This study evaluated food intake and productive performance of crossbred (½ Santa Inês x ½ dorper) lambs supplemented with different levels of faveleira (Cnidoscolus quercifolius Pohl) fodder salt. Thirty male sheep fed tifton grass hay, water, and faveleira fodder salt were randomly allocated into five treatments with six replicates each. The treatments consisted of diets with different inclusion levels of faveleira hay in the fodder salt composition: Treatment 1 (1% mineral salt + 99% faveleira hay), Treatment 2 (3% mineral salt + 97% faveleira hay), Treatment 3 (5% mineral salt + 95% faveleira hay), Treatment 4 (7% mineral salt + 93% faveleira hay), and Treatment 5 (Control - 100% mineral salt). Intake of dry matter, tifton hay and water, average daily gain, feed conversion, and feed efficiency were not affected by fodder salt supplementation (P > 0.05). There was a significant difference (P < 0.05) in fodder salt intake between Treatments 4 and 5, and daily intake was higher in animals submitted to Treatment 4 (61.0 g day-1). Mineral salt intake increased significantly with increasing mineral salt levels in the diet. However, no significant difference was observed in average daily gain across treatments, indicating that faveleira hay, even in small quantities, and tifton hay were able to meet the nutritional requirements of animals to support a good average daily gain. The inclusion of up to 99% faveleira hay in fodder salt formulations did not affect voluntary intake of forage, water and dry matter, average daily gain, feed conversion, and feed efficiency. Lambs supplemented with faveleira fodder salt had average daily gains within the optimal range for slaughter and high feed conversion and feed efficiency values. Faveleira was shown to be an effective supplementary feed alternative in sheep.

Abstract Fermented liquid feeding has proved beneficial for weaner pigs; however, there is limited research on its effect on the growth and feed conversion efficiency (FCE) of grow-finisher pigs. Microbial decarboxylation of amino acids is associated with whole diet fermentation, while wet/dry and liquid feeding reportedly improve growth compared with dry feeding. The objective of this study was to determine the effect of wet/dry feeding and fresh, fermented whole diet, and fermented cereal liquid feeding on pig growth, feed efficiency, and carcass quality in grow-finisher pigs. Pigs were allocated to one of four dietary treatments in two experiments: 1) Single-space wet/dry feeders (WET/DRY), 2) Fresh liquid feeding (FRESH), 3) Fermented cereal liquid feeding where the cereal fraction (38% barley, 40% wheat) of the diet was fermented prior to feeding (FERM-CER), and 4) Fermented whole diet liquid feeding where the whole diet was fermented prior to feeding (FERM-WH). In exp. 1, pigs were fed the experimental diets for 68 d prior to slaughter (29.8 kg ± 0.92 SE to 102.3 kg ± 0.76 SE). Overall, average daily gain (ADG) was 1,094, 1,088, 1,110, and 955 g/d (SE = 13.0; P &lt; 0.001) and FCE was 2.26, 2.37, 2.40, and 2.88 (SE = 0.031; P &lt; 0.001) for treatments one through four, respectively. Pigs fed FERM-WH were lighter at slaughter than pigs fed the other three treatments (P &lt; 0.001). In exp. 2, pigs were on treatment for 26 d prior to slaughter (85.3 kg ± 1.69 SE to 117.5 kg ± 0.72 SE). Overall, ADG in exp. 2 was 1,103, 1,217, 1,284, and 1,140 g/d (SE = 27.9; P &lt; 0.01) and FCE was 2.78, 2.99, 2.95, and 3.09 g/g (SE = 0.071; P = 0.05), for treatments one through four, respectively. There were no significant differences observed between treatments for apparent total tract digestibility of dry matter, organic matter, nitrogen, gross energy, or ash. Higher lactic acid bacteria counts and lower Enterobacteriaceae counts and pH were observed in FERM-CER and FERM-WH compared with WET/DRY and FRESH. Ethanol concentrations were almost 4-fold higher in FERM-CER troughs than FRESH troughs and 5-fold higher in FERM-WH than FRESH troughs. To conclude, FERM-WH resulted in poorer growth and FCE compared with WET/DRY, FRESH, and FERM-CER, probably due to amino acid degradation and a loss in gross energy found in FERM-WH.

Abstract Ambitine Feed Additive (AMB), a proprietary blend of phytogenics and acidifiers (PMI, Arden Hills, MN), is formulated to help mitigate late finishing stress in pigs. Several studies using AMB in the late finishing period resulted in improved pig performance. A meta-analytic method used 13 studies (3 studies with ractopamine and 10 studies without) to determine the overall impact of AMB on average daily gain, average daily feed intake, and feed conversion. The combined data were considered a randomized complete block design. Analysis of variance was completed using the GLIMMIX procedure of SAS (9.4; Cary, NC) and least squares means were compared using Fisher’s least significant difference (P &lt; 0.05). In the analysis of 10 studies with no added ractopamine (73 pens/treatment of 5 to 10 pigs/pen and 48 pens/treatment of 17 to 20 pigs/pen), pigs provided AMB had higher average daily gain (0.90 vs 0.86 kg/d; P &lt; 0.05), increased average daily feed intake (2.99 vs 2.94 kg/d; P &lt; 0.05), and improved feed efficiency (0.30 vs 0.29 kg gain/kg feed intake; P &lt; 0.05) compared to pigs fed control diets. Additionally, when pigs were provided AMB in addition to ractopamine (3 studies; 33 pens/treatment of 18 to 22 pigs/pen), average daily gain was increased 4.7% (1.206 vs 1.152 kg/d; P &lt; 0.05) and feed efficiency was improved 5.3% (0.40 vs 0.38 kg gain/kg feed intake; P &lt; 0.05) compared to pigs provided only ractopamine, with no difference in feed intake. Pigs provided AMB in addition to ractopamine had increased hot carcass weight and dressing percentage (P &lt; 0.05) compared to those provided ractopamine alone. In conclusion, providing AMB to pigs in late finishing improved ADG and feed efficiency and the improvement was maintained when ractopamine was included in the diets.

Abstract: The objective of this work was to evaluate the performance of young Nellore bulls and of young dual-purpose dairy bulls fed proportions of 'Mulato II' grass silage (400 and 100 g kg-1), in diets with high levels of concentrate, as well as to evaluate the cost of this feed. Sixteen young Nellore bulls and 16 young dairy crossbred bulls were used, with initial average weight of 380.69±10.45 and 376.94±17.16 kg, respectively, and average initial age of 24 months. A completely randomized experimental design was carried out in a 2x2 factorial arrangement. The highest silage proportion caused a 13% increase in dry matter intake (percentage of body weight) and a 19.7% decrease in dry matter digestibility of the diet, but it did not alter the intake of total digestible nutrients, nor the average daily gain or carcass characteristics. Nutrient intake and digestibility, average daily gain, and carcass characteristics (except conformation) did not change due to the genetic group of animals. Feed conversion was 18.3% better in young dairy bulls. In diets with high levels of concentrate, the proportion of 400 g kg-1 of 'Mulato II' grass silage, in comparison with that of 100 g kg-1, does not affect the productive performance, nor the main carcass characteristics of economic interest of confined young bulls, but reduces feeding costs.

Thirty-five Yankasa rams initially weighing 22.5kg on the average were individually fed one of five diets formulated to differ in the roughage to concentrate ratio: 70:30, 60:40, 50:50, 40:60, 30:70. The diets were isonitrogenous and isocaloric. Average daily gain (ADG) and feed efficiency show­ed a linear response to increasing levels of dietary concentrate. Feed intake on the other hand did not reveal any significant difference. Both dry matter and nitrogen digestibility tended to increase with in­creasing dietary concentrate. Dressing percentage, kidney and mesenteric fats also increased with in­creasing concentrate level. Given the overall perfor­mance and current prices of feedstuffs, rams and mutton, it would seem that 50 to 60% dietary con­centrate is optimal for fattening.

Abstract The aim of this trial was to evaluate the effect of encapsulated calcium ammonium nitrate as a partial substitute for soybean meals in the concentrate dry matter intake, average daily gain and feed efficiency of Nellore young bulls under grazing conditions, during the dry season. Sixty-four weaned Nellore (initial BW = 177.46±3.77 kg and 9 mo old) were used in a completely randomized assay. The study lasted 84 days on the dry season. Animals were allotted into 16 paddocks of 1.0 ha each of Urochloa brizantha, randomly assigned into one of two treatments: (CTL) supplement with 25% CP, without nitrate inclusion and; (ENP): supplement with 25% CP, with a inclusion of 50 g of encapsulated calcium ammonium nitrate to each 100 kg of body weight. Animals were fed with concentrate at 1.0% of body weight. Concentrate offered was monitored daily as well as his refusals were collected and weighed to determine daily concentrate dry matter intake (DMI) and feed efficiency (F:G). Animals were weighed every 28 d for calculating average daily gain (ADG). Data were analyzed as a completely randomized design, using ANOVA (α = 0.05). No effects of treatments (P &gt; 0.3487) were observed for final BW (246.69 kg). The same for concentrate dry matter intake (P &gt; 0.0550). Animals consumed 2.34 kg of supplement per day. The average daily gain (0.832 kg, P &gt; 0.2649) and feed efficiency (0.356 kg, P &gt; 0.7315) were not affected by the inclusion of nitrate. The inclusion of encapsulated calcium ammonium nitrate in supplement to Nellore young bulls under grazing conditions during the growing phase did not affect the performance.

Three factorial experiments were conducted to determine the relative feeding value of dry barley (DB) and high-moisture barley (HMB), and to evaluate the influence of method of ensiling (Pit vs. Harvestore® (HAV) silo), source of roughage (hay vs. silage), and level of concentrate (90 vs. 75%) on the performance and carcass characteristics of feedlot cattle. In exp. 1, 252 steers (initial wt 357 kg) were assigned on the basis of weight to six treatments (two pens × 21 animals per pen). A mixed diet consisting of 85.2% barley grain (dry matter (DM) basis) was offered free choice. The barley portion of the ration consisted of either 0, 25, 50, 75 or 100% DB with the balance being HMB from a pit silo. The sixth treatment consisted of feeding 100% HMB for the first 57 d and 100% DB for the remainder of the trial. Overall average daily gain (ADG) for steers fed 100% DB (1.70 kg d−1) was significantly higher than observed for animals fed 100, 75 or 50% HMB (1.46, 1.49 and 1.56 kg d−1, respectively). The kg of feed DM required per kg gain (FC) varied between 5.76 and 7.13 and was not (P > 0.05) influenced by treatment. No differences (P > 0.05) were observed in carcass characteristics. In exp. 2, 360 steers (initial wt 340 kg) were allotted on the basis of weight to six treatments designed to evaluate the effect of source (Pit vs. HAV) and level of HMB, in diets containing 10.2% silage, on animal performance. Overall ADG (1.11 – 1.17 kg d−1), FC (6.66 – 7.01) and carcass characteristics were similar (P > 0.05) for animals fed Pit HMB, HAV HMB and DB. In exp. 3, 264 weanling calves (initial wt 216 kg) were allotted on the basis of weight to six treatments which differed in type of barley (HMB vs. DB), source of roughage (hay vs. silage) and level of concentrate (75 vs. 90%; DM basis). The feeding period was 127 d. Daily gains varied between 0.78 and 0.91 kg d−1 and FC ranged from 6.40 to 7.10 and were not influenced (P > 0.05) by source of barley or source or level of roughage. While animals fed DB had significantly higher ADG than those fed HMB in exp. 1, the overall results from the three experiments indicate that on a DM basis HMB has similar feeding value to DB, and that there is no major difference between Pit and HAV-stored HMB for feedlot cattle.

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.

An experiment was conducted to obtain progeny test comparisons of Finnish and Canadian Ayrshire bulls for veal and beef production. A total of 83 male calves from four Canadian and four Finnish sires was tested. Best linear unbiased estimates of differences between veal calf progeny of Finnish and Canadian bulls for time on test, average daily gain and feed conversion were 4.00 ± 5.63 days, −.044 ±.038 kg/day and.062 ±.067 kg dry matter intake/kg gain, respectively. For veal carcass traits, progeny differences between Finnish and Canadian bulls for dressing percent and carcass grade, quality, finish and color scores (scores ranged from 1 to 3, except for color score which ranged from 1 to 2, with high score desirable) were.25 ± 1.13%, −.085 ±.232,.146 ±.303,.122 ±.302 and.104 ±.192, respectively. When raised for beef, differences between Finnish and Canadian sired steers were.015 ±.019 kg/day for feedlot average daily gain and.21 ±.66% for dressing percent. None of these differences were significant (P >.05). Based on these results, the importation of Finnish semen would not be expected to materially change the veal and beef performance of Ayrshires in Canada.

Abstract OutPace® Feed Additive (OP), contains a carefully researched blend of activated medium chain fatty acids (MCFAs; PMI, Arden Hills, MN), formulated to help mitigate the effects of stress in nursery pigs. Several studies using OP in both late and full nursery periods resulted in improved pig performance. A meta-analysis using 9 studies (4 studies during late nursery [15 to 26.8 kg BW] and 5 studies during the full nursery [5.9 to 25.4 kg]) was done to determine the impact of OP (included at 0.25% Phase 1 and 2; 0.125% Phase 3) on average daily gain, average daily feed intake, and feed conversion. The combined data was considered a randomized complete block design. Analysis of variance was completed with mixed models using the GLIMMIX procedure of SAS (SAS 9.4, SAS Institute Inc., Cary, NC) and least squares means were compared using Fisher’s least significant difference (P &lt; 0.05). In the analysis of 5 studies conducted in late nursery (45 pens/treatment of 6 to 20 pigs/pen), pigs provided OP had higher average daily gain (0.67 vs 0.63 kg/d; P &lt; 0.05), increased average daily feed intake (0.99 vs 0.97 kg/d; P &lt; 0.05), and improved feed efficiency (0.67 vs 0.65 kg gain/kg feed intake; P &lt; 0.05) compared to pigs fed control diets. Additionally, when pigs were provided OP throughout the nursery period (20 pens/treatment of 7 to 20 pigs/pen), average daily gain was increased 6.1% (0.48 vs 0.45 kg/d; P &lt; 0.05), average daily feed intake tended to be increased 2.2% (0.62 vs 0.61 kg/d; P &lt; 0.1), and feed efficiency was improved 2.7% (0.76 vs 0.74 kg gain/kg feed intake; P &lt; 0.05) compared to pigs provided control diets. In conclusion, providing OP to pigs during the nursery period improved ADG and feed efficiency.
