Two biological trials were conducted to determine the energy and lysine requirements of “TANUVAS Namakkal gold Japanese quail” for production performance. The economic impact of different levels energy and lysine during the chick (0-2 weeks) and grower (3-5 weeks) phases was assessed using seven hundred and twenty straight-run, day-old chicks randomly grouped in nine treatments with four replicates of twenty chicks each. Three levels of energy (2800, 2900 and 3000 kcal/kg) and three levels of lysine (1.2, 1.3 and 1.4%) were tested for chick and grower phase of the first experiment. The net profit per bird (Rs. 8.49) was high in group T1 (low energy and low lysine) and the net profit per kg live weight (Rs. 48.57) was high in T2 (2900 kcal/kg and 1.2%). For the second experiment an energy level of 2700, 2800 and 2900 kcal/kg was fixed for chick and grower mash, lysine level of 1.2, 1.3 and 1.4% was fixed for chick phase and 1.1, 1.2 and 1.3% for grower phase and the crude protein level was fixed as 20.3 and 19.4 per cent for chick and grower mash respectively for the second trial. The net profit per bird (Rs. 7.18) was high in group T6 and the net profit per kg live weight (Rs. 37.62) was high in T6 (2900 kcal/kg and 1.3% lysine during chick phase and 1.2% lysine during the grower phase).

An experiment was conducted with fifty four, 21 days old synthetic broiler (fifth generation) to study the effect of different levels of dietary protein on the performance of broiler during growing and finisher period. Three levels of protein i.e. T1 (18% CP), T2 (19% CP) and T3 (20%CP) were considered as the dietary treatments. The body weight achieved at 42 days of age was 1422.00, 1705.37 and 1563.67 gm in T1, T2 and T3, respectively which differs significantly (p< 0.01). The live weight gain at 42 days was also highest in T2 (19% CP) diet and significantly (p< 0.05) differed from T1 (18% CP) and T3 (20% CP) diets. Feed conversion ratios at the end of experimental period were 2.20, 1.75 and 1.87 in T1, T2 and T3, respectively which differs significantly (p<0.05). The performance index at 42 days of age was 50.66, 82.67 and 63.58 for T1, T2 and T3 respectively while feed consumption, livability and meat yield were not significantly (p>0.05) affected by dietary treatments. The net profit per kg live broiler was significantly highest (Tk.14.09/kg) (p<0.01) in T2 diet as compared to other treatments. It may be concluded that 19% crude protein diet, was the best with respect to growth, FCR and net profit for synthetic broiler (fifth generation) during growing and finisher period.DOI = http://dx.doi.org/10.3329/bjvm.v8i2.11193 Bangl.

SUMMARY1. All-concentrate diets given ad libitum and containing different levels of fish meal, and varying in crude protein content from 16 to 22% in dry matter were given to eight Friesian steers at 150 kg. and at 240 kg. live-weight.2. At a mean live-weight of 150 kg., the retention of nitrogen increased significantly to a maximum of 41.5 g. per day on the diet having 22% crude protein in dry matter. At 240 kg. live-weight, the maximum retention of 37 g. per day was achieved at 20% crude protein in dry matter.3. Faecal nitrogen excretion per unit of metabolic body weight was approximately constant at all protein levels and at both live-weights.4. Urinary nitrogen excretion per unit of metabolic body weight increased with increasing crude protein level in the diet and for any crude protein level was higher at 240 kg. than at 150 kg. live-weight.

Com o objetivo de avaliar o efeito de duas linhagens (italiana e japonesa) e de dois níveis de proteína bruta (20 e 26% PB) sobre o desempenho para corte foram utilizados 144 machos de codorna, criados em gaiola de 1 a 49 dias. Foram alojadas nove aves por gaiola, sorteadas de acordo com um esquema fatorial 2 x 2 em delineamento inteiramente aleatorizado com quatro repetições. O desempenho foi avaliado semanalmente. A linhagem italiana apresentou maiores peso médio, ganho de peso médio e consumo médio do que a japonesa. O consumo médio relativo e a conversão alimentar da linhagem italiana foram menores, indicando melhor capacidade de utilização do alimento. Abstract Male quails (144) were reared from 1 to 49 days in cages, to evaluate the effect of line (Italian and Japanese), and crude protein level (20 and 26% CP) upon growth performance for meat production. Nine birds were housed per cage, sorted out according to a 2 x 2 factorial scheme in an entirely randomized design with 4 repetitions. Growth performance was evaluated weekly. The Italian line had higher mean body weight, mean gain weight and mean feed intake than the Japanese line. The Italian line showed lower or equal means of feed intake adjusted for body weight, indicating that it had better feed utilization. Mean feed conversion of the italian line was better than that of the Japanese line.

Low Energy Diet

Diets for broiler chickens (n=90) were supplemented with chromium (CrCl3, 6H2O), either alone (0·2 mg/kg diet) or in a combination with ascorbic acid (0·2 mg Cr and 50 mg ascorbic acid/kg diet). The objectives of the study were to ascertain if ascorbic acid had any additive effect on the actions of chromium and whether chromium supplementation could alleviate the nutritional stress in the birds imposed by a reduced energy intake. The birds were fed at the recommended (Bureau of Indian Standards 1992) and at a lower plane of energy. Live-weight gain and diet utilization were higher (P<0·01) when the normal energy diet supplemented with chromium was fed. Food intake (35 days) was higher (P<0·001) in the birds fed with the low energy diet. There was an increase (P<0·01) in metabolizability due to the supplementation of chromium. The metabolizability of crude protein and total carbohydrate increased (P<0·05) when chromium and ascorbic acid were supplemented together. Chromium intake was higher (P<0·001) in the supplemented birds, especially in those fed with the low energy diet (P<0·05), though its retention was higher (P<0·05) when the normal energy diet was given. Chromium in combination with ascorbic acid also enhanced (P<0·01) chromium retention. Blood glucose (P<0·001) and plasma cholesterol (P<0·05) were lower in the supplemented birds and blood glucose was reduced further when ascorbic acid was supplemented together with chromium (P<0·01). Plasma protein increased (P<0·05) in the supplemented chickens. However, variation in the dietary energy concentration did not exert any significant effect on these blood parameters. Plasma chromium was higher (P<0·05) in the supplemented birds, though chromium had little effect in this regard with ascorbic acid. Plasma copper increased (P<0·05) when chromium was supplemented alone and increased further (P<0·05) when chromium and ascorbic acid were supplemented together. Deposition of chromium in the breast and thighs increased (P<0·05) due to supplementation. Protein content and total accretion of protein in the carcass were higher (P<0·05) when chromium was supplemented alone and with ascorbic acid. The supplemented birds had less (P<0·01) fat per 100 g of carcass irrespective of the dietary energy concentration. Weight of the hot carcass increased (P<0·05) due to chromium supplementation although dietary energy concentration did not affect this particular parameter. It was concluded that inorganic chromium supplementation (0·2 mg chromium/kg diet) might effectively enhance the growth performance, diet utilization and carcass characteristics in broiler chickens. Addition of ascorbic acid might also be beneficial in this regard. However, dietary energy concentration was more critical and to yield the maximum benefit of Cr supplementation in broiler chickens, an optimum level was essential.

Summary1. An experiment involving 64 individually-penned pigs (32 females (gilts) and 32 castrated males (barrows)) was conducted over the live weight range 50 to 83 kg, to study the effects of a parenterally administered anabolic steroid upon the performance and carcass measurements of gilts and barrows given either a 15·0% or an 18·8% crude protein (CP) diet at two different levels.2. The steroid significantly improved both daily weight gain (+5·2%) and food conversion ratio (+4·8%) of gilts and barrows.3. There were no significant treatment interactions for either daily weight gain or food conversion ratio, but the data suggest that gilts responded to the hormone to a greater extent than barrows at the particular dose level of the steroid administered.4. The steroid significantly improved the carcass, as assessed by linear backfat measurements, of pigs given the higher CP diet but had no effect upon carcass measurements of pigs given the lower CP diet.

Cost Of Production

The study investigated different feed restriction programs during an 8-week broiler chicken growing cycle as a management strategy for reducing cost of production. Initially, 90 Hubbard day-old chicks fed ad libitum a commercial starter feed supplying 24% crude protein and 3000 kcal of ME/kg for 4 weeks. Thereafter, they were randomly allotted to five different feed restriction programs (R0, R5, R56, R67 and R57) utilizing finisher diets supplying 19% crude protein and 2850 kcal of ME/kg from 5-8 weeks. Each program had three replicates and six birds per replicate. Unrestricted (R0) was the control where birds fed ad libitum. In R5, birds were restricted the 5th week; R56, 5th and 6th weeks; R67, 6th and 7th weeks, and R57, 5th and 7th weeks. However, all the feed-restricted birds fed ad libitum in the 8th week. Feed restriction involved feeding one-third feed intake of R0 birds starting from 14.00 to 18.00 h daily and performance parameters recorded. Feed restriction negatively affected growth performance as the severity of restriction increased. Final body weight, carcass weight, average daily gain and average daily feed intake were similar (P>0.05) for R0 and R5 but higher than R56, R67 and R57. However, feed restriction did not significantly affect (P>0.05) carcass and breast yields or feed conversion ratio except for R67, the least (P<0.05) feed efficient. Feed cost, cost of production and revenue declined as the period of restriction increased. However, profit or profit/kg live weight, economic efficiency (EE) of feed and relative EE of feed were highest for R0 followed by R5, R56, R57 and R67 in that order. Generally, birds restricted for 1 week performed better than those restricted for 2 weeks and birds restricted continuously for 2 weeks before the last week of re-alimentation and slaughter were inferior to others. These results suggest that the duration and timing of feed restriction can reduce cost in broiler meat production without seriously affecting performance or economics of production depending on the restriction program applied.

The effects of varying levels of dietary energy and protein on gross morphology and histology of testes of FUNNAB – Alpha chickens were studied at the Abubakar Tafawa Balewa University Bauchi, Bauchi state. Twelve cocks were randomly divided into four dietary treatments; Standard diet (SD) (Control) (2650Kcal/Kg ME/ 16%CP), High Energy – Low Protein (HELP, 2800 Kcal/Kg ME/ 14%CP), High Energy – High Protein (HEHP, 2800 Kcal/Kg ME/ 18% CP) and Low Energy – Low Protein (LEHP, 2400 Kcal/Kg ME/ 18%CP) groups. A total of twelve FUNAAB – Alpha cocks were used for this experiment. The cocks were reared in floor pens under natural mating. At 69 weeks of age, all the cocks were slaughtered and testicles carefully removed for gross morphology and histological studies. A significant (P<0.05) influence of diet was noted on live weight with cocks fed HELP diet being heavier (P<0.05) than those in the other treatment groups. Means for all parameters of testicles measured where not different (P>0.05) from each other. Histological sections of the testes showed that HELP diet had mild effect on spermatogenesis evidenced by the scanty spermatozoa in the tubular lumen. It was concluded that FUNAAB – alpha cocks can be fed diets meant for breeding hens without adverse effect on spermatogenesis. However, feeding the LEHP diet produced roosters that were overweighed with slightly impaired spermatogenesis.
