The goal of this study was evaluate diets (50 or 80% of concentrate) and body biotypes (late or early) on performance, behavior, carcass condition, meat quality, and feed cost estimates in feedlot finishing Guzera beef cattle. Use of concentrates in the diet may improve performance and carcass fat scores in ruminant animals, but Guzera beef cattle may be more efficient in forage conversion, which directly influences the economic viability of the production system. We evaluated 32 non-castrated male Guzera beef cattle at 32±2 months of age. The experimental design was completely randomized with four treatments and six replicates in a 2 × 2 factorial design (2 diets × 2 body biotypes). Initial and final body weights were 459.4±31.2 kg and 566.7±40.8 kg, respectively. There was no change (P > 0.05) in dry matter intake, feed conversion, or daily weight gain when the concentrate in the diet was increased to 80%. Animals fed a diet with 80% of concentrate spent less time (P < 0.05) ruminating (17.8±6.3 vs. 6.3±2.7% of the assessed time). Body biotype did not alter the variables. The rise from 50 to 80% in the proportion of dietary concentrate increased carcass fat, with positive returns in the production process, even given the reduction in rumination, which can lead to poor welfare of animals consuming 80% of dietary concentrate. Body biotype did not affect the variables studied, but it is worth emphasizing that the age at slaughter of these animals probably influenced this result. Thus, selection of the best diet should be based on feeding cost, and in accordance with the cost estimated in this study, the diet with 80% of concentrate is the most suitable for feedlot finished Guzera beef cattle.

The effects of supplementing different urea molasses blocks to Yankasa Rams fed maize offal-based diet on nutrient intake, growth performance and economics of production were evaluated. Yankasa rams fed cowpea shell and maize offal-based diets mixed in a ratio of 1:3 supplemented with urea molasses block (UMB). The supplementary blocks were formulated to contain 0, 5, 10 and 15% urea. Twenty Yankasa rams were used for the experiment with initial body weights range of 16-20kg and randomly allocated to four treatment groups of five animals each in completely randomized designed. Data on feed and water intake, body weight change were measured. Rams were fed both the basal diet and supplements ad libitum. The result revealed no significant (P>0.05) difference in basal feed (579.38-595.18g/day), UMB (60.78-96.50g/day) and dry matter intakes (584.36-609.33 g/day) among the treatments. Rams on treatment 3 recorded the highest average daily weight gain (ADG) and feed conversion ratio (FCR) (101.43 g/day, 5.93) than those on treatment 2 (48.57 g/day, 12.37) with the least. The cost of UMB/kg was least in treatment 3 (N 46.66) compared to those on treatment 1(N 83.66), 2(N 113.05) and 4(N 50.39). Supplementation of urea molasses block improved growth performance and FCR. Urea up to 15% may be included in urea molasses blocks without any detrimental effects on performance. However, including urea at 10% in UMB gave the highest ADG and FCR and therefore may be recommended for growing Yankasa rams

ABSTRACT The use of blood metabolites (BM), fecal starch (FS), and apparent digestion of starch, (ATTSD) as indicators of feed efficiency (FE) in beef cattle in the feedlot was studied. Fourteen bulls were used, originating in an industrial cross, without a defined racial group, with mean body weight of 284.86kg, individually fed, being evaluated in a 42-day confinement system. After the evaluation, the animals were divided into two groups according to the individual FE: high feed efficiency (HE) and low feed efficiency (LE). There was a difference between the groups in the variables FE, feed conversion (FC), final weight (FW), and daily weight gain (DWG). The FE had a positive correlation with DWG, FC, and FW. There was no difference between the groups for the variables BM, FS, and ATTSD, nor was there any correlation between these variables and FE. Considering the feed cost, the HE animals proved more profitable. BM, FS, and ATTSD did not statistically show potential to be used as indicators of FE, despite the evidence of numerical differences of these variables between the different groups, tendency of correlations with FE, and discriminating function with potential assertiveness.

A 4 week experiment involving 45 growing albino rats was carried out to assess the nutritional utilization of cooked full-fat soybean (CFFS) as a major source of dietary protein relative to that of the protein concentrates fishmeal-groundnut cake mixture and the response to supplementation of the cooked soybeans with 2g DL-methionine/kg diet and/or 2g L-lysine/kg diet. Feed intake (FI), average daily weight gain (DLG),. feed conversion ratio (FCR), protein efficiency ratio (PER) and feed cost (FC) per unit live-weight gain, (FC/WG) were measured, No significant effect of the various dietary treatments was observed on PER and FCIWG. However, the incorporation of CFFS either alone or in conjunction with either of both lysine and methionine significantly improved Fl and FCR (P< 0.05) and also DLG (P< 0.01) over the control fish-groundnut meal ration. Supplementation of CFFS with lysine either alone or along with methionine appeared unwarranted as methionine supplementation alone resulted in similar or slightly better efficiency of protein (0.247) and overall feed (0.596) utilization. From the results obtained, it appears that maize-based CFFS diet supplemented with 2 g/kg DL-methionine may be applicable for lion- ruminant feeding. However, since this level of methionine supplementation only provides for 67% of rat requirement, it is suggested that further studies with higher methionine levels be conducted.

This study aims to determine the effect of fermented sago pulp in rations on performance (weight gain, feed consumption, feed conversion) and local sheep's income over feed cost (IOFC). This research was carried out in the community farms of Karang Rejo Village, Stabat District, Langkat Regency. This research started from March to June 2017. The design used was complete randomized design (RAL), with 4 treatment of 5 replications. Each replication consisted of 1 local sheep with an initial weight of 11.05 ± 0.56 kg. The treatment consisted of P1 (50% sago pulp without fermentation + forage), P2 (60% of sago pitch without fermentation + forage), P3 (50% fermented sago pulp + forage), and P4 (60% fermented sago pulp +). The observed variables were performance (body weight gain, feed consumption, feed conversion) and income over feed cost (IOFC). The results showed that the treatment of fermented sago pulp gave a very real effect (P <0.01) on daily weight gain. The mean of P1 = 33,05 g, P2 = 39,95 g, P3 = 46,57 g, P4 = 54,38g. The consumption of fermented sago pulp treatment has a real effect (P <0,01). With average P1 = 486,38 g, P2 = 548,68 g, P3 = 604,69 g, P4 = 671,11 gr. Against the conversion of fermented sago pulp fermentation treatment gave a real effect (P <0.05). With average P1 = 14.78, P2 = 13.90, P3 = 12.99, P4 = 12,49. IOFC the highest local sheep is Rp. 121.568 on treatment of P4 and IOFC lowest at treatment P1 equal to Rp.73.315. The conclusion of the research shows that the utilization of fermented sago pulp can increase body weight gain, feed consumption, local sheep feed conversion. P4 treatment economically has a better economic level than P1,P2 and P3.

Forty growing rabbits were allocated equally to five groups in a 2 x 3 factorial layout and caged individually for a 56-day trial period in hutches. They were used to compare the effects of two processing methods (unfermented and fermented) and three dietary replacement levels of Pineapple peel meal (PPM) at 0%, 12.5% and 25% of maize on weight for weight basis. Parameters evaluated during the trial period included: growth rate, feed intake, feed conversion ratio and feed cost. Results show that average daily weight gain (ADG) reduced (P<0.05) as dietary inclusion level of PPM increased, although rabbits fed PPM at 12.5% dietary inclusion level compared favourably (P>0.05) with those fed the control diet (0%). However, ADG of rabbits fed fermented PPM was statistically higher (P<0.05) than that recorded for rabbits fed unfermented PPM. No significant (P>0.05) difference was observed in daily feed intake of rabbits as a result of dietary inclusion level or processing type of PPM. Better (P<0.05) feed efficiency was recorded in rabbits fed PPM at 12.5% dietary inclusion level than those fed at 25%. Fermentation enhanced the nutritional value of feedstuff and also improved feed efficiency. Total feed cost reduced (P<0.05) by 21.39% when PPM was included in the diet at 25%. However, production result was not comparable with the control. But feeding fermented PPM at 12.5% inclusion level resulted in the best (P<0.05) economy of production. Processing type or dietary inclusion level of PPM had no significant (P>0.05) effect on dressing-out percentage of experimental animals. There were neither significant (P>0.05) effects of processing type nor dietary inclusion level on retail cuts of the rabbits fed the different experimental diets. In all feeding rabbits with diets containing fermented PPM up to 12.5% replacement level for maize optimum performance.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance

Slight Advantage

Young cattle were fed whole or cracked wheat with 20% lucerne hay, either ad lib or at a medium level, restricted to approximately 2.3% of fasted liveweight. Over 70 days, animals fed ad lib consumed 3.2 and 2.7% of their mean fasted liveweight on whole and cracked wheat respectively, and weight gains on the ad lib diet were higher than those on the medium feeding level. Cracked wheat gave 32% higher liveweight gains than whole wheat when feeding was restricted to 2.3% of fasted liveweight. However, animals offered whole wheat ad lib consumed 24% more feed, and attained the same rate of gain as those on cracked wheat. Feed conversion ratios were 7.0 and 8.8 for cracked and whole wheat, respectively. It would be economical to crack wheat only if the cost of double handling and processing 6.6 t of wheat was less than the cost of an extra 2.0 t of whole wheat. Animals fed lupins for 42 days did not consume as much as those fed wheat, but gains were only slightly lower. Lupins may be better suited to increasing the protein content of mixed rations. Only when animals were fed ad lib was there some slight advantage in adding urea to wheat rations. When whole wheat and whole oats were fed at the same restricted level, liveweight gains were higher on oats and feed conversion ratio was lower.

Abstract. The objective of this study was to determine the association of single nucleotide polymorphisms (SNPs) in selected candidate genes with fattening performance traits in a commercial cattle herd. Fifteen SNPs in 12 candidate genes (LEP, FABP4, DGAT1, TG, IGF1, IGF1R, MYF5, LGB, CAPN1, CAST, GHR, and OLR1) were evaluated in 296 purebred Holstein–Friesian bulls using PCR-RFLP (polymerase chain reaction – restriction fragment length polymorphism). Associations between each segregating SNP and genetic merit for fattening performance were quantified using linear mixed models. Traits included in the study were fattening period, final weight, dry matter intake, feed conversion rate, and average daily weight gain. Apart from the general determination of the above-mentioned traits, each trait was evaluated based on the fattening periods between five selected target body weights (W1 = 100 kg, W2 = 200 kg, W3 = 300 kg, W4 = 400 kg, W5 = 450 kg). All markers with the exception of CAPN1 530, IGF1R, TG, and DGAT1 were associated with at least one of the traits. Furthermore, novel associations were observed for LEP × GHR, IGF1 × LEP, FABP4 3691 × FABP4 2834, and FAP4 3533 × LEP interactions. The results of this study confirm some previously reported associations. Moreover, novel associations have been identified, which may be incorporated into breeding programs to improve fattening performance.
