Growth Energy

In beef cattle breeding, unlike dairy farming, the only product is a calf. Therefore, the industry's competitiveness directly depends on the annual retention from each cow and heifer calf, the preservation of calves, and the high growth energy of young animal growth throughout the rearing period. These indicators are influenced by many factors, one of which is the breeding technology. The colostrum period is the most critical; newborn calves that do not receive adequate attention at the beginning of this period die within the first two days of life or have growth retardation. Given this, it becomes urgent to establish the level of dependence between young animals' growth and the technology of keeping cows and calves during the colostrum period. The studies were performed on cows and calves of the Aberdeen-Angus breed having problems in interaction during the colostrum period due to a weak maternal instinct in cows or a sucking reflex in calves (problem pairs' cow-calf). The growth rates of bull-calves and heifers were studied: live body weight, average daily gains, absolute gains, and multiplicity of live weight gain. The factor of a new technological element - the transfer of problem pairs' cow-calf into correction sections, in the colostrum period, on the further growth of young growth was analyzed. Our studies have shown a potential difference (P=0.999) between the live weight of bull-calves, which in the colostrum period were transferred together with the cows to the correction sections, and those for which no correction sections were used. The advantage in live weight at the age of 18 months is 27% and 28% (P=0.999) in favor of bull-calves that were transferred; they prevailed by 28% (P>0.999) in average daily gains, and by 28% and 29% (P=0.999) in absolute terms. When compared by live weight at the age of 18 months, the heifers, which had been transferred to correction sections during the colostrum period, had an advantage of 26%. The average daily and absolute gains in these heifers were 29% greater than the heifers, which were not transferred.

There was studied the distribution of postpartum pathology of cows and disease of calves in early postnatal period in conditions of Nizhny Novgorod region. It was established, that the new tissue drug "bio-tec" has positive influence on reproductive function, safety and live weight gain of calves. The postpartum pathology of cows gained wide spread among nizhnynovgorod farms up to 80%, e.g. Endometritis and subinvolution of uterus 37,4 and 23,9 respectively. By clinical examination of newborn calves it was established, that in the first month of life 50,3% fall ill with gastrointestinal diseases of various etiologies. The die-off of calves reached 29%. Using "bio-tec" drug to dry cows decreased the percentage of postpartum pathology by 35% and reduced the time of involution of uterus for 11,2 days; the service period reduced by 21,2 days and the diseases of newborn calves was twice less, that increased the energy of growth and in 16 month age heifers went over animals of the control group by 10%, that allowed their earlier use for reproduction. So, the results of conducted research showed, that twice a day injection of tissue drug "bio-tec" to dry cows in 10ml dose 60-55 and 40-35 days to calving contributes reducing of obstetric pathology. Subsequent use to calves in 4ml dose in 5-8 days age increases the safety of calves and positively influences the live weight gain, that in fact gives abilities of more effective cattle breeding.

An experiment was conducted for a period of 60 days with twelve bull calves with an average live weight of 77.78 ± 10.96 kg to determine the effect of treatment of rice straw with Wood Ash Extract (WAE) on feed intake, nutritive value, growth rate and economic benefits. The experimental animals were divided into three groups A, B and C having four animals in each. They were supplied randomly with three rations following randomized complete block design. All rations were made iso-nitrogenous by using urea as a source of nitrogen. Animals of group A were fed untreated rice straw, whereas, group B and C were fed urea-treated and WAE treated rice straw, respectively. The chemical analysis showed that treatment of rice straw with WAE increased ash content of straw from 13.93% to 16.45% and decreased the NDF content from 67.39% to 63.00%. The daily DM intake per 100 kg live weight of diet B was significantly (P<0.01) higher than that of diet A and C. The daily CP intake per 100 kg body weight of diet B (553.3g) was significantly (P<0.05) higher than that of diet A (449.5g). Similarly, the organic matter (OM) intake in bull calves fed diet B was significantly (P<0.05) higher than those fed diet A and C. The average daily live weight gain with diet B and C was significantly (P<0.01) higher than diet A. The animals fed diet B and C were more efficient in converting feed into live weight than animals fed diet A. Treating rice straw with wood ash extract improved the nutritive value, it significantly (P<0.01) increased the apparent digestibility of DM, OM, CP, ADF and NDF. It also increased the DCP, DOM, DNDF and DADF contents of rice straw compared with untreated straw. Although the total feed cost of untreated group is lower than those of WAE and urea-treated groups, the feed cost per kg live weight gain as well as the feed cost per kg meat production of WAE and urea-treated groups were significantly (P<0.01) lower than that of untreated rice straw. It may be concluded that nutrient composition and digestibility of rice straw and live weight gain of animals can be improved by treating rice straw with wood ash extract.

This study was undertaken to know the effect of silage and soybean straw based Total Mixed Ration (TMR) on the growth performances of growing bull calves. 30 growing bull calves were divided into 5 treatment groups considering their initial body weight 111.30±6.67 to115.66±10.69 kg and age 24 to 26 months, respectively. Five types of TMR were prepared with different roughage and concentrate ratios (R: C) as T1=70:30, T2=60:40, T3=50:50, T4=40:60, T5=30:70. TMR intake, DM intake, CP intake of animals in T2 group was significantly (P<0.001) higher. Significantly higher (P<0.01) DM and CP digestibility were observed in T2. No significant differences observed for live weight gain. The ADG was slightly higher in T2 group (0.860 kg/day) but no significant differences were found among the treatments. Based on the results, it may be concluded that using a 60:40 (R: C) TMR can be formulated for fattening bulls for proper growth and maintenance. Bangladesh J. of Livestock Res. 21-25: 82-88, 2018

The objective of the current study was to examine the effects of mannan-oligosaccharides or inulin on HF dairy heifers’ starter feed intake and daily weight gain in farm situations. We measured these parameters across two experiments. In Trial 1 (T1), next to the control group, 15-15 HF heifers received MOS or inulin supplementation from 1st day of age to weaning. The amount of the supplementations changed according the calves’ age and the amount of milk replacer from 12 g to 24 g/calf/day. We measured the individual feed intake daily, the live weight at 0, 14, 21 and 60 days. In the second experiment (T2) we used 30 HF heifers also in three group (Control, MOS, Inulin) but we gave more from the experiment materials (28 g/calf/day MOS or Inulin). We started dosing the supplements with the colostrums feeding, and gave up on 14th day of age. We also measured the individual feed intake daily and the live body weight (BW) at 0, 14, 28, 42 and 56 days. The treatments in T1 did not cause significant differences in average feed intake, body weight and average daily weight gain. When the calves got the supplementation with colostrum too, the ADWG was significant lower in the group fed inulin than control and group fed MOS (P<0.05). We calculate the ADWG all of the experimental periods. From 0 to 14 day, and from 0 to 56 day the ADWG in inulin group was lower than control group, but the datas of group MOS did not differ from the others. Due to the distribution of the birth weights, the lower ADWG did not manifest in differences in body weight in other points of the experiments. We did not find an interaction between the treatments and the daily feed intake of calves. According with our measurements,

ABSTRACTA trial compared the voluntary water intake of 72 purchased British Friesian bull calves fed at different nutrient intake levels by varying the type and strength of the milk replacer given to 5 weeks of age. There was no control group without water on offer. Water was offered from the 1st day the animals entered the unit. All calves received 4 1/day of either cows' milk (12 calves), milk replacer with 100 g fat per kg (24 calves), milk replacer with 170 g fat per kg (24 calves) or milk replacer with 200 g fat per kg (12 calves). Standard early-weaning pellets containing 190 g crude protein per kg and hay ad libitum were on offer from the 2nd day on the unit. Results indicated that voluntary intakes of water were highest with calves fed on cows' milk and lowest on the milk replacer with 100 g fat per kg given at the lowest mixing strength, although differences were only significant in week 5 (P ≤ 0·05). By covariance analysis, the effects of water intakes on live-weight gain and on pellet intake were examined. The regression coefficient of live-weight gain (weeks 0 to 5) (kg) on water intake (weeks 1 to 5) (1) was b= 0·056 (s.e. 0·021, P ≤ 0·01). The regression coefficient of pellet intake (weeks 0 to 5) (kg) on water consumption was: b= 0·082 (s.e. 0·031, P ≤ 0·01). There was thus a significant correlation of both live-weight gain and pellet intake with water intake. For each extra litre of water consumed per day, there was an extra pellet intake of 0·082 kg and an increase in live-weight gain of 0·056 kg. There was a significant difference in total water intake according to the initial live weight of the calf.

AbstractA bull beef finishing experiment was conducted with the objective of comparing physical performance of constrasting genotypes of suckler-bred bull beef animals finished intensively on a cereal-based diet at approximately 12 to 13 months of age. Nine bulls per genotype were drawn from weaned, bull calves born to one of two dam types (Belgian Blue×Holstein/Friesian (BB) or Simmental×Holstein/Friesian (SIM)) and which had been sired by one of two contrasting sire types (Aberdeen Angus (AA) or Charolais (CH)). Bull calves were weaned at approximately 8 months of age and the finishing experiment ran from approximately 9 months of age until slaughter at 12 to 13 months of age. Cereal-based concentrate diets were offered to all bulls on an ad libitum basis throughout the experimental finishing period. Dry matter intake (DMI), live-weight gain (LWG), food conversion ratio (FCR), and carcass slaughter characteristics were quantified.Average daily LWG was 2·07, 2·11, 2·34 and 2·65 kg/day, average FCR was 5·14, 5·06, 4·70 and 4·12 kg DMI per kg LWG and average age at slaughter was 387, 381, 374 and 366 days for the AA/BB, AA/SIM, CH/BB and CH/SIM bulls respectively. These figures showed that CH sired bulls grew faster ( P<0·001), finished at an earlier age ( P<0·01) and had better food conversion ratios ( P<0·01) than AA sired bulls. CH sired bulls also produced heavier carcasses (P<0·001) with better conformation ( P<0·001) than AA sired bulls. Average cold carcass weights (CCW) at slaughter were 309, 318, 348 and 365 kg and average conformation scores (15-point scale) at slaughter were 9·28, 10·28, 12·39 and 12·75 for the AA/BB, AA/SIM, CH/BB and CH/SIM bulls respectively. Finished bulls from SIM dams had higher LWGs (P<0·01) and produced heavier carcasses (P<0·05) than bulls from BB dams. No statistically significant differences in fat score (15-point scale) were seen between any of the breed combinations with fat scores of 7·50, 7·25, 6·75 and 6·75 for the AA/BB, AA/SIM, CH/BB and CH/SIM bulls respectively. No significant differences in average daily food intake were observed between breed combinations in the experiment with average daily DMI being 10·6, 10·6, 11·0 and 10·9 kg/day for AA/BB, AA/SIM, CH/BB and CH/SIM bulls respectively.Overall, there was little evidence to suggest that the rate of bull LWG declined to bring about any meaningful reduction in productivity as average bull live weight increased from approximately 9 months of age until slaughter at 12 to 13 months of age. When finished on a nutrient-rich, cereal-based concentrate diet, excellent animal performance and commercially acceptable carcasses can be produced from the UK suckler herd using genetically superior sires of either traditional UK or continental beef cattle breeds. Results from this study indicate that CH sired bulls out-performed AA sired bulls, especially when produced from SIM cows.

The aim of this work was to analyze the growth abilities of bull and heifer calves (n = 190) of the Charolais breed calved in one herd from 2006 to 2011. The evaluation was carried out during the period of calf raising, focusing to the effects of sex, parity and the mating method on live birth weight (BLW) and the live weight at 120 (LW120), 210 (LW210) and 365 (LW365) days of life, as well as the average daily weight gain reached by the age of 120 (G120), 210 (G210), and 365 (G365) days. Statistical analysis was carried out with the use of the SAS 9.3 program. The effect of sex on the live weight and average daily weight gain was statistically significant on the level of P < 0.01 always in favour of the bull calves (BLW +3.05 kg, LW120 +29.35 kg, LW210 +36.98 kg, and LW365 +117.23 kg). The lowest live birth weight was detected in the calves of primiparous cows (BLW = 45.46 kg; P < 0.01). The higher parity, the higher live birth weight was determined, with maximum values in cows from the fourth calving. The trends were similar in live weight at 120, 210 and 365 days of age, when significance level was P < 0.05. The parity effect on the average daily weight gain (G120, G210 a G365) was statistically insignificant (P > 0.05). The effect of embryo transfer (ET) and other commonly used reproduction methods (insemination and natural mating, AI/PP) was evaluated as well as. The calves born after embryo transfer showed a significantly (P < 0.01) higher the live birth weight as well as weight at different ages (BLW +5.85 kg, LW120 +18.15 kg, LW210 +22.94 kg and LW365 +35.43 kg), and G120 only (+100 g×day−1; P < 0.05). These results pointed the suitability of using the biotechnological reproduction methods, especially in relation to the total weight of the reared and fattened animals.

Aim. To study in a comparative aspect the reproductive abilities of crossbred heifers obtained as a result of industrial interbreeding. Material and Methods. Zootechnical and mathematical methods of analysis, as well as the documents of zootechnical breeding records available on the farm, cards of breeding bulls-producers were used in the course of research. The digital material was biometrically processed on a PC using the Microsoft Office Excel program. Results. Studies have shown that crossbred young animal of all four experimental groups were characterized by high growth rates and gain in live weight. At the same time, the most weighty and forward were the three-breed hybrid Hereford heifers of the III group with the genotype ½ hereford x ¼ charolais x ¼ simmenthal. However, the rapid gain in body weight did not affect the age of the onset and end of puberty in young animals of this group and amounted to 258.30 and 316.22 days. respectively. In crossbred heifers of Kalmyk breed of group I with a genotype of ½ kalmyks. x ¼ salers x ¼ simmenthal faster than all their peers, puberty began and ended (249.30 and 301.40 days, respectively), which made it possible to start inseminating them first (485.50 days). Conclusion. In crossbred first-calf heifers of all four genotypes, good maternal qualities were noted, which allows them to be used in the formation of broodstock in beef cattle breeding. To increase the production of beef and improve its quality, it is advisable to effectively use the genetic potential of the Kalmyk and Hereford breeds.

The leading farms of the Sumy region studied the peculiarities of the growth of repair heifers of Ukrainian Black-and-White (PZ PE "Burynske") and Red-and-White (LLC "Mlynivskyi complex") dairy breeds. The absolute and relative indicators of live weight gain of heifers in the age dynamics from birth to 18 months of age were studied. Heifers of the Ukrainian Red-and-White dairy breed (36.2 kg) were the best in terms of live weight at birth in comparison with the peers of the Ukrainian Black-and-White dairy breed (33.9 kg). Their advantage persisted during the 18-month growing period. Repair heifers of the Ukrainian Red-and-White dairy breed at the final stage of development with an average live weight of 414.2 kg exceeded the peer of the Ukrainian Black-and-White dairy breed with a highly reliable difference of 15.5 kg (P <0.001). The development of repair heifers of both breeds within the obtained live weight indicators ensured their increase at the time of mating age at the level of 76-80% of the minimum target standards set for the first-born cows of dairy type of the created breeds. The average daily gains in live weight in the milk period averaged 810.4 g in heifers of the Ukrainian Black-and-White dairy breed, and 847.3 g in their peers of the Ukrainian Red-and-White dairy breed, the highest in the animals of the Ukrainian Red-and-White dairy breed herd LLC "Mlynivsky complex". The results of research showed that with the creation of appropriate conditions for feeding and keeping repair heifers of Ukrainian Black-and-White and Red-and-White dairy breeds were capable of high growth intensity.

SUMMARYThe effect of a gradual increase in dry-matter concentration from 140 g/kg (LD diets) to a maximum of 215 g/kg (HD diets), and the effect of an increase in fat concentration from 225 g/kg D.M. and reduction in protein concentration from 298 g/kg D.M. (LF diets) to 254g fat and 211g protein/kg D.M. respectively (HF diets) was examined with 32 Friesian bull calves in a 2 × 2 factorial experiment. Milk substitutes were offered ad libitum in two feeds daily from 2 days of age. The dietary changes were first introduced at 7 weeks of age and differences became progressively greater as further changes were made at 9, 11 and 13 weeks. The calves were slaughtered at 16 weeks of age.Dry-matter intake for calves given the HD diets increased faster with age after 7 weeks than that for calves given the LD diets. For the period 7–16 weeks, calves given the HD diets consumed 17% more D.M. than those given the LD diets and had a 13% greater rate of live-weight gain (1·57 v. 1·39 kg/day), although most of the increase in weight gain occurred between 9 and 13 weeks of age.There was no significant effect on D.M. intake or on live-weight gain of altering the fat and protein concentrations in the milk substitute, although feed conversion ratio (kg D.M. intake/kg weight gain) was higher for the HF than for the LF diets. Apparent digestibility of D.M., crude protein and fat were reduced with the HF diets, but the efficiency of retention of the digested nitrogen was improved. During the second and third weeks of life, D.M. intake reached a peak at approximately 67 g/kg0·75 and subsequently declined to stabilize at about 56 g/kg0·75. However, a gradual increase in concentration of the milk substitute from 140 to 215 g D.M./kg increased intake to about 62 g D.M./kg0·75. The results clearly indicate that, at a dietary concentration of 140 g D.M./kg, maximum D.M. intake cannot be achieved because the volume of fluid that needs to be ingested exceeds the capacity of the digestive system. In contrast, at reconstitution rates increasing from 140 to 215 g D.M./kg, distension of the stomach becomes less important and physiological and metabolic factors seem to assume a greater role in the control of feed intake.
