Results of the study of the effect of the level of nondegradable protein in diet on fattening performance and digestibility of nutrients in weaned lambs are presented in the paper. Objective of the study was to establish the optimal level of non-degradable protein in diets for weaned and intensively fattened lambs. Experiment was conducted on 60 lambs of F1 generation: Pirot Pramenka x Wurttemberg x Ile de France, weaned at the age of 60 days and divided into three groups. The effect of use of three concentrated mixtures which differed in the share of protein non-degradable at the level of rumen: 43% (I), 51% (II) and 58% (III). Average daily gain of lambs fed types of mixtures I:II:III was 0.169: 0.205 : 0.227 kg, respectively. Dry matter conversion (kg/kg of gain) on analogue treatments was: 4.54 : 3.71: 3.30, respectively, of energy (MJ NEM/kg) : 33.77: 29.37 : 26.25, and of total proteins (g/kg): 732 : 596 : 549. Level of intake of proteins was not influenced by the treatment considering that the digestibility coefficients recorded were: 52.58% : 51.30% : 55.12%. With the increase of the share of non-degradable protein in concentrate mixtures, the tendency of increase of the digestibility of fat was present: 76.13 : 77.98 : 87.17%, as well as of decrease of the intake of fibre: 67.40 : 45.87: 22.39% and NFE: 83.87 : 76.05 : 82.96%. Values of the dressing percentage of warm carcass with giblets according to nutrition types I:II:III were: 58.70 : 58.02 : 57.42%, respectively.

Abstract Four hundred and thirty-two beef steers (346.3 ± 63.7 kg BW) were used to determine the effects of Zn source on feedlot cattle fed ractopamine hydrochloride. Cattle were blocked in groups of 54 by BW and housed in 48 pens containing 9 steers per pen. Pens within a weight block were randomly assigned to treatments in a 2 x 3 factorial arrangement, with factors being: 1) 0 or 30.1 mg of ractopamine HCl/kg DM fed during the final 29 days on feed; and 2) Zn source: 90 mg of supplemental Zn/kg DM from ZnSO4; Zn sulfate (67%) + Zn methionine (33%); and Zn from Zn hydroxychloride, fed through the entire feeding period. Cattle were fed a high concentrate finishing diet for 154 d and slaughtered at a commercial abattoir. Average daily gain, DMI, feed efficiency and carcass characteristics were determined after slaughter. Zinc source had no impact on live animal performance. Cattle fed ractopamine HCl had greater (P < 0.01) final BW, greater (P < 0.001) ADG, improved (P < 0.001) G:F, heavier (P < 0.01) HCW, and larger (P < 0.05) longissimus muscle compared to non-ractopamine supplemented steers. There was a Zn source by ractopamine interaction (P < 0.01) for dressing percentage. Cattle receiving ractopamine HCl with Zn hydroxychloride had a greater dressing percentage (P < 0.05) when compared to ractopamine HCl cattle fed other Zn sources. Cattle receiving ractopamine HCl with Zn sulfate had a lesser dressing percentage (P < 0.05) when compared to ractopamine HCl cattle fed other Zn sources. Additional Zn source by ractopamine HCl interactions were not significant. These data indicate that Zn source has minimal impacts on feedlot steer performance and carcass characteristics when supplemented to cattle receiving 0.0 or 30.1 mg of ractopamine HCl/kg DM.

SUMMARYA total of 70 Nellore bulls (18 ± 3 months of age) were used to determine the effects of crude glycerine (CG) replacing starch- v. fibre-based energy ingredients in low (LC; 0·40 concentrate) or high concentrate (HC; 0·60 concentrate) – on a dry matter (DM) basis – on DM intake (DMI), methane emissions and growth. Ten bulls were slaughtered (reference group) to obtain the carcass gain (CrG). The 60 remaining bulls (374 ± 24·5 kg) were allocated to a 2 × 3 factorial arrangement (two concentrate levels, LC or HC; and three feeding regimes, FR). The FR were: CO – without CG and maize as an ingredient of concentrate; CGM – inclusion of CG (0·10 of DM) replacing maize in the concentrate; and CGSH – inclusion of CG (0·10 of DM) replacing soybean hulls (SH) in the concentrate. Bulls fed LC or HC had similar DMI (kg/d) and growth. The DMI and average daily gain (ADG) were similar among FR. Concentrate level and FR tended to interact for methane emissions (g) per kg DMI. Bulls fed CGM had a greater G : F (g CrG/kg DMI) than those fed CO or CGSH diets. Increasing dietary concentrate (0·40–0·60) did not affect intake, methane emissions, or growth. Inclusion of CG in diets to replace SH in LC diets tended to decrease methane emissions from animals. When CG replaces SH in the diets, CrG and G:F (g CrG/kg DMI) are decreased compared with bulls fed CGM.

Thirty-two large-frame crossbred steers (443 ± 5 kg) were used to determine the nutritive value of cracked corn, rolled barley, rolled oats and rolled wheat in finishing diets for beef cattle fed medium-quality grass hay. Diets contained about 54% grains, 40% grass hay and 6% of a supplement of minerals, vitamins and lasalocid. Total daily dry matter (DM) intake ranged from 9.52 to 10.24 kg, average daily gain from 1.09 to 1.17 kg and gain to feed ratio from 0.113 to 0.121, but these values were not statistically different (P > 0.05). Apparent digestibilities of DM and energy of steers receiving the oats diet were lower than those of steers receiving the wheat diet (P < 0.05), the other diets having intermediate values. Apparent digestion coefficient of protein was higher for the oats diet (P < 0.05) than for other diets. Acid detergent fiber digestibility was higher (P < 0.05) and starch digestibility was lower (P < 0.05) in steers receiving corn than in those receiving barley, oats or wheat. The results indicate that nutritive value of all diets was similar. Key words: Grains, fattening steers, digestibility

This experiment was conducted to evaluate the effects of corn or soybean hull incorporation into haylage-based diets on backgrounding calf performance and subsequent feedlot performance. Crossbred steers [n = 48, initial body weight (BW) = 303 ± 3.4 kg] were individually fed dietary treatments consisting of: (1) haylage [17.5% crude protein, dry matter (DM) basis; control], (2) haylage + 20% (DM basis) cracked corn, and (3) haylage + 20% (DM basis) soybean hulls during a 112-d backgrounding period. After the backgrounding period, all steers were adapted to a common high moisture corn-based finishing diet and fed until an ultrasound estimated backfat thickness of 7 mm was obtained. During the backgrounding period, steers fed cracked corn or soybean hulls had greater (P < 0.01) average daily gain, dry matter intake and gain:feed and lower (P = 0.05) plasma urea N as compared with controls. However, when finished on a common high-concentrate diet, steers previously fed cracked corn had greater (P < 0.08) average daily gain, final body weight, and longissimus muscle area than those fed soybean hulls, suggesting that source of supplemental energy during the backgrounding period may influence subsequent feedlot performance.

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.

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.

The aim of this study was to investigate the effect of two dietary treatments (liquid creep feed (LCF) and dry creep feed (DCF)) offered during the suckling period on feed disappearance, number of eaters, and intestinal enzymatic development at weaning in an on-farm study with 347 piglets. Piglets were allocated to either the DCF or LCF treatment from day 10 to day 24 postpartum for 9 h a day. Red ferric oxide (1%) was added to the diet to categorize piglets into eating categories (good eaters, moderate eaters, or non-eaters) via faecal swabs. At weaning, 40 piglets were sampled for intestinal enzymatic development. The LCF treatment increased the dry matter disappearance from day 10–18 (p < 0.001). The percentage of good eaters, moderate eaters and non-eaters did not differ between treatments (p > 0.05). The DCF pigs displayed greater average daily gain (ADG) pre-weaning (p = 0.024), and a greater body weight (BW) at day 61 (p < 0.001). The activity of lactase, maltase and sucrase in the proximal part of the small intestine were greatest (p < 0.001) in the DCF pigs.

Four trials, involving 124 pigs, were conducted to study the effects of differing planes of nutrition on swine characteristics and to study the relative response of specific genetic groups of pigs to these differing planes. Seasonal and sex effects were also evaluated. Equalized limited feeding to a scale of 75 per cent of the U.S. N.R.C. recommended levels for bacon hogs was compared to liberal feeding wherein pigs were fed to appetite three times daily and to ad libitum feeding.Winter-fed pigs grew slower, were less efficient, had a higher dressing percentage and shorter carcasses than summer-fed pigs.As the plane of nutrition increased, average daily gains increased, feed conversion ratios were correspondingly inferior, dressing percentage rose, backfat thickness increased and area of loin and total Record of Performance score decreased.Females outgained barrows under equalized limited feeding, whereas barrows outgained females at a similar feed requirement by eating more feed under liberal feeding. Female carcasses were superior to those of barrows with a tendency for the differences to be greater under the equalized limited feeding system.Genotype × plane of nutrition interactions were significant for average daily feed consumed (P <.05), average daily gain (P <.01), length (P <.05), and total R.O.P. score (P <.01). Under equalized limited feeding pigs with the ability to gain both rapidly and efficiently tended to produce superior carcasses while under liberal feeding rapid gains seemed to reflect mainly increased feed consumption and a trend toward inferior feed conversion and fatter carcasses.
