Objective: To evaluate the use of nurse sows and post-weaning nutrition strategies for low wean weight (WW) pigs on lifetime growth and efficiency.Methods: Animals (n = 270) were assigned to one of five treatments at 28 d. Low WW pigs (<6 kg) were either weaned and offered a special dietary regime recommended for low WW pigs (WEAN) or placed on a nurse sow (NURSE) and weaned at 49 d. Normal WW pigs (9 kg) (NORM) were also weaned at 28 d. After weaning, NORM and NURSE pigs were offered either a ‘high’ (4 kg/pig of starter 1 diet followed by 8 kg/pig of starter 2 diet) or ‘low’ (8 kg/pig of starter 2 diet) starter diet allowance in a 2×2 factorial arrangement. A typical grower diet was then offered, followed by a typical finisher diet until 147 d of age.Results: NORM pigs where heavier throughout their life compared to NURSE pigs (91.4 kg vs 76.2 kg at 147 d; p<0.001). WEAN pigs were heavier at 70 d compared to NURSE pigs (23.9 kg vs 21.0 kg; p<0.001), but there was no significant difference at 147 d between NURSE and WEAN treatments. NURSE pigs had reduced feed intake throughout the finishing period (1.6 kg/d; p<0.001) compared to WEAN (2.0 kg/d) and NORM (1.9 kg/d) pigs. Feed conversion ratio (FCR) of NURSE (2.20) was lower than NORM and WEAN during the finishing period (2.40 and 2.79, respectively).Conclusion: Extended (up to 49 d) nursing for low WW pigs resulted in improved FCR during the finishing period, but no overall improvement in growth rate compared to low WW pigs weaned at 28 d and offered a specialised starter regime. Normal WW pigs where significantly heavier than low WW pigs throughout the study.

An experiment was designed and carried out to assess the survival, growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Heterobranchus bidorsalis fingerlings fed graded levels of toasted Lima beans seed (Phaseolus lunatus) meal based diets with the aim of establishing the best inclusion level of Lima beans seed meal. One hundred (100) fingerlings with an initial mean weight of 2.5± 0.5g were allotted at random to five treatments in triplicate groups with each treatment tank having five fingerlings and were fed with the compounded diets. The toasted Lima beans seed meal was used to replace soybean meal in the diets in the following proportions: Diet I (0%), diet II (25%), diet III (50%), diet IV (75%) and diet V (100%). At the end of the feeding trials that lasted for 70 days, At the end of the experiment, the Specific growth rate showed no significant difference (P >0.05) among all treatments. Treatment III (3.250) had the highest specific growth rate and Treatment II (2.083) had the lowest value. Relative weight gain was highest in treatment V (20.53) with 100% lima beans and lowest in treatment II (16.95) with 25% lima beans diet inclusion level. Treatment I and IV had no significant difference (P >0.05) but these treatments had a significant difference (P<0.05) with treatments II, III and V also treatment II, III, and V are significantly different (P<0.05) from each other. There was no significant different (p>0.05) in the feed conversion ratio of treatment II, III, IV. There was also no significant difference (p> 0.05) in the feed conversion ratio of treatment I and V. Treatment II, III and IV showed a significant difference (P< 0.05) in the feed conversion ratio with treatment I and V. FCR was highest in treatment II (1.383) and lowest in treatment IV (1.162). Treatment V had the highest feed intake with value 3.775. Treatment I, II, III, IV and V had no significant difference (P> 0.05). Treatment I had the lowest feed intake with value (3.246). Protein efficiency ratio showed no significant differences among all treatment. PER was highest in treatment V (6.346) and lowest in treatment III (5.346). The survival rate was slightly different but not as a result of the feed consumed. Based on the findings in this study, it is therefore recommended that 75% inclusion level of Lima beans meal should be adopted in the formulation of feed for Heterobranchus bidorsalis.

Eighty black Nera cockerel chicks were randomly alloted to four dietarey treatmants containing 0, 10, 20 and 30% kolanut husk meal (KHM) for twelve weeks. Significant differences (P<0.05) in feed intake, weight gain and feed conversion ratio were observed. Dietary inclusion of KHM depressed (P<0.05) growth rate feed conversion ratio and nutrition uilization of cockerels birds. There were linear reduction (P>0.05) in nitrogen retention and apparent crude fibre digestibility (ACFD) of  cockerels birds at each incremental KHM dietary levels. This indicated that KHM could be effeciently utilized by cockerels up to 205 dietary level above which the depression in growth rate occurs.

An experiment was designed and carried out to assess the growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Clarias gariepinus fingerlings fed graded levels of toasted Leucaena leucocephala seed meal based diets with the aim of establishing the best inclusion level of Leucaena seed meal. One hundred and eight (108) fingerlings with an initial mean weight of 2.10g were allotted at random to six treatments in triplicate groups with each treatment tank having six fingerlings and were fed with isocaloric and isonitrogenous diets containing 40% crude protein (CP). The toasted seed meal was used to replace soybean meal in the diets in the following proportions: diets I (0%), diets II (10%), diets III (20%), diets IV (30%), diets V (40%) and diets VI (50%). At the end of the feeding trials that lasted for 6 weeks, the mean weight gains of fish, relative weight gain, specific growth rate, feed intake, feed conversion ratio and protein efficiency was highest in treatment I while mean weight gain of fish, relative weight gain, specific growth rate and feed conversion ratio was lowest in treatment V. Feed intake was lowest in treatment VI and protein efficiency was lowest in treatment II. Survival among treatments slightly varied significantly but was not as a result of the feed consumed. At the end of the experiment, the recommended inclusion level of Leucaena seed meal was 20%.

Consequences of low (mean 28.0 kg, n = 77) and high (mean 38.4 kg, n = 77) birthweight followed by slow (mean 548 g/day, n = 75) or rapid (mean 859 g/day, n = 79) growth to weaning for feedlot growth, intake and efficiency from 26 to 30 months of age were determined in Wagyu × Hereford (n = 81) and Piedmontese × Hereford (n = 73) cattle. Cattle were selected for study based on birthweight and preweaning growth rate, from multi-modal distributions achieved by imposition of low or high maternal nutrition during pregnancy and lactation, with the objective of achieving as close as possible to a 30% difference in birthweight and a 2-fold difference in preweaning growth rate between progeny groups. High birthweight cattle entered the intake test 57 kg heavier, grew 100 g/day more rapidly, and ate 1.0 kg dry matter /day more than the low birthweight cattle. The high birthweight cattle tended to have a higher feed conversion ratio than low birthweight cattle, but net feed intake did not differ due to birthweight group. Cattle grown rapidly to weaning entered the intake test 29 kg heavier, grew at an equivalent rate, and ate 0.7 kg dry matter/day more than the cattle grown slowly to weaning. No differences in feed conversion ratio or net feed intake were observed between the preweaning groups. When assessed at the same liveweight, differences in dry matter intake and/or feed conversion ratio due to birthweight or preweaning growth were no longer apparent. Interactions between prenatal and preweaning growth, or between sire genotype and early-life growth, were not evident for feedlot growth, intake or efficiency. It is concluded that severely restricted growth during prenatal life or from birth to weaning results in cattle that are smaller and consume less feed at the same age as their well grown counterparts; however, long-term effects of growth during early life on efficiency of utilisation of feed are not evident.

A trial was carried out to evaluate the effect of replacing wheat offal with rumen content on the growth performance of broiler chickens. A total of one hundred and fifty (150), one day-old broiler chicks were randomly allotted to five (5) dietary treatments containing 0, 5, 10% inclusion levels of sundried rumen content and 5 and 10% inclusion levels of roasted rumen content as a replacement to wheat offal. Each treatment was replicated three times with five (5) birds per replicate in a completely randomized design experiment. The trial lasted for eight (8) weeks. The results showed that there were no significant differences in the final weights, daily feed intake, daily weight gain and feed conversion ratio at the starter phase and finisher phases. Furthermore, no significant differences in the final weight (1346.60-1508.50g), daily feed intake (83.57-100.00g), and daily weight gain (36.43-39.53g), and were observed for the overall performance. However, there was a significant difference (P<0.05) in the feed conversion ratio with the highest being 2.69g and the lowest 2.33g in the overall performance. From these findings, it could be concluded that rumen content could replace wheat offal without any detrimental effect on the performance of broiler chickens.

Biting Behaviour

Salt (NaCl) is an essential mineral and its rate of inclusion in diets has been implicated in the development and expression of biting behaviour. Falkowskiet al., (1998) found that withholding salt from diets reduced the feed intake and feed conversion ratio of weaned pigs and significantly decreased growth rate. Studies reported by Fraser (1987), suggested that heightened appetite for salt could make pigs particularly attracted to pen mates with injured tails. More recently Tsourgiannis,et al., (2002) reported that 1.5% salt inclusion levels can significantly reduce the incidence of tail-biting, providing that there is unrestricted access to fresh water. This study investigated the effect on growth performance of pigs fed liquid diets containing high and low dietary salt levels for growing/finishing pigs.

Rice is a major staple food in Vietnam in which brown rice has been recognized as a potential feedstuff for poultry but data on nutritional value of this feed are lacking. In this study the using of brown rice as replacement of corn in chicken diet was evaluated. The body weight, feed intake and feed conversion ratio were recorded. In total, 192 day old chicks of country breed (Ri lai) were used in this study. Chickens were divided into four groups and reared at same conditions for 12 weeks. The first group as the control group fed on 100% corn, second group fed on 75% corn and 25% brown rice, third group fed on 50% corn and 50% brown rice and the last group fed on 25% corn and 75% brown rice. The average body weight of chickens among all the treatments was 1.7 kg per bird which was not significantly different (P=0.44). The total feed intake of chickens (4-5 kg) was recorded without significant difference (P=0.23), however the feed conversion ratio were significantly different (P<0.05) between treatments. This study considered as the first report that demonstrates the usefulness of brown rice as a potential alternative of corn for chicken diet in rural areas in Vietnam, especially on the prevailing conditions such as during high price spell of corn.Res.

A major cost of producing rabbits is that of feed. Palm kernel cake is cheaper and locally available than wheat offal. This study was therefore, conducted to evaluate the performance of rabbits fed Palm Kernel Cake (PKC) as a replacement for Wheat Offal (WO). Twenty weaned rabbits of both sexes were used in the experiment. The rabbits were allocated to five diets, each with four replicates. Each diet contained the same quantities of ingredients but PKC and WO were varied such that diet (A) was 0% PKC and 40% WO, (B)10% PKC and 30% WO, (C)20% PKC and 20% WO, (D)30% PKC and 10% WO, and (E)40% PKC and 0% WO to measure feed intake, growth rate and feed conversion ratio. Carcass and organs of the rabbits were analysed. Average daily feed intake of rabbits recorded for diet A, B, C, D and E was 49.37, 40.05, 38.18, 39.10 and 56.05. The results revealed an  insignificant difference in final weights of rabbits among all treatments which ranged from 777.50g (A) to 965.00g (E). The feed conversion ratio (FCR) was also not significant and ranged from 5.21 – 4.55 with diet A having the highest FCR. There were also no significant differences in carcass and organ weights among the treatments. The carcass weight ranged from 395.00g to 594.25g on diet A and E respectively. Diet E had the highest dressing percentage (57.70%) while the least was recorded for diet B (53.28%). It can be concluded that PKC compared favourably with WO and could be used to replace the latter without  deleterious effects.
