Rice whole stillage (RWS) is disposed to aerobic spoilage when stored for a prolonged period. The objectives of the present study were to evaluate the fermentation characteristics of ensiled RWS with wheat straw (WS) and wheat bran (WB) inoculated with Amylomyces rouxii, as well as to evaluate their impact on the metabolic profiles and the growth performance in Japanese black steers. Ensiled blends containing RWS, WS and WB were prepared either with A. rouxii inoculation (AS) or without (US). Fifteen silo bags were made for each blend; each bag had a width × height of 110 × 110 cm. The silos were analysed on Days 0, 7, 14, 28, 42 and 60 after ensiling. Notably, crude protein concentrations were found to be higher in the US treatment than in the AS treatment. In contrast, ash and acetic acid concentrations were elevated in the AS treatment compared with the US treatment. Lactic acid (LA) concentrations did not differ between the two treatments. Furthermore, the feeding efficacies of the prepared silages were evaluated as a feeding material for Japanese black steers. Control diets were composed of total mixed ration (TMR) and timothy hay, and the test diets were composed of TMR supplemented with either 1 kg/head.day US silage blend (USTMR) or 1 kg/head.day AS silage blend (ASTMR). Steers fed on the ASTMR diet exhibited a decrease in blood LA concentrations compared with the other groups. Moreover, growth performance revealed that daily gain and final bodyweight values were similar among treatments. Collectively, RWS can be effectively ensiled with or without A. rouxii and used as a feedstuff for maintaining an adequate growth rate of steers.

Digestibility and N-retention were determined with eight barrows fed rye and barley in a crossover experiment. Dry matter and crude protein digestibility coefficients for rye were higher than those for barley, but differences in N-retention were negligible. The coefficients obtained by indirect measurement were higher than those determined directly. Seventy-two pigs were used in a factorial experiment to determine the effect on production of feeding two grades of rye at 0, 30 and 60% of pelleted and non-pelleted finisher rations. Weight gains by barrows compared with gilts were affected less by the addition of rye to the rations. The growth rate of gilts was reduced by the inclusion of 30% rye in non-pelleted but not in pelleted rations. The use of No. 2 grade rye appeared to have restricted rate of gain less than did No. 3 grade rye. The feeding value of rye was improved by pelleting, since the daily gain of 0.75 kg obtained by feeding a 30% rye, pelleted ration equalled that from pigs fed a 0% rye, non-pelleted ration.

Choice Feeding

The experiment described here was designed to test the proposition that lambs, given access to two feeds, as a choice, one abundant in crude protein (CP), the other deficient, can both select a diet which supports their potential growth rate and which avoids excesses of protein intake.Twenty four Suffolk x Greyface wether and females, at a mean liveweight of 20.2 kg (s.e. 0.6) were individually housed and their feed intake and liveweight recorded weekly.The four pelleted feeds used were highly digestible and had estimated energy yields of 10.5 MJ ME/kg freshweight. The basal feed (A) was made from equal parts barley and sugar beet pulp plus a vitamin/mineral mix. It contained 91 g CP/kg FW. Feed D was made by substituting fishmeal for the barley in feed A such that it contained 383g CP/kg. Feed B contained one third D and two thirds A and contained 182g CP/kg. Féed C contained two thirds D and one third A, giving a CP content of 266g CP/kg. Thus each of the four feeds A, B, C and D could be described in terms of either the proportion of feed A or the crude protein which it contained.Four lambs were offered feed A alone, and four lambs received feed B only. Twelve of the lambs were given ad 1ibitum access to both the basal feed A and one of the three other feeds B, C and D, for ten weeks. Four lambs were offered a choice between feed B and feed D for four weeks.

SummaryExperiments were made to evaluate the feeding value of undecorticated (UCS) and decorticated (DCS) cottonseed cakes and defatted DCS for egg-type starter, broiler starter and finisher diets for chicks. The results showed that UCS on average contained 22% crude protein, 0·06% free- and 0·33% bound-gossypol and 4·9% available carbohydrate. The corresponding values for DCS were 38, 0·04, 0·63 and 9·5%, respectively. Average metabolizable energy (ME) content of UCS, DCS and defatted DCS was 7·94, 11·77 and 9·42 MJ/kg, respectively. Apparent protein digestibilities of UCS, DCS and defatted DCS were 42, 47 and 36%, respectively. Although UCS had no effect on growth rate of egg-type and meat-type chicks when fed as 15% of the diet, feed conversion was adversely affected. Feeding DCS to broiler starter and finisher chicks as 30% of the diet, replacing groundnut cake (GN) had no effect on growth rate and efficiency of protein utilization but feed conversion was affected. The chicks of either breed were able to tolerate 0·02% free-gossypol of the diet derived from UCS or DCS without any adverse effect on growth rate and internal organs.

Potato steam peel is a by-product of the production of frozen french fry potatoes. As produced, it typically has 14% dry matter with 15% crude protein and 6% ash (dry matter basis) and a pH of 5.8. The starch is partially denatured and there is no proteolytic enzyme inhibitor activity. The feeding value of steam peel for pigs was evaluated through chemical analyses, a digestibility trial and a feeding trial. Its digestibility (%) by pigs was found to be dry matter 81.1 ± 2.8, crude protein 61.3 ± 3.7, organic matter 82.4 ± 3.0 and energy 76.8 ± 6.0. In the feeding trial carried out on a commercial hog finishing farm, feed consumption was markedly reduced when the steam peel was included at over 30% of the ration dry matter at the start of the trial. The inclusion of steam peel at 15, 20 or 25% of the ration dry matter reduced the average daily gain and feed efficiency (P < 0.05). However, it was concluded that potato steam peel can be used at up to 25% of the diet for growing fattening pigs with little detrimental effect on the level of animal performance.

Growth performance and survival of Tor putitora fry under different stocking densities were evaluated fry rearing system. The experimental period was 10 weeks from 31 December to 10 March 2019. The experiment was carried out in nine earthen ponds of 0.04 ha each under three treatments with three replications.  Thirty days old fry were stocked at the rate of 1.0X105/ha was designated as treatment- 1 (T1), 1.5X105/ha` as treatment- 2 (T2) and 2.0X105/ha as treatment- 3 (T3), respectively. Fry were fed with commercially available nursery feed containing 32% crude protein. It was observed that, lower stocking density showed highest daily weight gain in T1 (growth 0.066 ± 0.006 g/day) compared with higher stocking density in T2 (growth 0.044 ± 0.004 g/day) and T3 (growth 0.024 ± 0.003 g/day), respectively. It is also noticed that, the lower stocking showed the highest survival rate (79.66 ± 4.34 %) than the other two treatments (66.97±3.67 and 54.67± 3.12 %). The values of different water quality parameters were within the optimum ranges for the rearing of carp fry. Water quality parameters did not show significant variations in the experimental ponds under different stocking densities. Among these three stocking densities lower stocking density (T1) showed the best result compare with the other two higher stocking densities.

The study objective was to evaluate the effect of immunocastration in the period between the first and second vaccinations and subsequently between the second vaccination and slaughter on growth performance, carcass composition, meat quality, and boar taint, and compare results in immunocastrated males (IC), uncastrated boars (UCM), surgically castrated barrows (CM), and gilts (FE). The study included 70 pigs of the Duroc × (Large White × Landrace) crossbreed. Upon the overall assessment of the selected fattening indicators (average daily gain, feed intake), significant differences between CM and the other groups were demonstrated. Meanwhile, no significant differences were found between the IC, UCM, and FE groups. In this test, immunocastrates showed no negative effect from the second vaccination in relation to those carcass value indicators evaluated in comparison with UCM and FE. CM showed adversely lower carcass value parameters compared the other groups. No significant differences in pH, meat colour, drip loss, shear force, and intramuscular fat were found. The values of these indicators obtained for IC converged with those measured in UCM and FE. It was demonstrated that immunocastration prevented the occurrence of undesired boar taint. Androstenone decreased by 77% and skatole by 71% in IC as compared to UCM.

Sets of twin lambs from both sexes representing 11 genetic groups were fed either concentrate (HE) or roughage (LE) diets from weaning to 32 kg liveweight. One lamb from each set received the HE diet while the other received the LE diet. Data on average daily gain (ADG), relative ADG (RADG) and feed conversion ratio (FCR) were analyzed to test for the presence of a genotype × diet interaction; this effect was significant for RADG. Although the ranking of the genetic groups with respect to RADG depended upon diet, the group ranking highest on HE was also the highest on LE. The set of twins × diet interaction was not significant for ADG or RADG. The results support the present practice in test stations of feeding lambs concentrate rations to identify their potential for growth and basing growth comparisons on a within genetic group basis.

SUMMARYThe feeding value of three forms of acid-treated moist barley, viz. 26 % moisture and either rolled or plate-milled, and 29 % moisture plate-milled, was compared with that of dried hammer-milled barley for growing pigs from 23 to 87 kg live weight. Two feeding experiments were undertaken, one in which individual pigs were given the same amount of dry matter from all the diets, while in the other, groups of pigs were fed ad libitum. Digestibility of the diet was determined in a third experiment.In both feeding experiments differences between treatments in efficiency of utilization of dry matter in the feed were significant (P<0·05), that for the diet containing dried barley being approximately 5% better than the other three. There were no significant differences between treatments in intake of dry matter, rate of growth and carcass quality of the pigs. However, pigs fed on dried barley apparently grew more rapidly than those given any of the acid-treated moist barleys. Differences in digestibility of the diets were very small and not significant except for crude protein. Differences in digestibility of protein (P<0·05), however, were not consistent with differences in efficiency of conversion of dry matter in the feed.

The present study was conducted to investigate the effects of dietary supplementation of selenium from different sources on the growth performance, nutrient digestibility, and blood immune indices of piglets orally challenged with Salmonella typhimurium (ST). In a 2 × 2 factorial arrangement, 32 piglets (6.43 ± 0.54 kg of body mass) were assigned into four groups with or without dietary inclusion of sodium selenite (SS) or yeast selenium (YS) and with or without ST challenge (5 ml 1 × 109 cfu/ml ST or 5 ml saline) on d 13. In each period, YS increased average daily feed intake and average daily gain but did not reach statistical significance. During the challenged stage, piglets fed YS had higher digestibility of dry matter, crude protein, crude fat, and YS reduced the amount of Escherichia coli in feces. Additionally, YS regulated the composition of T-lymphocyte subset and influenced the production of inflammatory cytokines. In conclusion, in this study selenium-enriched yeast was more effective in enhancing nutrient digestibility, and inhibiting inflammation and oxidative stress by inducing the activity of the lymphocytes, expression of antioxidant enzymes and so on.
