbohydrates and total digestible nutrients was influenced (P<0.05) by the levels of feed supplementation, with linear increases of 202.31; 179.42; 25.05; 11.83; 35.79; 12.27; 142.63 and 166.79 g animal-1 day-1 respectively. There was a substitution effect (P<0.05) on dry matter intake when using feed supplementation at 0.7% BW. Feed supplementation resulted in positive linear effect (P<0.05) for digestibility of dry matter, organic matter, crude protein, ether extract, total carbohydrates, total digestible-nutrient content and digestible energy, with an increase of 17.15; 16.64; 19.07; 44.74; 15.15 and 17.56% for dry matter, and 0.69 Mcal kg-1 of dry matter respectively. Final body weight, total gain and average daily gain, showed a linear increase (P<.005) of 2.60, 3.09 and 0.036 kg per percentage point of each additional level of supplement. Feed supplementation increases the intake and digestibility of total dry matter and nutrients, a fact that makes greater performance possible, and recommends use up to a level of 0.7% BW to avoid any substitution effect.

1. Grass from the same sward was ensiled without additive, with 14.6 g formic acid/100 g crude protein or 10.8 g formic acid and 10.6 g formaldehyde/100 g crude protein. Similar grass was dried and pelleted. Drying or ensiling with the mixture reduced solubility of N in the preserved grass but formic acid increased it, and ensiling without additive increased it even more. Apparent digestibility of N in the rumen of cows tended to decrease with decrease in solubility. Digestibility in vitro of the mixed diet given to the cows, calculated from digestibility of the separate components, agreed well with the values in vivo for diets with silages, but was high for that with dried grass.

SUMMARYThe nutritional value of dried poultry excreta was investigated by determining the apparent digestibility of dry matter, organic matter, nitrogen, energy and copper in five diets containing 0 to 100% of this feed. Dried poultry excreta supplied 20·21% apparently digestible crude protein and approximately 1·57 or 1·74 Mcal of metabolizable energy per kg dry matter.The copper in dried poultry excreta was found to be less digestible than the copper in barley. It is concluded that, as far as copper levels are concerned, dried poultry excreta are safe for ruminants, and are a source ofcheap protein. More detailed work is needed to determine the metabolizable energy of the material accurately.

Aim The aim of this study was to investigate the effects of two growth-promoting implants (zeranol and oestradiol-17β) on performance and feed digestibility of finishing White Fulani cattle in the feedlot. This was with a view to determining an alternative means of enhancing cattle performance without grazing the animals. Methods A 60-day feedlot trial was conducted using 27 stocker White Fulani bulls that were allotted randomly to three treatment groups (i.e. non-implanted, oestradiol-implanted and zeranol-implanted) in a completely randomised experimental design. Cattle were offered a compounded feedlot ration consisting of 14% crude protein ad libitum. The bulls were weighed initially and fortnightly thereafter for the duration of the study. Coefficients of dry matter and nutrients digestibility were determined using lignin as an internal marker. Data were analysed using the general linear model procedure of ANOVA and mean values were compared using Fisher’s least significant difference (l.s.d.0.05). Key results The average final liveweight, total weight gain, average daily gain (ADG) and average daily feed intake (ADFI) of implanted feedlot cattle were higher (P &lt; 0.05) than for non-implanted cattle; and higher in oestradiol-implanted cattle compared with zeranol-implanted ones. The ADG was 29.16 and 20.48% higher, and the ADFI was 35.06 and 18.18% higher for oestradiol-implanted and zeranol-implanted feedlot cattle, respectively than for non-implanted cattle. Irrespective of the treatment, feed conversion ratio of experimental bulls remained below the range (4.5–7.5) established for feedlot beef cattle; an indication of better efficiency of feed utilisation by White Fulani cattle. The apparent digestibility of dry matter (59.76–64.31%) of the feedlot ration was in the order: non-implanted = oestradiol-implanted &gt; zeranol-implanted while the apparent digestibility of crude protein (73.91–77.99%) was in the order: non-implanted &gt; oestradiol-implanted = zeranol-implanted. Conclusions and implications The results of this study show that the use of an oestradiol implant in finishing zero-grazed White Fulani cattle was beneficial for improving growth performance. Both implanted and non-implanted cattle showed good coefficients of nutrient digestibility, indicating that the mode of action of the growth implants in enhancing performance characteristics does not depend on indices of digestibility.

Four concentrations (0, 200, 400, 600 and 800 mg extract per ml of water) of mesquite extract were used as phytogenic additive to verify the potential to increase the nutritional value of the feed, ruminal parameters (primarily propionate production) and nitrogen use efficiency, microbial protein synthesis and quantify the reduction of ciliated protozoa and characterize the ingestive behavior of sheep. Ten adult male sheep were subjected to a 5 × 5 double Latin square design. Prior to feeding, the animals received the mesquite extract. Nutrient intake was estimated from the difference of the amount of feed provided and the total surplus. Rumen content samples were collected to evaluate the profile of short-chain fatty acids, ammonia nitrogen, pH, ciliated protozoa, turnover rate and disappearance rate. To estimate the microbial protein synthesis, the technique of purine derivatives was used. The mesquite extract quadratically increased (P < 0.05) the digestibility of dry matter, organic matter, crude protein and total digestible nutrients, as well as increased propionate production, acetate:propionate ratio and microbial protein synthesis. The numbers of ciliate protozoa in the rumen decreased as a result of mesquite extract inclusion in the diet. The use of mesquite pod extract at a concentration of 488 mg/mL is recommended to improve digestibility of dry matter, organic matter, crude protein and total digestible nutrients, and to optimize microbial protein synthesis and increase propionic acid production.
