Present experiment was conducted to study the effect of varied levels of metabolizable energy (ME) on performance and antioxidant status of Murrah buffaloes. Advance pregnant Murrah buffaloes (n=16) were randomly divided into three experimental groups i.e., 5, 5 and 6 animals in LME, MME and HME, respectively on the basis of most probable production ability (MPPA) and lactation number. They were fed graded levels of ME, namely low metabolizable energy (LME), medium metabolizable energy (MME), high metabolizable energy (HME) which is 85, 100 and 115 percent of ICAR, 2013 requirements for 130 days, duration i.e., 40 day prepartum to 90 days postpartum. Animals in group LME, MME and HME were offered concentrate with metabolizable energy content (MJ/kg DM) 11.80, 12.18, and 13.85, respectively. Green fodder (maize) and dry roughage (wheat straw) were fed as per the experimental protocol. No significant effect on dry matter intake (DMI), crude protein (CPI) and metabolizable protein (MPI) (% BW) were observed due to dietary variation in ME. ME intake (MJ/100 kg BW) before and after calving was statistical (P>0.05) higher in HME (15.01, 24.66) followed by MME (14.07, 22.11) and LME (12.33, 19.16) groups, respectively. Significant (P>0.05) higher milk yield efficiency (kg/kg DMI) and 6% FCM (kg/kg DMI) were observed in MME in comparison to HME group. The antioxidant profile revealed no significant influence of dietary treatment on superoxide dismutase (SOD) and ferric reducing activity of plasma (FRAP) whereas significant (P>0.05) lower level of antioxidant status i.e., glutathione peroxidase (GPx) (µmol/L) in HME (1834.60) than LME (2240.23) was observed. Considering optimum production performance and similar antioxidant activity among treatment groups, it can be concluded that ICAR, 2013 recommendations are suitable for feeding transition Murrah buffaloes.

The aim of this study was to evaluate the growth of and feed utilization by Boer x Kacang crosses goats fed on total mixed ration differing in protein and energy levels. Four total mixed rations combination were formulated to contain 16 and 18% crude protein and 2650 and 2850 Kcal ME/ kg DM (dried matter) energy density. Twenty-eight male Boer x Kacang crosses goats (14.5 ± 1.14 kg) and of age ranging from 4 to 5 months were randomly allocated to one of these four TMRs (total mixed rations) (7 animals/TMR). The effects of dietary treatment were assessed using the general linear model and significance of the diet effects was detected using Duncan’s multiple range test. Dry matter intake increased as metabolizable energy density of diet increased from 2650 to 2850 Kcal/kg DM, but it is not affected by increasing crude protein level from 16 to 18%. The average daily gains were not improved (P>0.05) as the crude protein levels and metabolizable energy density of diet increased. Crude protein levels and ME density did not affect (P>0.05) the DM, OM and energy digestibility, but NDF digestibility was affected by the ME density of diets (P<0.05). Daily N intakes were greater (P<0.0%) in goats received diets higher in the crude protein and metabolizable energy levels. At this high rate of feed intake this type of goats are able to gain optimally when offered feed with crude protein level of 16% and metabolizable energy density of 2850 Kcal/kg DM.

Objective: The objective of this study was to determine the digestible energy (DE) and metabolizable energy (ME) of yellow dent corn sourced from different meteorological origins fed to growing pigs and develop equations to predict the DE and ME of yellow dent corn from southwestern China.Methods: Sixty crossbred barrows were allotted to 20 treatments in a triplicate 20×2 incomplete Latin square design with 3 replicated pigs per dietary treatment during 2 consecutive periods. Each period lasted for 12 days, and total feces and urine during the last 5 days of each period were collected to calculate the energy contents.Results: On dry matter (DM) basis, the DE and ME in 20 corn grain samples ranged from 15.38 to 16.78 MJ/kg and from 14.93 to 16.16 MJ/kg, respectively. Selected best-fit prediction equations for DE and ME (MJ/kg DM basis) for yellow dent corn (n = 16) sourced from southwestern China were as follows: DE = 28.58–(0.12×% hemicellulose)+(0.35×% ether extract)–(0.83×MJ/kg gross energy)+(0.20×% crude protein)+(0.49×% ash); ME = 30.42– (0.11×% hemicellulose)+(0.31×% ether extract)–(0.81×MJ/kg gross energy).Conclusion: Our results indicated that the chemical compositions, but not the meteorological conditions or physical characteristics could explain the variation of energy contents in yellow dent corn sourced from southwestern China fed to growing pigs.

Abstract The objective of this study was to evaluate the performance, under confinement conditions, of lambs born from ewes fed different energy levels during the final gestation and lactation period. Seventy-one ewes were distributed in two treatments according to the metabolizable energy (ME) levels in the diet: CTL = according to the NRC (2007) recommendations for each stage (gestation and lactation); PLUS = CTL plus 10% of energy per kilogram of dry matter. The total ME intake for the CTL group was 4 and 4.2 Mcal/day during the end of gestation and lactation, respectively, and for the Plus group, the ME intake were 4.8 and 5 Mcal/day. Thirty-five intact male lambs were weaned at 60 days and confined for an additional 60 days. In confinement, lambs were fed ad libitum with the same experimental diet their ewes received. The experimental design was analyzed as randomized complete blocks. The metabolic weight (BW0.75) at the confinement was influenced by maternal nutrition. Lambs of ewes fed with lower energy content were lighter compared to the PLUS group. At the beginning and the end of the confinement, the BW0.75 of the CTL was 8.80 and 15 kg0.75, and the PLUS was 11.4 and 17.6 kg0.75, respectively (P < 0.0001). The maternal diet containing higher energy content resulted in heavier carcass for commercialization. The values of weight gain and feed conversion were not influenced by maternal nutrition (P > 0.005), with mean values of 350 and 4.72 g/d, respectively. We concluded that lambs from ewes fed with greater energy intake had heavier body weights at the beginning and at the end of the confinement, possibly increasing the sustainability of the meat lamb production systems.

1. Twelve crossbred does (New Zealand White × California) were offered a diet of high protein and metabolizable energy content (249 g/kg dry matter (DM) and 13·6 MJ/kg DM respectively) throughout a 32 d lactation at one of four feeding levels (240, 280, 320 or 360 g/d). Each feeding level was replicated three times.2. Milk output was measured by weighing the does before and after their one daily suckling period.3. The lactation was divided into four consecutive 8-d periods. Each doe was placed in a direct calorimeter for 48 h around the mid-point of each of these periods and measurements of energy exchange were made. Nitrogen balance was also measured throughout the study period.4. Milk samples were taken from a parallel group of animals and the estimates of milk composition were applied to the main group of does.5. From the second period of lactation onwards nearly all does mobilized body tissue to support milk energy secretion, although there was no loss of weight. Multiple regression analyses were used to examine the apparent efficiency with which metabolizable energy and body-tissue energy were utilized for milk production. Overall, the relationship was described by the equation:Period of lactation … 2 3 4Milk E = 0.735 me intake – 0·938Body ER –296 –280 –276(se 0-020) (se 0-039)where Milk E is the milk energy output, ME intake is the metabolizable energy intake and Body ER is the body energy retention, all expressed in kJ/kg body-weight0·75 per d.All does appeared to be in positive N balance throughout lactation on this high-protein diet.

AbstractOn the basis of their respective metabolizable energy contents, supplemental marine oil was partially replaced with a maize starch/dextrin mixture in diets containing approximately 500 g crude protein per kg food thus lowering the total dietary lipid concentration from 141·6 to 100·9 g/kg. The basal diets were then supplemented with thiamin hydrochloride at 0·5, 5·0 and 10·0 mg/kg food to produce six test diets in all. After 182 days of feeding, the fish given the diets containing the higher lipid content with a thiamin supplement of 10·0 mg/kg had shown significantly better growth and food utilization (food conversion efficiency and apparent net protein utilization) than the fish presented with the remaining five diets. Thiamin supplements of 5 mg/kg or less resulted in poorer performance amongst the fish given the high lipid diets. The fish given all three of the low oil diets performed poorly by comparison with those given the high lipid, high thiamin diet and performance was comparable with that of the fish given the high lipid diets containing thiamin at 5 mg/kg or less. Proximate carcass composition in terms of moisture, protein and lipid was unaffected in response to diet. Glycogen accumulation in the liver was significantly elevated amongst the fish given the low lipid diet where the thiamin supplement was 5·0 mg/kg or more. The haematology of the fish was not significantly altered in response to diet although elevated haematocrit was associated with decreasing thiamin supplementation. It would appear that for the seabream, lipid and carbohydrate are not exchangeable on the basis of their metabolizable energy content. When given high lipid diets the thiamin requirement of the seabream is in excess of 5·0 mg/kg and increasing the thiamin supplement to 10 mg/kg in high carbohydrate diets made no impact on performance.

ABSTRACTFour groups of six cows were fed from 12 weeks before calving to achieve condition scores at calving of 3·15 (F) and 2·15 (T). For the first 20 weeks of lactation all cows were given 8 kg concentrate (13·93 MJ metabolizable energy (ME) per kg dry matter (DM), 200 g crude protein (CP) per kg DM) which contained either a high or a low dietary concentration of undegradable dietary protein (UDP) (70 g/kg DM, H, and 49 g/kg DM, L) and 3 kg sugar-beet pulp. Hay was also offered ad libitum.There was no significant effect of treatment on milk yields over the first 20 weeks of lactation (overall mean yield 27·3 (s.e. 3·65) kg/day) but cows in group FL tended to produce less (P > 005). Milk composition was similar for all groups (48·8 (s.e. 5·12) g fat per kg, 27·2 (s.e. 1·48) g protein per kg and 49·0 (s.e. 2·52) g lactose per kg). DM intakes for groups FH, FL, TH and TL were 18·1, 16·9, 17·5 and 18·2 (s.e.d. 0·58) kg/day, respectively (TL v. FL, P < 0·05; FH v. FL, P < 0·05). Mean condition scores for groups FH, FL, TH and TL respectively, were 3·T7, 3·13, 2·21 and 2·08 (s.e.d. 0·18) at calving; 2·25, 2·50, 2·21 and 1·83 (s.e.d. 0·27) in week 10; and 2·46, 2·83, 2·46 and 1·96 (s.e.d. 0·35) in week 20, of lactation. Groups FH, FL, TH and TL lost proportionately 0·09, 0·02, 0·01 and 0·04 (s.e.d. 0·035) of their calving live weights, respectively, over 20 weeks of lactation.It is concluded that increasing the supply of UDP to cows which are fat at calving results in a greater negative energy balance and a small though non-significant increase in mobilization of body fat reserves. At the dietary ME and protein concentrations used, the thin cows could not respond to increased UDP supply and their intake was limited by physical restriction.

The objective of study was to evaluate the effects of energy level in starter ration on blood biochemical parameters, hormone profile, immune response and antioxidant status of calves. A total of eighteen angus calves were divided into three groups in such a way that each group had six calves. Three energy levels were {9 MJ/kg, low metabolizable energy (LME), 12.38 MJ/kg, medium metabolizable energy (MME) and 13.62 MJ/kg, high metabolizable energy (HME)}fed to experimental groups. Results showed that hemoglobin, red blood cells, hematocrit, thrombocytocrit and high-density lipoprotein was higher in HME diet (plessthan0.05). While, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean platelet volume and platelet distribution width was higher in MME diet as compared to HME diet plesstha0.05). Results of immunity revealed that IgA content were lowest in calves fed LME diet plesstha0.05). Calves received different energy level in the diet had no effect on IgG, IgM and C4 (P>0.05). However, the calves on LME starter diet represented higher blood complement C3 contents plesstha0.05). It is concluded that blood metabolites were influenced by energy level in Angus calves.

A practical type basal poult starter was supplemented with 17.6 p.p.m. procaine penicillin, and 4 p.p.m. oleandomycin to provide three experimental diets. These were fed to turkey poults from day-old to 38 days of age. Each of the antibiotic-supplemented diets resulted in a significant increase in body weight at 13, 27, and 38 days of age when compared with the unsupplemented basal diet. Metabolizable energy values of the supplemented diets did not differ significantly from that of the control ration. These results confirm previous reports that the stimulation of growth rate of turkey poults as a result of dietary treatment, and in particular antibiotic supplementation, is not necessarily associated with an increase in metabolizable energy values of the diets.

AbstractAbstract The study evaluates the effects of two dietary Ca: P ratios (1·5: 1v. 2·5: 1) and metabolizable energy (ME) contents (17·3 MJ/kg dry matter (DM)v. 19·2 MJ/kg DM) on the development of osteochondrosis, foot bending and performance in juvenile male blue foxes (Alopex lagopus). Four experimental groups (no. = 10 per group) were formed : (1) low energy, lagopus). low Ca: P (LELC); (2) normal energy, low Ca: P (NELC); (3) low energy, normal Ca: P (LENC); and (4) normal energy, normal Ca: P (NENC). The experiment started at weaning in mid July and finished in early October. From mid August onwards, animals on the normal energy diets (NELC, NENC) grew significantly faster (P< 0·001) than animals on the low energy diets (LELC, LENC). The final body weights of the normal energy groups were 1·5 kg higher than those of the low energy groups (P< 0·001). The dietary Ca: P ratio did not affect live-weight gain. Foot bending increased significantly from summer to autumn (P< 0·001). Changes in foot bending between initial and final evaluations showed that bending was significantly greater (P< 0·05) in animals on normal energy (NELC, NENC) than on low energy diets (LELC, LENC). Significant differences were not found in the mean degree of damage in foot and cartilage between the groups. Ulna breaking strength was significantly higher (P< 0·05) in normal energy (NELC, NENC) than in low energy (LELC, LENC) animals. Ulna calcium and phosphorus concentrations of the normal Ca: P (LENC, NENC) groups were significantly higher (P< 0·001,P< 0·05) than those of the lower Ca: P (LELC, NELC) groups. The bone (ulna) calcium and phosphorus concentrations tended to be higher in the normal energy (NELC, NENC) than in the low energy (LELC, LENC) groups (calciumP= 0·07; phosphorusP= 0·06). The bone Ca: P ratio was higher (P< 0·001) in the normal (LENC, NENC) than in the low Ca: P diet (LELC, NELC) animals. The carcass weights of normal energy animals (NELC, NENC) were significantly higher (P< 0·001) than those of low energy (LELC, LENC) animals. The fat : dry matter ratio was higher (P< 0·05) in normal (NELC, NENC) than in low energy (LELC, LENC) carcasses. We conclude that the Ca: P ratio of the diet has no effect on the development of osteochondrosis or bending of the foot. The higher body weight caused by normal as opposed to low metabolizable energy content seems, however, to increase the incidence of foot bending.
