<p>An experiment was carried out to investigate the efficiency of dietary energy utilisation in. Ongole Grade (OG) and OG x Limousin (OGL) young bulls under intensive feeding regime. This experiment used 4 OG and 4 OGL young bulls (about 6 months old). The initial body weight of OG was 78±4.69 kg, and that of OGL was 91.25±12.62 kg. This experiment used “Independent Sample Comparison” method. Parameters observed were energy intake, energy digestibility, energy metabolisability, live weight gain and energy conversion. The results showed that dry matter (DM) intake of OG PO (26.87 g/ kg BB) was lower (P&lt;0.05) than that of OGL (33.05 g/ kg BB/d); so that energy intake of OG (0.43 MJ/kg BB/d) was also lower (P&lt;0,05) than that of OGL (0.55MJ/kg BB/d).However, were not significant difference (P&gt;0.05) between the two breeds in all other parameters observed. Dietary energy digestibility’s in OG and OGL were 52.60 and 52.20%, respectively. Energy metabolisability’s in OG and OGL were 44.30 and 42.90%, respectively. Live weight gain of were 0.325 and 0.412 kg/d in OG and OGL, respectively Energy conversions in OG and OGL were 46.44 and 55.90 MJ per kilogram live weight gain.

Parameters observed were energy intake, energy excretion through faeces, urine and methane, and live weight gain. The results showed that there was no significant difference (P&gt;0.05) between OG and OGL in energy intake (58.2 MJ/d vs 74 MJ/d), nor in energy metabolisability (38,4% vs 43,4%) The LWG of OG (0,24 kg/d) was significantly (P&lt;0.5) lower than that of OGL (0,47 kg/d).

ABSTRACT1. A primary growth of perennial ryegrass was cut on 8 to 11 May (early) or on 12 June (late) for comparison with the primary growth of a tetraploid red clover, which was cut either on 1 or 2 June (early) or on 28 June (late). The crops were ensiled, after wilting for about 4h, with the addition of formic acid at 2·21/t fresh crop. The silages were given ad libitum alone or with rolled barley at 11·5 g dry matter per kg live weight to 40 British Friesian steers initially 3 months old and 108 kg live weight.2. On average there was no significant difference in digestibility between perennial ryegrass and red clover. However, the rate of decline in digestibility with time was greater with perennial ryegrass than with red clover.3. Calves given silage of red clover as the sole feed ate more dry matter and grew faster than calves given grass silage (P <0·001) but supplementation with barley reduced the intake of red clover silage to a greater extent than that of perennial ryegrass silage. Barley supplementation increased live-weight gain of calves given perennial ryegrass from 0·32 to 0·83 kg/day and that of calves given red clover from 0·63 to 0·99 kg/day (interaction P <0·05). The results did not indicate a higher net efficiency of utilization of the legume. Date of cut had no significant effect on dry-matter intake but earlier cutting resulted in an increase in live-weight gain from a mean of 0·61 to 0·77 kg/day (P <0·001).4. The results show that high rates of live-weight gain (0·74 kg/day) can be achieved by calves given silage of red clover and that earlier cutting of herbage for silage does not always result in higher intakes of dry matter. Supplementation of silages with barley can reduce markedly the difference in intake and live-weight gain apparent when the silages are given as sole feeds.

ABSTRACTGroups of Hereford-cross steers weighing 283 kg were given 0·6 kg dry matter hay per head per day, and bruised barley supplemented with 40 g of a fully soluble liquid product per kg, containing urea, minerals and vitamins, ad libitum. Half the animals received 10 g limestone per kg diet as an additional supplement. Over a 105-day period the food intake of the limestone-supplemented animals was 0·20 higher than that of unsupplemented animals. The resultant daily live-weight gain was 1·22 kg compared with 0·92 kg for the animals receiving the diet containing no additional limestone. Food conversion ratios (kg/kg live-weight gain) were improved by limestone supplementation from 6·84 to 6·19. Limestone inclusion did not appear to influence the low concentrations of starch (ca. 15 g/kg) present in the faecal dry matter but there was a small significant difference in faecal pH.

In a feeding trial with 18 calves, three carbohydrate additions were compared in a liquid milk replacer diet: glucose, xylitol and polyol molasses (PM). The average consumption of substrates was 41, 42 and 48 g dry matter of glucose, xylitol or polyol molasses per day. After one week of colostrum and whole milk feeding, liquid milk replacer was given 12 % of live weight. The trial lasted to the age of 5 weeks. Daily live weight gain was 452, 479 and 425 g in the glucose, xylitol and PM groups(n.s.), respectively. Intake of concentrates was greater in female than male calves (P < 0.05). There was no significant difference in the feed conversion rate between the groups: 1.83, 1.88 and 1.98 kg dry matter/kg live weight gain in the glucose, xylitol and PM groups, respectively. Venous blood samples were taken before the first feeding after birth, then 1, 2, and 4 days, and 1, 3 and 5 weeks after birth. Haemoglobin and haematocrit were higher in the glucose than in the xylitol and PM groups, and higher in female than male calves (P < 0.05). There were no differences between the groups in plasma glucose, calcium or magnesium contents. Plasma urea-N was lower in the xylitol than in the glucose group (P < 0.05). Plasma inorganic phosphorus was higher in the xylitol than in the glucose group on week one and three after birth, the difference being significant at 3 weeks of age (P < 0.05).

SUMMARYIn two experiments dried grass cobs or concentrate were offered to calves for 20 weeks after weaning. In Experiment 1 the grasses were harvested in the autumn and in Experiment 2 in the spring. Within each experiment three grasses differing in quality and two levels of concentrate were compared.Dry-matter intake of the dried grasses highest in digestibility was lower than that of medium digestibility grass, and hardness of package, palatability and mould infestation were implicated as possible causal factors.Live-weight gains by calves were closely correlated with digestible organic matter (DOM) intake. There was no significant difference between spring harvested grasses and concentrate in efficiency of utilization of DOM for live-weight gain but autumn grasses were used less efficiently than concentrate. At similar rates of gain the replacement value (dry-matter basis) of dried grass for concentrate averaged 142: 1.

The aim of our study was to test whether a reduction in dietary intake could improve in vitro embryo production in superovulated overfed dairy heifers. Cumulus–oocyte complexes of 16 Prim’ Holstein heifers (14 ± 1 months old) were collected by ovum pick-up (OPU), every 2 weeks following superovulation treatment with 250 μg FSH, before being matured and fertilized in vitro. Embryos were cultured in Synthetic Oviduct Fluid medium for 7 days. Heifers were fed with hay, soybean meal, barley, minerals and vitamins. From OPU 1 to 4 (period 1), all heifers received individually for 8 weeks a diet formulated for a 1000 g/day live-weight gain. From OPU 5 to 8 (period 2), the heifers were allocated to one of two diets (1000 or 600 g/day) for 8 weeks. Heifers’ growth rates were monitored and plasma concentrations of metabolites, metabolic and reproductive hormones were measured each week. Mean live-weight gain observed during period 1 was 950 ± 80 g/day (n = 16). In period 2 it was 730 ± 70 (n = 8) and 1300 ± 70 g/day (n = 8) for restricted and overfed groups respectively. When comparing period 1 and period 2 within groups, significant differences were found. In the restricted group, a higher blastocyst rate, greater proportions of grade 1–3 and grade 1 embryos, associated with higher estradiol at OPU and lower glucose and β-hydroxybutyrate, were observed in period 2 compared with period 1. Moreover, after 6 weeks of dietary restriction (OPU 7), numbers of day 7 total embryos, blastocysts and grade 1–3 embryos had significantly increased. On the contrary, in the overfed group, we observed more <8 mm follicles 2 days before superovulation treatment, higher insulin and IGF-I and lower nonesterified fatty acids in period 2 compared with period 1 (no significant difference between periods for embryo production). After 6 weeks of 1300 g/day live-weight gain (OPU 7), embryo production began to decrease. Whatever the group, oocyte collection did not differ between period 1 and 2. These data suggest that following a period of overfeeding, a short-term dietary intake restriction (6 weeks in our study) may improve blastocyst production and embryo quality when they are low. However, nutritional recommendations aiming to optimize both follicular growth and embryonic development may be different.
