Canola meal (CM) is a locally produced protein source that may be less expensive than soybean meal (SBM). This study evaluated the effects of replacing 0%, 25%, 50%, 75%, and 100% SBM with CM in diets for slaughter ostriches. The CM was added at the expense of SBM and other concentrates, with minor changes in other ingredients. Birds (n = 15 per treatment) were reared from 77 to 337 days old on the trial diets, which were supplied ad libitum for starter, grower, and finisher phases. Bodyweights and feed intake were measured during these phases. No differences (P >0.05) were found between treatments for live weight at the end of each phase, dry matter intake (DMI), average daily gain (ADG) and feed conversion ratio (FCR) over all the growth phases. Although no differences were observed in live weight at the end of each phase, the birds reared on the diet with 50% CM were heaviest at slaughter, and birds reared with 100% CM were lightest (P <0.05). Differences (P <0.05) between diets were observed for the weight at slaughter, weights of the liver and thyroid glands and the pH of the cold carcass. However, no differences (P >0.05) were observed between diets for fat pad weight, dressing percentage, and weights of thighs and Muscularis gastrocnemius. The results indicate that CM could replace SBM in the diets of slaughter ostriches without affecting production traits and slaughter yields.Keywords: alternative protein, average daily gain, canola, dry matter intake, feed conversion ratio, growth, ostrich nutrition, production

The evaluation of the Aceh cattle bulls weight which compensated between forage and concentrate at Superior Livestock Place in IndrapuriABSTRACT. This research was conducted at Superior Livestock Place in Indrapuri District, Aceh Besar  which lasted for 42 days. It was started on November 28th 2012 until January 9th 2013. This research was aims to know about the average daily gain for Aceh cattle bulls which compensated between forage and concentrate by using 12 bulls aged 2-2,5 years old. The design was used a Randomized Design Groups with 4 feed treatments and 3 repetitions. The feed percentages between forage and concentrate are ration A (100% forages), B (80%)forages and 20% concentrates), C (60% forages and 40% concentrates), and D (40% forages and 60% concentrates). The research analysis data were obtained by using ANOVA (Analysis of Variance). The parameters which observed in this study was the average daily gain, consumption, conversion, and efficiency rations. The result showed that the ration dry matter intake highly significantly (P0,01) between treatment A (4,45 Kg), and B (3,61 Kg), C (2,72 Kg), and D (3,38 Kg), but the treatment B and D highly significantly than treatment C (P0,01), the best ration consumption were derived from treatment C. The body weight Kg/bull/day significantly (P0,05) between treatment A (0,47 Kg) and B (0,65 Kg), C (0,60 Kg), and D (0,61 Kg), the best average daily gain were derived from treatment B. The conversion ration showed that highly significantly (P0,01) between treatment A (9,55 Kg), and B (5,55 Kg), C (4,60 Kg), and D (5,59 Kg), the best ration conversion were derived treatment C. Similarly, the efficiency ration showed that highly significantly (P0,01) between treatment A (0,11%), and B (0,18%), C (0,22%), and D (0,18%), C is the best ration efficiency on the treatment.

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.

The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p < 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p < 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.

Abstract The objective of this study was to evaluate the growth performance and apparent total tract nutrient digestibility of Holstein heifers limit-fed diets containing different amounts of wet brewer’s grains (WBG). A 12-wk randomized complete block study was conducted using 30 yearling Holstein heifers [378 ± 27 d of age, and body weight (BW) of 357.8 ± 27.6 kg (mean ± SD)]. Treatments were 0%, 10% and 20% of WBG on a dry matter (DM) basis and diets were formulated to be limit-fed for dry matter intake (DMI) at 2.35% of BW and provided 15% crude protein (CP) and 2.27 Mcal metabolizable energy/kg of DM. Dry matter intake was recorded daily, while BW and skeletal measurements were measured every 2 wk. During week 12, fecal samples were collected directly from the rectum over four consecutive days and composited by heifer to determine apparent total tract nutrient digestibility using acid detergent insoluble ash as a marker. Data were analyzed using the MIXED procedure of SAS. Dry matter intakes, BW, and average daily gain were not different among treatments (P = 0.2, P = 0.4, and P = 0.6, respectively). Dry matter intakes ranged from 8.6 to 9.0 kg/d. Average BW were 404.4, 411.5, and 409.3 kg for heifers fed the 0%, 10%, and 20% WBG diets, respectively. Average daily gains were 1.03, 1.04, and 0.96 kg/d for heifers fed the 0%, 10%, and 20% WBG diets respectively. Skeletal measurements and body condition scores (BCS) were not different among treatments except for the change in heart girth (P &lt; 0.01) and initial BCS (P &lt; 0.01). Apparent total tract digestibilities of DM, organic matter, CP, fat, and hemicellulose were greater or tended to be greater in heifers fed 0% and 20% WBG treatments than heifers fed 10 % WBG (P = 0.04, P = 0.04, P = 0.06, P = 0.06, and P = 0.01, respectively). Neutral detergent fiber, acid detergent fiber, and fat digestibilities were similar among treatments (P = 0.2, P = 0.3, and P = 0.3, respectively). During the digestibility phase, DMI tended to be greater (P = 0.08) for the 10% WBG treatment. These results demonstrate that limit-feeding heifers with diets containing up to 20% WBG could replace soybean- and corn-based concentrates in diets without adverse consequences to the heifer growth performance.

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.

Nineteen calves were reared in individual pens (IP), and twenty calves were grouped in four pens of five calves each (GP) to study the effects of grouping on behaviour and performance. All calves were on an enhanced-growth feeding programme and had unlimited access to starter. Total dry matter intake (DMI) body weight (BW), serum urea, non-esterified fatty acid (NEFA), cortisol, insulin, and glucose concentrations, and immune response to vaccination were measured. Behaviour patterns categorized as: non-nutritive oral behaviour, cross-sucking, inter-sucking, and self-grooming, were monitored 20 min following the morning and afternoon milk replacer consumption, and at the same times after weaning. There were no differences in final BW and starter DMI between treatments. The decrease of average daily gain (ADG) during the week following weaning was more pronounced in GP than in IP calves. Serum NEFA concentration increased at the beginning of the study in IP calves but serum urea concentrations were greater in GP than in IP calves the week after weaning. Self-grooming increased in both treatments throughout the study but GP calves increased non-nutritive oral behaviour and decreased cross-sucking and inter-sucking behaviours throughout the study. Rearing calves in groups following an enhanced-growth feeding programme did not increase starter intake. Furthermore, cross-sucking and inter-sucking behaviours in calves reared in groups did not seem to cause increased metabolic or immunological distress.

The effects of dietary nitrate supplementation and defaunation on methane (CH4) emission, microbial protein outflow, digesta kinetics and average daily gain were studied in lambs fed chaff containing 4.1% crude protein in dry matter. Twenty ewe lambs were randomly allocated in a 2 × 2 factorial experiment (0% or 3.1% calcium nitrate supplementation and defaunated or faunated protozoal state). Nitrate supplementation increased blood methaemoglobin concentration (P < 0.05), rumen volatile fatty acids, ammonia concentration, dry matter intake, microbial protein outflow, average daily gain, dry matter digestibility, clean wool growth and wool fibre diameter (P < 0.01). Nitrate increased CH4 production (g/day) due to greater dry matter intake, but did not affect CH4 yield (g/kg dry matter intake). Nitrate-supplemented lambs had a shorter total mean retention time of digesta in the gut (P < 0.05). Defaunation reduced CH4 production and CH4 yield by 43% and 47%, but did not cause changes in dry matter intake, microbial protein outflow, average daily gain or clean wool growth. Defaunation decreased total volatile fatty acids and the molar percentage of propionate, but increased the molar percentage of acetate (P < 0.05). Interactions were observed such that combined treatments of defaunation and nitrate supplementation increased blood methaemoglobin (P = 0.04), and decreased CH4 yield (P = 0.01).
