Oilseed rape meal is high in protein and available in the UK relatively cheaply. Toxic constituents limit its inclusion in feeds for pigs and poultry but this is not a problem with ruminant animals where microbial action in the rumen removes them. However, the bitter taste of rape meal has been thought to reduce its palatability for ruminant animals (Stedman and Hill, 1987) and it is recommended that its inclusion in compound feeds for cows should not exceed about 150kg/tonne; masking agents are incorporated to reduce this limitation.The question to be addressed can be summarized as “can higher rates of inclusion of rape meal in dairy compound feeds be concealed by more mask?”. Twelve dry cows in late pregnancy were offered feeds with various levels of rape meal in combination with several levels of mask and rate of consumption was monitored.

Current suggestions for the upper limit for the total gucosinolate content of oilseed rape are around 20 μmol/g of seed, which corresponds to a level in the de-fatted meal of approximately 33 μ mol/g. Information about the suitability of this material for incorporation in growing pig diets is required by the UK feed industry. When attempting to provide the required information the presence of factors such as tannins, sinapine and phytate in rapeseed meal should be considered, as must the high (≈ 120 g/kg) fibre content of the material. This experiment was designed to examine growing pig performance from 30 to 75 kg liveweight when fed diets containing increasing levels of rapeseed meal at both fixed and increasing glucosinolate contents.

Oilseed rape is currently the third most important crop in the UK after barley and wheat. Field experiments show that despite the already attractive yields the full potential of the crop has not yet been achieved. However, its future is uncertain in that the area devoted to it within the EEC—representing one-fifth of world production—is strongly influenced by the financial incentives offered. It is suggested that within the Community output should be limited to 3.3m tonnes p.a. for the next five years.

Bitterness Masking

Abstract Many functional food ingredients activate human bitter taste receptors (hTAS2Rs). In this study, A novel inhibitor, Trp-Trp, for hTAS2R14 was identified by searching for the agonist peptide's analogs. Trp-Trp also inhibited hTAS2R16, hTAS2R43, and hTAS2R46, which share the same agonists with hTAS2R14. The multi-functional characteristic of Trp-Trp is advantageous for use as bitterness-masking agents in functional foods.

Ewes fed good quality grass silage need low levels (0.4-0.6 kg/d) of concentrate supplement to satisfy energy requirements in late pregnancy. However, the UK Metabolisable Protein (MP) system predicts that using a low level of a typical 180 g/kg crude protein (CP) compound will result in an undersupply of MP and therefore a higher digestible undegradable protein (DUP) content of compounds is required. Although the benefits of supplying additional DUP to lactating ewes are well established there is little or no experimental evidence to support the practice of supplementing silage based diets with supplementary DUP. The objective of the experiment was to evaluate the response to supplementary DUP in silage based diets.One hundred and twenty five scanned Scotch Mule ewes were synchronised, mated to Texel rams and allocated to 5 treatments balanced for liveweight, condition score, litter size, and parity. Five supplements were formulated to supply varying amounts of DUP and eRDP.

The effectiveness of antenatal intervention in women with increasing obesity is unknown. This study investigated whether there was a differential effect of antenatal intervention on diet, physical activity and pregnancy outcomes in women stratified by obesity class using data from the UK Pregnancies Better Eating and Activity Trial (UPBEAT) (n = 1555). The stratification was by World Health Organization classifications: Class I, II and III (30–34.9 kg/m2, 35–39.9 kg/m2 and ≥40 kg/m2). Using linear and logistic regression, adjusted for confounders, outcomes were assessed post-intervention (27+0–28+6 weeks’ gestation) and in late pregnancy (34+0–36+0 weeks’ gestation). Interactions between obesity class and the intervention were explored. Compared to the standard care arm, class III intervention women had lower gestational weight gain (GWG) (−1.87 kg; 95% CI −3.29 to −0.47, p = 0.009), and the effect of the intervention was greater in class III compared to class I, by −2.01 kg (95% CI −3.45 to −0.57, p = 0.006). Class I and II intervention women reported significantly lower dietary glycaemic load and saturated fat intake across their pregnancy. This differential effect of the intervention suggests antenatal interventions for women with obesity should stratify outcomes by obesity severity. This would inform evidence-based antenatal strategies for high-risk groups, including women with a BMI ≥ 40 kg/m2.

Low-glucosinolate rapeseed meal (<20 μmol/g) is likely to replace the high-glucosinolate meal currently produced in the UK, and in this experiment the use of low-glucosinolate rapeseed meal (RSM) as the sole protein supplement in a compound feed for milk production in cows was assessed. There were three compound concentrate feeds of similar energy and protein content, 0% RSM (group A), 15% RSM (B) and 30% RSM (C). The additional protein in diets A and B was provided as soyabean meal (SBM).Eighteen Friesian cows were divided into three groups, balanced with regard to previous yield and number of lactations, and three weeks after calving were given one of the compound feeds in a 3x3 changeover experiment; each of the three feeding periods was four weeks. Barley meal was given as a parlour feed, 1 kg air dry at each milking, and the compound concentrate and grass silage were given at Broadbent-Calan gates in quantities related to expected milk yield.

SUMMARYThe aim of the present study was to evaluate the effects on yield, oil concentration and nitrogen (N) uptake efficiency of N fertilizer applied to the foliage of oilseed rape during and soon after flowering. Four field experiments were conducted in the UK during the 2008/09 and 2009/10 seasons which investigated six rates of soil-applied N (ammonium nitrate) ranging from 0 to 280 or 320 kg N/ha with each treatment followed by 0 or 40 kg/ha of foliar N applied as a solution of urea at the end of flowering. Each experiment also investigated five rates of foliar N ranging from 0 to 120 kg N/ha applied at the end of flowering and five timings of foliar N (40 kg N/ha) from mid-flowering to 2 weeks after the end of flowering.Foliar N at 40 kg N/ha applied at the end of flowering significantly increased the seed yield in three of the four experiments. The seed yield increase across all four experiments was 0·25 t/ha (range of 0–0·41 t/ha). In two experiments, the increase in seed yield in response to foliar N occurred irrespective of whether it followed sub-optimal or super-optimal rates of soil-applied N; in one experiment there was a greater response at sub-optimal soil-applied N rates. The foliar N treatment reduced the seed oil concentration by 11 g/kg and increased seed protein concentration by 11 g/kg. Similar yield responses were observed for foliar N applications between mid-flowering and 2 weeks after the end of flowering. The efficiency with which foliar N was taken up into the plant varied between 0 and 100% with an average uptake efficiency across the four experiments of 61%.

Trace element deficiencies have been reported throughout the UK and are known to decrease the productivity and welfare of animals. Selenium deficiency is characterised by muscular myopathy, white muscle disease or stiff lamb disease. Subclinical deficiencies can also cause reduced growth rate and impaired immune function. In ruminant animals, cobalt is required for the synthesis of vitamin B12 and deficiency leads to Pine, characterised by emaciation, anaemia and listlessness. Trace element deficiencies can be due to either a single element or multiple elements. Situations occur particularly in sheep where cobalt and/or selenium are deficient but where copper supplementation can be toxic. To correct these deficiencies, a single long-lasting and effective treatment in the form of a soluble glass bolus has been designed to release cobalt and selenium. This new bolus is similar to the commercial Cosecure® bolus, which is a Co/Se/Cu soluble glass, in which zinc replaces the copper.
