Lotus Uliginosus

The aim of this study was to evaluate the use of restricted grazing of an improved natural pasture as an alternative to conventional protein supplements for weaned lambs grazing natural pastures during summer–autumn. Two natural pastures that differed in dry matter allowances were used as basal diets. Sixty Corriedale lambs, 3 months old, were divided into 10 homogeneous groups. For each natural pasture, one group of lambs was randomly assigned to one of the following treatments (at 10 lambs/ha): continuous grazing (control); control + protein block (150 g/lamb. day); control + soybean meal (100 g/lamb. day); control + supplemental protein obtained from grazing for 3 h/day a natural pasture improved with Lotus uliginosus cv. Maku; or same as previous, except that grazing was allowed 1 in 3 days. Performance results (final bodyweight, average daily gain, and difference between initial and final body scores) were analysed as a completely randomised block design with subsampling. Lambs grazing 3 h/day or 1 in 3 days on improved pasture or supplemented with soybean meal showed better (P < 0.05) performance than non-supplemented lambs. Lambs consuming the protein block performed similarly (P > 0.05) to control lambs. The experiment demonstrated that feeding strategies using controlled grazing of natural pastures improved with lotus Maku or soybean meal supplementation are effective to achieve target growth rates of weaned lambs grazing natural pastures in summer–autumn.

The Relationship

The aim of the present study was to describe the relationship between increasing levels of soybean meal (SBM) supplementation and the growth rate of weaned lambs grazing brown midrib (BMR) sorghum. Sixty Corriedale weaned lambs (3 months old) were divided into 12 homogeneous groups and allocated into three blocks of BMR sorghum (stocking density: 50 lambs/ha) of four plots each. In each block, lambs were assigned (5 lambs/plot.block) to one of the following treatments: grazing sorghum, grazing sorghum + 115 g SBM/lamb.day, grazing sorghum + 230 g SBM/lamb.day, and grazing sorghum + 345 g SBM/lamb.day. Rotational grazing management was implemented. Lambs were weighed at the beginning of the experiment. Final bodyweight and average daily gain (ADG) were analysed according to a completely randomised block design. The relationship between SBM supplementation level and ADG was tested and a non-linear fit with a prediction model of first-order kinetics was determined. Supplemented lambs had a higher (P < 0.036) final bodyweight and presented higher (P < 0.001) ADG than did non-supplemented lambs (31 kg and 120 g/lamb.day vs 26 kg and 55 g/lamb.day in supplemented and non-supplemented lambs, respectively). An asymptotic ADG value estimated by the model of 143.26 g/lamb.day BMR sorghum appeared to be an adequate summer grazing alternative for weaning lambs. SBM supplementation would improve the performance of animals however the level of supplementation would depend on the productive goal.

Two experiments were conducted to determine the relationship between corn particle size and soybean meal treatment on growth, diet digestibility, and nitrogen balance of growing steers. In the first experiment, 40 medium-frame beef steers (250 ± 11 kg) were fed individually for 140 d a diet based on grass silage offered for ad libitum consumption and supplemented with either 3.5 kg of DM d-1 of cracked corn (CC) or ground corn (GC) and with 450 g of DM d-1 of solvent extracted (SS) or lignosulfonate-treated soybean meal (Soypass™ SP). Dry matter intake was not affected by treatments and averaged 8.6 ± 0.3 kg d-1 (P > 0.10). Average daily gain was higher for animals receiving the ground corn than those fed cracked corn. Feed to gain ratio was not affected by treatments. There was an interaction between treatments for plasma urea-N concentration, with source of soybean meal having no effect with CC. When compared with SS, SP supplement reduced plasma urea-N when fed with GC. No effect of soybean meal and its interaction with corn processing was observed on growth performance. In the second experiment four additional steers were used in a 4 × 4 Latin square design to evaluate diet digestibility and nitrogen balance. There was an interaction between treatments for starch apparent digestibility and N retained, the values being respectively, 90, 86, 93, and 92% (SEM = 1.2; P < 0.01) and 36, 42, 44 and 41 g d-1 (SEM = 2.8; P < 0.03) for CCSS, CCSP, GCSS and GCSP, respectively. Altogether, the results indicate a slight advantage to reduce particle size of corn in growing steers fed grass silage. However, soybean meal treatment resulted in limited effects on growth and digestion. Key words: Rumen carbohydrate, undegradable protein, performance, steers

Abstract: The objective of this work was to evaluate the effect of narasin inclusion in mineral and protein supplements on the performance and supplement intake of grazing beef yearlings. One hundred and fifty Nellore yearlings with 17.0±0.06 months of age and 219.7±1.62 kg initial body weight (BW) were allocated into 30 experimental units (EUs), with five animals each. The EUs were assigned to 16 paddocks, which were continuously stocked for 28 days, followed by 28 days of rest. A randomized complete block design was used. The experiment lasted 140 days, divided into five periods of 28 days each. The assessed treatments were: control mineral supplement (CON); CON + 1,800 (N1800) or 2,750 (N2750) mg narasin per kilogram of supplement; and protein mineral supplement (PROT) or PROT + 360 mg narasin per kilogram of supplement (PROT 360). The inclusion of narasin in the mineral supplement increased average daily gain (ADG) in the first period and decreased supplement intake in the first, second, and third periods, when compared with the CON treatment. The ADG and supplement intake were similar between the N1800 and N2750 treatments. Narasin has a positive effect on ADG up to 28 days of supplementation and controls mineral supplement intake, without compromising this gain.

Twenty barrow and twenty gilt Berkshire x Large White pigs were fed barley based diets containing protein supplements of either 13 per cent soybean meal, 9 per cent fishmeal, 14.5 per cent safflower meal plus 0.2 per cent I-lysine mono hydrochloride plus 0.1 per cent methionine or 14.5 per cent safflower meal plus 4.5 per cent fishmeal from 46.4 to 87.0 kg liveweight. All diets were fed individually at a restricted feeding scale. The safflower meal diets were also fed ad libitum. Barrows and gilts fed ad libitum recorded a 65 and 27 per cent improvement respectively in average daily gain and had slightly fatter carcases than those fed comparable diets restrictively. Feed conversion ratio was not significantly affected by level of feeding. Growth and carcase attributes of pigs fed diets restrictively were similar apart from the feed conversion ratio of pigs fed the amino acid supplemented safflower meal diet, which was inferior (P < 0.05) to those fed the soybean meal supplemented diets. Barrows grew faster and produced fatter carcases than gilts, A significant sex x diet interaction occurred from which it was concluded that gilts, but not barrows, could be fed ad libitum without detriment to the quality of the carcase.

Growth Experiments

An experiment was undertaken to determine the effect of lignosulfonate (LSO3) treatment on the rumen-undegradable protein (RUDP) value of canola meal (CM) and soybean meal (SM). Canola meal and SM were treated with 7% LSO3 and heated (95 °C) for 1 h. Treated and untreated meals were compared in vitro, in situ and in digestibility and growth experiments using Romanov × Suffolk and Romanov × Dorset lambs. Lambs were fed four barley-based diets [13.5% crude protein (CP)] with one of CM, SM, LSO3-treated CM (LSO3-CM) or LSO3-treated SM (LSO3-SM) as protein supplements. Lignosulfonate treatment increased acid detergent insoluble nitrogen (ADIN) five-fold in SM and threefold in CM. After 6 h incubation with ruminal fluid, ammonia production from LSO3-treated meals was one-half that from untreated meals. Lignosulfonate treatment reduced (P < 0.01) in situ rates of dry matter (DM) and protein disappearance and the soluble DM and protein fractions for both SM and CM, but not the potentially digestible fractions. No differences in feed conversion or average daily gain (P > 0.05) were found among the treatments. Although LSO3 treatment did not improve the ADG of lambs fed barley-based diets, it increased the RUDP value of SM and CM without adverse effects on digestibility.

Abstract Four experiments were conducted to determine the effects of increasing soybean meal (SBM) level in diets with or without 25% distillers dried grains with solubles (DDGS) on growth performance of nursery pigs raised in university or commercial facilities. Treatments were arranged in a 2 × 3 factorial with main effects of SBM (27.5%, 32.5%, or 37.5% of the diet) and DDGS (0% or 25% of the diet). A total of 296, 2,502, 4,118, and 711 pigs with initial body weight (BW) of 10.6, 11.7, 12.5, and 12.3 kg were used in Exp. 1, 2, 3, and 4, respectively. There were 10, 16, 13, and 12 replicates per treatment in Exp. 1, 2, 3, and 4, respectively. After weaning, pigs were fed common diets for approximately 21 d. Then, pens of pigs were assigned to treatments in a randomized complete block design with BW as the blocking factor and experimental diets were fed for 21 d. Pigs were weighed and feed disappearance measured to calculate average daily gain (ADG), average daily feed intake (ADFI), gain-to-feed ratio (G:F), and caloric efficiency (CE). Data were analyzed using the GLIMMIX procedure of SAS with block as a random effect and treatment as a fixed effect. Single degree-of-freedom contrasts were constructed to test the linear and quadratic effects of increasing SBM and their interactions with DDGS. Pigs used in all experiments did not undergo major health challenges during the experimental period and due to the low number of mortality and cull events, statistical analysis was not performed on these variables. The average cull rate was 0.7%, 0.5%, 0.2%, and 0%, and the mortality rate was 0.7%, 0.3%, 0.4%, and 0% in Exp. 1–4, respectively. There were interactions (P ≤ 0.039) between SBM and DDGS for G:F and CE in Exp. 2 and for ADG and ADFI in Exp. 3. These were mostly driven by increasing SBM negatively affecting performance in a greater magnitude when diets contained DDGS compared to diets without DDGS. The main effects of DDGS and SBM were more consistently observed across experiments. Pigs fed diets with 25% DDGS had decreased (P ≤ 0.001) ADG and ADFI in all experiments, as well as poorer (P ≤ 0.028) G:F and CE except for Exp. 3. Feeding increasing amounts of SBM generally did not result in any major impact in ADG but consistently improved (linear, P ≤ 0.078) G:F and CE across experiments.

Abstract Consumers are concerned about the safety of livestock feed stuff with the increasing use of genetically modified organisms (GMO).The objective of the present experiment was to compare the effect of non-GMO sugar-beet pulp (SBP) and canola meal (CM) in the diet with GMO corn-soybean meal basal diets on reproduction performance in gestation-lactation sows and the performance of their litters. A total of 16 lactating sows (Landrace × Yorkshire, Parity = 2.4), were randomly allotted to 1 of 2 treatments with 8 sows per treatment starting from the last 4 weeks of gestation to 21 day of lactation. Treatments consisted of GMO diet (CON) and non-GMO diet (NO). Sows were individually fed gestation and lactation diets that were formulated to meet or exceed NRC (2012) recommendations for all nutrients. The amount of feed consumed during the lactation periods was recorded and used to calculate the average daily feed intake (ADFI). Number of piglets born and piglets weaned were also recorded to calculate the survival rate. Individual piglet body weight (BW) and litter weights were assessed on days 0, and 26 to calculate average daily gain (ADG). All data were subjected to the GLM procedures of SAS in a randomized complete block design. The variability in the data was expressed as standard error of means (SEM). A probability level of P&lt; 0.05 was considered to be statistically significant. In the current study, NO treatment diets showed comparable effects on the BW, ADFI, backfat thickness, body condition score, and estrus interval of sows as that of basal diet. In addition, there was also no significant difference in growth performance of piglets fed NO treatment diets compared with CON diet (P &gt; 0.05). In conclusion, the results of the current study indicated the utilization of non-GMO beet pulp, and canola meals do not have any adverse effect on the performance of sows and their litters.

In the first experiment, 39 medium-frame beef steers (456 ± 41 kg) were used in a 2 × 2 factorial arrangement of treatments to evaluate the effect of different feeding strategies to maximize energy and protein deposition on finishing performance and plasma amino acid profile of beef steers fed corn silage ad libitum for 99 d. To achieve this goal, steers were individually supplemented with either 6.6 kg DM d-1 of cracked corn (CC) or ground corn (GC) in combination with 540 g DM d-1 of either solvent extracted (SS) or lignosulfonate-treated soybean meal (Soypass® SP). Dry matter intake, average daily gain and feed to gain ratio were not affected by treatments or by their interaction (P > 0.10). When compared with SS, SP tended to increase (P = 0.07) grade fat (1.3 and 2.2 ± 0.5 mm, respectively). The CC diets reduced the plasma concentration of branched-chained amino acids (P = 0.03) and leucine (P = 0.01), and tended to decrease that of isoleucine (P = 0.06) compared with the GC diets. No effect of diet was observed on plasma urea-N concentration. In the second experiment, four steers were used in a 4 × 4 Latin square design to evaluate digestibility and N balance of the diets used in exp. 1. Reducing particle size of corn increased apparent digestibility of starch (P = 0.01) and tended to reduce apparent digestibility of NDF (P = 0.07). In conclusion, formulating diets with ground or cracked corn in combination with solvent extracted or lignosulfonate-treated soybean meal does not appear to influence steer performance or digestion parameters.

Western-Canadian grown sweet white lupin seed (LS), canola meal (CM) and soybean meal (SM) were compared in situ and in digestibility and feedlot experiments using Romanov × Suffolk lambs. Barley-based (75.5% as fed) diets were isonitrogenous (15.5% crude protein, CP) with LS, CM or SM as protein source. Sunflower hulls were substituted as necessary for protein supplement to ensure the diets were isonitrogenous. The LS used in this trial was relatively low in alkaloids (0.03%), as compared with other lupins, and high in manganese (2347 mg kg−1). In situ, the effective rumen degradability of protein of LS was higher than that of either CM or SM. Rates of DM and protein disappearance were also higher for LS than for CM and SM. Digestibilities of DM organic matter, energy and nitrogen were higher (P < 0.05) in LS than in CM or SM diets, but there were no differences (P > 0.05) among the supplements in digestibilities of starch or NDF. No differences (P > 0.05) were found in feed conversion or DM intake of the three diets. Average daily gain (ADG) of the lambs receiving LS did not differ (P > 0.05) from those of lambs on the other two diets, but lambs on CM had higher ADG (P < 0.05) than lambs on SM. We conclude that LS is comparable to SM and CM as a protein supplement for lambs, provided care is taken to avoid toxic levels of manganese and alkaloids.

A factorial experiment with four dietary levels of supplemental lysine (0.10, 0.15, 0.20, 0.25%), three protein supplements (soybean meal (SBM), canola meal (CM), CM + 50 mg iodinated casein per kg diet), and two sexes of pigs (barrows, gilts) was conducted. Crossbred Lacombe × (Yorkshire × Landrace), specific pathogen-free pigs were randomly allotted at 23 ± 1 kg weight in four replicates to pens of four pigs, individually fed. The pigs were slaughtered at 100 ± 2 kg. The diets were based on barley and wheat (2:1) and were pelleted (4.8 mm diam.). Average daily gain (ADG) responses during the growing period (23–57 kg) to increments of lysine were not significant (P > 0.05) but when ADG was adjusted by regression for variation in feed consumption there was a significant (P < 0.05) linear response (743, 748, 757, 772 g d−1). Feed:gain ratio also showed improvement (P < 0.05): 2.45, 2.44, 2.40, 2.35. Responses to lysine were similar for SBM and CM diets but pigs fed SBM had greater (P < 0.05) ADG than those fed CM (779 vs. 745 g). There was no response to added lysine in the 57–100 kg weight range but pigs fed SBM had greater adjusted ADG than those fed CM (908 vs. 873 g) and better feed:gain ratio (3.33 vs. 3.46). Thyroid status was not affected but iodinated casein improved grower period feed:gain ratio. Carcass quality index was not affected (P > 0.05) by lysine level, protein source, iodinated casein or sex of pig. Pigs fed CM had lower serum zinc than those fed SBM. It was estimated that the addition of 0.25% lysine to diets containing 0.8% lysine resulted in 7% improvement in ADG and efficiency of feed utilization.
