The Mean

Context: Rare earth elements, the 15 lanthanide elements with atomic numbers 57 (lanthanum) through 71 (lutetium), have been reported to be capable of producing reasonable growth-promoting effects in all classes of livestock and at the same time increase milk yield and egg production. However, concentration and type of rare earth element as well as the compositions of individual elements are important factors influencing the performance enhancing effects of REE on animals. Objective: The effects of inclusion of different dietary concentrations of Cerium oxide (CeO), a Rare Earth Element on growth performance and blood parameters of female rabbits. Materials and Methods: In an 8-week feeding experiment, 32 growing female rabbits were used. The rabbits were assigned to different dietary concentrations of Cerium oxide (CeO) at 0, 100, 200 and 300 ppm. The initial weight, feed intake and final weight were determined. Blood samples were collected on the last day of the experiment for hematological and serum biochemical analyses. Results: The daily weight gain, daily dry matter intake and feed conversion ratio significantly increased (P<0.05) with increase in dietary CeO concentrations. The CeO supplemented diets generally had significantly (P<0.05) higher daily weight gain of 7.52 - 10.29 g compared with 6.65 g for those on the control diet. The mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, leukocyte and the mean differential leukocyte counts were significantly (P<0.05) influenced while the serum biochemical parameters examined, except urea, were not significantly (P>0.05) influenced by the dietary CeO. Conclusion: This study revealed that diets supplemented with CeO, particularly at 200 ppm concentration, is capable of improving body weight gain, daily dry matter intake and feed conversion ratio in rabbits without any detrimental effect on the blood parameters indicating good health status of the animals.

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), Beta-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary Beta-pro (enzymes+probiotics) or a combination of enzymes, organic acids and Beta-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.

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.

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.

The objective was to evaluate the associative effect of monensin sodium to virginiamycin on the performance, dry matter intake, apparent digestibility and ingestive behavior of steers in the initial feedlot phase. The experiment lasted for 30 days, divided into two experimental periods. Thirty-six Angus Nellore steers, non-castrated, with a mean age of 10 months and an average weight of 300 kg, were divided into 18 pens. Animals were assigned to three treatments with six replications each, with the inclusion of the following additives: T1-monensin sodium, dose of 200 mg day-1; T2-monensin sodium, dose of 125 mg day-1 + virginiamycin, dose of 125 mg day-1; and T3-monensin sodium, dose of 200 mg day-1 + virginiamycin, dose of 125 mg day-1. All experimental procedures were previously submitted to the UNICENTRO Committee for Ethics in Animal Experimentation (CEUA), and were approved for execution (Official Letter 021/2019). The combination of monensin sodium with virginiamycin at a dose of 200 mg + 125 mg animal day-1 showed greater (P < 0.05) average daily weight gain (1.919 kg day-1) and better feed conversion (4.27 kg DM kg of weight gain-1) compared to diets with monensin alone (200 mg animal day-1) or monensin combined with virginiamycin (125 mg + 125 mg animal day-1), even with no significant (P> 0.05) difference in DM intake, with a mean value of 7.88 kg animal day-1. Regardless of the isolated or combined supplementation of the additives, no significant differences were detected in the analysis of the feeder and feces scores, ingestive behavior, and rectal temperature or infrared thermography during the evaluation period. The combination of monensin sodium with virginiamycin at 200 mg + 125 mg animal day-1 proved to be efficient in the initial feedlot period, determined by the greater weight gain and better feed conversion observed in this study.

A 42-days trial was conducted to investigate the effect of caecotrophy on performance, apparent nutrient digestibility and blood parameters in growing rabbits. Thirty-six cross- bred rabbits with an average initial weight of 875±25 g were divided into 2 groups (collared and uncollared). The collared group was prevented access to their caecotropes (soft faeces) while the uncollared group were allowed access. Each group had 18 animals with 3 growing rabbits per group, replicated 6 times in a completely randomised design (CRD). The result of the study showed that the uncollared group had higher (P<0.05) final live weight, daily weight gain, feed intake which were, 1.76 kg, 17.00 g/day, 50.6 g/day, respectively when compared with the collared group which recorded 1.53 kg, 11.7 g/day and 41.7 g/day respectively. Also, lower (P<0.05) values were recorded for feed conversion ratio and mortality in uncollared rabbits in comparison to their collared counterparts. The ash and crude protein digestibility were higher (P<0.05) in the uncollared group. Serum total protein and albumin were higher in uncollared group while globulin was higher in collared group while Urea and AST was lower in uncollared group. Haematological parameters were not affected by caecotrophy. It can be concluded that prevention of caecotrophy has detrimental effect on the performance, nutrient digestibility and serum biochemical parameters of growing rabbits     Un essai de 42 jours a été mené pour étudier l'effet de la caecotrophie sur la performance, la digestibilité apparente des nutriments et les paramètres sanguins chez les lapins en croissance. Trente-six lapins croisés d'un poids initial moyen de 875±25 g ont été divisés en 2 groupes (à collier et non-collier). Le groupe à collier a été empêché d'accéder à leurs caecotropes (excréments mous) tandis que le groupe non collier a été autorisé à y accéder. Chaque groupe avait 18 animaux avec 3 lapins en croissance par groupe, répliqués 6 fois dans un design complètement randomisé (CRD). Le résultat de l'étude a montré que le groupe non collier avait un poids réel final plus élevé (P<0.05), un gain de poids quotidien, une consommation d'aliments qui étaient de 1.76 kg, 17.00 g/jour, 50.6 g/jour, respectivement par rapport au groupe à collier qui enregistrait respectivement 1.53 kg, 11.7 g/jour et 41.7 g/jour. De plus, des valeurs inférieures (P<0.05) ont été enregistrées pour le ratio de conversion des aliments et la mortalité chez les lapins noncollier par rapport à leurs homologues à collier. La digestibilité des cendres et des protéines brutes était plus élevée (P<0.05) dans le groupe noncollared. La protéine totale de sérum et l'albumine étaient plus élevées dans le groupe noncollier tandis que la globulin était plus élevée dans le groupe collier tandis que l'urée et l'AST étaient plus bas dans le groupe noncollier. Les paramètres hématologiques n'ont pas été affectés par la caecotrophie. On peut conclure que la prévention de la caecotrophie a un effet néfaste sur la performance, la digestibilité des nutriments et les paramètres biochimiques sériques des lapins en croissance

Two trials were conducted aiming to determine the chemical composition, the digestibility of nutrients and energy from dehydrated cashew apple meal, as well as to evaluate the effects generated by including increasing levels (0, 10, 20, 30, 40 and 50%) of this ingredient in growing rabbit feed, on performance, carcass characteristics and economic evaluation. In the digestibility trial, were used 24 rabbits with 55 days of age, distributed in a completely randomized design with two treatments and twelve repetitions, being one reference feed and the other test feed, composed by 70% of the reference feed and 30% DCAM. The coefficients of the dry matter digestibility, crude protein and gross energy of the DCAM were, respectively, 67.79; 30.03 and 48.61%. The digestible dry matter, digestible protein and digestible energy, based on dry matter, were, respectively, 59.55%; 4.76% and 2,119.66 kcal/kg. In the second trial, 120 mixed breed rabbits were used, with an average of 45 days of age and weight 1143 ± 153g. The animals were distributed in a completely randomized design, with six treatments and ten repetitions with two rabbits of the same sex per cage. It was observed that the inclusion of DCAM did not affect (P > 0.05) the feed intake, but reduced (P < 0.05) the feed conversion efficiency, as well as a linear reduction in carcass yield. A quadratic effect on daily weight gain and the ratio meat/bone was observed, with better inclusion level estimated at 25.31 and 24.65%, respectively. The inclusion of DCAM linearly improved economic viability to the level of 50%, however not to harm the weight gain and the ratio meat/bone, it is recommended to include up to 25%.

The objective of this study was to evaluate the efficacy of replacing oat hay with coffee husk for the feeding of confined lambs. In this study, 24 male Texel lambs of approximately 60 days of age and with a mean ± standard error weight of 21.95 ± 5.81 kg were examined. Their diet was composed of 30% oat hay and 70% concentrated feed per kilogram of dry matter. The experimental design was randomized and included four treatments (0, 7.5, 15, and 22.5% of coffee husk in the total dry matter), with six replicates of each treatment. The animals were slaughtered when they reached a mean live weight of 32 kg. There was no significant difference in dry matter intake and mean daily weight gain (which were 197 g day-1) among treatments. The mean daily weight gain (DWG) was not significantly affected (P > 0.05) by the replacement of oat hay with coffee husk in the diet, with the overall mean DWG being 215.05 g day-1. There were no significant differences (P > 0.05) among treatments in any of the studied carcass variables, and the mean true carcass yield was 53.9%. The lambs presented a mean finishing score of 2.96 (on a scale of 1 to 5) and a conformation of 4.21 (on a scale of 1 to 6), characterizing them as good carcasses. In terms of economic viability, the 7.5% diet stood out as the one that had the highest profitability, generating a profit of $ 3.25 USD per kg of carcass produced. Coffee husk can therefore replace oat hay in the feed of finishing lambs in concentrations of 0.075 to 0.225 kg kg-¹ of total dry matter with biological and economical efficacy and generating good commercial carcasses.

We assessed the productive performance, blood parameters, and carcass characteristics of young crossbreed dairy bulls kept in feedlots and fed with diets containing 0, 60, 120, and 240 g/kg of crude glycerin, replacing a mixture of ground pearl millet grain (50%) and babassu mesocarp bran (50%). Twenty-four bulls with an average age of 24 months and an average initial weight of 390 ± 31.5 kg were used. The experimental design was completely randomised with six replications. Dry matter and digestible energy intake were not influenced by diets. Feed conversion linearly decreased with increasing glycerin levels. The increase in the levels of glycerin resulted in a linear increase in blood glucose and in average daily weight gain. Carcass weight was not affected, but trimming fat increased and carcass yield decreased linearly, with increasing glycerin levels. The addition of crude glycerin at levels up to 240 g/kg of dry matter to diets containing babassu mesocarp bran and ground pearl millet grain increased the performance of young feedlot bulls, and improved feed efficiency and carcass subcutaneous fat thickness.

Valine belongs to the group of branched-chain amino acids, has an important structural role and is primarily deposited as body protein. The present study evaluated the effects of valine in diets of juvenile Nile tilapia. A total of 216 juveniles with weight of 21.40 ± 0.42 g and length of 10.07 ± 1.00 cm were distributed into 18 aquarium in a completely randomized design with six treatments and three replicates. Six diets containing 24.30% digestible protein, 3,100 kcal/kg digestible energy, and increasing valine levels (0.54; 0.63; 0.72; 0.81; 0.90; 0.99%) were prepared. The following factors were evaluated: performance, chemical composition, blood hematological and biochemical, and skeletal muscle development. Differences were observed in productive performance between treatments for weight gain, daily weight gain and apparent feed conversion, where inclusion levels from 0.81% to 0.99% provide better performances. According to the equation of quadratic regression, the inclusion of 0.86% of valine provided greater weight gain. Regarding the hematological and biochemical parameters, there were differences among the treatments for hemoglobin, triglycerides, and cholesterol. Not difference was observed for the chemical composition and muscle fiber growth. It is recommended the inclusion of 0.86% of valine in the diet of juveniles of Nile tilapia because it provides greater weight gain.

Groundnut Shell

The study was conducted to assess the chemical composition of alkali treated groundnut shells and their effects on growth and serum biochemical parameters in Yankasa rams. A total of 4 Yankasa rams where used to conduct the experiment in a 4×4 Latin square design. Four diets (14% crude protein) were formulated to contain untreated groundnut shell (UTGNS), urea treated groundnut shell (UGNS), lime treated groundnut shell (LGNS) and urea-lime treated groundnut shell (ULGNS). Growth and blood serum parameters were measured at the end of each period. Samples of the treated groundnut shell and the experimental diets were analysed for proximate analysis, neutral detergent fibre, acid detergent fibre and lignin. The results of the chemical composition of treated groundnut shell showed that alkali chemical increased the protein, energy, and reduced the cell wall constituents of the untreated groundnut shell. Significant (P<0.05) effect were observed for daily weight gain, daily feed intake and feed conversion ratio and serum biochemical profile. Daily feed intake and daily weight gain were higher in UTGNS (183.50 g and 1110.90 g respectively); UGNS had the least feed conversion ratio (5.98). Total protein and glucose levels were above normal range of serum biochemical values for sheep while blood urea and creatinine were within normal range of values. The study revealed that dietary inclusion of treated groundnut shell did not show any negative effect on the growth performance and kidney function but indicated some signs of ailment on the activities of the liver and pancreas.
