ABSTRACTThe use of cottonseed (CS) as an energy and protein supplement to high wheat-straw diets was studied in a digestion and nitrogen balance trial, and as a component in fattening diets in a feeding trial. The proportions of CS studied were 0, 60, 120, 180 and 240 g/kg diet dry matter (DM). DM intake per kg M0·75 was 33, 31, 40, 31 and 29 g, respectively. The digestibility coefficient of organic matter was 415, 463, 417, 441, 350 g/kg DM and of neutral-detergent fibre was 350, 436, 411, 309, 334 g/kg DM. Nitrogen balance was –2·52, 1·1, 5·38, 5·63, 7·60 g/day respectively, for the same order of treatments. The effect of high proportions of CS in the diet in restricting DM intake and reducing its digestibility was evident. The results of the feeding trial were in agreement with those of the digestion trial and indicate the proportion of 120 g CS per kg DM as optimal and maximal.

The objective of this study was to determine the bioavailability of selected minerals from Maize Germ Oilcake. Fifteen Karan Fries male calves of 6-12 months of age were selected and given 1.3, 1.7 and 2.1 kg/d of maize germ oilcake (MGOC) along with 1.7, 1.3 and 0.9 kg/d of wheat straw (WS) in three groups of 5 animals each for 21 days of adaptation period followed by 7 days of metabolism trial. Digestibility of dry matter (DM), organic matter (OM), ether extract (EE) and neutral detergent fibre (NDF) varied significantly between the groups. Apparent absorption values of Calcium (Ca), Phosphorus (P), Magnesium (Mg), Iron (Fe), Manganese (Mn), Cobalt (Co), Copper (Cu), Molybdenum (Mo) and Zinc (Zn) for maize germ oil cake were in the range of 51.31-56.32%, 44.16-46.16%, 46.09-46.75%, 8.39-12.73%, 7.21-9.59%, 3.38-5.18%, 25.26-27.84%, 46.45-48% and 25.54-26.49%. Addition of maize germ oil cake at varying levels did not have variations in the apparent absorption of minerals.

Eight Friesian calves, 8 weeks of age, were prepared with rumen and abomasal cannulae. Four calves were given lucerne and four calves were given wheat straw sprayed with urea and minerals. The diets were changed over between the calves every 6 weeks until the calves were 56 weeks of age. The particles in the rumen that passed through a 1 mm screen during wet sieving were 66 to 73% of the total particles in the rumen of calves given lucerne and 77 to 84% of the particles in the rumen of the calves given wheat straw. The digestion of organic matter in the stomach was 71 to 79% of the total organic matter digested in the calves given lucerne. In the calves given wheat straw, between 82 and 95% of the total organic matter digestion occurred in the stomach. The apparent digestion of dry matter in the calves given lucerne was 61-6856 and did not change with age of the calves. The apparent digestion of dry matter when the calves were given wheat straw was 42% at 14 weeks of age, and it increased to 53% at 56 weeks of age. The digestion of nitrogen in the intestine in the heifers given wheat straw increased to 26 weeks of age while that of heifers given lucerne hay decreased.

Rumination and activity behaviours are important welfare indexes in beef-cattle housing. The main objective of the present study was to assess whether the automatic collars are able to reliably assess the rumination and activity patterns of beef heifers. For this purpose, individual rumination time and activity (RT and AT respectively) were continuously recorded using an automatic neck-collar system (Hr-Tag, SCR Engineers Ltd, Israel) on the three trials performed. For Experiment 1, 60 Italian crossbred heifers were randomly assigned to one of two experimental diets for 9 months: the corn–silage diet (CS), which included 50% forage on a dry-matter (DM) basis (43% corn–silage, 7% wheat straw) and the hay diet (HAY), with 57% forage on DM basis (28.5% grass hay, 28.5% alfalfa hay). Heifers consuming HAY diet showed greater (P < 0.05) RT (min/day) and AT (bits/day) than did those on CS diet. Rumination time per kilogram of dry matter and per kilogram of amylase- and sodium sulfite-treated neutral detergent fibre corrected for ash residue (aNDFom) intake were similar in the two experimental groups, while RT per kilogram of physical effective NDF (peNDF) intake was greater (P < 0.05) in the CS group than in the HAY one. Daily rumination and activity patterns (min/2 h and bits/2 h respectively) were significantly different between CS and HAY groups. In the second experiment, 32 beef heifers were randomly allocated in two homogeneous pens, each containing eight animals, and two non-homogeneous ones, in which animals were added at different periods. The AT of non-homogeneous pens was significantly higher than that of the homogeneous ones, suggesting a distress condition for values higher than 309 bits/day AT. In the third experiment, RT and AT of three animals with respiratory disease were collected using the automatic collar system and compared with AT and RT of the healthy animals. Sick animals presented a significantly lower RT and higher AT than did the healthy ones. The cut-off to distinguish sick from healthy heifers was set to 537 bits/day AT and 381 min/day RT. In conclusion, the present study demonstrated that automatic collars can reliably monitor different rumination and activity behaviours of beef animals in various management conditions and different health statuses.

The Uk

Grass silage forms the basal forage for the majority of dairy and beef cattle during the winter indoor feeding period. However its feeding value, as determined by intake potential and digestibility can differ dramatically at farm level as indicated by the Hillsborough Feeding Information System (HFIS). For example, for 7000 silages which were offered to dairy and beef cattle during the 1999/2000 indoor feeding period in Ireland and analysed through the HFIS, dry matter digestibility (DMD) varied from 540 to 830 g/kg DM (Keady, 2000). Many models used to predict feed intake by dairy cattle include a digestibility component (Keady and Mayne, 2000). However some models use DMD whereas others use digestible organic matter digestibility (DOMD). Furthermore commercial laboratories in Ireland measure silage digestibility as DMD while in the UK it is measured as DOMD. To facilitate the use of different models to predict food intake by dairy cattle, often it is necessary to be able to predict DMD from DOMD or vice versa. The present study was undertaken to develop a relationship between DMD and DOMD to facilitate the use of different models for the prediction of food intake when digestibility is available only either as DMD or as DOMD.

ABSTRACTWheat straw treated with 35 g NaOH per kg was offered to male calves at three levels: 300 (A), 500 (B), and 700 (C) g/kg diet, in a metabolism trial and in a feeding trial. In the former the wheat straw was offered either neutralized with HC1 (N) or unneutralized (U), in six subtreatments (AN, BN, CN, AU, BU and CU) in a 3 × 2 factorial design to a total of 24 calves. Dry-matter intake per kg W0·73was 123, 108, 104, 122, 105 and 91 g/day, and the digestibility of the organic matter of the straw was 0·388, 0·616, 0·629, 0·385, 0·528 and 0·544 respectively. The apparent digestibility of the crude protein of the straw was negative. Nitrogen retention per kg W0·73was 0·91, 0·58, 0·52, 0·97, 0·57 and 0·50 g/day, respectively.In the feeding trial, unneutralized, NaOH-treated wheat straw was offered to a total of 84 calves for 100 days at the above three levels with two protein levels: standard, 120 g/kg (S) and high, 140 g/kg (H), in six subtreatments (AS, BS, CS, AH, BH and CH) in a 3 × 2 factorial design. The concentrates were pelleted. From day 101 to slaughter all the calves were offered one finishing diet.Level of protein had no effect on performance. Increasing the levels of straw in the first 100 days sharply reduced average daily gains; these were 1 074, 825 and 583 g, respectively. However, the respective average daily gains on the finishing diet were 1 131, 1 272 and 1 316 g, indicating a considerable amount of compensatory growth.

Sunflower Cake

 The objective of this study was to evaluate the effect of the inclusion of sunflower cake replacing soybean meal in beef cattle diets on the in vitro digestibility of dry matter (IVDDM), organic matter (IVDOM), crude protein (IVDCP) and the ruminal fermentation kinetics and parameters. The experiment was analyzed according to a completely randomized design. The treatments consisted of four levels of sunflower cake, 0, 200, 400, 600 g kg-1, replacing soybean meal in the concentrate of beef cattle diets. The coefficients of IVDDM, IVDOM and IVDCP presented a quadratic effect with the addition of sunflower cake. The soluble fraction (fraction B) degradation rate and total gas production decreased linearly with the inclusion of sunflower cake. Values of pH in ruminal fluid were higher for levels 0, 200 and 600 g kg-1 sunflower cake. Sunflower cake can replace soybean meal by up to 280 g kg-1 in the concentrate of beef cattle diets, improving the in vitro digestibility of dry matter organic, matter and crude protein. Levels above 400 g kg-1 reduce ruminal digestion rate, digestibility and release of final fermentation products.

Feed Value

Two separate experiments were conducted to compare the nutrient digestion and growth performance of beef cattle fed diets containing up to 77% of two conserved alfalfa hays. The two alfalfa hays were baled either at the optimum moisture (8.6%) or at a higher-than optimum moisture (21.4%) with application of a mixture of Pediococcus pentosaceus and chitinase at baling. Digestibility of dry matter, neutral detergent fibre, acid detergent fibre, rumen parameters, and growth performance were similar (P ≥ 0.16) for cattle fed either diet. A combination of P. pentosaceus and chitinase has the potential to preserve high-moisture alfalfa hay.

Chewing Activity

Our aim in this study was to determine the effects of physically effective neutral detergent fibre (peNDF) in a total mixed ration (TMR) on feed intake, digestibility and chewing activity in beef cattle. The experiment had a replicated 3 × 3 Latin square desig, using three fattening Hanwoo (Bos taurus coreanae) steers with ruminal cannulas. Steers were offered one of three diets (high, medium or low peNDF content) obtained by mixing the same TMR for different periods of time (5, 13 and 25 min). peNDF content of TMR was calculated as [total chewing time/NDF intake (kg)] × dietary NDF content, and the proportion of sample dry matter (DM) collected in a ≥1.18-mm sieve is commonly used as the physical effectiveness factor in the equation. The peNDF1.18 contents of the high, medium and low diets were 25.97%, 21.10% and 17.94% (P < 0.05). In addition, the proportion of particles collected on the 19-mm, 1.18-mm, and pan sieves changed linearly with an increase of TMR mixing time. Mean particle-size distributions of diets were 11.43, 24.11, 30.70 and 33.68 for 19 mm, 8 mm, 1.18 mm and pan, respectively. Eating rate and ruminating and chewing efficiencies were significantly decreased with reduced peNDF content, and DM intake was increased significantly (P < 0.05). Lower peNDF content reduced the total number of chews significantly (P < 0.05). Total time spent chewing associated with eating was not affected by peNDF contents. Digestibility of DM, crude protein and crude fat decreased with reducing peNDF content in the diet, but there was no significant difference among the three groups. These results indicated that peNDF affects intake, digestibility and chewing activity in beef cattle. Therefore, high levels of peNDF appears to improve TMR, as it can increase efficiency and may prevent ruminal disorders in Hanwoo steer.

AbstractA feeding trial with growing sheep was conducted on mixed roughage-supplement diets, to test whether roughage intake could be estimated from a known intake of a supplement and an alkane-based estimate of the supplement and roughage proportions in the diet (diet composition) without the need for separate dosing with external marker alkanes. Diets consisted of chaffed Trifolium subterraneum hay (SC), or a mix of SC and beeswax-labelled cottonseed meal (CSM) in the proportions of 7: 1, 6: 2, 5: 3 and 4: 4 (air-dry matter basis). Six sheep were given the pure SC diet and three sheep were given each of the mixed diets. Additionally, the CSM was also labelled with octatriacontane (C38) to investigate its use for labelling supplements. Due to unexpectedly low recoveries, C38 was not included in any estimation of diet composition or digestibility.The inclusion of beeswax-labelled CSM in a SC diet resulted in lower faecal alkane recoveries (as proportions of alkane ingested; P ≤ 0·05). Within mixed diets, recoveries decreased significantly with increasing proportion of CSM, but this effect was significant (P < 0·05) only for alkanes consisting of 25, 26, 27 and 29 carbon-atoms. Estimates of diet composition were close to measured values. Daily SC intake and organic matter digestibility (OMD) differed by −3·7 to 7·2% and −2·0 to 5·7% from measured values if a mean faecal recovery, across diets, was applied for each alkane. Accuracy increased greatly if estimates were based upon faecal alkane recoveries for individual diets, instead of mean recoveries across diets (−0·3 to 0·9% and −0·2 to 0·0% for SC intake and OMD, respectively).The results indicate that roughage intake can be estimated from a combination of known supplement intake and an estimate of diet composition, which obviates the need for separate alkane dosing to estimate intake. The method should be applicable in situations in which animals either normally receive supplements (e.g., dairy cows) or could readily be given supplements.
