Japanese quail (Coturnix coturnix japonica) usually fed on ground or pelleted balanced feeds, while whole grains are supplied in alternative systems. Voluntary intake and preference of four whole-grain cereals (durum wheat, bread wheat, triticale and barley) were assessed in Japanese quails. Two experiments were performed: (i) a trial with five batches of six randomly selected quails (three males, three females) allocated to each treatment consisting of one cereal or a balanced feed (control) in the voluntary intake experiment; and (ii) a trial with four bird batches receiving simultaneously the four cereals in the preference experiment. Three repetitions of each trial were performed. When feedstuffs were provided as a sole feed, voluntary feed intake differed, being the highest in quails fed the balanced feed (20.0 g/d), intermediate for durum wheat (15.0 g/d), bread wheat (15.8 g/d) or triticale (15.6 g/d), and the lowest for barley (12.1 g/d). Voluntary intake did not differ between sexes. Positive correlations existed between voluntary feed intake and live weight of quails, being the highest and very strong for the balanced feed, moderate for durum and bread wheat and barley, and weak for triticale. The preference trial showed that quails preferred durum wheat (7.1 g/d), triticale (4.0 g/d), bread wheat (3.0 g/d) and barley (0.3 g/d) in descending order, independently of sex. Positive correlations existed between daily feed intake and live weight of birds for durum and bread wheat. Strong positive correlation existed between bird live weight and total intake when the four cereals were available simultaneously. Differences in voluntary intake and preference among whole-grain cereals should be take into account when used to feed quails.

Voluntary Intake

SUMMARYVoluntary hay intake and milk yield were measured in 11 singlesuckling and 4 twin-suckling ewes for the first seven weeks of lactation. There was no significant difference between the intakes of the two classes of ewe and milk yield differed only in the seventh week. Variations in milk yield and live-weight change were significantly associated with variations in voluntary intake. Lamb weight gain was correlated with milk yield and voluntary intake of the dam.

1. Voluntary feed intake, performance and carcass quality were studied with 20 individually housed pigs given isocaloric diets (2,770 kcal/kg. DM) containing either 8·9 % or 12·9 % crude fibre in the dry matter over the period of growth from 45 to 91 kg. live-weight.2. There were no significant differences between diets in voluntary feed intake, rate of gain or carcass quality.3. Apparent digestibility coefficients and rates of passage of the diets were determined in eight castrated male pigs. Rates of passage were not significantly affected by diet or live-weight when determined at 57 and 82 kg. live-weight.

Voluntary Intake

Disposal of sewage sludge to grassland is likely to increase in future years as a result of legislation to control disposal to the sea (CEC, 1991) and increased production (DoE, 1993). Recent research has investigated the possible accumulation of potentially toxic elements in body tissues of lambs given diets containing known amounts of sludge (Wilkinson et al, 1996). The aim of this experiment was to study the effects of season and method of application of sludge to grassland on voluntary feed intake, digestibility and growth of lambs.

Three sheep with permanent fistulas of the rumen were each given dried grass and two hays, each in three different amounts, and the apparent digesti-bility of the roughages in the rumen and distal to the rumen was determined. A lignin ratio method was used to measure digestibility.With increase in the amount of the poorest hay given, the proportion digested in the rumen fell and that distal to the rumen increased. With the second hay this effect was also noted but was not statistically significant. The voluntary intakes ofdry matter varied from 1·94 kg/day for the dried grass to 1·28 for the poorest hay. The volumes of distribution of polyethylene glycol in the rumen when feed was offered ad libitum, however, were the same, irrespective of the type of feed, at between 14·1 and 15·2 litres. These observations were confirmed at slaughter. The results support the hypothesis that sheep voluntarily consume roughages of different qualities to achieve constant fill of their rumens, and that little regulation of voluntary intake can be attributed to distension of the hind gut.

Abstract In the United States, bioethanol is generated from corn and biodiesel from soybean oil to reduce the dependence on fossil fuels. Ethanol production generates DDGS, high in bypass protein and soluble carbohydrates, which can be used as a cheaper alternative replacement for corn and soybean. This experiment was conducted to evaluate voluntary feed intake, body weight gain and blood metabolites of lambs fed legume-based diets supplemented with corn and soybean meal or dried distillers grain with solubles (DDGS). Animals were individually housed in pens (1.52 mx 1.52 m) under a modified carport shed with woodchips as bedding. They were stratified into four groups (n = 9) with similar weights and standard deviation and randomly assigned to four treatments. The lambs were fed ground sericea hay (SL) or alfalfa meal (ALF) with either corn and soybean meal (control) or DDGS for 60 days. Treatments were SLC, SLDDGS, ALFC and AFLDDGS. The lambs were fed ad libitum based on their selected treatment and given water daily. At the end of the 60 days, weights and blood samples were collected. Plasma samples were analyzed for blood urea nitrogen (BUN), glucose and non-esterified fatty acids (NEFA). Data were analyzed using Proc Mix Procedure of SAS. Results indicated that replacing corn with DDGS did not (P > 0.05) affect voluntary feed intake, final live weight and carcass weight. Blood NEFA and glucose were not affected by dietary treatments. BUN increased in lambs fed alfalfa with corn and soybean meal compared to animals fed either legume supplemented with DDGS. Similarly animals fed sericea have lower (P < 0.05) BUN (19 vs 23 mg/dL) when corn and soybean meal were replaced with DDGS. DDGS can be used in legume diets for growing lambs in replacement for corn and soybean meal.

SUMMARY1. Estimates of the voluntary feed intake of three age groups of wether sheep on ryegrass and white clover pasture from July to October, 1962, were made by total collection of faeces and the use of local faecal nitrogen-digestibility regressions.2. Average faecal output and intake of digestible organic matter (DOM) increased with age of the sheep. However, relative to body weight (W) or to W073, the aged sheep (5 years old), which did not change much in weight over the period, consumed only about two-thirds of the DOM consumed by the younger (sixteen- and four-month-old) growing sheep.3. For the growing sheep intake was directly related to weight. Intake was calculated to be 24 W (kg.)–28 ±108 g. DOM per day.4. The results are discussed in relation to the errors in estimation of digestibility. Comparison of the intake estimates with other published data suggests there was a high apparent maintenance requirement. The voluntary feed intakes observed, when expressed as g. dry matter per kg. W0–73, were somewhat higher for young sheep but lower for aged sheep than estimates of previous authors.

Autumn And Winter

Subcutaneous melatonin implants were administered to castrated hand-reared male red deer (Cervus elaphus) during a 63 d period in spring, after which effects on voluntary feed intake (VFI), rumen pool size, rumen capacity (i.e. volume) and heart rate were measured on four occasions, evenly spread over a 12-month period, with the deer individually fed indoors on a diet of lucerne (Medicago sativa) chaff. Blood samples for hormone determinations were taken at intervals throughout the study. Day-time plasma melatonin concentration was approximately 5 pg/ml in control animals, whereas during melatonin administration it increased to 60–150 pg/ml and declined to 30 pg/ml by 142 d after the last implantation. Melatonin administration markedly depressed plasma prolactin concentration during the period of implantation, but thereafter plasma prolactin concentration rose in the treated animals during autumn and winter, whilst it declined in control animals over this period. VFI, rumen pool size and heart rate in control animals attained highest values in summer and lowest values in winter, showing a pronounced seasonal cycle. Melatonin administration depressed all these values in late spring and summer and increased all the values in autumn and winter, relative to control animals, and appeared to move the cycles by approximately 6 months. Melatonin-treated animals showed maximum values for all these measurements during winter. The castrated male deer showed little seasonal change in live weight, which was not affected by melatonin administration. The findings support the view that melatonin probably mediates the effect of daylength on digestive function in red deer. Rumen capacity remained relatively constant throughout the year, but rumen pool size as a proportion of rumen capacity increased with increasing VFI.
