Hereford steers of a mean body weight of 227 � 3 kg were either fed in yards on a ration of 90 per cent sorghum grain, 10 per cent sorghum stubble, or were fed sorghum grain ad lib. while grazing sorghum stubble. The mean rate of daily body weight gain of steers fed in yards was 1.30 kg which was significantly greater than that of the grazing steers, 1.0 kg. The efficiency of conversion of sorghum grain to body weight and carcase weight gain was similar for both methods of feeding, but this value may have been influenced by the unknown quantity of stubble consumed by the grazing group. Grazing steers had significantly greater concentrations of vitamin A in their livers at slaughter than yard fed steers.

The effects of type of grain (wheat, barley, or sorghum), level of roughage (0, 1, and 2 kg of oaten chaff/head/day) and sodium chloride free choice on the performance of steers of a mean (� S.E.) body weight of 241 � 2 kg fed in yards for a mean period of 133 � 4 days were examined in a factorial experiment. The type of grain, the level of chaff offered to the steers, or the provision of sodium chloride had no significant effect on daily body weight gain (1.08 � 0.03 kg) or efficiency of conversion of feed dry matter (D.M.) to body weight or carcase weight gain (6.5 and 9.7 kg feed D.M./kg gain respectively). Steers fed wheat had a significantly (P<0.01) lower daily D.M. intake than those fed either barley or sorghum grain. The incidence of persistent laminitis, the death of a steer fed barley and the greater number of steers fed wheat not attaining slaughter weight of 385 kg by 180 days indicated that sorghum was probably a 'safer' grain to feed in high-grain rations than either wheat or barley. The level of oaten chaff offered to the steers did not appear to affect the incidence of digestive disturbances. Carcase weight gain represented a mean of 66.8 � 0.7 per cent of the body weight gain during finishing.

A 2 x 2 x 3 x 3 split plot design was used to investigate the effects of the following treatments on the finishing of steers : cobalt supplementation-as an intraruminal cobalt oxide pellet; vitamin A supplementation-as an intramuscular injection of 2.5 x l06 i.u. ; additives to the grain-nil, 1 per cent urea, and 1 per cent urea plus 1 per cent sodium chloride ; roughage source-wheaten chaff, sorghum silage, and lucerne chaff. Ten groups each of 10 steers, of a mean (� S.E.) shrunk body-weight of 537�3.4 lb were used. One group was slaughtered before feeding the rations to measure initial carcase weight and composition. Individual steers from the other nine groups were slaughtered at 900 lb body-weight. The mean body weight gain of all steers was 2.64 � 0.05 lb per head per day, for a mean D.M, intake of 15.7 lb grain and 2.5 lb roughage over 135 � 2.2 days. Roughage sources, sodium chloride, cobalt, and the vitamin A supplement had no significant effect on performance. Steers fed lucerne, particularly with urea, exhibited mild to moderate bloating. Carcase weight gain was significantly increased by the addition of urea to the grain. Carcase weight increased from 276 � 2.2 lb in the pre-treatment group to 482 � 1.8 lb in the finished steers. The composition of this increase was 71 per cent commercial cuts of meat, 20 per cent fat trimmings and 9 per cent bone. The mean total hepatic vitamin A reserves of the unsupplemented steers at slaughter was 38 per cent of the initial reserves ; the hepatic level in 20 of these animals was less than 10 �g/g.

SUMMARYThe intensive finishing of steers on simple rations of 10% sorghum stubble and 90% sorghum grain plus urea was investigated. Fine grinding of the grain resulted in a lower mean daily intake, but a significantly greater efficiency of conversion of feed to carcass weight gain (P < 0·01) than coarse grinding the grain. Coarse chaffing of the stubble significantly reduced the intake of the stubble in comparison with hammer milling, but had no significant effect on rate of body weight gain, total feed intake or efficiency of feed conversion.The addition to the ration of either 1 mg of selenium, or 200 mg vitamin E, 200 mg vitamin E and 100 mg vitamin K per day had no significant effect on rate or efficiency of body or carcass weight gain. Seven out of 32 steers which were not injected with 3 million i.u. of vitamin A at the start of the experiment exhibited nyctalopia. None of the 32 steers which received the vitamin A injection had hepatic vitamin A concentrations less than 33 μg/g. Vitamin A injection did not have a significant effect on the rate of body weight gain (mean ±S.E. 1·3 ± 0·03 kg per day), efficiency of feed conversion (10·4 ± 0·16 kg D.M. per kg carcass weight gain), or time to attain slaughter weight (133 ± 3 days). Drenching twice with thiabendazole had no significant effect on rate of body weight gain.

The effects of diets containing 0, 150 and 300g/kg sun-dried cassava leaf meal (CLM) on the growth performance of cockerel chicks were studied. The experimental diets A, B and C were both isonitrogenous and isoenergetic in formulation. Chicks on diets A, B and C consumed 89.89, 103.16 and 104.71g/bird/day, respectively. The mean daily body weight gain showed a significant difference (P <0.05) between treatments A and C but not between B and C (P >0.05). The highest mean daily body weight gain (20.11g/bird) was obtained on diet A, while the lowest value (11.70g/bird) was obtained on diet C. The chicks on diets B and C showed a continous depression in growth rate with increasing dietary CLM. The feed conversion ratio showed significant differences (P<0.05) between treatments. A value of 0.22 was obtained on diet A, while 0.11 was recorded on diet C. The chicks on treatment A tended to rest more often than those on treatment B or C, which appeared more "active" and "visited" the feed troughs more often.

The objective of the study was to evaluate feeding effect of microparticle protein derived from soybean meal and fish meal combined with Lactobacillus sp. at 1.2 mL on physiological condition of digestive tract and productivity of broiler. Total of 192 broiler, with initial body weight was 481.0 ± 67.2 g, given dietary treatment starting on day 21 until day 42. The experiment was assigned in a completely randomized design with 8 treatments and 4 replications. Dietary treatment were 21% intact protein (T0), 18% intact protein (T1), 21% microparticle protein (T2), 18% microparticle protein (T3), T0+Lactobacillus sp.1.2 mL (T4), T1+Lactobacillus sp.1.2 mL (T5), T2+Lactobacillus sp.1.2 mL (T6), T3+Lactobacillus sp.1.2 mL (T7). Parameters measured were total ileal lactic acid bacteria (LAB), Coliform and pH, rate of passage, daily body weight gain (DWG) and also carcass weight. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05). Experimental results showed that microparticle protein diet added with Lactobacillus sp. (P<0.05) increased total LAB and DWG, but decreased Coliform population, and slowed down the rate of passage. However, carcass weight was not significantly affected by treatments. Feeding microparticle protein (18%) with addition of Lactobacillus sp. (1.2 mL) can improve to be better condition of digestive tract based on higher LAB and lower Coliform populations, and increase daily body weight gain with the same carcass weight.

Twelve microsatellite markers on chromosome 6 were analyzed in German Holstein population to detect and locate QTL affecting daily body weight gain (DBWG). The results indicate promising location for QTL controlling daily body weight gain trait on chromosome 6. Where, three markers BMS2508 BM3026 and TGLA37 at three different positions in a distance 15.2 cM on BTA6 were associated with significant effects for daily body weight gain trait (DBWG). Comparison between this finding and previously identified QTL support the location of a QTL for growth traits on chromosome 6, where a significant QTL for birth and yearling weight was previously identified on chromosome 6 tightly close to marker BM3026. Finding from this study could be used in subsequent fine-mapping work and applied to marker-assisted selection (MAS) of production traits.

The purpose of this study was to evaluate the growth performance of cross-breeding of Belgian Blue (BB) and Ongole Grade (PO) cattle in the first generation (F1). Crossbred of BB and PO cattle used as many as 15 individuals consisting of 6 males and 9 females, also, 8 individual PO females are used which are kept in the Livestock Embryo Center (BET) Cipelang, Bogor. The observed variables were birth weight (BW), weaning weight (WW) 205 days, 1-year weight (YW) 365 days, daily body weight gain from birth (GBW) to weaning (GWW) and daily body weight gain from weaning (GWW) until the age of 1 year (GYW). Data were analyzed descriptively and the difference between cross-breeding (BB-PO) cattle and PO cattle was analyzed by t-test. The results of body weight and growth analysis showed that crossbred BB and PO cattle were higher than PO cattle at WW 205 days (165.2 ± 21.3 kg and 115 ± 15.2 kg), YW (365 days) (240.7 ± 28.1 kg and 194.9 ± 26.1 kg ) and GBW to GWW (0.675 ± 0.097 kg and 0.441 ± 0.059 kg). BW and GWW to GYW do not differ between crossbred BB-PO and PO cattle. The results of this study indicate that the cross-breeding program for BB cattle with PO cattle breeds can improve the performance of body weight and growth.

The Mean

A 60 days indoor growth trial was conducted to study the effect of dietary supplementation of biofloc meal on growth and survival of juvenile GIFT tilapia. Four isonitrogenous and isoenergetic experimental diets (32% crude protein) were prepared using biofloc meal at different inclusion levels viz., 0 (T0), 20 (T1), 30 (T2) and 40% (T3). A commercial diet (T4) was used for comparison. The feeding trial was conducted in 15 nos. of 40 l plastic troughs in triplicate, utilising GIFT tilapias weighing an average of 2 g. During the experimental period, water quality parameters were measured and recorded daily. The mean value of water temperature, pH, dissolved oxygen, salinity, ammonia-N, nitrite-N, nitrate-N, hardness and alkalinity recorded in the experimental systems were 28.5°C, 8.1, 5.5 ppm, 4.5 ppt, 0.03 ppm, 0.07 ppm, 11 ppm, 630 ppm and 162.5 ppm respectively. Among the biofloc meal enriched diets, diet T1 with 20% biofloc yielded the best results in terms of average body weight gain, feed conversion ratio (FCR), specific growth rate (SGR), protein efficiency ratio (PER) and feed efficiency ratio (FER). The mean body weight gain recorded in T1 was 25.28±0.81 g. The results demonstrated that biofloc meal is a potential ingredient that can be incorporated in GIFT tilapia diet at 20% level for better growth performance.

A longitudinal study was carried out to investigate the influence of two different rearing systems of young kids on their development to sexual maturity. Kids born to small ruminant lentiviruses-infected (SRLV) female goats were split into two groups: the immediately-after-birth weaned group and the unweaned group. Kids’ body weight (BWT) was measured before the first consumption of colostrum, and then at the age of one week, and one, two, four, and seven months. The relationship between the rearing system and BWT at each age was investigated using mixed linear models adjusted for potential confounders. The mean BWT of kids of the immediately-after-birth weaned group was significantly lower at the age of one week, one month, and two months, and then the difference became insignificant. The mean daily body weight gain (DWG) was significantly lower in the immediately-after-birth weaned group during the whole first month of life, but then DWG in both groups became equal. Crude mortality rate did not differ significantly between groups. This study shows that weaning kids immediately after birth does not appear to have any negative impact on kids’ development except transient growth retardation, which is fully compensated until they reach sexual maturity.
