Abstract
The present study was designed to evaluate the association of polymorphisms in bovine trafficking protein particle complex subunit 9 (TRAPPC9) and cluster of differentiation 4 (CD4) genes with milk production and mastitis resistance phenotypic traits in a different cattle population. Three single nucleotide polymorphisms (SNPs) (SNP1 Position: Chr14:2484891, SNP2 (rs110017379), SNP3 Position: Chr14:2525852) in bovine TRAPPC9 and one SNP (Position: Chr5:104010752) in CD4 were screened through Chinese Cow's SNPs Chip-I (CCSC-I) and genotyped in a population of 312 Chinese Holsteins (156: Mastitis, 156: Healthy). The results were analyzed using the general linear model in SAS 9.4. Our analysis revealed that milk protein percentage, somatic cell count (SCC), somatic cell score (SCS), serum cytokines interleukin 6 (IL-6) and interferon-gamma (IFN-γ) were significantly (P < 0.05) associated with at least one or more identified SNPs of TRAPPC9 and CD4 genes. Furthermore, the expression status of SNPs in CD4 and TRAPPC9 genes were verified through RT-qPCR. The expression analysis showed that genotypes GG in SNP3 of TRAPPC9 and TT genotype in SNP4 of CD4 showed higher expression level compared to other genotypes. The GG genotype in SNP2 and TT genotype in SNP3 of TRAPPC9 were associated with higher bovine milk SCC and lower IL6. Altogether, our findings suggested that the SNPs of TRAPPC9 and CD4 genes could be useful genetic markers in selection for milk protein improvement and mastitis resistance phenotypic traits in dairy cattle. The CCSC-I used in current study is proposed to be validate in different and large population of dairy cattle not only in China but also in other countries. Moreover, our analyses recommended that besides SCC and SCS, the association of genetic markers could also be considered with the serum cytokines (IL-6, IFN-γ) while selecting genetically mastitis resistance dairy cattle.

Abstract
ABSTRACT: Mastitis represents an important health problem for Santa Inês breed, causing losses to the producer, due to loss of ewes or the decrease in weight gain of lambs. The aim of this work was to assess the health of the mammary gland of Santa Inês ewes at the drying and puerperium and to investigate the efficacy of a dry-off therapy with gentamicin. In this study, 64 ewes were divided in a control group (GC) and treatment group (GT), and the health of the mammary gland was assessed at the drying and puerperium. The GT ewes received 250mg of gentamicin (Gentocin® DryCow/Schering-Plough, product indicated for use in dairy cows) in each mammary half. For diagnosis, clinical examination, California Mastitis Test, somatic cell count and milk culture was performed. In the GC, of the 45 (70.3%) healthy mammary halves at the drying, 12 developed subclinical mastitis and nine clinical mastitis at the puerperium. In the GT, among 51 (79.7%) healthy mammary halves at the drying, six developed subclinical mastitis and 11 clinical mastitis at the puerperium. No association was observed between treatment and the occurrence of mastitis at puerperium. Of the 19 (29.7%) mammary halves of the GC that presented subclinical mastitis at the drying, three remained with subclinical mastitis and five developed clinical mastitis at the puerperium. In the GT, of the 13 (20.3%) mammary halves that had subclinical mastitis at the drying, four remained with subclinical mastitis and four developed clinical mastitis. No association was observed between treatment and cure or persistence of mastitis at the puerperium. The main microorganisms isolated, at the drying and puerperium, from animals with subclinical or clinical mastitis were Staphylococcus spp., predominantly coagulase negative Staphylococcus (CSN). At the puerperium, 29 cases of clinical mastitis occurred, 19 with isolation, where 10 were CNS and six S. aureus. Mannheimia haemolytica was isolated in one case of subclinical mastitis and other of clinical mastitis. News protocols and different ways of handling at drying and at puerperium must be investigated.

Risk factors of teat-end hyperkeratosis and its association with udder health in dairy ewes. J DAIRY RES 2018; 85:44-49.

Abstract
This study tested the hypotheses that machine milked dairy sheep have a high prevalence of teat-end hyperkeratosis (TEH), which contributes to udder health problems. A random sample of 1360 milking ewes from 28 dairy sheep farms was monitored. Milking procedures, milking parlour characteristics and maintenance were recorded during a designated on farm audit; records were obtained through observations and interviews with farmers. Number of ewes/milker, ewes/milking unit and milkings/milking unit were calculated. Vacuum level, pulsation rate and ratio were measured. Four combinations of vacuum level and pulsation rate were defined; <40 kPa and <150 cycles/min (VP1), <40 kPa and ≥150 cycles/min (VP2), ≥40 kPa and <150 cycles/min (VP3), ≥40 kPa and ≥150 cycles/min (VP4). California Mastitis Test (CMT; scores 0–4) was done on all ewes. Then the udder of each ewe was assessed for TEH (scores 1–4) and ewes were assigned into three groups according to TEH severity (no or mild, medium and severe TEH). Severe TEH (scores 3 and 4) prevalence at teat-level was ca. 13%. TEH severity was associated with the combination of vacuum level and pulsation rate; ewes milked with VP4 combination were more likely to have a one-level increase on TEH severity compared to ewes milked with VP2 and VP3 combinations. More ewes/milker and less ewes/milking unit increased the likelihood of a one-level increase on TEH severity. Finally, ewes with severe TEH were more likely to have a one-level increase on CMT score. Therefore, our hypotheses that TEH is prevalent in dairy ewes and contributes to udder health problems were confirmed. Additionally, farmers can reduce TEH prevalence by optimising the way they milk and their milking parlour.

Abstract
The objective of this study was to evaluate different screening limits for the California mastitis test (CMT) and the somatic cell count (SCC) in previous diagnoses of subclinical mastitis in Santa Inês and Morada Nova ewes, which were reared under the same management conditions. Additionally, cutoff points were defined for SCC in accordance with the sensitivity and specificity of the test. A total of 907 mammary halves were subjected to CMT and SCC. The disease was confirmed by means of microbiological identification. Coagulase-negative staphylococci (CNS) were the microorganisms with highest occurrence. The CMT score of 1+ provided adequate sensitivity and specificity at all periods of lactation investigated. This score showed good agreement with SCC, >400,000 cells mL(-1). Higher cell counts favored higher diagnostic specificity. They can be used when producers have financial difficulties relating to treatment or culling of sheep with subclinical mastitis. However, producers should be warned about the risk of false-negative results in the flock.

Abstract
RESUMO O objetivo do presente trabalho foi avaliar diferentes indicadores inflamatórios no diagnóstico da mamite em ovinos da raça Santa Inês. Após a realização do exame físico das mamas e a prova de fundo escuro, foram coletadas e analisadas 390 amostras de leite, sendo as metades mamárias divididas de acordo com o exame bacteriológico e a prova de fundo escuro, resultando em 290 amostras negativas em ambos os exames, 90 amostras negativas à prova de fundo escuro e positivas na cultura bacteriológica, 5 amostras positivas à prova de fundo escuro e negativas ao exame bacteriológico e 3 amostras positivas em ambos os testes. Nestas amostras foram realizadas a contagem automática de células somáticas (CCS), o California Mastitis Test (CMT), a determinação da concentração hidrogeniônica (pH) e dos teores de cloreto e lactose, e ainda a avaliação do índice de cloreto-lactose. Os maiores valores preditivos foram observados para a CCS, CMT e teor de cloreto; o pH, o teor de lactose e o índice cloreto-lactose apresentaram-se como marcadores inflamatórios menos sensíveis, onde se considerou o resultado da cultura bacteriológica como padrão ouro. O exame físico não se mostrou como método diagnóstico seguro quando utilizado isoladamente, exaltando a importância da associação de outros meios diagnósticos indiretos.
