High Level

Fifty steers were fed ad libitum for 127 days to evaluate the effect on animal performance and nutrient digestibility of the addition of rapeseed meal and rapeseed gum to a feedlot ration containing a high level of barley. There were no beneficial responses (P > 0.05) in nutrient digestibility, feedlot performance or carcass characteristics when 5% rapeseed meal was added to a high-barley diet containing 10.8% crude protein. The addition of 0.1, 0.2 or 3% rapeseed gum to the diet also had no significant (P > 0.05) effect on any of the parameters measured.

AbstractFour diets, barley/proprietary protein concentrate (B/PC), barley/maize gluten (B/MG), barley/rapeseed meal (B/RSM) and wheat/'rapeseed meal (W/RSM) were formulated to contain 165 g crude protein and 13·0 MJ metabolizable energy per kg dry matter. In experiment 1, all four diets were offered ad libitum to Charolais × Friesian bulls from 187 kg live weight to slaughter at about 488 kg live weight. In experiment 2, the B/PC and B/RSM were offered ad libitum to Charolais × (Hereford × Friesian) bulls from 222 kg live weight to slaughter at about 491 kg live weight. There were no significant differences between treatments in daily live-weight gain, percentage fat and lean in the live animal, slaughter weight or days on experiment in either experiment. In experiment 1, the carcasses from bulls given B/PC were 14 kg heavier than carcasses from bulls given W/RSM (P<0·05), but only 10 and 7 kg heavier than from bulls given B/MG and B/RSM respectively (P<0·05). The killing-out proportion of bulls given B/PC was significantly greater (P<0·05) than bulls given B/RSM. In experiment 2, carcass weights were similar but the killing-out proportion of bulls given B/PC were again greater (P < 0·001). It is concluded that B/MG and B/RSM were as effective as B/PC as finishing diets and that wheat can be successfully substituted for barley, when offered with rapeseed meal.

Feeding Trials

THREE feeding trials, 24 [pure Zebu and Zebu x Friesian crossbred] steers per each, were conducted to compare 4 rations [treatments) at three different periods of the year.  Four equal and randomly distributed groups of steers were put on 4 different but iso-calorie rations. Levels of crude protein varied from 21.4 to 18.9% as shown in table 1. The steers were individually fed for 56 days to effect 1.12 kg. gain per head daily.  Digestibility levels of the four rations were determined [Table 2]. At slaughter, carcass data were obtained and analysed [Table 4]. Animal performance, and economics of the feeding operation data are presented in Table 3.  Results of these studies showed that the 30-20% cotton seed rations gave significantly [P <0.001] higher total liveweight gains, slightly heavier carcasses and better grades than the other two rations.  Considering results of all the parameters measured and Federal Government of Nigeria's concerted efforts to boost grains and meat production on large scales, ration 3 should be recommended. Because, with abundant supplies of grains and regular supplies of animals, faster throughput and increased gross return per feedlot per annum are feasible.

A duplicated 4 x 4 Latin Square experiment was conducted to determine the effects of a gradually increased level of barley fibre in the diet on ad libitum grass silage intake and milk production. Barley fibre is a fibrous ethanol-starch by-product (120 g crude protein, 550 g neutral detergent fibre (NDF) and 120 g starch/kg dry matter (DM)). The four supplements, given at the rate of 6.5 kg/d on DM basis, were barley (B) and barley of which 333 g/kg (BF), 667 g/kg (FB) and 1000 g/kg (F) were replaced by barley fibre. In addition the cows were given 1 kg of rapeseed meal and 0.25 kg of mineral mixture. As the proportion of barley fibre in the diet increased there was a linear (P

Three experiments were conducted with dairy cows to determine the effects of rapeseed meal and/or urea upon ad libitum consumption of grain rations. In corn, corn–barley and barley-oat basal rations, replacement of soybean meal (10%) by rapeseed meal (12–13%) resulted in a decrease in grain intake. Substitution of 1.4% or 1.6% urea (22% or 19% of the total crude protein intake) for soybean meal also resulted in decreased ad libitum grain consumption. A combination of rapeseed meal (6%) and urea (08%) was comparable to 12% rapeseed meal in effect upon consumption but less marked than 1.6% urea. No rations containing rapeseed meal had significant effects upon milk composition or production. In one experiment, a significant decrease in production occurred through including 1.6% urea in the grain ration.

Range Test

The aim of the study was to evaluate the use of Calliandra leaves (Calliandra calothyrsus) as a protein source in the Kacang goat’s diet and as an alternative to substitute the use of soybean meal (SBM) in goat’s diets. The proportion of C. calothyrsus feed substitution and SBM is T1 = odot grass (ad libitum) + 100% SBM; T2 = odot grass (ad libitum) + 25% C. calothyrsus + 75% SBM; T3 = odot grass (ad libitum) + 50% C. calothyrsus + 50% SBM; T4 = odot grass (ad libitum) + 75% C. calothyrsus + 25% SBM; and T5 = odot grass (ad libitum) + 100% C. calothyrsus. The last 10 days, collections was conducted include total collections of feeding, the residue of the feed, and feces. The parameters observed were intake and nutrient digestibility of dry matter (DM), crude protein (CP), neutral detergent insoluble nitrogen (NDIN) (% CP), and acid detergent insoluble nitrogen (ADIN) (% CP). Data obtained from the study were analyzed using a one-way analysis of variance, then if the results show significant differences, it will be analyzed further with Duncan's new multiple range test. The results showed that C. calothyrsus substitution treatment of 25 to 100% (T2, T3, T4, T5) gives noticeable influence (P<0.05) for nutrient intakes, excretion (feces), and digested nutrients. The highest intake and digestible fraction of N-NDF, N-ADF, NDIN, and ADIN is the T5 treatment, which is the replacement of SBM with 100% C. calothyrsus (P<0.05).
