 This study aimed to evaluate the performance, efficiency and economic viability of different supplements for dairy heifers on Brachiaria decumbens pasture. Twelve heifers with 186 ± 30.5 kg average weight were divided in three groups of four animals. The treatments were mineral salt ad libitum; 0.4 kg animal-1 day-1 proteined salt and 1.0 kg animal-1 day-1 multiple supplement. The experimental design was randomized blocks, with the contrasts considered significant at 5% probability. There was greater (p < 0.05) body weight and higher daily weight gain in animals supplemented with proteined salt or multiple supplement, compared to supplemented with mineral salt. There was no difference (p > 0.05) in any of the performance parameters between proteined salt and multiple supplement. The use efficiency was 1.31 and 0.61 for proteined salt and multiple supplement, respectively. The cost per kg weight gain in treatments with mineral salt, proteined salt and multiple supplement was R$ 0.67, R$ 0.68 and R$ 1.25, respectively. The use of proteined salt or multiple supplement provides superior performance than mineral salt in crossbred heifers. However, the proteined salt has higher utilization efficiency and economic advantage.

This work was carried out to evaluate the effect of supplements based on non-protein nitrogen (NPN) as: urea, amirea and multinutritional block, on live weight gain and cost analysis for cattle kept in pastures. During a period of 104 days(April to July 2004), 40 crossbreed bulls, uncastrated and initial average weight of 379kg, were allocated into 4 paddocks with Brachiaria brizantha cv. Marandu, in continuous pasture system receiving, in troughs, the following treatments: mineral salt (control), protein supplement containing amirea, protein supplement containing urea and multinutritional block. The experimental design used was randomized blocks with repetition within the block. Results of availability bromatological composition of pasture, supplement consumption and daily weight gain of animals were evaluated in two experimental sub-periods: 0 to 45 and 45 to 90 days. In the first sub-period, there was no effect of treatments (P>0.05) on daily weight gain but in the second sub-period, the multinutritional block showed smaller (P<0.05) weight gain than the ones which were similar among themselves, being: 0.60; 0.59; 0.61 and 0.22kg/animal/day, respectively, for the treatments with mineral salt, amirea, urea and multinutritional block. Before these edafoclimatic conditions, the period and duration of the experiment, the supplementation with mineral salt provided the higher profit.

Randomized Design

In a 56-day feeding trial, an experiment was conducted to determine the effects of replacing maize with different levels of ensiled cassava root-leaf blends (ECRLB) on growth, carcass yield, blood profile and economics of production of weaner rabbits. Five experimental diets were formulated and fed to the animals; diet 1= a maize based diet (control diet), diet 2= 30% maize + 10% ECRLB, diet 3 = 20% maize + 20% ECRLB, diet 4= 10 % maize + 30% ECRLB, diet 5= 40% ECRLB. A total number of forty weaner rabbits with an initial average weight of 574.09g±20.03g were randomly allocated to the five dietary treatments in a completely randomized design (CRD) with eight animals per treatment. Data were collected on growth indices, economics of production, carcass characteristics and blood profile Increased (P<0.05) weight gain was observed as the percentage inclusion of ECRLB increased. Rabbits on diet 4 (10 % maize + 30% ECRLB) and 5 (40% ECRLB) recorded the highest (P<0.05) daily weight gain with a corresponding highest (P<0.5) final body weight. Similar FCR were recorded across the treatments Economics of production of animals on diets containing 30 and 40% ECRLB was the best (P<0.05). Carcass indices were not significantly (P>0.0) affected by the experimental diets. Rabbits fed ECRLB recorded lower (P<0.05) serum cholesterol and higher (P<0.05) serum glucose concentration compared to control. In conclusion dietary inclusion of ECRLB up to 40% improved performance and did not show any deleterious effects on all indices examined and is recommended.     Au cours d'un essai d'alimentation de 56 jours, une expérience a été menée pour déterminer les effets du remplacement du maïs par différents niveaux de mélanges racines-feuilles de manioc ensilées (le 'ECRLB) sur la croissance, le rendement de carcasses, le profil sanguin et l'économie de la production de lapins sevrés. Cinq régimes expérimentaux ont été formulés et nourris aux animaux ; régime 1= régime à base de maïs (régime de contrôle), régime 2= 30% maïs + 10% ECRLB, régime 3 = 20% maïs + 20% ECRLB, régime 4= 10% maïs + 30% ECRLB, régime 5= 40% ECRLB. Un nombre total de quarante lapins sevrés d'un poids moyen initial de 574,09 g±20,03 g ont été attribués au hasard aux cinq traitements diététiques dans une conception complètement randomisée (CRD) avec huit animaux par traitement. Des données ont été recueillies sur les indices de croissance, l'économie de la production, les caractéristiques de la carcasse et le profil sanguin. Le gain de poids accru (P<0,05) a été observé à mesure que l'inclusion en pourcentage de l'ECRLB augmentait. Les lapins de l'alimentation 4 (10 % de maïs + 30 % d'ECRLB) et 5 (40 % d'ECRLB) ont enregistré le gain de poids quotidien le plus élevé (P<0,05) avec un poids corporel final correspondant le plus élevé (P<0,5). Les 'FCR' similaires ont été enregistrés à travers les traitements Économie de la production d'animaux sur les régimes contenant 30 et 40% ECRLB a été le meilleur (P<0,05). Les Indices carcasse n'étaient pas significativement (P>0,0) affectés par les régimes expérimentaux. Les lapins nourris à l'ECRLB ont enregistré un taux de cholestérol sérique inférieur (P<0,05) et une concentration plus élevée de glucose sérique (P<0,05) par rapport au contrôle. En conclusion, l'inclusion alimentaire de l'ECRLB jusqu'à 40 % a amélioré les performances et n'a pas montré d'effets délétères sur tous les indices examinés et est recommandée.

Average Weight Gain

Honeybee (Apis mellifera) colonies hived in beehive materials that had been sterilised by gamma irradiation had an average weight gain of 29.3 kg while those housed in untreated hives had an average gain of 27.1 kg.Bees sampled from both the treated and untreated colonies were examined for the presence of Nosema apis and virus, causitive organisms of stress related diseases, at the end of the season. No significant differences were found. The slight increase in weight (2.2 kg) of the sterilised colonies was not sufficient to justify the cost of prophylactic sterilisation of beehive equipment.

Sixteen crossbred pigs (Large Whie x Landrace x Hamoshire) were used in two feeding trials to evaluate the replacement value of brewers yeast slurry-maize offal mixture (BYS-MO) for full fat soybean (FFSB) and maize in the diets of pigs, and in addition to determine carcass characteristics in experiment 2. In experiment 1 four isocaloric (3250 Kcal/kg) and isonitrogenous (18% crude protein maize - full - fat soybean based diets containing 0, 22.75, 40 and 59.15% of a 1.5: 1 (weight/weight) mixture of BYS_MO were fed ad libitum for 30 days. Parameters concluded included daily feed intake, daily weight gain, feed to gain ratio, protein efficiency ratio, cost per kg weight gain, linear and jointed carcass parameters and weights of internal organs. Due to the high protein content (44.3% of CP) of BYS, the BYS_MO mixture gave a product whose protein content of 34.3% was close to that of FFSB (36.4% CP). There were no significant differences (P>0.05) among treatments in all the parameters measured. However, the cost of feed was lower for the diets containing BYS-MO than the control diets in both experiments, thereby reducing the cost per kg weight gain from #129.20 to #96.20, #84.00 and #43.50 respectively for diets i, ii, iii and iv in experiment 1 and from #133.37 to #116.38, #109.77 and #108.06 respectively for diets i, ii, iii and iv in experiment 2. The 1.5:1 (weight/weight) brewers yeast slurry-maize offal mixtutre can replace up to 40 to 59% of maize and full fat soybeans in diets for weaner-grower pigs and finishing pigs withoutv any adverse effects on performance and carcass quality.

The present study was conducted for two months between November 2019 and December 2019 to investigate the growth performance of Nile Tilapia fed with diets containing soyabean 100% (T1), soyabean and Achatina fulica: 50/50% (T2) and A. fulica 100% (T3). The experimental diets were formulated with 45% crude protein content. The stocking density was 30 fingerlings per tank of size 1m*1m*0.8m with three replications for each treatment. The tanks were stocked with the fingerlings of uniform size 9 ± 677 cm and weight 24 ± 0.66g. The experimental fishes were fed twice a day at 5% of their body weight. No significant differences (p˃0.05) in average weight gain, apparent feed conversion ratio (AFCR), daily weight gain, gross fish yield and net fish yield were observed. The study revealed that Giant African Snail (GAS) can be used either as partial or total replacement for soyabean as protein source for the fish. The use of harmful pest A. fulica in fish feed shows bright prospect in reducing the feeding expenses together with its suitable management.

Livestock systems require a thorough analysis of zootechnical and financial indicators. In this sense, the objective of this study was to evaluate the bioeconomic performance of feedlot bulls with different genetic groups in 2012 and 2013. The experiment was carried out on a farm in Paragominas, State of Pará. The confined animals belonged to the Nellore (NE), ½ Angus ½ Nellore (AN) and ½ Charolais ½ Nellore (CH) breeds. The indicators analyzed were the cost of production and economic indicators. Additionally, zootechnical indicators were evaluated, being considered NE, AN, and CH as treatments in a completely randomized design. The financial results of the total production cost were R$ 118,493.21 in 2012, and R$ 111,166.35 in 2013, and the profitability obtained was 11% in 2012 and 8% in 2013. Regarding the zootechnical indicators, the CH genetic group showed superiority (P 0.01) compared to the NE genetic group for the variables initial weight (IW), final weight (FW), weight gain (WG), average daily weight gain (DWG), and carcass yield (CY). The confinement proved to be economically viable, with positive margins and satisfactory profitability, and the CH genetic group had the best indicators and the highest increase in the final revenue of the activity.

The effect of feeding graded levels of toasted banban ground out meal on rabbit weaners was investigated. A total of fifty white rabbit weaners of 6 - 8 weeks with an average weight of 366,7 gwere fed the graded level of tested bambara nut meal at 0. 5, 15, 25 or 35% inclusion level in a complete randomized design experiment for a period of six week. The final live weight, daily feed intake were not influcticed (P>0.05) by the level of bambara nut meal in the diet. However, positive influence of the graded level of bambara nut meal was observed on the rabbit daily weight gain, feed efficiency dressed carcass, dressing percentage and ment: bone ratjo. Rabbits on the 25 and 15% bambara nut inclusion levels were found to have similar (P>0.05) daily weight gain and dressing percentage with the control ration. Rabbit on the 5% bambara nut level diet had the least feed efficiency (0.22) and meat: bone ratio (3.6), while the dressed weights of rabbit fed the diet containing 25% bambara nut meal had the highest dressed carcass weight (501.6g). Rabbits' carcass cut-up parts as well as internal organs (liver, heart, kidneys and lungs) were not influenced by the dietary levels of bambara nut meal. But the pelt weight, empty gut weight, lipid and moisture contents were significantly (P<0.05) influenced by the levels of bambara nut meal in the diet.

Probiotic Product

Twenty Lithuanian Black-and-White calves (10 bulls, 10 heifers) were used to evaluate the effects of the supplemental probiotic product, Enterococcus faecium M74 (2.4 g/day/calve), added to fresh milk and skimmed milk in a 56 day-study. The probiotic was administered by dietary supplementation to first group of calves and their respective pens (probiotic group), whereas the second group (control group) received no probiotic supplementation. The results of this trial indicate positive effects of the probiotic product Enterococcus faecium M74. The actual percentage of calves with diarrhoea was reduced from 50 % to 20% among the calves fed the pre-and probiotic diet. Probiotic supplementation reduced the faecal count of clostridia and enterococci. The calves fed Enterococcus faecium M74 weighed more at 20, 40 and 62 days of age by 4.9%, by 9.7% (P &lt; 0.05) and by 9.4% (P &lt; 0.01), respectively, than the control calves. The calves fed Enterococcus faecium M74 had increased daily weight gains compared with the calves not fed a probiotic product. The average weight gain and the daily weight gain of the probiotic-supplemented calves were by 7.8 kg (P &lt; 0.01) and by 0.14 kg higher (P &lt; 0.01) compared with the control calves. The calves given the Enterococcus faecium M74 also had forage and total DM intakes that were numerically higher than those fed the control diet, without any additive. During the 56 days experimental period, the average feed conversion rate was improved by 12.9% in the probiotic-treated group.

Positive Effect

The effect of four levels of inclusion (0; 450; 900 and 1,350g T-1) of Ractopamine hydrochloride was assessed concerning weight gain, feed conversion, dry matter intake, carcass traits and quality of castrated male cattle meat in confinement. Forty Nellore steers were used, with an average age of 26 months and initial average weight of 423.4±2.7kg, in a randomized block experimental design with four treatments and ten replications. The diet was fixed with the ratio of forage to concentrate dry matter of 75.3:24.7. A Linear positive effect observed was the inclusion of Ractopamine on daily weight gain and linear negative effect on feed conversion, highlighting the improvements with the increasing inclusion of Ractopamine hydrochloride. In relation to carcass traits, the linear effect was negative for fat thickness and no differences were found regarding the hot carcass weight ; carcass yield; area, width and depth of rib eye area of the Longissimus dorsi muscle, and noble courts. In relation to dry matter intake, the comparison of the treatments demonstrated that Ractopamine didn't influence negatively, which highlights its positive effect on the animal performance. The use of Ractopamine improves performance and decreases de amount of superficial fat in male nellore carcass in confinement.
