The experiment was conducted at the Experimental Farm of São Gonçalo dos Campos, belonging to the School of Veterinary Medicine and Zootecnia, December UFBA 2012 to February 2013, was used 32 crossbred goats Boer, with average body weight of 16 ± 2 kg distributed in a completely randomized design (CRD) with four treatments (0%, 33%, 66% and 100% replacement of soybean meai by cottonseed meai) and eight repetitions, with a duration of 84 days of experiment. The reason used was 50:50 roughage Tifton-85 hay and concentrate based on com meai, soybean meai, mineral salt, cottonseed meai and urea, thus providing proper nutrients to a gain of 0.150 kg / day. The amounts of offered feed and remnants were recorded daily in order to determine consumption. The animais were weighed at the beginning of the experiment and the end of the trial period for the productive performance. Chapter I - consumption, apparent digestibility, performance and feeding behavior of Boer crossbred goats fed cottonseed meai. In the evaluation of the nutrient intake ether extract showed a quadratic effect so that increased leveis of substitution of soybean meai by cottonseed meai (.122-, 131), so that the increased replacement leveis soybean meai by cottonseed meai, attributes the increase of this nutrient in the diet (2.32 to 3.68) while the cotton cake has 15.61% of ether extract, in apparent digestibility of nutrients and performance no effect, with CMS (0.778 kg) and ADG (0.100 kg / day). Ingestive behavior was no effect for feeding time (200-271 min / day), feed rate (13.91 to 18.88) and rumination efficiency (398-533 cakes), and increasing linear positive with increasing replacement for soybean meai cottonseed meai. Chapter II - Quantitative and qualitative characteristics of carcass and meat from crossbred goats boer fed cottonseed meai. The quality of the meat is not expressed in the substitution leveis except in ash content and cholesterol in mg / lOOg flesh evaluated, with an increasing and decreasing linear-linear relationship with increasing leveis of replacement for soybean meai cottonseed meai, respectively, the ash averaged 1.06 to 0.96% MS cholesterol and 50 - 70 mg / lOOg flesh attach the ether extract content of diets increased from 2.32 to 3.62, and confirmed with increasing intake of ether extract from animais to levei increased substitution. Chapter III - ruminal morphometry and production of volatile fatty acids in crossbred goats boer fed cottonseed meai. Total replacement of soybean meai by cottonseed meai in diets for crossbred Boer goats can be used in the termination of the animais without compromising the development and animal production Editora / Evento / Instituição: Universidade Federal da Bahia Tipo: Tese 2016-05-20T00:00:00Z https://repositorio.ufba.br/handle/ri/43427 Título: Regiões de variações no número de cópias (cnvr) associadas a medidas morfométricas e pontuações de morfologia e marcha em equinos da raça campolina Autor(es): Krebs, Lísia Castro Primeiro Orientador: Costa, Raphael Bermal Abstract: Morphometric measurements are a set of morphological traits relevant to the selection and genetic improvement of horses, as they directly influence conformation and functional performance. Investigating the genetic factors underlying these traits is essential to enhance selection strategies. In this context, copy number variations (CNVs) represent an important source of genomic diversity and may impact genes involved in skeletal growth and development. This study aimed to perform a genome-wide association study (GWAS) using copy number variation regions (CNVR) in Campolina horses, focusing on the identification of genomic regions associated with morphometric traits. Phenotypic data of 15 morphometric measurements were analyzed from 240 Campolina horses provided by ABCCCampolina. DNA was extracted from hair bulb samples, and genotyping was performed using the Equine Plus Illumina-70K chip (NEOGEN). Quality control excluded phenotypic outliers and genotypes with a call rate lower than 95%, resulting in 239 animals and 56,364 SNPs. CNV detection was conducted using the PennCNV software, and CNVRs were identified with CNVRuler, considering regions with at least three SNPs, minor allele frequency (MAF) greater than 0.02, CNVR separated into gains and losses, and a recurrence rate threshold of 0.1. The statistical model applied was linear regression, including sex, age at registration, and state of birth as fixed effects. Gene annotation, QTL enrichment were performed using the GALLO package in R, and functional enrichment of CNVRs (p < 0.05) was assessed using VarElect. A total of 384 CNVs were detected in Campolina horses, grouped into 212 CNVRs. For height-related traits, 12 CNVRs were significantly associated with withers height, including one exclusive region harboring the candidate gene SMARCAL1 (ECA6). For croup height, 11 CNVRs were identified, with one exclusive region containing the gene SLC39A13 (ECA12). For back height, 10 CNVRs were associated, with the candidate gene MAP2K2 (ECA7). For flank height, 24 CNVRs were significantly associated, including two exclusive regions harboring the genes SLC38A7 (ECA3) and PTPN1 (ECA22). Regarding length-related traits, for head length, 13 CNVRs were associated, one being exclusive with the gene LRRTM4 (ECA15). For neck length, 15 CNVRs showed association, including two exclusive CNVRs harboring DOCK1 (ECA1) and KIF2B (ECA11). For back-loin length, 14 CNVRs were associated, with one exclusive region containing ROR2 (ECA23). For croup length, nine CNVRs were identified, including two exclusive regions harboring PTGER3 (ECA5) and SLAIN1 (ECA17). For shoulder length, only two CNVRs were associated, harboring TSC22D1 (ECA17) and LRBA (ECA2). For body length, 13 CNVRs were associated, with four exclusive regions containing NAGEL2 (ECA1) and TCF4 (ECA8). Regarding width measurements, for head width, four CNVRs were associated, two of which were exclusive, harboring ERCC3 (ECA18) and RABGAP1 (ECA25). For chest width, 10 CNVRs were associated, including four exclusive regions containing TUBB (ECA20), TWIST1 (ECA4), and CDH9 (ECA21). For hip width, 14 CNVRs were identified, with one exclusive region harboring OSGEP (ECA1). Finally, regarding perimeter measurements, thoracic circumference showed 10 associated CNVRs, two of which were exclusive, harboring RPL26 (ECA23) and TAX1BP1 (ECA4). For cannon bone circumference, 20 CNVRs showed significant association, including two exclusive regions associated with ZNF280B, PRAME (ECA8), and CDH9 (ECA21). The findings 32 of this study indicate that CNVRs influence the morphometric traits of Campolina horses, suggesting the existence of genomic regions involved in skeletal growth and development. Furthermore, these results highlight the need for additional functional studies focusing on each candidate gene to clarify their roles in regulating these traits.

The objective of Experiment 1 was to determine the voluntary intake of nutrients and the production, quality and stage of embryonic development in Boer goats fed diet supplemented with levels of flaxseed. Experiment 2 was to determine the nutrient intake, body weight and blood biochemistry of Alpine goats fed diet contains levels of flaxseed. In Experiment 1, 24 female Boer goats were randomly assigned to one of four groups with 0, 4, 8 or 12% of flaxseed inclued in the diet. Results from Experiment 1 showed that there was no effect of diets (P>0.05) on dry matter intake. However, there was an linear increment (P<0.001) for the intake of fat and linear declined on the consumption of non-fiber carbohydrates (P<0.05). Morever, there were dieatry effects (P<0.05) on the total number of collected embryos, viable embryos and degenerate embryos as well as for the morphological quality of viable embryos and for the developmental stages of embryos. This study indicates that the inclusion of 4 or 8% of flaxseed in diets of Boer goats diet increases the number of viable embryos with incidence of lower degenerated embryos. In the experiment 2, a total of 21 Alpine goats were randomly assigned to one of the four dietary groups with 0, 5, 10 or 15% of brown flaxseed inclued in the diet. The dry matter intake decreased linearly (P<0.001) and the difference in declined was 53.49% between control and the group that had 15% of flaxseed included in the diet. However, there was no dietary effect (P>0.05) on the daily weight gain. The consumption of non-fiber carbohydrates was reduced linearly (P<0.001). The plasma concentration of lipid profile showed an increasing linear behavior (P<0.05). It is apparent that inclusion of flaxseed upto 15% in the diet of Alpine goats could meet the energy demand through increase consumption of fat, regardless of decreased dry matter intake without having an effect on average daiy gain.

Detoxification capacity through interactions between the time of autoclaving and the amount of CaO was evaluated. It was used a 5x2 factorial design, five levels of calcium oxide (0, 10, 20, 30 and 40 g / kg) and two times in autoclaving (15 and 30 minutes), with five replicates per treatment. The treatment with 10g of calcium oxide / kg of castor oil meal and autoclaving for 30 minutes promoted the disappearance of the bands that represent the subunits of ricin, being the most efficient method because less CaO was used in the process. Therefore, this method was used to detoxify the castor bean meal used for formulation of the experimental diets. 40 crossbred male sheep were used, with average weight of 25 ± 2,96kg, in a completely randomized design with four treatments and ten replicates. The diets consisted of 0, 10, 20 and 30% inclusion levels of castor meal on dry matter. Diets were formulated to be isonitrogenous, and forage:concentrate ratio was 50:50. The inclusion of castor meal in the diets of growing lambs until the level of 30% of the total diet did not affect the intake of dry matter and crude protein, averaging 1.194g and 191g respectively. However, promoted increases in intake of ether extract and neutral detergent fiber on 17% and 19% respectively. However, the consumption of non- fibrous carbohydrates linearly decreased, around 31.8%. There was a linear decrease in the digestibility of dry matter and carbohydrates both the fiber and the non-fiber fraction, with the inclusion of detoxified castor meal. However, CP and EE digestibility coefficients have not changed. The performance data of sheep fed diets containing castor meal indicated a decreasing linear trend for the variables final body weight gain in total weight and average daily gain. The levels of hepatic enzymes GGT, AST and ALT were not influenced by the inclusion of detoxified castor meal, just as the levels of albumin, cholesterol and triglycerides. Based on the evaluated results is possible to reduce the level of CaO to 10g / kg of castor meal and the autoclave time to 30 minutes using the mixed method of detoxification, and later include up to 30% of castor meal in diet of lambs.
