The aim of this study was to compare the following four genetic groups of hair sheep: Santa Inês (SI), Morada Nova (MN), Brazilian Somali (BS), and the F1 1/2Dorper x 1/2Morada Nova crossbreed on traits related to growth and parasitic infection. Thirty-three male lambs of the same age and of simple birth, under the same pre-weaning management conditions were used in the experiment. After weaning the animals were housed in a completely randomized design in paddocks made of Panicum maximum cv. Tanzania. Along the course of the research, the performance of the four groups of sheep was observed to be negatively affected by gastrointestinal parasites, but there was a genotype effect to the average daily weight gain (ADWG), where the SI and F1 genotypes presented higher values. The effects of genotype, time and genotype x time interaction were significant in weight and corporal score (CS) measurements. The BS lambs had the highest CS values throughout the experiment despite not presenting greater weight gain when compared to the SI and F1 breeds. There were also significant effects of time and genotype x time interaction for packed cell volume (PCV) and FAMACHA© score (FAM) and only the time effect was significant in the total number of eggs per gram (EPG) and total plasma protein (TPP). The MN lambs showed higher PCV values and unlike the other groups, presented a FAMACHA© score below 3 and PCV above 23% even having a higher EPG tendency, especially in the initial phase, indicating a possible higher resilience to infection caused by gastrointestinal parasites.

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 purpose of this study was to determine the effect of giving pituitary extract (EH) and probiotics ABG-O on piglets crossing to increase weaning weight, linear size of body and blood metabolites. The research material was a crossbred of landrace and duroc aged 2 weeks, as many as 24 birds. The experimental design was a completely randomized design with three treatments and eight replications. The three treatments are P0 (control), P1 (EH injection 1 mL), and P2 (injection EH 1 mL + probiotic ABG-O 2 mL). EH injections are carried out every 5 days and administration of probiotics is given orally using spoit every day until the piglets are weaned. The parameters observed were weight gain, linear size of body and blood metabolites. This data was analyzed by ANOVA and continued with Duncan test. The results of this study indicate that the average daily weight gain of crossbred piglets in treatments P0, P1, and P2 are 0.11; 0.13; 016 kg, body length (0.40; 0.45; 0.44 cm), chest circumference (0.29; 0.27; 0,30 cm), and shoulder height (0.25; 0.24; 0.25  cm). Blood glucose levels (117.31; 112.85; 117.25) and total plasma protein (4.60; 4.90; 4.80). The results of the statistical analysis showed that the EH and ABG probiotic treatments affected the UN (P<0.05) but did not affect (P> 0.05) the size of the linear body and blood metabolites. It can be concluded that the administration of pituitary extracts and ABG probiotics can increase the weaning weight of crossing piglets but does not affect the linear size of the body and blood metabolites.

The objective of this work was to evaluate the effect of sustained swimming and dietary protein levels on growth and hematological responses of juvenile pacu (Piaractus mesopotamicus). A completely randomized design was used in a 3x2 factorial arrangement, with three levels of dietary protein (24, 28, and 32% crude protein), two rearing conditions (sustained swimming or motionless water), and 15 replicates. Fish were subjected to sustained swimming at the velocity of two body lengths per second (2 BL s-1), for 45 days. The level of dietary protein and the swimming conditions affected the performance, growth, and hematological profile of pacu. Swimming conditions influenced nutritional factors, increasing daily weight gain, specific growth rate, number of erythrocytes, mean corpuscular volume, and mean corpuscular hemoglobin. Fish under sustained swimming and fed with 24% crude protein showed better growth performance, with higher specific growth rate (4.11±0.88) and higher daily weight gain (2.19±0.47 g per day). Sustained swimming can increase the productive performance of pacu and simultaneously reduce dietary protein levels.

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.

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, growing, and end periods, the effects of peppermint powder on average daily weight gain, feed conversation ratio, and mortality rate were studied. The results of the present study showed that over a production period of 42 days peppermint had a significant effect on average daily weight gain and feed conversation ratio when compared with the control group ( P < .05). The level of 4.5 g/kg had the highest average daily weight gain (52.78 g), and control treatment with 46.98 g had the least average daily weight gain among different levels of peppermint. The level of 4.5 g/kg and 6 g/kg of peppermint had the least mortality compared to control treatment during training period ( P < .05). From this experiment, we can conclude that treatment with 4.5 g/kg peppermint powder has better performance and carcass characteristics in broilers.

Increasing concern about some animal production systems has placed considerable value on humanitarian breeding systems, aimed at ensuring animal welfare and comfort. Raising calves is one of the most important stages in a milk production system. This study aimed to evaluate and compare the performance of Holstein dairy calves raised by two farming systems: conventional individual (CI) and collective with automatic calf feeder (CACF). Fourteen, 15-day-old Holstein dairy calves having an average initial body weight of 40 kg, were used. The animals were distributed in a completely randomized design with seven animals per treatment. The variables evaluated were the milk and feed intake, body weight, hip height, thoracic circumference and daily weight gain. The average milk intake was lower in the CACF (3.5 L animal-1 day-1) than CI (5.1 L animal-1 day-1) system. However, the feed intake was higher in the CACF (1.205 kg animal-1 day-1) compared to CI (0.910 kg animal-1 day-1) system. Body weight, thoracic circumference, hip height and daily weight gain were similar between the two systems. The CACF raised calves had a higher concentrate intake and lower milk intake than the calves raised under the CI system.

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.

An experiment was carried out to investigate the performance and nutrient digestibility of West African dwarf growing rams fed mixture of Panicum maximum and Tridax procumbens supplemented with Cajanus cajan leaves for 56 days feeding trial. A total of twelve WAD rams were randomly allocated to three treatments with four animals per treatment while two animals served as replicate. The experimental diet was fed at 3% body weight of individual animals while Cajanus cajan leaves were supplemented at varied inclusion levels. The results revealed that animals fed T1 recorded the least weight gain (36.96g/day) while the highest weight gain (56.42g/day) was recorded for T3. The daily weight gain of animals was significantly different across all treatments (P<0.05). The highest DMI (18.30kg) was recorded on the T1, and the least value of DMI (17.40kg) was recorded in T3. The highest feed efficiency ratio (0.18) and the lowest value (0.11) were observed in animals fed T1 and T3 diet respectively. There were significant differences (P<0.05) in the nutrient digestibility parameters of the experimental animals. The results showed that T1 (100% sole Cajanus cajan leaves) promoted the best dry matter (DM) digestibility (89.56%) which was enough to meet the production and maintenance requirement of small ruminants while the lowest value (88.67%) of DMD was recorded in T2 . The highest crude protein (CP) digestibility (13.20%) was observed in T3 diet. The highest value for crude fibre digestibility (38.95%) and the lowest value (35.35%) were observed in animals fed T2 and T1 diet respectively. In conclusion, supplementation of Cajanus cajan leaves with mixture of Tridax procumbens and Panicum maximum as basal diet for feeding sheep enhanced nutrient intake, growth performance and improved nutrient digestibility without health challenges to the animals.

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.
