title: [Horn-based squamous cell carcinoma, bilateral and symmetrical in cow with hormonal disorder ˗ case report]

description: ABSTRACT The objective of this study was to describe a case of bilateral and symmetrical squamous cell carcinoma from the horn base in a cow and to discuss the hormonal question, possibly involved in its pathogenesis. A 11-year-old beef cow presenting a history of progressive thinning, presence of exophytic masses at the base of both horns and anestrous for many years was assisted. An incisional biopsy of both lesions was performed for histopathological examination and hormonal dosages. Due to the clinical progression, euthanasia followed by necroscopic and histopathological examination was carried out. Histopathological examination revealed a well differentiated infiltrative squamous cell carcinoma and the hormonal dosages presented changes in luteinizing hormone, follicle stimulating and total estrogen levels. Although there are descriptions of basal squamous cell carcinoma of the horn, there were still no reports of the occurrence of the same bilateral in a cow with hormonal disorders.

title: Pediculectomy and fenestration for spinal cord decompression of the lumbar spine of a bush dog (Speothos venaticus) - case report

description: ABSTRACT A captive adult male bush dog (Speothos venaticus) was referred to our Veterinary Medical Teaching Hospital from a local zoo due to a two-week history of progressive hind limb gait impairment and ataxia, non-responsive to clinical management. Computed tomography revealed decreased disc space at L3 - L4 level, with probable disc extrusion narrowing the right side of the spinal canal, compressing the spinal cord. We opted to surgically remove the disc material using both fenestration and right lateral pediculectomy (mini-hemilaminectomy) techniques. Twelve days after surgery there was mild residual proprioceptive ataxia. Gait was fully regained with remission of the neurological deficits around the 30th postoperative day. This is - to the best of our knowledge - the first successful report of a lumbar intervertebral disc extrusion in a bush dog (Speothos venaticus) surgically treated by pediculectomy and disc fenestration.

title: Prebiotics and butyric acid can replace colistin as a growth promoter for nursery piglets

description: ABSTRACT This study aimed to assess different prebiotic concentrations and principles, in addition to calcium butyrate, aiming to replace colistin as a growth promoter. The sample consisted of 120 piglets weaned at 22 days old with mean initial weight of 5.475 ± 0.719kg. The animals were assigned to random blocks in six treatments corresponding to the use of the following dietary additives: T1) colistin (40 ppm); T2) β-glucan/mannan-oligosaccharides (0.2%); T3) calcium butyrate (0.1%); T4) β-glucan/mannan-oligosaccharides (0.1%) + fructooligosaccharides (0.01%) + galactooligosaccharides (0.09%); T5) β-glucan/mannan-oligosaccharides (0.1%) + fructooligosaccharides (0.03%) + galactooligosaccharides (0.07%); and T6) β-glucan/mannan-oligosaccharides (0.1%) + fructooligosaccharides (0.05%) + galactooligosaccharides (0.05%). The results showed no difference among treatments for the performance parameters in any of the phases evaluated. For diarrhea incidence and intensity, the results indicated that the treatments with alternative additives had similar effects as the group treated with colistin. A significant difference was found for the profile of propionic acid (0.23% colistin and 0.32%, 0.36%, 0.37% additives) and total fatty acids (0.67% colistin and 0.97% additives) values in the caecum. The supplementation with different compositions and concentrations of prebiotics and butyric acid may viably replace colistin in controlling diarrhea and modulating volatile fatty acid production in the caecum.

title: [Efficiency of oral supplementation of 1.3-1.6 beta-glucan from saccharomyces cerevisiae on the control of bovine mastitis]

description: ABSTRACT Bovine mastitis, one of the main diseases of dairy herds, is characterized by an inflammatory process in the udder. The economic and environmental impacts, as well as the residues of antimicrobial drugs have stimulated the research of novel alternative treatments for the prevention and treatment of diseases in dairy production cows. The beta-glucan is an immunomodulator agent, with potential preventive action for infectious diseases, including mastitis. This study aimed to assess the effectiveness of orally administered beta-glucan in lactating cows. 20 lactating cows were used, distributed into two groups, one control and one treatment, with 10 cows in each group. The treatment group received 5g of 1.3-1.6 betaglucan daily for 60 days, isolated from the cell-wall of Saccharomyces cerevisiae diluted into a grain meal, whereas the animals in the control group received only the ration. The California Mastitis Test (CMT), Somatic Cells Counting (SCC), daily production and assessments of fat and protein content in milk were done. There was no statistically significant difference between the groups concerning subclinical mastitis detected by CMT, SCC, milk production and composition regarding protein and fat content. It was not observed, therefore, the effectiveness of the use of purified beta-glucan orally administered on the control or prevention of mastitis in dairy cows. The results are attributed to the ruminal degradation of the product tested. It is, therefore, suggested that more research should be conducted using the 1.3-1.6 beta-glucan purified from the cell wall of S. cerevisiae by other administration means and ruminal protection technologies for the isolated beta-glucan.

title: [Protease in low-protein diets for meat-type quails containing feather meal]

description: ABSTRACT The objective of this study was to evaluate protease supplementation in low-protein diets containing feather meal (FP) on the performance and carcass yield of meat-type quails. Twenty male quails were used in a completely randomized design, in a 2 x 3 factorial scheme (with and without protease x 3 FP levels (0, 5 and 10%)), totaling six treatments (Reduced diet (RD) in 8 % of the requirement of crude protein and amino acids + 0% FP; RD + 5% FP; RD + 10% FP; RD + 0% FP + protease; RD + 5% FP + protease and RD + 10% FP + protease), four replicates of 10 quails per plot, in the phases of 8-21 days and 8-35 days of age. Interaction (P≤0.05) was observed between FP and protease levels on weight gain over the period of 8-21 days. The levels of FP influenced (P≤0.05) the feed intake and the weight gain of 8-21 and 8-35 and the feed conversion ratio of 8-21 days. There was interaction (P≤0.05) between protease supplementation and FP inclusion for body weight at 35 days. It is concluded that FP can be used up to 5% in diets for meat-type quails without protease supplementation.

title: [Phenotypic characterization of Holsteins x Zebu F1 cows from different maternal bases]

description: ABSTRACT F1 Holstein x Zebu females from different maternal bases were characterized regarding coat, depigmentation and morphometric characteristics. A total of 266 F1 female progenies from the crossbreeding of 26 Holstein bulls with females of Zebu genetic composition were used: Gir, Nellore, Guzonel, Nellogir. Frequency distribution analysis was applied for qualitative characteristics and dispersion measures and central tendency for morphometric characteristics, and means were compared by Tukey test at 5% probability. Over 60.0% of the animals had a black coat. The cows that originated from the Gir breed had a head length of 2.8cm (P&lt;0.05) higher than the Nellore females. Ear length varied (P&lt;0.05) according to the maternal base used. Cows with Nelore genes were 5.0cm taller (P&lt;0.05). The thoracic perimeter was the morphometric characteristic that had a high magnitude phenotypic correlation with weight, above 0.70, for the females of the Gir, Nellore and Nellogir maternal bases. The coat is not indicative of the maternal base used. F1 Gir-based cows had a smaller body structure than females with Nellore genes.

title: [Energy value and bromatological composition of dry residue of cassava associated with carbohydrases for grower broilers]

description: ABSTRACT The energetic values and the bromatological composition of the dry residue of cassava (DRC) were determined for growing broilers with or without carbohydrase enzymes. The treatments were distributed in a 2x4 + reference diet factorial scheme, with one RD without addition of DRC and four experimental treatments with 10, 20, 30 and 40% inclusion levels of RSF and supplementation or not with carbohydrases. The chemical composition found for DRC in natural matter was 89.86% dry matter, 0.98% crude protein, 3519kcal kg-1 gross energy, 0.19% ether extract, 27% neutral detergent fiber, 19.5% of acid detergent fiber, 0.33% of calcium, 0.43% of phosphorus, 0.46% of potassium and 0.12% of magnesium. The use of carbohydrase resulted in an increase of 173 and 213kcal kg-1 in EMA and EMAn values, respectively, resulting in 1828kcal kg-1 EMA and 1840kcal kg-1 EMAn. It was concluded that the highest levels of AME and AMEn were found for the mean inclusion level of the DRC of 35% and that enzymatic supplementation may promote the increase of these parameters by up to 12% in broiler diets in the growth phase.

title: Nutritional, behavioral and performance parameters of F1 Holstein x Zebu cows at different lactation stages

description: ABSTRACT The objective of this study was to evaluate the different lactation stages of F1 Holstein x Zebu cows on intake and digestibility of nutrients, nitrogen use efficiency, feeding behavior and performance. Thirty-six F1 Holstein × Zebu cows with initial body weight (BW) of 482±43kg were used. The early, mid and late lactation stages were characterized after 50±13, 111.5±11.75 and 183.0±17.5 days in milk, respectively. A completely randomized design with three lactation stages and 12 cows in each treatment group was used. Dry matter intake (P=0.01) was higher in late lactation. Milk yield (P&lt;0.01) was 24.17% higher in early lactation than in other stages. Body weight was lowest in mid-lactation cows (465.63kg; P&lt;0.01). The feed efficiency was 23.36% higher in early lactation than in other stages (0.82kg of milk/kg of DM). F1 Holstein x Zebu cows have increased dry matter intake in late lactation. Milk yield and feed efficiency in early lactation were benefited by changes in feeding behavior, such as increased rumination time.

title: [Parameters of bone of meat-type quail supplemented with different levels of vitamin A from 15 to 35 days of age]

description: ABSTRACT This study evaluated the effect of using increasing levels of vitamin A on bone parameters in meat-type quails from 15 to 35 days old. A total of 1520 unsexed quail with an average initial weight of 85g distributed in a completely randomized design, totaling eight treatments with five replicates and 38 quails per experimental unit were used. The treatments consisted of eight vitamin supplementation levels A (0; 4,500; 6,000; 7,500; 9,000; 10,500; 12,000 and 13,500IU / kg diet). The experimental period was 15 to 35 days of age. The bones analyzed showed a linear reduction to the Seedor index, bone strength and ash content of the femur and tibia according to vitamin supplementation levels Vitamin A supplementation for cutting quails from 15 to 35 days of age showed negative results for bone quality, with the need for more studies on its antagonism to vitamin D.

title: Genetic parameter and genetic trend estimates for reproductive traits in Wistar rats

description: ABSTRACT The aim of this study was to estimate genetic parameters and genetic trends for reproductive traits in Wistar rats. A total of 1,167 data records from 283 females over six generations of monogamous mating pairs was used. Heritability and genetic correlation were estimated through Bayesian inference and genetic trends were calculated by linear regression of breeding values over generations. Heritability estimates for litter size at birth (LS), calving interval (CI), pup mortality (PM) and maternal cannibalism (CAN) presented low magnitude, ranging from 0.01 to 0.13. CAN presented high and positive genetic correlation with LS and PM (0.77 and 0.78, respectively). On the other hand, all the other estimated genetic correlations were not significant. Genetic trend was positive for LS (+0.0900 pups per generation), and negative for PM and CAN (-1.0085 and -0.5217 pups per generation, respectively). For CI the genetic trend was not significant. It is recommended to increase selection intensity on dams in this Wistar rat population in order to accelerate the genetic progress.
